Dear Mr. Goldblatt:
I am responding to your letter of July 1,1981 to the Director, Office of Technical Information and Document Control.
In this letter you express concern that the environmental impact statements that were sent to you (llVREG-0534, 0769, and 0779) did not contain any discussion of the seismicity at the nuclear power plant sites.
It is the current practice of the fluclear Regulatory Cocsaission to not include a discussion of site seismicity in our environmental impact statements. This is because the statements are intended to be an analysis of the impact of the construction and operation of a nuclear power plant on the external environment.
Our analysis indicates that the construction of nuclear power plants does not affect the seismicity of the power plant site except when a cooling lake must be constructed. In these circumstances, seismic activity might be observed during the filliin or emptying of the cooling lake. This effect is caJsed primarily by the deformation of the soil and rock structure underneath the lake due to the weight of the water and is a cocraon occurrence in areac surrounding reservoirs of all types. When such an effect is anticipated, it is now our practice to discuss this effect in the environmental impact statement.
On the other hand, we do include a detailed analysis of site seismicity and the manner in which the nuclear plant is designed to accommodate this seismic activity in the safety evaluation reports for the individual plants. We are enclosing the safety evaluation reports for Summer, Fermi and Waterford. Your perusal of the sections of these reports that deal with site seismicity and plant seismic design may alleviata your concerns.
