Enclosure 1 Browns Ferry Nuclear Plant (BFN)

Units 1, 2, and 3 Technical Specifications (TS) Change 422 Eliminate Requirements for Hydrogen Monitors Using the Consolidated Line Item Improvement Process Description and Assessment

1.0 DESCRIPTION

The proposed license amendment deletes TS references to the hydrogen monitors in TS 3.3.3.1, "Post Accident Monitoring (PAM) Instrumentation." The proposed TS changes support implementation of the revisions to 10 CFR 50.44, "Standards for Combustible Gas Control System in Light-Water-Cooled Power Reactors," that became effective on October 16, 2003.

2.0 DESCRIPTION

OF PROPOSED AMENDMENT Consistent with the NRC-approved Revision 1 of TSTF-447, the proposed TS changes include:

  • TS 3.3.3.1, Condition E, Reference to deleted Condition D is removed
  • Table 3.3.3.1-1 Item 7, Drywell and Torus H2 Analyzer is deleted Existing BFN TS vary from Standard TS (STS) in that a different Channel Calibration Surveillance Requirement (SR) frequency is prescribed for the hydrogen monitors than that specified in STS as differentiated in BFN SRs 3.3.3.1.2 and 3.3.3.1.4. The deletion of the hydrogen monitors from TS likewise requires these two SRs be modified as shown in the attached TS mark-ups to remove the references to the

hydrogen monitors. These additional changes are administrative and are consistent with TSTF-447.

To avoid renumbering and formatting changes that result from the deletion of the above requirements related to hydrogen monitors, the term "deleted" will be inserted as shown in the TS mark-ups. BFN does not have hydrogen recombiners, so no changes to TS are necessary in this regard. Also, requirements for the Drywell and Torus oxygen monitors have been previously removed from BFN TS and are located in the Technical Requirements Manual (TRM). Therefore, no additional TS changes are needed for the relocation of oxygen monitors. As described in NRC-approved Revision 1 of TSTF-447, the changes to TS requirements result in changes to various TS Bases sections. The TS Bases changes will be submitted with a future update in accordance with TS 5.5.10, "Technical Specifications (TS) Bases Control Program."

3.0 BACKGROUND

The background for this application is adequately addressed by the NRC Notice of Availability published on September 25, 2003 (68 FR 55416) (Reference 1), TSTF-447, the documentation associated with the 10 CFR 50.44 rulemaking, and other related documents.

4.0 REGULATORY REQUIREMENTS AND GUIDANCE The applicable regulatory requirements and guidance associated with this application are adequately addressed by the NRC Notice of Availability published on September 25, 2003 (68 FR 55416), TSTF-447 (Reference 1), the documentation associated with the 10 CFR 50.44 rulemaking, and other related documents.

5.0 TECHNICAL ANALYSIS

As noted in Section 2.0, BFN does not utilize hydrogen recombiners, and the Drywell and Torus oxygen monitors have been previously removed from TS (Reference 2). In addition, NRC has approved the designation of the oxygen monitors as Regulatory Guide 1.97 Category 3 instruments (Reference 3) for BFN. In the revision to 10 CFR 50.44, "Standards for Combustible Gas Control System in Light-Water-Cooled Power Reactors," that became effective on October 16, 2003, NRC indicated that existing oxygen monitoring commitments for currently licensed plants were sufficient to meet the revised rule.

E1-2

TVA has reviewed the safety evaluation (SE) published on September 25, 2003 (68 FR 55416) as part of the CLIIP Notice of Availability. This verification included a review of the NRC staff's SE, as well as the supporting information provided to support TSTF-447. TVA has concluded that the justifications presented in the TSTF proposal and the SE prepared by the NRC staff are applicable to BFN and justify this amendment for the incorporation of the changes to the BFN 1, 2, and 3 TS.

6.0 REGULATORY ANALYSIS

A description of this proposed change and its relationship to applicable regulatory requirements and guidance was provided in the NRC Notice of Availability published on September 25, 2003 (68 FR 55416) (Reference 1), TSTF-447, Rev. 1, the documentation associated with the 10 CFR 50.44 rulemaking, and other related documents.

6.1 Verification and Commitments As discussed in the model SE published in the Federal Register on September 25, 2003 (68 FR 55416) for this TS improvement, TVA is making the following verifications and regulatory commitments. BFN Unit 1 is currently in a prolonged outage and the hydrogen/oxygen monitors are not in service. Therefore, the below commitments reflect the current operating status of the three BFN units.

1. TVA has verified that a hydrogen monitoring system capable of diagnosing beyond design-basis accidents is installed at BFN Units 2 and 3, and will be installed on Unit 1 prior to restart. TVA is making a regulatory commitment to maintain that capability to the level of Regulatory Guide 1.97, Category 3. The hydrogen monitors will be included in the TRM. This regulatory commitment will be implemented at the same time as TS-447 is implemented at BFN.
2. TVA has verified that an oxygen monitoring system capable of verifying the status of the inerted containment is installed at BFN Units 2 and 3, and will be installed on Unit 1 prior to restart. TVA is making a regulatory commitment to maintain that capability to the level of Regulatory Guide 1.97, Category 3. The oxygen monitors are currently included in the BFN Unit 1, 2, and 3 TRMs.

E1-3

7.0 NO SIGNIFICANT HAZARDS CONSIDERATION TVA has reviewed the proposed no significant hazards consideration determination published on September 25, 2003 (68 FR 55416) (Reference 1) as part of the CLIIP. TVA has concluded that the proposed determination presented in the notice is applicable to BFN Units 1, 2, and 3, and the determination is hereby incorporated by reference to satisfy the requirements of 10 CFR 50.91 (a).

8.0 ENVIRONMENTAL EVALUATION TVA has reviewed the environmental evaluation included in the model SE published on September 25, 2003 (68 FR 55416)

(Reference 1) as part of the CLIIP. TVA has concluded that the staff's findings presented in that evaluation are applicable to BFN Units 1, 2, and 3, and the evaluation is hereby incorporated by reference for this application.

9.0 PRECEDENT This application is being made in accordance with the CLIIP.

TVA is not proposing variations or deviations from the TS changes described in TSTF-447 or the NRC staff's model SE published on September 25, 2003 (68 FR 55416)

(Reference 1).
