SUMMARY

A.

Design Change Packages 2EC-3202 Pkg 1 2EC-3081 Pkg 1 "CW-0008 circulating Water Electrical Upgrade Unit 2 (Outage)" - This DCP performs the following work:

1.) This DCP completes the electrical tie-in of the new Unit 2 Circ. Water 460V substation and demolished the existing substation.

The substation was installed previously on its foundation by DCP lSC-2298.

A new splice/pull box is installed on the existing foundation to perform the cable splices.

The substation is tested and re-energized; 2.) The 230 VAC motor control center, transformer, control equipment and lighting panels are located in a metal building ("Control House").

This control house is dismantled and replaced.

All existing electrical equipment is reused.

New ventilation, sump pump and piping is provided for the cable manhole; 3.) This DCP refurbished panels 360-2 and TS-2.

Panels 670-2A, 670-2B and 670-2C are replaced, and 4.)

Three of the four screen wash pump motors (No. 21, 23, 24) have been replaced over time as the old motors failed.

When the motors were replaced, they were upgraded from 125 horsepower to 150 horsepower.

The remaining 125 HP motor (No. 22) is replaced by this DCP.

Cabling to all four screen wash pumps is replaced to accommodate the increased motor size.

This DCP does not reduce the margin of safety as defined in the basis for any Technical Specification.

There are no requirements directly specified for the operation or performance of any circulating water system equipment in the Technical Specifications.

This modification increases the circulating water system reliability and availability.

"Penetration Area Welding Receptacles" Rev. 1 - This DCP provides three new 460V welding receptacles, one in the Chilled Water Pump Area, El. 100, at column lines BC-16.2, one in the Main Steam Penetration

SUMMARY

50-311 SALEM 2 DECEMBER 10, 1993 R. HELLER (609)339-5162 Area, El. 100, near column lines FF-16.8, and one in Personnel Hatch Area, 'El. 100, near column lines GG-16.8.

These receptacles are in a common circuit fed from a new circuit breaker, I2118-21X, in the 2El 460-230 Volt Control Center.

With this installation, welding receptacles will be available to power welding machines in these areas with no need to breach wall penetrations for power cables.

This will provide the capability for TIG welding, as well as SMAW welding, in each of these areas without the need to breach wall penetrations.

This DCP will not reduce the margin of safety as defined in the basis for any Technical Specification because the new welding machine receptacles will be on a circuit powered from a non-vital bus, the 2EL 460-230V Control Center.

The control center has the spare capacity to take the additional circuit and there will be no effect on any other part of the power distribution system, vital or non-vital.

There is no increase in load on the control center or the group bus as far as the Load Management Study is _

concerned because the welding receptacles are intermittent loads.

Activities pertaining to the affected penetrations will be conducted in accordance with approved procedures.

Safety Evaluations (S/E)

CN 93-24 "SGS-UFSAR Section 3.6.5.12.5 Revisions" -

DEF

1. DES-93-00660 identified that SGS-UFSAR Section 3.6.5.12.5 which applies only to Unit 2 does not address moderate energy pipe failure in the 10 Ton C02 Room and the Diesel Fuel Storage Tank areas.

SGS-UFSAR Section 3.1.3 identifies that the NRC required that a Moderate -

Energy Break Analysis (MEBA) be performed for Unit 2.

The proposal revises SGS-UFSAR Section 3.6.5.12.5 to address the 10 Ton C02 room, the Diesel Fuel storage Tank areas, and the entrance to these areas on the basis of a revised MEBA (Design Calculation S-C-ZZ-SDC-1203} as follows: "The 10 Ton C02 Room, the Diesel Fuel Storage Tank areas, and the entrance to these areas contain service water, fuel oil, and carbon dioxide

SUMMARY

50-311 SALEM 2 DECEMBER 10, 1993 R. HELLER

{609)339-5162 fire protection MEL piping in addition to diesel fuel oil storage and transfer system equipment.

The areas do not contain floor drainage, hence service water or fuel oil piping failure could cause flooding of the areas and the adjoining fuel transfer pump rooms.

therefore, flooding of diesel fuel oil storage and transfer system equipment can occur.

Spray damage can also occur.

However, because blackout coincident with service water or fuel oil piping failure is not a design basis condition at Salem Generating Station, diesel fuel oil storage and transfer equipment are not required to function to mitigate the consequences of such piping failure.

Protection against the effects of service water or fuel oil piping failure is not required for diesel fuel oil storage and transfer system equipment.

No changes are being made to any component, system or structure.

There is no effect on plant operation.

The only change is the addition of a description of the facility in SGS-UFSAR Section 3.6.5.12.5, which is changed on the basis o'f a revised MEBA {Design Calculation S-C-ZZ-SDC-1203).

There is no reduction in the margin of safety as defined in the basis for any Technical Specification.

SALEM UNIT NO. 2 SALEM GENERATING STATION MONTHLY OPERATING

SUMMARY

UNIT 2 NOVEMBER 1993 The Unit began the period operating at full power and continued to operate at essentially full power until November 14, 1993, when load was reduced to 50% for repairs to repair #21 steam generator feed pump.

The Unit was restored to full power on November 15, 1993, and continued to operate at that level until November 23, 1993, when power was reduced to 79% due to jamming of the travelling screen for 23A circulator.

The repairs were completed and a power escalation commenced later the same day.

Power was held at 86% due to governor swings on #21 steam generator feed pump.

Power was increased to 100%

on November 26, 1993.

A load reduction to 80% was required on November 29, 1993 due to forced cooling problems on the main transformer.

The cooling was restored and power increased to 100%

later in the day.

The Unit continued to operate at 100% power through the remainder of the period.
