@elainekirk : the japanese people and their government are firmly in the hands of the nuke industry.

@you, I must amend Goering did not phrase the idea quite like I did. He answered after being asked in an interview what secrets the Nazis used to get the German people on their side: "The masses are brainless. You just fill their heads with fear and promise them security, and they shall eat from your hands!"

I must cite another long passage on the implementation of hardened vents. This is quoted from a petition filed with the NRC by BeyondNuclear on April 13 ( www.google.com ):
“B. Of the twenty one (21) GE BWR Mark l with the free standing steel primary containment a number of the units currently rely upon a “hardened vent system” also known as the Direct Torus Vent System (DTVS) where the control room can now deliberately vent the recognized undersized and vulnerable Mark I pressure suppression containment temporarily under severe accident conditions in order to prevent the containment from over-pressurizing and/or internally venting explosive environments that would likely cause the permanent rupture and breach of containment and result in a sustained uncontrolled release of significant amounts of harmful radioactivity. These back fits were pre-approved by NRC Generic Letter 89-16 “Installation of Hardened Wetwell Vent System,” September 1, 1989.
The NRC staff pre-approval was provided as incentive to the Mark I operators to voluntarily install “hardened vent systems” also known as the Direct Torus Vent System (DTVS) to the pressure suppression pool component also known as the “torus.” The DTVS is an 8-inch hardened steel line that runs from the Mark I suppression pool chamber or torus, bypasses the BWR charcoal bed radiation filtration system and connects directly to the three hundred (300) foot tall off gas ventilation stack. The DTVS design to bypass the radiation filtration system is essential to reduce back pressure on release through the experimental pipe system. The control room operates a butterfly valve in the pipe in conjunction with a 30 psi carbon rupture disc designed given the operator an option to temporarily defeat containment in order to assure long term containment integrity. It is the understanding of the Petitioner that a certain number of nuclear power plants operators may have installed the DTVS but subsequently either abandoned it or removed it while some number of operators did not follow-through with the installation of these hardened vents for on their containments. A complete and transparent review is necessary to determine which and why operators did and did not experiment with the hardened vent systems to mitigate potential severe accident consequences in Mark 1 containment systems.”

If true, this is frightening!

Hi Angie!

Friends of the Earth Challenges New AP1000 Nuclear Reactor Design
This reactor is the first new design in decades being considered for construction in the U.S. Though questions linger about the design’s safety, and even though the NRC has not conducted additional analysis in the wake of the Fukushima disaster in Japan, the NRC is sticking with an industry-backed fast-track licensing approach.
Nuclear engineer Arnie Gundersen and the staff of Fairewinds Associates analyzed the design of the AP1000 reactor and found many aspects lacking, as cataloged in the comments formally submitted to the NRC by Friends of the Earth. The comments state that claims made about the safety of the reactor’s containment structure “are not based upon sound scientific analysis and engineering review, but appear instead to be based upon the mythical dreaming of an aggressive industry and its captive regulator.”
According to the comments authored by Gundersen and Fairewinds, the passive cooling system of the AP1000, which lacks a robust containment shell, merits close scrutiny. The cooling of the 1.75-inch steel containment shell is dependent upon a vulnerable 800,000-gallon tank precariously perched on top of a vented “shield building,” a structure whose integrity has been questioned by even the lead NRC engineer in the design review. Fairewinds states: “This single source of cooling water perched atop the shield building is unique to the AP1000 design and Westinghouse’s reliance upon it creates a single point of vulnerability that has not been thoroughly evaluated by industry regulator NRC due to the rush to AP1000 certification and licensure.”

…and I quote from Sherrell. R. Greene's report with the title "Role of BWR Secondary Containments in Severe Accident Mitigation" last modified Mar. 23, 2011 ( www.sumofallfears.com ):
“One potential solution to the problems associated with use of existing containment venting systems is the installation of hardened filtered venting systems, such as the FILTRA system in use at the Barseback BWR plant in Sweden. While the Long Island Lighting Company had intended to install a similar filtered vent system at the Shoreham Plant, such systems have traditionally been viewed by U.S. utilities as having unacceptably low cost/benefit ratios.”

Evening all. So did anyone decide if that was Fukushima Di Ini?

And if you don't get to the story linked below, the brief summary is they found 33 pinhole leaks in the piping and also some bad seals etc, which led to the escape of radioactive gas into the plant and into the atmosphere. This might have happened because they hadn't inspected the piping or the connections since 1987... As in, 1987.

Kyodo English had the news advisory and and it is no longer there. I did a search on the Japanese version of the news advisory in Chrome.
