50-272 SALEM 1 JUNE 10, 1991 J. FEST (609)339-2904 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 these evaluations and agrees with their conclusions that these items do not present Unreviewed Safety Questions (USQs). ITEM A. Design Change Packages lEC-3089 Pkgs. 2 & 4 lEC-3065 Pkg. 1

SUMMARY

"Reactor Coolant Pump Oil Lift Pump & Motor Assembly Enclosure Modifications" -Package 2 proposes the modification of the existing No. 12 RCP oil lift pump & motor assembly enclosure to close up some gaps that exist in the enclosure.

This will ensure the oil lift pump motor is completely isolated from the enclosure.

Additional mounting bolt holes will be drilled into the RCP motor flange to adequately support the modified enclosure.

There is no change in either the RCP system operation or testing procedure.

Package 4 proposes the modification of the existing No. 14 RCP oil lift pump & motor assembly enclosure to accommodate the new larger frame size RCP oil lift pump motor. This modification is restricted to structural changes involving the re-design of the left panel of the motor & pump enclosure to clear the rear of the new TEFC motor. Additional mounting bolt holes will be drilled into the RCP motor flange to adequately support the modified enclosure.

There is no change in either the RCP system operation or testing procedure. (SORC 91-034) "Narrow Range RTD Conax Connections" -As a result of this design change, the connections between the Conax connectors and the Narrow Range RTDs will be made by butt slicing the leads together, and then soldering the butt spliced connections with a high temperature solder. Shrink tubing will be placed over the soldered joints to protect against possible shorting, and the terminal posts inside the RTD heads will be removed. All special considerations associated with the use of high temperature solder have been incorporated into the DCP. The proposed modifications meet the requirements of the original design specifications.

SUMMARY

50-272 SALEM 1 JUNE 10, 1991 J. FEST (609)339-2904 "Salem Unit 1 Cycle 10 Final Loading Pattern (Redesigned)

Reload Safety Evaluation (RSE) and NRC Notification" -This revised RSE presents a re-evaluation for Salem Unit 1, Cycle 10, which demonstrates that the conditions described in Section 1.3 for the core reload will not adversely affect the safety of the plant. This evaluation was accomplished using the described in WCAP-9273-NP-A, "Westinghouse Reload Safety Methodology".

The Salem Unit 1 Cycle 10 design has been re-evaluated due to a revised core loading pattern, caused by damage to two Region llA, one Region SB and one region 5A fuel assemblies (observed at the Cycle 9/10 refueling) . The damaged assemblies are being replaced by three Region 10 and one Region 6 fuel assemblies.

In addition, some fuel assembly shuffles were performed to enhance the overall power distribution.

This re-evaluation assures that all core design and safety limits are satisfied with the actual Cycle 9 burnup of 16520 MWD/MTU and the revised Cycle 10 loading pattern. All accident analyses have been reviewed and found to be satisfactory.

The current FSAR is still applicable to the redesigned core as the core meets the requirements of the Chapter 15 bounding analysis. (SORC 91-032)

SUMMARY

50-272 SALEM 1 JUNE 10, 1991 J. FEST (609)339-2904 "1Rl3A and 1Rl3B Warning and Alarm Setpoints" -The purpose of this design change is to implement the new Warning and Alarm setpoints for 1Rl3A and 1Rl3B Containment Cooler Radiation Monitors.

Previously it had been noted there was a difference in the implemented setpoints for the 1R13A and 1R13B radiation monitors.

This DCP will modify the setpoints to common setpoints.

The differences in the setpoints resulted from a slight change in the calculation methodology.

The original setpoints were verified to be conservative. (SORC 91-047) B. Deficiency Reports (DRs) Use-As-Is Dispositions DR # SMT 91-190A DR # ISI-91-271 "11 Steam Generator" -The tube located at Row 1 column 2 is ruptured.

the indication is approximately 1 3/8" long. The rupture is located at the area where the tube lane blocking device was previously located. This tube is plugged with explosive plugs. The existing explosive plugs in the tube do not show any evidence of leakage. (SORC 91-033) "14 Steam Generator" -Fosar examination of the secondary side of 14 S/G revealed 1 piece of thin wire, less than 1/16" diameter, length unknown, located at column 86 row 28. Fosar attempted to remove the wire but could not. The wire is stuck in the tube bundle. The resolution of this DR states the thin wire in 14 SIG may be left in place until the lRlO outage, provided the following activities are performed:

1) The tubes in contact with the identified object are eddy current tested during the lRlO outage in order to determine tube integrity and wear rate, and 2) A follow up work order is initiated to attempt removal of the wire during the lRlO outage. If the wire cannot be removed at that time, an additional disposition will be required.

Westinghouse had previously performed a similar evaluation for Salem Unit 2 which showed a Use-As-Is disposition to be acceptable.

That case involved a similar size wire. As in the case of Unit 2, the wire in 14 S/G cannot currently be retrieved.

The only potential problem is a possible tube failure caused by wear. However, the most recent eddy current examinations of the affected tubes indicate no wear has occurred. (SORC 91-049) lOCFRS0.59 EVALUATIONS MONTH: -MAY 1991 (Cont'd) ITEM c. Procedures and Revisions Sl.OP-PT-SW-0017(Q)

SUMMARY

50-272 SALEM 1 . JUNE 10 , 19 91 J. FEST (609)339-2904 "No. 12 Component Cooling Heat Exchanger Heat Transfer Performance Data Collection", Rev. 0 -This procedure provides instruction necessary to collect heat transfer data for No. 12 Component Cooling Heat Exchanger.

The data collected shall be used in a performance evaluation to meet the intent of NRC Generic Letter. 89-13. All temporary instruments will be removed at the completion of this test and the permanent instruments that were removed will be reinstalled. (SORC 91-047) "Artificial Island Security Training & Qualification Plan", Rev. 2 -This revision to the procedure is primarily to comply with New Jersey state law N.J.S.A. 2C:39-6J regarding firearms qualification and requalification for law enforcement and private security personnel.

This revision brings the procedure requirements in line with police requirements. (SORC 91-047) "Steam Generator Tube Explosive Plug Safety Evaluation", Rev. 1 -This evaluation is written to assess the* safety impact of plant operation of Salem Unit 1 with explosive plugs being returned to service. The structural adequacy of f ishmouthed tubes RlC2 and RlC3 of Steam Generator 14 during future operation, the potential bulging and fishmouthing of other explosively plugged tubes, and the probability and consequences of potential primary to secondary leakage from an explosively plugged tube for all plant conditions, are evaluated.

The effect of localized degradation on plugged tube burst capability is also assessed.

This evaluation is limited in scope to tubes that have been removed from service utilizing explosive plugs. The hydraulic ratcheting effect that is postulated to have caused the burst of tubes R1C2 and R1C3 has neither been observed nor is expected to occur in a tube removed from service utilizing a Westinghouse mechanically expanded plug. Leakage monitoring will be continued. (SORC 91-033)
