20555 June 7, 1979 IE Information Notice No. 79-15 EFICIENT PROCEDURES Sum =a"y On June 2,1979, at Arkansas Nuclear One - Unit 1, while observing conditions in the control room, an NRC inspector 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 starty an NRC inspector in the control roo fouad that during a surveillance test of the main feedwater check valves, the controls of the e=ergency feed-water system were positioned so that the syste= could not automatically respond if needed. The NRC inspector found that the test procedure being used by the licensed operators did not include, as it should have, instruc-tions either to bypass the emergency feedwater system or to return it to normal. The plant operators, without approved procedures covering this aspect of the test, bypassed the controls that would have started the feedwater syste= automatically. Lacking a procedural require =ent to re-turn the system to normal, there was no assurance that =ergency feedwater would be provided automatically if needed.
Following the Three Mile Island accident, the NRC required that operators be trained to initiate promptly the e=argency feedwater systec manually if it does not coce on automatically. Thus, while no ic=ediate safety hazard existed at the Arkansas Unit 1 plant because of the improper action, the NRC staff is concerned about the potential safety hazard of leaving the emergency feedwater sy n.em in the bypassed condition, about the possibility that other procedures at the Arkansas plant may be deficient and about th: fact that the operators deviated fro: procedures in perforcing the surveillance test.
Arkansas Power and Light Co=pany has returned the plant to cold shutdown.
The June 2, 1979, NRC Order confirmed the requirement for a cold shutdown until the Commission staff is satisfied with the utility's method of con-trolling the development of op W
'r procedures, and until there is DUPLICATE DOCUMENT from those procedures.
