20555 June 7, 1979 IE Information Notice No. 79-15 EFICIENT PROCEDUFIS Su==ary On June 2,_1979, at Arkansas Nuclear One - Unit 1, while observing conditions in the control roo=, an NRC inspector discovered an operational deficiency water system remaining isolated that could have resulted in the energency fea during subsequent power operation.
Description of Circumstances On June 2 while Arkansas Nuclear One - Unit I was preparing for startup, an FRC inspector in the control room found 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 systec could not automatically respond if needed. The NEC inspector found that the test procedure being used by the licensed operators did not include, as it should have, instruc-tions either te 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 requirement to re-turn the system to normal, there was no assuran:e 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 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 f?edwater system in the typassed condition, about the possibility that other procedures at the Arkus-plant may be deficient and about the fact that the operators deviated fro = procedures in perforcing the surveillance test.
Arkansas Power and Light Company has returned the plant to cold shutdown.
The June 2, 1979, NRC Order confirmed *.he requirement for a cold shutdown until the Commission staff is.. 'Mm _
