Dear Hr. Crane:

HHartzman At the October 20, 1982 Commission meeting on Diablo Canyon the staff indicated that their consultant, Brookhaven National Laboratory (BNL), would be requested to perform a limited number of additional independent analyses.

In this regard.

a discussion of the BNL effort was provided in Enclosure 2 of SECY Paper 82-414 dated October 13, 1982.

Attached is a list of the drawings and data that have been identified as necessary to perform the intended analyses.

l<e request that you provide us with this infomation as soon as possible.

Please advise us promptly if any of the requested information can not be provided within 2 weeks after receipt of this letter.

The purpose of the BNL analyses are to provide the staff with additional insight as to the character of results obtainable by use of state-of-the-art analytical techniques without regard to methods or procedures previously approved in the licensing process for Diablo Canyon.

These analyses are therefore not intended as a substitute for the design and evaluation efforts now underway for the Diablo Canyon project; nor are they a substitute for the analytical-- efforts being performed by the Independent Design Verification Program (IDVP).

Our experience has

been, however, that such analyses often provide the bases for judgements that expedite the review process.
