Fukushima Update- Part 1

First of all let’s survey the damage.  Reactors 1, 2, and 3 suffered core meltdowns that breached the steel containment vessels leaving leaks that have been releasing highly radioactive cooling water AND molten nuclear fuel into the concrete basement below the vessel.

This is kind of a containment vessel too and while there are no current indications that nuclear reactions are continuing in the escaped fuel slag that would burn through this floor and into the uncontained earth foundation of the plants, they’re not waterproof and there is no doubt at all that millions of gallons of highly radioactive water and perhaps some fine particulates are leaking into the environment uncontrolled.

This has led to a re-evaluation of cooling and clean-up strategies that continues because there are no really good answers.  Several radiation peaks indicating continued nuclear reactions in the melted and puddled fuel mean you can’t stop pumping water and the leaking makes it difficult to maintain a sufficient amount in the containment vessel to moderate the reaction (that’s why you get the peaks when the level dips too low).

There’s a continued risk of hydrogen explosions too and one of the reasons I mention that is because the one bit of good news is that it does not look as if the large spent fuel pond at the non working (at the time of the accident) Reactor 4 is having uncontrolled reactions.

At the moment.

A lot of the damage was caused by hydrogen explosions which in turn was caused by malfunctioning vents of the same type currently in use at many U.S. Nuclear Power Plants.

Japan Nuclear Watch, May 19: Critical Safety Vent Failures Could Happen Here Too

By: Scarecrow, Firedog Lake

As we’ve explained in previous Japan Watch posts, that sequence led inexorably to near total meltdown of the fuel core inside the reactor vessels at Units 1-3. (All of Unit 4’s fuel was in the storage pool, which presents problems.) TEPCO now concedes these meltdowns were likely total.

…

Although earlier expert analyses and TEPCO announcements suggested only partial meltdowns and varying levels of water covering parts of each reactor’s core, it now appears the cores were completely uncovered for some period early on - within the first hours or days - resulting in near total meltdown at each unit. That means the melted fuel is now puddled at the bottom of each reactor vessel, though it is thought (because of low temperatures) to be covered with whatever cooling water can be injected into each reactor vessel.

Earlier this week, they realized Unit 1’s vessel has one or more holes, leaks, allowing water and possibly melted fuel to leak out of the vessel onto the containment structure floor. The reports vary, but they suggest that tons of water, which they’ve been injecting into the core in desperate efforts to keep the core covered, have now found its way into the reactor building’s basement. Water from other units has leaked from other places, including adjacent turbine buildings and some has reached the ocean.

…

As we know, there were hydrogen-related explosions in all four units – that is, they waited too long, or, as they’re now discovering, the venting systems failed.

…

The Times report very helpfully reminds readers that all of the US reactors with the same GE design have essentially the same (new! improved!) venting systems as the ones that failed at Fukushima Daiichi. GE didn’t comment on the story.

So the next time someone tells you that, unlike those careless Japanese utilities and not too diligent regulators, we have much safer systems and our safety measures are “safer,” just remember this story, because it ain’t so.

The Times report to which Scarecrow refers is this one-

In Japan Reactor Failings, Danger Signs for the U.S.

By HIROKO TABUCHI, KEITH BRADSHER and MATTHEW L. WALD, The New York Times

Published: May 17, 2011

TOKYO – Emergency vents that American officials have said would prevent devastating hydrogen explosions at nuclear plants in the United States were put to the test in Japan – and failed to work, according to experts and officials with the company that operates the crippled Fukushima Daiichi plant.

The failure of the vents calls into question the safety of similar nuclear power plants in the United States and Japan. After the venting failed at the Fukushima plant, the hydrogen gas fueled explosions that spewed radioactive materials into the atmosphere, reaching levels about 10 percent of estimated emissions at Chernobyl, according to Japan’s nuclear regulatory agency.

…

Tokyo Electric in recent days has acknowledged that damage at the plant was worse than previously thought, with fuel rods most likely melting completely at Reactors 1, 2 and 3 in the early hours of the crisis, raising the danger of more catastrophic releases of radioactive materials. The company also said new evidence seemed to confirm that at Reactor No. 1, the pressure vessel, the last layer of protection, was broken and leaking radioactive water.

The improved venting system at the Fukushima plant was first mandated for use in the United States in the late 1980s as part of a “safety enhancement program” for boiling-water reactors that used the Mark I containment system, which had been designed by General Electric in the 1960s. Between 1998 and 2001, Tokyo Electric followed suit at Fukushima Daiichi, where five of six reactors use the Mark I design.

Most the damage at Reactor 4 was cased by an explosion in the vents that it SHARED with Reactor 3.

But there is also this follow up report, also from the Times–

NRC Finds Many U.S. Nuclear Plants Ill-Prepared to Handle Simultaneous Threats

By PETER BEHR of ClimateWire, The New York Times

Published: May 19, 2011

Something under one-third of the 104 U.S. reactors were found to have some vulnerabilities to extreme emergencies, according to the NRC, which is preparing a summary of its post-Fukushima findings.

…

At a time when the NRC and industry leaders are calling for a rigorous safety culture within the U.S. nuclear industry, the inspection findings raise questions about whether some plants were following the letter of requirements but not prepared for “unthinkable” events.

…

The plant owners’ responses to beyond design basis threats are usually voluntary. “We keep saying, ‘Oh, these are beyond basis events therefore we don’t’ get involved.’ We are happy that the industry responded. We look at it once. That’s it. In the future it’s up to them. I am really bothered by that.”

