ENCLOSURE 1 INSTRUMENTATION, CONTROL AND ELECTRICAL SYSTEMS INFORMATION A.
The following information pertaining to the instrumentation, control and electrical systems of TMI-2 is needed at headquarters so we can effectively support the ongoing activities at the site:
1.
Electrical Elementary or Schematic Control Circuit Diagrams (orDrawings). Based on information requests received at headquarters to date diagrams are needed in the following areas at this time:
a) Safety and non-safety related components capable of being supplied from the 4160 V and 480 V emergency buses.
b) Diesel generators and associated 4160 V supply breaker.
c) All the in-feeder and bus-tie breakers in the 4160 V and 480 V emergency buses.
d) All the safety and non-safety related components capable of being supplied from 125/250 V d-c buses, e) Reactor coolant pump breakers. Also, supporting electrical diagrams depicting the pump start permissives and trip signals and auxiliary equipment associated with the reactor i
coolant pumps (e.g., Reactor Pump Cooling System),
f) Condensate pumps, valves and supporting auxiliaries.
g) Condensate booster pumps, valves and supporting auxiliaries h) Circulating water system, pumps, valves and supporting auxiliaries.
- 1) Secondary services river water system pumps, valves and supporting auxiliaries.
j) Condenser vacuum pumps and supporting auxiliaries, k) Feedwater inlet valves to steam generators.
