Salem 2 Page 3 of 47 Rev. 40 3.0 PRECAUTIONS AND LIMITATIONS
___ 3.1 This procedure does not duplicate or override any precautions and limitations referenced in approved operating procedures during the cooldown process. Steps are provided in this procedure to ensure conditions are satisfied prior to Mode changes IAW Administrative and Technical Specifications requirements.
___ 3.2 At least one Source Range Channel, OHA E-13, SR HI FLUX AT S/D, and the Audio Count Rate Channel should be OPERABLE anytime the reactor is shutdown.
___ 3.3 23 Charging Pump flow path shall be aligned to Unit 1 OR the pump shall be C/T when 21 or 22 Safety Injection Pump is capable of injection into the core with RCS temperature #312°F with the Reactor Vessel Head installed.
[C0565]
___ 3.4 1CV462, CHARGING CROSS TIE MOV may spuriously open due to a hot short in its power cable or control circuit during a fire on Unit 1. The design basis for Unit 2 POPS may be challenged with the additional charging flow from Unit 1.
For this reason, 1CV464, CHARGING CROSS TIE ISOLATION VALVE is to be CLOSED when Unit 2 RCS temperature is #312°F.
___ 3.5 RCS dilutions are allowed IAW S2.OP-SO.CVC-0006(Q), Boron Concentration Control, provided:
RCS is maintained above the Cold Shutdown Boron Concentration IAW S2.RE-RA.ZZ-0016(Q), Curve Book.

S2.OP-IO.ZZ-0006(Q)
Salem 2 Page 4 of 47 Rev. 40
___ 3.6 The following requirements are applicable to heatup or cooldown and plotted IAW S2.OP-TM.ZZ-0001(Q), RCS Pressure/Temperature Curves:
3.6.1 Pressurizer Insurge/Outsurge (WCAP 14950):
During normal RCS heatup and cooldown evolutions, some plant operating practices induce pressurizer insurge and outsurge cycles. These cycles can introduce additional fatigue loading to the lower end of the pressurizer when the temperature difference between the RCS and PZR is significant.
Existing plant instrumentation cannot be relied upon to detect the occurrence of this condition.
During Pressurizer cooldown evolutions, the Pressurizer Surge Line temperature should be monitored to ensure an outsurge and relatively stable temperature is maintained.
Pressurizer Surge Line temperature should trend with the saturation temperature in the Pressurizer. Pressurizer Surge Line temperature trending away from the saturation temperature and towards RCS Hot Leg temperature is an indication of an insurge.
To minimize Pressurizer insurge during RCS cooldown, Charging flow should be adjusted to offset the change in RCS volume while maintaining Pressurizer Level relatively constant. Another strategy would be to maximize Pressurizer Spray flow while maintaining Pressurizer Level relatively constant.
The pre-job brief should discuss factors that may have a significant impact on pressurizer insurge and outsurge cycles. Factors such as, Pressurizer Heater capacity, RCS heatup / cooldown rates and Charging / Letdown flow adjustments can all contribute to undesirable pressurizer insurge and outsurge cycles. The use of human performance reduction tools should also be discussed.
When a Pressurizer insurge that causes a >100°F step change in PZR surge line temperature is identified:
C Efforts should be made to allow the water to reach equilibrium temperature prior to initiating an outsurge.
C A Notification directed to Engineering is to be initiated for evaluation IAW WCAP 14950.
S2.OP-IO.ZZ-0006(Q)
Salem 2 Page 5 of 47 Rev. 40 3.6.2 T/S Surveillance 4.4.10.1.1: The Reactor Coolant System pressure and temperature (except the pressurizer) shall be determined to be within the limits at least once per 30 minutes during system heatup, cooldown, and inservice leak and hydrostatic testing operations with:
A maximum heatup of 100°F in any one hour period.
A maximum cooldown of 100°F in any one hour period.
A maximum cooldown of 50°F in any one hour period when RCS temperature is <200°F.
A maximum temperature change of #5°F in any one hour period during hydrostatic testing operations.
3.6.3 T/S Surveillance 4.4.10.2: The pressurizer temperatures shall be determined to be within the limits at least once per 30 minutes during system heatup or cooldown.
The spray water temperature differential shall be determined to be within the limit at least once per 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br /> during auxiliary spray operation with:
A maximum heatup of 100°F in any one hour period.
A maximum cooldown of 200°F in any one hour period.
A maximum spray water temperature differential of 320°F.
3.6.4 Cooldown step changes should be limited to <25°F/hour. A step change is considered a large temperature change within a few minutes followed by essentially constant temperature for the balance of the hour. This is considered good operating practice (DES-DEF-90-01584).
