CHANGE TO FACILITY AS DESCRIBED IN THE FSAR TITLE: PCR-000489, Emergency Service Water (ESW) Auxiliary Feedwater (AFW)

Crossover Legs FUNCTIONAL

SUMMARY

This plant modification adds an orificed drain line with a loop seal to the ESW/AFW Crossover Piping. The spaces between the redundant valves separating the AFW suction and ESW system had previously been vented to prevent leakage from ESW to AFW. It was determined that on switch over to the ESW supply the resulting air _ bubble may damage the AFW pumps. The modification allowed the space to be filled with water and vented to a drain to accomodate any ESW leakage.

SAFETY

SUMMARY

.This change is intended to increase the reliability of the AFW system. The installation of the loop seal prevents the creation of an air-binding malfunction. This change does not increase the probability or consequences of an analyzed accident, nor does it create a new or different type of accident. This change improves the reliability of the AFW System and therefore does not significantly reduce the margin of safety.

TITLE: PCR-001174, Mode 2 Start-Up Steam Generator Low Pressure Interlock l

FUNCTIONAL

SUMMARY

The FSAR states that the Auxiliary Feedwater (AFW) System will be -used to adjust steam generator. water levels prior to an'd during plant start-up. This was necessary due to a Steam Generator Low Pressure interlock which prevented the use of the Condensate /Feedwater system to be used for this function. This change disables the interlock and allows the Condensate /Feedwater system instead of the AFW system to be used to adjust steam generator water levels prior to and during plant startup.

SAFETY

SUMMARY

The Steam Generator low pressure interlock does not protect equipment important to safety during specified plant conditions. This modification does not increase the probability or consequences of analyzed accidents nor introduce a different type of accident or equipment malfunction than already evaluated in the FSAR. Thus no unreviewed safety question exists.

CHANGE TO FACILITY AS DESCRIBED IN THE FSAR TITLE: FCR-FP-1133, Fire Seal Requirements in Non-rated Floors l

FUNCTIONAL

SUMMARY

This plant modification eliminates the requirements for fire seals in non-rated floors.

l SAFETY

SUMMARY

The F.P. Safe Shutdown Analysis takes no credit for fire seals located in non-rated floors. Fire seals in non-rated floors are not included as part of the protection described in the SSA. Eliminating fire seals for which no credit was taken does not affect the probability or consequences of a fire analyzed in the SSA. The plant margin of safety is not significantly reduced.

1 CHANGE TO FACILITY AS DESCRIBED IN THE FSAR TITLE: FCR-SP-292, Condensate Vacuum Pump Effluent Treatment System (CVPET).

Fan Inlet and Discharge Valve Modification FUNCTIONAL

SUMMARY

Due to orientation of CVPET Fan discharge valves moisture

-accumulates in the vertical duct adjacent to these valves. This plant modification relocates the outlet valve to a horizontal section downstream of the fan and deletes the inlet valve.

SAFETY

SUMMARY

The CVPET is a non-nuclear safety ventilation cleanup system and is not part of the radwaste management system. The purpose of these valves was to prevent air from recirculating through the idle fan.

Eliminating the inlet valve and relocating the outlet valve does not affect this function and does not affect any accident analysis or the margin of safety.

CHANGE TO FACILITY AS DESCRIBED IN THE FSAR TITLE: FCR-SI-1011 Rev. 3, Change to Emergency Diesel Generator Output Meters Range FUNCTIONAL

SUMMARY

FCR-SI-1011 resolved problems with the Emergency Diesel.

Generator varimeters reading downscale'and conflicts between design documents concerning correct _ polarity. Resolution of the problems included installation of new' scales on meters located on the Auxiliary Control Panel and the Main Control Board which differ in range than currently specified in FSAR Tables

'7.4.1-1 and 7.5.1-3 as indicated below. The following Diesel Generator Power indicators originally had a range of 0-8 MW and now have a range of 0-9.6 MW: EI-6957A2, EI-6957B2, EI-6957A1, EI-6957Bl. The following Diesel Generator Power indicator originally had a range of 0-6 MVAR and now has a range of 0-9.6 MVAR:'EI-6958A.

SAFETY

SUMMARY

The above change is to the meter scale range only and does-not effect the actual output of the Diesel Generator. This change does not increase the probability or consequences of analyzed accidents, nor introduce a different type of accident or equipment malfunction than already evaluated in the FSAR. Thus no unreviewed safety question exists.

CHANGE TO FACILITY AS DESCRIBED IN THE FSAR TITLE: FCR-I-3893 Rev. 1, Sequencer Test lA-SA FCR-I-3896 Rev. 1, Sequencer Test IB-SB FUNCTIONAL

SUMMARY

This plant modification consists of relay and wiring changes to prevent relay racing between the sequencer test and the sequencer program relays when the test operation is interrupted. As previously designed, if an accident condition occurred or testing was interrupted while testing of the sequencer internal circuits was in progress, all the circuits would de-energize in 5 seconds. This could result in the test relay de-energizing before the program relay thus initiating an ESF actuation.

