Raytheon selected to Build New Nuclear Cruise Missile [ Trump has shares]

Raytheon to Build New Nuclear Cruise Missile ,  Arms Control Association, May 2020, By Kingston Reif

The U.S. Air Force announced last month that it plans to continue development of a new fleet of nuclear air-launched cruise missiles (ALCMs) with Raytheon Co. as the sole contractor.

“After an extensive evaluation of contractor programmatic and technical approach during…preliminary design reviews, the Air Force decided to focus on Raytheon’s design,” according to an April 17 service press release.

In August 2017, the Air Force awarded a $900 million contract to Raytheon and a $900 million contract to Lockheed Martin Corp. to proceed with development of the ALCM replacement, known as the long-range standoff (LRSO) weapon. (See ACT, October 2017.) The contracts were intended to cover a 54-month period of development after which the Air Force would choose one of the contractors to complete development and begin production.

The service’s rationale for focusing on one contractor roughly two years earlier than planned is unclear………The Trump administration is requesting $1.5 billio

Beyond Nuclear and other groups challenge Holtec’s nuclear waste plan for New Mexico

Carlsbad Current Argus 2nd May 2020, A proposed nuclear waste repository near Carlsbad and Hobbs proceeded through the federal licensing process despite protests from environmental
groups who questioned the legality of the project. Holtec International applied to the Nuclear Regulatory Commission (NRC) for a license to build and operate a facility that would temporarily store spent nuclear fuel rods in a remote location of southeast New Mexico while a permanent repository is developed.

The consolidated interim storage facility was challenged by Beyond Nuclear and other organizations who questioned Holtec’s application for suggesting the U.S. Department of Energy could take ownership of the waste.

Comment Period For Proposed Nuclear Waste Dump In New Mexico extended by 60 days

60-Day Extension Of Public Comment Period For Proposed Nuclear Waste Dump In New Mexico, KRWG, By NEWS EDITOR AND PARTNERS  MAY 2, 2020   U.S. Senators Tom Udall and Martin Heinrich, and U.S. Representatives Xochitl Torres Small, Ben Ray Luján, and Deb Haaland are welcoming an announcement from the Nuclear Regulatory Commission (NRC) that their March 20 request has been met and a 60-day extension on the public comment period will be implemented for the Draft Environmental Impact Statement for Holtec’s proposed spent nuclear fuel storage facility in Southeast New Mexico.  Here is statement from the office of Senator Martin Heinrich:

“Allowing for full public participation, as NEPA requires, is particularly important for projects involving nuclear waste,” the delegation said. “Any proposal to store commercial spent nuclear fuel raises a number of health, safety and environmental issues, including potential impacts on local agriculture and industry, issues related to the transportation of nuclear waste, and disproportionate impacts on Native American communities.”…….https://www.krwg.org/post/60-day-extension-public-comment-period-proposed-nuclear-waste-dump-new-mexico

Nuclear reactor pressure vessel to be shipped by rail to Utah, from Sanonofre

After decades, the heart of a nuclear reactor will finally leave San Onofre    https://www.ocregister.com/2020/04/30/after-decades-the-heart-of-a-nuclear-reactor-will-finally-leave-san-onofre/  

The reactor pressure vessel for Unit 1, the first of three reactors on site, will get a permanent home in Utah, By TERI SFORZA | tsforza@scng.com | Orange County Register, May 1, 2020   The original plan, nearly 20 years ago, was to plop the retired nuclear reactor pressure vessel on a barge and ship it off — via the Panama Canal or all the way around the tip of South America — to a final resting place in South Carolina.But there were strong objections to transporting the huge metal shell that way. After all, atoms had actually been split inside it. And so the giant, but empty, heart of San Onofre Nuclear Generating Station’s Unit 1 was packed away in a huge steel cylinder in 2002. The cylinder was filled with grout for shielding against radiation. It was sealed, and has been stored at the plant ever since.

Now — as serious tear-down work gets under way on Units 2 and 3 — the heart of long-ago-dismantled Unit 1 is finally slated to leave San Onofre forever.

Operator Southern California Edison is preparing to ship Unit 1’s reactor pressure vessel to a licensed disposal facility in Clive, Utah, which is owned by Energy Solutions, one of San Onofre’s decommissioning contractors. It will have company: San Onofre’s retired steam generators were shipped to Clive in 2012.

Though officials can’t get too specific on precisely when or how the vessel will go — for safety reasons — they’ve been preparing a rail spur to haul heavy components off site.