3.6.5 RCS shrinkage will occur during RCS cooldown. Sufficient pressurizer inventory should be established prior to initiating RCS cooldown activities. At least 13,000 gallons of makeup water will be needed to cooldown from 547°F to 350°F and an additional 7,300 gallons will be needed to cooldown to 200°F.
Additionally, the 45 gpm letdown orifice and RCS makeup source from the RWST may be used to maintain a relatively constant pressurizer level.
3.6.6 During a Cooldown/Depressurization, Letdown flow will decrease as RCS Pressure drops. 23 Charging Pump linkage adjustment OR 2CV55 Low Flow control should be made ready prior to reaching this condition to preclude a rapidly increasing pressurizer level.
3.6.7 As RCS cooldown progresses, the maximum cooldown rate provided by the Steam Dump System drops significantly as RCS temperature approaches 400°F.
3.6.8 The cooldown rate provided by the Steam Dump System is affected by changes in Condenser backpressure. For example, starting a vacuum pump increases the steam flow through the system and increases the RCS cooldown rate.

___ 3.7 The automatic isolation time of <5 seconds for MSIVs pertains to the OPERABILITY of the MSIVs in Modes 1-3 per the requirements of T/S 3.7.1.5. S/R 4.7.1.5 states that each MSIV is demonstrated OPERABLE in Modes 1-3 by verifying full closure within 5 seconds when tested pursuant to T/S 4.0.5. Thus, the closure time pertains to main steam line isolation, not containment isolation.
T/S 3.6.3 pertains to OPERABILITY of the containment isolation valves in Modes 1-4.
The main steam isolation valves (MSIVs) fulfill their containment isolation function as remote-manual containment isolation valves. The automatic closure of the MSIVs is NOT required for containment isolation due to having a closed system inside containment.
[80045103]
___ 3.8 When a MSIV is being relied upon as a remote-manual valve and either of the following conditions exist, the MSIV is inoperable IAW T/S 3.6.3:
With secondary side steam pressure <118 psia (Tavg <340°F)
AND the hydraulic actuator is NOT capable of closing the valve, or
With secondary steam side pressure $118 psia (Tavg $340°F) and S2.OP-ST.MS-0003(Q) has NOT been performed within the last 92 days, AND the hydraulic actuator is NOT capable of closing the valve.
If either of the above conditions exist, the Mechanical Shaft Locking Device(s) is to be installed to secure the MSIV(s) in the closed position to comply with T/S 3.6.3.b.
___ 3.9 When a MSIV is being relied upon as a remote-manual valve and the valve hydraulic actuator is NOT capable of closing the valve, the MSIV is inoperable IAW T/S 3.6.3.
___ 3.10 The Post-Fire Safe Shutdown Equipment Administrative Controls, action level requirements are to be implemented should the MSIVs be closed in Step 5.1.35 or 5.1.36, IAW OP-SA-108-115-1001, Operability Assessment And Equipment Control Program
[80067063].
___ 3.11 The preferred method for RCS cooldown is by using the
[CAPR 70010788]
Steam Dump System in the Main Steam Pressure Control Mode. Operations Manager approval is required to utilize the MS10, Atmospheric Steam Relief Valves for normal cooldown OR normal RCS temperature control. This requirement does NOT supersede the authority of a licensed operator to use the MS10 valves to control RCS temperature in abnormal situations where the preferred heat sink is NOT available or inadequate.
___ 3.12 RCS cooldown via 21-24MS10 requires close monitoring of steam pressures to preclude inadvertent SI from Steam Generator differential pressure.
S2.OP-IO.ZZ-0006(Q)
Salem 2 Page 7 of 47 Rev. 40
___ 3.13 Chemistry is to be notified whenever steam is released from the Steam Generators to the atmosphere by way of any MS10, S/G Safety valve, or steam driven AFP exhaust.
Chemistry will need to know the duration of the steam release as well as the affected Steam Generator(s). With this information, Chemistry can calculate the radioactive material concentration in the steam relative to that in the steam generator water IAW the ODCM section for Secondary Side Radioactive Gaseous Effluents and Dose Calculation. [70028596]
___ 3.14 The ability to reduce Reactor Coolant System or Steam Generator metal temperature is hindered when RCS water inventory is reduced. As a result of this, upcoming outage activities, such as the removal of S/G primary manway covers, should be reviewed prior to reducing RCS water inventory.
[70034006]
___ 3.15 In Modes 1-3, 2/3 S/G Level Channels at #14% on any Steam Generator is considered an ESF Actuation regardless of AFW Pump status [70027485]. For this reason, 21-24 S/G narrow range levels are to be maintained $28% during the RCS cooldown.
The RCS cooldown rate is to be reduced when any S/G is <28% narrow range level.
The RCS cooldown is to be suspended when any S/G is #24% narrow range level.
