PILGRIM NUCLEAR POWER STATION DOCKET NO. 50-293

1.0 INTRODUCTION

By letter dated January 4, 2007, (Reference 1), Entergy Nuclear Operations, Inc. (the licensee) submitted a request for changes to the Technical Specifications (TSs) for Pilgrim Nuclear Power Station (PNPS). The proposed changes revise TS that involve Limiting Conditions for Operation (LCOs) and Surveillance Requirements (SR) applicable to Control Rod Operability in TS 3/4.3.B; Scram Insertion Times in TS 3/4.3.C; and Control Rod Accumulators in TS 3/4.3.D. The primary purpose of the proposed change is to revise TS 3/4.3.C to change the required control rod scram time test frequency interval from "within each 120 days of operation at-power" to "within each 200 days of cumulative operation in RUN." This change is consistent with Consolidated Line Item Improvement Process (CLIIP) Notice of Availability, dated August 23, 2004 (69 FR 51864) and Technical Specification Task Force change traveler TSTF-460, Rev. 0. The secondary purpose of the proposed change is to revise TS 3/4.3.B, TS 3/4.3.C, and TS 3/4.3.D to ensure consistency with NUREG-1433, Revision 3, "Standard Technical Specifications (STS),

General Electric Plant, BWR/4," specifications 3.1.3, 3.1.4, and 3.1.5. The STS format changes involve adoption of a revised control rod scram time test methodology. The proposed scram time test criterion (TS 3/4.3.C) evaluates control rod operability based on capability of individual control rods to meet established scram times. The existing TS requirements for averaging all operable control rod scram times and for grouped array averaging of multiple control rod scram times are removed. The proposed scram time test criterion establishes a new category of operable but "slow" control rods and establishes allowable limits for the number and distribution of these "slow" rods.

2.0 REGULATORY EVALUATION

The TS governing the control rod scram time surveillance is intended to assure proper function of control rod insertion. Following each refueling outage, all control rod scram times are verified.

In addition, periodically during power operation, a representative sample of control rods is selected to be inserted to verify the insertion speed.

2 A representative sample is defined as a sample containing at least 10 percent of the total number of control rods. The current TS stipulates that no more than 20 percent of the control rods in this representative sample can be slow during the post outage testing. With more than 20 percent of the sample declared to be slow per the criteria in Table 3.1.4-1, additional control rods are tested until this 20 percent criterion (e.g., 20 percent of the entire sample size) is satisfied, or until the total number of slow control rods (throughout the core, from all surveillances) exceeds the LCO limit. For planned testing, the control rods selected for the sample should be different for each test. The acceptance criterion for at-power surveillance testing has been redefined from 20 percent to 7.5 percent. This tightened acceptance criterion for at-power surveillance aligns with the TS 3.1.4 requirement for the total control rods allowed to have scram times exceeding the specified limit.

The control rod scram accumulators are part of the control rod drive (CRD) system and are provided to ensure that the control rods scram under varying reactor conditions. The control rod scram accumulators store sufficient energy to fully insert a control rod at any reactor vessel pressure. The design-basis accident (DBA) and transient analyses assume that all of the control rods scram at a specified insertion rate. Operability of each individual control rod scram accumulator helps ensure that the scram reactivity assumed in the DBA and transient analyses can be met. The existence of an inoperable accumulator may invalidate prior scram time measurements for the associated control rod. The actions being revised address the options for declaring control rods associated with inoperable accumulators as either slow or inoperable.

3.0 TECHNICAL EVALUATION

The license amendment request (LAR) proposes changes to the PNPS TSs in three main areas, 1) Control Rod Operability as described in TS LCO Section 3.3.B and TS SR Section 4.3.B, 2) Scram Insertion Times as described in TS LCO Section 3.3.C and TS SR Section 4.3.C, and 3) Control Rod Accumulators as described in TS LCO Section 3.3.D and SR Section 4.3.D.

Its primary purpose is to revise TS SR 4.3.C to change the required control rod scram time testing frequency interval from Awithin each 120 days of operation at-power@ to Awithin each 200 days of cumulative operation in RUN.@ This change is consistent with TSTF-460, Rev. 0 (Reference 3).

Its secondary purpose is to revise the other LCOs and SRs in TS 3.3 and 4.3 to be consistent with NUREG-1433, Rev. 3, AStandard Technical Specifications (STS), General Electric Plant, BWR/4@ (Reference 2).

Each change is discussed and evaluated below.

3.1 TS LCO 3.3.B.1 Action A.1 The proposed change revises the action statement to require operators to Averify stuck control rod separation criteria are met immediately.@ This change to reference the stuck control rod separation criteria, newly defined in the TS Bases 3/4.3.B.1 Actions A.1, A.2, A.3, and A.4, is needed with the introduction of a new control rod operability criterion which defines Aslow@ but operable control rods and the corresponding stuck rod separation criteria now based on Aslow@

but operable control rods. This change is consistent with STS Bases 3.1.3 and the new stuck

3 rod separation criteria will continue to meet the local scram reactivity rate assumptions in the licensing basis analysis. In addition, the Nuclear Regulatory Commission (NRC) staff concludes that the new control rod operability criterion is acceptable, as evaluated in Section 3.3 of this safety evaluation (SE). Therefore, the NRC staff finds the proposed change to TS LCO Section 3.3.B.1 Action A.1 and associated stuck rod separation criteria acceptable.

