Disposal beats MOX in US comparison via World Nuclear News

America is reconsidering how it will dispose of 34 tonnes of plutonium as the previous plan involving a MOX plant has been said to be twice as costly as a dilution and disposal option in a leaked Department of Energy (DOE) report.
The plutonium arises from a June 2000 nuclear weapons reduction agreement with Russia under which both countries would put 34 tonnes of plutonium beyond military use. Russia opted to use its plutonium as fuel for fast reactors generating power at Beloyarsk.
The USA, meanwhile, decided to build a mixed-oxide (MOX) nuclear fuel plant at Savannah River, where the plutonium would be mixed with uranium and made into fuel for light-water reactors. The design is similar to Areva’s Melox facility at Marcoule, but modified to handle metal plutonium ‘pits’ from US weapons and their conversion from metal to plutonium oxide. It is this part of the process that has been problematic. Construction started in 2007 with an estimated cost of $4.9 billion but work ran into serious trouble before being ‘zeroed’ in the DOE’s 2014 budget, putting development on ice.
The Union of Concerned Scientists yesterday published what it said was an unreleased DOE report that compared the cost of completing the MOX plant to other options. Use in fast reactors was considered briefly, but with this technology not readily available in the near term, the prime comparison was against a ‘dilution and disposal’ option which would see the plutonium mixed with inert materials and disposed of in the Waste Isolation Pilot Plant, or WIPP, in New Mexico.
Despite being 60% built, the MOX plant still needs some 15 years of construction work, said the leaked report, and then about three years of commissioning. Once in operation the plant would work through the plutonium over about 10 years with this 28-year program to cost $700-800 million per year – a total of $19.6-22.4 billion on top of what has already been spent. Not only is the price tag very high, but the timescale is too long: the report said this would not meet the disposal timeframe agreed with Russia.

川内原発 トラブルで出力上昇作業を延期 via NHK News Web

今月11日に再稼働した鹿児島県にある川内原子力発電所1号機で、発電に使った蒸気を水に戻す設備でトラブルがあり、九州電力は、発電機の出力を上げる作業を延期すると発表しました。九州電力は今のところ運転に問題はなく、原子炉の運転や発電、送電は続けるとしています。
九州電力によりますと、川内原発1号機で20日、発電に使った蒸気を冷やして水に戻す「復水器」と呼ばれる設備に異常があることを示す警報が鳴りました。九州電力が復水器の水の成分を調べたところ、塩分の濃度が通常より高いことが分かったということです。
このため九州電力は蒸気を冷やすために取り込んでいる海水が復水器の中の水に混ざり込んだとみて21日予定していた発電機の出力を75%から95%まで上げる作業を延期すると発表しました。
(略)

蒸気を冷やして水に戻すための装置

今回トラブルがあった復水器は発電用のタービンを回したあとの蒸気を冷やして水に戻すための設備で、川内原発1号機には3台あります。中には1 台当たり、2万6190本の細い管があり、その内側に海水を流して管の外側の蒸気を冷やし水に戻す仕組みで、戻した水はポンプで蒸気を作り出す蒸気発生器 に送り出されます。本来、海水と蒸気は混ざらない構造ですが、復水器の細い管に腐食などで穴が開くと、海水が混入し、蒸気発生器に悪影響を及ぼすおそれが あります。
川内原発は加圧水型と呼ばれるタイプで、原子炉で発生した熱で直接蒸気を作るのではなく、放射性物質を含まない2次系の水を蒸気発生器 で沸騰させて蒸気を作ります。このため安全上、蒸気発生器の腐食などを防ぐ対策が重要で、今回のような海水の漏えいを想定して、配管の途中に塩分を取り除 く装置が設置されているほか、定期検査でサンプル検査をして損傷状況を調べることになっています。

原子炉運転に影響ないと確認

原子力規制庁では、21日午前9時ごろ、九州電力から報告を受けて、現地の検査官がトラブルの状況や原子炉の運転に影響がないことを確認したということで、今後は、九州電力が行う原因の調査や調査結果を踏まえた対処方法を確認していくことにしています。

Army Corps confirms radioactive contamination in yards by Coldwater Creek via St. Louis Post-Dispatch

HAZELWOOD • Officials in charge of cleaning up pollution left over from the country’s early nuclear weapons program say there’s radioactive contamination in several residential yards that back up to Coldwater Creek.

The Army Corps of Engineers confirmed Wednesday that it had discovered what it described as “low-level” radioactive contamination from thorium 230, a uranium decay product. It has likely been on the properties for decades, carried by a creek that flows through several miles of subdivisions in north St. Louis County.

