Rod thermal lock-up is NOT a concern when the reactor trip breakers are OPEN. If reactor trip breakers are CLOSED and an RCS cooldown of greater than 50°F is planned, the shutdown and control banks should be withdrawn at least 5 steps each. This will limit the possibility of thermal lock up of the rods. This does not apply if performing sections 8.5 or 8.6.
B. If both MG sets are to be shutdown, the control rods and shutdown rods shall be inserted in the core and the reactor trip breakers OPEN prior to shutting down the MG sets.
C. Reactor Trip Breakers shall NOT be closed while in Mode 3 unless in compliance with LCO 3.4.1.2.
D. Failure to perform 1,2-Pl-IFT-099-0P4.0, Verification of P4 Contacts could result in the prevention of AUTO SI if required.
E. Under normal conditions, the control rod banks must be withdrawn and inserted in the prescribed sequence. For withdrawal the sequence is Shutdown Bank A, Shutdown Bank B, Shutdown Bank C, Shutdown Bank D, Control Bank A, Control Bank B, Control Bank C, and Control Bank D. The insertion sequence is the reverse of the withdrawal sequence.
F. For manual bank sequencing, the prescribed withdrawal and insertion sequence should be followed. Rod motion of the correct bank should be monitored by observing the group step counters and the rod position indicators.
G. During Control Rod withdrawal, the Control Banks should be monitored for bank overlap.
H. The control banks must be maintained above their respective insertion limits (Low-Low Alarm to ensure adequate shutdown in the event of a reactor trip, to ensure that maximum possible ejected rod reactivity limits are maintained and to ensure acceptable core power distributions.
I. Before withdrawing any rod bank from the fully inserted position, the group step counters and the rod position indicators for that bank must be at zero steps.

J. Deleted K. RPIs and step counters shall be maintained within limits per TS 3.1.3.1 and 3.1.3.2.
L. The Control Rods shall NOT be stepped or tripped unless the RCS pressure is at least 100 psig.
M. Rod movement without the CRDM fans aligned to the Reactor Vessel shroud is allowed, provided that the RCS temperatures are less than 350° F.
N. When RCS temperatures are greater than 350° F, continuous rod motion shall comply with these restrictions:
CRDM OUTLET                      ROD MOTION LIMITS TEMPERATURE 190°F          10 minutes ON          20 minutes OFF 200°F            6 minutes ON          24 minutes OFF Time limitations are due to a lower air flow rate of 48,000 cfm across the shroud combined with a higher temperature (Reference TSIR-97-BOP-30-636 and Westinghouse Letters RIMs #B38931005806, B38930920800, and B38931 005803).
N. The following failures will render the rod control system incapable of automatic and I or manual motion without any annunciation or indication:
: 1) Hand switch failure; 2) relay failure, and 3) failure of both lOOv DC power supplies (PS3 and PS6) simultaneously.
: 0. Defeating or restoring TavglDelta T or NIS channel may cause step change in input to rod control. A delay of at least 3 minutes prior to returning rod control to automatic will allow lead/lag signal to decay off.

Added step 5.1[1j to notify System Engineer that CLAs are about to be filled and VT-2 test may be required (PCR07001781). Added notes and steps to check nitrogen pressure locally in sections 8.3.1, 8.3.2, 8.3.3, and 8.3.4 (PCR08000053). Added caution to Appendix A, B, C, and D prior to step 7 about limiting MOV starts (PCRO8001 141).
Added P&L note M to require Void Volume Evaluation any time a segment of the ECCS system is drained (PCR08001174). Added note and step to all sections of 5.1, 5.2, and 5.3 about system operability and evaluation of void volume (PCRO8001 174). Added Caution Section 8.1 preceding steps [12}[dj[1}, [13][d]{1], [14j[d][1], and [15][d][1]
cautioning about CLA over-fill and over-pressurization (PCRO90001I2).Corrected steps referenced in Section 8.1 Note 1 from 13-thru-16 to 12-thru-15 (PCRO9000112).
 
SQN                    COLD LEG INJECTION                    1-50-63-1 i                        ACCUMULATORS                      Rev: 47 Page 6 of 185 3.0 PRECAUTIONS AND LIMITATIONS A. Venting large volumes of nitrogen from the cold leg accumulators could displace oxygen and create a hazardous atmosphere in the No. 4 Accumulator Room.
Prior to venting a significant volume of nitrogen from the cold leg accumulators, the No. 4 Accumulator Room shall be evacuated or continuous oxygen monitoring shall be established. If evacuated, a safe atmosphere should be verified prior to restoring access.
B. Cold Leg Accumulator (CLA) room temperatures must be maintained equal to or greater than 60&deg;F whenever the CLAs are pressurized (not open to atmosphere).
C. Tech Spec operability limit (including instrument uncertainty) for CLA borated water volume is between 7615 gallons and 7960, but Unit 1 CLA level indicators will indicate a maximum of 7956 gallons. Therefore, the CLA operability limit has been reduced to between 7615 gallons and 7955 gallons.
D. Tech Spec operability limit (including instrument uncertainty) for CLA nitrogen pressure is between 624 psig and 668 psig.
E. Do not change relief valve setpoints to allow more rapid pressurization. If Pressurization rate is inadequate, the SM should be contacted immediately for resolution.
F. Cross connection of the nitrogen or water supplies of any Cold Leg Accumulators will make the cross-tied accumulators inoperable. Do NOT cross-tie accumulators in Modes 1-3. [C.2]
G. Do not adjust pressure control valves 0-PCV-77-253 or 0-PCV-77-254.
Maintenance should be contacted for assistance if valves require adjustment.
H. To prevent premature bearing wear, SI pumps should be operated for a minimum of 20 minutes each time a pump is started.
I. To prevent brittle fracture when adding nitrogen to a CLA with accumulator pressure less than 600 psig, then the piping temperature between the nitrogen supply regulator (0-PCV-77-253 or -254) and the containment isolation valve (1-FCV-63-64) should be monitored and maintained greater than 40&deg;F. If temperature approaches 40&deg;F, nitrogen fill should be stopped or the flow rate reduced to maintain piping temperature greater than 40&deg;F.
J. Anytime accumulators are filled above 7956 gallons, the upper instrument level tap will need to be purged by Instrument Maintenance Group.
K. Limiting accumulator fill to 7916 gallons during the initial fill following an outage, prevents flooding of the upper instrument level leg. After calibration the lower instrument leg is unborated water and level instrument inaccuracies result.

