Fukushima reactors molten fuel cores – where are they? Robots might find them

exclamation-Robots To Investigate Fukushima N-reactors http://www.bernama.com.my/bernama/v7/wn/newsworld.php?id=1036936 TOKYO, May 9 (Bernama) — Tokyo Electric Power Co. (TEPCO) plans to use robots for investigating the inside of reactor containment vessels at its stricken Fukushima No. 1 nuclear power plant.

The investigation is expected to take place as early as in the fiscal second half that begins in October, sources were quoted as saying by Japan’s Jiji Press news agency.

Internal conditions of the containment vessels at the plant’s No. 1 to 3 reactors remain unknown.

If the robots — made by Hitachi Ltd. and others — are able to identify where melted nuclear fuel is located, this would lead to progress in work to decommission the plant damaged in the March 2011 earthquake and tsunami.

But it is unclear how much information can be obtained by the robots due to high radiation levels and steams inside the vessels.

TEPCO said the investigation is aimed at assessing temperatures and radiation levels inside the vessels.

The government plans to start removing melted fuel in 2020.

New Mexico nuclear waste facility might close for several years

Video: WIPP nuclear site may close for several years — Explosion in multiple drums suspected — “Very much a cause for concern” — Top official gives ‘fiery speech’ calling for public to be told what has happened — DOE refuses to name source of nuclear waste http://enenews.com/video-wipp-nuclear-site-may-close-for-several-years-explosion-in-multiple-drums-suspected-very-much-a-cause-for-concern-top-official-gives-fiery-speech-calling-for-public-to-be-told


Albuquerque Journal,May 9, 2014: The head of the recovery effort at the federal government’s nuclear waste repository in southern New Mexico said Thursday it could be up to three years before full operations resume at the underground facility. […] the focus has turned to a set of waste drums that came from Los Alamos National Laboratory. Officials at the meeting reiterated the possibility that there may have been a chemical reaction inside the drums. […] New Mexico Environment Secretary Ryan Flynn said the theory of a chemical reaction is based on limited knowledge, and he urged officials during the meeting not to withhold any information. Flynn said he’s concerned the public will lose faith […] “We need to know what happened. We absolutely need to know,” he said. […] Los Alamos is under a tight deadline to get the plutonium-contaminated waste off its northern New Mexico campus before wildfire season peaks. […] Lab Director Charlie McMillan said Thursday during a news conference in Albuquerque that the recent developments “are very much a cause for concern.”

Carlsbad Current Argus,May 9, 2014: […] community leaders in Carlsbad and New Mexico government officials have begun to reveal their irritations. New Mexico Environment Department Secretary Ryan Flynn capped the weekly WIPP town hall with a fiery speech [and] called for the immediate closure of all waste panels except Panel 7 at WIPP, as well as complete public transparency. […] after investigators narrowed the likely cause to the waste makeup from LANL. Nuclear Waste Partnership Recovery Manager Jim Blankenhorn announced on Thursday that WIPP officials believe the radiation leak was likely caused by nuclear waste that contained nitrate salt which gave off some sort of a chemical reaction. The waste with nitrate salt matched waste stored in drums that originated from three separate waste streams: two of the waste streams originated from LANL and the source of the other was unknown because DOE and NWP refused to name the source.

Solar panels are back on the White House

Flag-USAWhite House solar panels power up Barack Obama unveils new solar expansion plans as officials confirm White House panels are now operational http://www.theguardian.com/environment/2014/may/09/obama-solar-power-initiatives-california  Suzanne Goldenberg, US environment correspondent  theguardian.com, Friday 9 May 2014 Barack Obama will on Friday unveil several new initiatives intended to expand the deployment of solar power on Friday, as officials confirmed that a set of solar panels on the roof of the White House was now operational.

Obama will – once again – bypass a deadlocked Congress and use his executive authority to announce $2bn funding for energy-saving measures at federal government buildings, as well as new financing and training programmes for solar installations.

The announcements, to be made on a trip to California, cap a climate-focused week at the White House, following the release of an authoritative report on the growing threat posed by heat waves, severe downpours and sea-level rise.

