20555 June 7, 1979 IE Information Notice No. 79-15 DEFICIENT PROCEDURES Summary On June 2,1979, at Arkansas t'uclear One - Unit 1, while observing conditions in the control roca, an NRC inspector discovered an operational deficiency that could have resulted in the emergency feedwater system remaining isolated during subsequent power operation.
Description of Circunstances On June 2 while Arkansas Nuclear One - Unit I was preparing for startup, an NRC inspector in the control roon found that during a surveillance test of the rain feedwater check valves, the controls of the emergency feed-water system were positioned so that the system could not automatically respoad 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 bycass the eneraency feedwater system or to return it to nornal.
The plant operators, without approved procedures covering this aspect of the test, bypassed the controls that would have started the feedwater system autcmatically.
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 flile Island accident, the flRC required that operators t e trained to initiate pronptly 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 inproper 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.
Arkansas Power and Light Company has returned the plant to cold shutdown.
The June 2, 1979, NRC Order confirned the requirement for a cold shutdown until the Commission staff is satisfied with the utility's method of con-trolling the development of operating procedures, the 3dequacy of existing procedures, and until there is assurance that onerators will not__deviato frcm those procedures.