The reactor vessel is considered low-level waste, the least hazardous of the Nuclear Regulatory Commission’s radioactive waste classifications. Contaminated cleaning supplies, used disposable protective clothing and reactor parts are other examples of low-level waste.

How can the crucible for nuclear reactions be low-level waste? The most radioactive parts within it were removed, cut up, and stored with higher-level waste on site, said John Dobken, a spokesman for Edison. What’s left is Cobalt-60, which has a half-life of about five years.

Unit 1 was retired in 1992, and the reactor vessel has been packaged for 18 years, so it has gone through about five half-lives, reducing its radioactivity, Dobken said.The contact dose rate for the vessel package is less than 0.1 millirem an hour, which is 500 times below the Department of Transportation limit for these types of shipments, Edison said in a primer on the move. For comparison, a chest X-ray provides a dose of 10 millirem.

Since this is low-level waste, it was never part of Edison’s contract with the federal government requiring the U.S. Department of Energy to haul away high-level waste by 1998 in exchange for payments into the Nuclear Waste Fund.

The federal government’s paralysis on finding a permanent home for the nation’s high-level nuclear waste is why 40 years’ worth of it remains stuck on site, generating sharp controversy.

While critics have called on Edison to cease decommissioning work at San Onofre during the lock-down, it proceeds with “pandemic protocols” in place, Dobken said. Everyone on site must wear a mask and practice social distancing.

———————————–

By the numbers: The package weighs 770 tons, or more than 1.5 million pounds. Inside is the Unit 1 reactor pressure vessel, pieces of radioactive metal and grout for radiation shielding. It’s a 2-inch-thick carbon steel cylindrical canister with a 3-inch-thick carbon steel liner; top and bottom plates are 3 inches thick. The canister is 38.5 feet long and 15.5 feet in diameter.

Offshore wind is General Electric’s great opportunity, not dodgy Small Nuclear Reactors

GE Power Plays: Wind Might Blow Coal, Gas And Nuclear Away, Seeking Alpha,  Apr. 29, 2020 Keith Williams
Summary

GE offshore wind: massive offshore turbine Haliade-X 12MW looks like a winner.

GE-Hitachi Nuclear Energy may be a receding opportunity.

GE might sell its steam power business and rationalise its fossil fuel interests.

The power and renewables businesses are important in considering investment in GE.

………. Nuclear Small Modular Reactors : GE-Hitachi BWRX-300

There is a lot of talk in the nuclear industry and also in political circles from groups who are opposed to solar PV and wind developments, yet who acknowledge the need for low emissions technologies. The World Nuclear Association (WNA) has an excellent summary of many proposed developments in the area of Small Modular Nuclear Reactors (SMRs). The list of projects is long but many (most) seem to be struggling. A key point from the WNA report is the following : “Licensing is potentially a challenge for SMRs, as design certification, construction and operation licence costs are not necessarily less than for large reactors.” This is a huge red flag for any SMR project.

A second objection is cost of nuclear power versus solar PV/wind plus storage. There is a lot of information about these relative costs, including well into the future. I am not aware of any studies that suggest that any nuclear technology will be able to compete with renewables and storage on price.recent study (December 2019) by the Australian Energy Market Operator (AEMO) and CSIRO concluded that SMR nuclear reactors will generate power costing ~8x that of rooftop or solar PV and wind, with solar and wind costs of power generation being similar. 

……. With Small Modular Reactors the poster child of nuclear power supporters, it is clear that there is a lot riding on this potential saviour for the nuclear industry after Fukushima and recent delays and cost blowouts in the European (especially UK, French and Finnish) nuclear industries.

With current focus on emissions reductions and the climate emergency, this is an excellent time for low emissions technologies. However, the need is now and renewables (solar PV and wind) plus storage (pumped hydro and batteries) are making a lot of progress in addressing the needs. My question is whether the cost structure and long lead times mean that nuclear technology is too expensive and late to play a part.

recent summary of the current state of the nuclear industry as a whole is depressing reading for someone who is enthusiastic about the nuclear industry’s prospects. A lot has to happen in the next decade and SMR technology isn’t ready yet. Is GE investing a lot in a technology that can’t compete with the dramatic advances in solar PV, wind and battery storage?……

GE’s adventures in nuclear developments seem like the kind of speculative play GE could happily fund when it was one of the world’s biggest and most powerful engineering companies. It doesn’t have that status anymore and my take is that it needs to cut its cloth and focus on projects that will have more immediate commercial outcomes. Of course, that is asking for a big rethink about how GE sees itself, but does it really have a choice if it wants to survive?

