Hope Creek Page 4 of 77 Rev. 25 3.0 PRECAUTIONS AND LIMITATIONS
3.1 Precautions
3.1.1. BC-HV-F024A(B) RHR LOOP TEST RET MOV will drain the Reactor Vessel to the Suppression Pool if opened in Shutdown Cooling.
[CD-389B, CD-608D, CD-567E] ____ 3.1.2. BC-HV-F027A(B) RHR LOOP A(B) SUPP POOL SPRAY HDR ISLN MOV will drain the Reactor Vessel to the Suppression Pool if opened while the associated RHR Pump is in Shutdown
Cooling. To prevent this from occurring, the BC-HV-F027A(B) is CLOSED and tagged while in Shutdown Cooling. ____ 3.1.3. BC-HV-F007A(B) RHR PUMP A(B) MIN FLOW MOV will drain the Reactor Vessel to the Suppression Pool if opened in
Shutdown Cooling, due to flow below the low-flow setpoint
precluding automatic valve closur
- e. To prevent this from occurring, the BC-HV-F007A(B) is CLOSED and tagged while in Shutdown Cooling.
[CD-389B, CD-608D, CD-567E] ____ 3.1.4. Opening BC-HV-F009 S HUTDOWN COOLING INBD ISLN MOV may cause a decrease in Reactor water level.
[CD-608D, CD-567E] ____ 3.1.5. IF Shutdown Cooling CAN NOT be placed in service and Reactor Recirc Pumps are NOT available, then the Reactor vessel level should be raised slowly to 80 inches, Reactor level shutdown range, using temperat ure compensated indication, (Vessel Level Instrumentati on Temperature Compensation Curves may be required), to allow for natural circulation. Vessel
metal temperatures above and below the water level, and
Reactor Coolant System Temper ature/Pressure Data should be monitored to ensure the T/S Cool Down limits are NOT exceeded. Also, the Reactor Water Cleanup system should be utilized in maximum cooling.
[CD-693A, CD-178A, CD-973B] ____ 3.1.6. Discharge of water > 200°F to Liquid Radwaste System should NOT be allowed. ____ 3.1.7. DEFEATING the NSSSS Isolation Signals (including the loss of RPS power to NSSSS Isolation logic), to BC-HV-F008, BC-HV-F009, BC-HV-F015A AND BC-HV-F015B (Shutdown
Cooling Valves), shall only be performed using
HC.OP-GP.SM-0001(Q), Defeating NSSSS Isolation Signals For Shutdown Cooling.
[CD-847E] ____
HC.OP-SO.BC-0002(Q)
Hope Creek Page 5 of 77 Rev. 25 3.1.8. During plant Cooldown/Depre ssurization, similar Reactor water level instrumentation should be monitored for significant deviation (indicating possible reference line De-gassing)
AND all maintenance activities which have the potential of draining the Reactor Vessel should be terminated. ____ 3.1.9. During Shutdown Cooling Oper ations, isolation of SACS Cooling Water to the RHR Heat Exchanger could result in saturated
conditions and subsequent water hammer transients when resuming cooling water flow.
[CD-562G] ____ 3.1.10. The RHR System discharge m anual cross-tie lines should NOT be used for normal Shutdown Cooling, Suppression Pool Cooling, or Suppression Pool Spray. The lines should only be
used as an alternate decay heat removal (ADHR) path IAW HC.OP-AB.RPV-0009(Q), Shutdown Cooling.
[CD-609G] ____ 3.1.11. Since the RHR System crosst ie piping/valves were not tested with respect to the effects of thermal expansion on supports, restraints, and snubbers beyond 300 °F, crosstie flushing is
prohibited when the flushing medium temperature is greater than 300 °F, or 67 psia (52.3 psig).
[70039531, UFSAR 3.9.2.2.2] ____ 3.1.12. The sampling requirements of UFSAR Section 5.2.3.2.2.2 should be met whenever the Reactor Coolant Chemistry sampling flowpaths have been isolated, and any alternate sampling method used should be temperature compensated. ____
3.1.13. IF any instrument affected by this section appears to be indicating erroneously, THEN NOTIFY I&C to fill and vent the associated transmitter(s). ____
HC.OP-SO.BC-0002(Q)
Hope Creek Page 6 of 77 Rev. 25 3.2 Limitations
3.2.1. Independent
Verification may be performed following completion of the procedure activity or upon completion of each step. If performance of an "
ENSURE" step which has an IV signoff results in NO component manipulation then the IV signoff should be N/A'd upon completion of the step. ____ 3.2.2. If valve or electrical li neup CANNOT be completed as required, then, the SM/CRS will determine whether the deviations are
such that the system should NOT be placed in service or standby, as required. ____ 3.2.3. The Reactor Coolant System cooldown limitations of T/S 3/4.4.6 shall be observed. ____ 3.2.4. While the RHR System is operating in the Shutdown Cooling mode, any valve manipulations which would prevent ANY of the rated shutdown cooling flow ( 10,000 gpm) from returning to the reactor vessel via the respective Recirculation System discharge
piping and jet pumps should NOT be performed. For example, recirc suction and discharge valves being open simultaneously in
the loop seeing Shutdown Cooling return flow would result in a
portion of the return flow being diverted back through the
recirculation loop in the reverse direction, as opposed to into the
respective jet pumps, where forced circulation through the core
would occur. This limitation does NOT preclude reducing
shutdown cooling flow to satisfy Limitations 3.2.21, 3.2.22 or
3.2.24 provided the Cavity is flooded, reducing reactor cavity
level using Steps 5.2.38 or 5.2.39, or when intentionally reducing Shutdown Cooling flow to support Noble Metals Chemical Application.
