The U.S. Is Building a Nuclear Bomb That’s More Accurate Than Ever via Newsweek

The U.S. has built a better, smarter nuclear bomb capable of replacing all four of its predecessors and, as of last month, it’s ready to fly.

The U.S. Air Force said Thursday it conducted an inert test in March of an upgraded version of one of its primary nuclear gravity bombs, the B61, in an effort to refurbish the nuclear arsenal of the nation with the second-largest nuclear weapons stockpile in the world. The long-awaited upgrade comes amid a new effort by President Donald Trump to conduct a massive review of the nation’s nuclear capabilities.

An F-16 dropped the non-nuclear B61-12 over the Nellis Test and Training Range Complex in Nevada, assessing functions such as the weapon’s fire control system, radar altimeter, spin rocket motors and weapons control computer. The B61-12 was set to replace four current models—the B61-3, -4, -7, and -10, according to the Aviationist. The initiative, which hoped to see the weapon in production by 2020, was part of the nuclear life-extension program overseen by the Air Force Nuclear Weapons Center in conjunction with the Department of Energy’s National Nuclear Security Administration.

[…]

That same 2014 report said that the $10.4 billion life-extension program and the $1.4 billion tail kit assembly of 500 B61-12 weapons made this the most expensive bomb project ever. Additional hundreds of millions would reportedly be spent integrating the weapons to fit aircraft and maintain stockpiles in Europe. Costs would be saved, however, by consolidating the capabilities of four previous B61 models into one weapon and retiring the B61-11, called the “bunker buster” for its nuclear earth-penetrating ability.

[…]

Modernizing the U.S.’s entire nuclear arsenal would cost $400 billion by 2026, according to a figure released Tuesday by the Congressional Budget Office. Some military officials have reportedly suggested abandoning nuclear projects such as the Long-Range Standoff nuclear cruise missile (LRSO) in favor of optimized conventional strike options.

Warren, Markey critical of NRC exemption for Pilgrim plant via The Daily News of Newburyport

BOSTON – Federal regulators on Monday ruled in a decision blasted by the state’s two U.S. senators that the owners of Pilgrim Nuclear Power Station will not have to re-evaluate the risks of earthquakes and floods to the Plymouth nuclear plant or upgrade the vent system intended to prevent explosions in accident scenarios.

The Nuclear Regulatory Commission on Monday granted an extension for Entergy, the company that owns and operates Pilgrim, to comply with regulations for the plant’s “reliable hardened containment vents capable of operation under severe accident conditions.”

The NRC also waived Entergy’s obligation to further study the risks of floods or earthquakes because it said that by the time the study could be finished and implemented, the nuclear plant will be closed.

Pilgrim is scheduled to shut down for good by May 31, 2019, but, citing the plant’s safety record and low rating by the NRC, critics of the plant have been repeatedly calling for it to close immediately.

U.S. Sen. Edward Markey blasted the NRC’s decisions Monday, arguing that allowing Pilgrim to avoid heightened safety measures “represents an abdication of (the NRC’s) role as a safety regulator.”

The “decision by the NRC undermines the safety of Massachusetts communities living in the shadow of Pilgrim,” Markey said in a statement. “When Entergy announced its intention to cease operations at Pilgrim, the NRC promised that it would hold Entergy responsible for running the plant as safely as possible until that time. By providing exemptions from requirements meant to address the risk of terrorist attacks or severe accidents such as natural disasters, the NRC has broken its promise.”

The hardened containment vent system, or HCVS. is intended to “avoid an overpressure condition involving the reactor containment building that could lead to a failure of that containment” and could result in a nuclear accident similar to the 2011 meltdown at Fukushima Daiichi Nuclear Power Station in Japan.

[…]

U.S. Sen. Elizabeth Warren, displeased with the ruling, said the NRC “continues to ignore the concerned voices of Massachusetts communities” in making its decisions.

“Pilgrim may be shutting down in 2019, but that date should have no bearing on Entergy’s – and the NRC’s – responsibility to ensure safe plant operations, each and every day,” Warren said in a statement. “The risks are too high to allow Entergy to stumble forward for the next two years and disregard investment in critical safety upgrades.”

柏崎刈羽原発 活断層? 13万年前以降に活動、新潟大名誉教授ら発表 再稼働に影響も /新潟 via 毎日新聞

 県内の地質学者などで構成する「柏崎刈羽原発活断層問題研究会」(大野隆一郎代表)は17日、東京電力柏崎刈羽原発敷地内にある複数の断層について、約13万年前以降に活動した「活断層」の可能性があると発表した。東電は「活断層はないというこれまでの評価は変わらない」としているが、原子力規制委員会の新規制基準では12万から13万年前以降に活動した可能性のある断層は活断層と評価されるだけに、事態の推移によっては原発再稼働の判断に影響を与える可能性が出てきた。

[…]

