3/4.7.6 FLOOD PROTECTION l
LIMITING CONDITION FOR OPERATION 1
3.7.6 Flood protection shall be provided for the service water pump cubicles and components when the water level exceeds 13 feet Mean Sea Level, tJSGS datum, at the Unit 3 intake structure.
l APPLICABILITY: At all times.
AGJ1DH:
With the water level at greater than 13 feet above Mean Sea Level, USGS datum, l
at the Unit 3 intake structure, shut the watertight doors of both service water pump cubicles and close the pump cubicle sump drain valves within 15 minutes.

MILLSTONE - UNIT 3 3/4 7-14 Amendment No.144 M14
BASES l
SURVEILLANCE REQUIREMENTS For'the surveillance requirements, the UHS temperature is measured at the locations described in the LC0 write-up provided in this section.
Surveillance Requirement 4.7.5.a verifies that the UHS is capable of providing a 30-day cooling water supply to safety-related equipment without exceeding its design basis temperature. The 24-hour frequency is based on operating experience related to trending of the parameter variations durira the applicable modes. This surveillance requirement verifies that the average water temperature of the UHS is less than or equal to 75'F.
l Surveillance Requirement 4.7.5.b requires that the UHS temperature be i
monitored on an increased frequency whenever the UHS temperature is greater l
than 70*F during the applicable modes. The intent of this Surveillance Requirement is to increase the awareness of plant personnel regarding UHS.
temperature trends above 70*F.
The frequency is based on operating experience related to trending of the parameter variations during the applicable modes.
l 3/4.7.6 FLOOD PROTECTION The limitation on flood protection ensures that the service water pump cubicle watertight doors will be closed and the pump cubicle sump drain valves will be closed before the water level reaches the critical elevation of 14.5 feet Mean Sea Level.
Elevation 14.5 feet MSL is the floor elevation of the service water pump cubicle.
3/4.7.7 CONTROL ROOM EMERGENCY VENTILATION SYSTEM' BACKGROUND The control room emergency ventilation system provides a. protected environment from which operators can control the unit following an uncontrolled release of radioactivity. Additionally, the system provides temperature control for the control room during normal and post-accident operations.
The control room emergency ventilation system is comprised of the control room t
emergency air filtration system and a temperature control rystem.'
The control room emergency air filtration system consists of two redundant systems that recirculate and filter the control room air.
Each control room emergency air filtration system consists of a moisture separator, electric heater, prefilter, upstream high efficiency particulate air (HEPA) filter, charcoal adsorber, downstream HEPA filter, and fan. Additionally, ductwork, valves or dampers, and instrumentation form part of the system.
Normal Doeration A portion of the control room emergency ventilation system is required to operate during normal operations to ensure the temperature of the control room is maintained at or below 95'F.
