Nuking a Hurricane Would Probably Just Create a Slightly Bigger, Radioactive Hurricane

Nuking a Hurricane Would Probably Just Create a Slightly Bigger, Radioactive Hurricane  https://www.livescience.com/trump-hurricane-nuclear-bomb.html  By Rafi Letzter 26 Aug 19, o Planet Earth 

Has Trump been reading old Live Science articles about nuking hurricanes? And if not, should he be?

President Donald Trump wants to nuke hurricanes into submission before they reach the Atlantic coastline, according to a bizarre article published yesterday (Aug. 25) on Axios. “Why can’t we do that?” he reportedly asked. This raises an important question: Has Trump been reading old Live Science articles? And if not, should he be?

Live Science answered this very question in a 2012 article.

“The theory goes that the energy released by a nuclear bomb detonated just above and ahead of the eye of a storm would heat the cooler air there, disrupting the storm’s convection current,” Rachel Kaufman wrote at the time. “Unfortunately, this idea, which has been around in some form since the 1960s, wouldn’t work.”

The problem is the energy involved, Kaufman reported, citing writing by Chris Landsea, a former National Oceanic and Atmospheric Administration research meteorologist.

A hurricane is essentially a powerful, super-efficient country-size engine for pulling heat out of the ocean and releasing it into the atmosphere. As a hurricane’s low-pressure system moves over warm water, that water evaporates and then condenses as droplets in the atmosphere. As the water condenses, it releases the heat it’s carrying into the surrounding air. About 1% of that heat energy gets converted into wind; the rest sticks around as ambient warmth, according to the article.

A hurricane can release 50 terawatts of heat energy at any given moment — a significantly greater output than the entire power system, and comparable to a 10-megaton nuclear bomb detonating every 20 minutes. Trying to stop a hurricane with a nuke would be “about as effective as trying to stop a speeding Buick with a feather,” Kaufman wrote, and might even add energy to the storm

Stopping a smaller tropical depression with a nuke might be more realistic, but there are just too many of them and no good way to tell which will develop into powerful, landfalling hurricanes.

“Finally, whether the bomb would have a minor positive effect, a negative effect, or none at all on the storm’s convection cycle, one thing is for sure: It would create a radioactive hurricane, which would be even worse than a normal one. The fallout would ride Trade Winds to land — arguably a worse outcome than a landfalling hurricane,” Kaufman wrote.

The best way to avoid the destruction of a hurricane, remains a boring one: prepare. In case that’s the route you want to go, how to prepare for a hurricane.

Dismay at safety risks of restarting Hunterston Nuclear Reactor 4

Largs and Millport Weekly News 19th Aug 2019 A SERIES of safety failure at Hunterston could have had ‘serious
consequences’ if the reactors had been in full operation, it was claimed
this week. The Nuclear Free Local Authorities group, which is made up of
councillors around the UK concerned about nuclear power, described the
incidents as ‘notable’. The incident which prevented cooling gas from being
circulated around a reactor was highlighted by the group as ‘a real
concern’. However the nuclear regulators described the incident as ‘minor’
as both incidents happened when both reactors were offline. n relation to
the incident, a spokesperson for Nuclear Free Local Authorities said:
“Whilst there were no radiological consequence from them, this is largely
due to the reactors not being in operation. “A loss of cooling is of real
concern as the consequences of such an eventuality when the reactors are in
full operation could have been extremely serious.”

https://www.largsandmillportnews.com/news/17833610.anger-series-safety-failures-hunterston/

The Nuclear Free Local Authorities (NFLA) is disappointed with the decision
of the Office for Nuclear Regulation (ONR) to permit resumption of
electricity generation at Reactor 4 in the EDF-owned Hunterston site in
North Ayrshire. NFLA believes the age, the amount of keyway root cracks in
both Reactors 3 and 4, and the precautionary principle should have been
considered in the reactors not being reopened for generation.

UK’s nuclear regulator allows EDF to restart Hunterston B nuclear reactor, despite cracks

Nuclear regulator permits restarting of reactor 4 at Hunterston B

EDF Energy is expected to restart reactor a year after it was shut down over safety concerns, Guardian, Jillian Ambrose. 21 Aug 19,  Britain’s nuclear watchdog has agreed to allow one of the country’s oldest nuclear reactors to restart, one year after it was shut down to investigate cracks in its graphite core.

EDF Energy is expected to restart reactor 4 at its 40-year-old Hunterston B nuclear plant on the Firth of Clyde in North Ayrshire within weeks after the Office for Nuclear Regulation (ONR) said the plant was safe.

The regulator will allow the reactor to run for four months after proving that the reactor cores can still fulfil their fundamental safety requirements, despite the cracks in its graphite bricks……..

The reactor was shut down last March after investigators discovered more than expected cracks in the graphite core of reactor 4 and reactor 3 at the Scottish nuclear plant. Its application to restart reactor 3, which was found to have more than 350 hairline cracks in its graphite core, is still pending. ……..