東電は、安田層に含まれる火山灰層「刈羽テフラ」の組成が青森・下北半島沖で報告されている20万から23万年前の火山灰と似ていることなどを根拠に、テフラ周辺の安田層の堆積(たいせき)時期を20万から三十数万年前と評価。テフラの上にある安田層と分ける形で「古安田層」と新たに名付け、23本の断層は古安田層内で生じたものだとした。規制委も同原発6、7号機の審査過程で東電の主張を「おおむね妥当」と認めている。

 一方、研究会は、刈羽テフラは柏崎市藤橋に分布する火山灰「藤橋40」と組成成分が「完全に一致」していることに着目。東電もこの一致点は認めているが、研究会は、藤橋40は12万から13万年前の地層に挟まれていることから、刈羽テフラは古くても13万年前の火山灰層であると結論づけ、20万から23万年前とする東電の推定を「科学的推定とは言えない」と評価した。敷地内の断層は活断層である可能性があるとして、東電に「調査・解析結果の全面的な見直し」を求めるという。

 研究会のメンバーで県技術委員会の委員も務める立石雅昭・新潟大名誉教授(地質学)は「東電の主張は従来の地質学・地形学で広く認められてきた科学的推論とは異なる」と話している。

Downwinders get mixed support via Messenger Index

Since the summer of 2004, the Messenger Index has championed the voice of downwinders — those who were hit with atomic fallout during above-ground tests in the 1950s and ‘60s. Compensation established for some victims specifically excluded the hardest hit counties from any sort of recognition.

Nearly 13 years later, the cause continues at the national level through attempts to amend the Radiation Exposure Compensation Act of 1990. This acknowledged those living in a handful of counties in Utah, Arizona and Nevada. Those receiving much lower doses fallout of cancer-causing Iodine-131.

[…]

“For all the people who are sick and dying and who have died, I feel like they’ve been let down by our government,” Henderson said.

In January, both of Idaho’s Senators introduced the latest legislation S.197, the seventh version of RECA amendments. This expands the geographic area and would include all Idahoans who have developed cancers from the fallout.

A few weeks later, Guam, also impacted by nuclear tests, sent a resolution of support for the Senate amendment.

On April 6, a companion House bill, H.R. 2049, was introduced listing 25 sponsors in the House. Labrador and Simpson are not among the sponsoring Representatives who come from Arizona, California, Colorado, Florida, Massachusetts, Nevada, New Mexico, New York, Oregon, Texas and Washington, as well as Guam.

[…]

If you would like to help “push” the amendment out of committee Henderson asks you to write a short letter. While most people are inclined to write lengthly memories about those who’ve passed on or their own personal battles with cancer, these often aren’t read. A simple letter usually works better. Something that says, “We need this to pass. It’s been far too long,” she said.

In her years of letter-writing campaigns, Henderson has also discovered form letters don’t carry as much weight as a personal letter either.

Write your letter to Honorable Senator Chuck Grassley, United States Senate Committee on the Judiciary, 224 Dirksen Senate Office Building, Washington DC 20510-6050.

Funds sought to save ‘Hiroshima Panels’ paintings from insects via The Asahi Shimbun

HIGASHI-MATSUYAMA, Saitama Prefecture–The celebrated “Hiroshima Panels” series of artworks, inspired by eyewitness accounts of the atomic bombing carnage, have suffered serious insect damage and need a new facility to prevent further deterioration.

The paintings were drawn by Iri Maruki (1901-1995) and his wife, Toshi Maruki (1912-2000), who founded the Maruki Gallery for the Hiroshima Panels here in 1967.

Since 2012, museum staff have noticed white spots and irregular lines spreading across the traditional Japanese paper of the 14 paintings on permanent exhibit.

“For about the last two years, the number of insects has suddenly increased, and it is hard for us to keep repairing them,” a museum official said.

The works have not been kept in glass cases. The late artists wanted visitors to see them from up close in a natural setting.

The museum, operated through admission fees and donations, has decided to build a new temperature- and humidity-controlled building and implement other anti-insect measures. It is calling for donations, with a goal of 500 million yen ($4.6 million).

Buyouts coming for homeowners near West Lake Landfill? via St. Louis Post-Dispatch

For some north St. Louis County homeowners, the prospect of exposure to the area’s decades-old radioactive contamination is only one source of concern: Another is what to do with their homes, which could struggle to attract buyers.

“They didn’t anticipate buying a house or renting a house in a community that has a legacy of radioactive waste from the 1970s,” said Sen. Maria Chappelle-Nadal, D-University City. “Who would buy a home like that?”

[…]

The bill applies to homes that have been deemed uninhabitable by a “federal or state environmental or health agency” owing to contamination the resident is not responsible for.

Homeowners would also be eligible for buyouts if they live within a 1.55-mile radius of any area where at least 20 percent of samples by the Environmental Protection Agency or U.S. Geological Survey show radium in groundwater to exceed maximum contaminant levels.

The legislation is Chappelle-Nadal’s latest effort geared toward radioactive contamination in the area. In the vicinity of Bridgeton’s West Lake Landfill — which contains radioactive waste dating to the time of the Manhattan Project — Chappelle-Nadal says the bill would apply to residents of the 91 homes comprising the Spanish Village neighborhood and a nearby mobile home park.

