1.0 INTRODUCTION

1.1 Purpose This Instruction provides detailed steps to perform a Reactor Coolant System (RCS) water inventory balance.

1.2 Scope 1.2.1 Operability Test to be Performed Operations that could affect RCS water inventory (makeup and sampling) are terminated and the RCS is stabilized. With the RCS stable, parameters such as temperature, pressure, and associated tank levels are measured at one hour or greater intervals. When at least two sets of data have been collected, identified and unidentified leakages are calculated using the rate of change between the data sets.

Then, the calculated leakage rates are compared to values in Technical Specification Limiting Condition for Operation (LCO) 3.4.13 to determine RCS 4

operability.

The final RCS power level must be within +/- 1 .0% of the initial RCS power level or the final data is VOID and must be retaken.

Makeup to the Volume Control Tank (VCT) is isolated and VCT level is expected to decrease during this SI. If VCT level falls to 20% or low VCT level alarm annunciates before final data is recorded, makeup to the VCT will be required and the test will have to be voided and reperformed.

The Reactor Coolant Drain Tank (RCDT) pumps are placed in PULL-TO-LOCK with 1-FCV-68-310, PRT DRAIN, closed. At the same time, RCDT and Pressurizer Relief Tank (PRT) levels are expected to increase. If PRT or RCDT high level alarm annunciates before final data is recorded, pump-down of the PRT or RCDT will be required and the test will have to be voided and reperformed.

Instruments such as PZR pressure and level or any other instruments used by the RCS Inventory Program that are removed from service during the performance of this SI will cause the quality to be bad on the final data sheet.

Any revisions to this SI will require coordination with the Computer Engineering Group to change the SI revision level displayed on the ICS Water Inventory Balance screen.

Any revisions or modifications to this procedure that affect the water inventory balance calculation or that could affect the ICS software will require a Computer Software Service Request (SSR) per SPP-2.6 to make the applicable software changes to the ICS Water Inventory Balance.

If any of the following events occur during performance of Section 6.0 the data is VOID and the test must be restarted after initial conditions are reestablished:

Any instrument or computer data point used to obtain initial data is NOT available for final data.

Emergency boration.

Diversion of letdown to the hold up tanks.

Sampling the RCS or making chemical additions to the RCS (with the exception of RCS Zinc Injection).

PRT or RCDT operations that affect tank levels.

Operating with VCT level near the divert setpoint of 63% may cause erratic readings due to diversion of letdown to the HUT (which is NOT accounted for in the calculations). Reducing VCT level to less than 60% before initiating performance will minimize the possibility of errors in the calculations.

To ensure that test results are as accurate as possible, the test should NOT begin until at least 30 minutes following evolutions such as dilution, boration, or rod movement.

Zinc injection, as implemented by DCN 52122, is limited to a maximum of 8 ml per minute (about 0.002 gpm). This amount of inventory increase is NOT detectable within the methodology of this procedure.

1.0 INTRODUCTION

1.1 Purpose This Instruction provides detailed steps to perform a Reactor Coolant System (RCS) water inventory balance.

1.2 Scope 1.2.1 Operability Test to be Performed Operations that could affect RCS water inventory (makeup and sampling) are terminated and the RCS is stabilized. VMth the RCS stable, parameters such as temperature, pressure, and associated tank levels are measured at one hour or greater intervals. When at least two sets of data have been collected, identified and Unidentified leakages are calculated using the rate of change between the data sets.

Then, the calculated leakage rates are compared to values in Technical Specification Limiting Condition for Operation (LCO) 3.4.13 to determine RCS 4

operability.

WBN 68-32 Reacr Unit I Wate Inventory Balance 0014 Page 7 of 32 3M PRECAUTIONS AND LIMITATIONS The final RCS temperature must be within +/- 0.3°F of the initial RCS temperature or the final data is VOID and must be retaken.

