#Fukushima I Nuke Plant: Reactor 1's Containment Vessel (Dry Well) Measured 100 Sievert, Later Back to 6.83 Sievert

Nuclear and Industrial Safety Agency has said in the press conference at 7:00PM on April 8 that it may have been a faulty measurement.

This is from the plant parameters as of 6:00AM JST 4/8/2011:

D/W [dry well] 1.00 x 10^2 Sv/h [That's 100 sievert/hour.]
(as of 4/8 12:00AM)

So, right after the April 7 aftershock, it measured 100 sievert/hour.

But not to worry. The plant parameters as of 4:00PM JST 4/8/2011:

D/W 6.83 x 10^1 Sv/h [6.83 sievert/hour.]
(as of 4/8 1:00PM)

The radiation level of the dry well of the Reactor 1 Container Vessel has been rather high, and fluctuating, indicating that the reactor is far from stable.

I will let you know if I hear more squeak from NISA.

thanks, Simon. I posted that on my Japanese blog. When the dairy farmers and berry farmers and vegetable farmers of California sue TEPCO and the Japanese government, their budget for "reconstruction" will probably go 10-fold..

Increasing number of Japanese readers have started to come to my Japanese-language blog. They say there's hardly any credible info in Japan.

Well I think everybody is going to get screwed to a degree with language like this that will probably govern international compensation:

"Liability is Limited in Amount: Governments’ desire to encourage the development of the nuclear industry by relieving nuclear operators of the burden of potentially ruinous liability claims in the event of a nuclear accident, led them to adopt a principle which limits the amount of compensation payable to victims by a nuclear operator in the event of an accident for which it is liable. Without it, nuclear operators would be exposed to unlimited liability, meaning that once their available insurance coverage for this risk is exhausted, they would have to resort to their own assets to pay nuclear damage compensation which could, in turn, lead them into bankruptcy.5 This principle is, so to speak, the quid pro quo for the benefits to victims of the imposition of strict and exclusive liability upon a nuclear operator. Thus, even if the amount of damage suffered as a result of a nuclear accident exceeds the specified amount of liability imposed upon an operator, that operator will not be required to provide any further compensation.6
(4. This is contrary to the rules of ordinary tort law)"

"Liability is Limited in Time: The providers of required financial security, primarily private insurers, have made it clear that the coverage which they provide must be limited in time, usually to not more than ten years from the date of the nuclear accident for both personal injury and property damage claims. Neither insurance companies nor nuclear operators can accept the prospect of remaining liable to pay compensation for nuclear damage for an indefinite or even an extended period of time after a nuclear accident. In addition, in most jurisdictions there is a “discovery rule” which, in addition to the time limit for instituting claims, requires claims to be filed within two or three years of the date upon which the victims discovered the damage for which compensation is claimed. In some cases, the state will assume the responsibility of paying compensation for damage suffered where claims are instituted beyond the specified limitation period."
