0919 Stopped power increase at 100%, 855 MWe. 2400 The reporting period ended with the unit operating at 100% power, 835 MWe. | 3/13/96 0258 Started power reduction to facilitate the installation of temporary piping from the reactor coolant pump, 2-RC-P-1 A, oil collection tank drain to a low dose area outside of the loop room to provide a means for remotely draining the subject tank, if necessary. | ||
0605 Stopped power reduction at 30%, 220 MWe. | |||
March, 1996 Temporary Modification (Safety Evaluation No. 96-019) | 2315 Started power increase. | ||
Therefore, an unreviewed safety question does not exist. Deviation Report 3-11-96 (Safety Evaluation No. 96-021, Revision 1) Safety Evaluation 96-021 assessed Deviation Report S-95-0448 concerning the existence of a motor bearing oil leak on the Unit 2 "A" Reactor Coolant Pump (RCP). The evaluation concluded that continued RCP operation is acceptable since the estimated leakage amount is small and within the current capacity of the oil collection system tank. In addition, adequate warning systems and procedures exist to alert operators and address low oil level and high bearing temperature conditions. | 3/14/96 0706 Stopped power increase at 96%, 800 MWe, to perform calorimetric calculation. | ||
Therefore, an unreviewed safety question does not exist. Justification for Continued Operation (Safety Evaluation 96-023) | 0854 Started power increase. | ||
The cause of the failure was preliminarily identified as intergranular corrosion in combination with a reduction in pipe wall thickness. | 0919 Stopped power increase at 100%, 855 MWe. | ||
The leaking section of piping was replaced and ultrasonic testing (UT) was performed on the remainder of the affected Unit 2 piping and the corresponding Unit 1 piping. The UT identified the existence of degradation at other locations on the Unit 2 piping. The Unit 1 piping was acceptable. | 3/31/96 2400 The reporting period ended with the unit operating at 100% power, 835 MWe. | ||
tlurry Monthly Operating Report No. 96-03 Page 10 of 20 FACILITY CHANGES THAT DID NOT REQUIRE NRC APPROVAL MONTHNEAR: March, 1996 TM S2-96-002 Temporary Modification 3-06-96 (Safety Evaluation No. 96-019) | |||
Temporary Modification (TM) S2-96-002 interchanged the electrical leads to the Unit 2 high level intake structure rotating screen motor. This modification reversed the direction of screen rotation in order to facilitate the installation of new drive chains. | |||
The high level intake structure remained fully operable during the subject maintenance activity and the ability of the service water system to perform its design function was not affected. Therefore, an unreviewed safety question does not exist. | |||
DR S-96-0448 Deviation Report 3-11-96 (Safety Evaluation No. 96-021, Revision 1) | |||
Safety Evaluation 96-021 assessed Deviation Report S-95-0448 concerning the existence of a motor bearing oil leak on the Unit 2 "A" Reactor Coolant Pump (RCP). | |||
The evaluation concluded that continued RCP operation is acceptable since the estimated leakage amount is small and within the current capacity of the oil collection system tank. | |||
In addition, adequate warning systems and procedures exist to alert operators and address low oil level and high bearing temperature conditions. Therefore, an unreviewed safety question does not exist. | |||
JCO S2-96-001 Justification for Continued Operation 3-11-96 (Safety Evaluation 96-023) | |||
A through wall leak was recently discovered on Unit 2 residual heat removal system pipe 6"-RH-120-152. The cause of the failure was preliminarily identified as intergranular corrosion in combination with a reduction in pipe wall thickness. The leaking section of piping was replaced and ultrasonic testing (UT) was performed on the remainder of the affected Unit 2 piping and the corresponding Unit 1 piping. The UT identified the existence of degradation at other locations on the Unit 2 piping. The Unit 1 piping was acceptable. | |||
Justification For Continued Operation (JCO) 82-96-001 assessed the acceptability of continued Unit 2 operation with the degraded piping. The JCO requires a visual inspection of the affected Unit 2 piping on a monthly basis, until the piping is replaced, to ensure that any additional leakage is identified and that containment integrity is maintained. | Justification For Continued Operation (JCO) 82-96-001 assessed the acceptability of continued Unit 2 operation with the degraded piping. The JCO requires a visual inspection of the affected Unit 2 piping on a monthly basis, until the piping is replaced, to ensure that any additional leakage is identified and that containment integrity is maintained. | ||
An engineering evaluation concluded that the affected piping will maintain its integrity during normal and accident conditions and can be considered fully operable. | An engineering evaluation concluded that the affected piping will maintain its integrity during normal and accident conditions and can be considered fully operable.

