1 Thank you for your recent letter regarding the Maine Yankee shut-f I am sorry not to have cnswered it sooner, but the acciden't at I
down.
That accident, Three 14ile Island has taken precedence over everything.
incidentally, would have been shown by both our probability calculations i
and those of the industry to be far less likely than the occurrence of a significant earthquake at one of the four plant sites in question.
The earthquake probabilities were on the order of one every two hur. dred to four hundred years (which amounts to one every fifty to one hundred years at one of the four sites). The calculations for radioactive
,j reldaces within the containment on the order of those experienced at Three Ilile Island were that they would occur not more often than once per thousand years of reactor operation.
I hope that the first optimistic indications from the ~ ecalculations r
If they at Itaine Yankee are borne out by the reviews now under uay.
are, I will do all that I can to get Itaine Yankee back into operation quickly.
