--Despite the projection by its own safety engineers that the older assumptions might be mistaken, Tokyo Electric was not breaking any Japanese nuclear safety regulation by its failure to use its new research to fortify Fukushima Daiichi, --
Är inte det ovan ett exempel på att det är fundamentalt svårt att få detta system att fungera? Med system menar jag i detta fall att låta privata företag driva extremt riskfylld verksamhet och tro att företaget och reglerande myndigheter kommer att ta tillräckligt ansvar för att undvika att allmänhet och miljö kommer till skada.

--In fact, Japan's NSC had concluded in 1992 that it was important for nuclear plant operators to have access to key gauges and instruments even in the kind of crisis that had not happened then. But it left plans on how to implement that policy entirely to the plant operators.
In the Fukushima accident, most meters and gauges were taken out by the loss of power in the early days of the crisis.
That left a pair of workers in a white Prius to race into the plant to get radiation readings with a handheld device in the early days of the crisis, according to Tokyo Electric.
They could have used robots to go in.
Immediately after the tsunami, a French firm with nuclear expertise shipped robots for use in Fukushima, a European nuclear expert said. The robots are built to withstand high radiation.
But Japan, arguably the country with the most advanced robotics industry, stopped them from arriving in Fukishima, saying such help could only come through government channels, said the expert who asked not to be identified so as not to appear critical of Japan in a moment of crisis.
