BROWNS FERRY NUCLEAR PLANT (BFN) - UNIT 1 - RESPONSE TO NRC REQUEST FOR ADDITIONAL INFORMATION REGARDING THE RESTART TESTING PROGRAM (TAC NO. MC7208)

This letter provides additional information concerning the BFN Unit 1 Restart Test Program (RTP) as requested by NRC letter dated June 15, 2005, (Reference 1).

As requested, the enclosure to this letter provides a detailed description of the modifications completed or in progress in support of BFN Unit 1 restart and a description of the testing planned as part of the BFN Unit 1 RTP. For comparison purposes, the enclosure also identifies whether the modifications and testing being implemented were performed for BFN Units 2 and 3 during their restart programs. The enclosure also gives a background of the BFN RTP development, a description of the BFN Unit 1 RTP, and a description of the power ascension testing planned for BFN Unit 1 and comparison to the BFN Unit 3 power ascension testing program.

With the exception of modifications planned to implement Extended Power Uprate, most of the modifications planned for BFN Unit 1 were previously implemented on BFN Units 2 and 3. In addition to testing being performed as part of the RTP, TVA is also performing system and component post-maintenance, post-modification, calibration, normal surveillance, and power ascension testing to ensure systems will operate in accordance with their design requirements.

TVA previously provided a description of the RTP for BFN Units 1 and 3 by letter dated September 27, 1991 (Reference 2), as supplemented by several

U.S. Nuclear Regulatory Commission Page 2 August 15, 2005 additional letters (see the "Background" section in the enclosure to this letter).

In Reference 2, TVA indicated it did not plan to perform a complete Loss of Offsite Power/Loss of Coolant Accident (LOP/LOCA) test for BFN Units 1 and 3 as was performed for BFN Unit 2. As stated in Reference 2, the Unit 2 RTP demonstrated the operation of the electrical system for all three units down to the shutdown board level and the operation of all eight diesel generators, and required Technical Specification diesel generator surveillance testing that simulates LOP/LOCA. As all eight BFN diesel generators have been maintained in an operable condition to support operation of BFN Units 2 and 3, TVA maintains that the testing performed to date, and existing surveillance testing requirements are sufficient to ensure that the BFN Unit 1 diesel generators and electrical system could support safe shut down under a LOP/LOCA event. Therefore, as stated previously in Reference 2, TVA does not intend to perform a complete LOP/LOCA test for BFN Unit 1 as part of the BFN Unit 1 RTP.

There are no new regulatory commitments associated with this submittal. If you have any questions concerning this letter, please contact me at (256) 729-2636.

E-1 ENCLOSURE TENNESSEE VALLEY AUTHORITY BROWNS FERRY NUCLEAR PLANT UNIT 1 RESPONSE TO NRC REQUEST FOR ADDITIONAL INFORMATION REGARDING THE RESTART TESTING PROGRAM I.

INTRODUCTION The following discussion provides TVA's response to the NRC's June 15, 2005 request for additional information regarding the BFN Unit 1 Restart Test Program (RTP) (Reference 1). The BFN Unit 1 RTP is consistent with the BFN Unit 3 RTP as described in previous correspondence with the NRC and as summarized in Section II below.Section III provides a description of the BFN Unit 1 RTP development, and a description of the procedures and administrative controls for the program. This response provides a line-item description of the BFN Unit 1 RTP testing planned and comparison to the testing previously performed under the BFN Units 2 and 3 RTP. This response also provides a description of the modifications being implemented as part of BFN Unit 1 restart and a comparison to modifications performed for BFN Units 2 and 3.

II.

BACKGROUND Following the shutdown of the BFN units in 1985, and as part of activities to restart the units, TVA developed the Restart Test Program for BFN Unit 2, the lead plant for restart. The primary purpose of the RTP was to verify, following extensive plant modifications and resolution of plant configuration issues, that plant systems were capable of meeting their safe shutdown requirements.

The BFN Unit 2 RTP was initially submitted to the NRC by letter dated October 7, 1986 (Reference 2). By letter dated March 3, 1987 (Reference 3),

the NRC requested that TVA provide further information concerning the BFN Unit 2 RTP. TVA responded to the NRC's request by letter dated July 13, 1987 (Reference 4), and resubmitted the BFN Unit 2 RTP description in its entirety to reflect refinements made in the program.

