- O ma RESIDUAL HEAT REMOVAL SYSTEM 1.0 PURPOSE 4
This procedure provides the necessary instructions for operation of the Residual Heat Removal System (RHRS).
This procedure also provides instructions for filling the Reactor Coolant System (RCS) and/or the Refueling Cavity and for draining the Refueling Cavity using the RHRS.
Instructions are included in the following steps:
4.1 Placing A Train Of RHR In Standby Readiness 4.2 Placing The RHRS*In Service For RCS Cooldown 4.3 Establishing RHR Letdown 4.4 Shifting RHR Trains 4.5 Two Train RHR Operation During RCS Recirculation J
4.6 Filling And Venting The RHRS 4.7 Filling The RCS (And The Refueling Cavity For Refueling) 6.8 Onining The Refueling Cavity 4.9 Operating RHR With One Train Of Cold Leg Discharge With Its Cold Leg Flowpath Isolated For Maintenance 2.0 PRECAUTIONS AND LIMITATIONS 2.1 PRECAUTIONS 2.1.1 7a
. vent overheating the Component Cooling Water Syt (CCWS), cooling water flow to the RHR Heat E m uger should not be throttled.
2.1.2 To avoid thermal shock of the RCS components, the flow through the RHRS should be initiated and reduced O
slowly.
V 2.1.3 The RCS pressure and temperature should not exceed 425 psig and 350*F when the RHRS is in service, 9202190428 920116 m,c,,

2.1.4 Thoroughly fill and vent all applicable RHR components prior to returning them to service after maintenance.
l This minimizes system performance degradation and water hammer due to gas entrainment.
2.1.5 Only one RHR train should be altered at a time when changing system configuration.
This helps maintcin RHRS operability.
2.1.6 Whenever the RCS is at 188 feet (one foot above mid-nozzle) the RHRS flow should be limited to the lower end of a range from 3000 to 3500 gpm.
This minimizes potential loss of RHR Pump suction due to gas entrainment from vortex formation.
2.1.7 Valves 1-HV-8716A and 1-HV-8716B have a vent hole drilled on the RHR Pump side of the disc.
The valves are not capable of a leak tight seal when pressurized from the opposite Train RHR Pump.
2.1.8 When cooling down the RCS using one Train of RHR, the Recycle Evaporator should be shut down or supplied from the Unit 2 ACCW System.
This minimizes the heat loads on the NSCW System.
f)
2.2 LIMITATIONS J
2.2.1 With the RCS Tavg greater than or equal to 350*F, the RHRS is required to be operable per Technical Specification 3.5.2.
2.2.2 With the RCS in Hot Shutdown, the RHRS is required to be operable or in operation per Technical Specification 3.4.1.3.
2.2.3 With the RCS Tavg less than 350'F, the RHRS is required to be operable per Technical Specification 3.5.3.
2.2.4 With RCS in Cold Shutdown, the RHRS is required to be operable or in operation per Technical Specification 3.4.1.4.1 and 3.4.1.4.2.
2.2.5 During refueling operations, the RHRS is required to be operable and in operation per Tcc.hnical Specification 3.9.8.1 and 3.9.8.2.
2,2.6 If required for Cold Overpressure Protection, two RHR Suction Relief Valves are required operable per Technical Specification 3.4.9.3.
2.2.7 When in Mode 1, 2, or 3 1-HV-8809A/B and 2-HV-8816A/B (3) must remain open.
However, one valve at a time may be closed for surveillance testing.

CAUTIONS a,
,If vent 1-HV-10465-is not closed when venting is complete, venting RHR Train A will result in overflowing contaminated water from the Vent Valve Room down into the Auxiliary Building vestibule R-C131 (Level C).
b.
If vent 1-HV-10466 is not closed when venting is complete, venting RER Train-B will result in contaminated water on the floor of the room containing the Train B vent, and actuation of the
. room sump-level switch light on Panel QPCP.
NOTE RHR-Suction Vent Valves 1-HV-10465 (10466) are in sealed rooms and therefore cannot be O
visually observed as vented.
Personnel at these locations should stand outside the knockout wall-and verify adequate venting by listening for a change in the sound indicating that the air is vented.
4.6.10 Prior to opening lRRR Suction Vent Valves.1-HV-10465' (10466), NOTIFY Health Physics Department to monitor Room R-Cl31 (R-B08) in Auxiliary Building to contain spillage and minimize room contamination.

CAUTIONS a.
Maintain seal injection flow whenever RCS level is at or above the level of the a RCP Seals (elevation 190 feet).
This prevents crud infiltration into the seal chambers, b.
Airborne activity should be monitored when filling the Refueling Cavity from RHR until the level is above the Reactor Vessel Flange.

'O operable with one train in operation.
b.
Performance of this step assumes use of the RHR train that is operable but not operating.
