e .Surry Monthly Operating Report No. 96-09 Page 11 of 20 FACILITY CHANGES THAT DID NOT REQUIRE NRC APPROVAL MONTH/YEAR: September, 1996 Appendix R Report Technical Report 9-5-96 (Safety Evaluation No.96-115)

The tracking of combustible loading for areas of the station is being eliminated for fire areas that do not have explicit statements concerning combustible loading discussed in NRG Safety Evaluation Reports (SERs). The current combustible loading will be retained in the Appendix R Report as a reference for these fire areas but will not be updated.

Significant changes, such as new types of combustibles will be maintained in general by the fire hazards analysis which is maintained in the Evaluation of Specific Plant Areas section of the UFSAR (9.10.4).

This change will not affect the ability to safely shutdown in the event of a fire. All barriers required by Appendix R are three hour rated or evaluated and will remain in place. There will be no change to the fire protection systems or the fire brigade. Transient controls on combustibles remain in place. Therefore, an unreviewed safety question does not exist.

FS 96-29 Updated Final Safety Analysis Report Change 9-5-96 (Safety Evaluation 96-114)

This change updates the fire protection portions of the UFSAR to correct inconsistencies and out dated material. This change does not adversely affect the ability of the plant to safely shutdown in the event of a fire. All fire protection equipment currently in service will remain in service.

This change does not affect the margins of safety, since all fire protection systems will remain in place. The Operating License and the Technical Specifications will not be affected because the design descriptions that are being revised for clarity are not in the Operating License or the Technical Specifications. Therefore, an unreviewed safety question does not exist.

DCP 95-011 Design Change Package 9-09-96 (Safety Evaluation 95-174)

Design Change Package (DCP)95-011 replaced the existing 3,000 horsepower Main Feedwater Pump motors with new 3,500 horsepower motors. There is no impact on the margin of safety as the motors themselves are not directly responsible for any safety related function and the motor size is not mentioned in the Technical Specifications. No new failure modes exist, since this is a replacement of existing equipment with equal or better than existing equipment. Therefore there are no unreviewed safety questions.

e ~urry Monthly Operating Report No. 96-09 Page 12 of 20 FACILITY CHANGES THAT DID NOT REQUIRE NRC APPROVAL MONTH/YEAR: September, 1996 TM 82-96-17 Temporary Modification 9-16-96 TM 82-96-24 (Safety Evaluation No.94-088 Rev. 1)

These TMs connect a chart recorder to allow for the continuous monitoring of the Unit 2 Pressurizer Safety Valve acoustic monitor. This will allow for more precise and continuous monitoring.

The pressurizer utilizes redundant indications of safety valve position. The primary

  • indication is an acoustic monitoring channel and the backup is a downstream high temperature channel. This activity will provide for continuous monitoring of the primary indication through the use of a strip chart recorder. The installed acoustic monitoring and alarm indication will be unaffected by this TM. Therefore there are no unreviewed safety questions.

TM 82-96-19 Temporary Modification 9-16-96 (Safety Evaluation No.96-095 Rev 1)

This temporary modification routes the Unit 2 Pressurizer Relief Tank vapor space through the sample line to the Gas Purge Line in the Sample Sink to provide a continuous vent. The Gas Purge Line is already connected to the Primary Drains Tank. The continuous vent will then be processed through the Overhead Gas System to the Waste Gas Decay Tanks (WGDT).

Overall radioactive gas releases will be lower from this processing method because the radioactive gaseous waste will now decay in the WGDT instead of being routinely released. This process involves an improvement in the processing of gaseous waste and properly utilizes the existing system for processing gas. Therefore, an unreviewed safety question does not exist.

FS 95-18 Updated Final Safety Analysis Report Change 9-19-96 VPAP-0809 Administrative Procedure (Safety Evaluation 96-066 Rev. 1)

Updated Final Safety Analysis Report Change 95-18 revised Section 98.3, "Control of Heavy Loads," to summarize Virginia Power's commitments related to NUREG-0612.

Administrative procedure VPAP-0809, "NUREG-0612 Heavy Load Program," was also revised to be consistent with the UFSAR.

The subject changes reflect Virginia Power's commitment to comply with the guidelines of NUREG-0612 which provides overall defense-in-depth at preventing load handling accidents. Therefore, an unreviewed safety question does not exist.

e ~urry Monthly Operating Report No. 96-09 Page 13 of 20 FACILITY CHANGES THAT DIDNOT REQUIRE NRC APPROVAL MONTH/YEAR: September, 1996 SE 96-121 Safety Evaluation 9-23-96 (Safety Evaluation No. 96-121}

This safety evaluation was prepared to confirm that the heavy load drops evaluated in the UFSAR bound all of the potential heavy load drops associated with the handling of any of the casks used or planned for use to store spent fuel at Surry.

The probability of occurrence of a heavy load drop during spent fuel cask handling does not depend on the specific cask design used because the handling equipment and methods for handling casks and cask lids remains as described in the UFSAR and ISFSI SAR. Since the consequences of dropping a cask lid or one of the five cask designs is bounded by the cask drop evaluation documented in appendix 98.1 of the UFSAR, the margin of safety will not be decreased. Therefore, an unreviewed safety question does not exist.

TM 82-96-017 Temporary Modifications 9-24-96 TM 82-96-24 (Safety Evaluation No.96-088 Rev 2)

TM 82-96-27 These Temporary Modifications installed a strip chart recorder to provide more precise and continuous monitoring of the Unit 2 Pressurizer Safety Valve acoustic monitors.

The TM does not affect the acoustic monitoring system and alarm indication. The TM does not impact any automatic protection or control functions. Therefore, an unreviewed safety question does not exist.