L. In Modes 4, 5, and 6 (with vessel head on), CLA valves are required to be closed with motor breakers locked in OFF position unless CLA pressure is less than the maximum RCS pressure allowed by PTLR for current cold leg temperature. (LCO 3.4.12)
M. Engineering evaluation for air removal is required any time a segment of the ECCS system is drained. Ultrasonic testing may be required in order to validate air removal or to quantify any void volume that remains. This evaluation should consider whether or not the existing vent valves can completely remove all air pockets from the piping, and if not, the effect on the system of the remaining void in concert with other existing voids. During outages, the fill and vent can be verified by the subsequent performance of full flow testing. Evaluation of procedure sections can be performed in advance of actual use.

: 1. Section 5.5 3.0 PRECAUTIONS AND LIMITATIONS A. During normal operation, PRT water temperature should not exceed 120&deg;F.
B. Maintaining 3 to 6 psig N2 gas blanket on the PRT will prevent the formation of explosive hydrogen-oxygen mixtures.
C. The PRT concentration of oxygen shall be limited to less than or equal to 2% by volume whenever the hydrogen concentration exceeds 4% by volume.
D. Over filling the PRT to solid water condition during oxygen reduction per Section 8.8 may result in failure of the PRT rupture disc.
E. The PRT pressure should be maintained <7.5 psig during normal operation. (Except during the performance of section 8.9).
F. The PRT rupture discs are rated at 85 psig.
G. The level in the PRT should be maintained at 70%. If the level increases to 88%, then decreasing level to 70% is necessary. If the level decreases to 55%, then increasing level to 70% is needed when the PRT is required to be operable.
H. Completely draining the PRT may result in gas binding the RCDT pumps.
I. Water intrusion into the waste gas vent header is possible during PRT venting operations with PRT level high. This could affect RCP seal leakoff flows and the vent capability of tanks which vent to waste gas vent header.
J. PRT level indications or alarms are not available in the Aux Control Room, thus PRT level manipulations and feed & bleed processes are unavailable.

(09001296). This is an editorial change to clarify intent.
Modified Section 5.0 Acceptance Criteria A associated with a +/-2% delta between NIS and core thermal power to reflect the Tech Spec requirement. Any channel deviating from core thermal power by more than 2.0% is required to be adjusted. Removed special message boxes from Section 6.1 that incorrectly indicated specific parameters as Acceptance Criteria. Steps 6.1[5] and 6.1[8] were modified to present the allowable deviations between NIS and core thermal power within the step rather than as Acceptance Criteria. (PER 167130)
Relocated step associated with SRO notification of requirements for testing inoperable channels to later in Section 6.1 to provide a more logical sequence. This is an alteration to an administrative requirement and is a minor change.
Modified the tables associated with Steps 6.1[5j, 6.1[7j and 6.1[8] to clarify intent as a minor change.
A note was added prior to Step 6.1[10] to clarify pre-existing intent that bulleted steps are to be marked N/A as appropriate.
Added Precaution and Limitation H regarding the potential impact of Auxiliary Instrument Room temperature on core thermal power indication (09000640).

1.1      Purpose This Surveillance Instruction (SI) provides detailed steps for ensuring proper calibration of the power range neutron flux channels.
1.2      Scope 1.2.1    Surveillance Test to be Performed This Instruction performs a comparison between the power level calculated by the Nuclear Instrumentation System (N IS) power range neutron flux channels and the true power level as determined by a secondary system heat balance based value.
If necessary, the power range channels are adjusted to agree with the true power level.
This instruction also verifies availability of Leading Edge Flow Meter (LEFM) calorimetric power.
1.2.2    Requirements Fulfilled Performance of this Instruction completely fulfills Technical Specification (TS)
Surveillance Requirement (SR) 4.3.1.1.1 .B.2 (Table 4.3-1, item 2, note 2) and Technical Requirements Manual (TR) 4.3.3.15.1.
1.2.3    Modes A. Applicable Mode  - I (above 15 percent power).
B. Performance Mode 1 (above 15 percent power).
1.3      Frequency and Conditions This test must be performed at least once every 24 hours when the reactor power level is greater than 15 percent. [C.3] To ensure NIS accuracy, this test should be performed when directed by 0-GO-4 or 0-GO-S.
In the event that the Plant Computer is unavailable, provisions have been incorporated in this procedure to fulfill the SR requirements. [C.5]