3.2 TS SR 4.3.B.1.4 The proposed change revises the SR section to identify the additional surveillance tests based on the new TS SR 4.3.C. The NRC staff finds the new TS SR 4.3.C acceptable, as discussed in Sections 3.4 and 3.5 of this SE. Therefore, the NRC staff finds the proposed change to TS SR Section 4.3.B.1.4 acceptable.

3.3 TS LCO 3.3.C The proposed change revises the current TS LCO 3.3.C.1 and TS LCO 3.3.C.2 to identify a new scram time acceptance criteria which allows a condition where a control rod may be considered Aslow@ but still operable.

The proposed change adopts a different testing method to determine if the measured scram insertion times are sufficient to provide sufficient negative reactivity assumed in the licensing basis analysis. The LAR references BWROG-8754, dated September 1987 (Reference 4) as the bases for the proposed TS LCO 3.3.C approach. The current LCO requires two sets of scram insertion time tables, one identifying the average scram insertion times for all operable control rods and one identifying the average scram insertion times for the three fastest operable control rods in all two by two arrays. The proposal simplifies the approach by introducing one scram insertion time table which identifies any control rod not within the specified scram insertion times as Aslow.@ This change to base the scram time acceptability on individual control rod performance also eliminates the concern of potentially allowing operation with too many Aslow@ rods because a few fast scramming rods were available to provide an acceptable Aaverage time@ of multiple rods. Furthermore, it identifies any control rod with scram times > 7 seconds to notch position 04 as inoperable. The revised LCO would allow no more than 10 control rods (or 7 percent of 145) to be Aslow@ and allows no more than two operable but Aslow@ control rods to occupy adjacent locations. The proposed scram insertion time table also identifies the tests that should be performed on fully withdrawn rods and defines the criteria based on reactor steam dome pressure.

The purpose of TS LCO 3.3.C is to ensure that the negative scram reactivity assumptions in the licensing basis analysis are supported by the actual scram performance of the individual control rods. The methodology used in the licensing basis analysis assumes all control rods scram at the same speed (i.e., the analytical scram time). The licensing basis analysis that is performed on a cycle specific basis will assume the TS scram time limits. Therefore, if all control rods scram at least as fast as the proposed TS time limits, then the analytical scram reactivity curve will be met. It is recognized that for a situation where individual control rods do not satisfy the time limits, the condition may be acceptable if the resulting scram reactivity still meets or exceeds the analytical scram reactivity curve where slower control rods are compensated by faster control rods. The analysis discussed in Reference 3 provides that the

4 analytical scram reactivity curve will be satisfied if no more than 7 percent of the rods are slow and these slow rods are distributed in satisfactory manner. Reference 3 has been previously reviewed and approved by the NRC staff and has been incorporated into the STS. It is the current control rod operability basis for many of the operating boiling-water reactors.

Based on above, there is reasonable assurance that applying the revised TS LCO 3.3.C approach to PNPS will not adversely impact its ability to remain within the licensing basis analysis envelope. Therefore, the NRC staff finds the proposed change to TS LCO 3.3.C acceptable.

3.4 TS SR 4.3.C.1 The proposed change replaces the current TS SR 4.3.C.1 with three SRs (TS SR 4.3.C.1, TS SR 4.3.C.3, and TS SR 4.3.C.4) consistent with STS 3.1.4. The three SRs will continue to address the current TS SR 4.3.C.1 requirement of scram testing the operable rods prior to exceeding 40 percent rated thermal power following a refueling outage or an extended outage greater than 120 days. The change separates the current SR into two SRs, creating one SR to be performed following an extended outage and another SR to be performed following a normal refueling outage. The change also imposes an additional SR to perform scram testing on rods affected by control rod or CRD system work prior to declaring the rod(s) operable.

Relative to the current TS, more conservative provisions are included in the revision to perform scram testing with CRD pumps isolated and reactor pressure greater than or equal to 800 psig. Having the CRD pump isolated ensures that associated pump head will not influence the scram testing. The proposed change to revise reactor pressure requirement from > 950 psig to $ 800 psig is more conservative because the maximum scram times occur at reactor pressure of approximately 800 psig. The proposed changes will continue to satisfy the current requirements and provide additional conservatism. Therefore, the NRC staff finds the proposed change to TS SR 4.3.C.1 acceptable.

