March 1993 SE 93-031 EWR 91-133 SE 93-038 EWR 90-178 Safety Evaluation 02-23-93 Safety Evaluation 93-031 was performed to evaluate the 1993 Unit 2 refueling outage schedule.
The evaluation concluded that the refueling outage schedule is acceptable based on a review of the planning, procedures, policies, shutdown risk, and monitoring management that are performed for the outage. Therefore, an unreviewed safety question does not exist. Engineering Work Request (Safety Evaluation No.91-174) 03-03-93 Engineering Work Request 91-133 removed the internals from Unit 2
- condensate polishing (CP) system valve 2-CP-PCV-221 to allow air flow from air compressor 2-CP-C-1 to the CP air system. This modification does not affect any safety-related equipment or design basis accident analyses.
Therefore, an unreviewed safety question does not exist. Safety Evaluation 03-04-93 Safety Evaluation 93-038 was performed to assess the procedural requirements for the use of ladders, scaffolds, and manlifts provided in administrative procedure VPAP-1903, "Ladders, Scaffolds, and Man lifts." The evaluation also considered the causes and effects of potential ladder and scaffolding failures on plant personnel, systems and components.
It was concluded that temporary scaffolding erected in accordance with VPAP-1903 should not fail while in use, including during a design basis earthquake.
The procedure also provides requirements for the review and control of scaffolding erected in the vicinity of safe shutdown equipment to further minimize the potential risk associated with an earthquake.
Therefore, an unreviewed safety question does not exist. Engineering Work Request 03-05-93 Engineering Work Request 90-178 installed backflow preventers in the floor drains in each of the Unit 1 and 2 charging pump cubicles to prevent potential flooding of the areas through the floor drain system. This modification affected only the floor drains which are not addressed by the Technical Specifications or the Safety Analysis Report. The change will help to assure charging pump operability in the event of internal flooding.
Therefore, an unreviewed safety question does not exist.
SE 93-041 TSR 93-041 TSR 93-008 e Surry Monthly Operating Report No. 93-03 Page 11 of 26 FACILITY CHANGES THAT DID NOT REQUIRE NRC APPROVAL MONTH/YEAR:
March 1993 Safety Evaluation 03-05-93 Safety Evaluation 93-041 was performed to evaluate the use of related Unit 2 charging system flow transmitter 2-CH-FT-2160 to support operation of the alternate charging header during the 1993 Unit 2 refueling outage. The evaluation concluded that it is acceptable to use a nonsafety-related transmitter while the Unit is at cold shutdown (CSD). The transmitter is seismically installed and is capable of withstanding charging pump discharge pressure.
A failure of the subject transmitter while the Unit is at CSD is not applicable to any of the design basis accidents described in the UFSAR. The transmitter will be replaced or removed from service prior to the Unit leaving CSD. Therefore, an unreviewed safety question does not exist. Temporary Shielding Request (Safety Evaluation 93-040) 03-05-93 Temporary Shielding Request 93-041 installed temporary lead shielding on Unit 2 safety injection and containment spray (CS) system piping to reduce the radiation dose received by personnel while performing work in the Unit 2 CS Pumphouse.
Installation of the shielding while the subject lines remain operable was determined to be acceptable through the performance of seismic piping analyses, provided the pressure and temperature do not exceed 350 psi and 450° F. The shielding will not adversely affect the design functions of the affected systems and will be removed prior to exceeding the specified operating conditions.
Therefore, an unreviewed safety question does not exist. Temporary Shielding Request (Safety Evaluation 93-042) 03-08-98 Temporary Shielding Request 93-008 installed temporary lead shielding on aerated drains and reactor cavity purification system piping in the Unit 2 containment basement to reduce the radiation dose received by personnel while performing work in the area. Installation of the shielding while the subject lines remain operable was determined to be acceptable through the performance of seismic piping analyses.
The shielding will not adversely affect the design functions of the affected systems and will be removed prior to the Unit leaving cold shutdown.
Therefore, an unreviewed safety question does not exist.
TSR 93-018 SE 93-044 e Surry Monthly Operating Report No. 93-03 Page 12of 26 FACILITY CHANGES THAT DID NOT REQUIRE NRC APPROVAL MONTH/YEAR:
March 1993 Temporary Shleldlng Request (Safety Evaluation 93-043) 03-08-93 Temporary Shielding Request 93-018 installed temporary lead shielding to the elbows of three safety injection (SI) system accumulator discharge lines in the Unit 2 containment to reduce the radiation dose received by personnel while performing work in the area. Installation of the shielding while the subject lines remain operable was determined to be acceptable through the performance of seismic and deadweight piping analyses.
The shielding will be removed prior to Unit start-up.