Offshore wind business

While there is some apprehension in the wind industry, especially in the US and China, as changes in regulations come into force next year, and 2020 has been messed up by COVID-19, there is a long-term future for wind power; offshore wind prospects look huge………

GE Renewable Energy is a major wind turbine supplier, with more than 42,000 of its turbines (mostly onshore) installed. Its role in the wind industry is extensive, from manufacture, digital optimization, operations and maintenance. Its onshore turbines range in size from 1MW to 5MW. GE installed ~50% of onshore turbines in the US last year, a 40% increase compared with the number of onshore turbines it installed in the US in 2018.

The offshore market is still emerging, with turbines substantially bigger than those used onshore. ….. The area that looks to me as if it could become a big winner is in offshore wind turbine developments, ….

A lot of investors have GE in their portfolios and a lot more are probably reflecting on whether GE might once again become a secure safe-haven investment. My biggest issue with GE is that it seems to me it is yet to understand that it is no longer the huge and dominant business that can afford to make big bets that burn a lot of cash. The current SMR nuclear programs in GE seem to be in this category. They have a very low chance of success but require major resources. I’d prefer not to have these distractions in a company I invest in….. https://seekingalpha.com/article/4340805-ge-power-plays-wind-might-blow-coal-gas-and-nuclear-away

Low Oil Prices May Kill Off The Next Nuclear Boom Before It Begins

Low Oil Prices May Kill Off The Next Nuclear Boom Before It Begins, Oil Price, By Alex Kimani – Apr 27, 2020
“…… the third nuclear gold rush could be dead in the water amid low energy prices and stiff public opposition towards a sector that has increasingly fallen out of favour.

Opening up the West

On Thursday, the Nuclear Fuel Working Group (NFWG) made recommendations to the U.S. Administration to open up ~1,500 acres outside the Grand Canyon for uranium production, arguing that the country needs to beef up domestic production to avoid an over-reliance on foreign sources.

The organization has recommended spending $1.5 billion over ten years buying uranium from American producers to create a uranium stockpile that would necessitate buying about 10 million pounds a year.

The working group’s report claims that the United States also needs more uranium for two other purposes:

–  Low-enriched uranium for the production of tritium for nuclear weapons through the 2040s, and

–  Highly enriched uranium to be used as fuel for Navy nuclear reactors through the 2050s

The slow and painful demise of the American uranium mining industry can be chalked up to the fact that the country is not endowed with the most abundant and most accessible uranium deposits, with resources in Canada and Australia boasting significantly higher uranium content and a lower production cost per unit.

American miners have had trouble making a profit from their operations even at the best of times. Consequently, the industry has historically had to rely heavily on government largesse.

During the golden age of American uranium that spanned from 1955-1980, the U.S. government offered fat uranium bonuses in a bid to shore up its stockpiles during the Cold War. These included 10-year price guarantees for certain kinds of ore as well as $10,000 discovery and production bonuses for new sources, which pencils out to nearly $100K in today’s dollars. The incentives set off a mad gold rush in the nation’s vast Western region as every man with a jeep and a Geiger counter set out to make the next significant discovery.

The program was a resounding success: U.S. uranium stockpiles skyrocketed so much that the government stopped paying out the bonuses sometime in the 1960s…….

By 1987, the tables had turned completely, with the country importing nearly 15 million pounds of uranium while domestic production clocked in at just 13 million.

Growing competition weighed heavily on domestic production while the country’s love affair with nuclear energy got its first dose of the harsh reality of nuclear technology thanks to the Three Mile Island nuclear disaster in 1979 as well as the Chernobyl reactor meltdown of 1986 that turned an entire Ukrainian city into a ghost town. Meanwhile, utilities began to grow weary of the time and cost of building reactors, which further depressed demand.

The result: U.S. uranium production had sunk to a 35-year low by the time the last wave of reactors came online in 1990…….

Brief Renaissance

The U.S. uranium industry enjoyed a renaissance in the early 2000s as falling global stockpiles, and booming economies in China and India drove new demand.

Unfortunately, this, too, was not to last as the financial crisis of 2008 destroyed demand, while the Fukushima nuclear disaster of 2011 led to another severe backlash that set off a new round of reactor closures while Germany set to phase out the technology by 2022.