RCS cooldown may recommence when all S/G narrow range levels are >28%.
[70067944]
___ 3.16 Cold Shutdown Testing (CST) requirements as described in ER-AA-321, Administrative Requirements for Inservice Testing [70039673]:
All due and overdue Cold Shutdown Testing procedures are required to be performed during a Refueling Outage prior to returning the plant to operation.
Cold Shutdown Testing is also required when the plant is placed in Mode 5 from Mode 4 (Mode 5 being the trigger) for reasons other than Refueling Outage. It is NOT the intent of the Inservice Testing Program to hold the plant in cold shutdown in order to complete Cold Shutdown Testing, however, it is the intent to complete as many tests as possible on a good-faith basis.
The Station Planning Operations scheduler will schedule testing based on a Cold Shutdown, Refueling and Extended Outage testing list provided by the IST Program Engineer. Scheduled testing is to be started no later than 48 hours5.555556e-4 days <br />0.0133 hours <br />7.936508e-5 weeks <br />1.8264e-5 months <br /> after reaching Mode 5 and is to continue until the plant is ready for Mode 4 entry at which time any in-progress 4.0.5V surveillances are completed without initiating others. In some cases Cold Shutdown Testing may be required to be performed in Mode 4 or Mode 3 depending on the overdue dates relative to testing already performed during Mode 5.

___ 3.17 S2.OP-AB.RHR-0001(Q), Loss Of RHR, is to be reviewed prior to opening any RCS Vent Path within 6 hours6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br /> of reactor shutdown with the Containment Equipment Hatch open.
___ 3.18 When the RCS is vented to the Containment with either the Containment Equipment Hatch or a Containment Air Lock OPEN, the vent path established must be capable of being closed prior to the time to Core Boiling as determined by S2.OP-AB.RHR-0001(Q).
When the RCS is vented to the Containment, Salem's interpretation of NUMARC 91-06 requires that either the RCS is made intact prior to the time to core boiling should RHR be lost (applicable when the RCS loops are filled and two or more Steam Generators are available as a heat sink for Natural Circulation. Heat sink means the Steam Generators has a feed make-up source available, Secondary water level above the U-tubes, and a Steam Generator vent path), OR Containment Closure is established prior to time to core boiling should a Loss of RHR occur. (Containment Closure in this statement only applies to the Containment Equipment Hatch and the Containment Air Locks; Containment Closure of all other penetrations is required prior to Core Uncovery and is established IAW S2.OP-AB.CONT-0001(Q) [80082938].
___ 3.19 An alternate Pressurizer Cold Scaled Level indication for at least one
[CAPR 70090887]
of the three hot calibrated PZR Level Channels is to be provided whenever the PZR Liquid/Vapor temperature is #210°F. A Cold Scaled Level indication is simply a hot calibrated channel with a different meter scale. The scaling was developed utilizing the known relationship between the hot and cold calibrated channels at 140°F as depicted in Exhibit 1. It should be noted that the Indicated Pressurizer Level (%) displayed in Exhibit 1 graphs were developed using existing Hot Calibrated channel scaling and cannot be used with selected Cold Scaled Level indication(s). Cold Scaled Level indication(s) may be provided at anytime after Mode 4 is entered, however at least one indication is to be provided prior to lowering pressurizer level at Step 5.1.59.
4.0 EQUIPMENT/MATERIAL REQUIRED 3/64 Hex Key (Allen) wrench (for Maintenance to provide Cold Scale Level indications)

Salem 2 Page 32 of 47 Rev. 40 CAUTION [CAPR 70090887]
Refer to Exhibit 1, Pressurizer Level Channels, for channel behavior based on pressurizer water temperature.
The expected PZR COLD CAL level value in SPDS (U2LT0462S)
[70090500]
in a water solid condition is <105%. An indicated level of $105% is highly suspect.
Maintenance is to be notified to troubleshoot the apparent failure of the instrument whenever the indicated value is not as expected.
When
.528 gallons has been drained from the RCS, the PZR COLD CAL level should indicate.95% (PZR at.200°F) (Actual level at 100%).
When
.2500 gallons has been drained from the RCS, the PZR COLD CAL level should indicate.82% (PZR at.200°F) (Actual level at.84%).
At
.60% COLD CAL level, PZR Level Channels I, II, & III should begin to come on scale at.98.8% (.61.0% on COLD SCALED LEVEL indication).
At
.20% PZR Level Channels I, II, & III should approximate the COLD CAL Level, (crossover). PZR Level Channels I, II, & III are normally off scale low at
.11.5% COLD CAL level.
The PZR volume from a water solid condition to 25% level is.9,978 gallons.
There is.12,600 gallons between the upper and lower level taps and.528 gallons from the upper level tap to a water solid condition.
