PLANT SYSTEMS BASES i
The UPS HVAC System ensures that the UPS & Distribution Rooms ambient air temperatures l
do not exceed the allowable teniperatures per Specification 3/4.7.10 for continuous-duty rating for the equipment and instrumentation cooled by this equipment.
The UPS HVAC System consists of a) a dedicated 100% apacity UPS Room Fan Coil Unit
{
(FCU) in each safety related UPS & Distribution Room and b) two, each 100% capacity, electrically independent and redundant UPS NC Trains either of which can provide redundant
?'
and diverse backup cooling for all four UPS & Distribution Rooms.
Either a UPS & Distribution Rooms' UPS Room Fan Coil Unit or an UPS NC Train are capable of maintaining the UPS & Distribution Room below its design temperature limits during normal
- and accident conditions.
The UPS HVAC system is a normally operating system. Each FCU normally provides the required temperature control to maintain its respective room below 104'F during normal plant
{
conditions. A single A/C train can also provide the required temperature control to maintain the UPS & Distribution rooms between below 104*F during normal plant conditions.
F j
The UPS Room FCUs are dedicated to the UPS Unit and Train they support. The UPS A/C 1
Train components are arranged in redundant safety related trains. During emergency
}
operation, the UPS HVAC System maintains the temperature below 104'F. Starting with minimum OPERABLE equipment required by the LCO, a single active failure of a component of 3
the UPS HVAC System, with a loss of offsite power, does not impair the ability of the system to perform its design function.
The UPS HVAC system is OPERABLE when each UPS & Distribution Room is supported by either an OPERABLE UPS Room FCU or an OPERABLE UPS A/C Train which is the same electrical train as the. UPS in that room.
A FCU is considered OPERABLE as long as it is in the "on" position and it has cooling water and its fan is operating. If a FCU is "off" for maintenance or other reasons it is not considered OPERABLE since it will not start automatically. A FCU in the "ON" position restarts when power is regained following a loss of offsite power. A UPS A/C train starts'on a acuation signal and therefore is OPERABLE, if in standby.
l In the event a FCU is inoperable and the respective A/C Train is also inoperable,100% cooling can be provided by the opposite train's NC Train. If one or more UPS & Distribution Rooms does not have "same Train" cooling, a single failure in the opposite Train could result in a loss COMANCHE PEAK - UNITS 1 AND 2 B 3/4 7-8 Unit 1 - Amendment No. 8;44, 61 Unit 2 - Amendment No. 47 1..-

BASES of cooling *.o the afketed rooms and loss of the fur.ction of the equipment in the UPS &
Distributio!) Room of the opposite Train. As a result, the temperatures in the affected room would inemase until it exceeded the maximum demonstrated operating temperature for the equlpmeniin the room. 30 days is an acceptable completion time to restore "same Train" cooling due to the flexibility in the design with room coolers for each room and redundant UPS AiC ' cains which are each capable of cooling all the UPS & Distribution Rooms.
it one or more UPS & Distribution Rooms looses all cooling, the affected rooms will begin to heat up. If either or both UPS NC Trains is circulating air through the supported areas, the mixing will result in a much slower rate of temperature increases. The completion time of 72 hours8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br /> allows restoration before the temperature rises to a level that the equipment in the i
affected rooms are impacted. To confirm the equipment's OPERABILITY, the temperature in the affected rooms is verified to be less than or equal to 104'F within one ho'ur and every 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br /> thereafter.
1 If one or more UPS & Distribution Rooms looses forced cooling and neither UPS A/C Train is c;rculating air in those rooms or if both rooms Icose forced cooling, the temperature rise is expected to affect equipment operability in a short period of time. One hour is allowed to restore circulating air or forced cooling.
Each acutation signal should be tested during the test frequency. The applicable signals for the UPS A/C Trains are the Safety injection Signal (SIS) and Stati>n Blackout Signal (BOS).
3/4.7.12 SAFETY CHILLED WATER SYSTEM The OPERABILITY of the Safety Chilled Water System ensures that sufficient cooling capacity is available for continued operation of safety related equipment during normal and accident conditions. The redundant cooling capacity of this system, assumi, a sing lc failure,is consistent with the astumptions used in the safety analyses.
3/4.7.13 MAIN FEEDWATER ISOLATION VALVE PRESSURE / TEMPERATURE LIMIT The fracture toughness requirements are satisfied with a metal temperature of 90*F for the main feedwater isolation valve body and neck, therefore, these portions will be maintained at or above this temperature prior to pressurization of these valves above 675 psig. Minimum temperature limitations are imposed on the valve body and neck of main feedwater isolation valves HV-2134, HV-2135, HV-2136 and HV-2137. These valves do not need to be verified at or above 90'F when in MODES 4, 5, or 6 (except during special pressure testing) since To
< 350'F which corresponds to a pressure at the valves of 140-150 psig or less. The maximum pressurization during cold conditions (valve temperature < 90'F) should be limited to no more than 20% of the valve hydrostatic test pressure (3375 psig x 20% = 675 psig).