-urry Monthly Operating Report No. 96-03 Page 11 of 20 FACILITY CHANGES THAT DID NOT REQUIRE NRC APPROVAL MONTHNEAR: March, 1996 TM S2-96-003 Temporary Modification 3-12-96 (Safety Evaluation No. 96-024) | |||
March, 1996 | Temporary Modification (TM) S2-96-003 installed temporary piping from the Unit 2 "A" reactor coolant pump oil collection tank drain to a low dose area outside of the loop room. | ||
Therefore, an unreviewed safety question does not exist. Design Change Package (Safety Evaluation No. 95-139) | The TM was implemented to provide a means for remotely draining the subject tank, if necessary, to accommodate a small motor bearing oil leak that has reduced the margin between the tank capacity and the total capacity of the RCP motor. | ||
The modification did not affect the CLS or other systems. Therefore, an unreviewed safety question does not exist. Temporary Modification (Safety Evaluation No. 96-025) | The temporary piping is seismically restrained and does not affect the performance of the oil collection system. Any oil drained from the oil collection tank will be removed from the containment. Therefore, an unreviewed safety question does not exist. | ||
Therefore, an unreviewed safety question does not exist. Updated Final Safety Analysis Report Change (Safety Evaluation No. 96-026) | DCP 95-037 Design Change Package 3-13-96 (Safety Evaluation No. 95-139) | ||
The new analysis parameters were equivalent to, or conservative with respect to, those allowed by Technical Specifications limits. The analysis parameters are therefore expected to be conservative with respect to actual plant conditions. | Design Change Package 95-037 installed an electrical jumper to bypass failed Unit 1 consequence limiting safeguards (CLS) relay, 1-CLS-RLY-1 A9, and clear control room annunciator 1-B-4, "CLS Coil Failure." | ||
Thus, continued operation in accordance with the Technical Specifications will not violate the design basis of plant safety systems and equipment. | The subject relay is a spare that currently performs no function. The modification did not affect the CLS or other systems. Therefore, an unreviewed safety question does not exist. | ||
Therefore, an unreviewed safety question does not exist. | TM S2-96-004 Temporary Modification 3-14-96 (Safety Evaluation No. 96-025) | ||
Temporary Modification (TM) S2-96-004 installed an electrical jumper to maintain alarm module circuit continuity during the replacement of the Unit 2 "A" circulating water (CW) pump thrust bearing alarm module. | |||
March, 1996 Design Change Package (Safety Evaluation No. 91-122) - | The module alarm functions do not provide any control or interlock functions for the CW pump motor supply breakers and do not prevent the start or cause the trip of a CW pump. | ||
The modifications provided an alternative method of injecting the proper amount of ammonia into the condensate system to control the pH level. The changes did not affect the operation or ability of equipment important to safety to perform its designed safety function. | The TM did not affect the other Unit 2 "A" CW pump motor temperature thermocouples and alarm functions and did not impose any operational limitations on the subject pump. | ||
Therefore, an unreviewed safety question does not exist. Design Change Package (Safety Evaluation No. 96-030) | Double verification of jumper installation/removal and post-maintenance testing was performed. Therefore, an unreviewed safety question does not exist. | ||
To accommodate the installation of the replacement pump, the diesel engine drive shaft coupling and the inlet/outlet piping for the lube oil cooler were modified. | FS 96-05 Updated Final Safety Analysis Report Change 3-18-96 (Safety Evaluation No. 96-026) | ||
In addition, the nonsafety-related electric motor driver, which was used for maintenance purposes, was not compatible with the replacement pump and, therefore, was removed. The replacement pump is sized to satisfy the flow requirements for the design basis conditions defined in the Updated Final Safety Analysis Report. The modifications were structurally and seismically evaluated and determined to be acceptable. | UFSAR Change 96-05 revised Section 14.2.8, "Excessive Load Increase Incident," to reflect the results of a new analysis that was recently performed based on the Unit 1 and Unit 2 uprated core power (2546 MWt) conditions and the new design limits for the moderator temperature and Doppler temperature coefficients. | ||
