福島第1廃炉、気中工法で 政府・東電、近く決定 via 東京新聞

 東京電力福島第1原発の廃炉作業で最難関となる1~3号機からの溶融核燃料(デブリ)の取り出しについて、廃炉の技術支援を担う原子力損害賠償・廃炉等支援機構が、3基とも原子炉格納容器を水で満たさない「気中工法」を軸に、最初は格納容器底部の横側から重点的に始める方針を検討していることが4日、分かった。デブリ取り出しの具体的手順が明らかになるのは初めて。

格納容器全体を水で満たす「冠水工法」は、現時点では採用しない。

【ガチ】NASAが火星に「原発」を建設予定であることが発覚! 火星植民地化に向け、2カ月後に実験開始!via Tocana

(抜粋)

火星に核分裂炉を建設する目的とは?

今年3月、米大統領ドナルド・トランプ氏が「2033年までに人類を火星に送り込むよう指示する法案」に署名したこともあり、この度NASAが有人火星探査に向けた具体的なプランの1つを公開。なんと、火星でのエネルギー問題を解決するため、ウラン原子を利用した「核分裂反応炉」の火星での運用を目指し、今年中に実験を開始するというのだ!

英紙「The Independent」(7月2日付)などによると、有人火星探査を実現する上で最も重要な課題はエネルギー発電であり、NASAの技術部門では、過去3年間にわたり「小型核分裂反応炉開発計画」を温めてきたという。そして、遂に地球でのテスト運用を今年9月から2018年1月にかけて実施するということだ。

(略)

実は、同様の計画は1960年代にも2つ存在した。1つは「SNAP」と呼ばれる計画で、熱電発電装置を利用するというもの。2つ目は、プルトニウム238の崩壊熱による原子力電池を利用したもので、これは現在、火星探査機「キュリオシティ」に実装されている。また、SNAP計画の一環として、1967年と1988年に核分裂反応炉も開発・運用されたが、わずか500Wを発電した時点で故障し、現在も地球の軌道を彷徨っているという。

Rosatom loses hope in its international nuclear builds, eyes renewables via Bellona

Amid decreasing world demand for nuclear energy, Russia’s state nuclear corporation last week warned it would likely be receiving fewer requests to build nuclear power plants abroad.

The announcement marks a sharp departure for the corporation, which until recently has posed its contracts with other countries as the bread and butter of its bottom line – as well as a potent tool for broadening Moscow’s sphere of political influence.

But there’s a silver lining to the nuclear monolith’s recent disillusionment with its traditional lifeblood: A possible, albeit modest, shift in the direction of renewable energy and battery technologies.

Speaking at last month’s Tekhnoprom-2017 conference, a technical conference in the Siberian city of Novosibirsk, Rosatom’s deputy director Vyacheslav Pershukov called the market for nuclear power stations abroad “exhausted.”

“We see that the market is contracting, and for the sustainable growth of the corporation…we must make our money on something other than nuclear technology,” he said, according to the RBK news agency.

Repeated radiation warnings go unheeded at sensitive Idaho nuclear plant via Santa Fe New Mexican

Ted Lewis knew the plutonium plates at the government lab where he worked could leak potentially lethal radioactive dust.

He had seen it occur in the 1970s, when he was helping load some of those plates into a nuclear reactor at the lab near Idaho Falls, Idaho. A steel jacket enclosing one of the plates somehow cracked, spilling plutonium oxide particles into the air. But Lewis and his colleagues were lucky — they were wearing respirators and given cleansing showers, so their lives weren’t endangered.

Three decades later, Lewis, an electrical engineer who had become chairman of the lab’s safety committee, had a bad feeling this could happen again, with a worse outcome. And he turned out to be right.

[…]

He said in a sworn court deposition in January 2016 that he shared his concerns with at least 19 others at the laboratory, which holds one of the world’s largest stockpiles of plutonium, the explosive at the heart of modern nuclear weapons. But they didn’t respond, he said, and some of the precautions he urged — checking the plates more carefully before they were unwrapped and repackaged for shipment and setting up a decontamination shower — were ignored.

Then, at 11:04 a.m. on Tuesday, Nov. 8, 2011, Lewis’s fears came to life in a cavernous room at the lab where workers were readying some plates the size of Hershey’s chocolate bars for shipment to other federal sites and to researchers. The workers had a lead shield between themselves and the plates, but the table where they sorted the plates wasn’t sealed, and none of them had respirators on.

So when a nuclear material handler named Ralph Stanton noticed that one of the plates had a label warning that its corner was “swollen,” he asked a shift supervisor for guidance. The supervisor phoned one of the lab officials whom Ted Lewis had briefed on his worries, but after finishing the call the official told the workers to continue, according to an internal Department of Energy report in January 2012.

[…]

Accidents persisted at the lab after the 2011 incident. But officials in Washington charged with overseeing worker safety — and annually deciding how much profit BEA would be paid based on its performance — decided not to let the incidents seriously dent the company’s revenues.

They failed, in short, to use either of two key federal levers available to force improved workplace protections for those involved in handling the nuclear materials that underpin America’s security — by imposing fines or cutting profits enough to compel an end to new safety hazards, or by holding up or completely blocking an extension of the lab’s private management contract.

