Tennessee Valley Authority, Post Office Box 2000, Decatur, Alabama 35609-2000 October 12, 2004 TVA-BFN-TS-432 10 CFR 50.90 U.S. Nuclear Regulatory Commission ATTN: Document Control Desk Mail Stop: OWFN P1-35 Washington, D.C. 20555-0001 Gentlemen:
In the Matter of ) Docket No. 50-259 Tennessee Valley Authority BROWNS FERRY NUCLEAR PLANT (BFN) UNIT 1 - COMPLETION OF LICENSE CONDITION 2.C(4)
Pursuant to 10 CFR 50.90, Tennessee Valley Authority (TVA) is submitting a request for an amendment to license DPR-33 for BFN Unit 1. The proposed amendment describes the completion of License Condition 2.C(4) and requests its removal from the license.
The origin of License Condition 2.C(4) began on September 6, 1996 (Reference 1), when TVA submitted Units 1, 2, and 3 Technical Specifications (TS) Change 362 - Improved Technical Specifications (ITS). This change was TVA's proposed conversion package from custom TS to ITS. At the time, Units 2 and 3 were operating and Unit 1 was in long-term lay-up with no plans for return to service. Since TVA was adopting a relatively few Unit 1 TS values that were not supported by design basis documentation, TVA proposed utilizing a License Condition to ensure, in part, that the Unit 1 TS would be supported and reflected by the plant's design basis prior to returning the associated equipment to service. As part of NRC's approval of the ITS for BFN Units 1, 2 and 3 (Amendment 234 - Reference 2),
NRC imposed License Condition 2.C(4), which states:
"The licensee shall review the Technical Specification (TS) changes made by License Amendment No. 234 and any subsequent TS changes, verify that the required analyses and modifications needed to support the changes are complete,
,Cok P-ewey~a -
U.S. Nuclear Regulatory Commission Page 2 October 12, 2004 and submit them for NRC review and approval prior to entering the mode for which the TS applies. This amendment is effective immediately and shall be implemented prior to entering the mode for which the TS applies."
The open items identified during the conversion from custom to ITS were listed on Page 12 of the accompanying Safety Evaluation.
These items were associated with the confirmation of calibration frequencies, instrument check frequencies, system configurations, or setpoints.
TVA's plan for satisfying this License Condition was submitted in Reference 3. This amendment request reflects the implementation of that plan. As detailed in the enclosure, confirmation of the calibration frequencies, instrument check frequencies, system configurations, and setpoints identified by TVA in TS 362 and reflected in the NRC's Safety Evaluation have been provided as part of separate Unit 1 proposed TS requests.
Since the approval of the conversion to ITS, several Unit 1 TS have been approved or are currently under NRC review. TVA has reviewed the TS changes made since the conversion to ITS and the analyses needed to support the Unit 1 TS have been completed.
Since Unit 1 is no longer in a long-term lay-up condition, future Unit 1 TS changes will be treated just like any other operating unit. There will be no need for the License Condition in the future since the Unit 1 supporting analyses will be completed for each proposed TS change.
Therefore, TVA considers License Condition 2.C(4) to be complete and requests its removal it from the license.
With regards to the overall subject of configuration control, TVA will have reasonable assurance that the as-built facility will be reflected by the plant's design basis and TS at the time of Unit 1 restart. This assurance is provided, in part, by:
- Controlling fidelity between the Unit 1 TS and the plant design basis during the BFN shutdown period;
- Implementing the Design Baseline Verification Program, which will validate key plant specific values and setpoints that are reflected in the TS;
U.S. Nuclear Regulatory Commission Page 3 October 12, 2004
- Utilizing TVA's configuration management, 10 CFR 50.59 and UFSAR programs during the development and implementation of the modifications necessary to restart Unit 1, to ensure the affected areas are accurately reflected in the TS; and
- TVA's review of previous TS amendments to identify required Unit 1 changes.
The proposed amendment is necessary to support the restart of Unit 1. TVA requests the amendment be approved by November 1, 2005.
TVA has determined there are no significant hazards considerations associated with the proposed amendment and the change qualifies for a categorical exclusion from environmental review pursuant to the provisions of 10 CFR 51.22(c)(9).
Additionally, in accordance with 10 CFR 50.91(b)(1), TVA is sending a copy of this letter and attachments to the Alabama State Department of Public Health. provides TVA's evaluation of the proposed amendment. provides a mark-up of the proposed license change.
There are no regulatory commitments associated with this submittal. If you have any questions about this amendment, please contact me at (256)729-2636.