Inside the White House: Solar Panels

White House officials told a conference call with reporters the initiatives were intended to add momentum to the solar industry, which has seen rapid expansion over the last two years.

“We are going to be doing everything we can, with the tools that we have to move forward,” said Dan Utech, special assistant to the president on energy and climate change.

In a largely symbolic move, the White House began installing a small set of solar panels on the roof last summer. The fit was now complete, officials said, releasing a video in which the panels were shown being installed. “The size of the array we established here is the typical size for the average American house, ” said James Doherty, the White House usher. Security concerns had prevented the whole roof being covered, he said.

Almost cetain hat European Commission will find UK’s Hinkley nuclear funding illegal

justiceflag-EUEuropean Commission likely to find Hinkley aid illegal: Europe London (Platts)–8May2014 The European Commission will almost certainly find that EDF Energy’s funding mechanism for the construction of the Hinkley Point C nuclear unit in the UK is illegal state aid, an Austrian law professor told Platts.

Franz Leidenmuhler, who specializes in EU state aid cases and European competition law, said in an email that he believed “a rejection is nearly unavoidable. The Statement of the Commission in its first findings of December 18, 2013 is too clear. I do not think that some conditions could change that clear result.”

The new Hinkley unit will be built based on a funding model in which the UK government guarantees a floor price for future power sales. This floor price, known as a “strike price,” is the reference price below which EDF would receive UK government financial support and above which EDF would pay back money, effectively a guaranteed price for the power.

The strike price has been set at GBP92.50/MWh ($156.04) if the proposed new EPR there is the only new nuclear unit built by EDF Energy. The strike price would be GBP89.50 for both units if EDF is able to use the same EPR design to build another reactor at Sizewell C.

The support, known as contracts for difference, will be delivered through investment contracts designed to provide the most efficient long-term support for all forms of low-carbon generation. If the EC were to find the aid illegal, it is unclear whether EDF would go forward with the construction of the new reactor.

In a speech delivered at an industry conference last month, Leidenmuhler said that “in my opinion, the result has to be that this CfD is illegal state aid. Contrary to renewables, there is no exception for nuclear power in the general block exemption regulation, so that, as a result, CfDs in the field of nuclear power are not compatible with EU law.”…..

The categories of aid that are allowed under the block exemption include the areas of small- and medium-sized businesses, research, innovation, regional development, training, employment of disabled and disadvantaged workers, risk capital and environmental protection.

Leidenmuhler indicated he believed EDF’s funding mechanism for Hinkley Point C did not meet these criteria to be granted an exemption for state aid…….

The issue of a potential precedent being set was a point emphasized indirectly by Leidenmuhler in his presentation, when he cited the recent decision by the Czech government not to offer aid guarantees for the construction of a new nuclear unit at Temelin that would be similar to the guarantees offered by the UK government for Hinkley Point C.

“The decision of the Czech Government three weeks ago not to give such price guarantees in the case of Temelin is not only an economically reasonable step, but also legally required from the view of EU State aid law,” Leidenmuhler said.

Depleted uranium pollution of Hawaii by Pentagon’s dirty bombing

depleted-uraniumThe Pentagon’s Dirty Bombers: Depleted Uranium in the USA, Aletho News By David Lindorff – 10/26/2009 The Nuclear Regulator Commission is considering an application by the US Army for a permit to have depleted uranium at its Pohakuloa Training Area, a vast stretch of flat land in what’s called the “saddle” between the sacred mountains of Mauna Loa and Mauna Kea on Hawaii’s Big Island, and at the Schofield Barracks on the island of Oahu. In fact, what the Army is asking for is a permit to leave in place the DU left over from years of test firing of M101 mortar “spotting rounds,” that each contained close to half a pound of depleted uranium (DU). The Army, which originally denied that any DU weapons had been used at either location, now says that as many as 2000 rounds of M101 DU mortars might have been fired at Pohakuloa alone.

But that’s only a small part of the story.

The Army is actually seeking a master permit from the NRC to cover all the sites where it has fired DU weapons, including penetrator shells that, unlike the M101, are designed to hit targets and burn on impact, turning the DU in the warhead into a fine dust of uranium oxide. Hearings on this proposal were held in Hawaii on Aug. 26 and 27.

