TOPICS FOR PLANT VISITS IN SUPPORT OF 01-143, CHILLED WATER SYSTEMS AND ROOM COOLING PURPOSE OF VISIT Collect Information needed to determine the temperature rises following lose of room cooling In rooms containing safety-related equipment and sensitivity of components to failures at high temperatures.
GENERAL INFORMATION REQUIREMENTS thermal loads In rooms containing safety-related equipment from operation of the equipment and, in some rooms, from piping systems containing heated water.
capabilities of the safety-related equipment to withstand relatively high temperatures possible actions that could be taken to respond to losses of room cooling, Including actions to restore or supplement cooling in these rooms SPECIFIC INFORMATION NEEDED Room Coler Systein Design and Operation general flow diagram for room cooler system(s), including cooling water source (e.g., cooled directly by service water or plant includes Intermediate chilled water cooling loop between service water system and room coolers), list of safety-related rooms requiring room cooling, and overall system flow rates and heat removal capacity(les); operating procedures to cope with loss of room cooling.
Auxiliary Building Layout Information description and dimensions of ECOS pump rooms, control room, electrical switchgear rooms, battery rooms, and diesel generator rooms; capacities of room coolers provided In these rooms; assessments of heat generation rates from equipment and piping systems contained In these rooms; VItal Equipment Information location and equipment qualification Information (Appendix R and environmental qualification) on all ECCS equipment in rooms requiring room cooling, Including; pumps, valves, electrical power supplies, control circuits, electrical cabinets, etc.
NOTE: For most of this Information, it should be suffclient for the utility representative to simply provide for our review the environmental qualfIcation and Appendix R Information, This should minimize the Inconvenience to utility staff resources. A relatively brief tour of the appropriate auxiliaty building rooms should be suffclent for us to gather the needed room layout data.