.                              BALANCE COMPARISON                    Page 7 of 41 3.0    PRECAUTIONS AND LIMITATIONS A. Reactor power must remain constant (+/- 0.5%) during the performance of Sections 6.1 and 6.2. It is desirable for any required NIS adjustment be made promptly during performance of these sections.
B. Average RCS temperature (Tavg) should be maintained within 0.5&deg;F of RCS reference temperature (Tree).
C. Caution should be exercised when adjusting NIS power range instrumentation to minimize the potential for a channel trip.
D. Only one NIS channel shall be adjusted at a time. If a rate trip occurs, the channels trip signal and annunciator on panel XA-55-6A, NC-41 U or NC-41 K NIS POWER RANGE HIGH NEUTRON FLUX RATE must be cleared before proceeding to the next NIS channel.
E. Operations and Engineering should be notified if larger than normal channel adjustments (as determined by the SRO) are required to bring the power range channels into alignment with calculated core thermal power. [C.4] An operability concern may exist if excessive error in the non-conservative direction adversely impacts the NIS high flux trip setpoint. The 3% tolerance for calibration error on the high flux trip setpoints was selected using the extrapolated error from the 30% power level.
F. The reactor cores have been loaded with a low leakage loading pattern which can affect NIS Reactor Power level indications such that differences greater than the Acceptance Criteria can occur between NIS and true power level. The impact of the NIS non-linearity due to low leakage loading pattern is in the conservative direction, since NIS indicated power rises faster than true power during a power increase. 0-GO-5 may direct performance of this procedure to ensure excessive errors in the non-conservative direction do not exist. During plant restarts, Reactor Engineering may perform 0-PI-NUC-092-082.0 at 4% power to provide an initial NIS correction for startup.
G. Technical Specifications require a heat balance calculation for adjustment of the NIS when the Plant is above 15% power within 24 hours. If the Leading Edge Flow Meter (LEFM) is available, LEFM data (from U21 18 or LEFM Offline Calorimetric screen) is required to be used for the heat balance when greater than 15% power (TRM 3.3.3.15). If LEFM is not available, then Loop T data should be used between 15 and 40% power due to potential inaccuracies in the feedwater flow venturi heat balance below 40%. If LEFM is not available above 40%, then venturi-based calorimetric power (U 1118) should be used.

SUBSTITUTION OF RCS AT AT LOW POWER LEVELS (40% WITH LEFM NOT AVAILABLE)
Un it______
1.0    PERFORMANCE NOTES
: 1)  RCS delta T loops (AT&deg;) are aligned to results of a secondary-side heat balance.
Consequently, using z\Ts to adjust NIS at low power levels still satisfies the requirement to use heat balance. Loop tT is used to avoid potentially non-conservative errors in NIS power range indication if adjustments were made based upon an inaccurate secondary heat balance at a low feedwater flowrate. At low power levels the traditional secondary-side heat balance (U 1118) is not as accurate as Reactor Coolant Loop ATs.
: 2)  This appendix should NOT be used if LEFM is operable.

: 3)  Computer point 1F2261A1 is more accurate than flow indicators located in the fan rooms. If the computer point is inoperable and blowdown flows from the FISs are used in the calculation of U 1118, then expect U 1118 to indicate a different value and adjustment of NIS may be required.

NOTES
: 1)  The remaining steps determine core thermal power by manually entering calorimetric data on opposite units lOS computer. This method requires adding 3.5% to the calculated power level for additional conservatism due to greater errors associated with indicator error and readability. Therefore, power level should be reduced to less than or equal to 96.5% before performance.
: 2)  Calorimetric calculation on opposite units lOS assumes that blowdown flow is identical on each unit. This error is accounted for in the 3.5% correction factor.

STANDARD: Operator loads the DIG lA-A to 4.0 MW by intermittently placing 0-HS-82-13 to RAISE until the MW loading on 0-El-82-10A increases to 4.0 mw.
This step is critical to ensure the DG is loaded to greater than minimum to clear the exhaust system of unused fuel which could cause a fire.

,0    Excessive grounds on dc system may cause spurious actuation of components during accident conditions. If ground voltage exceeds +/- 80 volts, request Maintenance Support to locate and clear ground. Submit work order for grounds exceeding +/- 25 volts.
0    The design operating limits for the I 25v dc Vital Power System are nd 140V dc (Reference 45N703-l and 45W703-9).
I 29V dc When the 125 V Vital Battery Charger is transferred to its alternate 480 V supply (480 V Vital AC transfer switch), the load for the 480 V Shutdown Board Transformer supplying that transfer switch must be reduced by 137kW (Approximately 184 HP) if the applicable unit is in Modes 1-4. This will ensure operability of the (125V) channel equipment, for that (480 V) train.

Various breakers associated with the 125V Vital Battery System have similar breaker numbers. Caution must be used to ensure the intended component is being manipulated.
Due to vendor recommendations and calibration tolerances between the battery boards and battery chargers, voltage ranges will differ. This difference is due to instrument accuracy (TSIR 98-ICE-250-957). Voltage ranges specified by Electrical Maint. PMs should NOT be used by operations as guidelines for voltage ranges.
Identification and isolation of system grounds will be performed per 0-GO-I 0 7      and 0-PI-EBT-250-00l.0

[panels L-1 1 A and L-1 1 B].
NOTE:      ENSURE THE SM HAS GIVEN PERMISSION FOR YOU AND THE OPERATOR TO ENTER THE UNIT TRIP HAZARD AREA.
ENSURE YOU AND THE OPERATOR REMAIN AWAY FROM ALL SWITCHES.
NOTE:      This step is considered part of operator knowledge and the specific actions are not addressed by the procedure.                            SAT Cue:        Inform the operator that the as found indication is that the auto            UNSAT green light is illuminated and the controller output needle is to the far right.
NOTE:      LCV-3-148 controller is located on panel L-IIB.
Cue:        1. if the manual button is depressed, inform the operator that the amber light illuminates and the auto green light goes out.
: 2. Controller output needle is to the far right.
: 3. When the operator looks at 1-FI-3-147C (1-L-10 panel) or calls, MCR: Flow is still at 200 gpm to the # 3 SIG.
STANDARD: The operator presses the manual button on 1-LIC-3-148 (Loop 3) and increases the output (pushes button on the bottom of the controller to the right) to cause the valve to Close (or verifies output is full right).
Looks at Fl-3-1 47C or Checks with the MCR to see if flow is reduced to the #3 SIG. (The operator may elect not to manipulate the controller by stating that the controller output is already indicating fully closed.)
NOTE: This starts the alternate path STEP 6.:      If Step 4.3.1 has restored MD AFW flow, THEN:                                      SAT UN SAT STANDARD: Operator should N/A this step.
STEP 7.:      Establish communications with U-i MCR UO.                                          SAT U NSAT Cue:      If guidance is requested, direct AUO to locally isolate AFW flow to
              #3 SIG per EA-3-10.
STANDARD: Operator establishes communications with U-i MCR UO.
 
