U.S. STCLEAR REGULATORY C0511SSION OFFICE OF,INSFECTION AND ENFORCEMENT REGION III June 7, 1979 IE Infor ation Notice Sc. 79-15 Dr.FlCIE'.T PROCEDURES S c ry On June 2, 1979, at Arkansas Nuclear One - Unit 1, while observing conditions in the control roo=, an NRC inspector discovered an operational deficiency that could have resulted in the e=ergency feedwater syste re=aining isolated during subsequent power operation.
Descriptien of Circu= stances On June 2 while Arkansas Nuclear One - Unit I was preparing for startup, an NRC inspector in the control roo= found that during a surveillance test of the =ain feedwater check valves, the controls of the e=ergency feed-water systen were positioned so that the syste= could not auto =atically respend 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 e=ergency feedwater syste= or to return it to nor=al.
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 syste= to nor=al, there was no assurance that e=ergency feedwater would be provided automatically if needed.
Following the Three tiile Island accident, the NRC required that operators be trained to init.'. ate pro =ptly the e=ergency feedwater syste: =anually if it does not co=e on auto =atically. Thus, while no i==ediate safety hazard existed at the Arkansas Unit 1 plant because of the i= proper action, the NRC staff is concerned about the potential safety hazard of leaving the e=ergency feedwater syste= in the bypassed condition, about the possibility that other procedures at the Arkansas plant nay be deficient and about the fact that the eperators deviated from procedures in perfor=ing the surveillance test.
Arkansas Power and Light Cc=pany has returned the plant to cold shutdevn.
The June 2, 1979, NRC Order confir=ed the require =ent for a cold shutdown until the Co==1ssion s taf f is satisf f - %'" 9' * * ' ' - b-e" >