Uranium particles, whether pure uranium or in an oxidized form, are alpha emitters, and can be highly carcinogenic and mutagenic if ingested or inhaled, since they can lodge in one part of the body—the kidney or lung or gonad, for example—and then irradiate surrounding cells with large, destructive alpha particles (actually helium atoms), until some gene is compromised and a cell become malignant.

Among the sites identified by the NRC as being contaminated with DU are:

Ft. Hood, TX
Ft. Benning, GA
Ft. Campbell, KY
Ft. Knox, KY
Ft. Lewis, WA
Ft. Riley, KS
Aberdeen Proving Grounds, MD
Ft. Dix, NJ
Makua Military Reservation, HI

Other locations identified as having DU weapons contamination are:

China Lake Air Warfare Center, CA
Eglin AFB, Florida,
Nellis AFB, NV
Davis-Monthan AFB
Kirtland AFB, NM
White Sands Missile Range, NM
Ethan Allen Firing Range, VT
New Mexico Institute of Mining and Technology

An application for a 99-year permit to test DU weapons at the NM Inst. Of Mining and Technology claimed that that site’s test area was “so contaminated with DU… as to preclude any other use”!

DU weapons have also been used by the Navy at Vieques Island off Puerto Rico (the Navy claimed it was a “mistake.”)………. http://alethonews.wordpress.com/2014/05/09/the-pentagons-dirty-bombers-depleted-uranium-in-the-usa/

Fukushima groundwater radioactive contamination getting worse, but not properly measured

water-radiationOngoing Impact of Wastewater from Fukushima Nuclear Power Station
Hydro International, By Shunji Murai Professor Emeritus, University of Tokyo, Japan08/05/2014
Three years on from the Great East Japan Earthquake and Tsunami of 11 March 2011, air contamination is decreasing and is now concentrated in a limited area. Land contamination has also decreased through decontamination processes. However, despite all the efforts by Tokyo Electric Power Company (TEPCO) and the Japanese government, water contamination in surface and ground water is getting worse, simply because there are no effective countermeasures. …….
Even though the wastewater issue is taken seriously by Japanese people as well as people worldwide, the real status of the effect of the contamination is still unknown because neutral third-party organisations have no access to within a 20km radius of Fukushima NPS. The author has tried to make clear what the status of the wastewater issue is by using various sources including a Fishermen Union’s report, which appears to be more reliable than the government report or the report by TEPCO.  http://www.hydro-international.com/news/id6913-Ongoing_Impact_of_Wastewater_from_Fukushima_Nuclear_Power_Station.html

New research shows that TEPCO underestimated radioactive cesium released from Fukushima

Cesium-137Radioactive cesium levels at Fukushima higher than TEPCO claims, Voice of Russia, 6 May 14 A new study conducted by Japanese researchers revealed that cumulative amount of radioactive cesium at the disaster-hit Fukushima nuclear power plant is nearly 1,5 times higher than previous estimates of the Tokyo Electric Power Co. (TEPCO), RIA Novosti reports. According to the research, between 17.500 and 20.500 terabecquerels of radioactive cesium-137 was released into the atmosphere from the Fukushima reactors against less than 13.600 terabecquerels declared by the plant operator TEPCO.

Earlier in April Japan’s Ministry of Economy, Trade and Industry issued a report that showed significant drop of radiation levels in areas surrounding Fukushima to under 20 millisieverts per year. These figures, however, exceed the long-term target of Japanese government of 1 millisievert per year.

Sweden turning against nuclear power

Swedes are becoming increasingly skeptical of nuclear power with a new survey showing 50 percent of respondents want the controversial power source phased out.

The report from the SOM Institute at the University of Gothenburg found support falling for nuclear power since a meltdown at Japanese power plant. With other European nations moveing away from nuclear power, Swedes are also growing leery.

“The fact that Germany, Switzerland, Italy and several other countries have begun to phase out nuclear power, it’s likely that nowadays it might happen in Sweden, too,” Sören Holmberg, a political science professor at Gothenburg University, told Swedish Radio News.

