UNIT NAME:

50-272 SALEM 1 DATE: JULY 10, 1994 COMPLETED BY: R. HELLER TELEPHONE: (609)339-5162 The following items were evaluated in accordance with the provisions of the Code of Federal Regulations 10CFR50.59. The Station Operations Review Committee has reviewed and concurs with these evaluations.

ITEM

SUMMARY

A. Design Change Packages 5EC-3033 Pkg 1 "Nuclear Services Building" - This DCP provides utility tie ins for the Nuclear Services Building being constructed as a "commercial building" in the yard area between Salem and Hope Creek Generating Stations. The building will provide additional office space and equipment storage and lab facilities. This DCP addresses engineering and design issues associated with utility tie ins to plant systems, including domestic water, sanitary sewer, fire protection water, fire alarm, electric power, paging, and telecommunications, as they relate to Hope Creek and Salem plant structures, systems and components. The modified systems are not discussed in any Technical Specification and do not interface with any safety related equipment. Therefore, the margin of safety is not reduced. (SORC 94-049) lEC-3278 Pkg 1 "Fuel Handling Area Ventilation Modifications" Rev. 2 - This DCP entails modifications to the Unit 1 Fuel Handling Area Ventilation System which are summarized as follows: 1.) Replace backdraft dampers 2.) Remove the inlet guide vane controls for the non safety related dampers. The vanes themselves will be retained for use in airflow balancing and will be fixed in place after balancing 3.) Replacement of the safety related exhaust fan's inlet guide vanes and pneumatic operators as well as controls. 4.) Removal of the non safety related truck bay wall mounted exhaust fan, wiring and controls. In it's place, install a non safety related, seismically supported fixed louvre and a safety related gravity pressure relief damper which will allow outdoor makeup air to enter the building when the supply fan is off or when building negative pressure exceeds the building 2" pressure control band. However, at no

SUMMARY

time will airflow exit the building through this opening. These modifications will not reduce the margin of safety as defined in the basis for any Technical Specification. (SORC 94-050) lEC-1019 Pkg 1 "Abandonment Of No. 12 CVCS Hold-Up Tank" - The No. 12 CVCS Hold-Up Tank experienced buckling in 1979 as the result of a partial vacuum condition.

These are three eves Hold-Up Tanks for each of the two Salem units. Vacuum breakers were subsequently installed on all of these tanks. The Design Analysis which forms part of this DCP has determined the acceptability of the abandonment in place of the No. 12 CVCS Hold-Up Tank. DCP lEA-1019 formally documents abandonment of the tank. Upon implementation of this DCP, TRIS will be revised such that the normal position of the associated valves will all be "Locked Closed".

The existing level indication equipment will remain connected and active so that if liquid does seep past any of the boundary valves, alarm notification will be available at the No. 109 Panel. The abandonment of 12 eves Hold Up Tank does not reduce the margin of safety as defined in the basis for any Technical Specification.

( SORC 94-051) lEC-3320 Pkg 1 "Condensate & Feedwater Systems Overpressurization Protection Installation" - The purpose of this change is as follows: 1.) To install 3/4" x 1 11 flanged safety relief valves (11 & 12BF82) on the valve bonnet of check valves 11 and 12BF2. This will involve drilling the flat plate valve bonnets and welding on a flanged pipet connection to mount the relief valves. Route the 1 11 relief valve outlet piping from relief valves 11 & 12BF82 (Elv.

114'-0") to Columns HJ-13 and G-11 respectively, then down to Elv. 100 1 -6 11

• six (6) pipe supports will be required for these piping runs; and 2.) To install 3/4 11 x 1" flanges safety relief valves (11, 12 & 13CN141 & 142) on the 18 11 90 degree elbows on the outlet of 12/15A, B and c low

SUMMARY

pressure feedwater heaters between valves 11, 12 &

13CN24/25 and 29/30. This will involve drilling the 18 11 elbows and welding on a flanged pipet connection to mount the relief valves. The outlet piping on relief valve~ 11, 12 and 13CN141 & 142 will not require any pipe supports. These modifications address concerns identified in INPO Operations and Maintenance Reminder {O&MR-302) and INPO Significant Event Report {SER) 02-92. There is no reduction in the margin of safety as defined in the basis for any Technical Specification.

{SORC 94-051) lEA-1065 Pkg 1 "Moving of Pipe Schedule Break On Drawings" - The purpose of this change is to revise applicable plant drawings (e.g. P&IDs, Arrangement Dwgs., .... ) to move the pipe schedule breaks from the outlet of the CV-124 and CV253 valves the inlet of these valves. CV124 and CV253 act as barrier valves between safety related and non-safety related portions of the eves system.

To move the pipe schedule breaks on applicable drawings to include these valves in the safety related portions would be to conform to ANS/ANSI Standards {See N10.2a-1975/ANS-51.8 Section 2.3.3). These valves are presently being purchased as safety related/seismic class 1 (valve mark number AA-28). Also, a work history review for these valves shows that maintenance has, and continues to be, performed to safety related

/seismic class 1 standards. Shifting pipe schedule breaks to include CV124 and CV253 in safety related sections of piping will only move plant requirements in a more conservative direction. There is no reduction in the margin of safety as defined in the basis for any Technical Specification. {SORC 94-051)

SUMMARY

B. Procedures and Revisions NC.NA-AP.ZZ-0024(Q) "Radiation Protection Program" - This is a limited revision to clarify the scope of certain monitoring requirements, to incorporate recent NRC guidance concerning training and monitoring requirements, and to clarify certain administrative requirements. The changes to this procedure do not relate to design criteria, specifications or operation of the fuel cladding, RCS boundary, or containment and does not address any margin of safety as defined in the bases for the Technical Specifications. Therefore, there is no reduction in the margin of safety as defined in the basis for any Technical Specification.

(SORC 94-051)

c. Temporary Modifications TMR 93-109 "Upgrade Hoisting Capacity of the Fuel Handling Crane From 5 tons to 20 Tons" - This T-Mod is in support of DCP lEC-3252, and will install a new trolley and hoist for the removal and installation of racks. The existing trolley and hoist will be used for moving the spent fuel. This temporary modification to the fuel handling crane is to be done at the start of the rerack operation. No welding or permanent attachments are made to the crane. No existing crane components are to be removed. This modification will not reduce the margin of safety as defined in the basis for any Technical Specification. (SORC 94-049)

• SALEM GENERATING STATION MONTHLY OPERATING

SUMMARY

- UNIT 1 JUNE 1994 SALEM UNIT NO. 1 The Unit began the period shutdown for repairs to a pressurizer safety valve and replacement of an Individual Rod Position Indicating (IRPI) system step counter. The Unit entered Mode 2 "Startup" on June 2, 1994, and was synchronized on June 4, 1994. Power was increased to 100% at 02:14 on June 7, 1994, and was later reduced to 90% at 23:00 the same day to repair a heater drain pump. The repairs were completed on June 10, 1994, and power was being increased when a generator/reactor trip occurred due to a failed generator voltage regulator potential transformer. The transformer was replaced and the Unit was synchronized on June 15, 1994. The Unit achieved full power on June 17, 1994. On June 17, 1994, power was reduced to 90% to repair a heater drain tank level control problem. The repairs were completed and the Unit returned to full power on June 19, 1994. Power was briefly reduced to 84% on June 21, 1994 due to high condenser back pressure. Power was further reduced to 55% on June 23, 1994, and the Unit was taken off line on June 24, 1994, for circulating water inlet area dredging. The dredging was completed in front of Unit 1 and the Unit was synchronized on June 27, 1994. The Unit continued to operate at essentially full power throughout the remainder of the period.