During the period of the five worker radiation contaminations from 2011 to 2014, the Energy Department paid BEA $68.5 million in pure profits, amounting to 92 percent of the maximum its contract allowed, the Center’s tally shows. (Its actual expenses in running the lab were reimbursed in full.)

[…]

They didn’t learn about it until three months after their highest exposure, the investigation report said, because the technicians who read and record their exposures didn’t make it a priority to tell them. As a result, one exceeded his annual company-set radiation dosage limit of 10 rem in 2010, and the other worker nearly exceeded his limit.

The reports said workers should have been told along the way of their monthly exposures, so they were not surprised by their cumulative doses. Also, in a problem that would recur in multiple incidents, the lab did not check the glove box for a particular type of radiation commonly exuded by the material they worked on, according to the BEA investigative report. That type of radiation is not harmless — it can cause cell damage, cancer, and even death in high doses.

[…]

Numerous problems contribute to the mass inhalation incident

Then came the radiation contamination of 16 workers on Nov. 8, 2011, which occurred in a white, mound-shaped building that was once home to a mothballed nuclear reactor and still has a massive vault resembling a walk-in freezer. It’s there that the government stores several metric tons of surplus plutonium, which the Department of Homeland Security and the NNSA use to help develop and refine radiation detection devices deployed by Washington at ports and border crossings around the globe.

[…]

The gravity of their exposures has nonetheless been contested, partly because the urine samples the workers provided on the day of their exposure were altered by the medication that four of them, including Braase, Simmons and Stanton, were swiftly given. In his lawsuit, Simmons said BEA radiation control officials initially showed him a report saying that his bone surface dose could have been as high as 265 rem, a level five times the annual federal occupational dose limit, 212 times the Occupational Safety and Health Administration limit, and 2,650 times the annual federal dose limit for the public.

[…]

Even Simmons’ claimed exposure of 265 rem would not be worrisome if it were an estimate of exposure to the bone over 50 years, Kathren said. But he added that “if a guy had gotten 250 rem in the first year, I would be very concerned.”

Uncertainty about exactly how — or when — the inhalation of plutonium might affect his health haunts Stanton. “I’m always worried this will be what comes back and gets me,” he said.

Stanton and Simmons also say they encountered public hostility from some of their colleagues after they pressed managers and health officials from the company for details of their contamination levels and lax workplace safety practices. “Brian and I sat alone at lunch,” Stanton recalled. “We were total outcasts. But when we were alone and saw them in the hall, people that wouldn’t acknowledge you around management thanked us.”

[…]

New contamination incidents

The plutonium contamination of 16 BEA workers was followed by two other significant radiation exposures, with the first occurring in August 2014, when workers in the Fuel Manufacturing Facility, a low structure next to the building where the plutonium exposures occurred, were fabricating radioactive americium in a glove box.

[…]

The fifth contamination incident occurred just two weeks later, in a long, low building just a block from the Idaho fuel manufacturing facility known as the Analytical Laboratory. There, on Sept. 9, 2014, a researcher poured some nitric acid containing plutonium-238 into another bottle, all inside a small room with a special exhaust fan. A week later, routine monitoring detected plutonium contamination in the room. Those involved had their noses swabbed, and two workers had nasal contamination, but no plutonium was detected in their lungs. The room was then shut for a week for decontamination.

Here’s A Closer Look At That Nuclear Bunker Filled With Mario Murals via Kotaku

[…]

The bunker’s fascination with Mario first surfaced (as far as I can tell) back in 2014 after it was pointed out in an NPR story. Nuclear bunkers are obviously extremely secretive and hard to get access to, so there isn’t exactly a whole lot of info about them. But after a bunch of bad press, including stories about the people in charge of nukes cheating to pass tests and falling asleep on the job, the Air Force has been keen to shift the narrative surrounding the country’s missile sites

As a result, NPR was in a position a few years ago to reveal that most bunkers have themes. Some are decked out in Star Wars iconography, while others, like Foxtrot-01, prefer Nintendo’s mascots. A mural of Mario and Bowser standing across from one another with a skull and crossbones mushroom cloud in-between was a sort of WTF moment undercutting the Airforce’s attempt at gravitas, but at least it was about nuclear war. Also Mario is scowling. The NPR story tried to offer context for the scene,

Three years later, Foxtrot-01 is back at it, this time giving Britain’s Sky News a special tour of the facility and some insight into what capability the site provides for our Commander-in-Chief, President Trump. “If we have a rapidly emerging crisis that requires the use of ICBMs we can respond to the President’s direction in minutes,” says Colonel Matthew Dillow, the Vice Commander of the 90th Missile Wing. 

Moments later, the report cuts to its correspondent, Cordelia Lynch, in front of a Super Mario Bros. 3 box art.

By some estimates, there are currently more than 15,000 nuclear missiles on earth. Possible over 20,000. That’s more than enough to make the entire planet uninhabitable. Should a large scale nuclear war ever occur, it’s likely that more than a few of those will be fired out of a whole in the ground where the walls are covered with Marios.

Is there a better metaphor for the absurdity of nuclear strategy? I’m struggling to think of one.
