Subject:
Request For License Amendments Deletion of Hydrogen And Oxygen Analyzer Requirements Consolidated Line Item Improvement Process (TSTF-447, Revision 1) 1.0 Introduction This letter is a request to amend Operating Licenses DPR-71 and DPR-62 for the Brunswick Steam Electric Plant (BSEP), Unit Nos. I and 2.
The proposed license amendments will delete the Technical Specification (TS) requirements for hydrogen and oxygen analyzers contained in TS Section 3.3.3.1, "Post Accident Monitoring (PAM) Instrumentation." The proposed license amendments 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.
The changes are consistent with Revision I of NRC-approved Industry/Technical Specification Task Force (TSTF) Standard Technical Specification Change Traveler, TSTF-447, "Elimination of Hydrogen Recombiners and Change to Hydrogen and Oxygen Monitors." The availability of this TS improvement was announced in the FederalRegister on September 25, 2003, as part of the consolidated line item improvement process (CLIIP).
2.0 Description of Proposed Amendment Consistent with TSTF447, Revision 1, the following TS changes are proposed.

5.0 Technical Analysis PEC has reviewed the safety evaluation (SE) published on September 25, 2003 (i.e., 68 FR 55416), as part of the CLIIP Notice of Availability, as well as the information provided to support TSTF447, Revision 1. Based on this review, PEC has concluded that the justifications presented in the TSTF proposal and the SE prepared by the NRC are applicable to BSEP Units 1 and 2 and justify the incorporation of the changes to the TSs for BSEP Units 1 and 2.
BSEP 04-0098 Enclosure I Page 3 of 5 6.0 Regulatory Analysis A description of this proposed change and its relationship to applicable regulatory requirements and guidance associated with this application is adequately addressed by the NRC Notice of Availability published on September 25, 2003 (i.e., 68 FR 55416), TSTF-447, Revision 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 FederalRegister on September 25, 2003 (i.e., 68 FR 55416), for this TS improvement, PEC is making the following verifications and regulatory commitments.
- 1. PEC has verified that a hydrogen monitoring system (i.e., the H2 and 02 Analyzers) capable of diagnosing beyond design-basis accidents is installed at BSEP Units I and 2 and is making a regulatory commitment to maintain that capability. The H2 and 02 Analyzers will be included in the Technical Requirements Manual (TRM) for each unit.
This regulatory commitment will be implemented within 90 days from the date of approval of this amendment.
- 2. BSEP Units 1 and 2 have inerted containments. PEC has verified that an oxygen monitoring system (i.e., the H2 and 02 Analyzers) capable of diagnosing beyond design-basis accidents is installed at BSEP Units I and 2 and is making a regulatory commitment to maintain that capability. The H2 and 02 Analyzers will be included in the TRM for each unit. This regulatory commitment will be implemented within 90 days from the date of approval of this amendment. provides marked-up TRM pages for Unit 1, which reflect the changes to be made to implement the above commitments. These pages are being submitted for information only and do not require issuance by the NRC.
7.0 No Significant Hazards Consideration PEC has reviewed the proposed no significant hazards consideration determination published on September 25, 2003 (i.e., 68 FR 55416), as part of the CLIIP. PEC has concluded that the proposed determination presented in the notice is applicable to BSEP Units 1 and 2 and the determination is hereby incorporated by reference to satisfy the requirements of 10 CFR 50.91(a).
8.0 Environmental Evaluation PEC has reviewed the environmental evaluation included in the model SE published on September 25, 2003 (i.e., 68 FR 55416), as part of the CLIIP. PEC has concluded that the NRC's findings presented in that evaluation are applicable to BSEP Units 1 and 2 and the evaluation is hereby incorporated by reference for this application.
BSEP 04-0098 Enclosure 1
- *Page 4 of 5 9.0 Precedent This application is being made in accordance with the CLIIP. PEC is not proposing variations or deviations from the TS changes described in TSTF-447, Revision I or the NRC's model SE published on September 25, 2003 (i.e., 68 FR 55416), as part of the CLIIP. However, due to minor differences between the BSEP TSs and the model TSs in NUREG-1433, "Standard Technical Specifications, General Electric Plants BWR/4," Revision 2, certain small variances from the TSTF mark-up changes are necessary. These variances are discussed below and do not affect the no significant hazards consideration determination and environmental evaluation included in the model SE or the adoption and application of TSTF447, Revision 1.
- 1. TSTF-447, Revision 1, modifies Standard Technical Specification (STS) 3.3.3.1, "Post Accident Monitoring (PAM) Instrumentation," by deleting a Note to Condition C, eliminating Condition D, and re-lettering the subsequent Conditions. The BSEP Unit 1 and 2 TSs do not have the Note in Condition C nor is there a need to delete the existing Condition D. Therefore, these changes are not needed to adopt the TSTF.
- 2. The BSEP Unit 1 and 2 TSs have a specific surveillance requirement (i.e., SR 3.3.3.1.2) which requires channel calibration of the Drywell and Suppression Chamber H2 and 02 Analyzers on a 92 day frequency. A similar SR, specific to the Drywell and Containment H2 and 02 Analyzers does not exist in NUREG-1433, Revision 1 and, as such, is not reflected in the TSTF-447, Revision 1, markups. Consistent with the intent of removing the H2 and 02 Analyzers from the TSs, the requirements of BSEP SR 3.3.3.1.2 are deleted and replaced with the designation "Not Used."
Associated with the change to BSEP SR 3.3.1.2, BSEP SR 3.3.1.3 currently requires channel calibration of the PAM instrumentation, except for the Drywell and Suppression Chamber H2 and 02 Analyzers, on a 24 month frequency. Reference to the Drywell and Suppression Chamber H2 and 02 Analyzers is deleted from BSEP SR 3.3.1.3.
- 3. TSTF447, Revision 1, modifies STS Table 3.3.3.1-1, "Post Accident Monitoring Instrumentation," by deleting Functions 10 and 11, for the Drywell and Containment H2 and 02 Analyzers, respectively. In the BSEP Unit 1 and 2 TSs, these Functions are combined in a single entry (i.e., Function 9, Drywvell and Suppression Chamber H2 and 02 Analyzer). Accordingly, this single function is deleted and replaced with the designation "Not Used."
- 4. TSTF-447, Revision 1, modifies STS 5.6.7, "Post Accident Monitoring Report," to reflect the changes discussed in Item 1, above. Since the BSEP Unit 1 and 2 TSs did not require the changes discussed in Item 1, changes to the equivalent BSEP TS 5.6.6 are not required.