JPM Plant J Page 7 of 8 Rev. 0 Job Performance Checklist:
STEP/STANDARD                                    SAT!UNSAT STEP 8.:        Close upstream or downstream AFW LCV isolation valve for #3 SIG              SAT UNSAT Cue:        Valve handwheel moves several turns in the clockwise direction.
IF operator calls MCR: Give AFW flow to #3 S/G as zero gpm.
Critical Step NOTE:      VLV-3-826 is at Aux Bldg, elev 714, AFW mezzanine VLV-3-834 is above WVVR entrance.
STANDARD: Operator unlocks and closes VLV-3-826, or VLV-3-834 for # 3 SIG.
This step is critical to isolate the flowpath of the failed open valve.
STEP 9.:        NOTIFY UO to ensure MD AFW pumps running.                                    SAT UNSAT Both MDADW pumps are running.
STANDARD: Operator checks with Unit 1 UO to ensure pumps running.
STEP 10        CONTROL S/G level as directed by UO by throttling AFW LCV isolation          SAT valve UNSAT Cue:        Roll play as UO and have the operator throttle open the valve previously closed, 3 turns open. After the adjustment is simulated, state flow is now approx 20 gpm and no further            Critical Step manipulations will be needed.
STANDARD: Operator simulates turning valve handwheel 3 turns to the right to make adjustments as necessary to 3-826 or 3-834.
This step is critical to set the required flow to maintain adequate heat sink.
STEP 11.:      Notify UO to operate pump recirculation valves FCV-3-400, 401.              SAT Cue:        Role play as UO and report that recirculation valves have been              UNSAT operated STANDARD: Operator informs the UO to operate valves.

GASEOUS PROCESS RADIATION                    2-SO 2 MONITORING SYSTEM                      Rev: 37 Page 8 of 75 PRECAUTIONS AND LIMITATIONS Failure to observe all posted radiation control requirements may lead to unnecessary radiation absorbed doses.
Pump damage may occur from excessive heat if pumps are isolated, either manually or automatically, with the pump running.
Rad monitors which can initiate an Engineered Safety Feature (ESF) Actuation shall be blocked before any maintenance activity, functional test, or return to service is performed. [C.1]
Do not block any rad monitor that has a redundant monitor unless that redundant monitor is operable.
(?JTo prevent unmonitored releases, with one unit in Mode 1, 2, or 3 and the other in Mode 4, 5, or 6, Shield Building Vent Monitor for shutdown unit is required to be operable to satisfy NUREG-0737 and FSAR Post Accident Sampling requirements the operating unit. [C.4]
Action 28 of LCD 3.3.3.1 and action 19 of LCD 3.3.2, Table 3.3-3 must be complied with before blocking 2-RM-90-130 and 2-RM-90-131 simultaneously during Modes 2,3,4, cr6.
Moisture accumulation in the 2-RM-90-106 and 112 rad monitors pump supply lines will occur if the heat trace circuit is turned OFF or has a break in the wiring circuit.
The heat trace thermostat will maintain approximately 110&deg;F on the monitors pump supply lines. This temperature will keep the warm, sometimes humid, containment sample air which passes through the cool Aux. Bldg to the rad monitors above its dew point.
Either 2-RM-90-99 or 2-RM-90-1 19 must be in service to monitor the low range of F    the Condenser Vacuum Exhaust. Both monitors should not be in service at the me time for extended periods, due to flow limitations.
(42-RM-90-1o6/2-RM-9o-4o0 local sample pump handswitches have AUTO-OFF HAND positions. Normally AUTO position is used if starting/stopping pumps from the MCR (2-Rl-90-106AJ2-RI-90-400A). Using HAND position bypasses MCR start/stop capability.

            .ction 19 of LCO 3.3.2, Table 3.3-3 must be complied with before blocking 1-RE-90-130 and 1-RE-90-131 simultaneously during Modes 1,2,3,4, or6.
        ,1isture accumulation in the 1-90-1 06 and 112 rad monitors pump supply
      ,V lines will occur if the heat trace circuit is turned OFF or has a break in the wiring circuit. The heat trace thermostat will maintain approximately 110&deg;F on the monitors pump supply lines. This temperature will keep the warm, sometimes humid, containment sample air which passes through the cool Aux. Bldg to the rad monitors above its dew point.
4ther 1-RM-90-99 or 1-RM-90-119 must be in service to monitor the low range of the Condenser Vacuum Exhaust. Both monitors should not be in service at the same time for extended periods, due to flow limitations.
        ,.    -RE-90-106/1-RE-90-400 local sample pump handswitches have AUTO-OFF HAND positions. Normally the AUTO position is used if starting/stopping the pump from the MCR (1-RI-90-106A/1-RI-90-400A). Using HAND position bypasses MCR start/stop capability.

SQN CONTROL ROD DRIVE SYSTEM 0-SO-85-1 1,2 Rev 34 Page 6 of 80 3.0 PRECAUTIONS AND LIMITATIONS A. Rod thermal lock-up is NOT a concern when the reactor trip breakers are OPEN. If reactor trip breakers are CLOSED and an RCS cooldown of greater than 50°F is planned, the shutdown and control banks should be withdrawn at least 5 steps each. This will limit the possibility of thermal lock up of the rods. This does not apply if performing sections 8.5 or 8.6.

B. If both MG sets are to be shutdown, the control rods and shutdown rods shall be inserted in the core and the reactor trip breakers OPEN prior to shutting down the MG sets.

C. Reactor Trip Breakers shall NOT be closed while in Mode 3 unless in compliance with LCO 3.4.1.2.

D. Failure to perform 1,2-Pl-IFT-099-0P4.0, Verification of P4 Contacts could result in the prevention of AUTO SI if required.