The final RCS power level must be within +/- 1.0% of the initial RCS power level or the final data is VOID and must be retaken.

Makeup to the Volume Control Tank (VCT) is isolated and VCT level is expected to decrease during this SI. If VCT level falls to 20% or low VCT level alarm annunciates before final data is recorded, makeup to the VCT will be required and the test will have to be voided and reperformed.

The Reactor Coolant Drain Tank (RCDT) pumps are placed in PULL-TO-LOCK with 1-FCV-68-310, PRT DRAIN, closed. At the same time, RCDT and Pressurizer Relief Tank (PRT) levels are expected to increase. If PRT or RCDT high level alarm annunciates before final data is recorded, pump-down of the PRT or RCDT will be required and the test will have to be voided and reperformed.

Instruments such as PZR pressure and level or any other instruments used by the RCS Inventory Program that are removed from service during the performance of this SI will cause the quality to be bad on the final data sheet.

Any revisions to this SI will require coordination with the Computer Engineering Group to change the SI revision level displayed on the ICS Water Inventory Balance screen.

Any revisions or modifications to this procedure that affect the water inventory balance calculation or that could affect the ICS software will require a Computer Software Service Request (SSR) per SPP-2.6 to make the applicable software changes to the ICS Water Inventory Balance.

If any of the following events occur during performance of Section 6.0 the data is VOID and the test must be restarted after initial conditions are reestablished:

Any instrument or computer data point used to obtain initial data is NOT available for final data.

Emergency boration.

Diversion of letdown to the hold up tanks.

Makeup from any source.

Change in primary side purification demineralizers or filter lineup.

Failure to accumulate data for at least 1 hour1.157407e-5 days <br />2.777778e-4 hours <br />1.653439e-6 weeks <br />3.805e-7 months <br />.

F C XAM MATERIA

WBN AD-M1-NJRM--KEY Reactor Coolant System 1-SI-68-32 Unit I Water Inventory Balance Rev. 0014 Page 8of32 3.0 PRECAUTIONS AND LIMITATIONS (continued)

Restarting the primary water pumps if they were stopped before the initial data was collected.

Sampling the RCS or making chemical additions to the RCS (with the exception of RCS Zinc Injection).

PRT or RCDT operations that affect tank levels.

Operating with VCT level near the divert setpoint of 63% may cause erratic readings due to diversion of letdown to the HUT (which is NOT accounted for in the calculations). Reducing VCT level to less than 60% before initiating performance will minimize the possibility of errors in the calculations.

To ensure that test results are as accurate as possible, the test should NOT begin until at least 30 minutes following evolutions such as dilution, boration, or rod movement.

Zinc injection, as implemented by DON 52122, is limited to a maximum of 8 ml per minute (about 0.002 gpm). This amount of inventory increase is NOT detectable within the methodology of this procedure.

INITIAL CONDITIONS:

TREAT THIS AS A RADIOLOGICAL EMERGENCY DRILL

1. A Drill is being conducted during which Unit I was at 90% RTP when the crew manually initiated a Reactor Trip and Safety Injection due to a SGTR on SG #1 of approximately 100 gpm.

2. An ALERT was declared 15 minutes ago, and EPIP-3, Alert has been implemented.

3. The Shift Technical Advisor NOW reports the following conditions exist on Unit 1:

a. One Safety Valve on SO #1 opened and failed to reclose.

b. The Chemistry Supervisor reports RCS activity is 340 uCilgram dose equivalent 1-131.

c. All Status Trees are GREEN except for FR-H.5, Steam Generator Low Level, which is YELLOW due to level in SG #1 at 50% wide range.

d. Atmospheric conditions indicate the wind is from 90 degrees at 10 mph.

INITIATING CUES:

1. As the SED, you are to evaluate current plant conditions and decide the appropriate actions.

2. Once your decision is made, fill out the appropriate forms to make notifications to appropriate personnel.

3. This JPM contains time critical elements.
