  • SECTION I INTRODUCTION Salem Generating Station is a PWR of 3338 MWt rated power, operated by Public Service Electric and Gas Company and located in Salem,
  • New Jersey. The Nuclear Steam Supply System is a Westinghouse 4-loop plant. The architect engineer was PSE&G Co., and the constructor was United Engineers and Constructors. The condenser
  • cooling method.is circulating water from the Delaware River. The plant is subject to license DPR-70 issued August 13, 1976, pursuant to Docket Number 50-272. The date of initial reactcr criticality was December 11, 1976, and commercial generation of power began
  • June 30, 1977.

This report was prepared by Mr. R. A. Silverio, Assistant to Manager (609-365-7000 Ext. Salem 510)

  • Major personnel changes during the e year included the Maintenance Engineer, Mr. R. A. Silverio being desig-nated as the Assistant to Manager while Mr. Stanley LaBruna assumed the position of Maintenance Engineer. Mr. James Gueller replaced Mr. Norman Millis as the Senior ~erformance Supervisor - Chemistry e and HP *

Initia1 criticality was achieved on December 11, 1976. After zero power physics tests were completed, the Unit was synchronized on

  • December 25, 1976 to complete the power escalation program. This program consisted of a combination of physics and plant response tests that were conducted at various power plateaus between 10%

and 100% power. This startup program was completed on July 30, 1977

  • with the generator trip test from 100% power, although the Unit was declared commercial on June 30, 1977.

. '

During the latter six months of the year the Unit operated at a e capacity factor of 42.5% for a total of 2,186,310 MWe hours. Unit load decreases were mostly due to the need for cleaning secondary system strainer.s as described in Section III, Summary of Operating Experience.

An eleven week outage was taken to complete the L-4 stage modification of shrouding on all low pressure turbines;

Piping System. The hangers added meet the present piping design criteria for the system and does not present an unreviewed safety question as defined in 10CFRS0.59.

4. The installation of the needle valve on the "E" port of solenoids
  • 5. Change required to correct testing deficiency to the Solid State Protection System general warning/reactor trip circuit as per NRC and safety requirements *
  • 6. This change is being made to increase system reliability only.

System failure analyses are not adversely affected. An unreviewed safety question does not exist in that addition of a series valve identical to the one already installed does not create a

  • possibility for an accident of a type previously reviewed, nor does 'it increase the probability of a presently reviewed accident or malfunction *
7. Proposed design change will not affect equipment operating characteristics. The proposed repair is based on manufacturers
  • recommendation to improve operating reliability per Allis Chalmers letter dated 10-20-76. Therefore, this modification does not involve any of the criteria of an unreviewed safety question per 10CFRS0.59 *
  • 8. The smaller size impeller will reduce the total pr~ssure head and w~ll reduce the erosion on chiller condenser 'tubes. This smaller size impeller will also meet the system requirements *
  • 9. Engineering re-evaluation of the system shows that the vent is not essential for continued safe operation of the system .

. Deletion of the vent will not detrimentally effect system

  • operation. The definition of an unreviewed safety question is not satisfied, the vent is not required for safe shutdown of the system.
  • ,- 10. This change will not increase the chance of an accident or malfunction as evaluated in the Safety Analysis Report or as evaluated by considering any other criteria. Margins .of safety as defined in the Tech. Spec. "will not be reduced. The. afore-
  • mentioned comments are accurate since this change only involves relocating small bore pipe in order to avoid interferences.
11. New design has been reviewed and determined not to create new
  • potential malfunctions or increase the probability of previously analyzed ~alfunctions or accidents.
  • 12. This change does not modify functional operation, it only adds monitoring circuitry. Additional circuitry cannot increase the probability of failures.
13. Modification does not degrade any safety related equipment, a9gravate any previously analyzed accident, or change the basis of any Technical Specification ..
  • 14. Change will reduce vibration but will not affect other performance characteristics. Performance of motors safety
l. function will not be not be affected by this change. Therefore,
  • no criteria of an unreviewed safety question are involved.
15. This design change does not affect any presently performed safety analysis nor does it create any new safety hazards *
  • The basis of the Technical Specifications are not affected.
16. Actually, there is no change, it is only recognition of slight differences of instrumentation between the Salem plant and the
  • Westinghouse RCP Manual. There is no unreviewed safety question.
17. The functional operation of the Pressurizer Spray Control Loop remains uncha~ged. Instruments are to be replaced to improve
  • system reliability.
18. Revision of Radiation Channel Rl8 setpoint based upon result of radiochemical analysis of waste holdup and/or monitoring
  • tanks, setpoint shall be in accordance with the Salem Environmental Technical.Specifications.
  • 19. Will remove foreign.material from liquid Freon and as such will prolo~g the life of the equipment. This item not discussed in FSAR, or Technical Specifications. No new failure modes for the system are introduced, nor are any present modes aggravated *
  • 20. Nonconservative direction setpoint change has been analyzed and determined to not reduce safety margins required by Technical Specifications basis *
  • 21. No change in system function and no failure modes would be created which could cause or increase the potential for acci:dents or malfunctions. Change will improve operational
  • reliability *
22. These circuits do not have any safety function. DCR was checked safety related due to interface with SSPS Test
  • Cabinets. Change ensures proper system operation consistent with original design criteria.
23. The change improves system operability and does not affect
  • the safety analysis for containment pressure/temperature transients. The additional relay does not add the potential for other failures which would negate the safety function of isolating service water to the Turbine Building *
24. Improves system operation by reducing transient pressures at Fan Cooler Units. Operational requ*irements are not affected *