Therefore, an unreviewed safety question does not exist. Safety Evaluation 03-09-93 Safety Evaluation 93-044 was performed to evaluate the Unit 2 Cycle 12 reload core, including the use of fresh fuel assemblies that incorporate new anti-snag features in the fuel assembly lnconel grid. Parameters affected by the reload were calculated and compared to the existing safety analysis assumptions.
These parameters were shown to be either 1) explicitly bounded, or 2) accommodated by existing safety analysis margins and/or conservatism.
Operation of the reload core in accordance with the Technical Specifications will not violate the design basis of plant safety equipment.
Thus, the probabilities and consequences of analyzed accidents and equipment malfunctions are not changed by the reload. Therefore, an unreviewed safety question does not exist. TM S2-93-02 Temporary Modification (Safety Evaluation No.93-045) 03-10-93 Temporary Modification (TM) S2-93-02 installed four temporary telephone lines into the Unit 2 Containment using spare conductors in electrical penetration 9C. This TM provides communications capability between personnel inside and those outside the containment during the 1993 Unit 2 refueling outage. The modification will not affect the ability of the electrical penetration to perform its design function or that of systems and components supplied by the penetration.
The TM will be removed prior to the Unit exceeding 200 °F. Therefore, an unreviewed safety question does not exist.

March 1993 Temporary Shleldlng Request (Safety Evaluation 93-047) 03-10-93 Temporary Shielding Requests93-029, 93-030, and 93-031 installed temporary lead shielding on the Unit 2 reactor coolant loop piping and valves (including the loop stop valve by-pass line and valve) to reduce the radiation dose received by personnel while removing the resistance temperature device by-pass lines and performing other work in the area. Installation of the shielding while the subject lines remain operable was determined to be acceptable through the performance of seismic piping analyses, provided the pressure and temperature do not exceed 385 psi and 400° F. The shielding will not adversely affect the design functions of the affected system and will be removed prior to exceeding the specified operating conditions.
Therefore, an unreviewed safety question does not exist. Temporary Shielding Request (Safety Evaluation 93-049) 03-12-93 Temporary Shielding Requests93-011, 93-012, and 93-043 installed temporary lead shielding on Unit 2 residual heat removal (RHR) system piping in the vicinity of the RHR pumps to reduce the radiation dose received by personnel while performing work in the area. Installation of the shielding (in accordance with TSR 93-011) while the subject piping remains operable was determined to be acceptable through the performance of a seismic piping analysis.
Installation of additional shielding (in accordance with TSRs93-012 and 93-043) while the RHR system is not in service was determined to be acceptable through the performance of a deadweight analysis.
The additional shielding will be removed prior to returning the RHR system to service. The remaining shielding will be removed prior to leaving cold shutdown.
Therefore, an unreviewed safety question does not exist. TM S2-93-03 Temporary Modification (Safety Evaluation No.93-051) 03-17-93 Temporary Modification (TM) S2-93-03 installed an electrical jumper around the seal-in contacts for Unit 2 safety injection (SI) system valves 2-SI-MOV-2869A and 2-SI-MOV-28698 to allow the valves to be throttled in order to control reactor coolant system flow from the volume control tank through the idle charging pumps. This change maintains the full operating capability of the subject valves and will not impact the operation of the residual heat removal system. The TM will be in place only when the Unit is at less than 350°F and 450 psig to ensure the SI system is fully operable when required by Technical Specifications.
Therefore, an unreviewed safety question does not exist.

March 1993 DCP 91-41-3 DCP 90-20-02 TSl-016 Design Change Package (Safety Evaluation No.92-020) 03-18-93 Design Change Package (DCP) 91-41-3 installed dedicated steam generator pressure recorders (2 per Unit) to satisfy the requirements for Category I, Type A variables, defined in Regulatory Guide 1.97. This modification provides control room operators with additional information to use during the performance of emergency operating procedures when determining the existence of a failed steam generator and/or tube rupture. The installation will not adversely affect any related systems or components.
Therefore, an unreviewed safety question does not exist. Design Change Package 03-19-93 * (Safety Evaluation No.91-011) Design Change Package (DCP) 90-20-02 added four Unit 2 reactor water storage tank (RWST) level channel trip annunciators to allow control room monitoring of RWST level channel tripping.
Corresponding test points were also installed to provide local test capabilities of the process equipment in the emergency switchgear relay room. This nonsafety-related modification was implemented to comply with the requirements of IEEE 279-1971, Section 4.19. No plant performance characteristics or parameters were altered by this modification.
