20555 June 7, 1979 IE Information Notice flo. 79-15 DEFICIENT PROCEDURES Summary On June 2,1979, at Arkansas Nuclear One - Unit 1, while observinq conditions in the control room, an ilRC inspector discovered an operational deficiency that could have resulted in the emergency feedwater system remaining isolated durino subsequent power operation.
Dascription of Circumstances On June 2 while Arkansas fluclear One - Unit I was preparing for startup, an tiRC inspector in the control room found that during a surveillance test of the nain feedwater check valves, the controls of the emergency feed-water system were positioned so that the system cculd not automatically respond if needed. The NRC inspector found that the test procedure beino used by the licensed operators did not include, as it should have, instruc-tions either to bypass the eneraency 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 system automatically. Lacking a procedural requirement to re-turn the system to normal, there was no assurance that emercency feedwater would be provided automatically if needed.
Following the Three Mile Island accident, the flRC required that operators be trained to initiate pronptly the emergency feedwater system manually if it does not come on automatically. Thus, while no immediate safety hazard existed at the Arkansas Unit 1 plant because of the inproper action, the fiRC staff is concerned about the potential safety hazard of leaving the emergency feedwater system in the bypassed condition, about the possibility 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 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 perating procedures, the adequacy of existing procedures, and until there ' '-
from those procedures.