This piece contains details safety issues at a number of U.S. Nuclear Plants including Indian Point (NYC) and Millstone (Connecticut).

Juan Cole: Protest Backroom Deal to Extend Un-Patriot Act til 2015

There’s an action alert by a supporter of Rand Paul over at Firedoglake saying that an attempt will be made at 5 pm on Monday in the Senate to extend the misnamed ‘PATRIOT Act’ for four years. There will be an attempt to get unanimous consent for the extension, with just a motion to which there should be no objections.

Rand’s alert says,

   “The surveillance state’s ability to snoop through your business records, pry into your library book checkouts, monitor so-called “lone wolfs,” and spy on your personal communications through roving wiretaps will be extended until 2015, which “coincidentally” is not an election year.”

Here is a similarly urgent ACLU alert.

The vote is part of a deal between majority leader Harry Reid and his Republican colleagues to sidestep debate and rush the legislation through, which is becoming a worrisomely common procedure as the Democrats continue to abdicate their responsibilities to the Constitution, as Glenn Greenwald has elegantly explained.

Robert Kuttner: Beware Greeks Bearing Banks Beware Greeks Bearing Banks

After every financial debacle or war, there is a huge political struggle over whether creditors and financial speculators get to stand in the way of an economic recovery. When the creditors win, ordinary people who had nothing to do with the crisis are typically the victims. Today, the entire political elite is in the austerity camp, and those who argue that creditors should take some losses so that the rest of the economy can grow are mostly ignored.

This is the common theme to the issue of mortgage relief to spare American homeowners millions of foreclosures, the question of whether the US should sacrifice Medicare and Social Security on the altar of deficit reduction, and the punishment being visited upon small European economies such as Greece, Portugal and Ireland.

On this day in 1873, the Canadian Parliament establishes the North West Mounted Police, the forerunner of the Royal Canadian Mounted Police.

North-West Mounted Police

The RCMP has its beginnings in the North-West Mounted Police (NWMP). The police was established by an act of legislation from the Temporary North-West Council the first territorial government of the Northwest Territories. The Act was approved by the Government of Canada and established on May 23, 1873, by Queen Victoria, on the advice of her Canadian Prime Minister, John A. Macdonald, with the intent of bringing law and order to, and asserting sovereignty over, the Northwest Territories. The need was particularly urgent given reports of American whiskey traders, in particular those of Fort Whoop-Up, causing trouble in the region, culminating in the Cypress Hills Massacre. The new force was initially to be called the North West Mounted Rifles, but this proposal was rejected as sounding too militaristic in nature, which Macdonald feared would antagonize both aboriginals and Americans; however, the force was organized along the lines of a cavalry regiment in the British Army, and was to wear red uniforms.

The NWMP was modelled directly on the Royal Irish Constabulary, a civilian paramilitary armed police force with both mounted and foot elements under the authority of what was then the United Kingdom of Great Britain and Ireland. First NWMP commissioner, Colonel George Arthur French visited Ireland to learn its methods.

The initial force, commanded by Commissioner French, was assembled at Fort Dufferin, Manitoba. They departed on July 8, 1874, on a march to what is now Alberta.

The group comprised 22 officers, 287 men – called constables and sub-constables – 310 horses, 67 wagons, 114 ox-carts, 18 yoke of oxen, 50 cows and 40 calves. A pictorial account of the journey was recorded in the diary of Henri Julien, an artist from the Canadian Illustrated News, who accompanied the expedition.

Their destination was Fort Whoop-Up, a notorious whiskey trading post located at the junction of the Belly and Oldman Rivers. Upon arrival at Whoop-Up and finding it abandoned the troop continued a few miles west and established headquarters on an island in the Oldman, naming it Fort MacLeod.

Historians have theorized that failure of the 1874 March West would not have completely ended the Canadian federal government’s vision of settling the country’s western plains, but could have delayed it for many years. It could also have encouraged the Canadian Pacific Railway to seek a more northerly route for its transcontinental railway that went through the well-mapped and partially settled valley of the North Saskatchewan River, touching on Prince Albert, Battleford and Edmonton, and through the Yellowhead Pass, as originally proposed by Sandford Fleming. This would have offered no economic justification for the existence of cities like Brandon, Regina, Moose Jaw, Swift Current, Medicine Hat, and Calgary, which could, in turn, have tempted American expansionists to make a play for the flat, empty southern regions of the Canadian prairies.

The NWMP’s early activities included containing the whiskey trade and enforcing agreements with the First Nations peoples; to that end, the commanding officer of the force arranged to be sworn in as a justice of the peace, which allowed for magisterial authority within the Mounties’ jurisdiction. In the early years, the force’s dedication to enforcing the law on behalf of the First Nations peoples impressed the latter enough to encourage good relations between them and the Crown. In the summer of 1876, Sitting Bull and thousands of Sioux fled from the US Army towards what is now southern Saskatchewan, and James Morrow Walsh of the NWMP was charged with maintaining control in the large Sioux settlement at Wood Mountain. Walsh and Sitting Bull became good friends, and the peace at Wood Mountain was maintained. In 1885, the NWMP helped to quell the North-West Rebellion led by Louis Riel. They suffered particularly heavy losses during the Battle of Duck Lake, but saw little other active combat.