The operability, availability, and performance characteristics of the subject pump were not affected by the changes. Therefore, an unreviewed safety question does not exist. Updated Final Safety Analysis Report Change (Safety Evaluation 96-034) | The new analysis parameters were equivalent to, or conservative with respect to, those allowed by Technical Specifications limits. The analysis parameters are therefore expected to be conservative with respect to actual plant conditions. Thus, continued operation in accordance with the Technical Specifications will not violate the design basis of plant safety systems and equipment. Therefore, an unreviewed safety question does not exist. | ||
The changes did not represent significant deviations from the design basis of the fuel handling system and did not reduce the Technical Specifications margin of safety. The changes also did not affect any of the assumptions made in any fuel handling or other design basis accident analyses. | |||
Therefore, an unreviewed safety question does not exist. | -urry Monthly Operating Report No. 96-03 Page 12 of 20 FACILITY CHANGES THAT DID NOT REQUIRE NRC APPROVAL MONTHNEAR: March, 1996 DCP 91-004 Design Change Package 3-27-96 (Safety Evaluation No. 91-122) | ||
Design Change Package 91-004 eliminated the dilute ammonia tanks, installed new ammonia injection pumps, and cross-connected the Unit 1 and Unit 2 ammonia injection pump suction and discharge piping to provide greater operational flexibility. | |||
The modifications provided an alternative method of injecting the proper amount of ammonia into the condensate system to control the pH level. The changes did not affect the operation or ability of equipment important to safety to perform its designed safety function. Therefore, an unreviewed safety question does not exist. | |||
March, 1996 | DCP 96-009 Design Change Package 3-28-96 (Safety Evaluation No. 96-030) | ||
Appropriate administrative controls are provided in the procedures to ensure that the subject valves are closed within 60 seconds of the initiation of a safety injection. | Design Change Package 96-009 replaced emergency service water pump 1-SW-P-1A. To accommodate the installation of the replacement pump, the diesel engine drive shaft coupling and the inlet/outlet piping for the lube oil cooler were modified. In addition, the nonsafety-related electric motor driver, which was used for maintenance purposes, was not compatible with the replacement pump and, therefore, was removed. | ||
Closure of the valves within this time limit ensures that sufficient refueling water storage tank inventory is maintained for accident mitigation. | The replacement pump is sized to satisfy the flow requirements for the design basis conditions defined in the Updated Final Safety Analysis Report. The modifications were structurally and seismically evaluated and determined to be acceptable. The operability, availability, and performance characteristics of the subject pump were not affected by the changes. Therefore, an unreviewed safety question does not exist. | ||
Therefore, an unreviewed safety question does not exist. Operating Procedure | FS 96-12 Updated Final Safety Analysis Report Change 3-29-96 (Safety Evaluation 96-034) | ||
The procedure allows the mechanical jumper to be installed while the unit is at cold/refueling shutdown when the SI System is not required. | Updated Final Safety Analysis Report Change 96-12 revised various sections that address fuel handling to accurately reflect current station practices. | ||
The jumper will be rated for the pressure of the associated piping flow path, inspected for leakage after it is placed in service, and removed before the unit leaves cold shutdown. | The changes did not represent significant deviations from the design basis of the fuel handling system and did not reduce the Technical Specifications margin of safety. The changes also did not affect any of the assumptions made in any fuel handling or other design basis accident analyses. Therefore, an unreviewed safety question does not exist. | ||

Temporary Modification (TM) S2-96-002 interchanged the electrical leads to the Unit 2 high level intake structure rotating screen motor. This modification reversed the direction of screen rotation in order to facilitate the installation of new drive chains.
The high level intake structure remained fully operable during the subject maintenance activity and the ability of the service water system to perform its design function was not affected. Therefore, an unreviewed safety question does not exist.
DR S-96-0448 Deviation Report 3-11-96 (Safety Evaluation No.96-021, Revision 1)
Safety Evaluation 96-021 assessed Deviation Report S-95-0448 concerning the existence of a motor bearing oil leak on the Unit 2 "A" Reactor Coolant Pump (RCP).
The evaluation concluded that continued RCP operation is acceptable since the estimated leakage amount is small and within the current capacity of the oil collection system tank.
