Attachment 1 W3FI -2005-0073 Analysis of Proposed Technical Specification Change

Attachment 1 to W3F11-2005-0073 Page 1 of 5

1.0 DESCRIPTION

This letter is a request to amend Operating License NPF-38 for Waterford Steam Electric Station, Unit 3 (Waterford 3). The proposed change will revise the Operating License to modify the Surveillance Requirements (SRs) associated with Waterford 3 Technical Specification (TS) 3.1.1.3, Moderator Temperature Coefficient (MTC) and will allow the use of the Startup Test Activity Reduction Program (WCAP-1601 1-P-A).

The proposed change is made, with minor differences noted below, using Technical Specification Task Force (TSTF) Improved Standard Technical Specification Change Traveler TSTF-486, Revise MTC Surveillance for Startup Test Activity Reduction (STAR) Program (WCAP-160 11), which is currently under NRC review. The Waterford 3 TSs are formatted to the Standard Technical Specifications for Combustion Engineering Pressurized Water Reactors (NUREG-0212). Therefore, the wording of the TSTF has been modified to coincide with the original standard TS format while retaining the context of the TSTF. The projected approval date of the TSTF traveler is June 2006. Revision 0 of the Topical Report (WCAP-16011-P-A, Startup Test Activity Reduction Program) was approved on January 14, 2005.

Waterford 3 requests the proposed change be approved by September 18, 2006 in order to support its fall 2006 refueling outage.

2.0 PROPOSED CHANGE

The proposed change revises Waterford 3 SR 4.1.1.3.1 and SR 4.1.1.3.2.a by adding the following note as note (3) and renumbering the existing note (3) to note (4):

For fuel cycles that meet the applicability requirements given in WCAP-1601 1-P-A, the verification prior to entering MODE 1 may be made using the predicted MTC as adjusted for the measured boron concentration.

The existing note (3), which is associated with SR 4.1.1.3.2.c, will be designated as note (4) and will be appended with the following:

For cycles that meet the applicability requirements given in WCAP-1601 1-P-A, the MTC determination of surveillance 4.1.1.3.2.c is not required if the result of the test required in surveillance 4.1.1.3.2.b is within a tolerance of +/- 0.16 x 104 AkVF from the corresponding design value.

The TS Bases will also be changed in accordance with the Waterford 3 TS Bases Control Program (TS 6.16).

In summary, a change is proposed that: 1) allows the MTC determination, which is required prior to initial operation above 5% of Rated Thermal Power after each fuel loading, to be made by using the predicted MTC as adjusted for the measured boron concentration when the applicability requirements given in WCAP-1 6011-P-A are met; and 2) allows the elimination of the end of cycle (EOC) MTC measurement when the applicability requirements given in WCAP-1 6011 -P-A are met and the result of the MTC determination performed at greater than 15% of Rated Thermal Power and prior to reaching 40 effective full power days (EFPD) is within a tolerance of +/- 0.16 x 10- Ak/k/OF from the corresponding design value.

Attachment 1 to W3F11-2005-0073 Page 2of5

3.0 BACKGROUND

The limitations on MTC are provided to ensure the assumptions used in the accident and transient analysis remain valid throughout each fuel cycle. The SRs confirm that the MTC remains within acceptable values.

Westinghouse Topical Report (TR) WCAP-1601 1-P-A, Revision 0, Startup Test Activity Reduction Program, proposed changes to reactor reload startup testing. The NRC approved TR describes a method to reduce the time required for startup testing.

4.0 TECHNICAL ANALYSIS

The TR justifies the elimination of certain startup testing requirements, including the control element assembly (CEA) worth and isothermal temperature coefficient (ITC) measurements at hot zero power (HZP). The TR also proposed to substitute the measured value of the MTC at HZP with an alternate MTC value consisting of the predicted (calculated) MTC as adjusted for the measured critical boron concentration at HZP.

STAR program applicability requirements for implementing this change are included in WCAP-1601 1-P-A. The NRC's Final Safety Evaluation (SE) for WCAP-1601 1-P-A dated January 14, 2005 includes the following conditions and limitations. Entergy's method of compliance with these is as follows:

1. The STAR program is applicable only to the participating plants as defined in Table 3-1 of the TR.

Waterford 3 was a participating plant as identified in Table 3-1 of the TR.