- 8. Primary Containment Isolation Valve (PCIV) Position PCIV position, a Category I variable, is provided for verification of containment integrity. In the case of PCIV position, the important information is the isolation status of the containment penetration. The LCO requires one channel of valve position indication in the control room to be OPERABLE for each active PCIV in a containment penetration flow path, i.e., two total channels of PCIV position indication for a penetration flow path with two active valves. For containment penetrations with only one active PCIV having control room indication, Note (b) requires a single channel of valve position indication to be OPERABLE. This is sufficient to redundantly verify the isolation status of each isolable penetration via indicated status of the active valve, as applicable, and prior knowledge of passive valve or system boundary status. If a penetration flow path is isolated, position indication for the PCIV(s) in the associated penetration flow path is not needed to determine status. Therefore, the position indication for valves in an isolated penetration flow path is not required to be OPERABLE.
The PCIV position PAM instrumentation consists of position switches, associated wiring and control room indication for active PCIVs (check valves and manual valves are not required to have position indication).
Therefore, the PAM Specification deals specifically with these instrument channels.

- 10. Drvwell Area Radiation Drywell area radiation is a Category I variable provided to monitor the potential of significant radiation releases and to provide release assessment for use by operators in determining the need to invoke site emergency plans. Post accident drywell area radiation levels are monitored by four instruments, each with a range of 1 R/hr to 10 R/hr.
The outputs of these channels are indicated and recorded in the control room. Therefore, the PAM Specification deals specifically with this portion of the instrument channel.
APPLICABILITY The PAM instrumentation LCO is applicable in MODES 1 and 2. These variables are related to the diagnosis and preplanned actions required to mitigate DBAs. The applicable DBAs are assumed to occur in MODES 1 and 2. In MODES 3, 4, and 5, plant conditions are such that the likelihood of an event that would require PAM instrumentation is extremely low; therefore, PAM instrumentation is not required to be OPERABLE in these MODES.
ACTIONS Note 1 has been added to the ACTIONS to exclude the MODE change restriction of LCO 3.0.4. This exception allows entry into the applicable MODE while relying on the ACTIONS even though the ACTIONS may eventually require plant shutdown. This exception is acceptable due to (continued)