It is the first time in more than 15 years of Corps-directed cleanups in the region that the government has confirmed radioactive contamination on residential properties.

[…]

Since 2013, the Corps has been remediating Coldwater Creek, which was contaminated with uranium processing waste stored at sites near Lambert-St. Louis International Airport. The Corps is also cleaning up a site north of downtown St. Louis where Mallinckrodt, a former chemical company that now makes medical products, used to process uranium for the Manhattan Project and the early nuclear program.

“We have not had confirmation that we actually had radionuclides in people’s backyards,” said Jenell Wright, who lived in the area near the creek for almost 30 years and sits on a panel overseeing the cleanup. “This is massive.”

But she and others who have pushed for more testing along the creek’s floodplain aren’t surprised.

[…]

Wright noted that when Coldwater Creek flooded while she was growing up, it would cause sewer backups into people’s basements, and she suspects some contamination could have entered there. She also noted that development in the area may have moved contamination beyond the creek’s floodplain.

She and others have begun tracking cancer rates in former residents, and she said two of her friends recently died. One was in his 40s.

All of this work was not in the original FUSRAP cleanup budget, Wright said. As the Corps continues to test more property along the creek and follow the trail of radiation, she said Congress needs to step up with more funding. The Corps is doing a good job, she said, but a backlog of cleanup projects could continue to grow without the budget.

“We have a huge problem,” she said. “They understand they’re at the tip of the iceberg.”

Children Given Lifelong Ban on Talking About Fracking via The Guardian

wo young children in Pennsylvania were banned from talking about fracking for the rest of their lives under a gag order imposed under a settlement reached by their parents with a leading oil and gas company.

The sweeping gag order was imposed under a $750,000 settlement between the Hallowich family and Range Resources Corp, a leading oil and gas driller. It provoked outrage on Monday among environmental campaigners and free speech advocates.

The settlement, reached in 2011 but unsealed only last week, barred the Hallowichs’ son and daughter, who were then aged 10 and seven, from ever discussing fracking or the Marcellus Shale, a leading producer in America’s shale gas boom.

The Hallowich family had earlier accused oil and gas companies of destroying their 10-acre farm in Mount Pleasant, Pennsylvania and putting their children’s health in danger. Their property was adjacent to major industrial operations: four gas wells, gas compressor stations, and a waste water pond, which the Hallowich family said contaminated their water supply and caused burning eyes, sore throats and headaches.

Gag orders – on adults – are typical in settlements reached between oil and gas operators and residents in the heart of shale gas boom in Pennsylvania. But the company lawyer’s insistence on extending the lifetime gag order to the Hallowichs’ children gave even the judge pause, according to the court documents.

The family gag order was a condition of the settlement. The couple told the court they agreed because they wanted to move to a new home away from the gas fields, and to raise their children in a safer environment. “We need to get the children out of there for their health and safety,” the children’s mother, Stephanie Hallowich, told the court.

She was still troubled by the gag order, however. “My concern is that they’re minors. I’m not quite sure I fully understand. We know we’re signing for silence for ever but how is this taking away our children’s rights being minors now? I mean my daughter is turning seven today, my son is 10.”

The children’s father, Chris Hallowich, went on to tell the court it might be difficult to ensure the children’s absolute silence on fracking – given that their ages and that the family lives in the middle of a shale gas boom.

“They’re going to be among other children that are children of people within this industry and they’re going to be around it every day of their life, that if they in turn say one of the illegal words when they’re outside of our guardianship we’re going to have difficulty controlling that,” he said. “We can tell them, they can not say this, they can not say that, but if on the playground…..”

水産物輸入禁止:政府、韓国をWTO提訴 パネル設置要請via 毎日新聞

政府は20日、韓国が東京電力福島第1原発の事故を理由に福島など8県の水産物輸入を全面禁止しているのは不当として、世界貿易機関(WTO)に提訴した。原発事故を巡る輸入規制で、日本政府が他国を提訴するのは初めて。

 政府の規制撤廃要請に韓国側が応じなかったためで、政府は20日、WTOに紛争処理小委員会(パネル)の設置を要請した。8月31日にスイスのジュネーブで開かれるWTO紛争解決機関会合で審議され、9月中にもパネル設置が認められる見通し。最終的な結果が出るのは2016年以降になるとみられる。菅義偉官房長官は20日の記者会見で「WTOの結論を待つことなく、規制を早く撤廃すべきだ」と述べた。

Daniel Ellsberg Arrested at Lawrence Livermore Lab on 70th Anniversary of Nuclear Bombing of Hiroshima via Reader Supported News

ietnam War-era whistleblower Daniel Ellsberg, 84, known for releasing the Pentagon Papers in 1971, has once again been arrested for protesting U.S. nuclear weapon arsenals, this time at Lawrence Livermore Labs on Thursday, August 7, the 70th anniversary of the atomic bombing of Hiroshima, Japan. Ellsberg was arrested with fifty other protestors from the Bay Area, while 250 more joined in support to draw attention to the 2016 funding of Lawrence Livermore Labs: $1 billion for nuclear weapons, designing new long-range warheads, and upgrading existing nuclear arsenals.

