20555 June 7, 1979 IE Information Notice No. 79-15 EFICIENT PROCEDLTIS Summary On June 2,.1979, at Arkansas Nuclear Ore - Unit 1, while ouserving conditions in the control roor_, :n FRC inspeer% discovered an operational deficiency that could have resulted in the emergency feedwater system remaining isolated during subsequent power operation.
Description of Circumstances On June 2 while Arkansas Nuclear One - Unit I was preparing for startup, an NRC inspector in the control room found that during a surveillance test of the main feedwater check valves, the controls of the emergency feed-water system were positioned so that the system could not automatically respond if needed. The NRC inspecter found that the test procedure being used by the licensed operators did no: include, as it should have, instruc-tions either to bypass the e=ergency feedvater system or to return it to normal. The plant operators, witk ut approved procedures covering this aspect of the test, bypassed the wntrols that would have started the feedwater syste= automatically. Lacking a procedural requirement to re-turn the systen to normal, there was no assurance that emergency feedwater would be provided automatically if needed.
Following the Three Mile Island accident, the NRC required that operators be trained to initiate prc=ptly the emargency feedwater system manually if it does not come on automatically. Thus, while no ic=ediate safety hazard existed at the Arkansas Unit 1 plant because of tae improper action, the NRC staff is concerned about the potential safety hazard of leaving the emergency feedwater system in the bypassed condition, about the pessibility that other procedures at the Arkansas plant may be deficient and about the fact that the operators deviated from procedures in performing the surveillance test.
Arkansas Power and Light Company has returned tae plant to cold shutdown.
The June 2, 1979, NRC Order confirmed the require =ent for a cold shutdown until the Commission staff is satisfied with the utility's method of con-trolling the development of procedures, and until there DUPLICATE DOCUMENT from those procedures.