Operation of the test relay is now delayed such that the sequencer program relays de-energize first and then the testing relays.

SAFETY

SUMMARY

The modification decreases any relay racing between sequencer test relays and program relays. The change does not increase the probability or consequences of analyzed accidents, nor introduce a different type of accident or equipment malfunction than already evaluated in the FSAR. Thus no unreviewed safety question exists.

CHANGE TO FACILITY AS DESCRIBED IN THE FSAR TITLE: Westinghouse Drawing (1766E37, Rev. 3) "Shearon Harris Unit 1 Core Loading Plan Cycle 1" and Revision 3 to the Unit 1 Core Component Loading Chart (PSAR Figure 4.2.2-13)

FUNCTIONAL

SUMMARY

The axial location of the californium source within the primary source rod was changed. The californium source in the primary source rod has been repositioned 8 and 1/2 inches higher in order to meet the Westinghouse requirement that the primary source be located mid plane of the source range detector. This change results in a change to FSAR Figure 4.2.2-13 (i.e., the bottom spacer height is now 41.0 inches, instead of 32.5 inches).

SAFETY

SUMMARY

The required minimum source range audible count rate is not changing. This change repositions the primary source in order to meet the requirement that it be located mid plane of the source range detector. As such, this change fulfills the original design requirements instead of revising them. The change does not increase the probability or consequences of analyzed accidents, nor introduce a different type of accident or equipment malfunction than already evaluated in the FSAR. Thus no unreviewed safety question exists.

.o CHANGE TO FACILITY AS DESCRIBED IN THE FSAR TITLE: PCR-000939, Digital Electric Hydraulic (DEH) System Load Rejection Capability FUNCTIONAL

SUMMARY

This plant modification enables the DEH system to successfully respond to a large generator load rejection. The previous configuration of the DEH system computer and fluid components were such that it was not capable of handling a large generator load rejection. As part of Westinghouse recommendations, the overspeed protection control setpoint was increased from 103% as described in FSAR Section 10.2.2.5 to 105% of the rated turbine speed.

SAFETY

SUMMARY

Increasing the overspeed protection control setpoint is necessary to enable the system to respond to a large generator load rejection. This change does not increase the probability or consequences of analyzed accidents, nor introduce a different type of accident or equipment malfunction than already evaluated in the FSAR. This does not impact on the turbine mechanical or electrical trip for overspeed which is 110% of rated speed. Thus no unreviewed safety question exists.

SUMMARY

This plant modification installs a nitrogen sparger in the RMWST in order to effectively strip dissolved oxygen from the contents of the tank. The supply of nitrogen to this sparger is limited by a one quarter inch pressure regulating valve and is normally discharged through four three inch non-nuclear safety vent valves. A six inch ASME Sect. III, Class 3 relief valve has been placed on the overflow of the tank for additional protection.

SAFETY

SUMMARY

The RMWST is not required for safe shutdown of the plant.

This modification does not increase the probability or consequences of analyzed accidents, nor introduce a different type of accident or equipment malfunction than already evaluated in the FSAR. Thus no unreviewed safety question exists.

MEM/HO-8704280/ PACE 28/OS1

CHANCE TO FACILITY AS DESCRIBED IN THE FSAR TITLE: PCR-000422, Feedwater Heater Vents and Drains FUNCTIONAL

SUMMARY

This is not a modification to the plant but is a correction to design documents.

FSAR Figure 10.1.0-5 describes the valves (1HD-157 and 1HD-457) on heater drain lines which come off the discharge side of the Heater Drain Pumps (1A & IB) going to the Sampling System as normally closed. This change will reflect the correct operation of the system on the design drawings and FSAR Figure by showing these valves as normally open.

SAFETY

SUMMARY

The Heater Drain System is a non-safety system and does not affeet safety related equipment. This change does not increase the probability or consequences of analyzed accidents, nor introduce a different type of accident or equipment malfunction than already evaluated in the FSAR. Thus no unreviewed safety question exists.

CHANCE TO FACILITY AS DESCRIBED IN THE FSAR TITLE Containment Cooling System Normal Operation FUNCTIONAL

SUMMARY

This plant modification revises the normal operation of the containment safety fan coolers dampers. The nozzle dampers are interlocked so that under normal operating conditions the dampers are positioned depending on the containment average temperature.

If the containment average temperature is below or equal to ll8'F, the nozzle dampers are closed. If the containment average temperature is above 118'F, the nozzle dampers for safety fan coolers AH-3 and AH-4 are open and the nozzle dampers for safety fan coolers AH-2 and AH-1 are closed.

SAFETY

SUMMARY

This plant modification affects operation of these dampers during normal operations only and do not affect safety fan cooler operations during an accident. This change is intended to enhance temperature control in the containment during normal operation. Operations during accident conditions are not affected. This plant modification does not increase the probability or consequences of an accident or malfunction of equipment important to safety.

