DCIDSURE BELLEFONTE NUCLEAR PLANT UNIT 1 INFRACTION 78-16-03 DEVIATION FROM SITE COMMITMENT ,

Infraction 50-438/78-16-03 Deviation from Site Conmitment Criterion V of Appendix B to 10 CFR 50, as implemented by the PSAR, Paragraph 17.1.5, requires in part, " Activities affecting quality shall be prescribed by documented instructions, procedures, ...and shall be accomplished in accordance with these instructions, procedures,..."

TVA procedureQAP 2.07, Rev.1 (in eff ect in March 1976) required OC inspectors to be trained and certified for each QC procedure being

' utilized.

Contrary to the above requirements, the following item was observed:

On August 22, 1978, during inspection of quality records for Component  !

Cooling System Subassembly No. 0-KC-01-12, the inspector noticed a QC signoff was performed by an inspector who was not certified. Step 4 of the Manufacturer"s Installation Quality Plan, a signoff in accordance with TVA procedure QCP-10.9, was signed off on March 4,1976, by an inspector who was not certified to QCP-10.9 until April 13, 1976.

Assessment of Infraction The inspector was not certifibd at the time of the infraction; however, he was under direct supervision and receiving on-the-job training.

Transfer of heat numbers, which this signoff concerned, is an important step in material control but is a relatively simple operation which can be bandled without difficulty with a minimum of training, though it is recognized that an uncertified inspector should not be performing this signoff.

Corrective Action Taken and Results Achieved .

The subject action was reported on Quality Control Investigation Report No. 656. An investigation of the subject Manufacturer's Installation Quality Plan (M10P) revealed that the heat number, which the uncertified inspector had signed off as being transferred correctly, was also recorded on the MlQP at the time of material issue and again on the welding record which was attached to the M10P. Checking materiel certifications for this particular material heat number determined the material to be acceptable for installation.

All'M10P's and Sequence Control Charts (SCC's) already on file are now being reviewed to ensure no others have been signed by uncertified inspectors. If these records are discovered to have been signed by y .

.mcertified inspectors, Quality Control Investigation Rnorts will be prepared to document and investigate the occurrence.

By the investigation described above for the specific instance, it was determined that the heat numbers were in fact transferred 3 correctly. For those instances discovered during the review of all .

other M10P's and SCC's, a similar investigation will be performed and the Quality Control' investigation Report for that particular instance will remain open until assurance can be obtained that the action signed i off by uncertified personnel was in fact perfonned correctly. l Steps Taken to Avoid Further Recurrence Originally, MlQP's and SCC's had not received detailed review, but have si_nce been added to the list of QA records requiring review. This formal review is now performed by the Quality Control and Records Unit before l these records are filed in the QA records vault. In addition, MEU inspection personnel have been instructed to verify their certification to the appropriate procedures prior to signoff of QA documents.

Date of Full Compliance Bellefonte Nuclear Plant will be in compliance with the established I requirements and the indicated investigation will be completed by November 15, 1978. ,
