SUBJECT:
DIABLO CANYON CONFORMANCE WITH BRANCH TECHNICAL POSITION RSB 5-1 REGARDING NATURAL CIRCULATION, BORON MIXING, AND COOLDOWN We have completed our review and evaluation of the Diablo Canyon Unit 1 natural circulation, boron mixing, and cooldown test as described in WCAP-11095 (Non-Proprietary) and WCAP-11096 (Proprietary) reports transmitted to us by your letter dated March 25, 1986.
We were assisted in our effort by our consultant,
'Brookhaven National Laboratory (BNL), who performed a simulation of the test utilizing only safety grade equipment.
Our evaluation is enclosed, including as an enclosure the BNL report.
As a result of our evaluation and the BNL evaluation we conclude that the basic objectives of the test performed at Unit I have been met.
We further conclude, that the test can be applied to Unit 2 and that both units meet the intent of our Branch Technical Position RSB 5-1, "Design Requirements of Residual Heat Removal System" for Class 2 plants.
The evaluation of this matter is, therefore, complete.
It is our understanding that other Westinghouse plants will rely on the Diablo Canyon test and will reference it regarding RSB 5-1.
As stated in our evaluation, because of certain differences between the Diablo Canyon units and other facilities, further information will be required from utilities for those facilities in order to justify application of the Diablo Canyon test to their plants.
We have informed Westinghouse and the Westinghouse Owners Group of this position.
Sincerely, 8703090344 870303 PDR ADOCN, 0SOO027S P
