COLUMBIA GENERATING STATION, DOCKET NO. 50-397 LICENSE AMENDMENT REQUEST TO REVISE TECHNICAL SPECIFICATIONS TO ADOPT TSTF-535 REVISION 0
Dear Sir or Madam:
Pursuant to 10 CFR 50.90, Energy Northwest is submitting a request for an amendment to the Technical Specifications (TS) for Columbia Generating Station (Columbia).
The proposed amendment modifies the TS definition of "Shutdown Margin" (SDM) to require calculation of the SDM at a reactor moderator temperature of 68 0 F or a higher temperature that represents the most reactive state throughout the operating cycle.This change is needed to address new Boiling Water Reactor (BWR) fuel designs which may be more reactive at shutdown temperatures above 68°F." Attachment 1 provides a description of the proposed change, the requested confirmation of applicability, and plant specification verifications." Attachment 2 provides the existing TS pages marked up to show the proposed change." Attachment 3 provides revised (clean) TS pages.Energy Northwest requests approval of the proposed License Amendment within one year of the date of this letter with the amendment being implemented within 60 days thereafter.
There are no new regulatory commitments contained in this request.In accordance with 10 CFR 50.91, a copy of this application, with attachments, is being provided to the designated Washington State Official.If you should have any questions regarding this submittal, please contact Ms. L. L.Williams, Licensing Supervisor, at 509-377-8148.

LICENSE AMENDMENT REQUEST TO REVISE TECHNICAL SPECIFICATIONS TO ADOPT TSTF-535 REVISION 0 Attachment 1 Page 1 of 3 DESCRIPTION AND ASSESSMENT
1.0 DESCRIPTION
The proposed amendment modifies the Technical Specifications (TS) definition of"Shutdown Margin" (SDM) to require calculation of the SDM at a reactor moderator temperature of 68 0 F or a higher temperature that represents the most reactive state throughout the operating cycle. This change is needed to address new Boiling Water Reactor (BWR) fuel designs which may be more reactive at shutdown temperatures above 68°F.2.0 ASSESSMENT
2.1 Applicability
of Published Safety Evaluation Energy Northwest has reviewed the model safety evaluation dated February 26, 2013, as part of the Federal Register Notice of Availability.
This review included a review of the NRC staff's evaluation, as well as the information provided in TSTF-535 Revision 0,"Revise Shutdown Margin Definition to Address Advanced Fuel Designs." Energy Northwest has concluded that the justifications presented in the TSTF-535 proposal and the model safety evaluation prepared by the NRC staff are applicable to Columbia Generating Station (Columbia) and justify this amendment for the incorporation of the changes to the Columbia TS.2.2 Optional Changes and Variations Energy Northwest is not proposing any variations or deviations from the TS changes described in TSTF-535, Revision 0, or the applicable parts of the NRC staff's model safety evaluation dated February 26, 2013.3.0 REGULATORY ANALYSIS 3.1 No Significant Hazards Consideration Determination Energy Northwest requests adoption of TSTF-535 Revision 0, which is an approved change to the standard technical specifications (STS), into the Columbia TS. The proposed amendment modifies the TS definition of SDM to require calculation of the SDM at a reactor moderator temperature of 68°F or a higher temperature that represents the most reactive state throughout the operating cycle.Energy Northwest has evaluated whether or not a significant hazards consideration is involved with the proposed amendment(s) 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.
LICENSE AMENDMENT REQUEST TO REVISE TECHNICAL SPECIFICATIONS TO ADOPT TSTF-535 REVISION 0 Attachment 1 Page 2 of 3 The proposed change revises the definition of SDM. SDM is not an initiator to any accident previously evaluated.
Accordingly, the proposed change to the definition of SDM has no effect on the probability of any accident previously evaluated.
SDM is an assumption in the analysis of some previously evaluated accidents and inadequate SDM could lead to an increase in consequences for those accidents.
However, the proposed change revises the SDM definition to ensure that the correct SDM is determined for all fuel types at all times during the fuel cycle. As a result, the proposed change does not adversely affect the consequences of any accident previously evaluated.
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 revises the definition of SDM. The change does not involve a physical alteration of the plant (i.e., no new or different type of equipment will be installed) or a change in the methods governing normal plant operations.
The change does not alter assumptions made in the safety analysis regarding SDM.Therefore, the proposed change does not create the possibility of a new or different kind of accident from any accident previously evaluated.
- 3. Does the proposed change involve a significant reduction in a margin of safety?Response:
No.The proposed change revises the definition of SDM. The proposed change does not alter the manner in which safety limits, limiting safety system settings or limiting conditions for operation are determined.
The proposed change ensures that the SDM assumed in determining safety limits, limiting safety system settings or limiting conditions for operation is correct for all BWR fuel types at all times during the fuel cycle.Therefore, the proposed change does not involve a significant reduction in a margin of safety.Based on the above, Energy Northwest concludes that the proposed change 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.
LICENSE AMENDMENT REQUEST TO REVISE TECHNICAL SPECIFICATIONS TO ADOPT TSTF-535 REVISION 0 Attachment 1 Page 3 of 3 3.2 Conclusions In conclusion, based on the considerations discussed above, (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.4.0 ENVIRONMENTAL EVALUATION The proposed change would change a requirement with respect to installation or use of a facility component located within the restricted area, as defined in 10 CFR 20, or would change an inspection or surveillance requirement.
However, the proposed change does not involve (i) a significant hazards consideration, (ii) a significant change in the types or significant increase in the amounts of any effluents that may be released offsite, or (iii) a significant increase in individual or cumulative occupational radiation exposure.
Accordingly, the proposed change 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 change.
