Attachment 1 Discussion of Change Surry Power Station Units 1 and 2 Virginia Electric and Power Company (Dominion)
DISCUSSION OF CHANGE Introduction Pursuant to 10 CFR 50.90, Virginia Electric and Power Company (Dominion) requests a change to the Technical Specifications (TS) for Surry Power Station Units 1 and 2. The proposed change makes administrative changes to adopt the format for topical report references as described in Industry/Technical Specifications Task Force Traveler, TSTF-363 Rev. 0, "Revised Topical Report References in ITS 5.6.5, COLR." There are no changes to the Bases related to this change.
The proposed change has been reviewed, and it has been determined that no significant hazards consideration exists, as defined in 10 CFR 50.92. In addition, it has been determined that the change qualifies for categorical exclusion from an environmental assessment as set forth in 10 CFR 51.22(c)(9); therefore, no environmental impact statement or environmental assessment is needed in connection with the approval of the proposed change.
Background
Reload design and safety analysis methodology topical reports are updated and/or supplemented periodically for both administrative and technical reasons. If there is a revision number change or a supplement addition to a methodology reference in the Core Operating Limits Report (COLR) section, a Technical Specifications change must be made to reflect the change. Removal of reference revision numbers and dates will reduce the number of administrative Technical Specification changes required in the future due to topical report revisions or supplements, and will eliminate unnecessary expenditure of NRC and Dominion resources.
The format of the COLR section references and the requirement for the inclusion of detailed references are described in NUREG-1431 Vol. 1, Rev. 2 (NRC Standard Technical Specifications) and TSTF-363 Rev. 0. The expectations for COLR references are these:
- 1) In the Technical Specifications, identify the topical reports(s) by number and title, or identify the staff Safety Analysis Report for a plant specific methodology by NRC letter and date.
- 2) The COLR will contain the complete identification for each of the TS referenced topical reports used to prepare the COLR (i.e., report number, title, revision, date, and any supplements).
TSTF-363 explains the purpose for this change:
"As stated in the letter, this method of referencing topical reports would allow licensees to use current topical reports to support limits in the COLR without having to submit an amendment to the facility operating license every time the topical report Page 1of 4
is revised. The COLR would provide specific information identifying the particular approved topical reports used to determine the core limits for the particular cycle in the COLR report. This would eliminate unnecessary expenditure of NRC and licensee resources, and would ease the burden of TS submittal and approval needed to license reload fuel."
There are two topical report revisions currently planned that would require two separate licensing actions without this change. The first is the adoption of Revision 2 of the Reload Design Methodology Topical Report (VEP-FRD-42) currently being reviewed by the NRC (Reference 1). The second is the revision of VEP-FRD-42 to include use of the CASMO and SIMULATE models. The NRC safety evaluation report (SER) for the CASMO/SIMULATE topical report was received March 12, 2003 (Reference 2).
Therefore, this change will immediately accomplish the purpose of reducing unnecessary expenditure of NRC and Dominion resources.
Description of Proposed Change The specific change to the Surry Units 1 and 2 Technical Specifications is proposed as follows:
- Revise TS 6.2.C to eliminate revision numbers and dates from topical reports listed in the REFERENCES section. Delete associated information detailing which limits are associated with each reference.
- Revise TS 6.2.C reference 2f (WCAP-12610-P-A) to reflect the approval status.
The COLR will contain the complete identification for each of the TS referenced topical reports used to prepare the COLR (i.e., report number, title, revision, date, and any supplements). Associated information detailing which limits are associated with each reference will also be relocated to the COLR.
Safety Implications of the Proposed Change The proposed change to the Surry Technical Specifications is administrative in nature.
The proposed change does not alter the operation of the station in any way, nor are any plant modifications being proposed. Furthermore, the current Surry licensing and design bases are not being changed, nor is the margin of safety assumed in the plant accident analyses being affected. Consequently, there is no safety significance associated with the proposed administrative change.
Evaluation of Sinificant Hazards Consideration Dominion has reviewed the requirements of 10 CFR 50.92 as they relate to the proposed administrative change to the Surry Power Station Units 1 and 2 Technical Specifications (TS). Due to the strictly administrative nature of the proposed TS change, we have determined that a significant hazards consideration does not exist.
The basis for this determination is provided as follows:
Page 2 of 4
- 1. Does the proposed license amendment involve a significant increase in the probabilitv or conseguences of an accident previously evaluated?
The proposed change is administrative in nature and as such does not impact the condition or performance of any plant structure, system or component. The proposed administrative change does not affect the initiators of any previously analyzed event or the assumed mitigation of accident or transient events. As a result, the proposed change to the Surry Technical Specifications does not involve any increase in the probability or the consequences of any accident or malfunction of equipment important to safety previously evaluated since neither accident probabilities nor consequences are being affected by this proposed administrative change.
- 2. Does the ro2osed license amendment create the ossibilitv of a new or different kind of accident from any accident previouslv evaluated?
The proposed change is administrative in nature, and therefore does not involve any changes in station operation or physical modifications to the plant. In addition, no changes are being made in the methods used to respond to plant transients that have been previously analyzed. No changes are being made to plant parameters within which the plant is normally operated or in the setpoints, which initiate protective or mitigative actions, and no new failure modes are being introduced. Therefore, the proposed administrative change to the Surry Technical Specifications does not create the possibility of a new or different kind of accident or malfunction of equipment important to safety from any previously evaluated.
- 3. Does the Proposed amendment involve a significant reduction in a margin of safetv?
The proposed change is administrative in nature and does not impact station operation or any plant structure, system or component that is relied upon for accident mitigation.
Furthermore, the margin of safety assumed in the plant safety analysis is not affected in any way by the proposed administrative change. Therefore, the proposed change to the Surry Technical Specifications does not involve any reduction in a margin of safety.
Environmental Assessment This amendment request meets the eligibility criteria for categorical exclusion set forth in 10 CFR 51.22(c)(9) as follows:
(i) The amendment involves no significant hazards consideration.
As described above, the proposed administrative TS change does not involve a significant hazards consideration.
(ii) There is no significant change in the types or significant increase in the amounts of any effluents that may be released offsite.
Page 3 of 4
The proposed administrative TS change does not involve the installation of any new equipment or the modification of any equipment that may affect the types or amounts of effluents that may be released offsite. Plant operation is not affected in any manner by this proposed administrative change. Therefore, there is no significant change in the types or significant increase in the amounts of any effluents that may be released offsite.
(iii) There is no significant increase in individual or cumulative occupational radiation exposure.
The proposed administrative TS change does not involve plant physical changes or changes in the method of plant operation. Therefore, there is no significant increase in individual or cumulative occupational radiation exposure.
Based on the above assessment, Dominion concludes that the proposed change meets the criteria specified in 10 CFR 51.22 for a categorical exclusion from the requirements of 10 CFR 51.22 relative to requiring a specific environmental assessment or impact statement by the Commission.
Conclusion The proposed TS change is administrative in nature. Neither station design nor operation is being affected. The Station Nuclear Safety and Operating Committee (SNSOC) and the Management Safety Review Committee (MSRC) have reviewed the proposed change and have concluded that this change does not involve a significant hazards consideration and will not endanger the health and safety of the public.