The French-owned energy company owns and operates all of the UK’s existing nuclear power plants, which provide about a fifth of the UK’s electricity. It is hoping to extend the reactors’ expected running lives and build new nuclear plants at the Hinkley Point C and Sizewell B nuclear sites.

The company said in 2016 it would extend the lives of its Heysham 1 and Hartlepool nuclear plants, which were due to close this year but will continue to run until 2024. The closure dates of the Heysham 2 and Torness nuclear plants will both be delayed by seven years to 2030.

EDF Energy hopes to run the Hunterston nuclear plant until 2023. https://www.theguardian.com/business/2019/aug/20/edf-nuclear-reactor-restarting-hunterston-b

USA lost unexploded nuclear bomb in Japanese waters

World War 3: Unexploded US nuclear weapon hiding beneath Japanese waters ‘covered up’  https://www.express.co.uk/news/world/1166479/world-war-3-nuclear-bomb-japan-philippine-sea-us-soviet-union-cold-war-sptWORLD WAR 3 could have erupted after the United States Navy accidentally dropped a nuclear bomb in Japanese waters – and it is still there today. by CALLUM HOARE, Aug 18, 2019. On December 5, 1965, just three years after the Cuban Missile Crisis pushed Cold War tensions to the limits, the US made a monumental mistake during a training exercise. A United States Navy Douglas A-4E Skyhawk attack aircraft fell off the side of aircraft carrier USS Ticonderoga while sailing through the Philippine Sea. The pilot, Lieutenant Douglas M Webster, the plane, and the B43 nuclear bomb on board all fell into the water, 68 miles from the coast of Kikai Island, Japan.

However, it was not until 1989 that the Pentagon admitted the loss of a one-megaton hydrogen bomb.

The revelation inspired a diplomatic inquiry from Japan, however, neither the weapon, or the pilot, was ever recovered.The incident, the most serious involving nuclear weapons in the Navy’s history, showed that US warships carried atomic weapons into Japanese ports in violation of policy, according to researchers.

Japanese law banned ships carrying nuclear weapons from sailing in its territorial waters or calling on its ports following the terrible Hiroshima and Nagasaki incidents.

However, the US warship routinely docked in Japan.

William M. Arkin of the liberal Institute for Policy Studies claimed in 1989: “For 24 years, the US Navy has covered up the most politically sensitive accident that has ever taken place.

“The Navy kept the true details of this accident a secret not only because it demonstrates their disregard for the treaty stipulations of foreign governments but because of the questions it raises about nuclear weapons aboard ships in Vietnam.”

The event was highly sensitive, with Japan being the only country to ever be attacked with nuclear weapons at the end of World War 2.

On September 8, 1951, 49 nations drew a line under the devastating event and signed the Treaty of San Francisco – also known as the Treaty of Peace with Japan.

The document officially ended US-led occupation of Japan and marked the start of re-establishing relations with the allied powers.

Meanwhile, In 1965, the US was arguably at the height of tensions with the Soviet Union.

Not only did the accident threaten to spoil already tenuous relations with Japan, but it would have also have given the USSR an excuse to start a nuclear war.

Despite the worrying claims, the US Navy confirmed inn 1989 that the waters were too deep for the weapon to pose a threat.

Worryingly though, it would not be the last of the nuclear gaffes for America. On January 17, 1966, a B-52G USAF bomber collided with a KC-135 tanker during a refuelling mission at 31,000 feet over the Mediterranean Sea.

During the crash, three MK28-type hydrogen bombs headed for land in the small fishing village of Palomares in Almeria, Spain.

Worse still, the explosives in two of the weapons detonated on impact, contaminating the surrounding area of almost one square mile with plutonium.

The fourth sunk off the coast of Spain and was recovered three months later.

Anxiety over risks of radiation and heat at the 2020 Tokyo Olympics

 

Controversy over radiation and heat surrounding Tokyo Olympics, HANKYOREH  By Kim Chang-geum, staff reporter : Aug.14,2019


  “…… Safety from radiation and heat at the Tokyo Olympics

Most of the issues related to the upcoming Tokyo Olympics, which are now only a year away, boil down to safety concerns over radiation and extreme heat. Some baseball and softball matches are scheduled to be held in a stadium located close to the Fukushima nuclear reactor that took direct damage during the 2011 earthquake. Korean civic groups have also pointed out that the Japanese government has failed to properly control water contaminated by radiation from the reactor. Plans to source some of the rice and ingredients for the Tokyo Olympics Athletes Village from Fukushima are adding to these concerns. Although the level of radiation measured in such rice is within the acceptable standards in Japan, it is believed to exceed Korean standards.


