2 December 4, 1992

• Failure to include two required check valves in the Palo Verde Inservice

Testing Programs, and failure to perform the required inservice testing.

• Failure to properly document and evaluate nonconforming conditions

identified during a check valve inspection and during a snubber inservice

inspection.

• Failure to perform check valve examinations required by procedure.

The weaknesses and violations identified during this inspection indicate a

lack of management oversight of the implementation of your check valve

program, particularly assurance of procedure compliance and updates of generic <

information. Both issues have been identified to you in previous NRC

inspection reports. Your recent responses to these problems indicate that you

understand them and that you are taking actions to correct them.

You are required to respond to this letter and should follow the instructions

specified in the enclosed Notice when preparing your response. In your

response, you should document the specific action taken and any additional

actions you plan to assure that all personnel know and understand your

expectations of procedural compliance. After reviewing your response to this

Notice, including your proposed corrective actions and the results of future

inspections, the NRC will determine whether further NRC enforcement action is

necessary to ensure compliance with NRC regulatory requirements.

The responses directed by this letter and the enclosed Notice are not subject

to the clearance procedures of the Office of Management and Budget as required

by the Paperwork Reduction Act of 1980, Pub. L. No.96-511. In accordance

with 10 CFR 2.790 of the NRC's, " Rules of Practice," a copy of this letter and

enclosure will be placed in the NRC Public Document Room.

Should you have any questions concerning this inspection, we will be pleased

to discuss them with you.

Sincerely,
