e Surry Monthly Operating Report No. 98-12 Page 10 of 19 FACILITY CHANGES THAT DID NOT REQUIRE NRC APPROVAL MONTHNEAR: December 1998 DCP 91-003 Design Change Package 12/16/98 (Safety Evaluation 91-035)

Design Change Package 91-003, "Chemical Injection of Service Water 48" Headers", allows for the injection of sodium hypochlorite (chlorine) into the standby 48" Service Water (SW) headers to eliminate biofouling.

DCP 93-089 Design Change Package 12/07/98 (Safety Evaluation 94-160)

Design Change Package 93-089, "High Level Intake Structure Seal Plate Modifications",

installs casters on the corners of the seal plates located at the High Level Intake Structure making the seal plates less prone to binding during High Level isolation.

DCP 96-009 Design Change Package 12/16/98 (Safety Evaluation 96-030)

Design Change Package 96-009, "Emergency Service Water Pump Modification", replaces Emergency Service Water (ESW) pump 1-SW-P-1A with a spare pump that will require several modifications to accommodate differences in drive shaft diameter, angle drive lube oil cooler, and motor drive.

DCP 97-003 Design Change Package 12/16/98 (Safety Evaluation 97-033)

Design Change Package 97-003, RCP Motor Upper Bearing Oil Level Alarm Modifications",

modifies reactor coolant pump (RCP) motor (serial number 2S-76P049) bearing oil system to help prevent erroneous oil level indications in the oil sightglass and from the oil level alarm assemblies.

FS98-046 UFSAR Change Request 12/03/98 (Safety Evaluation 98-127)

UFSAR Change Request FS98-046 revises section 14.4.2.1 and table 9.1-6 to reflect the new volume control tank (VCT) rupture radiological analysis. The UFSAR VCT rupture radiological analysis assumed a letdown flow rate of 60 gallons per minute with delay of 5 minutes before the VCT is assumed to be isolated. The VCT rupture was re-evaluated using an assumed letdown flow rate of 160 gallons per minute with a delay of 25 minutes. The new analysis is consistent with actual plant operation.

FS98-050 UFSAR Change Request 12/08/98 (Safety Evaluation 98-128)

UFSAR Change Request FS98-050 changes the test frequency for the Intercept and Reheat Stop Valves from quarterly to every 18 months to eliminate part of the transient placed on the unit when performing the turbine inlet valve freedom test. The changing of the test interval from three months to eighteen months is based on a report provided by Westinghouse dated December 1998 (Evaluation of Turbine Missile Ejection Probability Resulting From Extending The Test Interval of Interceptor and Reheat Stop Valves at Surry Units 1 & 2).

e e Surry Monthly Operating Report No. 98-12 Page 11 of 19 FACILITY CHANGES THAT DID NOT REQUIRE NRC APPROVAL MONTHNEAR: December 1998 TM S1-98-026 Temporary Modification 12/09/98 (Safety Evaluation 98-129)

Temporary Modification S1-98-026 was used to remove the isolation valve manifold for the "A" Steam Generator Channel IV Main Steam Transmitter, 1-MS-FT-1475, and install a temporary equalizing valve in place of the isolation valve manifold.

TM S1-98-026 Temporary Modification 12/10/98 (Safety Evaluation 98-129, Rev. 1)

Temporary Modification S1-98-026 was used to remove the isolation valve manifold for the "A" Steam Generator Channel IV Main Steam Transmitter, 1-MS-FT-1475, and install a temporary equalizing valve in place of the isolation valve manifold. The new temporary valve was to be relabeled with a new mark number. Revision 1 of Safety Evaluation 98-129 eliminated the change to station labeling.

FS98-026 UFSAR Change Request 12/10/98 (Safety Evaluation 98-130)

UFSAR Change Request FS98-026 corrects the description of initial testing performed to verify the performance of the Recirculation Spray (RS) system. UFSAR Section 6.3.1.5.2 currently states that the initial test for the recirculation spray subsystem is identical to that for the containment spray subsystem". Based on the results of the RS system integration review performed as part of the Integrated Configuration Management project, the pre-operational testing of the RS system was determined not to be identical to the description of the Containment Spray system. This UFSAR change reflects the actual initial start-up testing performed for the RS system.

FS98-027 UFSAR Change Request 12/10/98 (Safety Evaluation 98-131)

UFSAR Change Request FS98-027 contains corrections and clarifications to the UFSAR sections that discuss Surry's Containment Spray (CS) system as a result of the Integrated Configuration Management project review of the CS system. These changes are to enhance accuracy and do not affect any CS system or structure, or any of its component's operation or performance.

SE 98-132 Safety Evaluation 12/17/98 Safety Evaluation 98-132 evaluates the approximately 200 irradiated fuel assembly insert components (burnable poison rod assemblies, thimble plug assemblies and rod control cluster assemblies) being consolidated and placed in 2 disposable cask liners. Each liner will then be placed in a TN-RAM shipping container and prepared for shipment to Barnwell, S. C. for burial.

e e Surry Monthly Operating Report No. 98-12 Page 12 of 19 PROCEDURE OR METHOD OF OPERATION CHANGES THAT DID NOT REQUIRE NRC APPROVAL MONTH/YEAR: December 1998 1-IPT-CC-MS-F-475 Instrument Periodic Test Procedure 12/03/98 (Safety Evaluation 98-126)

Instrument Periodic Test Procedure, 1-IPT-CC-MS-F-475, "Steam Line Flow Protection Loop F-1-475 Channel Calibration", was changed to contain steps for installation and removal of a Temporary Modification (TM) to bypass inoperable Channel 4 Steam Flow to allow surveillance testing to be performed on channels 1,2,3 and 4 of Unit 1. Technical Specifications compliance will be maintained during this evolution.

O-MOP-BS-001 Maintenance Operating Procedure 12/21/98 (Safety Evaluation 98-133)

Maintenance Operating Procedure, O-MOP-BS-001, "Establishing Administrative Control of the Control Room Pressure Boundary", ensures administrative control will be established when Control Room Pressure Boundary doors are open for maintenance or inspection.

1-0P-CN-013 Operating Procedure 12/22/98 (Safety Evaluation 98-134)

Operating Procedure, 1-0P-CN-013, "Manual Regeneration of Condensate Polishing Resin", was revised for installation of a Temporary Modification (TM) to close valve 1-CP-AOV-141 which will allow the anion resin to be transferred from the anion tank to the cation tank to be regenerated with sulfuric acid to remove chloride impurities which were loaded onto the resin during the recent Unit 1 startup.

0-1 PM-RM-G-004&005 Instrument Preventive Maintenance Procedures 12/22/98 CAL-817 Calibration Procedure (Safety Evaluation 98-135)

Procedures, O-IPM-RM-G-004, "Laundry Radiation Monitor RIC-4 Channel Calibration" and O-IPM-RM-G-005, "Laundry Radiation Monitor RIC-3 Ratemeter Calibration", were developed and procedure Cal-817, "Model 942 Log Ratemeter Scintillation Detector Source Calibration", was revised to install a Temporary Modification (TM) to allow for the calibration, repair and testing of the digital ratemeters without causing their control function to occur.
