1 Dear Thank you for your recent letter regarding the IGine Yankee shut-I o.
doun.
I am sorry not to have answered it sooner, but the accident at Three liile Island has taken precedence over everything.
That accident, incidentally, would have been shown by both our probability calculations 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 vera on the order of one cvery two hundred to fot.r hundred years (uhich amounts to one every fif ty to one hundred years at one of the four sites).
The calculations for radioactive relJases within the containment on the ordcr of those experienced at Three !!ile Island were that they would occur not c. ore of ten than once per thousand years of reactor operation.
'e I hooe that the first optimistic indications from the recalculations y
at I aine Yankee are borne out by the reviews now under uay.
I f they ai e, I will do all that I can to get Imine Yankee back into tperation quickly.
L. '
Sincerely, g,pf
~
Peter A. Bradford Commissioner 1
