JULY 1990 --------SERVICE WATER AND CIRCULATING WATER BUTTERFLY VALVE REPLACEMENT This design change replaced 96 11 , 42 11 , 36 11 and 30 11 circulating and service water butterfly valves and expansion joints. The replacement valves are ductile iron with the wetted portions coated with a liquid epoxy. The following valves and expansion joints were replaced and reported in July 1988: MOV-CW-106A,B,C,D MOV-SW-102A 1-SW-25,29,33,37 CW inlets SW to CC HX CC HX SW inlets The following valves have been replaced which completes the design change: MOV-CW-lOOA,B,C,D MOV-SW-lOlA,B 1-SW-27,31,35,39 CW outlets SW to BC HX CC HX SW outlets The replacement valves and expansion joints are one for one replacement of existing equipment and are designed to specification requirements which meet or exceed the original specifications.

The equipment will operate and function identically to existing equipment.

The new valves and expansion joints do not affect or change the basis for any Technical Specification.

The replacement valves are seismically qualified.

ADMINISTRATIVE CONTROL (Safety Evaluation

  1. 90-0167) 07/05/90 The missile plug above the 1 A 1 main steam non-return valve was removed to permit maintenance to be performed inside the steam side of Unit 2 safeguards.

Administrative control was assigned to reinstall the plug in the event of severe weather warnings.

Personnel will be standing by with the tools and equipment necessary to quickly reinstall the missile shield in the event of severe weather warnings (hurricane, tornado, or severe thunderstorm watch/warning).

An unreviewed safety question is not created. 10 e FACILITY CHANGES THAT DID NOT REQUIRE NRC APPROVAL MONTH/YEAR:

JULY 1990 -------1/2-EWR-89-518 ENGINEERING WORK REQUEST 07 /11/90 C-S2-90-0718 AC-Sl-90-0727 This request removed the gravel and installed a new single ply membrane roofing on the turbine building.

This change involved repairs to the turbine building roof. An unreviewed safety question does not exist. ADMINISTRATIVE CONTROL (Safety Evaluation

  1. 90-0175) 07 /18/90 This change ensures that containment integrity can be maintained in accordance with the definition of containment integrity in Technical Specification 1.0 with the outside Instrument Air supply manual isolation valves open. Administrative control over 2-IA-703 and 2-IA-704 in accordance with SUADM-0-026 ensures the ability to maintain containment integrity as defined in Technical Specification.

The valves will be closed upon notification by the main control room. In addition, control over the valves will ensure the ability to .maintain the containment partial pressure within the limits established by T.S. 3.8. Therefore, an unreviewed safety question is not created. ADMINISTRATIVE CONTROL (Safety Evaluation

  1. 90-0187) 07/27/90 This change ensures that containment integrity can be maintained with the manual letdown leakage monitoring valve opened intermittently.

Administrative control over 1-CH-440 ensures the ability to maintain containment integrity as defined in Technical Specifications.

The valve will be closed immediately upon notification by the main control room. Therefore, an unreviewed safety question is not created. 11 e e FACILITY CHANGES THAT DID NOT REQUIRE NRC APPROVAL MONTH/YEAR:

JULY 1990 --------SPS 1, CYCLE 10 MEMO DATED 07/27/90, SPS CYCLE 10 TEMPERATURE/POWER COASTDOWN OPERATING AT REDUCED NOMINAL OPERATING PRESSURE 07/27/90 (Safety Evaluation

  1. 90-0188)

This change determined the impact on continued operation for the remainder of Surry 1, Cycle lOA at a reduced nominal operating pressure of 2135 psig. The pressure will be reduced to attempt to reseat the pressurizer safety valve 1 A 1 which appears to be experiencing a small amount of reactor coolant leakage. A review of the applicable accident analyses show that the operation of Surry Unit 1 Cycle lOA in a temperature coastdown mode at a reduced reactor coolant system operating pressure of 2135 psig is acceptable.

Current accident analysis margins are conserved.

Changes to protection setpoints or other compensatory measures are not required to support implementation of the pressure reduction.

The same conclusions can be drawn for an extended pressure reduction of 150 psi (down to 2085 psig) provided the hi~h pressurizer pressure reactor trip setpoint is reduced by 50 psi (from 2385 psig to 2335 psig). The extension of operation into the power coast region is also covered by this evaluation in that thermal margins will continue to increase as temperature and power are reduced. 12 l/2-0P-4.22 1/2-0P-23.2.4 PROCEDURE OR METHOD OF OPERATION CHANGES THAT DID NOT REQUIRE NRC APPROVAL MONTH/YEAR:

JULY 1990 OPERATING PROCEDURE (Safety Evaluation

  1. 90-0169) 07/06/90 This change secured and restarted the spent fuel pit cooling pump. The cooling pump is secured to prevent handling cask and fuel in turbulent water flow. Fuel pit cooling removes the heat from the pool. To secure the cooling pump will result in an increase in temperature but will allow easier handling of the cask and fuel. The heatup of the pool and additional surveillance is bounded by the UFSAR. Therefore, an unreviewed safety question does not exist. OPERATING PROCEDURE 07/18/90 * (Safety Evaluation
  1. 90-0176)

This change deleted the requirements in the operating procedure for a 60 day hold up of the 1 8 1 waste gas decay tank (WGDT) under normal evolutions.