Extreme heat is another potential issue. After an open water test competition in Odaiba Seaside Park, Tokyo, on Aug. 11, Sports Nippon reported, “Many athletes complained about a foul odor and the high water temperature, and one male athlete made the shocking claim that it ‘smelled like a toilet.’” Although the Olympic Committee did not reveal the water temperature on that day, it has been reported that the temperature was 29.9 degrees Celsius at 5am. The International Swimming Federation (FINA) cancels events if the water temperature reaches 31 degrees Celsius. There have also been warnings about road races. On August 8, Yusuke Suzuki, Japan’s star race-walker and world record holder in the men’s 20km, stated, “I tried training on the Tokyo Olympics race-walking course. There was no shade, so it could cause dehydration.”
Tokyo Olympics delegation heads meeting from Aug. 20-22It appears that the issue of safety from radiation and concerns about food ingredients will be conveyed during the upcoming three-day meeting with the leaders of each country’s delegation in Tokyo on Aug. 20-22, and a request will be made to the Japanese Olympic Committee to change the name of Dokdo used on maps. If the representatives from each country do raise the radiation issue, the IOC will have no choice but to intervene. The Korean Sport & Olympic Committee is also considering providing separate Korean food to Korean athletes through specially prepared meals or lunchboxes.  …. http://english.hani.co.kr/arti/english_edition/e_international/905758.html

Confusion and secrecy following Russian explosion, backflip on evacuation of village

Russian military orders village evacuation, then cancels it, following explosion that killed five nuclear scientists, Secrecy surrounding an explosion that killed five nuclear scientists and caused a spike in radiation levels has sparked fears of a cover-up in Russia, with authorities backflipping on orders to evacuate a nearby village. https://www.abc.net.au/news/2019-08-14/russian-nuclear-explosion-mystery/11411470

Key points:

  • Medics who treated victims of an accident have been sent to Moscow for medical examination
  • Russia’s state weather service said radiation levels spiked in Severodvinsk by up to 16 times
  • Many Russians spoke angrily on social media of misleading reports reminiscent of Chernobyl

The explosion took place on Thursday at a naval weapons range on the coast of the White Sea in northern Russia.

State nuclear agency Rosatom said the accident occurred during a rocket test on a sea platform.

The rocket’s fuel caught fire after the test, causing it to detonate, it said in a statement carried by Russian news agencies.

Two days later, after a spike in radiation levels was reported, Rosatom conceded the accident involved nuclear materials.

On Tuesday (local time), the Russian military ordered residents of the small village of Nyonoksa to temporarily evacuate, citing unspecified activities at the nearby navy testing range.

But a few hours later, it said the planned activities were cancelled and told the villagers they could go back to their homes, said Ksenia Yudina, a spokeswoman for the Severodvinsk regional administration.

Local media in Severodvinsk said Nyonoksa residents regularly received similar temporary evacuation orders, usually timed to tests at the range.

Russia’s state weather service said radiation levels spiked in the Russian city of Severodvinsk, about 30 kilometres west of Nyonoksa, by up to 16 times following the explosion.

Emergency officials issued a warning to all workers to stay indoors and close the windows, while spooked residents rushed to buy iodide, which can help limit the damage from exposure to radiation.

‘People need reliable information’

Many Russians spoke angrily on social media of misleading reports reminiscent of the lethal delays in acknowledging the Chernobyl accident three decades ago.

US experts said they suspected the cause was a botched test of a nuclear-powered cruise missile commissioned by President Vladimir Putin.

Boris L Vishnevsky, a member of the St. Petersburg City Council, told the New York Times that dozens of people had called asking for clarification about radiation risks.

“People need reliable information,” Mr Vishnevsky told the Times.

“And if the authorities think there is no danger, and nothing needs to be done, let them announce this formally so people don’t worry.”

The five scientists that died in the explosion were buried Monday in the closed city of Sarov — which houses a nuclear research facility and is surrounded by fences patrolled by the military.

While hailing the deceased as the “pride of the atomic sector”, Rosatom head Alexei Likhachev pledged to continue developing new weapons. “The best tribute to them will be our continued work on new models of weapons, which will definitely be carried out to the end,” Mr Likhachev was quoted as saying by RIA news agency.

Medics who treated victims sent to Moscow

Medics who treated the victims of an accident were sent to Moscow for medical examination, TASS news agency cited an unnamed medical source as saying on Tuesday.

The medics sent to Moscow have signed an agreement promising not to divulge information about the incident, TASS cited the source as saying.

US President Donald Trump said on Twitter on Monday the United States was “learning much” from the explosion and the United States had “similar, though more advanced, technology”.

He said Russians were worried about the air quality around the facility and far beyond, a situation he described as “Not good!”

But when asked about his comments on Tuesday, the Kremlin said it, not the United States, was out in front when it came to developing new nuclear weapons.

“Our president has repeatedly said that Russian engineering in this sector significantly outstrips the level that other countries have managed to reach for the moment, and it is fairly unique,” Kremlin spokesman Dmitry Peskov said.Mr Putin used his state-of-the nation speech in 2018 to unveil what he described as a raft of invincible new nuclear weapons, including a nuclear-powered cruise missile, an underwater nuclear-powered drone, and a laser weapon.

Tensions between Moscow and Washington over arms control have been exacerbated by the demise this month of a landmark nuclear treaty.
