ACRS Staff R. Fraley R. Wilcox j Understandingti were reached relative to PG&E's intended course of action as fonows:

! 1. Double isolation valves win be provided in au fluid carrying lines which penetrate the containment vessel [an and open into or constitute a part of the primary system.

The question of inclusion of strainers upstream of the main steam line iselation valves was left open pendir4 evaluation of new hazards which might be introduced as a result of the addition of the strainers.

2. A back-up.for the auxiliary feedwater pump as a high presdure core spray supply is to be provided.

J

3. The' containment dry well and its internals will be designed to' permit' initially a test of the dry wen and an its

. penetration at an air pressure. equal to the dry wen desi6n pressure. . Further, unless the application is amended by-an approved change, all of the dry well penetrations win be designed to permit testing of the penetrations to' fun' design pressure, at intervals, subsequent to initial operation.-

In a variety of ,:tatements, representatives of PG&E again expressed their confidence that the Bodega Head site is a satisfactory site for the construction of a nuclear power plc.nt. Mr. Mautz stated that he feels that the Bodega Head site is as good a site for the location of a nuclear power plant as could be found in the state of California. He further stated that he thought their consultants would concur

_ in this opinion.

j.i;q It was stated that PG&E are maintaining a continuing evaluation of the site's seismological characteristics as excavation progresses. Shallow site grading is in progress at present.

The contract for deep excavation (to El.(-)70 feet) is to be let in August and should be complete near the end of 1963 or early 19624 It was stated t, hat F2c.E would abandon the l

site if this excavation reveals the existence of significant fault lines having a length appreciably greater than the width of the eveavation at elevation (-)70 feet.