Before the nuclear accident at Fukushima in Japan, Swedes were generally positive toward building new reactors with 44 percent supporting the measure and 39 percent opposing it. After the disaster in 2011, 44 percent said they were against nuclear power and now half of respondents are anti-nuclear.

As before, support for new nuclear plants is strongest on the right of the political spectrum and the greatest resistance is from the left. Men and white collar workers are also more positive than women and laborers.

EPA acts to protect public from radioactive danger from thorium at Ridgewood Queens, New York

ThoriumEPA Adds Radiation Site in Ridgewood Queens, New York to the Superfund List EPA 05/08/2014  Contact Information: Elias Rodriguez, (212) 637-3664rodriguez.elias@epa.gov

(New York, N.Y.) The U.S. Environmental Protection Agency has added the Wolff-Alport Chemical Company site in the Ridgewood section of Queens, New York to the federal Superfund list of hazardous waste sites. The soil and nearby sewers were contaminated by radioactive material from past industrial activities at the site. Testing indicates that there is no immediate threat to nearby residents, employees or customers of businesses in the affected area along Irving and Cooper Avenues. Since exposure to the radioactive contamination may pose a threat to health in the long-term, in December 2013, the EPA took action to reduce people’s potential exposure to the radiation and address the potential health risks from the site. 

The now-defunct Wolff-Alport Chemical Company operated from 1920 until 1954, processing imported monazite sand and extracting rare earth metals. Monazite contains approximately 6% to 8% thorium, which is radioactive. Radiation can increase a person’s risk of developing cancer such as cancer of the lung or pancreas.

“By placing the Wolff-Alport Chemical Company site on the Superfund list, the EPA can address the contamination to protect people’s health in the long-term,” said Judith A. Enck, EPA Regional Administrator. he Wolff-Alport Chemical Company site includes 1125 to 1139 Irving Avenue and 1514 Cooper Avenue in Ridgewood, on the border of Brooklyn and Queens. During its years of operation, the facility occupied three structures and two yard areas at 1127 Irving Avenue. The company did not operate out of 1125 Irving Avenue or 1514 Cooper Avenue, but those properties were affected by the contamination. Today the site includes six parcels of land with five buildings that house several small businesses, office space and warehouses. Until 1947, the company disposed of thorium waste in the sewer and on its property. The U.S. Atomic Energy Commission ordered the company to stop those practices in 1947.

The EPA assisted New York State and New York City in conducting radiological surveys in the area. These surveys identified waste material and radioactivity throughout the property, beneath adjacent public sidewalks and streets and in nearby sewers above levels expected to be found in a comparable urban area. The EPA, the Agency for Toxic Substances and Disease Registry, the New York City Department of Environmental Protection, the New York City Department of Health and Mental Hygiene, the New York State Department of Environmental Conservation and the New York State Department of Health are working together to reduce potential long-term exposure to radiation from the site.

Beginning in August 2012, the EPA took samples to assess the site and determine what immediate cleanup work would be necessary. The EPA used the results of this sampling to take steps to protect people from exposure in the short-term. At Intermediate School 384, radioactive gas was coming from a hole in an unoccupied storage area. The hole was sealed with concrete and follow-up sampling results showed levels below the action level established by the technical experts. At the Terra Nova Construction Company, the EPA installed a mitigation system that reduced radiation levels to below the action level. 

Additional EPA actions included:……….To learn more about the Wolff-Alport site, please visit:http://www.epa.gov/region02/waste/wolff/index.html.http://yosemite.epa.gov/opa/admpress.nsf/0/609e310b78c3ef7a85257cd20055a13a?OpenDocument

The real lessons of Chernobyl and Fukushima

Debating the Merits of Nuclear Power CATHERINE THOMASSON NYT  MAY 8, 2014  Re “The Right Lessons From Chernobyl” (editorial, May 2):

The danger posed by nuclear power goes far beyond the catastrophic accidents that have occurred at Chernobyl and Fukushima. As the nuclear weapon programs of North Korea, Pakistan, Israel, India and perhaps Iran have shown, civilian nuclear power programs are inextricably linked with the technology needed to develop nuclear weapons. 

renewables-not-nukes

We cannot promote nuclear power as a source of electricity and also expect to prevent nuclear weapon proliferation, a development that poses as great a threat to humanity as global warming.Furthermore, nuclear power is not an inexpensive bridge to an energy system based on renewable sources.

