REQUEST FOR ADDITIONAL INFORMATION (RAI)

PILGRIM NUCLEAR POWER STATION. UNIT 1 UNRESOLVED SAFETY ISSUE (USI) A-46 The NRC has reviewed Boston Edison Company's (BECo) submittal dated September 30,1996 and determined that additional information regarding operator actions as specified in the report are needed to complete the review. Please respond to the following questions:

a. Describe what reviews were performed to determine if any local operator actions, required to safely shutdown the reactor (i.e., implement the safe shutdown equipment list (SSEL)),

could be affected by potentially adverse environmental conditions (such as loss of lighting, excessive heat or humidity, or in-plant barriers) resulting from the seismic event. Describe how staffing was evaluatec:. Describe the reviews which were conducted to ensure operators have adequate time and resources to respond to such events.

b. As part of BECo's review, were any control room structures identified which could impact the operators ability to respond to the seismic event? Such items might include but are not limited to: MCR ceiling tiles, non-bolted cabinets, and non-restrained pieces of equipment (i.e., computer keyboards, monitors, stands, printers, etc.). Describe how each of these potential sources of interactions was evaluated and provide the schedule for implementation of the final resolutions.

c. Describe what reviews were performed to determine if any local operator actions were required to reposition " bad actor relays." For any such activities describe how adverse environmental conditions (such as loss of lighting, excessive heat or humidity, or in-plant barriers) resulting from the seismic event were analyzed and dispositioned. Describe how staffing was evaluated. Describe the reviews which were conducted to ensure operators have adequate time and resources to respond to such events.

d. Describe which of the operator actions associated with resetting SSEL equipment affected by postulated relay chatter are considered to be routine and consistent with the skill of the craft. If not considered skill of the craft, what training and operational aids were developed to ensure that operators will perform tha actions required to reset affected equipment?

e. Assume the alarms associated with " bad actor relays" are expected to annunciate during the seismic event. Do the operators have to respond to those annunciators and review the annunciator response procedures associated with them for potential action? How would those additional actions impact the operators ability to implement the Normal, Abnormal, and Emergency Operating Procedures required to place the reactor in a safe shutdown '

condition?

f. To the extent that Normal, Abnormal, and Emergency Operating Procedures were modified to provide the plant staff with additional guidance on mitigating the A-46 Seismic Event, describe what training was required and provided to the licensed operators, non-licensed operators, and other plant staff required to respond to such events.