It does not create a new or different type of accident or significantly reduce the margin of safety.

CHANGE TO FACILITY AS DESCRIBED IN THE FSAR TITLE: Radiation Monitoring

. FUNCTIONAL

SUMMARY

The design of the process radiation monitors for the Auxiliary Steam (AS) Condensate return was supplement ed to provide automatic termination of releases to the condenser or the auxiliary boiler and automatic isolation of the tank vents when radiation is detected in the AS condensate.

SAFETY

SUMMARY

The plant design uses an auxiliary steam system to provide process steam for radioactive waste evaporators. The steam used in these evaporators is condensed and collected for reuse.

In the'unlikely event that the steam side of the evaporator becomes contaminated due to leaks within the evaporator, the radiation monitors will provide isolation of the transfer of this water to a noncontaminated system such as the auxiliary boiler. These monitors were previously described in the FSAR, but the automatic isolation function was not. The addition of the isolation function provides a protection against the undetected release of radioactive material from the plant.

CHANGE TO FACILITY AS DESCRIBED IN THE FSAR TITLE ' Revision to Position on Regulatory Guide 1.38 FUNCTIONAL

SUMMARY

The PSAR li ts exceptions to ANSI 45.2.2 as endorsed by Reg. Guide 1.38.

This Reg. Guide deals with QA requirements for the storage of safety-related items prior to installation in the plant. The FSAR provides exceptions and clarifications with regard to this Reg. Guide. These items were supplemented with an additional exception to include the latitude to evaluate storage recommendations (including maintenance required during storage) made by the vendor in view of the specific storage condition provided at the plant.

If after evaluation, it is concluded that equivalent protection is provided, the vendors specific recommendation may be modified.

SAFETY

SUMMARY

The purpose of the regulatory recommendations is to assure that storage conditions do not degrade safety-related equipment. The change assures that any change to the vendors recommendations are documented and provide an equivalent level of protection during storage.

SUMMARY

This plant modification changed piping configurations to allow removal of excess condensate from the condenser hotwell by both the condensate booster pump and the condensate pump discharge to the Condensate-Storage Tank (CST). As previously designed, only the condensate pump discharge was utilized for this function.

SAFETY

SUMMARY

This modification allows improved chemistry control. This modification deals with the non-safety portion of the condensate and chamical feed system. This modification does not change the elevation of any penetrations in the CST. The change does not increase the probability or consequences of analyzed accidents, nor introduce a different type of accident or equipment malfunction than already evaluated in the FSAR.

Thus no unreviewed safety question exists.

o CHANGE TO PROCEDURE AS DESCRIBED IN THE FSAR TITLE: OP-125, Rev. 1, Advance Change 1/3, Post Accident Hydrogen System Approval Date:

February 12, 1987 FUNCTIONAL

SUMMARY

OP-125 utilizes containment isolation valves for the hydrogen analyzers for continuous sampling, therefore, causing the valves to be normally open. FSAR Table 6.2.4-1 indicated that these valves were normally closed instead of normally open.

SAFETY

SUMMARY

By operating the system continuously, the system is available for monitoring minimizing time needed to start the system. This procedure change does not increase the probability or consequences of analyzed accidents, nor introduce a different type of accident or equipment malfunction than already evaluated in the FSAR. Thus no unreviewed safety question exists.

CHANGE TO PROCEDURE AS DESCRIBED IN THE FSAR TITLE:

Semi-Fixed Foam System FUNCTIONAL

SUMMARY

This procedural change revises Fire Protection procedures for the semi-fixed foam system for the auxiliary boiler fuel oli storage tanks located in the yard. After the foam solution is depleted, water will be manually shut off to prevent diluting the foam blanket instead of the previous Fire Protection practice of allowing the water to centinue to flow.

SAFETY

SUMMARY

This procedural change has no safety impact since this foam system is not used to protect safety related systems or areas. The procedural change actually improves the fire protection provided to the auxiliary boiler fuel oil storage tanks and as such does not decrease the margin of safety.

This change does not affect the Fire Protection Safe Shutdown Analysis.

CHANGE TO PROCEDURE AS DESCRIBED IN THE FSAR TITLE: Control of Safety Related Monitors from the Non-Safety RM-Il Consoles FUNCTIONAL

SUMMARY

This procedure revision allows control of data base changes for safety related monitors from the non-safety related RM-ll Consoles.

Previously, control of data base changes for safety related monitors was only possible from the safety related RM-23 monitors in the Control Room. The RM-ll control capability will allow Radiation Control personnel to respond expeditiously and avoid major system problems.

SAFETY

SUMMARY

This procedure revision is an administrative change in the control of radiation monitoring equipment.

It does not increase the probability or consequences of an analyzed accident, nor does it create the possibility of a new of different type of accident. This revision does not change the operation of any plant system.

It only changes the location of control of portions of the Radiation Monitoring System that were previously controlled from the RM-23.
