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 0.00667 hours 3.968254e-5 weeks 9.132e-6 months 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 0.00667 hours 3.968254e-5 weeks 9.132e-6 months . 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.

Page 4 of 12

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.

PRECAUTIONS AND LIMITATIONS

A. A specific clearance must be issued to include all valves listed in the appendix

that is performed. This ensures positive administrative control of valving which

could result in an uncontrolled dilution event.

B. After the initial performance of this instruction the clearance procedure may be

utilized to verify valve positions in subsequent performances.

C. The clearance procedure may be utilized for verification per SPP-10.3 for

removal and return to normal of equipment.

D. Failure to observe all posted RADCON requirements may lead to unnecessary

Radiation Absorbed Doses.

NOTE 3

Prior to energizing an electrical board after work has been

performed on it, the SM/SM representative must perform a

walkdown of the board. Operations may require the work

directors to assist in the walkdown.

480V Shutdown Board 2B2-B is normally supplied from

2B-B 6900V Shutdown Board. This Instruction section

provides for alternate source feed establishment.

All steps in this section refer to 480V Shutdown Board

2B2-B unless specifically stated otherwise.

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.
