Surry Monthly Operating Report No. 97-07 Page 11 of 20 FACILITY CHANGES THAT DID NOT REQUIRE NRC APPROVAL MONTH/YEAR: July, 1997 Safety Evaluation 7-3-97 Safety Evaluation 97-085 was performed to evaluate the the best method for stabilizing the sample flow rate through the Waste Gas Decay Tank (WGDT) oxygen analyzer 1-GW-AIT-150A. This will be performed using a Supplemental Work Instruction (SWI).
Performance of the SWI will ensure that the oxygen analyzer will not be operated outside of its design capabilities and will not change the concentration, pressure or radioactivity level of the waste gas stored in the system. Additionally, performance of the SWI will not affect the ability to obtain grab samples of the gas stored in the Waste Gas System.
Therefore, an unreviewed safety question does not exist.
Safety Evaluation 7-7-97 Safety Evaluation 97-086 was performed to evaluate the contamination of the Primary Grade Water (PG) System originally assumed to be uncontaminated. IE Bulletin 80-10 contained provisions to allow continued operation with contaminated non-radioactive systems provided a 1 OCFR50.59 Safety Evaluation was performed.
The evaluation concluded that with a stuck open relief valve dumping the contents of a PG tank to the storm drains with only minimal Circulating Water/Service Water flowrate, the highest radionuclide activity concentration would be diluted far below the maximum ODCM release levels and the isotopic activity concentrations in the discharge canal would be lower than the 1 OCFR20 allowable limits. Therefore, an unreviewed safety question does not exist.
JCO 82-97-001, Rev. 3 Justification For Continued Operation (Safety Evaluation No.97-002 Rev. 3) 7-7-97 FS95-043 This revision to the Justification for Continued Operation (JCO) discusses the Unit 2 letdown weld failure on June 24, 1997 and subsequent repair. Subsequent analysis in accordance with NRG Generic Letter 91-18 requirements have determined that additional interim support is required on the letdown line.
This degraded and non-conforming condition has been reviewed and analyzed.
The previous letdown operational restrictions and support modifications made provide reasonable assurance that the letdown piping system and supports meet the structural integrity requirements outlined in Generic Letter 91-18 Section 6.13.
Therefore, an unreviewed safety question does not exist.
Updated Final Safety Analysis Report Change (Safety Evaluation 97-087) 7-10-97 Updated Final Safety Analysis Report Change FS95-043 reformats and revises Section 9.6, Sampling System, to correct/clarify operation and description of the normal and post-accident sampling systems in use at the station.
These changes are administrative in nature and made to accurately reflect the current plant condition.
None of the changes to the UFSAR increases the probability of occurrence or increases the consequence of an accident. Therefore, an unreviewed safety question does not exist.
TM S2-97-005 TM S2-97-006 SE 97-0041 e
Surry Monthly Operating Report No. 97-07 Page 12 of 20 FACILITY CHANGES THAT DID NOT REQUIRE NRC APPROVAL MONTH/YEAR: July, 1997 Temporary Modification 7-14-97 (Safety Evaluation No.97-083 Rev. 1)
This Temporary Modification (TM) decreases the low charging flow setpoint for Annunciator 20-E-5 (CHRG PP TO REGEN HX HI-LO FLOW). This was performed to eliminate a distraction to the Unit 2 Operations Staff due to the annunciator alarming frequently as a result of reduced charging flow conditions operating with only 2-CH-HCV-2200A Letdown Flow Orifice in service.
The charging low flow setpoint for this annunciator is being decreased by this TM, but the high flow alarm capabilities will be maintained at its normal setpoint. Annunciator 20-F-3, REGEN HX LTDN LINE HI TEMP, will be functional to provide alternate indications for low charging flow. This condition does not affect accidents previously evaluated, does not create the potential for an accident not previously identified, and Technical Specification compliance is maintained. Therefore, an unreviewed safety question does not exist.
Temporary Modification (Safety Evaluation No.97-089) 7-15-97 This Temporary Modification (TM) connects a Dranetz Power Supply Monitor recorder.
This will allow the troubleshooting of the NRG Monitor power supplies to the Radiation Monitoring Cabinet O-RM-CAB-100.
The Radiation Monitoring System for secondary and ProcessNent Vent Systems utilizes redundant indications. The installed radiation monitoring indications and alarm functions will be unaffected by this TM. Therefore, an unreviewed safety question does not exist.
Safety Evaluation 7-17-97 Safety Evaluation 97-0041 was performed to evaluate the effect of losing three threads in one of the lid bolt holes in TN-32 Cask No. 3.
While the bolt threads are not specifically mentioned in the TN-32 Topical Safety Analysis Report (TSAR), the strength of the lid bolt engagement is discussed in various chapters of the TSAR. Transnuclear, Inc. has determined that 1.52 inches of threaded bolt shank are required to be engaged in the bolt hole threads to maintain the full strength of the bolt.
Even if three threads in the hole are damaged, 1.56 inches of thread bolt shank will be engaged (this assumes the worst case design tolerances). Therefore, an unreviewed safety question does not exist.
e Surry Monthly Operating Report No. 97-07 Page 13 of 20 FACILITY CHANGES THAT DID Nor REQUIRE NRC APPROVAL MONTH/YEAR: July, 1997 JCO 81-97-002, Rev. 0 Justification For Continued Operation (Safety Evaluation No.97-091) 7-25-97 JCO C-97-004, Rev. 0 This Justification For Continued Operation evaluates the impact of elevated levels of hydrogen in the containment atmosphere and supports the interim hydrogen concentration limit of 0.8%. The evaluation supports the 0.8% hydrogen concentration with the following limiting conditions: 1) continued operation of the containment upper dome air fan and pressurizer cubicle ventilation while at power and 2) hydrogen sampling program confirms bulk concentrations do not exceed the 0.8% limit.
