Began power reduction to reduce dose rate to facilitate an investigation of a noted increase in reactor coolant leakage. Stopped power reduction at 50%, 400 MWe. Began power reduction to place unit at Cold Shutdown as required by Technical Specification 3.1.C.4 due to a non-isolable weld leak on the "C" reactor coolant pump seal injection line. Generator off-line.

Reactor manually tripped. Reactor critical.

Generator on-line. Began power increase.

Stopped power increase at 100%, 850 MWe. Unit operating at 100% power, 850 MWe. I Unit operating at 100% power, 855 MWe. Unit operating at 100% power, 845 MWe.

May, 1998 Design Change Package 05/07/98 . . Design Change Package 92-22 replaced various older model Unit 1 and Unit 2 operated valves (SOV) with newer models. The modification did not affect the original design function or operation of the SOVs. Temporary Modification (Safety Evaluation 98-056) 05/12/98 Temporary Modification S2-98-02 replaced the failed manual actuator for service water system isolation valve, 2-SW-478, with a valve handwheel.

Temporary Modification (Safety Evaluation 98-057) 05/14/98 Temporary Modification (TM) S1-98-12 installed a cap to isolate the failed capillary tubing on the discharge of the Unit 1 turbine bearing lift pump. Installation of the TM also isolated the pump discharge pressure gauge. Safety Evaluation 05/21/98 Safety Evaluation 98-060 was performed to assess the installation of a freeze seal to facilitate the replacement of Unit 1 reactor coolant system valve, 1-RC-6. The evaluation concluded that the installation of the freeze seal in accordance with Mechanical Corrective Maintenance procedure O-MCM-1918-03, "Freeze Seal of Piping," was acceptable.

Temporary Modification (Safety Evaluation 98-061) 05/24/98 Temporary Modification S1-98-13 installed a recorder on the acoustic monitors used to monitor the performance of the Unit 1 pressurizer safety valves;*

May, 1998 UFSAR Change (Safety Evaluation 98-052) Surry Monthly Operating Report No. 98-05 Page 11 of 16 05/04/98 . UFSAR Section 17.2, "Operational Quality Assurance Program Topical Report," was revised to reflect the replacement of the Instruction Manual for Architect/Engineers with a General

  • Nuclear Standard which describes the interface between the company and its contractors.
uFSAR Change 05/07/98 . (Safety Evaluation 98-053) UFSAR Section 7.2.3.2.7, "Anticipated Transient Without SCRAM (ATWS) Mitigation System Actuation Circuitry (AMSAC)," was revised to clarify the licensing basis associated with the AMSAC C-20 interlock setpoint.

Operating Procedure (Safety Evaluation 98-054) 05/11/98 Operating Procedure 1-0P-RC-011, "Pressurizer Relief Tank Operations," was changed to provide instructions for the installation of a mechanical jumper that connects the Unit 1 pressurizer relief tank (PRT) vapor space sample line to the overh.ead gas system. The jumper allows the PRT to be continuously vented to the overhead system without batch releasing to the process vent.

  • General Maintenance Procedure (Safety Evaluation 98-055) 05/12/98 General Maintenance Procedure GMP-011, "Installation and Removal of Stop Logs," was . changed to provide instructions for the installation of an electrical jumper that will enable the circulating water intake level alarms to remain functional in the event that one of the intake