It competes for resources with renewables, diverting money from the very technologies we need to promote. Numerous studies provide blueprints for replacing fossil fuels with renewable energy sources more cheaply and quickly than nuclear power can.

It is time to abandon the myth of the peaceful atom and focus on building a renewable energy system that meets the needs of all people.

Quebec’s moratorium on uranium minng extended for another year

flag-canadaStudy on impacts of uranium mining to extend Quebec moratorium another year mining.comCecilia Jamasmie | May 9, 2014 A group of doctors, environmental groups and First Nations leaders gathered in Montreal Thursday to urge Quebec’s new premier to keep the moratorium on uranium mining until the risks and effects of these kinds of operations on nearby communities have been thoroughly studied.

The suspension of uranium mining in the province came in effect in April last year, making Quebec the third Canadian jurisdiction, after Nova Scotia and British Columbia, to halt exploration and development of these kinds of mines.

The Bureau d’audiences publiques sur l’environnement (BAPE), the province’s environmental watchdog, is currently beginning a yearlong study on the matter, which will be carried out in three phases.

The results of this consultation could be critical for the future of mining in the east-central province, which has been losing its allure to investors in the last few years.

Mining investments in Quebec dropped significantly more than expected last year, plunging about 37% from a record year in 2012, and marking the first annual drop in a decade. The jurisdiction has also fallen in the famous index of mining destinations put together every year by the Fraser Institute, an independent think-tank: From being the No.1 desired place to invest in mining from 2007 to 2010, it barely reached the 11th place out of 96 jurisdictions last year……..http://www.mining.com/study-on-impacts-of-uranium-mining-may-extend-moratorium-indefinitely-report-87731-23280/

The Pentagon in denial about the harmful effects of depleted uranium

depleted-uraniumThe Pentagon’s Dirty Bombers: Depleted Uranium in the USA, Aletho News By David Lindorff – 10/26/2009 “……The Pentagon continues a long history of claiming that DU–which is the uranium that is left after the fissionable isotope U-235 is removed to make nuclear fuel and bombs–is not dangerous, although this official stance is belied by the warnings it has given to its troops (though not to civilians in battle zones), to stay well clear of tanks and other equipment destroyed by US tanks, which used DU weapons as the ordnance of choice in both the Gulf War and the current Iraq War. During both wars, DU ammunition was used by Army and Marine tanks, by the Bradley Fighting Vehicle, the A-10 ground support jet, the Marine Harrier jet, and specially equipped F16 fighter jets. The Navy also switched from DU ammunition to tungsten ammunition in its Phalanx anti-missile ship defense system because of health and environmental concerns with the DU ammo.

In both wars, a high percentage of troops have returned with many physical ailments–auto-immune problems, cancers, and later, birth defects in offspring–which have been referred to as Gulf War and now Iraq War Syndrome. As many as a quarter of returning vets from the Gulf War have reported strange illnesses and cancers and the numbers are rising for Iraq War vets. As well, statistics from the National Institutes of Health show that counties hosting bases and test facilities where DU has been uses also show high cancer rates. This is certainly true for Hawaii’s Big Island, which has the highest cancer rates for the Hawaiian archipelago. Meanwhile, the lung cancer rate for the Ft. Knox area is 105-127 per 100,000 for the 2001-2005 period, high by state and national standards. The rate is among the highest in the state of Washington for Pierce County, where Ft. Lewis is located.

The Pentagon denies that it uses depleted uranium in bombs, missiles and cruise missile warheads, but military personnel have reported their use in all three delivery systems, and reports exist of DU bunker-buster bombs, DU-tipped penetrator warheads on Tomahawk cruise missiles and on some air-to-ground missiles.

It’s a good bet that all US munitions containing DU have been widely tested at various US military bases and testing grounds.

