U.S. NUCLEAR REGULATORY COMMISSION OFFICE OF INSPECTION AND ENFORCEMENT REGION III June 7, 1979 '
IE Information Notice No. 79-15 DEFICIEM PROCEDURES si.- 2 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: remaining isclared during subsequent power operation.
Description 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 feedvater check valves, the contro.'.s of the emergency feed-water syste= were positioned so thi.: the system could not auto =atically 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 f eedvater syste= 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 syste= to normal, there was no assurance that e=ergency feedwater would be provided automatically if needed.
Following the Three Mile Island accident, the NRC required that operators be trained to initiate prc=ptly the emergency feedwater syste= canually if it does not come on auto =atically. Thus, while to 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 may be deficient and about the fact that the operaters deviated fro procedures in perfor=ing the surveillance test.
Arkansas Power and Light Co:pany has returned the plart to cold shutdown.
The June 2, 1979, NRC Order confir=ed the require =ent for a cold shutdown until the Co==ission staff is st**