I declare under penalty of perjury that the foregoing is true and correct. Executed on October 12, 2004.

1.0 DESCRIPTION
This letter requests an amendment to Operating License DPR-33 for BFN Unit 1. The proposed amendment describes the completion of License Condition 2.C(4) and requests its removal from the license.
The proposed amendment is necessary to support the restart of.
Unit 1. TVA requests the amendment be approved by November 1, 2005.
2.0 PROPOSED AMENDMENT BFN Unit 1 License Condition 2.C(4) states:
"The licensee shall review the Technical Specification (TS) changes made by License Amendment No. 234 and any subsequent TS changes, verify that the required analyses and modifications needed to support the changes are complete, and submit them for NRC review and approval prior to entering the mode for which the TS applies. This amendment is effective immediately and shall be implemented prior to entering the mode for which the TS applies."
The proposed amendment describes the completion of License Condition 2.C(4) and requests its removal from the license.
A mark-up of the License showing the proposed amendment is provided in Enclosure 2.
3.0 BACKGROUND
All three BFN units were voluntarily shutdown by TVA in March 1985. Unit 2 restarted in May 1991 and Unit 3 in November 1995.
Several modifications and the resulting changes to the Units 2 and 3 Technical Specifications (TS) were made during the recovery efforts. Unit 1 has been maintained in a long-term lay-up state.
On September 6, 1996 (Reference 1), TVA submitted Units 1, 2, and 3 TS Change 362 - Improved Technical Specifications, which was TVA's conversion package from custom TS to Improved Technical Specifications (ITS). The Units 1, 2 and 3 ITS were based on NUREG-1433, Standard Technical Specification for BWR/4 Plants, Revision 1. At the time, Units 2 and 3 were operating and Unit 1 was in long-term lay-up with no plans for return to service.
El-i
During the conversion process, a relatively few Unit 1 specific setpoints or configurations adopted the ITS values used for Units 2 and 3. TVA's application identified these items for Unit 1 that must be validated prior to restart or necessary changes made. Since these Unit 1 TS confirmatory items were not supported by design basis documentation, NRC requested (Reference 2) TVA to provide a description of the controls, including license requirements, which would ensure that BFN Unit 1 could not be put into an operating configuration before all required activities were completed.
On December 29, 1997 (Reference 3), in response to the NRC letter, TVA stated that it planned to perform the required analyses and modifications on Unit 1 such that on restart, the Unit 1 plant configuration and analysis basis will be the same or similar to Units 2 and 3. Hence, in TS-362, the proposed Unit 1 ITS were the same as those proposed for Units 2 and 3 except for minor intrinsic unit differences. TVA proposed a License Condition be added to the Unit 1 license. This would ensure that the appropriate modifications and analyses were in place prior to entering modes of operation for which the TS apply. The purpose of the License Condition was to:
- Ensure the changes to the Unit 1 TS, identified in the application for conversion to ITS as lacking the required analysis, were supported and reflected by the plant's design basis prior to returning the associated equipment to service; and
- Allow future TS changes to be made to all three units, during the period that Unit 1 was in a long-term lay-up condition, without requiring Unit 1 supporting analyses be performed prior to submittal or requiring additional license conditions be added for each amendment.
NRC approved TVA's proposed conversion to ITS for BFN Units 1, 2 and 3. As part of the License Amendment(Reference 4), NRC imposed License Condition 2.C(4). Page 12 of the Safety Evaluation states:
"Unit 1 Restart Issues:
The Unit 1 license will contain a restart license condition to require staff acceptance of Unit 1 channel calibration and channel check frequency changes for CTS Tables 3.2.A, 3.2.B, 4.1.B, 4.2.A, 4.2.B made to be consistent with Units 2 and 3. These changes to frequencies have been reflected in the proposed BFN ITS for Unit 1 as the same as those in the proposed ITS for Units 2 and 3. The Unit 1 Calibration frequencies for these functions will be E1-2
validated prior to Unit 1 recovery and changes to the proposed BFN ITS for Unit 1 will be made as necessary. [The DOCS that are affected for this example are 3.3.1.1, All; 3.3.5.1, A3; 3.3.5.2, A8; 3.3.6.1, A12, A13, A14, A15 (partial); 3.3.6.2 A10; and 3.3.7.1, A5.] Staff acceptance of these calibrations and frequencies are shown here as an example of the kinds of reviews that will be required before Unit 1 restarts. Additional issues that will require staff acceptance before Unit 1 restarts exist in other sections of the ITS."
