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 (NIS) 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) 4.3.1.1.1.8.2 (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 - 1 (above 15 percent power).
8.
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 0-80-4 or 0-80-5.
In the event that the Plant Computer is unavailable, provisions have been
incorporated in this procedure to fulfill the SR requirements. [C.5]

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 (Tref).
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
channel's 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.

PRECAUTIONS AND LIMITATIONS (Continued)
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, ICS point U2118 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 (U1118) should be used.

SUBSTITUTION OF RCS flT AT LOW POWER LEVELS
(:s: 40% WITH LEFM NOT AVAILABLE)
RCS delta T loops (flTO) are aligned to results of a secondary-side
heat balance. Consequently, using flTs to adjust NIS at low power
levels still satisfies the requirement to use heat balance. Loop flT 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 flTs.

INTRODUCTION
1.1
Purpose
This instruction provides steps to ensure that valves listed in Surveillance
Requirement 4.9.1.3 (Boron Concentration Control During Refueling Operations)
are maintained in the closed position and maintained under administrative control
during refueling operations. The control of the valves listed in SR 4.9.1.3 will
prevent any uncontrolled boron dilution accident by isolating all possible sources
of unborated water to the RCS. Administrative control is maintained by the
SPP-10.2, Clearance Program.
This procedure may also be performed as *an option to prevent an uncontrolled
RCS dilution during RHR system operation (modes 4 or 5).
1.2
Scope
1.2.1
Operability Test to be Performed
This surveillance provides valve alignment checklists that will isolate and
administratively control all potential flowpaths of unborated water sources to
the Reactor Coolant System. The checklists (Appendix A thru D) represent the
valve combinations specified by SR 4.9.1.3 (LCO 3.9.1) that are required to be
verified closed and under administrative control during refueling operations.
This Surveillance may be performed under the following conditions:
A. Mode 6 (Refuel Operations)
To prevent an uncontrolled RCS dilution during refueling by ensuring all
available RCS dilution paths are isolated and placed under administrative
control. The isolation of dilution flow paths is required by SR 4.9.1.3 and
partially fulfills the plant technical specification requirements of LCO 3.9.1.
B. Modes 4 &5
To prevent an uncontrolled RCS dilution at cold or hot shutdown conditions while
on the RHRSystem by implementing one of the following options:
- 1.
The RCS is borated to a concentration that would allow sufficient operator
response time to stop the dilution. The adequacy of RCS is boron
concentration is determined by 0-SI-NUC-OOO-038.0, Shutdown Margin.

1.2.1
Operability Test to be Performed (Continued)
2.
The shutdown rods are withdrawn by 10/0 delta K/K to provide positive operator
indication of a dilution accident in progress (SRM reactor trip) and additional
time for operator termination of the event. If the shutdown rods are withdrawn
then O-SI-NUC-OOO-038.0, Shutdown Margin must be completed to verify
K~eff remains less than .99 to prevent a mode change.
3.
The RHR system is isolated from the RCS, FCV-74-1 or FCV-74-2 closed.
4.
The available RCS dilution paths are closed and placed under administrative
control.
1.2.2
RequirementsFulfilied
A.
Mode 6 (Refueling)
Performed to partially fulfill the plant technical specification requirements of
LCO 3.9.1 which requires one of the valve combinations specified in SR
4.9.1.3 to be closed and under administrative control.
B. Modes 4 & 5 RHR Operation
Westinghouse letter S53 860813 665 expressed concerns and provided
recommended actions reqardinq the potential for an inadvertent boron
dilution event at cold or hat shutdown conditions while on the RHR System.
Recommended actions to preclude an inadvertent boron dilution event while
in hot or cold shutdown are listed in section 1.2.1, "Operability Test to be
Performed." The isolation of dilution flow paths provides one option for
preventing dilution of the ReS at Cold or Hot Shutdown conditions while on
the Residual Heat Removal System.

NOTE 4
Transferring 480V Shutdown Board 2B2-B may result in
closing of the Main MSR Control Valves.
480V Shutdown Board 2B2-B is normally fed from the
6900/480V Transformer 2B2-B. Its alternate power source is
the 6900/480V Transformer 2B-B.
The alternate supply transformer 2B-B is designed to supply
only one board at a time. Since the breakers are NOT
interlocked, the operator must ensure both breakers are
NOT closed simultaneously.
Performance of this section will require more
than one individual for actual board transfer.
Expect alarm on associated Vital Inverter due
to " Isolimiter Output Voltage High".
