Reactor Engineering should be contacted for guidance on core operating recommendations during unusual power maneuvers such as startup during end of core life. c.iij TRM 3.3.3.15 requires LEFM core thermal power (U21 18) to be used to perform 0-Sl-OPS-092-078.O above 15% reactor power. LEFM indication is available if the following conditions are met:
- LEFM status NORMAL on ICS Calorimetric Data scree n
- LEFM core thermal power (ICS point U21 18) shows good (green) data.
- LEFM MFW header temp (ICS p.oint T8502MA) greater than 250°F.
If LEFM indication is NOT available above 15% reactor pow er, then TR 3.3.3.15 action must be entered.
) During startup, NIS power range indication may be reading 1 significantly higher than true power until calibration adjustments are made. The following should be used to determine the most accurate indication for comparis on with NIS:
- When reactor power is less than or equal to 15%, use average loop iT (U0485).
- When reactor power is greater than 15%, use LEFM core thermal power indication (U21 18). If LEFM is NOT available, then continue using average loop zT up to 40%. (Ui 118 will be used above 40% with LEFM unavailable).
The boron concentration in the pressurizer should be maintained within 50 ppm of the RCS by use of pressurizer heaters and spray. Pressurizer enclosure temperature should be maintained less than 150°F. Rapid changes in pressurizer enclosure temperature may result in pressurizer safety valve simmer.
SQN POWER ASCENSION FROM LESS Unit I & 2 0-GO-4 THAN 5% REACTOR POWER TO 30% Rev, 0076 REACTOR POWER Page 9 of III 31 Precautions (continued) The low pressure turbine steam inlet tem perature should be limited to 400°F when unit load is less than 10%. When redu cing load, the reheater control valves should be adjusted to limit reheater outle t temperature to a maximum of 400°F within approximately 15 minutes after reaching 10% load. Do NOT pass steam through the turbine with the rotor at rest. The turbine should be on turning gear anytime the main stea m lines are pressurized up to turbine stop valves. Change in load should be controlled in accord ance with load changing curves of Tl-28, Figures 6 and 7. Tl-28, Figure 6 is design ed to limit the maximum rotor stress during the entire program of acceleration, synchronizing, holding at minimum load, followed by raising load to full capability. The recommended time periods for each phase of the program are determined by the measured first-stage metal temperature at the time of start ing. The turbine should be operated in IMP OUT control during normal unit operation. iMP IN operation results in sys tem swings arid should only be used during the performance of valve tests. (W lette r GP 89-1 55, RIMS S57 901-26 972) The Predictive Maintenance Engineer (PDM) shou ld be contacted following a unit trip so that he may determine if local vibra tion monitoring of the Turbine-Generator, by the PDM staff should be performed when the unit is restarted. Normally, monitoring is necessary follo wing major maintenance outage on the turbine-generator, a refueling outage, a or after a plant trip which was due to a turbine initiated trip or a gen erator electrical initiated trip. Two hours lead time prior to the initial turbine roll is necessary to ensure that the PDM staff is onsite to monItor the start-up. The Ma intenance Shift Supervisor (MSS) has the telephone numbers and pag er numbers for the Predictive Maintenance Engineer and the Supervisor for the PDM staff. Any off frequency turbine operation is to be reported to the Component Engineering Group Vibration Engineer for record keep ing. The report will include duration and magnitude of off-frequency operation. Operation at off-frequencies is to be avoided in order to preven t the probable occurrence of turbine blade resonance. Prolonged periods of operatton at certain off-design frequencies could cause excessive vibratory stre sses which could eventually generate fatigue cracking in the blades. Off-frequ ency operation is permitted to the degree and time limit specified on the chart Off-Frequency Turbine Operation, Figure 14 of Tl-28.
T SQN Unit I & 2 POWER ASCENSION FROM LESS 0-GO-4 THAN 5% REACTOR POWER TO 30% Rev. 0076 S REACTOR POWER Page 10 of 111 3.1 Precautions (continued) The valve position limiter should be periodical ly positioned approximately 10% above governor control indications (keeps gove rnor valves off of the limiter) as turbine load is raised. This prevents inadverte nt load rises by limiting governor valve opening and allows a faster response of the runback feature which ensures main feedwater system will supp ly the required amount of flow. The position of control rod bank D should norm ally be 215 steps when power level is steady state at or above 85% RTP. At steady state power levels below 85%, control bank D should normally be 165 steps. If rod position is more than 2 steps below this guidance for long term
, then an impact to safety analysis assumptions may occur. Long term will be defined/determined by Reactor Engineering and the Fuel Vendor.
At low power levels, the LP Heaters may be unba lanced in extraction steam supply use and heat pickup across the conden sate side of the heater string. This condition should correct itself as the unit approaches 45-50% Turbine Power. (REF. REF 99-003789-000) 0-Pl-OPS-035-001 .0 should be performed prior to turbine restart when recommended by engineering, following maintenan ce or plant activities in which the generator was depressurized durin g a forced outage, or after a refueling outage. 0-P(-OPS-035-001 .0 provides verification and adjustment of the Seal Oil System normal and backup regulator
- s. (REF PER-04-24237-000)
The turbine should not be on hold at 1800 rpm for long er than 2 hours when the generator is not synchronized to the grid. Longer than 2 hours will cause overheating of the turbine blading (last row).

