NOTE Leakage rates, for comparison purposes, should always be converted to standard flow rate conditions (flow at 70°F, one standard atmosphere). Since nitrogen gas is supplied by evaporating liquid nitrogen and heating it to approximately 70°F then reducing the pressure to 2.0 psig the conversion is:

14. 7psia + 2.0psig X 460°R + 70° =1.136 14.7psi 460°R + 70°F Where: 14. 7 psia =1 standard atmosphere 2.0 psig =nitrogen supply pressure 460°R = Fahrenheit to Rankine conversion factor 70°F =degrees Fahrenheit of nitrogen, actual and standard For calculation purposes, a day consists of 24-hours. During the days when the time changes to Daylight Savings Time (DST) 23-hours will be Critical Step used. When returning to Central Standard Time (CST) 25-hours will be used. To average the net nitrogen usage (in ft3) for a day, a 24 hour _SAT period is normally used and the results are expressed in standard cubic feet per hour. The net nitrogen leakage is multiplied by a conversion _UNSAT factor 1.136, then divided by the number of hours in the day. The result gives the average nitrogen leakage in standard cubic feet per hour for _N/A that day. When Daylight Savings Time and Central Standard Time changes take place, the appropriate number of hours will be used instead of 24 (hours).

[1] MULTIPLY the net nitrogen leakage from Attachment 6, Section A, (Nitrogen Leakage table) by (1.136/Hours during the day). [2] RECORD the result on the Average Nitrogen Leakage line. Standard: Multiplies Net Nitrogen Leakage of -158.06 OR -158.1ft3 by 1.136 and divides by 24 hours to determine an Average Nitrogen Leakage of -7.48 OR -7.5 SCFH.

1.0 INTRODUCTION

1.1 Purpose This Surveillance Instruction provides the necessary steps to monitor the primary containment nitrogen consumption rate (i.e .. primary containment system leakage) in compliance with the requirements in Technical Specification 3.6.1.1 and TRM 3.6.2, and 3.6.5. 1.2 Scope Primary containment nitrogen consumption is monitored to determine the average daily nitrogen consumption. Corrections are made for Suppression Chamber level changes and Drywell/Suppression Chamber venting that may occur. The average nitrogen leakage is calculated using data gathered during the day of this test. For calculation purposes, a day consists of 24-hours. During the days when the time changes to Daylight Savings Time (DST) 23-hours will be used. When returning to Central Standard Time (CST) 25-hours will be used. 1.3 Frequency This Surveillance Instruction shall be performed each day (24-hour duration except the days converting to Daylight Saving Time and returning to Central Standard Time) and reviewed each shift while the reactor is in the RUN mode (Mode 1) and primary containment is inerted. This procedure is initially started when the conditions are met during Reactor Startup and remains in process until the following Midnight (2400 Hours). This procedure should be initiated at Midnight (0000 Hours) and remain in process for a 24 Hour period (until the following Midnight (2400 Hours)) or when conditions are no longer met during Reactor Shutdown per Tech Specs.

This procedure should be initiated at Midnight (0000 Hours) and remain in process for a 24 Hour period (until the following Midnight (2400 Hours)). B. If it is necessary to begin a new revision of the procedure before the time period is completed, then the appropriate data must be transferred to the new document and the two procedures maintained together. C. For an INDEPENDENT REVIEWER signature, the STA or SRO cannot perform any actions or signoffs in the body of the procedure. This will ensure an adequate review of the procedure. 3.2 Operability and LCO's A. If Nitrogen leakage exceeds 542 SCFH, 1-AOl-64-7, and TECH SPECS must be referred to for further action.

1. If 24-Hour average Nz makeup to the primary containment is > 542 SCFH then Primary Containment must be declared INOP immediately.

