am pleased to respond to your letter of August 17, 1979 to the Presfdegt of the United States>>hfch was referred to me'for.reply.
In your letter, you expressed concern over the safety of the Diablo Canyon Nuclear Power Plant in view, of its proximity to an active earthquake fault.
Me assume that you are referring to theIIHosgri Fault >>hich is located approxi-mately 3 1/2 mlles offshore of the Diab}o Canyon site.
The.Hosgri Fault IIas discovered 4n 1971>>ell after the construction of the plant was started.
This fault is located 3 1/2 mf les offshore ft'.om the Diablo Canyon plant site.
As a result of this discovery, an intensive investigation of the Hosgri Fault >>as undertaken by the Pacific Gas 5 Electric Company, the U. S. Geological Survey (USGS) and the Nuclear Regulatory.Coomission/e Comprehensive public hearings on this matter >>ere held by the Atomic Safety and Licensing Board over about, a two-month period.
Transcript of these
- hearings, delineating the views of various seismic experts, on thfs issue, fs avafT'abIo in the Public Document Room >>hich is located in the California Polytechnic State University Library in San Luis Obispo, California.
These hearings were completed ort~February 15, 1979 and a Partial Initial Decision rendered by the,Atomic Safety, arid Licensing Board on September 27, 1979, >>hich included a favorable finding oq the seismic design adequacy of the Diablo Canyon plants.
A copy of the Partial'nitial Decision, which is an excellent synopsis of the seismic sftuatiog at Diablo Canyon, is also available in the above cited Public Document Roon.
I trust that the above information is useful in assessing the concet"ns you raised in your letter.
