One of the things they couldnt get was insurance following that crash?No, I dont believe thats

Theres been a (actor) in fact the industrys self-insuringAnchorman: Dave: LISTENING第40页L-B-L.1 Script1.3and a structure that the government puts in place, that really has a model system, which essentially has no fault.

59、bill, its very interesting that the nuclear power industry, after half a century of governments support, still wants subsidies.