(Refer to LCO 3.6.1.1.) B. If the nitrogen consumption demonstrates a trend that will be greater than 542 SCFH for the 24-hour period, notify the Unit Supervisor (US) immediately. 3.3 Equipment A. When a Drywell Control Air Totalizer is INOP, the OWCA System Engineer will use the AUO rounds to determine the average flow to be used for N2 Drywell Control Air Flow. B. When a Drywell Control Air Totalizer is INOP and a break or a leak occurs in the drywell from an air line, the number of times the drywell is vented will rise based on the severity of the leak or break. System Engineering should monitor and address any rise in Venting Requirements to determine if it is caused by a Drywall Control Air Line leak or due to atmospheric conditions. 3.4 Initiation/Isolation/Trips None 3.5 Interlocks None

BFN Primary Containment Nitrogen 1-Sl-4.7 .A.2.A Unit 1 Consumption and Leakage Rev.0012 Page 9of43 3.6 Performance Testing A. Since changes in Suppression Chamber level change the Suppression Chamber free volume, the Torus atmospheric pressure will change, although nitrogen may not have been lost or added.

1. The Suppression Chamber level may change for any number or events such as venting the Orywell/Suppression Chamber, pumping down the Suppression Chamber, MRSVs Leakage or testing Core Spray, RHR, HPCI, or RCIC Systems.

2. The correction for level changes is based on the assumption that the Suppression Chamber level change is relatively small {-1" to -7.25" indicated level) allowing the effect of Suppression Chamber curvature to be neglected. Therefore, the 909.8 cubic feet change in volume per one inch change in Suppression Chamber level is assumed constant.

B. Changes in either the Orywell or Suppression Chamber Air Temperature would cause a change in Containment Pressure under ideal conditions. Due to the continuous Drywell Control Air addition and possible venting during the 24 hour period the changes in containment pressures may not be as expected. Therefore when a change of more than 2 °F in either area occurs a Temperature Correction will be performed for that area's Air Temperature, otherwise zero "O" will be used for the correction factor. C. For Sections 7.5 and 7. 7.1 if one pressure indicator and/or differential indicator is inoperable, then the appropriate column on the Attachment is to be marked NIA, the INOP indicator noted on Attachment 1, and dividing by 2 is to be omitted for that particular term in the equation. D. Attachment 3, Section B should be used to calculate the venting correction factor when any of the following instrumentation is unavailable.

1. Both DRYWELL PRESSURE, 1-Pl-64-135 and 1-Pl-64-136

2. DRYWELL TEMPERATURE, 1-Tl-64-52AB E. Attachment 4, Section B should be used to calculate the venting correction factor when any of the following instrumentation is unavailable.

1. Both DRYWELL PRESSURE, 1-Pl-64-135 and 1-Pl-64-136

2. Both OW/SUPPR CHBR DIFF PRESS, 1-PDl-64-137 and 1-PDl-64-138

3. DRYWELL TEMPERATURE, 1-XR-64-52

4. SU PPR POOL WATER LEVEL, 1-Ll-64-54A and 1-Ll-64-66.

BFN Primary Containment Nitrogen 1-Sl-4.7 .A.2.A Unit 1 Consumption and Leakage Rev.0012 PaQe 10 of 43 3.6 Performance Testing (continued) F. Drywell/Suppression Chamber venting may be required to maintain Drywell pressure within limits during changes in barometric pressure, maintenance on Drywell Delta P Air Compressor, or other similar events. When using the Alternate Venting Correction equation in Attachment 6, the following assumptions are used.

1. The Drywell free volume is 159,000 cubic feet.

2. The Suppression Chamber free volume is 126,200 cubic feet at -1 inches (SUPPR POOL WATER LEVEL, 1-Ll-64-54A, or SUPPR POOL WATER LEVEL, 1-Ll-64-66), and an additional 909.8 cubic feet of free volume for each inch that water level is lowered.

3. The actual venting process is a rapid event so barometric pressure changes can be neglected.

4. The average Drywell temperature change is represented by DRYWELL TEMPERATURE, 1-Tl-64-52AB, and DRYWELL TEMPERATURE/PRESSURE 1-XR-64-50.

5. Orywell and Suppression Chamber nitrogen pressures are low enough to use the ideal gas law as a model, i.e.

vc = 1 -[ PB TA ] p T x vt A B Where: Ve= Venting Correction P6 = Drywall or Suppression Chamber pressure before venting PA= Drywell or Suppression Chamber pressure after venting T6 = Drywell or Suppression Chamber temperature before venting TA= Drywell or Suppression Chamber temperature after venting V1= Total free volume of Drywall or Suppression Chamber

6. The Suppression Chamber water and atmospheric temperatures are in equilibrium.

Drywell/Suppression Chamber Venting Correction Factor are absolute values. (No Negative totals) H. TSB 3.3.3.1 (PAM instrumentation) states that for OW temperature that two wide range drywell atmosphere temperature signals are transmitted from separate temperature sensors and are continuously recorded and displayed on one CR recorder (XR-64-50) and one control room indicator (Tl-64-52AB). Therefore, it's reasonable that either indicator should be adequate for use in the calculation of N2 consumption.

