ENCLOSURE SEQUOYAH hUCLEAR PLANT UNIT 1 RESPONSE TO INFRACTION 327/79-46-01 Description As required by 10 CFR 50 Appendix B, Criterion V, activities affecting qualify shall be accomplished in accordance with documented instructions.
The licensees accepted QA Program, FSAR Section 17.lA.5 states that activities affecting quality are prescribed by documented instructions in the form of drawings, specifications, and procedures.
Administrative Instruction AI-9, Temporary Alterations, which provrues instructions for implementing this requirement, states that alterations will be properly documented and approved.
Contrary to the above, on August 31, 1979, a temporary alteration was identified on the centrol switch for FCV-30-8, a safety related containment purge isolation valve, which met none of the approval and documentation requirements of Administrative Instruction AI-9.
Corrective Action Taken and Results Achieved An operator had secured the control switch for FCV-30-8 in the open position by attaching a rabber band to the switch handle and an adjacent protrusion on the control panel.
This had been done to allow purging of velding and burning smoke from the containment building during a time that an isolation signal was in effect because of incomplete work in the isolation circuitry.
This incident did not create a radiation safety problem since there was no fuel in the reactor.
The shift engineer placed the control switch in its normal position upon becoming aware of the alteration and informed the persons involved that this action constituted an alteration of the control circuit and required issuing a temporary alteration form.
Action Taken to Avoid Further Noncompliance The operations group was informed of the incident.
The importance of complying with temporary alteration instructions has been discussed with operations employees.
The operator requalification program also provides periodic review of procedures addressing temporary alterations.
Date When Full Compliance Will Be Achieved We are now in full compliance.