2. Should any of the STAR test results fall outside the test criteria, either ascertain that the safety analysis and STAR applicability requirements are satisfied, or discontinue use of the STAR program for that fuel cycle.

Entergy will include the applicability requirements in appropriate site startup testing procedures. Entergy will include guidance in the procedures to ensure that the safety analysis and STAR applicability requirements are satisfied. If the safety analysis or STAR applicability requirements are not satisfied, the STAR program for the affected fuel cycle will not be used.

3. The Staff requires each licensee using STAR to submit a summary report following the first application, either successful or not, of STAR to its plant. The report should (a) identify the core design method used, (b) compare the measured and calculated values and the differences between these values to the corresponding core design method uncertainties and (c) show compliance with the STAR applicability requirements. If the application of STAR is unsuccessful, identify the reasons why the STAR application failed.

Entergy will submit a summary report following the first application of STAR at Waterford 3 that will: (a) identify the core design method used, (b) compare the measured and calculated values and the differences between these values to the corresponding core design method uncertainties and (c) show compliance with the STAR applicability

Attachment 1 to W3Fl-2005-0073 Page 3 of 5 requirements. If the application of STAR is unsuccessful, Entergy will identify the reasons why the STAR application failed.

The following differences exist between the proposed traveler TSTF-486, which was submitted for NRC approval in June 2005, and the proposed change to the Waterford 3 TS:

  • The TSTF traveler added the following additional requirement to verify MTC is within the upper limit specified in the COLR: "Each fuel cycle within 7 effective full power days (EFPD) of reaching 40 EFPD core burnup.' The new SR proposed by the traveler is required only when the MTC determination prior to entering Mode 1 is verified using the measured boron concentration. Waterford 3 currently has a Mode 1 SR to verify MTC is within both upper and lower limits by confirmatory measurements (SR 4.1.1.3.2.b) prior to reaching 40 EFPD. No change is proposed to the existing Waterford 3 SR. Therefore, the proposed change that is reflected in the traveler is not necessary for Waterford 3.
  • The traveler did not specify the conditions and limitations included in the NRC's Final Safety Evaluation for the TR. Entergy's responses to the conditions are provided.
  • The traveler does not include the option to eliminate the EOC MTC measurement.

The proposed change also includes the option to eliminate the EOC MTC measurement when the applicability requirements given in WCAP-1601 1-P-A are met and the result of the MTC determination performed at greater than 15% of Rated Thermal Power and prior to reaching 40 EFPD is within a tolerance of +/- 0.16 x 104 Ak/k/OF from the corresponding design value.

The allowance to eliminate the EOC MTC measurement, which was approved for Waterford 3 by Amendment 159, was addressed in WCAP-1 601 1-P-A and found to be acceptable.

5.0 REGULATORY ANALYSIS

5.1 Applicable Regulatory Requirements/Criteria The proposed changes have been evaluated to determine whether applicable regulations and requirements continue to be met. Entergy has determined that the proposed changes do not require any exemptions or relief from regulatory requirements, other than the Technical Specifications, and do not affect conformance with any General Design Criterion (GDC) differently than described in the Final Safety Analysis Report (FSAR).

5.2 No Significant Hazards Consideration The proposed change will revise the Waterford Steam Electric Station, Unit 3 (Waterford 3)

Technical Specification (TS) associated with the performance of the Moderator Temperature Coefficient (MTC) verification. The proposed change will allow the MTC verification that is performed after each refueling outage and prior to initial operation above 5 percent of Rated Thermal Power to consist of the adjustment of the predicted MTC for the measured reactor coolant system (RCS) boron concentration. This will only be allowed when Startup Test Activity Reduction (STAR) program applicability requirements, which are described in WCAP-16011 -P-A, Revision 0, Startup Test Activity Reduction Program, are satisfied for the fuel cycle. The proposed change will also allow the elimination of the end of cycle (EOC) MTC measurement when the applicability requirements given in WCAP-16011-P-A are met and the

- - to W3Fl-2005-0073 Page 4 of 5 result of the MTC determination performed at greater than 15% of Rated Thermal Power and prior to reaching 40 effective full power days (EFPD) is within a tolerance of +/- 0.16 x 10-4 Ak/k/ 0F from the corresponding design value. The NRC's Safety Evaluation for WCAP-16011 -P-A is dated January 14, 2005.

