SUMMARY

OF OPERATING EXPERIENCE MONTHNEAR: February 1999

  • The following chronological sequence by unit is a summary of operating experiences for this month that required load reductions or resulted in significant non-load related incidents.
  • UNIT ONE:

02/01/99 0000 Unit starts the month at 100% / 845 MWe.

02/28/99 2400 Unit finishes the month at 100% / 855 MWe.

UNITTwo:

02/01/99 0000 Unit starts the month at 100% / 860 MWe.

02/04/99 1006 Commenced unit ramp down to perform 2-0SP-TM-001, Turbine Inlet Valve Freedom Test.

Unit at 100% / 855 MWe.

02/04/99 1045 Stopped ramp. Unit at 90% / 780 MWe.

02/04/99 1428 Commenced unit ramp down. Unit at 90% / 778 MWe.

02/04/99 1438 Stopped ramp. Unit at 88% / 766 MWe.

02/04/99 2035 Commenced ramp up. Unit at 88% / 760 MWe.

02/04/99 2245 Reactor power at 99.5% / 855 MWe, slow ramp to 100% in progress.

02/04/99 2340 Unit at 100% / 860 MWe.

e Surry Monthly Operating Report No. 99-02 Page 10 of 16 FACILITY CHANGES THAT DID NOT REQUIRE NRC APPROVAL MONTHNEAR: February 1999 DCP 97-059 Design Change Package 05/04/98 (Safety Evaluation 98-051)

Design Change Package 97-059, "Containment Spray (CS) Chemical Addition Tank (CAT)

Supply Valves Replacement", replaces the existing Unit 1 CAT Isolation Valves to eliminate the leakage of the CAT contents into the CS system piping.

DCP 98-008 Design Change Package 02/25/99 (Safety Evaluation 98-110, Rev. 1)

Design Change Package 98-008, "Containment Radiant Energy Shields", installs Marinite board and stainless steel in containment that either replaces or sheaths existing Thermo-Lag material to perform as radiant energy shields. The installation of the Marinite board and stainless steel will provide a noncombustible radiant energy shield in accordance with NRC requirements. Revision 1 uses suitcase latches on the front face panel of two boxes to allow quick and repeatable removal of the panel for future maintenance work on transmitters.

TM S1-99-001 Temporary Modification 02/03/99 (Safety Evaluation 99-006)

Temporary Modification S1-99-001 was used to install a temporary temperature calibrator for a thrust bearing temperature thermocouple for a Circulating Water pump.

DCP 97-048 Design Change Package 02/04/99 (Safety Evaluation 99-007)

Design Change Package 97-048, "Fuel Handling Manipulator Crane Electrical Upgrades",

describes the replacing of the Control Panel, Motor Control Center (MCC) and related cables and controls to the Fuel Handling Manipulator Crane in Containment.

DCP 98-053 Design Change Package 02/25/99 FS99-005 UFSAR Change Request (Safety Evaluation 99-009)

The recirculation line for the Unit 2 Low Head Safety Injection (LHSI) pumps will be relocated to originate at the upstream side of each pump's discharge side check valve. This will reduce the potential for pump damage when the pumps operate in a parallel operating configuration and are recirculating back to the Refueling Water Storage Tank (RWST).

DCP 97-032 Design Change Package 02/25/99 (Safety Evaluation 99-010)

The Unit 2 Main Control Room 'A' through 'K' annunicator panels will be replaced with larger panels. This activity will be performed while the unit is defueled and increased monitoring and compensatory measures will be implemented while the affected annunciator panels are removed from service for system change out.

Temporary Modification S1-99-002 installs a remote gravity oil addition system to the lower motor reseNoir of Unit 1 Reactor Coolant pump 1B. The purpose of adding the system is to reduce radiation exposure to the workers entering containment to add the oil.

Operating Procedure, 2-0P-CN-013, "Manual Regeneration of Condensate Polishing Resin", was revised for installation of a Temporary Modification (TM) to close valve 2-CP-AOV-241 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.