E. Under normal conditions, the control rod banks must be withdrawn and inserted in the prescribed sequence. For withdrawal the sequence is Shutdown Bank A, Shutdown Bank B, Shutdown Bank C, Shutdown Bank D, Control Bank A, Control Bank B, Control Bank C, and Control Bank D. The insertion sequence is the reverse of the withdrawal sequence.

F. For manual bank sequencing, the prescribed withdrawal and insertion sequence should be followed. Rod motion of the correct bank should be monitored by observing the group step counters and the rod position indicators.

G. During Control Rod withdrawal, the Control Banks should be monitored for bank overlap.

H. The control banks must be maintained above their respective insertion limits (Low-Low Alarm to ensure adequate shutdown in the event of a reactor trip, to ensure that maximum possible ejected rod reactivity limits are maintained and to ensure acceptable core power distributions.

I. Before withdrawing any rod bank from the fully inserted position, the group step counters and the rod position indicators for that bank must be at zero steps.

J. Deleted K. RPIs and step counters shall be maintained within limits per TS 3.1.3.1 and 3.1.3.2.

L. The Control Rods shall NOT be stepped or tripped unless the RCS pressure is at least 100 psig.

M. Rod movement without the CRDM fans aligned to the Reactor Vessel shroud is allowed, provided that the RCS temperatures are less than 350° F.

N. When RCS temperatures are greater than 350° F, continuous rod motion shall comply with these restrictions:

CRDM OUTLET ROD MOTION LIMITS TEMPERATURE 190°F 10 minutes ON 20 minutes OFF 200°F 6 minutes ON 24 minutes OFF Time limitations are due to a lower air flow rate of 48,000 cfm across the shroud combined with a higher temperature (Reference TSIR-97-BOP-30-636 and Westinghouse Letters RIMs #B38931005806, B38930920800, and B38931 005803).

N. The following failures will render the rod control system incapable of automatic and I or manual motion without any annunciation or indication:

1) Hand switch failure; 2) relay failure, and 3) failure of both lOOv DC power supplies (PS3 and PS6) simultaneously.
0. Defeating or restoring TavglDelta T or NIS channel may cause step change in input to rod control. A delay of at least 3 minutes prior to returning rod control to automatic will allow lead/lag signal to decay off.

cautioning about CLA over-fill and over-pressurization (PCRO90001I2).Corrected steps referenced in Section 8.1 Note 1 from 13-thru-16 to 12-thru-15 (PCRO9000112).

SQN COLD LEG INJECTION 1-50-63-1 i ACCUMULATORS Rev: 47 Page 6 of 185 3.0 PRECAUTIONS AND LIMITATIONS A. Venting large volumes of nitrogen from the cold leg accumulators could displace oxygen and create a hazardous atmosphere in the No. 4 Accumulator Room.

Prior to venting a significant volume of nitrogen from the cold leg accumulators, the No. 4 Accumulator Room shall be evacuated or continuous oxygen monitoring shall be established. If evacuated, a safe atmosphere should be verified prior to restoring access.

B. Cold Leg Accumulator (CLA) room temperatures must be maintained equal to or greater than 60°F whenever the CLAs are pressurized (not open to atmosphere).

C. Tech Spec operability limit (including instrument uncertainty) for CLA borated water volume is between 7615 gallons and 7960, but Unit 1 CLA level indicators will indicate a maximum of 7956 gallons. Therefore, the CLA operability limit has been reduced to between 7615 gallons and 7955 gallons.

D. Tech Spec operability limit (including instrument uncertainty) for CLA nitrogen pressure is between 624 psig and 668 psig.

E. Do not change relief valve setpoints to allow more rapid pressurization. If Pressurization rate is inadequate, the SM should be contacted immediately for resolution.

F. Cross connection of the nitrogen or water supplies of any Cold Leg Accumulators will make the cross-tied accumulators inoperable. Do NOT cross-tie accumulators in Modes 1-3. [C.2]

G. Do not adjust pressure control valves 0-PCV-77-253 or 0-PCV-77-254.

Maintenance should be contacted for assistance if valves require adjustment.

H. To prevent premature bearing wear, SI pumps should be operated for a minimum of 20 minutes each time a pump is started.

I. To prevent brittle fracture when adding nitrogen to a CLA with accumulator pressure less than 600 psig, then the piping temperature between the nitrogen supply regulator (0-PCV-77-253 or -254) and the containment isolation valve (1-FCV-63-64) should be monitored and maintained greater than 40°F. If temperature approaches 40°F, nitrogen fill should be stopped or the flow rate reduced to maintain piping temperature greater than 40°F.

J. Anytime accumulators are filled above 7956 gallons, the upper instrument level tap will need to be purged by Instrument Maintenance Group.

K. Limiting accumulator fill to 7916 gallons during the initial fill following an outage, prevents flooding of the upper instrument level leg. After calibration the lower instrument leg is unborated water and level instrument inaccuracies result.

SQN COLD LEG INJECTION 1-SO-63-1 ACCUMULATORS Rev: 47 Page 7 of 185 3.0 PRECAUTIONS AND LIMITATIONS (continued)

L. In Modes 4, 5, and 6 (with vessel head on), CLA valves are required to be closed with motor breakers locked in OFF position unless CLA pressure is less than the maximum RCS pressure allowed by PTLR for current cold leg temperature. (LCO 3.4.12)

M. Engineering evaluation for air removal is required any time a segment of the ECCS system is drained. Ultrasonic testing may be required in order to validate air removal or to quantify any void volume that remains. This evaluation should consider whether or not the existing vent valves can completely remove all air pockets from the piping, and if not, the effect on the system of the remaining void in concert with other existing voids. During outages, the fill and vent can be verified by the subsequent performance of full flow testing. Evaluation of procedure sections can be performed in advance of actual use.

B. Maintaining 3 to 6 psig N2 gas blanket on the PRT will prevent the formation of explosive hydrogen-oxygen mixtures.

C. The PRT concentration of oxygen shall be limited to less than or equal to 2% by volume whenever the hydrogen concentration exceeds 4% by volume.

