ATTACHMENT 1 LCR H04-07 LR-N04-0454 HOPE CREEK GENERATING STATION FACILITY OPERATING LICENSE NO. NPF-57 DOCKET NO. 50-354 DESCRIPTION AND ASSESSMENT

1.0 DESCRIPTION

The proposed changes would revise the required actions within Hope Creek Generating Station Technical Specification (TS) 3.1.3.1, "Control Rod Operability,"

for the condition of having one or more scram discharge volume vent or drain lines with valve(s) inoperable. The changes are based on Technical Specification Task Force (TSTF) change traveler TSTF-404 (Revision 0) that has been approved generically for the BWR (boiling water reactor)/4 Standard Technical Specifications (STS), NUREG-1433, Revision 2.1 The availability of this TS improvement was announced in the Federal Register on February 24, 2003, as part of the consolidated line item improvement process (CLIIP).

2.0 ASSESSMENT 2.1 Anplicability of Published Safety Evaluation PSEG Nuclear, LLC (PSEG) has reviewed the safety evaluation published on February 24, 2003, (68 FR 8637) as part of the CLIIP. This verification included a review of the NRC staff's evaluation as well as the supporting information provided to support TSTF-404. PSEG has concluded that the justifications presented in the TSTF proposal and the safety evaluation prepared by the NRC staff are applicable to Hope Creek Generating Station and justify this amendment for the incorporation of the changes to the Hope Creek Generating Station TS.

2.2 Optional Changes and Variations PSEG is not proposing any variations or deviations from the TS changes described in TSTF-404 or the NRC staffs model safety evaluation published on February 24, 2003.

1 Hope Creek Generating Station has not adopted Standard Technical Specifications (STS);

therefore, the requirements of STS 3.1.8, "Scram Discharge Volume (SDV) Vent and Drain Valves,' referenced inTSTF-404, are actually addressed by Hope Creek Generating Station TS 3.1.3.1. Regulatory Issue Summary 2000-06, 'CLIIP for Adopting STS Changes for Power Reactors", permits adoption of CLIIP changes for Licensees that have not converted to STS, but have determined that the TSTF isapplicable to their facility.

Technical Specification Page Bases 3/4.1.3 B 3/4 1-2a

REACTIVITY CONTROL SYSTEMS CONTROL RODS (Continued)

The control rod system is designed to bring the reactor subcritical at a rate fast enough to prevent the MCPR from becoming less than the fuel cladding Safety Limit during the limiting power transient analyzed in Section 15.4 of the FSAR. This analysis shows that the negative reactivity rates resulting from the scram with the average response of all the drives as given in the specifications, provide the required protection and MCPR remains greater than the fuel cladding Safety Limit. The occurrence of scram times longer than those specified should be viewed as an indication of a systematic problem with the rod drives and therefore the surveillance interval is reduced in order to prevent operation of the reactor for long periods of time with a potentially serious problem. S The scram discharge volume is required to be OPERABLE so that it will be available when needed to accept discharge water from the control rods during a reactor scram and will isolate the reactor coolant system from the containment when required.

ons7et+l hkeel Control rods with inoperable accumulators are declared inoperable and Specification 3.1.3.1 then applies. This prevents a pattern of inoperable accumulators that would result in less reactivity insertion on a scram than has been analyzed. The OPERABILITY of the control rod scram accumulators is required to ensure that adequate scram insertion capability exists when needed over the entire range of reactor pressures. The OPERABILITY of the scram accumulators is based on maintaining adequate accumulator pressure.

In OPCON 1 and 2, the scram function is required for mitigation of DBAs and transients, and therefore the scram accumulators must be OPERABLE to support the scram function. In OPCON 3 and 4, control rods are only allowed to be withdrawn under limits imposed by the reactor mode switch being in shutdown and by the control rod block being applied. This provides adequate requirements for control rod scram accumulator OPERABILITY during these conditions. In OPCON 5, withdrawn control rods are required to have OPERABLE accumulators.

The actions of Specification 3.1.3.5 are modified by a note in:icating that a separate Condition entry is allowed for each control rod scram accumulator. This is acceptable since the required Actions for each Condition provide appropriate compensatory actions for each affected accumulator.

Complying with the Required Actions may allow for continued operation and subsequent affected accumulators-governed by subsequent Condition entry and application of associated Required Actions.

With two or more control rod scram accumulators inoperable and reactor pressure > 900 psig, adequate pressure ..:ust be supplied to the charging water header. With inadequate charging water pressure, the accumulators could HOPE CREEK B 3/4 1-2a Amendment No. 98 l

Insert 1 When one SDV vent or drain valve is inoperable in one or more lines, the associated line must be isolated to contain the reactor coolant during a scram. The 7 day allowed outage time is reasonable, given the level of redundancy in the lines and the low probability of a scram occurring while the valve(s) are inoperable and the line is not isolated. The SDV is still isolable since the redundant valve in the affected line is OPERABLE. During these periods, the single failure criterion may not be preserved, and a higher risk exists to allow reactor water out of the primary system during a scram.

If both valves in a line are inoperable, the line must be isolated to contain the reactor coolant during a scram. The 8 hour9.259259e-5 days <br />0.00222 hours <br />1.322751e-5 weeks <br />3.044e-6 months <br /> allowed outage time to isolate the line is based on the low probability of a scram occurring while the line is not isolated and unlikelihood of significant CRD seal leakage.

Note *** indicates that separate Action entry is allowed for each SDV vent and drain line. This is acceptable, since the Required Actions for each Condition provide appropriate compensatory actions for each inoperable SDV line. Complying with the Required Actions may allow for continued operation, and subsequent inoperable SDV lines are governed by subsequent entry and application of associated Required Actions.

Note **** indicates that when a line is isolated, the potential for an inadvertent scram due to high SDV level is increased. During these periods, the line may be unisolated under administrative control. This allows any accumulated water in the line to be drained, to preclude a reactor scram on SDV high level. This is acceptable since the administrative controls ensure the valve can be closed quickly, by a dedicated operator, if a scram occurs with the valve open.