SQN BORON CONCENTRATION CONTROL 0SO-62-7 1,2 Rev. 62 Page7of 201 3.0 PRECAUTIONS AND LIMITATIONS The mode selector switch should be returned to the AUTO mak eup mode after any dilution or boration operation. The control switch must be turned to START in order for the auto makeup to function. At least one Reactor Coolant Pump or one RHR Pump mus be t in operation during dilution operations. [C.6] Maintain Pressurizer boron concentration within 50 ppm of react or coolant loop boron concentration. This can be accomplished by turning press urizer heaters on and allowing sprays to maintain RCS pressure within program. If Normal Spray is NOT available, then Auxiliary Spray should be used (1, 2-SO-62-1
) in conjunction with pressurizer backup heaters.
Axial flux difference should be maintained within limits by using the control bank of rods while changing boron concentration. Prior to making a positive reactivity change, Tech Specs and TRM should be referenced to ensure the unit is not in a LCO action that proh ibits a positive reactivity change. (CI] A boron sample should be obtained whenever reactor makeup water is added to the VCT, unless the unit is at power and results of the makeup are as expected. When making an RCS dilution of 3000 gallons, it should be done in batches with an RCS boron concentration verification at the halfway poin t (e.g., 1500 gallons). Allow at least 15 minutes between batches. fC.5] [0.7] Simultaneous makeup to the RWST and the RCS should be avoided to prevent the possibility of injecting unborated (or under borated) water into the core

[0.6] [0.7] Reactivity balance calculations are required for any power changes more than 1 %, except when immediate boration is required to maintain rods above the insertion limit or as required during an Rapid Shutdown or Load Reduction (AOP-C.03) or dropped/misaligned rod recovery (AOP-C.01). Although stated in the procedure that only one calculation is required for a major change in Reactor Power, calculations should be current and take into account the time dependency of parameters used in the calculation. [e.g. one calculation to reduce RX power to 70% power to remove a MFP is acceptable]. in the event of a large power manipulation (GO startup or shutdown) several calculations will be required. A calculation should be performed for the ascension to 30% Reactor power, another for an ascension to 50%, and so on. These calculations may be correlated to GO plateaus.
SQN BORON CONCENTRATION CONTROL 0-SO-62-7 1,2 Rev. 62 Page8of2Ol 3.0 PRECAUTIONS AND LIMITATIONS (CONTIN UED) ZBoric Acid Controller adjustment is required for B-i 0 depletion for auto manual makeup to improve the accuracy of the blen matic and

An unanticipated power change greater than 5 MW T, rod motion greater than I step (in or out), or TAVG greater than 0.5°F, require an SR and should be evaluated as a potential reactivity management event per NPG-SPP-lO.4, Reactivity Management Program. Boron concentration measurement inaccuracies and integrator calibration tolerance may result in a small difference between RCS boron concentration and blend boron concentration. This may result in a small change in Tavg (114°F) and thermal power (by a few megawatts) after makeup. Manual Makeup (Section 6.5) of approximately 200 gallo ns or less is preferred over allowing the system to automatically make up in Modes I and 2. Performing manual makeup and limiting the volume of makeup is preferred to reduce the impact on reactivity, RCP seal performance (due to reduced pressureltemperature transients) and RCS chemistry (due to reduced VCT pressure changes). During transient conditions, emergencies, or during plant cool down, automatic makeup may be used as necessary. The potential exists that the blender piping contains prim ary water. This will result in a dilution and a small reactivity addition. Completely emptying the BATs for all valve work is not required to establish a safe work boundary.

