Subject:

Docket No. 50-361 l

San Onofre Nuclear Generating Station, Unit 2 In a letter from your office dated April 10, 1981 we l were requested to respond to a Notice of Violation resulting from inspections of San Onofre Unit 2 construction activities which took place during the period January 16 to February 13, 1981. The condition described by the Notice'of Violation in-volved failure to perform an adequate review and updating of a '

Startup Test Procedure prior to performing the test ,

I trust the attachment responds adequately to all aspects of the Notice of Violation. If you have any questions, or if we can provide additional information, please let me know. ,

RESPONSE TO NRC NOTICE OF VIDIATION DATED APRIL 10, 1981 San Onofre Nuclear Generating Station, Unit 2 Response to the oN tice of Violation is provided below. A statement of the condition as described by the notice is given for reference.

NOTICE OF VIOLATION Docket No. 50-361 As a result of an NRC inspection on January 16 to February 13, 1981, and in accordance with the Interim Enforcement Policy, 45 FR 66754 (October 7, 1980), the following violation was identified:

Appendix B of 10CFR50, Criterion V, states, in part, that, " Activities affecting quality shall be prescribed by documented instructions, procedures, or drawings, ... and shall be accomplished in accordance with these in-structions, procedures, or drawings."

Startup Test Instruction TI-2, Paragraph 5.2.2, states, in part, " Approx-imately 90 days prior to the scheduled test date ... the writing organiza-l tion will withdraw the test procedure from their files for update. This I update includes tF2 following: (b) Revising / rewriting the procedure to incorporate any known design changes."

Paragraph 5.2.3 of TI-2 states, in part, " Prior to performance of the test, a final review and update of the procedure is performed by the cognizant Startup Engineer as follows: (a) Check the procedure against the latest design documents listed in the reference section."

Contrary to the above, ' he inspector determined on February 4,1981, that Test Procedure 2 HA-102-01, Thermal Expansion, had not been updated to incorporate the latest design charges prior to the scheduled test date, nor had the cognizant Startup Engineer checked the procedure against the latest design documents. As a result of the licensee's failure to perform the required procedure reviews, approximately 30 thermal expansion measure-ments were not taken at the ambient temperature plateau and major revisions were required to the data sheets in test Appendices AA,10 K,10 M,10 0, 10 Q, 10 U, and 10 W. The 260 F plateau measurements were not complete and had to be repeated.

This is a Severity Level V violation (Supplement 1) .

RESPONSE

1. Corrective Steps Which Have Been Taken and Results Achieved The condition stat 3d in the N' o tice of Violation was identified in Corrective Action Request SE-F-0147, dated February 7,1981.

The failure to perform an adequate review and update of the test procedure prior to performance of testing has been addressed by the following actions.

a. A hold was placed on Hot Functional Testing at 26007, pending further evaluation of data. During the 4 day hold period a review of problems related to administration of the Thermal Expansion Test was conducted. These problems, which included the noncompliance described in the Notice of Violation, l

were identified in a series of Corrective Action Requests. It was determined that the discrepancies noted in the CAR's did not result from a lack of controls in the Startup program but rather from a failure to adequately implement the existing controls.

t

b. Test Procedure 2EA-102-01 was reviewed again against latest l effective design documents and appropriate Test Change Notices were isst ed. .

l l c. A stress engineer from the design group was added to each team taking thermal expansion data. This engineer was made responsible for providing technical advice and consultatien on data acquisition and reporting methods. Points were established in the procedure which direct the Test Engineer to obtain a review by the stress engineer.

d. All measurements at the 260 0F plateau which were added by the updating of the procedure were taken.

e. Thirty (30) measurements which were added by the procedure revision and which had not been taken during the original ambient temperature condition were taken in accordance with the revised procedure when the system returned to ambient temperature. Cer-

- tain measurements which had been taken at original ambient by the use of lanyards were not repeated on return to ambient because l

L lanyards had been removed inadvertently. A test Exception Report was initiated to dispositiun this omission.

2. Corrective Steps Which Will Be Taken The steps listed above have been taken and documented. These steps address remedial action such as updating of the procedure and repeating affected test steps. Corrective action to prevent recurrence has included replacement of involved personnel and training sessions for Startup Engineers. The effectiveness of.

these remedial and corrective actions will be monitored by

! Quality Assurance Organization. No further corrective steps are to be taken.

3. Date When Full Compliance Will Be Achieved Full compliance was achieved on March 28, 1981 when all nessure-ments required by the updated procedure had been taken and train-ing sessions had been completed for Startup Engineers.