In addition, adequate warning systems and procedures exist to alert operators and address low oil level and high bearing temperature conditions. Therefore, an unreviewed safety question does not exist.
JCO S2-96-001 Justification for Continued Operation 3-11-96 (Safety Evaluation 96-023)
A through wall leak was recently discovered on Unit 2 residual heat removal system pipe 6"-RH-120-152. The cause of the failure was preliminarily identified as intergranular corrosion in combination with a reduction in pipe wall thickness. The leaking section of piping was replaced and ultrasonic testing (UT) was performed on the remainder of the affected Unit 2 piping and the corresponding Unit 1 piping. The UT identified the existence of degradation at other locations on the Unit 2 piping. The Unit 1 piping was acceptable.
Justification For Continued Operation (JCO) 82-96-001 assessed the acceptability of continued Unit 2 operation with the degraded piping. The JCO requires a visual inspection of the affected Unit 2 piping on a monthly basis, until the piping is replaced, to ensure that any additional leakage is identified and that containment integrity is maintained.
An engineering evaluation concluded that the affected piping will maintain its integrity during normal and accident conditions and can be considered fully operable. Therefore, an unreviewed safety question does not exist.
-urry Monthly Operating Report No. 96-03 Page 11 of 20 FACILITY CHANGES THAT DID NOT REQUIRE NRC APPROVAL MONTHNEAR: March, 1996 TM S2-96-003 Temporary Modification 3-12-96 (Safety Evaluation No.96-024)
Temporary Modification (TM) S2-96-003 installed temporary piping from the Unit 2 "A" reactor coolant pump oil collection tank drain to a low dose area outside of the loop room.
The TM was implemented to provide a means for remotely draining the subject tank, if necessary, to accommodate a small motor bearing oil leak that has reduced the margin between the tank capacity and the total capacity of the RCP motor.
The temporary piping is seismically restrained and does not affect the performance of the oil collection system. Any oil drained from the oil collection tank will be removed from the containment. Therefore, an unreviewed safety question does not exist.
DCP 95-037 Design Change Package 3-13-96 (Safety Evaluation No.95-139)
Design Change Package 95-037 installed an electrical jumper to bypass failed Unit 1 consequence limiting safeguards (CLS) relay, 1-CLS-RLY-1 A9, and clear control room annunciator 1-B-4, "CLS Coil Failure."
The subject relay is a spare that currently performs no function. The modification did not affect the CLS or other systems. Therefore, an unreviewed safety question does not exist.
TM S2-96-004 Temporary Modification 3-14-96 (Safety Evaluation No.96-025)
Temporary Modification (TM) S2-96-004 installed an electrical jumper to maintain alarm module circuit continuity during the replacement of the Unit 2 "A" circulating water (CW) pump thrust bearing alarm module.
The module alarm functions do not provide any control or interlock functions for the CW pump motor supply breakers and do not prevent the start or cause the trip of a CW pump.
The TM did not affect the other Unit 2 "A" CW pump motor temperature thermocouples and alarm functions and did not impose any operational limitations on the subject pump.
Double verification of jumper installation/removal and post-maintenance testing was performed. Therefore, an unreviewed safety question does not exist.
FS 96-05 Updated Final Safety Analysis Report Change 3-18-96 (Safety Evaluation No.96-026)
UFSAR Change 96-05 revised Section 14.2.8, "Excessive Load Increase Incident," to reflect the results of a new analysis that was recently performed based on the Unit 1 and Unit 2 uprated core power (2546 MWt) conditions and the new design limits for the moderator temperature and Doppler temperature coefficients.
The new analysis parameters were equivalent to, or conservative with respect to, those allowed by Technical Specifications limits. The analysis parameters are therefore expected to be conservative with respect to actual plant conditions. Thus, continued operation in accordance with the Technical Specifications will not violate the design basis of plant safety systems and equipment. Therefore, an unreviewed safety question does not exist.
-urry Monthly Operating Report No. 96-03 Page 12 of 20 FACILITY CHANGES THAT DID NOT REQUIRE NRC APPROVAL MONTHNEAR: March, 1996 DCP 91-004 Design Change Package 3-27-96 (Safety Evaluation No.91-122)
Design Change Package 91-004 eliminated the dilute ammonia tanks, installed new ammonia injection pumps, and cross-connected the Unit 1 and Unit 2 ammonia injection pump suction and discharge piping to provide greater operational flexibility.
