OCT 01 Tri MEMORANDUM FOR:

Hans Schierling, Project Manager Licensing Branch No. 3 Division of Licensing FROM:

Gary M. Holahan, Chief Operating Reactors Assessment Branch

}

Division of Licensing

SUBJECT:

DIABLO CANYON SALP INPUT Your memorandum dated September 20, 1984 requested that ORAB provide Diablo Canyon SALP input under a subject area you titled Event Reporting.

You later clarified what specific infomation you were requesting so that we now understand the subject area of concern is the licensee's perfomance in their interaction with ORAB during our followup to significant operating events as opposed to their perfomance in complying with event reporting requirements.

During this evaluation period there have only been two events at Diablo Canyon requiring significant followup by ORAB. They include: flooding of the auxiliary building pipe tunnel due to a valve failure (11/83); and disabling of high pressure injection trains during re-fill of the BIT Tank (4/84).

These events occurred some time ago and the recollection by the ORAB personnel involved in the-licensee's perfomance during our followup is not very precise.

We do not recall any particular problems which cause the licensee's performance in this area to stand out one way or the other.

On this basis, we would have to rate Diablo Canyon as average.

We have not completed the SALP evaluation fom you provided because we do not believe we are in a position to support a femal rating of Categories 1, 2 or 3 without a better recollection of the facts involved.

If in the future you require a SALP input in this subject area from ORAB we recommend that you request the input while we are actively interacting with the licensee.