False promise: nuclear power: past, present and (no) future via Ecologist

Nuclear power was originally sold on a lie, writes Dave Elliott. While we were being told it would make electricity ‘too cheap to meter’, insiders knew it cost at least 50% more than conventional generation. Since then nuclear costs have only risen, while renewable energy prices are on a steep decline. And now the nuclear behemoths are crumbling … not a moment too soon.

In a December 1953 speech to the United Nations, President Dwight D. Eisenhower launched the ‘Atoms for Peace’ programme, saying:

“The miraculous inventiveness of man shall not be dedicated to his death but consecrated to his life.”

He claimed that “peaceful power from atomic energy is not a dream of the future. That capability, already proved, is here – now – today.” And the USA would help to ensure it could be used worldwide.

However, his advisors soon told him that it wasn’t viable. A classified internal State Department Intelligence Report, circulated in January 1954, ‘Economic Implications of Nuclear Power in Foreign Countries‘, warned that the introduction of nuclear power would

” … not usher in a new era of plenty and rapid economic development as is commonly believed. Nuclear power plants may cost twice as much to operate and as much as 50 percent more to build and equip than conventional thermal plants.” [Quoted by Mara Drogan in ‘The Nuclear Imperative: Atoms for Peace and the Development of U.S. Policy on Exporting Nuclear Power, 1953-1955 Diplomatic History 40 Issue 5 948-974.]

Nonetheless, the nuclear juggernaut rolled on, with, US Atomic Energy Commission Chairman Lewis Strauss, in a 1954 address to science writers, claiming: “It is not too much to expect that our children will enjoy in their homes electrical energy too cheap to meter.”

[…]

But for our politicians, the nuclear dream never died

But that didn’t stop Marget Thatcher from pushing ahead with a new nuclear plant (a PWR) at Sizewell, work on it starting in 1987. Or Tony Blair later trying to relaunch a new programme “with a vengence”. That has still yet to happen. But it’s pending, with the £24 billion Hinkley Point C European Pressurised-water Reactor (EPR), if it goes ahead, being the first new UK plant in 30 years.

Fukushima, in 2011, had intervened, slowing the nuclear programme worldwide, and creating liabilities of hundreds of billions of dollars. But the UK has pressed ahead with plans for maybe 18GW of new plant – delivering around 30% of UK electricity in the 2030s.

This expansion is based on so-called ‘Generation III’ reactors, basically upgrades of the Generation II PWRs and similar designs that have been the mainstay of nuclear so far. The new versions are unlikely to be any more competitive against cheap gas and increasingly cheap renewables.

The nuclear industry still has hopes for the French EPR, the Toshiba / Westinghouse AP1000 and the Hitachi ABWR – an upgrade of the Fukushima boiling water reactor design.

But the EPRs being built in France and Finland, Flamanville and Olkiluoto, are both around eight years late and three times over budget. Flamanville’s gigantic stainless steel reactor vessel and dome is also suffering from serious metallurgical flaws which may yet prevent its completion.

The two AP1000s being built in the USA have also been delayed, creating losses of over $10 billion that have pushed Westinghouse into bankruptcy, and its Japanese parent company, Toshiba, into what may prove to be a terminal financial meltdown. The two ABWRs under construction in the US are also seriously behind schedule.

Are France’s ageing nuclear plants safe? via France24

Despite heightened surveillance and draconian control measures, the answers from nuclear analysts is far from unanimous. Despite these questions, the French power giant that manages them, EDF, wants to prolong their life by ten or even 20 years. Furthermore, the public utility’s finances are at least €37 billion in debt.

What’s more, EDF is due to build two more reactors in Britain – this after embarrassing revelations of neglect relating to the manufacturer of the reactors, Creusot.

規制委員長に更田氏=原発審査を主導-政府人事案 via Jiji.com

政府は18日、原子力規制委員会の次期委員長に更田豊志委員長代理(59)を充てる国会同意人事案を、衆参両院の議院運営委員会理事会に提示した。9月で任期が切れる田中俊一委員長(72)の後任で、人事案は今国会で同意される見通し。

更田氏は原子力工学が専門で、2012年9月の規制委発足時からのメンバー。日本原子力研究開発機構で核燃料や原子炉の安全研究に取り組んだ実績を買われ、規制委では原発の設備対策の要求を引き上げる新規制基準の策定に関わった。

新基準の施行後は原発設備の審査を担当。主導的な役割を果たしたほか、東京電力福島第1原発事故の廃炉作業を監視する検討会の座長を務めた。

第1原発の汚染水対策では、東電や経済産業省資源エネルギー庁の見通しの甘さを指摘。再任された15年9月の記者会見では今後の廃炉作業について「より難しくなってくる」と述べていた。

原則40年と定められた運転期間をめぐっては、関西電力高浜原発1、2号機(福井県)、美浜原発3号機(同)で延長を認めた。