Entergy Operations, Inc. has evaluated whether or not a significant hazards consideration is involved with the proposed amendment by focusing on the three standards set forth in 10 CFR 50.92, 'Issuance of amendment," as discussed below:

1. Does the proposed change involve a significant increase in the probability or consequences of an accident previously evaluated?

Response: No.

The MTC is not an initiator of any previously evaluated accidents. As an input into accident analyses, the MTC is used to predict plant behavior in the event of an accident. It was demonstrated in WCAP-16011-P-A that the modified MTC verification (i.e., measured RCS boron concentration) is adequate to ensure that the MTC remains within the limits provided the STAR applicability requirements are met. It was also demonstrated in WCAP-1 6011-P-A that the elimination of the EOC MTC measurement is acceptable when the applicability requirements given in WCAP-1 6011 -P-A are met and the result of the MTC determination performed at greater than 15% of Rated Thermal Power and prior to reaching 40 EFPD is within a tolerance of +/- 0.16 x 104 Ak/k/OF from the corresponding design value.

Therefore, the proposed change does not involve a significant increase in the probability or consequences of an accident previously evaluated.

2. Does the proposed change create the possibility of a new or different kind of accident from any accident previously evaluated?

Response: No.

The proposed change does not involve a physical alteration to the plant (i.e., no new or different type of structure, system, or component will be installed). The methods governing normal plant operations are not altered by the proposed TS change.

Therefore, the proposed change does not create the possibility of a new or different kind of accident from any previously evaluated.

3. Does the proposed change involve a significant reduction in a margin of safety?

Response: No.

The proposed change will not affect the margin of safety. The MTC limits are unaffected and an acceptable method will be used to demonstrate that MTC is within its limits.

to W3F1-2005-0073 Page 5 of 5 Therefore, the proposed change does not involve a significant reduction in a margin of safety.

Based on the above, Entergy concludes that the proposed amendment presents no significant hazards consideration under the standards set forth in 10 CFR 50.92(c), and, accordingly, a finding of 'no significant hazards consideration" is justified.

5.3 Environmental Considerations The proposed amendment does not involve (i) a significant hazards consideration, (ii) a significant change in the types or significant increase in the amounts of any effluent that may be released offsite, or (iii) a significant increase in individual or cumulative occupational radiation exposure. Accordingly, the proposed amendment meets the eligibility criterion for categorical exclusion set forth in 10 CFR 51.22(c)(9). Therefore, pursuant to 10 CFR 51.22(b), no environmental impact statement or environmental assessment need be prepared in connection with the proposed amendment.

3/4.1.1.4 MINIMUM TEMPERATURE FOR CRITICALITY

-O(DRN 05-896. Ch. 41)

This specification ensures that the reactor will not be made critical with the Reactor Coofant System cold leg temperature less than 520'F. This limitation Is required to ensure (1) the moderator temperature coefficient is within its analyzed temperature range, (2) the protective Instrumentation is within Its normal operating range, (3) the pressurizer is capable of being in an OPERABLE status with a steam bubble, and (4) the reactor pressure vessel is above its minimum RTNDr temperature.

WCAP-1601 1-P-A also provides the basis for using only the near 40 EFPD surveillance test result to justify elimination of the near two-thirds of expected core burnup surveillance when applicability requirements are met. Performance of only one measurement at power is justified based on the WCAP-1 601 1-P-A conclusion that ITC startup test data between different operating conditions is poolable.

The applicability requirements in WCAP-1601 1-P-A ensure core designs are not significantly different than those used to benchmark predictions and require that the measured RCS boron concentration meets specific test criteria. This provides assurance that the MTC obtained from the adjusted predicted MTC is accurate.

For fuel cycles that do not meet the applicability requirements in WCAP-1 6011 -P-A, the verification of MTC required prior to entering MODE 1 after each fuel loading is performed by measurement of the isothermal temperature coefficient.
