Dear Mrs. Schlaff:
Thank you very much for your letter regarding Diablo Canyon. The recent Comission decision authorizing low-power testing and fuel -loading is only the first step in Comission review of this plant. Specifically, tne earthquake-related issues that distinguish Diablo Canyon from post other nuclear units have not yet been addressed in detail by the Comission.
They will be reviewed before operation above five percent power is authorized.
While it may have some symbolic importance, a decision to authorize icw-rower testing poses very little danger to the public. The power level is so low that the operators have more than ample 3ime to react to any problems in the plant, and the amount of radioactivity existing in t
the core does not begin to build up until the plant has operated for Quite a while.
Sincerely,
/
Peter A. Bradford Comissioner i
