9 Attachment page 1 RESPONSE TO NOTICE OF VIOLATION ITEMS REPORTED IN IE REPORT 338/ 79-45 AND 339/79-54 A. NRC COMMENT As required by Unit 1 Technical Specification Table 3.3-3, Iten 1. e , three steam pressure channels per operating loop are required to be operable in modes 1, 2 and 3 except as permitted by Action Statement 14. Action Sta teme nt 14 states that with the number of OPERABLE Channels one less than the Total Number of Giannels, operation nay proceed until performance of the next required CIIANNEL FUNCTIONAL TEST (monthly), provided the inoperable channel is placed in the tripped condition within one hour.

Contrary to the above, main steam pressure transmitters for loop A, Channel IV (PT-1476) and loop C, Channel IV (PT-1497) were inope rable throughout the first cycle of Unit 1 because their sensing lines had been swapped. This was apparently done durir.g a cutting and rewelding process under the Rework Control Program (RCF 1-350) in July, 1977.

This is an infraction.

RESPONSE

The infraction stated above is correct.

(1) Corrective steps which have been taken and the results achieved:

As stated in the Notice above, the sensing lines for PT.1476 (loop A) and PT-1497 (loop C) were determined to be crossed by MR N 179 1016 1510 completed October 16. This was determined to be a reportable occurrence and LER 79-14201T-0 was submitted. Riintenance Report N1-79-1108-1640 was submitted to have the sensing lines reconnected to the proper transmitters. This work uas comple ted on 11/30/79.

In order to verify that these ESF sensing lines were properly connected to the proper transmitters, 1-MP-P-PROC-04 was perfo rmed. During this investigation it was determined that sensing lines for the Loop A CCS Flow transmitters FT-1414 and FT-1415 were on different pipe tap locations on the proper loop than that which appeared on the piping drawings. This was not a problem since the proper function was being performed by the equipment. The se lines were changed to comply with plant drawings. No other problems were discovered and all the ESF System Sensing line piping has been verified to be correctly connected.

(2) Corrective steps which will be taken to avoid further noncompliance:

Since this is considered to be an isolated incident which occurred during construction of the unit, no further corrective action is required. Additionally, Unit 2 is being reviewed.

(3) The date when full compliance will be achieved:

Full compliance was achieved on 11/30/79 when the stean line pressure sensing lines were correctly installed. The Unit 2 review will be completed prior to issuance of an Operating License for Unit 2.

Attachment page 2 B. NRC COMMENT As required by Unit 1 Technical Specification 6.10. 2.h, records of training and qualification for current plant staf f nenbers are to be maintained as life time records. The Nuclear Power Station Quality Assurance Progran - Operations Phase (VEP-1-3A) commit to retention of such records in accordance with ANSI N45. 2-9, 1974. This document requires a special storage repository or duplicate records systems.

Contrary to the above, records of training received by nechanical and electrical maintenance employees as part of the Mechanic Development Programs are not maintained as required. These records are not retained at the plant site and apparently one copy is maintained in the VEPCO corporate offices.

This is a Deficiency.

RESPONSE

The Deficiency stated above is correct.

(2) Corrective steps which have been taken and the results achieved:

Due to the amount of records involved, no corrective steps have been taken, thus far, to comply with stated requirements.

(2) Corrective steps which will be taken to avoid further noncompliance:

Beginning January 1, 1980, a copy of the original of the applicable records will be retained and kept in an approved location. Appro-priate documentation for electrical and mechanical maintenance employees who are employed prior to January 1, 1980 vill be re-trieved and stored at North Anna Power Station for those employees that are in the respective development programs and working at the station on January 1, 1980.

(3) The date when full compliance will be achieved :

Full compliance will be achieved March 31, 1980.