On April 26, 1988, TVA met with the NRC staff to discuss the BFN Unit 2 RTP in detail (Reference 5). During that meeting, the staff requested that TVA describe the differences between industry typical pre-operational test programs, as described in NRC Regulatory Guide 1.68, "Initial Test Programs For Water-Cooled Nuclear Power Plants," Revision 2, August 1978, and the

E-2 BFN Unit 2 RTP. During a follow-up meeting, on June 21, 1988, TVA described these differences (Reference 6). The primary difference was the BFN Unit 2 RTP scope was limited to those system functions that were required to support safe shutdown of the plant considering design basis accidents and transients, and special events.

By letter dated August 12, 1988 (Reference 7), the NRC submitted its Safety Evaluation Report documenting approval of the BFN RTP for Unit 2. The NRC concluded that the BFN Unit 2 RTP was consistent with Regulatory Guide 1.68, Revision 2, and that it would ensure proper verification of the functional integrity of the BFN Unit 2 safety systems.

During this same time frame, TVA submitted to the NRC its Nuclear Performance Plan (NPP) for the restart of the Browns Ferry units. The BFN NPP was initially submitted August 28, 1986 (Reference 8), and subsequently revised. The current version of the NPP (Revision 2) was submitted to the NRC by letter dated October 24, 1988 (Reference 9). The BFN Nuclear Performance Plan included a summary description of the BFN RTP.

On April 14, 1989 (Reference 10), the NRC issued its Safety Evaluation Report on the BFN Nuclear Performance Plan. The NRC's conclusions in that SER concerning acceptability of the BFN RTP were consistent with its earlier conclusions documented in Reference 7. Following completion of activities required to support its restart, including implementation and completion of the RTP, BFN Unit 2 returned to service in May, 1991.

By letter dated September 27, 1991 (Reference 11), TVA submitted a description of the BFN Units 1 and 3 Restart Test Program for NRC review.

As discussed in that letter, TVA modified implementation of the RTP for BFN Units 1 and 3 to incorporate lessons learned during implementation of the BFN Unit 2 RTP. These changes included the coordination of RTP testing with post-modification, post-maintenance, and normal surveillance testing, and use of existing surveillance and testing procedures to the maximum extent possible. TVA also indicated it did not plan to perform a complete Loss of Offsite Power/Loss of Coolant Accident (LOP/LOCA) test as was performed for BFN Unit 2. TVA stated that the Unit 2 RTP demonstrated the operation of the electrical system for all three units down to the shutdown board level and the operation of all eight diesel generators. TVA indicated further that it planned to take credit for the Technical Specification diesel generator surveillance testing that simulates LOP/LOCA.

In response to an NRC request, TVA provided additional information concerning the BFN Units 1 and 3 RTP in a letter dated February 18, 1992 (Reference 12). That letter documented how the BFN Unit 1 and 3 RTP compared to the criteria contained in Regulatory Guide 1.68, Revision 2, and provided a Unit 3 RTP test matrix comparing the testing planned for BFN

E-3 Unit 3 under the RTP to the testing actually performed under the BFN Unit 2 RTP. The response provided similar information for the BFN Units 1 and 3 Power Ascension Testing (PAT) Program. TVA indicated that there were no differences in the comparison of the BFN Units 1 and 3 RTP testing criteria to Regulatory Guide 1.68, Revision 2 over that provided previously for BFN Unit 2 during its June 21, 1988, meeting with the NRC. Differences in testing planned for BFN Units 1 and 3 under the RTP and that actually performed for BFN Unit 2 under its RTP were categorized as follows:

TVA did not plan to re-perform BFN Unit 2 RTP tests that fully satisfied the requirements for Units 1 and 3; Testing to address shared system modes (functions) between Units 2 and 3, and between Units 1, 2, and 3 might be required; and Testing to address the addition of new system modes might be required.

Reference 12 also indicated that as of the date of that letter, TVA had not yet completed development of the BFN Unit 3 Baseline Test Requirements Documents, and would update the Unit 3 RTP test matrix upon completion of that effort. By letters dated December 28, 1992 (Reference 13) and July 19, 1993 (Reference 14), TVA provided updates to the BFN Unit 3 RTP test matrix.

