Docket No. 50-323 Pacific Gas and Electric Company 77 Beale Street, Room 1451 San Francisco, California 94106 Attention:

Mr. J.

D. Shiffer, Vice President Nuclear Power Generation Gentlemen:

Subject:

Special NRC Inspection of Diablo Canyon Unit 2 This refers to a special inspection conducted by Mr.

P.

P.

Narbut during the periods of August 15, September 10 and 11, and October 12-13 and 30, 1987.

This inspection examined your activities as authorized by License No.

DPR-82.

At the conclusion of the inspection, discussions of the technical findings were held with Mr. J.

D.

Townsend and members of your staff.

The subject was also discussed as part of the agenda at the management conference held on October 30, 1987, in the Region V office in Walnut Creek.

Areas examined during this inspection were described in the enclosed inspection report.

Within these areas, the inspection consisted of selective examinations of procedures and representative records, interviews with personnel, and observations by the inspector.

Based on the results of this inspection, it appears that two of your activities were not conducted in full compliance with NRC requirements, as set forth in the Notice of Violation, enclosed herewith as Appendix A.

Your response to this notice is to be submitted in accordance with the provisions of 10 CFR 2.201 as stated in Appendix A, Notice of Violation.

Although identified by your staff, the improper heating of the RHR pipe is of particular concern to the NRC because of the series of administrative shortcomings associated with this event.

Several instances of failure to follow plant procedures occurred during the improperly performed maintenance activity and are considered to have been a primary contributor.

Further, a

maintenance engineer, without management concurrence, elected to have work performed beyond the scope of his authority on a safety-related component which usurped your management staffs'erogative to evaluate and review the situation.

Our review also indicated that the engineering design bases from plant construction for pipe cold springing were not incorporated in a current maintenance procedure.

This may indicate that additional engineering design bases from plant construction may not have been transferred into appropriate operations-phase, maintenance procedures.

Finally, our inspection followup concluded that your corrective actions were not sufficiently comprehensive to fully address the weaknesses identified.

We recognize that you have several initiatives ongoing in the above areas and suggest that you review those initiatives to assure they are sufficiently broad to prevent recurrence.

NOV 23 l987 This inspection was performed in adjunct to an Office of Investigations inquiry into the matter of improperly controlled flame heating of a Unit 2 Residual Heat Removal (RHR) pipe which occurred on May 5, 1987.

This inquiry concluded that the flame heating event was a willful act.

However the intent was not to circumvent procedures with a specific purpose of wrongdoing.

The NRC's Office of Investigation's inquiry into this matter has been closed.

In accordance with 10 CFR 2.890(a),

a copy of this letter and the enclosures will be placed in the NRC Public Document Room.

The responses directed by this letter are not subject to the clearance procedures of the Office of Management and Budget as required by the Paperwork Reduction Act of 1980, PL 96-511.

Should you have any questions concerning this inspection, we would be please to discuss them with you.

Sincerely,

~
