DEFICIENT PROCEDURES Sm--a 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 emergency feedwater system remaining isclated during subsequent power operation.
Description of Circumstances On June 2 while Arkansas Nuclear One - Unit I was preparing fer startup, an NRC inspector in the control roc: found that during a surveillance test of the tain feedwater check valves, the controls of the emergency feed-water syster were positioned so that the systec could not automatically respond if needed.
The h7C inspector found that the test procedure being used by the licensed operators did not include, as it should have, instruc-tiens either to bypass the e=ergency feedwater systet 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= autocatically. Lacking a procedural requirement to re-turn the systet to nor al, 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 pro:ptly the emergency feedwater syste canually if it does not come on auto =atically. Thus, while no ic=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 emergency 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 operators deviated from procedures in perf ormin:; the surveillance test.
Arkansas Power and Light Co=pany has returned the plant to cold shutdown.