3.1 Closure of the Specific Improved Technical Specification Conversion Open Items TVA's application for conversion to ITS identified the changes for Unit 1 that must be validated prior to Unit 1 recovery or necessary changes made. These changes were listed on Page 12 of the NRC's Safety Evaluation. Each of these changes, the method for validation, and reference to the confirmatory submittal to NRC are provided below.

3.2 Closure of Confirmatory Items associated with Technical Specifications Approved or Proposed since the Conversion to Improved Technical Specifications Since the approval of the conversion to ITS in Amendment 234, several TS have been approved for Unit 1 or are currently under NRC review. These amendments and proposed TS changes have been reviewed to identify any outstanding Unit I supporting analyses which would have to be submitted to NRC. For TS 405 - Alternate Source Term, TVA committed to submit the Unit 1 analyses for a Loss of Coolant, Control Rod Drop and Main Steam Line Break accidents. These analyses were provided to NRC as part of a separate submittal (Reference 7). No other Unit 1 supporting analyses need to be submitted to NRC.
E1-9
3.3 Future Technical Specification Changes Since Unit 1 is no longer in a long-term lay-up condition, future Unit 1 TS changes will be treated just like any other operating unit. There will be no need for the License Condition in the future since the Unit 1 supporting analyses will be included for each proposed Technical Specification change.
4.0 TECHNICAL ANALYSIS
There are no proposed changes to the TS, plant design, change the conditions, operating configurations, or minimum amount of operating equipment associated with this proposed License Amendment.
The open items identified during the conversion from custom to ITS were associated with the confirmation of calibration frequencies, instrument check frequencies, system configurations, or setpoints. The confirmation of these items or necessary revisions has been provided by other proposed TS changes (References 5 and 6).
5.0 REGULATORY SAFETY ANALYSIS The Tennessee Valley Authority (TVA) is submitting an amendment request to license DPR-33 for the Browns Ferry Nuclear Plant Unit 1. The proposed amendment describes the completion of License Condition 2.C(4). BFN Unit 1 License Condition 2.C(4) states:
"The licensee shall review the Technical Specification (TS) changes made by License Amendment No. 234 and any subsequent TS changes, verify that the required analyses and modifications needed to support the changes are complete, and submit them for NRC review and approval prior to entering the mode for which the TS applies. This amendment is effective immediately and shall be implemented prior to entering the mode for which the TS applies."
Confirmation of the required calibration frequencies, instrument check frequencies, system configurations, and setpoints has been provided as part of separate Unit 1 proposed Technical Specification (TS) change requests. Therefore, TVA requests removal of License Condition 2.C(4) from the license.
E-10
5.1 No Significant Hazards Consideration TVA 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 amendment involve a significant increase in the probability or consequences of an accident previously evaluated?
Response: No The proposed amendment does not affect any precursors for accidents described in Chapter 14 of the Browns Ferry Updated Final Safety Analysis Report (UFSAR). The proposed amendment does not change the conditions, operating configurations, or minimum amount of operating equipment assumed in the safety analysis for accident mitigation. No changes are proposed in plant protection or which create new modes of plant operation. Therefore, the proposed amendment does not involve a significant increase in the probability or consequences of an accident previously evaluated.
- 2. Does the proposed amendment create the possibility of a new or different kind of accident from any accident previously evaluated?
Response: No The proposed amendment does not introduce new equipment, which could create a new or different kind of accident.
No new external threats, release pathways, or equipment failure modes are created. Therefore, the implementation of the proposed amendment will not create a possibility for an accident of a new or different type than those previously evaluated.
3.0 Does the proposed amendment involve a significant reduction in a margin of safety?
Response: No El-li
The proposed amendment does not impact the redundancy or availability of equipment credited in the response to accidents described in Chapter 14 of the UFSAR. For these reasons, the proposed amendment does not involve a significant reduction in a margin of safety.
Based on the above, TVA concludes that the proposed amendment present 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.
5.2 Applicable Regulatory Requirements/Criteria As described herein, TVA will have reasonable assurance that the TS will reflect the analyses and evaluations included in the UFSAR at the time of Unit 1 restart. Hence, the requirements of 10 CFR 50.36, Technical Specifications, will be satisfied.
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 the health and safety of the public.
6.0 ENVIRONMENTAL CONSIDERATION
A review has determined that the proposed amendment 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 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(9). Therefore, pursuant to 10 CFR 50.22(b), no environmental impact statement or environmental assessment need.
be prepared in connection with the proposed amendment.