1) Drywell/Suppression Chamber Venting Correction Factor are absolute values. (No Negative totals)

2) TSB 3.3.3.1 (PAM instrumentation) states that for OW temperature that two wide range drywell atmosphere temperature signals are transmitted from separate temperature sensors and are continuously recorded and displayed on one CR recorder (XR-64-50) and one control room indicator (Tl-64-52A8). Therefore, it's reasonable that either indicator should be adequate for use in the calculation of N2 consumption.

Since nitrogen gas is supplied by evaporating liquid nitrogen and heating it to approximately 70°F then reducing the pressure to 2.0 psig the conversion is:

14. 7psia + 2.0psig x 460°R + 70°F = I . 136 14.7psia 460°R + 70°F Where: 14. 7 psia = 1 standard atmosphere 2.0 psig = nitrogen supply pressure 460°R = Fahrenheit to Rankine conversion factor 70°F = degrees Fahrenheit of nitrogen, actual and standard For calculation purposes, a day consist of 24-hours. During the days when the time changes to Daylight Savings Time (OST) 23-hours will be used. When returning to Central Standard Time (CST) 25-hours will be used.

To average the net nitrogen usage (in ft3 >for a day, a 24 hour period is normally used and the result are expressed in standard cubic feet per hour. The net nitrogen leakage is multiplied by a conversion factor 1.136, then divided by the number of hours in the day. The result gives the average nitrogen leakage in standard cubic feet per hour for that day. When Daylight Savings Time and Central Standard Time changes take place, the appropriate number of hours will be used instead of 24 (hours).

1) Alternate Containment Venting Data is performed when 1-FIC-84-20 indication is not available.

2) In this table the BEFORE is prior to establishing flow through the vent valves.

3) The AFTER is when venting is completed, regardless of the number of times for the event. It can also be taken either before or after the DP Air Compressor pumps up the drywell, but do not take data while the DP is running.

4) Use 1-Ll-64-54A unless INOP then use 1-Ll-64-66.

5) Drywell/Suppression Chamber Venting Correction Factor are absolute values. (No Negative totals)

6) It is assumed in 3.6F.6 that the suppression chamber water and atmospheric temperatures are in equilibrium, therefore the use of the average suppression pool water temperature is an acceptable substitute in place of the suppression chamber air temperature.

IF SUPP CHBR TEMP,1-TE-64-528 on SUPPRESSION CHAMBER TEMPERATURE/PRESSURE, 1-XR-64-52 (point 1), is unavailable, THEN Suppression Pool Water Temperature, 1-TR-64-161 (Point 10) can be substituted. [BFNPER607653-002i

• The Condensate makeup valve 2-SHV-078-0532 is danger tagged closed.
• Unit 2 received Fuel Pool Skimmer Surge Tank Level Lo/Lo-Lo (9-4C, W4).
• Compensatory hoses connected to demin water connections are not maintaining Fuel Pool level.
• Unit 2 received Fuel Pool System Abnormal (9-4C, W1) AND Fuel Pool Floor Area Radiation High (9-3A, W1)
• The Fuel Pool liner is leaking and Fuel Pool level is lowering. Unit 2 entered 2-AOl-78-1, Fuel Pool Cleanup System Failure
• Loss of Offsite Power occurred and the C and D Diesel Generators failed to start.
• Unit 2 attempted to restore Fuel Pool level using EECW however, 1-SHV-067-0792 North Header supply to Emergency Fuel Pool Make Up will not open and the South EECW header is depressurized.
• Unit 2 attempted to align RHRSW to inject to the Fuel Pool; however, 1-FCV-23-57, Standby Coolant valve would not open electrically.
• The Fuel Pool leak is progressively getting larger and the Fuel Pool level will be at the top of the fuel bundles within 15 minutes.