On December 14, 1993, TVA met with the NRC to discuss the BFN Units 1 and 3 RTP in further detail (Reference 15). In Reference 15, the NRC Staff documented its position that it would evaluate the differences between the BFN Units 1 and 3 restart programs and those previously approved for BFN Unit 2. Those programs that remain the same would not be re-evaluated.

Therefore, the purpose of the December 14, 1993 meeting was to ensure that the NRC had a thorough understanding of the BFN Units 1 and 3 RTP, with an emphasis on the differences between the BFN Units 1 and 3 RTP and the BFN Unit 2 RTP. During that meeting, TVA committed to send the NRC a detailed description of the differences between the BFN Units 1 and 3 RTP, and the BFN Unit 2 RTP as described in the associated NRC safety evaluations. By letter dated February 2, 1994 (Reference 16), TVA provided that additional information.

By letter dated August 30, 1994 (Reference 17), the NRC issued a safety evaluation accepting the RTP program for BFN Unit 3. In the cover letter, the NRC indicated that much of the information contained in TVA's February 18, 1992, December 28, 1992, and July 19, 1993 letters pertained only to BFN Unit 3. This refers to the BFN Unit 3 RTP testing matrices provided with TVA's February 18, 1992 letter, and updated by the December 28, 1992 and July 19, 1993 letters that described, on a line-item basis, the BFN Unit 3

E-4 specific testing planned under the RTP and its comparison to testing performed under the BFN Unit 2 RTP.

The cover letter stated further that the NRC Staff's review included examination of procedures developed to support the BFN Unit 3 RTP, which might not be representative of procedures which may be used to support BFN Unit 1 recovery. On this basis, Reference 17 stated that the staff considered only that set of information sufficient to determine the adequacy of the BFN Unit 3 RTP, and should TVA subsequently decide to pursue restart of BFN Unit 1, TVA should submit similar documentation for BFN Unit 1 planned testing.

By letter dated December 13, 2002 (Reference 18), and as supplemented by letter dated February 28, 2003 (Reference 19), TVA submitted to the NRC the proposed regulatory framework for the restart of BFN Unit 1. In that letter, TVA indicated its intent to implement the remaining special programs, including the RTP, in accordance with the implementation precedent and criteria used to restart Unit 3. By letter dated August 14, 2003 (Reference 20), the NRC accepted TVA's proposed approach.

By letter dated June 15, 2005 (Reference 1), the NRC requested that TVA provide detailed information concerning modifications being made as part of BFN Unit 1 restart and a detailed description of the testing planned under the BFN Unit 1 RTP. To provide a more complete picture of the BFN Unit 1 RTP and how it relates to the BFN Unit 3 RTP,Section III below provides a description of the BFN Unit 1 RTP, including a description of the procedures under which the program was developed and is controlled.Section IV below discusses and provides the specific information requested by the NRC RAI, including a line-item description of the specific testing planned under the BFN Unit 1 RTP, and a comparison to that performed under the BFN Units 2 and 3 RTP.

III.

DESCRIPTION OF BFN UNIT 1 RESTART TEST PROGRAM DEVELOPMENT As a component of the BFN Design Basis Verification Program (DBVP), the primary purpose of the BFN Unit 1 RTP is to verify that plant systems are capable of meeting their safe shutdown requirements. To accomplish this objective, TVA performed a Safe Shutdown Analysis (SSA) as part of the BFN DBVP. The SSA, which addresses all three BFN units, is a systematic and comprehensive analysis of the requirements for ensuring the safe shutdown of BFN Units 1, 2, and 3 for transients, accidents, and special events. It documents the safety system actions for which credit has been taken in the UFSAR, reload analyses, and other communications addressing transients, accidents, and special events within the BFN licensing bases. The events considered in the SSA included:

E-5

  • Generator Trip
  • Turbine-Generator Trip with Bypass Failure
  • Pressure Regulator Failure -

Closed

Malfunction (Temperature Decrease)

  • Inadvertent Pump Start
  • Fuel Assembly Insertion
  • Pressure Regulator Failure -