D. Over filling the PRT to solid water condition during oxygen reduction per Section 8.8 may result in failure of the PRT rupture disc.

E. The PRT pressure should be maintained <7.5 psig during normal operation. (Except during the performance of section 8.9).

F. The PRT rupture discs are rated at 85 psig.

G. The level in the PRT should be maintained at 70%. If the level increases to 88%, then decreasing level to 70% is necessary. If the level decreases to 55%, then increasing level to 70% is needed when the PRT is required to be operable.

H. Completely draining the PRT may result in gas binding the RCDT pumps.

I. Water intrusion into the waste gas vent header is possible during PRT venting operations with PRT level high. This could affect RCP seal leakoff flows and the vent capability of tanks which vent to waste gas vent header.

J. PRT level indications or alarms are not available in the Aux Control Room, thus PRT level manipulations and feed & bleed processes are unavailable.

(09001296). This is an editorial change to clarify intent.

Modified Section 5.0 Acceptance Criteria A associated with a +/-2% delta between NIS and core thermal power to reflect the Tech Spec requirement. Any channel deviating from core thermal power by more than 2.0% is required to be adjusted. Removed special message boxes from Section 6.1 that incorrectly indicated specific parameters as Acceptance Criteria. Steps 6.1[5] and 6.1[8] were modified to present the allowable deviations between NIS and core thermal power within the step rather than as Acceptance Criteria. (PER 167130)

Relocated step associated with SRO notification of requirements for testing inoperable channels to later in Section 6.1 to provide a more logical sequence. This is an alteration to an administrative requirement and is a minor change.

Modified the tables associated with Steps 6.1[5j, 6.1[7j and 6.1[8] to clarify intent as a minor change.

A note was added prior to Step 6.1[10] to clarify pre-existing intent that bulleted steps are to be marked N/A as appropriate.

Added Precaution and Limitation H regarding the potential impact of Auxiliary Instrument Room temperature on core thermal power indication (09000640).

1.0 INTRODUCTION

1.1 Purpose This Surveillance Instruction (SI) provides detailed steps for ensuring proper calibration of the power range neutron flux channels.

1.2 Scope 1.2.1 Surveillance Test to be Performed This Instruction performs a comparison between the power level calculated by the Nuclear Instrumentation System (N IS) power range neutron flux channels and the true power level as determined by a secondary system heat balance based value.

If necessary, the power range channels are adjusted to agree with the true power level.

This instruction also verifies availability of Leading Edge Flow Meter (LEFM) calorimetric power.

1.2.2 Requirements Fulfilled Performance of this Instruction completely fulfills Technical Specification (TS)

Surveillance Requirement (SR) 4.3.1.1.1 .B.2 (Table 4.3-1, item 2, note 2) and Technical Requirements Manual (TR) 4.3.3.15.1.

1.2.3 Modes A. Applicable Mode - I (above 15 percent power).

B. Performance Mode 1 (above 15 percent power).

1.3 Frequency and Conditions This test must be performed at least once every 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> when the reactor power level is greater than 15 percent. [C.3] To ensure NIS accuracy, this test should be performed when directed by 0-GO-4 or 0-GO-S.

In the event that the Plant Computer is unavailable, provisions have been incorporated in this procedure to fulfill the SR requirements. [C.5]

. BALANCE COMPARISON Page 7 of 41 3.0 PRECAUTIONS AND LIMITATIONS A. Reactor power must remain constant (+/- 0.5%) during the performance of Sections 6.1 and 6.2. It is desirable for any required NIS adjustment be made promptly during performance of these sections.

B. Average RCS temperature (Tavg) should be maintained within 0.5°F of RCS reference temperature (Tree).

C. Caution should be exercised when adjusting NIS power range instrumentation to minimize the potential for a channel trip.

D. Only one NIS channel shall be adjusted at a time. If a rate trip occurs, the channels trip signal and annunciator on panel XA-55-6A, NC-41 U or NC-41 K NIS POWER RANGE HIGH NEUTRON FLUX RATE must be cleared before proceeding to the next NIS channel.

E. Operations and Engineering should be notified if larger than normal channel adjustments (as determined by the SRO) are required to bring the power range channels into alignment with calculated core thermal power. [C.4] An operability concern may exist if excessive error in the non-conservative direction adversely impacts the NIS high flux trip setpoint. The 3% tolerance for calibration error on the high flux trip setpoints was selected using the extrapolated error from the 30% power level.

F. The reactor cores have been loaded with a low leakage loading pattern which can affect NIS Reactor Power level indications such that differences greater than the Acceptance Criteria can occur between NIS and true power level. The impact of the NIS non-linearity due to low leakage loading pattern is in the conservative direction, since NIS indicated power rises faster than true power during a power increase. 0-GO-5 may direct performance of this procedure to ensure excessive errors in the non-conservative direction do not exist. During plant restarts, Reactor Engineering may perform 0-PI-NUC-092-082.0 at 4% power to provide an initial NIS correction for startup.

G. Technical Specifications require a heat balance calculation for adjustment of the NIS when the Plant is above 15% power within 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br />. If the Leading Edge Flow Meter (LEFM) is available, LEFM data (from U21 18 or LEFM Offline Calorimetric screen) is required to be used for the heat balance when greater than 15% power (TRM 3.3.3.15). If LEFM is not available, then Loop T data should be used between 15 and 40% power due to potential inaccuracies in the feedwater flow venturi heat balance below 40%. If LEFM is not available above 40%, then venturi-based calorimetric power (U 1118) should be used.

CALCULATION OF CORE THERMAL POWER USING LEFM Unit______

NOTES

1) ICS allows two options for blowdown flows:

Option #1 (Preferred) -use point fF2261 Al which requires no operator entered data (computer automatically updates the blowdown flows).

Option #2 use manually entered S/G blowdown flow rates.

