. REPORT ON BODEGA BAY ATOMIC PARK - UlriT NO.1
Dear Dr. Seaborg:
J At its fifty-fifth meeting 'on May 7-9,1%4 at Argonne, Illinois, and at its fifty-eighth meeting on October 7-10,1%4, the Advisory Com-mittee on Reactor Safeguards again considered the proposal of Pacific Gas & Electric. Company to construct and operate a 1008 IG(t) bofling water reactor on Bodega Head north of San Francisco, California. The Comittee had the benefit of oral discussion with representatives of the applicant and its consultants, with the AEC Regulatory Staff and its consultants, including staff members of the U. S. Geological Survey (USGS) and the U. S. Coast and Goodetic Survey (USC&GS) and of the reports cited below. Subcon:mittee meetings were held July 31, 1%2'and March 20,1%3 and members of the Co=aittee again visited the excavated site on June 3,1%h. Numerous information meetings vere held with the applicant, the AEC Regulatory Staff, and with consultants.
l This proposal had been considered at the Committee s forty-seventh 2necting and reported on in its letter of April 18,1%3 which stated:
" Tentative exploration indicates that the reactor and turbine buildings vill not be located on an active fault line. The Committee believes that if this point is established, the design criteria for the plant are adequate from the standpoint of hazards associated with earthquakes. Careful examination of the quartz-diorite 1ock below should be nude during building excavution, to confirm this point. Furthermore, the Committee suggests that, during design, careful attention should be given t.o the ability of emergency shutdown systema to operate properly during and subsequent to violent earth shocks, and to the stress effects that might be introduced because the reactor building and the turbine building are to be anchored in different geological forcations. The need for earthquake-induced shutdown und isolation of the prin.ary system can be considered at a later ticie."

Att #1 - G-247 i
-Honorable Glenn T. Seaborc October 20, 1964 of testing or other experimental verification of structural design features associated with earthquake protection; provisions to assure adequate cooling water in case of damge to normal and emergency supply systems; core behavior during earthquakes; design and tests of critical plant components such as instrumentation, isolation valves, and control rod operating mechanicus to withstand earthquake damage; additional considerations whieb may be needed if circonium clad fuel is to be used.
The Committee recognizes that the applicant has accepted very conserva-tive values for earth chear movement, earthquake magnitudes, and tsunami heights as design criteria. These criteria should not be con-strued as precedents for use elsewhere.
1 With due consideration being given to the items discussed above, the Advisory Committee on Reactor Safeguards is of the opinion that the power reactor facility as proposed may be constructed at this site with reasonable assurance that it may be operated without undue hazard to the health and safety of the public.
Sincerely yours, I