TM 82-96-27 Temporary Modification 9-24-96 (Safety Evaluation No.96-095 Rev 2)

Temporary modification 82-96-19 routes the Unit 2 Pressurizer Relief Tank vapor space through the sample line and to the Gas Purge Line in the Sample Sink. The Gas Purge Line is already connected to the Primary Drains Tank. The continuous vent will then be processed through the Overhead Gas System to the Waste Gas Decay Tanks (WGDT).

Temporary modification 82-96-27 requires a seismic interaction walkdown be performed by Engineering.

Overall radioactive gas releases will be lower from this processing method because the radioactive gaseous waste will now be decayed in the WGDT instead of being routinely released. This process involves an improvement in the processing of gaseous waste and properly utilizes the existing system for processing gas. Therefore, an unreviewed safety question does not exist.

~urry Monthly Operating Report No. 96-09 Page 14 of 20 FACILITY CHANGES THAT DID NOT REQUIRE NRC APPROVAL MONTH/VEAR: September, 1996 DR S-96-1445 Deviation Report 9-26-96 (Safety Evaluation No.96-123)

The 'A' Main Control Room (MCR) Chiller is currently only capable of being powered via its alternate power supply (2J) and therefore only two MCR Chillers are capable of being powered by two emergency buses. UFSAR Section 9.13.3.6 indicates that three MCR Chillers have this capability. However, this condition does not affect the operability of the MCR Chiller System but only limits the flexibility of equipment alignment.

This condition does not increase the consequences of any accident described in the Safety Analysis or create another type of accident. The 'A' MCR Chiller remains operable, capable of providing its intended function, on its alternate power supply.

Compliance with TS 3.23 is also maintained with this condition. The inoperability of the

'A' MCR Chiller normal power supply is not an unanalyzed condition. Therefore, an unreviewed safety question does not exist.

SE 96-124 Safety Evaluation 9-26-96 (Safety Evaluation No.96-124)

This Safety Evaluation evaluates the 'A' Waste Gas Diaphragm Compressor being out of service for greater than 30 days. The purpose of the compressor is to transfer waste gas from the surge drum to either of the waste gas decay tanks. The redundant 'B' Waste Gas Diaphragm Compressor remains available maintaining the operability of the gaseous waste system.

The unavailability of the 'A' Waste Gas Diaphragm Compressor does not cause or increase the consequences of any accident in the Safety Analysis Report. The compressors are not assumed operable in any analyzed accident. The 'B' Waste Gas Diaphragm Compressor remains operable and capable of providing the intended function of the compressor to transfer waste gas from the surge drum to the waste gas decay tanks. Therefore, an unreviewed safety question does not exist.

TM S1-96-017 Temporary Modification 9-26-96 (Safety Evaluation No.96-125)

This Temporary Modification is used to replace test switch 1-SI-CS-FC-494-TA in the Unit 1 train 'A' of the Safety Injection (SI) system. All work performed will be in the train 'A' portion of the SI system only, train 'B" will remain unaffected and will function as designed at all times. With the jumper installed, train 'A' of the SI system will provide all of it's manual and automatic functions.

The test switch replacement is a like for like replacement with no change to the design of the system or any station isolation. There is no change to the station design. During the time of switch replacement both trains of SI will function as designed. Therefore, an unreviewed safety question does not exist.

~urry Monthly Operating Report No. 96-09 Page 15 of 20 FACILITY CHANGES THAT DID NOT REQUIRE NRC APPROVAL MONTH/YEAR: September, 1996 FS 96-37 Updated Final Safety Analysis Report Change 9-26-96 (Safety Evaluation 96-126)

This UFSAR change revises chapter 17 of the UFSAR to reflect the current organization, including a reference section, clarify what procedures govern non-conformance's found at a vendor's facility and include editorial changes.

These changes are administrative in nature and do not reduce the effectiveness of the QA Program or reduce the commitments in the NRC approved QA Program. There are no changes to any component, system or structure in the plant, or to any method of operations as a result of these changes. Therefore, an unreviewed safety question does not exist.

e e,,urry Monthly Operating Report No. 96-09 Page 16 of 20 PROCEDURE OR METHOD OF OPERATION CHANGES THAT DID NOT REQUIRE NRC APPROVAL MONTH/YEAR: September, 1996 TMOP-3039 Temporary Maintenance Operating Procedure 9-19-96 (Safety Evaluation No.96-120)

Temporary Maintenance Operating Procedure O-TMOP-3039, "Unblocking Ventilation Vent RM Nozzle," was developed to provide instructions for installing a purge supply to the down stream side of the ventilation vent isokinetic nozzle at the input of the ventilation vent radiation monitor, 1-RM-VG-109/110. This modification will enable the ventilation vent multi-ported isokinetic nozzle to be flushed with instrument air to remove a clog that prevents the radiation monitors from drawing a sample from the ventilation vent.

This modification was removed immediately following the purging operation and did not negatively impact any plant equipment or reduce the Technical Specifications margin of safety. Therefore, an unreviewed safety question does not exist.

2-0P-CH-007 Operating Procedures 9-24-96 (Safety Evaluation No.96-122)

The Primary Grade (PG) water flow path to the blender is inoperable. An alternate method of boration and dilution make-up to the VCT is required to support continued operation until the PG flowpath is repaired. The alternate method will align local manual valves to bypass the blender while maintaining flow indication on the Control Room Strip Chart and Flow Integrators.

Administrative control of the flowpaths will be maintained when they are in use. Use of these alternate flowpaths is procedurally controlled. Administrative controls are established to prevent inadvertent dilution. Therefore, an unreviewed safety question does not exist.
