U.S. NUCLEAR REGULATORY COMMISSION OFFICr. OF INSPECTION AND ENFORCEMENT REGION III June 7, 1979 '
IE Information Notice No. 79-15 DEFICIENT PROCEDURES Summary On June 2,1979, at Arkansas Nuclear One - Unit 1, while observing conditions in the control room, an NRC inspector discovered an operational deficiency that could have resulted in the emergency feedwater system remaiaing isolated during subsequent power operation.
Description of Circumstances On June 2 while Arkansas Nuclear One - Unit I was preparing for startup, an NRC inspector in the control room found that during a surveillance test of the main feedwater check valves, the controls of the emergency feed-water 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 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 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 Arkansas 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 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.
