Dear Senator D'Amato:
This. is in response to your letter of January 29, 1982 transmitting the concerns of. Mr Truman C. Whiteman of New York City with respect to the ability of nuclear power plants to resist major earthquakes. We share Mr. Whiteman's belief that seismic capacity for nuclear plants must be ensured.
Design and construction to provide adequate ea tWake resist-ance are major considerations in the comission licensing roiew process and inspection programs for all nuclear facilities.
The earthquakes which _ occurred recently on the east coast, a region not commonly known for.its earthquake activity, understandably caused anxiety.
However, serious damage due to earthquakes is usually due to the lack of specific design requirements for earthquake resistance. There have been very few reported failures of well engineered structures, residential, commercial or industrial, for which earthquake resistance was a specific design consideration as required by modern building codes. With regard to nuclear power plants current comission requirements for earthquake resistant design are more stringent and required methods of analysis more advanced than those required by the conventional building codes..
In addition, for plants which were designed, constructed and licensed to operate before the issuance of current comission requirements we have undertaken a Systematic Evaluation Program to, among other things, re-assess the seismic margins for these plants.
' For your information and possible transmittal to Mr. Whiteman, we are enclosing the following:-
1.
A description of the Systematic Evaluation Program from the U. S'.- Nuclear Regulatory Comission,1979 Annual Report to the Congress, pp. 114-115.