The 1 8 1 WGDT is presently at approximately 100 PSIG and has been in holdup for eight days. The WGDT is provided to accommodate the volume of gasses generated during normal operations of both reactor units and is designed under normal operation for a 30 day filling period followed by a 20 day holdup period and a 10 day bleed period. Procedural controls normally provide additional holdup time of at least 45 days to allow decay time for the accumulated gasses. Due to the recent large amounts of gas generated by the preparations for maintenance on the gas stripper system, the 1 8 1 WGDT will be released with only eight days of holdup. Radioactive gaseous release permits have been approved by the Health Physics Department for this release. The total activity in the tank is approximately 0.2 µCi/ml. The primary gaseous constituent being XE-133. This volume of activity is much less than that assumed in the UFSAR to be released upon rupture of the WGDT with one percent failed fuel. Further, the release rates are to be restricted to three standard cubic feet per minute (SCFM) and the release will be continually monitored and can be immediately terminated, if required.

The calculations performed at the above release rate show that the total activity released and the site boundary doses are much less than that allowed by Technical Specifications.

Therefore, an unreviewed safety question is not created. 13 2-ST-213 2-ST-223 2-ST-240 e e TESTS AND EXPERIMENTS THAT DID NOT REQUIRE NRC APPROVAL MONTH/YEAR:

~~JU_L_Y_l....:.9...:...90_;:__~

SPECIAL TEST 08/02/89 This test verified/adjusted the setpoints of the valves listed below. VALVE SV-MS-201A,B,C SV-MS-202A,B,C SV-MS-203A,B,C SV-MS-204A,B,C SV-MS-205A,B,C SETPOINT 1085 psig 1095 psig 1110 psig 1120 psig 1135 psi g PLUS 1% BAND ORIFICE SIZE 1074-1095 psig 1084-1105 psig 1098-1121 psig 1108-1131 psi g 1123-1146 psi g 6 R R R R This test did not create an unreviewed safety question because the main steam system is not required for core cooling at cold shutdown.

SPECIAL TEST 08/22/89 This test was performed to prove the operability of each inside recirculation spray pump to perform its intended function by measuring flow through a special recirculation test loop. This test also established reference values for inside recirculation spray pump testing in accordance with ASME Section XI, Subsection

!WP. The test was performed at cold shutdown conditions utilizing equipment installed specifically for the test. The pumps are not required to be operable below 350°F/450 psig. Following the test, the system piping was returned to a normal configuration.

The test was performed at cold shutdown and the system returned to a normal configuration following the test. An unreviewed safety question was not created. SPECIAL TEST 09/11/89 The purpose of this test was to functionally test the sequencing of loads onto Emergency Bus 2H following the injection of an engineered safeguards feature (ESF) signal. An undervoltage signal was injected five minutes after the initial ESF signal to verify that the required loads are tripped off the emergency bus and that they are re-sequenced on the emergency bus in the required order. An unreviewed safety question was not created since one train of the main control room air bottle system was available for automatic actuation on Unit 1 safety injection; the other train was manually isolated and under administrative control to be opened within one minute of a Unit 1 safety injection.

One train of air bottles is sufficient to pressurize the main control room/relay room boundary for one hour following a design basis accident.

14 2-ST-249 2-ST-254 2-ST-263 2-ST-273 e e TESTS AND EXPERIMENTS THAT DID NOT REQUIRE NRC APPROVAL MONTH/YEAR:

JULY 1990 -------SPECIAL TEST 09/03/89 This test was performed to measure the combined leakage of service water header isolation valves 2-SW-MOV-202A/B.

This leakage value was combined with the leakage values for the circulating water valves, and other service water valves to quantify the total leakage flow for the station. The test was performed with the unit in cold shutdown conditions and the Technical Specification Limiting Conditions of Operation were met prior to commencement of the test. No safety related equipment or equipment important to safety utilize service water supplied through the piping were isolated during the test. An unreviewed safety question was not created. SPECIAL TEST 08/02/89 This test was performed to verify that when the identified breaker is open on vital buses, DC panels, or MCC 1 s, that the valves shown to be connected to that breaker will not cycle. The test was performed at cold shutdown conditions and the Limiting Conditions for Operation were satisfied prior to commencement of the test. The probability of accidents analyzed in the FSAR were not increased, and the possibility of new accidents was not created. Redundant equipment was operable during the test. An unreviewed safety question was not created. SPECIAL TEST 10/10/89 This test was performed to obtain trending data for auxiliary feedwater full flow to each steam generator from auxiliary feedwater pump 2-FW-P-3A and 2-FW-P-38 with and without the use of the auxiliary feedwater booster pumps 2-FW-P-4A and 2-FW-P-48.

This test simulates auxiliary feedwater flow operation and did not prevent the system from performing its intended function.

An unreviewed safety question was not created. SPECIAL TEST 02/06/90 This test was performed to obtain trending data for auxiliary feedwater full flow to each steam generator for auxiliary feedwater pump 2-FW-P-2 with and without the use of auxiliary feedwater booster pumps 2-FW-P-4A and 2-FW-P-48.

This test simulates auxiliary feedwater flow operation and did not prevent the system from performing its intended function.

An unreviewed safety question was not created. 15