The modifications provided an alternative method of injecting the proper amount of ammonia into the condensate system to control the pH level. The changes did not affect the operation or ability of equipment important to safety to perform its designed safety function. Therefore, an unreviewed safety question does not exist.
DCP 96-009 Design Change Package 3-28-96 (Safety Evaluation No.96-030)
Design Change Package 96-009 replaced emergency service water pump 1-SW-P-1A. To accommodate the installation of the replacement pump, the diesel engine drive shaft coupling and the inlet/outlet piping for the lube oil cooler were modified. In addition, the nonsafety-related electric motor driver, which was used for maintenance purposes, was not compatible with the replacement pump and, therefore, was removed.
The replacement pump is sized to satisfy the flow requirements for the design basis conditions defined in the Updated Final Safety Analysis Report. The modifications were structurally and seismically evaluated and determined to be acceptable. The operability, availability, and performance characteristics of the subject pump were not affected by the changes. Therefore, an unreviewed safety question does not exist.
FS 96-12 Updated Final Safety Analysis Report Change 3-29-96 (Safety Evaluation 96-034)
Updated Final Safety Analysis Report Change 96-12 revised various sections that address fuel handling to accurately reflect current station practices.
The changes did not represent significant deviations from the design basis of the fuel handling system and did not reduce the Technical Specifications margin of safety. The changes also did not affect any of the assumptions made in any fuel handling or other design basis accident analyses. Therefore, an unreviewed safety question does not exist.
~urry Monthly Operating Report No. 96-03 Page 13 of 20 PROCEDURE OR METHOD OF OPERATION CHANGES THAT DID NOT REQUIRE NRC APPROVAL MONTHNEAR: March, 1996 1[2]-0P-Sl-002 Operating Procedures 3-01-96 (Safety Evaluation No.96-018)
Operating Procedures 1[2]-0P-Sl-002, "Safety Injection Accumulators", were revised to provide instructions for administratively controlling safety injection system valves 1[2]-
81-26 while performing the subject procedures.
Appropriate administrative controls are provided in the procedures to ensure that the subject valves are closed within 60 seconds of the initiation of a safety injection. Closure of the valves within this time limit ensures that sufficient refueling water storage tank inventory is maintained for accident mitigation. Therefore, an unreviewed safety question does not exist.
2-0P-Sl-002 Operating Procedure 3-07-96 (Safety Evaluation No.96-020)
Operating Procedure 2-0P-Sl-002, "Safety Injection Accumulators", was revised to provide instructions for installing a temporary mechanical jumper to permit the Unit 2 refueling water storage tank recirculation pumps to be used to fill the Safety Injection (SI)
System accumulators.
The procedure allows the mechanical jumper to be installed while the unit is at cold/refueling shutdown when the SI System is not required. The jumper will be rated for the pressure of the associated piping flow path, inspected for leakage after it is placed in service, and removed before the unit leaves cold shutdown. Therefore, an unreviewed safety question does not exist.
1[2]-0P-Sl-004 Operating Procedures 3-07-96 (Safety Evaluation No. 96-020A)
Operating Procedures 1[2]-0P-Sl-004, "Filling Safety Injection Accumulators Using a Temporary Hydro Pump," were developed to provide instructions for administratively controlling safety injection system valves 1 [2]-Sl-26 while performing the subject procedures. The revision also incorporated instructions for installing temporary modifications to facilitate the use of a temporary hydro pump in the event the normal pump is not operational.
Appropriate administrative controls are provided in the procedures to ensure that the subject valves are closed within 60 seconds of the initiation of a safety injection. Closure of the valves within this time limit ensures that sufficient refueling water storage tank inventory is maintained for accident mitigation. Therefore, an unreviewed safety question does not exist.

Electrical Corrective Maintenance Procedure O-ECM-1806-01, "Protective Relay and Associated Control Circuit Replacement," was temporarily changed to provide instructions for placing the recirculation mode transfer (RMT) system switch for train "B" in the refueling position to facilitate the replacement of electrical relay 1-CS-R-100A2.
While switched to the refueling position, RMT system train "B" will not function and the appropriate Technical Specifications Limiting Condition for Operation will be entered. The redundant train "A" will not be affected and will function as designed. Therefore, an unreviewed safety question does not exist.