Open

  • Inadvertent Opening of All Bypass Valves
  • Inadvertent Opening of a Safety/Relief Valve
  • Loss of Offsite AC Power
  • Recirculation Control Failure-Decrease
  • Recirculation Pump Trip (One Pump Trip)
  • Recirculation Pump Trip (Two Pump Trip)
  • Recirculation Pump Seizure
  • Recirculation Flow Controller Failure Increasing Flow

Maximum Demand

  • Pipe Break Inside Containment -

Large Break

  • Intermediate Pipe Break Inside Containment
  • Small Pipe Break Inside Containment
  • Pipe Break Inside - Containment and Radiological Effect
  • Fuel Handling Accident
  • Pipe Break Outside Containment
  • Shutdown From Outside of Control Room
  • Overpressure Protection (MSIV Closure - Backup Scram)
  • Rotated or Mis-located Bundle
  • Flood
  • Low Reservoir Downstream Dam Failure
  • Tornado
  • Fire
  • Loss of Fuel Pool Cooling/Makeup From evaluation of the above events, the systems and associated system functions required to ensure safe shutdown were identified. These system functions or "modes" identified in the SSA were then systematically evaluated, and tests required to verify capability of the functions identified.

Testing the modes identified in the SSA under the RTP will verify the capacity

E-6 of the systems to support their required safety functions. Where applicable, these tests will be performed under Extended Power Uprate (EPU) conditions.

Development of the BFN Unit 1 RTP program and identification of the associated BFN Unit 1 RTP test requirements are controlled administratively via BFN Procedure 1-TI-452, "Unit 1 Restart Test Program," which specifies the review and approval of the restart test requirements, associated acceptance criteria, and test results. The RTP test requirements are documented in the BFN Unit 1 Baseline Test Requirements Documents (BTRDs) developed, reviewed, and approved in accordance with BFN Procedure 1-TI-469, "Baseline Test Requirements." Consistent with the BFN Unit 3 RTP, a multi-disciplinary review group (per 1-TI-452, designated the Restart Test Program Review Group or "RTPRG") reviews and approves the RTP test requirements identified for each system, as well as the results of the RTP testing for each system.

In addition to the testing planned for BFN Unit 1 under the RTP, TVA is performing system and component post-maintenance, post-modification, calibration, normal surveillance, and power-ascension testing as required to ensure other systems and system functions will operate within their design requirements. This testing, which is not part of the BFN Unit 1 RTP, is identified and controlled as required in accordance with 10 CFR 50 Appendix B.

The BFN Unit 1 restart testing is controlled in accordance with BFN Procedure 1-TI-453, "Unit 1 Startup Test Instruction." Procedure 1-TI-453 provides coordination, tracking, and control of testing performed on each system. Under Procedure 1-TI-453, System Test Specifications (STS) are developed to define the minimum testing requirements, their bases, acceptance criteria, and the test procedures that will be used to satisfy the test requirements for selected BFN systems. The STS are intended to encompass all functional testing beyond the scope of static installation and minor post-maintenance testing, and includes component tests, loop calibrations, post-modification functional tests, Technical Instructions (TIs),

Special Tests, and Technical Specifications/Technical Requirements surveillance tests. Consistent with the BFN Unit 3 RTP, TVA is utilizing existing surveillance and testing procedures to the extent possible to perform these tests. Where planned testing is not covered by existing procedures, explicit test instructions are developed to perform the testing.

IV. RESPONSE TO NRC REQUEST FOR INFORMATION The NRC's June 15, 2005 request for additional information requested that TVA provide the following information:

E-7 "In order for the staff to independently verify the adequacy of your restart testing program, please describe in detail the modifications that were made and those still in progress or planned and how they were or will be verified to be within the bounds of the original test data. Also, provide a detailed listing and description of the testing that you referred to in your December 13, 2002 letter."

Table 1 identifies the modifications being implemented as part of the BFN Unit 1 restart. The table lists the Design Change Notices (DCNs), sorted by system, provides a detailed description of the modifications and identifies whether a similar DCN was implemented for BFN Units 2 and 3.

Modifications developed primarily to implement EPU have been notated as such and grouped at the end of the table. Portions of other modifications supporting implementation of EPU are notated within their descriptions. A more concise description of the EPU modifications and the associated testing planned for those modifications was provided in TVA's April 25, 2005 letter (Reference 21) providing additional information in support of the BFN Unit 1 Extended Power Uprate application.

