REQUEST FOR ADDITIONAL INFORMATION REGARDING THE LICENSEE'S ANALYSIS ON THE VERIFICATION OF SEISMIC ADEQUACY OF MECHANICAL AND ELECTRICAL EQUIPMENT IN OPERATING REACTORS.

QUAD CITIES NUCLEAR POWER STATION. UNITS 1 AND 2 DOCKET NOS. 50-254 AND 50-2f.h The Human Factors Assessment Branch has completed its review of the licensee's submittal dated June 28,1996. The staff requires additionalinformation regarding operator actions specified in the report in order to make a safety determination.

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 (suen as loss of lighting, excessive heat or humidity, or in-plant barriers) resulting from the seismic event. Describe how staffing was evaluated and describe the reviews which were conducted to ensure operators had adequate time and resources to respond to such events.

h. As part of the I!censee's review, were any control room structures which eculd impact the operator's ability to respond to the seismic event identified? Such items might include, but are not limited to: main control room 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 has been evaluated and describe the schedule for implementation of the final resolutions. j
c. Describe what reviews were performed to determine if any local operator actions were required to reposition " bud 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 and describe the reviews which were conducted to ensure operators had adequate time and resources to respond to such events.

i

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 the operators will perform the 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 plant staff with additional guidance on mitigating the A-46 Seismic Event, ,

i describe what training was required and provided to the licensed operators, non-licensed operators, and other plant staff required to respond to such events.