The initial presence of 0.8% hydrogen in containment will have a negligible impact on the containment peak pressure, depressurization and pump NPSH analyses.
The self-imposed administrative limit of 0.8% is bounded by the conservatism assumed in the post-LOCA hydrogen analysis which include the one day hydrogen recombiner start time and the 50 scfm flowrate through the recombiner.
Therefore, an unreviewed safety question does not exist.
Justification For Continued Operation (Safety Evaluation No.97-094) 7-31-97 A review of the Appendix R fire safe shutdown Fire Contingency Action (FCA) procedures determined that the methodology for ensuring the proper ventilation alignment did not fully meet 10CFR50 Appendix R criteria. To provide the proper ventilation line up to support cooling of the Charging Pumps during an Appendix R event, a PAR to the Fire Contingency Action (FCA) Ventilation Attachment procedures was written as a compensatory measure.
The PAR written to the FCA Ventilation Attachment procedures allows the proper ventilation line up to support cooling of the Charging Pumps during an Appendix R event.
Therefore, an unreviewed safety question does not exist.

PROCEDURE OR METHOD OF OPERATION CHANGES THAT DID NOT REQUIRE NRC APPROVAL MONTH/YEAR: July, 1997 Instrument Periodic Test Procedure (Safety Evaluation 97-088)
Surry Monthly Operating Report No. 97-07 Page 14 of 20 7-11-97 Instrument Periodic Test Procedures 1-IPT-CC-RC-L-459, "Pressurizer Level Protection Loop L-1-459 Channel Calibration," One Time Only PAR allows required on-line corrective maintenance/testing of the pressurizer level control circuit following comparator LC-1-4590 replacement without an unnecessary system actuation. This maintenance is needed to restore the pressurizer level control loop to its designed configuration and function.
Letdown isolation 1-CH-LCV-1460A will be temporarily rendered inoperable by this activity.
However, the in-series valve 1-CH-LCV-1460B will remain fully functional. Additionally, the Safety Injection (SI) signal (unaffected by this activity) will. automatically close letdown isolation trip valves 1-CH-TV-120A/B.
As an added measure of protection, AP-16.0, "Excessive RCS Leakage," will verify the isolation function.
Therefore, an unreviewed safety question does not exist.
Temporary Operating Procedure (Safety Evaluation 96-036 Rev. 2) 7-21-97 1-RC-TV-1519A was declared inoperable due to erratic stroke times. This action requires the valve to fail closed to assure containment integrity. However, this valve is the supply valve for primary grade (PG) water to the containment. A jumper hose will be installed between 1-PG-154 and 1-RC-166 to allow PG water to bypass 1-RC-TV-1519A.
The modification will be installed and managed under administrative control. When not required, the isolation valves will be closed. When open, the administrative controls will require continuous monitoring by an operator who will close 1-RC-166 within 40 seconds of notification to ensure closure within 60 seconds of a Containment Isolation Signal.
Therefore, an unreviewed safety question does not exist.
Instrument Periodic Test Procedure (Safety Evaluation 97-092) 7-24-97 Instrument Periodic Test Procedures 1-IPT-CC-RC-L-459, "Pressurizer Level Protection Loop L-1-459 Channel Calibration," One Time Only PAR allows required on-line corrective maintenance/testing of the pressurizer level control circuit following corrective maintenance without an unnecessary system actuation.
This maintenance is needed to restore the pressurizer level control loop to its designed configuration and function.
Letdown isolation 1-CH-LCV-1460A will be temporarily rendered inoperable by this activity.
However, the in-series valve 1-CH-LCV-1460B will remain fully functional. Additionally, the Safety Injection (SI) signal (unaffected by this activity) will automatically close letdown isolation trip valves 1-CH-TV-120A/B.
As an added measure of protection, AP-16.0, "Excessive RCS Leakage," will verify the isolation function.
Therefore, an unreviewed safety question does not exist.

The first issue deals with a fire in the main control room with no means to isolate the affected Vital Bus panel from the associated Uninterruptable Power Supplies (UPS). This postulated event could potentially affect the associated UPS and, therefore, affect the downstream Appendix R Panel which could affect the Remote Monitoring Panel, the Emergency Diesel Generator Isolation Panels and Vital Bus Panels feeding Appendix R communications equipment. Secondly, Chapter 9 of the Appendix R Report indicates that proper selective tripping is required for faults on Vital Bus branch circuits. A high fault current could result in the main breaker tripping simultaneously with, or in lieu of, the branch circuit breaker. All Vital Bus Panels are potentially affected by this issue. Compensatory measures implemented in the FCAs will a) disconnect the feeder conductors routed to the control room at UPSs 1A1, 1A2, 2A1, and 2A2 for a main control room fire to ensure the availability of distribution panels located in the ESGR 1 and 2 fire areas and b) restore Control Room or ESGR Vital Bus distribution panels lost as a result of fire induced hot shorts and mis-coordination between the main and branch circuit breakers as needed to accomplish safe shutdown. These compensatory measures do not adversely impact the Class 1 E electrical distribution system.
Therefore, an unreviewed safety question does not exist.