[CD-122H] ____ 3.2.5. While the RHR System is operating in the shutdown cooling mode, maintaining the rated shutdown cooling flow of approximately 10,000 GPM to the Reactor vessel via the
respective Recirculation System discharge piping and Jet Pumps
is essential to assure that the RHR Heat Exchanger inlet
temperature is representative of actual bulk coolant temperature.
[CD-122H] ____ 3.2.6. During the transition from Shutdown Cooling operations to establishment of normal Reactor Recirculation System operations, the RHR System may be left in Shutdown Cooling, ONLY if BP202 is the RHR Pump in service AND AP201 is the Reactor Recirculation Pump to be started. ____
HC.OP-SO.BC-0002(Q)
Hope Creek Page 7 of 77 Rev. 25 3.2.7. IF while the RHR System is operat ing in the shutdown cooling mode, a degraded shutdown cooling condition occurs, or IF there is indication that the RHR Heat Exchanger inlet temperature may NOT be representative of average reactor coolant temperature, then HC.OP-AB. RPV-0009(Q), Shutdown Cooling., should be referred to. ____ 3.2.8. The time when NEITHER the RHR System (operating in the Shutdown Cooling Mode) OR the Reactor Recirculation System is in operation should be minimized. ____ 3.2.9. During the transition from no rmal Reactor Recirculation System operations to establishment of Shutdown Cooling, only the AP201 Reactor Recirculation Pump may be left in operation until
the BP202 RHR pump is operating satisfactorily, and then only until the required B RHR Loop flow of 10,000 gpm is achieved.
This limitation does NOT apply when Noble Metals Chemical Application is to be performed during plant shutdown. ____ 3.2.10. The Discharge Valve of any Reactor Recirculation Pump which is NOT in operation must be closed prior to establishing forced
circulation using the RHR System in the Shutdown Cooling Mode of operation. Opening an idle reactor recirculation pump
Discharge valve during Shutdown Cooling operations may be
performed provided that the asso ciated reactor recirculation pump Suction valve is closed.
[CD-739A, CD-781A] ____ 3.2.11. B RHR is preferred to be us ed for Shutdown Cooling operation due to its Liquid Radwaste System connection. B RHR when
combined with A Reactor Recirc Loop provides continuous
forced circulation during the transition to Shutdown Cooling
operations. B RHR or A RHR should only be placed in service
once the differential temperat ure between the Reactor Vessel water and the water in the RHR Loop to be placed in service is less than 100°F. ____ 3.2.12. The RHR loop used for shutdown cooling should be associated with the SACS loop that is NOT supplying TACS. ____
HC.OP-SO.BC-0002(Q)
Hope Creek Page 8 of 77 Rev. 25 3.2.13. The following parameters shoul d be used if there is uncertainty as to whether the plant has ent ered Operational Condition 3 or as additional indications for monitoring purposes. IF the following indications are indicati ve of an Operational Condition change then, the appropriate r eports should be initiated:
[CD-122H] ____ An increase in Reactor Head Vent temperature could be indicative of the onset or verify the presence of boiling in the vessel. This temperature is monitored by TE-N064 (when
BB-HV-F001 and BB-HV-F002 are open), and can be read
on the Control Room recorder B21-TRR614 - point 24, Reactor Head Vent. ____ An unexplained increase in Drywell leakage could be indicative of the presence of steam flow out of the vessel head and into the Drywell. This parameter is monitored at RMS and includes primarily t he Drywell Equipment Drain flow. However, steaming into the Equipment Drain Sump
could also be indicated by total Drywell leakage and Drywell
Cooler condensate flow. Therefor e, all of these points should be monitored for unexplained increases. ____ (continued on next page)
HC.OP-SO.BC-0002(Q)
Hope Creek Page 9 of 77 Rev. 25 3.2.13 (continued)
An increase in steam dome pressure could be indicative that boiling, to some degree, is occurring in the reactor core. This
parameter should be monitored using the redundant Reactor pressure indications given in Table 3.2.13, particularly those
with the lowest ranges such as Reactor Low Range Pressure or the HPCI and RCIC trip units. ____