The bottom line is that at the same time that US government is continuing to warn about the danger of terrorists acquiring the materials to make a “dirty” bomb that could spread radioactive material in the US, the US military has for years been doing exactly that, and continues to do so, with no intention to clean up its messes, many of which are allowing depleted uranium to percolate into ground water or flow down streams to more populated areas.

Of course, it could have been worse. The M101 mortar that litters Pohakuloa was actually designed as a range-finder for the Davy Crocket mortar, which back in the late 1950s and the 1960s, and up until 1971 was designed to allow infantry troops to fire a small “tactical” nuclear mortar shell at targets just one to two miles distant. Some 700 of these “little nukes”, that had a power of “just” several kilotons or less, were made and actually made their way into the arsenals of troops in Europe and elsewhere during the Cold War. Fortunately there are no reports of any of them having been fired off at any of the military’s firing ranges–especially given that their radiation effect radius was larger than their firing range, meaning that launching one was an automatic suicide mission.

(Actually firing it would have been suicide.)

Then again, the Pentagon doesn’t exactly have a sterling record about telling the truth where nuclear weapons and DU weapons are concerned. (You start to notice as you look into this stuff that with uranium weapons, the military’s attitude towards troop safety is not a whole lot better than its attitude towards the people at the downrange end of the line.)

Nor is the NRC to be relied on to protect the American public. As an administrative judge wrote in a ruling on a case involving DU contamination at Jefferson Proving Ground in Indiana, the NRC exhibited a “more than casual attitude with regard to decommissioning of sites on which radioactive materials remain as a potential threat to public health and safety and to the environment.”

In another case, involving cleanup of the ShieldAlloy Metallurgical Corp.’s site in Newfield, NJ, where DU weapons were made, a judge said, “at the very least, the (NRC) staff has countenanced…a situation that will leave the citizens in the area surrounding the activity site in doubt for close to two decades regarding what measures will ultimately be taken for their protection.” http://alethonews.wordpress.com/2014/05/09/the-pentagons-dirty-bombers-depleted-uranium-in-the-usa/

US Senators oppose changes that would weaken nuclear safety regulations

safety-symbol-SmFlag-USASenators oppose changes to nuclear plant emergency regulations  Relaxed alerts sought for closed Kewaunee plant postcrescent.com 8 May 14 Richard Ryman CARLTON — Dominion Resources Inc., owner of Kewaunee Power Station, wants to reduce the level of emergency response at the closed nuclear plant, such as the Nuclear Regulatory Commission approved at other reactors being decommissioned.

But five U.S. senators are challenging the NRC’s approval of such requests. In a recent letter to the commission, they pointed out that the NRC granted exemptions for each of the 10 requests made. Their concern is for spent nuclear fuel, which can be stored in water pools or dry casks.

Kewaunee spokesman Mark Kanz said Dominion requested exemptions for evacuation zones and siren alerts………..

— Dominion shut down Kewaunee Power Station for decommissioning one year ago May 7. The fuel in the reactors was removed to the spent fuel pool within the week. The fuel rods in the pool, which is inside the plant, are scheduled to be placed in dry-cask storage outside the reactor building in 2016.

They could remain there for 60 years, the amount of time Dominion is allowed to decommission the plant, or longer. The federal government has failed provided a national spent fuel repository as required by law and there is no indication when one will be created………

The senators who wrote to the NRC said National Academy of Sciences and NRC studies determined that draining of a spent nuclear fuel pool can lead to fires, large radioactive releases and widespread contamination. They said emergency protection zones, which can extend up to 50 miles from a reactor, should be maintained.

The senators include Edward Markey of Massachusetts, Barbara Boxer of California, Benard Sanders of Vermont, Patrick Leahy of Vermont and Kirsten Gillibrand of New York. All are Democrats except Sanders, who is independent but votes with Democrats on most issues.

They said exemptions are under review for four nuclear plants, including Kewaunee, Crystal River in Florida, San Onofre in California and Vermont Yankee in Vermont. They cited both the Fukushima, Japan, nuclear incident and the potential for terrorist attacks as reasons for refusing the exemptions……..http://www.postcrescent.com/article/20140508/APC03/305080514/Senators-oppose-changes-nuclear-plant-emergency-regulations