The third nuclear gold rush is starting off on very shaky grounds, too.

First off, the world’s strategic uranium reserves are not in any immediate danger of running out. In 2016, the International Atomic Energy Agency said that the global nuclear fleet has enough stockpiles for 130 years, more than enough for the markets to respond to any shortfalls rapidly as they have done in the past.  …..

But more importantly, trying to open up the west for uranium mining is bound to be met with stiff resistance and widespread public uproar.

For all its setbacks over the years, nuclear power has remained broadly popular in the United States. However, the turning point came in 2016 when the majority of people turned against the technology.

The latest poll last year revealed that American public opinion remains split over nuclear power, with 49 percent of U.S. adults either strongly favor (17 percent) or somewhat favor (32 percent) it in power generation while 49 percent either strongly oppose (21 percent) or somewhat oppose (28 percent) its use……

The funny thing is that Gallup has found that American opinion on nuclear power does not have much to do with radiation or safety concerns; rather, it is driven by prevailing fuel prices.  …..

a 2020 Colorado College Conservation in the West Poll found that 71 percent of voters in the Mountain West and 77 percent of Arizona voters oppose the development of new uranium mines on public lands adjacent to the Grand Canyon. It’s the kind of backlash that no president wants to deal with, whether they are seeking re-election or not. https://oilprice.com/Energy/Energy-General/Low-Oil-Prices-May-Kill-Off-The-Next-Nuclear-Boom-Before-It-Begins.html

Beyond Nuclear opposes Holtec nuclear waste plan: the Nuclear Regulatory Commission is not above the law

Group Plans To Fight Effort To Build Nuclear Waste Dump In New Mexico   https://www.krwg.org/post/group-plans-fight-effort-build-nuclear-waste-dump-new-mexico

By BEYOND NUCLEAR • APR 28, 2020  Commentary: In an astounding ruling on April 23, 2020, the four-member U.S. Nuclear Regulatory Commission (NRC) acknowledged that an application by Holtec International/Eddy-Lea [Counties] Energy Alliance to store a massive quantity of highly radioactive irradiated nuclear fuel in southeastern New Mexico violates federal law – and yet ruled that the unlawful provisions of the license application could be ignored and would not bar approval.

Beyond Nuclear has challenged the NRC’s authority to approve Holtec’s license application because it contemplates that the U.S. Department of Energy (DOE) may become the owner of the irradiated reactor fuel. The federal Nuclear Waste Policy Act (NWPA) prohibits federal ownership of spent fuel, however, unless and until a federal repository for permanent disposal is operating.

The NRC Commissioners acknowledged that Federal law prohibits federally-sponsored storage of irradiated reactor fuel unless and until a repository for permanent disposal is in operation. Nevertheless the NRC threw out Beyond Nuclear’s legal challenge to the project on the ground that Holtec could be depended on not to implement the unlawful provision if the license were granted.

The Commissioners’ decision affirms an earlier ruling by the NRC’s Atomic Safety and Licensing Board that the storage facility may be licensed despite the illegal license terms contemplating federal ownership of the irradiated fuel. The Licensing Board accepted arguments by Holtec and the NRC’s technical staff that the license containing illegal provisions could be approved as long as it also contained a provision that would allow private ownership of the spent fuel.

Mindy Goldstein, a lawyer for Beyond Nuclear, stated, “the NRC’s decision flagrantly violates the federal Administrative Procedure Act (APA), which prohibits an agency from acting contrary to the law as issued by Congress and signed by the President.” Goldstein also stated that “the Commission lacks a legal or logical basis for its rationale that the illegal provisions could be ignored in favor of other provisions that are legal, or that an illegal license could be issued in ‘hopes’ that the law might change in the future. The APA gives the NRC no excuse to ignore the mandates of federal law.”

Diane Curran, also a lawyer for Beyond Nuclear, said the group will pursue a federal court appeal of the NRC decision. “Our claim is simple,” she declared. “The NRC is not above the law.”

Kevin Kamps, radioactive waste specialist for Beyond Nuclear, called the federal Nuclear Waste Policy Act “the public’s best protection against an interim storage facility becoming a de facto permanent, national radioactive waste dump at the surface of the Earth.” According to Kamps, “Congress knew, in passing the NWPA, that the only safe long-term strategy for care of irradiated reactor fuel is to place it in a permanent repository for deep geologic isolation.