Therefore, an unreviewed safety question does not exist. Technical Specification Interpretation (Safety Evaluation No.93-055) 03-19-93 Technical Specification Interpretation TSl-016 was developed to describe the actions that need to be taken if the manipulator crane area or airborne radiation monitors become inoperable prior to or during refueling operations (Re: Technical Specifications 3.1 O.A.2, 3.1 O.A.4). The TSl-directed actions secure the containment ventilation purge system when the automatic isolation functions are not operable.
This action places the system in its designed "safe" condition and serves the purpose of the automatic isolation design functions.
This is an accident mitigation action that reduces the potential consequences of a fuel handling accident in the containment.
It does not affect the initiating factors of a fuel handling accident in the containment or any other type of accident.
The TSl-directed actions are consistent with Standard Technical Specifications for Westinghouse Pressurized Water Reactors, NUREG-0452, Revision 4, Section 3.9.9. Therefore, an unreviewed safety question does not exist. Furthermore, this TSI has been discussed with and concurred with by the NRC (Surry's Senior Resident Inspector and NRR Project Manager).

Temporary Shielding Request (Safety Evaluation 93-061) 03-26-93 Temporary Shielding Request 93-028 installed temporary lead shielding on the Unit 2 reactor coolant (RC) and safety injection system piping to reduce the radiation dose received by personnel while performing work in the Unit 2 C Loop Room on safety injection system valves 2-Sl-85 and 2-Sl-243.
Installation of the shielding while the subject lines remain operable was determined to be acceptable through the performance of seismic and deadweight piping analyses.
The shielding will not adversely affect the design functions of the affected systems and will be removed prior to pressurizing the RC system or exceeding 140°F. Therefore, an unreviewed safety question does not exist. Administrative Control (Safety Evaluation No.93-031 A) 03-29-93 Administrative control of Unit 1 auxiliary feedwater (AFW) system valve 1-FW-MOV-1608 will be implemented to ensure AFW cross-tie capability from Unit 2 to Unit 1 is maintained during the period in which Unit 1 AFW system valve 1-FW-MOV-160A is tagged out as part of a 480V 2J bus outage. Unit 1 will be at power and Unit 2 will be at refueling shutdc:,wn (with no fuel in the vessel) during this condition.
Administrative control of the subject valve will not disable an automatic function (the valve is manipulated through remote manual control) and enables the cross-tie to be established within the time period assumed by the accident analyses.
Therefore, an unreviewed safety question does not exist.

March 1993 Temporary Operating Procedure (Safety Evaluation No.93-052) 03-17-93 Temporary Operating Procedure 2-TOP-4028, "Lineup #2 POTT to Pump to #2 VCT," was developed to provide instructions for establishing a valve lineup that allows the Unit 2 primary drains transfer tank (POTT) to be pumped directly to the volume control tank (VCT). This lineup will recycle loop stop valve leakage to the VCT to conserve reactor coolant system (RCS) inventory and boron while the RCS loops are isolated.
This procedure will be performed while the Unit is at cold shutdown and will not adversely impact the chemical and volume control system. Furthermore, sources of primary grade water to* the POTT will be isolated to prevent . inadvertent dilution of the RCS. Therefore, an unreviewed safety question does not exist. Periodic Test Procedure (Safety Evaluation No.93-053) 03-18-93 Periodic Test Procedure 1-PT-17. 7, "Recirculating Spray HX Service Water Radiation Monitor Pump Test," was temporarily changed to install electrical jumpers to allow the consequence limiting safeguards (CLS) automatic start features of Unit 1 recirculating spray heat exchanger service water radiation monitor sample pumps 1-SW-P-5A, 1-SW-P-5B, 1-SW-P-5C, and 1-SW-P-5D to be tested. Installation of the electrical jumpers will not affect other systems or components.
The applicable Emergency Operating Procedures (EOP) will be revised to require verification that the subject pumps have automatically started upon receipt of a Hi Hi CLS signal. . The EOPs will also direct appropriate actions to minimize the potential for a radioactive release in the event the pumps do not start. Therefore, an unreviewed safety question does not exist. Electrical Corrective Maintenance Procedure Temporary Maintenance Operating Procedure (Safety Evaluation No.93-059) 03-25-93 Electrical Corrective Maintenance Procedure 2-ECM-2403-02, "RSS Transformer B Outage with Backfeed of Transfer Bus E," was developed and Temporary Maintenance Operating Procedure 2-TMOP-EPH-001, "Unit 2 34.5 KV Bus 5 and RSS Transformer B Outage," was revised to provide instructions for conducting an outage of 34.5 KV Bus Number 5. These procedures were performed with Unit 2 defueled on backfeed supplying the D and E transfer buses. Unit 1 was at power with safety systems and emergency diesel generators available.
Therefore, an unreviewed safety question does not exist.