2) Computer point [F2261A] is more accurate than flow indicators located in the fan rooms. If the computer point is inoperable and blowdown flows from the FISs are used, then indicated core thermal power may be a slightly different value.

[1] ENSURE S!G blowdown flows are updated by performing the following functions on ICS:

[1.11 SELECT NSSS AND BOP.

SUBSTITUTION OF RCS AT AT LOW POWER LEVELS (40% WITH LEFM NOT AVAILABLE)

Un it______

1.0 PERFORMANCE NOTES

1) RCS delta T loops (AT°) are aligned to results of a secondary-side heat balance.

Consequently, using z\Ts to adjust NIS at low power levels still satisfies the requirement to use heat balance. Loop tT is used to avoid potentially non-conservative errors in NIS power range indication if adjustments were made based upon an inaccurate secondary heat balance at a low feedwater flowrate. At low power levels the traditional secondary-side heat balance (U 1118) is not as accurate as Reactor Coolant Loop ATs.

2) This appendix should NOT be used if LEFM is operable.

3) Computer point 1F2261A1 is more accurate than flow indicators located in the fan rooms. If the computer point is inoperable and blowdown flows from the FISs are used in the calculation of U 1118, then expect U 1118 to indicate a different value and adjustment of NIS may be required.

1) The remaining steps determine core thermal power by manually entering calorimetric data on opposite units lOS computer. This method requires adding 3.5% to the calculated power level for additional conservatism due to greater errors associated with indicator error and readability. Therefore, power level should be reduced to less than or equal to 96.5% before performance.

,0 Excessive grounds on dc system may cause spurious actuation of components during accident conditions. If ground voltage exceeds +/- 80 volts, request Maintenance Support to locate and clear ground. Submit work order for grounds exceeding +/- 25 volts.

0 The design operating limits for the I 25v dc Vital Power System are nd 140V dc (Reference 45N703-l and 45W703-9).

I 29V dc When the 125 V Vital Battery Charger is transferred to its alternate 480 V supply (480 V Vital AC transfer switch), the load for the 480 V Shutdown Board Transformer supplying that transfer switch must be reduced by 137kW (Approximately 184 HP) if the applicable unit is in Modes 1-4. This will ensure operability of the (125V) channel equipment, for that (480 V) train.

SQN 125 VOLT DC VITAL POWER SYSTEM 0-SO-250-1 Unit 0 Rev. 0043 Page 9 of 177 PRECAUTIONS AND LIMITATIONS (continued)

Various breakers associated with the 125V Vital Battery System have similar breaker numbers. Caution must be used to ensure the intended component is being manipulated.

Due to vendor recommendations and calibration tolerances between the battery boards and battery chargers, voltage ranges will differ. This difference is due to instrument accuracy (TSIR 98-ICE-250-957). Voltage ranges specified by Electrical Maint. PMs should NOT be used by operations as guidelines for voltage ranges.

JPM Plant J Page 4 of 8 Rev. 0 READ TO OPERATOR Directions to Trainee:

I will explain the initial conditions, and state the task to be performed. All steps shall be simulated for this JPM. WHEN ENTERING A UNIT TRIP HAZARD ZONE ENSURE YOU DO NOT TOUCH ANY SWITCHES WITHIN THAT ZONE. I will provide initiating cues and indicate any steps to be discussed. When you complete the task successfully, the objective for this job performance measure will be satisfied. Ensure you indicate to me when you understand your assigned task. To indicate that you have completed your assigned task return the handout sheet I provided you.

INITIAL CONDITIONS:

1. Unit 1 has experienced a Rx trip from 100% power.
2. The Unit 1 turbine-driven AFW pump has tripped off for unknown reasons.
3. During recovery from the Rx trip, the control room operator was unable to control AFW flow to SIG 3.

4 The level control valve to loop 3 S/G will NOT close from the MCR.

5 All narrow range SIG levels are 15%.

INITIATING CUES:

1. The Unit 1 US has directed you, the control room AUO to establish control of the 1 B-B motor-driven AFW pump LCV for S/G # 3, using EA-3-1 0.
2. Inform the Unit I US when control of flow to SIG # 3 has been established.

STEP/STAN DARD SATIU NSAT STEP 1.: Obtain a copy of the appropriate procedure. SAT U N SAT STANDARD: Operator obtains a copy of EA-3-10.

Start Time STEP 2.: SELECT applicable unit and pump. SAT UNSAT STANDARD: Operator checks Unit 1 and MD AFW Pump B-B.

STEP 3.: If starting MD AFW pump locally.... SAT UNSAT IF asked: Pump is running.

STANDARD: Operator N/As this step.

STEP 4.: IF MD AFW LCV valve or controller failure has occurred, THEN GO TO SAT Section 4.3.

UNSAT STANDARD: Operator goes to section 4.3.

STEPISTANDARD SATIUNSAT STEP 5.: ATTEMPT to control AFW LCVs from the Auxiliary Control Room

[panels L-1 1 A and L-1 1 B].

NOTE: ENSURE THE SM HAS GIVEN PERMISSION FOR YOU AND THE OPERATOR TO ENTER THE UNIT TRIP HAZARD AREA.

ENSURE YOU AND THE OPERATOR REMAIN AWAY FROM ALL SWITCHES.

NOTE: This step is considered part of operator knowledge and the specific actions are not addressed by the procedure. SAT Cue: Inform the operator that the as found indication is that the auto UNSAT green light is illuminated and the controller output needle is to the far right.

NOTE: LCV-3-148 controller is located on panel L-IIB.

Cue: 1. if the manual button is depressed, inform the operator that the amber light illuminates and the auto green light goes out.

2. Controller output needle is to the far right.
3. When the operator looks at 1-FI-3-147C (1-L-10 panel) or calls, MCR: Flow is still at 200 gpm to the # 3 SIG.

STANDARD: The operator presses the manual button on 1-LIC-3-148 (Loop 3) and increases the output (pushes button on the bottom of the controller to the right) to cause the valve to Close (or verifies output is full right).