Congress acted wisely in refusing to allow nuclear reactor licensees to transfer ownership of their irradiated reactor fuel to the DOE until a repository was up and running.  The carefully crafted Nuclear Waste Policy Act thus protects a state like New Mexico from being railroaded by the powerful nuclear industry, its friends in the federal government, and other states looking to off-load their mountain of forever deadly high-level radioactive waste.”

Kamps added: “A deep geologic repository for permanent disposal should meet a long list of stringent criteria. These include legality, environmental justice, consent-based siting, scientific suitability, mitigation of transport risks, regional equity, intergenerational equity, and non-proliferation, including a ban on reprocessing. This is why a coalition of more than a thousand environmental, environmental justice, and public interest organizations, representing all 50 states, have opposed the Yucca Mountain dump targeted at Western Shoshone Indian land in Nevada for 33 years.”

“On behalf of our members and supporters in New Mexico, and across the country along the road, rail, and waterway routes in most states, that would be used to haul the high risk, high-level radioactive waste out West, we will appeal the NRC Commissioners’ bad ruling to the federal court,” Kamps added.

Beyond Nuclear is a 501(c)(3) nonprofit membership organization. Beyond Nuclear aims to educate and activate the public about the connections between nuclear power and nuclear weapons and the need to abolish both to safeguard our future. Beyond Nuclear advocates for an energy future that is sustainable, benign and democratic. The Beyond Nuclear team works with diverse partners and allies to provide the public, government officials, and the media with the critical information necessary to move humanity toward a world beyond nuclear.

Indian Point nuclear power station’s first step to closure, as one reactor shuts down

Nuclear power plant north of New York City to start shutdown, Daily Journal ,By MARY ESCH Associated Press, Apr 29, 2020 

ALBANY, N.Y. (AP) — With the push of a red button, one of the two operating nuclear reactors at the Indian Point Energy Center along the Hudson River north of New York City will shut down Thursday night as federal regulators consider the plant owner’s proposal to sell it to a company that plans to demolish it by the end of 2033 at a projected cost of $2.3 billion.

The 1,020-megawatt Unit 2 reactor will close for good Thursday and 1,040-megawatt Unit 3 will close in April 2021 as part of a deal reached in January 2017 between Entergy Corp., the state of New York and the environmental group Riverkeeper. The Unit 1 reactor shut down in 1974, 12 years after the plant began operation in the Westchester County town of Buchanan……

Democratic Gov. Andrew Cuomo had long sought the shutdown, saying the plant 24 miles north of Manhattan posed too great a risk to millions of people who live and work nearby. Riverkeeper noted Hudson River fish kills, soil and water contamination, recurrent emergency shutdowns and vulnerability to terrorist attacks. Entergy cited low natural gas prices and increased operating costs as key factors in its decision to close Indian Point and exit the merchant power business.

A year ago, Entergy announced a deal to sell the 240-acre facility to the New Jersey-based decommissioning firm Holtec International, which has submitted a dismantling plan to the Nuclear Regulatory Commission. At a public information session held online last week, NRC representatives said the commission is reviewing Holtec’s financial and technical qualifications, as well as public comments, before approving the license transfer.

According to the NRC, Indian Point will join 13 other nuclear power plants across the United States that have begun the decades-long process of decommissioning, which dismantles a facility to the point that it no longer presents a radioactive danger.

Under the decommissioning process, spent fuel rod assemblies are initially placed in large pools of water where the hot fuel is cooled for at least two years. Then the spent fuel is transferred into giant steel and concrete cylinders that stay at the site unless or until a national nuclear waste storage facility is created……..

A 2017 analysis by the New York Independent System Operator, which runs the state’s electrical grid, concluded that Indian Point’s closure won’t impair the grid’s ability to keep New York City’s lights on.  ……https://www.smdailyjournal.com/news/state/nuclear-power-plant-north-of-new-york-city-to-start-shutdown/article_62453a0b-19d7-5baf-9dfc-a7db2d15710f.html

Do-it-yourself radiation monitoring

The next step in do-it-yourself radiation monitoring  https://thebulletin.org/2020/04/the-next-step-in-do-it-yourself-radiation-monitoring/#

By Dahyun Kang, April 28, 2020  Watching the HBO drama Chernobyl about the nuclear disaster that occurred in April 1986 gave me a whole new perspective on how destructive radioactive particles can be. One scene depicted local men and women fearfully looking toward the nuclear site, a dim red glow against the night sky. Highly radioactive cesium-137-contaminated dust fell like snow on children running in the streets. Plant workers and firefighters died gruesomely after exposure to acute radiation doses unleashed by the debris that exploded from the nuclear reactor. No one knew what to do because Soviet bureaucrats delayed accident announcements and evacuation orders.