According to a video of the protest, Ellsberg, a former Defense Department analyst, addressed the protestors outside the fence of Lawrence Livermore Lab, stating, “The killing at Hiroshima was mass murder.… In the target plans that I worked on, and ones I worked on in Russia, the smoke will go into the stratosphere as it did in Hiroshima by higher firestorm. But simultaneously, thousands of cities, with pillars of smoke, will join around the globe blotting out the sunlight sufficiently to kill harvests around the world, and condemn nearly the entire population of the world to death. It’s the Doomsday Machine, The End. We’ve known that, not at the time of the Cuban Missile Crisis, but for the last twenty-five years, and yet these threats go on; the threats go on. They are threats of ending nearly all life. It’s never a good day to die, but it is a good day to get arrested.”
[…]
To understand the authenticity of the knowledge of Daniel Ellsberg, look to his bio: In the early 1960s, Ellsberg, a former Rand employee, was a consultant to the Departments of Defense and State, and to the White House, where he specialized in resolving problems of the command & control of nuclear weapons, nuclear war plans, and crisis decision-making. He drafted the Secretary of Defense Guidance to the Joint Chiefs of Staff concerning operational plans for conducting a general nuclear war.

He has been arrested in nonviolent civil disobedience actions close to one hundred times, with 50+ geared to protesting nuclear weapons, e.g. at Rocky Flats Nuclear Weapon Production Facility, the Nevada Test Site, Livermore Nuclear Weapons Design Facility, the vicinity of Ground Zero at the Nevada Test Site, and at the Vandenberg Missile Test Site. Over the past few years, he has been arrested at Vandenberg Air Force Base to protest the testing of dummy ICBMs (Intercontinental Ballistic Missiles) to show the danger of having land-based missiles.

[…]
Breaking News: On August 19, 2015, just two weeks after Ellsberg’s recent arrest on the 70th anniversary of the atomic bombing of Hiroshima and Nagasaki, the U.S. plans to once again launch a dummy Minuteman III Intercontinental Ballistic Missile (ICBM) from Vandenberg Air Force Base (in California). It will target the Kawajalein Atoll in the Republic of the Marshall Islands (RMI). This test comes also in the midst of the major lawsuits filed by the Marshall Islands, called the Nuclear Zero lawsuits, which are attempting to hold the nine nuclear nations accountable for not adhering to the provisions in the Non-Proliferation Treaty to disarm. The lawsuit has been appealed to the Ninth Circuit Court of Appeals (SF). David Krieger, president of the Nuclear Age Peace Foundation and consultant to the Marshall Islands in the Nuclear Zero lawsuits, stated today, “While the U.S. continues to develop and test launch its nuclear-capable missiles, the Marshall Islands is seeking a judgment against the U.S. and other nuclear-armed nations for failure to fulfill their nuclear disarmament obligations under international law.” Krieger previously was arrested with Ellsberg at Vandenberg Air Force Base in protest of other test launches of ICBMs.

Police breaches at nuclear stations ‘like the Simpsons’ via The Scots Man

A POLICE officer disciplined for using eBay has emerged as one of 51 disciplinary breaches across 11 nuclear power stations in Britain.

The incidents all occured in the past three years and were tracked by the Civil Nuclear Constabulary (CNC), the police force that guards the UK’s atomic power plants.

Another officer fell asleep on duty while yet another mishandled a firearm – incidents described by critics as “like something out of The Simpsons”.

The breaches occurred since January 2013 at 11 civil nuclear sites across England, Scotland and Wales, although the data does not reveal the location of each incident.

[…]

One of the most serious breaches include a constable who in 2013 for “dangerous handling of firearm”, resulting in them resigning during the investigation.

A total of five members of staff were disciplined for improper care of equipment, and another was given a final written warning for failure in firearms handling.

Worryingly, two constables and a sergeant were also convicted of criminal offences whilst employed by the CNC.