If reactor trip breakers are CLOSED and an RCS cooldown of greater than 50°F is planned, the shutdown and cont rol banks should be withdrawn at least 5 steps each. This will limit the possibilit y of thermal Iock-up of the rods. This does not apply if performing section s 8.5 or 8.6. If both MG sets are to be shutdown, the cont rol rods and shutdown rods shall Mkbe inserted in the core and the reactor trip breakers OPE down the MG sets. N prior to shutting Reactor Trip Breakers shall NOT be closed whil e in Mode 3 unless in compliance with LCO 3.4.1.2. Failure to perform I ,2-Pl-IFT-099-0P4.O, Veri 7 fication of P4 Contacts could result in the prevention of AUTO SI if required. Under normal conditions, the control rod bank s must be withdrawn and inserted in the prescribed sequence. For withdraw al the sequence is Shutdown Bank A, Shutdown Bank B, Shutdown Bank C, Shutdow n Bank D, Control Bank A, Control Bank B, Control Bank C, and Control Bank D. The insertion sequence is the reverse of the withdrawal sequen ce. 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. During Control Rod withdrawal, the Control Bank s should be monitored for bank overlap. 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. Before withdrawing any rod bank from the fully inserted position, the group step counters and the rod position indicators for that bank mus t be at zero steps. RPls and step counters shall be maintained within limits per TS 3.1.3.1 and 3.1.3.2. The Control Rods shall NOT be stepped or tripped unless the RCS pre ssure is at least 100 psig.

- 1) MFW Bypass valves will be using single element control, which means the desired SO level setpoint will be compared to the actual SG level until adequate steam and feeciwater flow are available. Single Element to Three Element control transition occurs at 13% RIP (.494E6 LBMIHR steam flow per loop).
- 2) MFW Reg valves may have a positive deviation if reactor power is in the upper range of the control band (1-4%) in the following step.

Raise plant power to 13-15% RTP Time I Position j Applicants Actions or Behavior NOTES
- 1) Actions effecting reactivity are directed in the following step. O-SO-62-7 requirements shall be adhered to for reactivity changes (i.e. reactivity balance, amounts of boric acid or water). All appropriate verifications and peer checks shall be utilized during performance.
- 2) Recommended dilution rate is 50 to 75 gallon batches every 12 to 15 minutes for a steady power rise. Rod movement should be limited to 112 step increments approximately every 1 1/2 minutes. Dilution and rod movement rates may be adjusted depending on SG level control stability.
- 3) :atpj Rod withdrawal and I or dilution requirements may be significantly impacted by the change in core reactivity due to changing Xenon concentration.
[3] INITIATE a methodical and deliberate reactor power ascent by CREW manual adjustment of the control banks or by diluting the RCS. Examiner Note: The following Steps are from 0-SO-62-7 Boron Concentration Control, Section 6.2, Dilute CAUTION I When making an RCS dilution of > 3000 gallons, it should be done in batches with an RCS boron concentration verification at the halfway point (e.g., 1500 gallons). Allow at least 15 minutes between batches. [C.5] [C.7] CAUTION 2 Returning the Boric Acid Blender to service after unplugging, cleaning, or maintenance on the Boric Acid System could introduce debris, sludge, air or chunks of solidified boron into the CCP suction resulting in pump damage. Extreme care must be exercised to properly flush the Boric Acid Blender system following an outage. [C.21 NOTE I If an excessive amount of dilution is required (plant startup), the pressurizer heaters should be energized to cause pressurizer spray operation for equalizing boron concentration in RCS and pressurizer. NOTE 2 Dilute mode will be used anytime a long-term positive reactivity addition is desired. The operator should use the normal dilute mode whenever conditions permit. Examiner Note: Dilutions will be performed based on the Reactor Engineering provided Reactivity Spreadsheet; based on 0-GO-4 Notes, recommended dilution rate is 50 to 75 gallon batches every 12 to 15 minutes for a steady power increase. During subsequent power escalation, large volume dilutions will be divided evenly over each hour as determined by the crew [i.e.: one-third, one-quarter of the volume over each hours period (e.g.: -P60 gallons, 4 times per hour for 240 gallons for the first hour)]. Examiner Note: use time compression as required to facilitate power increase. ATC [1] ENSURE unit is ] in a Tech Spec or TRM action that prohibits positive reactivity additions. [C.1] NOTE: HUT level increase of 1% is equal to 1380 gallons (Tl-28 fig. 34).

CAUTION 2 If reactor power is above P4 but below 5% power, Tech Specs require restoring inoperable channel prior to raising power above 5%. NOTE I If Intermediate Range channel is failed high, reducing reactor power to less than P-lU (10%) will result in a reactor trip. If control power is available, this condition will be corrected when the channel is bypassed in Step 6.