The lack of information about radiation levels meant that people were exposed to radiation for a longer duration than if they had received timely warnings. The Chernobyl drama not only helped me realize the disastrous consequences and hazards of radiation, but also inspired me to create a radiation estimator that could provide estimations of environmental radiation levels in places where there are no stationed detectors.

A focus on Fukushima. To develop my estimator, I focused on the Fukushima region in Japan. I chose this area because of the nuclear disaster there in March 2011, when three nuclear power plant cores melted down and released radionuclides into the atmosphere. The Japanese government chose this region to hold a couple of events that are part of the 2020 Tokyo Summer Olympics and Paralympics, branded as the “Reconstruction Olympics.”

The environmental group Greenpeace has raised concerns about whether people attending these Olympic events—which have now been postponed until 2021—could be exposed to lingering radiation. In a report published last month, Greenpeace claimed measurements taken by a survey team detected radioactive hotspots at the Fukushima Azuma Baseball Stadium near Fukushima City, in the area around the city’s central station, and at the J-Village sports complex where the Olympic torch relay will start. According to Greenpeace, the highest measurement at J-Village on October 26, 2019, was 71 microsieverts per hour close to the ground, a reading more than 1,750 times higher than pre-2011 background levels. The forested mountains covering roughly 70 percent of the Fukushima prefecture cannot be decontaminated and therefore pose a recontamination risk to areas when heavy rainfall or typhoons mobilize radionuclides, which Greenpeace says happened during two intense typhoons in 2019.

Japan’s Shinzo Abe administration plans to host the Olympics baseball and softball games at the Azuma stadium, approximately 80 kilometers from the Fukushima Daiichi nuclear power plant site where the nuclear accident occurred. J-Village, where the torch relay will begin, is located about 20 kilometers south of Fukushima Daiichi.

How I built my radiation estimator. The nonprofit organization Safecast, which collects radiation readings taken by volunteers and makes them publicly available at no charge, provides data for a number of locations worldwide—particularly in Japan, where the monitoring network began as a response to the Fukushima disaster. Using the Safecast website, I collected data from the Fukushima prefecture. With the help of mathematical software called Mathematica, I then developed a mathematical equation that takes the Safecast Fukushima data and provides estimates of radiation values at any other location in Fukushima. With the help of a relative who works as a coding programmer, I also created a Radiation Estimation website that uses the mathematical equation to estimate radiation values, in microsieverts per hour, for any latitude and longitude entered by a user.

For example, if the user enters the latitude and longitude of the Azuma stadium, the equation gives an estimate of 0.103 microsieverts per hour. According to the International Commission on Radiological Protection, anything less than 0.23 microsieverts per hour is considered a safe dose, based on the recommended public dose limit of 1 millisievert per year (1 millisievert is equivalent to 1,000 microsieverts).

Future efforts. Currently, my radiation estimator inevitably contains some degree of uncertainty due to limited available data from the Fukushima prefecture, which covers about 13,700 square kilometers. The estimates would be more precise and could be applied beyond Fukushima if there were more disclosed data available to reference.

What about the radiation levels in my own city and others in the United States? Unfortunately, I was unable to find enough open radiation data available to make a good estimate. The US Environmental Protection Agency runs a nationwide environmental radiation monitoring system, RadNet, which has 140 radiation air monitors spread across 50 states, mostly in the heart of big cities. Although these monitors run 24/7, collecting near-real-time measurements of gamma radiation, the number and locations of the monitors are inadequate to cover all of the United States.

There are 96 US nuclear power reactors in operation. Who can assure the American public that no nuclear catastrophe on the scale of Chernobyl or Fukushima will occur in the United States? It is natural for the public to be worried and to insist that the US government install more radiation monitors near reactors and the surrounding populated areas to protect the public. Information collected by the monitors should also be disclosed to the public.

Once sufficient environmental radiation data are available, my radiation estimator would be applicable in my own city and others in America as well. I hope to raise awareness of environmental radiation and offer people information about what kind of environment they are living in. Since my radiation estimator is only a first step in that direction, I hope that someone with more expertise can build upon my idea to create a more precise tool that provides information about environmental radiation anywhere on the globe.