3.5 TS SR 4.3.C.2 The proposed change revises the current TS SR 4.3.C.2 to extend the at-power scram time test frequency from Awithin 120 days of operation@ to Awithin each 200 days of cumulative operation in RUN.@

The existing TS SR 4.3.C.2 requires that scram testing be performed on 10 percent of the CRDs within each 120 days of operation. The frequency of 120 days is proposed to be changed to 200 days based on industry experience demonstrating that scram times do not significantly change over an operating cycle. The licensee evaluated the historical performance of the PNPS CRD scram times over the past five cycles. The data showed that out of 1890 individual CRD scram time tests, there were no instances of inoperable control rods (i.e. > 7 sec) and only six instances where an individual CRD did not meet the revised scram time (i.e., the CRD would be considered Aslow@). The NRC staff concurs that the historical data justifies the reliability of scram capability. In addition, this change, which is addressed in TSTF-460, Rev. 0 (Reference 3), has been previously reviewed and approved by the NRC staff and has been incorporated into the STS. Many of the current operating boiling-water reactors operate under this approach. The NRC staff finds the proposed change to TS SR 4.3.C.2 acceptable.

5 3.6 TS SR 4.3.D The current TS SR 4.3.D does not identify an explicit criterion for accumulator operability.

The proposed change revises the current TS SR 4.3.D to explicitly define the accumulator operability criterion based on a minimum of 940 psig accumulator pressure. This value is based on the equipment specification and testing data. The proposed change also defines the surveillance frequency as every 7 days. This is consistent with STS 3.1.5. The NRC staff finds the proposed change to TS SR 4.3.D acceptable.

3.7 TS LCO 3.3.D Actions A, B, C, D, and E The proposed TS LCO 3.3.D Action A addresses the condition where one control rod accumulator is inoperable when the reactor pressure is $ 950 psig. It is important to note that at reactor pressures $ 950 psig, the control rod will scram even without the accumulator available, albeit not with the required scram times. The proposed change revises the current TS LCO 3.3.D Action A to provide an option to declare a control rod with inoperable accumulator, Aslow@ within 8 hours9.259259e-5 days <br />0.00222 hours <br />1.322751e-5 weeks <br />3.044e-6 months <br />. The 8-hour completion time is viewed as reasonable based on availability of large number of control rods to provide the scram function. The ability to declare Aslow@ rods is allowed only for control rods not previously know to be Aslow,@ since additional degradation by an inoperable accumulator must be prevented for an already Aslow@

rod. This change is consistent with STS 3.1.5. The NRC staff finds the proposed change to TS LCO 3.3.D Action A acceptable.

TS LCO 3.3.D Action B is deleted. The purpose of the current TS LCO 3.3.D Action B is to address the condition where reactor pressure is < 950 psig. This condition is now addressed in the revised TS LCO 3.3.D Action C. This change is consistent with STS 3.1.5. The NRC staff finds the proposed deletion of TS LCO 3.3.D Action B acceptable.

The proposed TS LCO 3.3.D Action B now addresses the condition where two or more control rod accumulators are inoperable when the reactor pressure is $ 950 psig. The same option to allow control rods to be declared Aslow@ is provided as the proposed TS LCO 3.3.D Action A, but the required completion time is reduced to 1 hour1.157407e-5 days <br />2.777778e-4 hours <br />1.653439e-6 weeks <br />3.805e-7 months <br />. This completion time is reasonable based on the ability of the reactor pressure to scram the rods and the anticipated low probability of a DBA or transient occurring while the affected accumulator is inoperable.

The proposed change also ensures that the current TS LCO 3.3.D Action C.1 requirement continues to be satisfied by requiring the restoration of charging water header pressure to $

940 psig be attempted within 20 minutes. This change is consistent with STS 3.1.5. The NRC staff finds the proposed TS LCO 3.3.D Action B acceptable.

The proposed TS LCO 3.3.D Action C addresses the condition where additional accumulators may become unavailable due to loss of charging water header pressure coincident with reactor dome pressure < 950 psig. The operators are instructed to fully insert all associated control rods and declare the associated rod inoperable. There is no technical change relative to the current TS associated with proposed TS LCO 3.3.D Action C. This change is consistent with STS 3.1.5. The NRC staff finds this change acceptable.

The proposed change to TS LCO 3.3.D Action D (which was Action E) is editorial to ensure that the action statements are correctly referenced. The NRC staff finds this change acceptable.

4.0 STATE CONSULTATION

In accordance with the Commission's regulations, the Massachusetts State official was notified of the proposed issuance of the amendment. The State official had no comments.

5.0 ENVIRONMENTAL CONSIDERATION

The amendment changes a requirement with respect to installation or use of a facility component located within the restricted area as defined in 10 CFR Part 20 and changes surveillance requirements. The NRC staff has determined that the amendment involves no significant increase in the amounts, and no significant change in the types, of any effluents that may be released offsite, and that there is no significant increase in individual or cumulative occupational radiation exposure. The Commission has previously issued a proposed finding that the amendment involves no significant hazards consideration, and there has been no public comment on such finding (72 FR 20381). Accordingly, the amendment meets the eligibility criteria for categorical exclusion set forth in 10 CFR 51.22(c)(9). Pursuant to 10 CFR 51.22(b), no environmental impact statement or environmental assessment need be prepared in connection with the issuance of the amendment.

6.0 CONCLUSION

The Commission has concluded, based on the considerations discussed above, that: (1) there is reasonable assurance that the health and safety of the public will not be endangered by operation in the proposed manner, (2) such activities will be conducted in compliance with the Commission's regulations, and (3) the issuance of the amendment will not be inimical to the common defense and security or to the health and safety of the public.