Looks at Fl-3-1 47C or Checks with the MCR to see if flow is reduced to the #3 SIG. (The operator may elect not to manipulate the controller by stating that the controller output is already indicating fully closed.)

NOTE: This starts the alternate path STEP 6.: If Step 4.3.1 has restored MD AFW flow, THEN: SAT UN SAT STANDARD: Operator should N/A this step.

STEP 7.: Establish communications with U-i MCR UO. SAT U NSAT Cue: If guidance is requested, direct AUO to locally isolate AFW flow to

  1. 3 SIG per EA-3-10.

STANDARD: Operator establishes communications with U-i MCR UO.

JPM Plant J Page 7 of 8 Rev. 0 Job Performance Checklist:

STEP/STANDARD SAT!UNSAT STEP 8.: Close upstream or downstream AFW LCV isolation valve for #3 SIG SAT UNSAT Cue: Valve handwheel moves several turns in the clockwise direction.

IF operator calls MCR: Give AFW flow to #3 S/G as zero gpm.

Critical Step NOTE: VLV-3-826 is at Aux Bldg, elev 714, AFW mezzanine VLV-3-834 is above WVVR entrance.

STANDARD: Operator unlocks and closes VLV-3-826, or VLV-3-834 for # 3 SIG.

This step is critical to isolate the flowpath of the failed open valve.

STEP 9.: NOTIFY UO to ensure MD AFW pumps running. SAT UNSAT Both MDADW pumps are running.

STANDARD: Operator checks with Unit 1 UO to ensure pumps running.

STEP 10 CONTROL S/G level as directed by UO by throttling AFW LCV isolation SAT valve UNSAT Cue: Roll play as UO and have the operator throttle open the valve previously closed, 3 turns open. After the adjustment is simulated, state flow is now approx 20 gpm and no further Critical Step manipulations will be needed.

STANDARD: Operator simulates turning valve handwheel 3 turns to the right to make adjustments as necessary to 3-826 or 3-834.

This step is critical to set the required flow to maintain adequate heat sink.

STEP 11.: Notify UO to operate pump recirculation valves FCV-3-400, 401. SAT Cue: Role play as UO and report that recirculation valves have been UNSAT operated STANDARD: Operator informs the UO to operate valves.

GASEOUS PROCESS RADIATION 2-SO 2 MONITORING SYSTEM Rev: 37 Page 8 of 75 PRECAUTIONS AND LIMITATIONS Failure to observe all posted radiation control requirements may lead to unnecessary radiation absorbed doses.

Pump damage may occur from excessive heat if pumps are isolated, either manually or automatically, with the pump running.

Rad monitors which can initiate an Engineered Safety Feature (ESF) Actuation shall be blocked before any maintenance activity, functional test, or return to service is performed. [C.1]

Do not block any rad monitor that has a redundant monitor unless that redundant monitor is operable.

(?JTo prevent unmonitored releases, with one unit in Mode 1, 2, or 3 and the other in Mode 4, 5, or 6, Shield Building Vent Monitor for shutdown unit is required to be operable to satisfy NUREG-0737 and FSAR Post Accident Sampling requirements the operating unit. [C.4]

Action 28 of LCD 3.3.3.1 and action 19 of LCD 3.3.2, Table 3.3-3 must be complied with before blocking 2-RM-90-130 and 2-RM-90-131 simultaneously during Modes 2,3,4, cr6.

Moisture accumulation in the 2-RM-90-106 and 112 rad monitors pump supply lines will occur if the heat trace circuit is turned OFF or has a break in the wiring circuit.

The heat trace thermostat will maintain approximately 110°F on the monitors pump supply lines. This temperature will keep the warm, sometimes humid, containment sample air which passes through the cool Aux. Bldg to the rad monitors above its dew point.

Either 2-RM-90-99 or 2-RM-90-1 19 must be in service to monitor the low range of F the Condenser Vacuum Exhaust. Both monitors should not be in service at the me time for extended periods, due to flow limitations.

(42-RM-90-1o6/2-RM-9o-4o0 local sample pump handswitches have AUTO-OFF HAND positions. Normally AUTO position is used if starting/stopping pumps from the MCR (2-Rl-90-106AJ2-RI-90-400A). Using HAND position bypasses MCR start/stop capability.

damage may occur from excessive heat if pumps are isolated, either manually or automatically, with the pump running.

Monitors which can initiate an Engineered Safety Feature (ESF) 2- Actuation shall be blocked before any maintenance activity, functional test, or return to service is performed. [C.I]

not block any Rad Monitor that has a redundant monitor unless that 7 redundant monitor is operable.

prevent unmonitored releases, with one unit in Mode 1, 2, or 3 and the other unit in Mode 4, 5, or 6, Shield Building Vent Monitor for shutdown unit is required to be operable to satisfy NUREG-0737 and FSAR Post Accident Sampling requirements for the operating unit. [C.4]

.ction 19 of LCO 3.3.2, Table 3.3-3 must be complied with before blocking 1-RE-90-130 and 1-RE-90-131 simultaneously during Modes 1,2,3,4, or6.

,1isture accumulation in the 1-90-1 06 and 112 rad monitors pump supply

,V lines will occur if the heat trace circuit is turned OFF or has a break in the wiring circuit. The heat trace thermostat will maintain approximately 110°F on the monitors pump supply lines. This temperature will keep the warm, sometimes humid, containment sample air which passes through the cool Aux. Bldg to the rad monitors above its dew point.

4ther 1-RM-90-99 or 1-RM-90-119 must be in service to monitor the low range of the Condenser Vacuum Exhaust. Both monitors should not be in service at the same time for extended periods, due to flow limitations.

,. -RE-90-106/1-RE-90-400 local sample pump handswitches have AUTO-OFF HAND positions. Normally the AUTO position is used if starting/stopping the pump from the MCR (1-RI-90-106A/1-RI-90-400A). Using HAND position bypasses MCR start/stop capability.
