20555 June 7, 1979 lE Information Notice No. 79-15 EFICIENT PROCEDLEES Sur:=ary On Jane 2, 1979, at Arkansas Nuclear One - Unit I, while observinF conditions in the control room, an NRC inspector discovered an operational deficiency that could have resulted in the emergency feedwater system remaining isolated daring subsequent power operation.
Description of Circunstances On June 2 vhile Arkansas Nuclear One - Unit I was preparing for startup, an NRC insputor in the control room found that during a surveillance test of the main feedwater check valves, the controls of the emergency feed-rater system were positioned so that the system 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 coverf ug this aspect of the test, byp.ssed th ontrols that would have started the feedwater system automatically. Lacking a procedural requirement to re-turn the system 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 promptly the emergency feedwater system manually if it does not come on automatically. Thus, while no immediate safety hazard existed at the Arkansar Unit 1 plant because of the improper action, the NRC staff is concerned about the potential safety hazard of leaving the emergency feedwater system in the bypassed cond! tion, about the possibility and about that other procedures at the Arkansas plant may be deficient the operators deviated from procedures in performing the the fact that surveillance test.
Arkansas Power and Light company has returned the plant to cold shutdown.
for a cold shutdown The June 2, 1979, NRC Order confirmed the req frement until the Coc:=ission staf f isatisfgdgth the util'ty's method of con- - ~
trolling the development of o DUPLICATE DOCUMENT procedures, and until there i from those procedures.