Table 1 shows that with the exception of those modifications planned to implement EPU operation, most of the modifications planned for BFN Unit 1 have been implemented previously for BFN Units 2 and 3. Excluding EPU, the design modifications for Unit 1 are the result of like modifications implemented prior to the restart of Units 2 and 3, any changes made on Units 2 and 3 since their restarts, and changes to replace obsolete equipment. A primary consideration throughout the change process in the design, construction, function, and operation of systems being modified, has been unit fidelity. While minor differences exist among Units 1, 2, and 3, largely due to equipment obsolescence, the systems will remain functionally the same.

As discussed in TVA's February 2, 1994 letter concerning the BFN Units 1 and 3 RTP, TVA is not verifying that plant systems and components are within the bounds of the original test data. Rather, the BFN Unit 1 RTP testing requirements and testing acceptance criteria are based on the BFN Safe Shutdown Analysis, and are documented in the BTRDs for each system function credited in the SSA. Therefore, while much of the acceptance criteria remain unchanged since performance of the initial pre-operational testing, the BTRDs establish and document the acceptance criteria based on the revised BFN Unit 1 design bases and design requirements. These acceptance criteria are specified in the applicable test instructions.

As part of the BFN plant modification control process, TVA reviews all Design Change Notices (DCNs) to identify, specify, and document appropriate post-modification testing requirements. The purpose of post-modification testing is to demonstrate conformance with the design requirements of the installed or

E-8 modified component(s), confirm expected system response, and verify that no undesirable effects were created.

DCNs are prepared and controlled in accordance with TVA procedure SPP-9.3, "Plant Modifications and Engineering Change Control," which requires that Design engineers identify and document any required verification and/or special testing requirements. Per TVA Procedure SPP-8.3, "Post Modification Testing," System engineers review the DCNs to confirm that all necessary post modification testing has been specified and are responsible for reviewing and concurring with acceptability of test results.

These programmatic controls ensure for each design change, that the testing required to ensure system performance requirements are met and expected system response is confirmed. Testing is identified and performed with acceptable results prior to turnover of the system for operation. These controls are typical of industry programs developed to ensure compliance with the requirements of 10 CFR 50 Appendix B.

As discussed in Section III above, for each system within the scope of the program, a set of System Test Specifications (STS) are developed to identify the testing required to return the system to service. These STS identify planned RTP testing as well as planned post-modification, post-maintenance, surveillance testing, etc. Due to the extent of the modifications and replacements being implemented on BFN Unit 1, it is not practical to list each and every planned post-modification and post-maintenance test in this response. However, these tests are documented in the STS for each system.

Examples of typically specified post-modification and/or post-maintenance testing include (as applicable):

Verification of proper rotation and setting limits on valves Motor-operated valve (MOV) setting and baseline diagnostics (for GL 89-10 valves)

Leak-rate testing for Primary Containment isolation valves Pump operability testing (verification of rated flow within specified period)

Valve operability testing System flow balancing System and component leak testing Instrument channel calibration and functional testing Protective relay calibration and functional testing Logic system functional testing, System run and confirmation that process parameters are within expected ranges While these tests overlap with testing planned as part of the BFN Unit 1 RTP, they are identified and specified in accordance with the normal design control

E-9 process to ensure that plant systems are capable of meeting their design and operational requirements.

Table 2 provides the matrix of tests planned for BFN Unit 1 under the RTP.

As discussed in the description of the BFN Unit 1 RTP development in Section III above, the RTP test requirements are identified by system "modes" or functions that have been identified in the BFN SSA as required to ensure the capability for safe shutdown of the plant. Therefore Table 2 is organized according to these system modes, which are described in the table and which correlate to the modes identified in the BFN SSA and the associated system Baseline Technical Requirements Documents (BTRDs). The table also identifies whether the test was performed for BFN Units 2 and 3, whether the test is planned for BFN Unit 1, and includes clarifying information where appropriate.

The BFN Unit 1 Power Ascension Testing (PAT) Program is consistent with the PAT Program described for BFN Unit 3 previously in Reference 12.

Table 3 provides a comparison of BFN Unit 1 Power Ascension Testing (PAT) planned to the PAT testing described previously for BFN Unit 3 in Reference 12.
