e Surry Monthly Operating Report No. 96-07 Page 10 of 16 FACILITY CHANGES THAT DID NOT REQUIRE NRC APPROVAL MONTHNEAR: July, 1996 TM 82-96-020 Temporary Modification 01-96 (Safety Evaluation No.96-092)

Temporary Modification (TM) 82-96-020 temporarily removed the main control room annunciator card for annunciator C-F-2, RCP BRG HI TEMP. The TM was implemented to stop a continuous alarm condition associated with the reactor coolant pump temperature recorder, TE-2-448, until the recorder setpoints were changed.

Annunciators C-F-2 and C-F-1, RCP 1C CC RETURN HI TEMP were disabled while the annunciator card was removed. Indication of the affected parameters remained available and monitoring was increased. The instrument channels associated with the subject annunciators remained operable since control and protection functions were not affected.

Therefore, an unreviewed safety question does not exist.

TM 82-96-019 Temporary Modification 7-02-96 (Safety Evaluation No.96-095)

Temporary Modification (TM) 82-96-019 installed a mechanical jumper to provide a continuous vent path from the Unit 2 pressurizer relief tank (PRT) through the primary drains tank (PDT) to the overhead gas system. This TM is necessary to maintain acceptable PRT pressure until pressurizer safety valve leakage could be corrected. The procedures associated with chemistry sampling evolutions that are affected by this TM were revised appropriately.

The mechanical jumper is rated for system pressure and allows PRT gases to vent to the overhead gas system which is designed for processing, holding, and monitoring radioactive gases. The TM did not impact the reactor protection system, safety injection system, consequence limiting safeguards system, or containment integrity. Therefore, an unreviewed safety question does not exist.

TM 81-96-013 Temporary Modification 7-03-96 (Safety Evaluation No.96-096)

Temporary Modification 81-96-013 installed a blank flange on the 1-CP-DM-1A condensate polisher resin transfer line to facilitate the repair of valve 1-CP-AOV-5A.

The 1-CP-DM-1 A condensate polisher will be removed from service while the blank flange is installed. The TM will not adversely affect the operation of condensate polishing system or the operation of any safety-related system or component. Therefore, an unreviewed safety question does not exist.

FS 96-07 Updated Final Safety Analysis Report Change 7-22-96 (Safety Evaluation 96-098)

Updated Final Safety Analysis Report Change 96-07 revised Section 11.3.4.3, "Containment Gas Monitors," to correct the count rate values for isotopes Xe, 33 and Kr85.

These changes were administrative in nature and will not result in any unmonitored release or cause the limits of GDC 19 or 1O CFR 100 to be exceeded. Therefore, an unreviewed safety question does not exist.

e Surry Monthly Operating Report No. 96-07 Page 11 of 16 FACILITY CHANGES THAT DID NOT REQUIRE NRC APPROVAL MONTH/YEAR: July, 1996 FS 96-25 Updated Final Safety Analysis Report Change 7-22-96 (Safety Evaluation 96-097)

Updated Final Safety Analysis Report Change 96-25 revised Section 9.4.4.1, "Component Cooling Water System Availability and Reliability," to delete the reference to the automatic closure function of the primary drain coolers component cooling (CC) return line hand control valves 1[2]-CC-HCV-114[214].

This change was administrative in nature and was made to accurately reflect the current plant condition. The automatic closure function of the subject valves was originally installed to isolate the CC system (to prevent an overpressure condition) in the event of a primary drain cooler tube rupture. This closure function was subsequently removed during the initial startup of each unit since the potential for the CC system to become overpressurized from the primary drain cooler was not considered to be a credible event.

Therefore, an unreviewed safety question does not exist.

SE 96-099 Safety Evaluation 7-22-96 Safety Evaluation 96-099 assessed the continued operation of Units 1 and 2 while the Unit 2 power supply to the common radiation monitor cabinet, 1-RM-CAB-0-0, is out of service. The subject power supply was tagged out to facilitate the replacement of associated power supply cables.

The evaluation concluded that the affected radiation monitors, indications, alarms, and control functions continue to be capable of performing their required functions since they remain powered from an operable emergency backed power source. Therefore, an unreviewed safety question does not exist.

e Surry Monthly Operating Report No. 96-07 Page 12 of 16 PROCEDURE OR METHOD OF OPERATION CHANGES THAT DID NOT REQUIRE NRC APPROVAL MONTHNEAR: July, 1996 1[2]-0P-CS-002 Operating Procedures 7-02-96 1[2]-0P-CS-006 (Safety Evaluation No.96-094)

Operating Procedures 1[2]-0P-CS-002, "Refueling Water Chemical Addition Tank Operations," and 1[2]-0P-CS-006, "Draining the RWST," were revised to provide instructions for administratively controlling Containment Spray (CS) system valves 1-CS-112 and 1-CS-120 or 2-CS-97 and 2-CS-100 when performing the subject procedures.

Appropriate administrative controls are provided in the procedures to ensure that the subject valves are closed within six minutes of the initiation of a Hi Hi Consequence Limiting Safeguards signal. Closure of the valves within this time limit ensures that sufficient CS flow and Chemical Addition Tank (CAT) inventory is maintained for accident mitigation. Therefore, an unreviewed safety question does not exist.

1[2]-MOP-36.5 Maintenance Operating Procedures 7-22-96 (Safety Evaluation No.96-065, Revision 1)

Maintenance Operating Procedures 1[2]-MOP-36.5, "Secondary Plant Air lnleakage Inspection," were revised to provide instructions for the installation and removal of an Orbisphere oxygen monitor, in-line flow indicator, and a temporary sample header at the condensate pump discharge drain lines. The data obtained will be used to verify that the existing on-line oxygen monitor is operating properly.

The procedurally controlled temporary modifications do not adversely affect the operation of any component or system. Therefore, an unreviewed safety question does not exist.

FLOWCALC P-250 Computer Programs 7-29-96 CALCALC CALCCHK FLOWPRNT 1[2]-0PT-RX-001 Operations Periodic Test Procedures 1[2]-0PT-RX-002 (Safety Evaluation No.96-102) 1[2]-0PT-RX-003 1[2]-0PT-RX-004 Plant computer (P-250) programs FLOWCALC, CALCALC, CALCCHK, and FLOWPRNT and Operations Periodic Test Procedures 1[2]-0PT-RX-001, "Reactor Power Calorimetric Using CALCALC Computer Program," 1[2]-0PT-RX-002, "Reactor Power Calorimetric Using Steam Flow and P-250 Computer Points (Manual)," 1[2]-0PT-RX-003, "Reactor Power Calorimetric Using Feed Flow and P-250 Computer Points (Manual)," and 1[2]-

0PT-RX-004, "Reactor Power Calorimetric Using Feed Flow with P-250 Out of Service (Manual)," were revised to improve the accuracy and stability of calorimetric calculations.

The subject changes did not involve any hardware modifications and did not affect methods of operation or surveillance criteria. The accuracy of the calorimetric calculations remains within that assumed by the safety analysis. Therefore, an unreviewed safety question does not exist.
