Enclosure Responses to NRC Requests For Additional Information - Developmental Revision I Technical Specification Section 3.8

Background

By letter dated June 16, 2014, Tennessee Valley Authority (TVA) submitted the Watts Bar Nuclear Plant (WBN) Unit 2 Developmental Revision I of the Technical Specifications (TS) and TS Bases, and Developmental Revision D of the WBN Unit 2 Technical Requirements Manual (TRM) and TRM Bases to the Nuclear Regulatory Commission (NRC) (Reference 1). By electronic mail (email) dated October 8, 2014, the NRC provided a set of requests for additional information (RAIs) regarding Developmental Revision I of TS Sections 3.8 and 5.7 (Reference 2). By letter dated February 27, 2015, TVA submitted responses to the Reference 2 RAIs (Reference 3). By email dated April 27, 2015, the NRC provided a draft set of RAIs regarding outstanding issues on TS Section 3.8 (Reference 4).

The following responses to the Reference 4 RAIs address the NRC staff concerns that were communicated to TVA during the public meeting held in Rockville, MD on April 30, 2015.

NRC RAI 1 TS Section 3.8.1 TS Section 3.8.1 is related to operating requirements and surveillance testing of onsite Diesel Generators (DGs) 2A-A and 2B-B. The staff notes that:

1. All four DGs are required to be operable with Unit 2 in Modes 1, 2, 3, or 4.

2. Several DG surveillances in TS Section 3.8.1 are precluded by a note stating, For DGs 2A-A and 2B-B Surveillance shall not be performed in MODE 1, 2, 3, or 4.

The current licensing basis (CLB) of WBN Units 1 and 2 requires support systems such as essential raw cooling water and the component cooling system in each train to be operable.

The CLB states that the minimum combined safety requirements for one accident unit and one non-accident unit or two non-accident units are met by two pumps on the same plant train. With one unit in a shutdown mode and the other unit in Mode 1, some or all the 'common' loads may be operating and can potentially impact the testing of systems/components associated with the shutdown units. Based on the above observations, in its RAI the staff asked the applicant to clarify how all four DGs will be tested to satisfy the surveillance requirements (SRs) for each operating unit.

In response to the RAI, TVA stated that:

1. In the Safety Evaluation related to WBN Unit 1 License Amendment 89, dated November 22, 2011 (Reference 14), Section 3.2, Need for Proposed Change, the NRC accepted proposed changes to allow performance of the preoperational integrated safeguards test of WBN Unit 2 with WBN Unit 1 in MODE 1, 2, 3, or 4.

2. If the NRC grants an Operating License to WBN Unit 2, the proposed changes to the WBN Unit 1 TSs will allow periodic performance of the Surveillances on WBN Unit 2 in MODE 5 or 6 with WBN Unit 1 in MODE 1, 2, 3, or 4.

3. The guidance provided by the Commission in SECY-07-0096, allows the applicant to maintain TS requirements for Unit 2 similar to the requirements for Unit 1.

CNL-15-094 E-1

Enclosure Responses to NRC Requests For Additional Information - Developmental Revision I Technical Specification Section 3.8 The staff notes that:

1. The preoperational integrated safeguards test is one time testing required to validate the design and functional capabilities of the plant systems prior to full power operation, compared to the TS surveillances which will be performed routinely over the life of the operating units.

2. SECY-07-0096 also stated that significant changes to the licensing approach would be allowed as necessary to support dual unit operation.

The staff determined that the applicants response did not clarify the impact on safe shutdown capability of the operating unit when equipment required for dual unit operation is removed from service for testing purposes. At WBN Units 1 and 2, the load group A and load group B philosophy for dual unit operation does not appear to provide independence between redundant and/or corresponding components.

The staff considers the applicants response to be inadequate and considers this an open item.

TVA Response The proposed Unit 2 TS SR Notes effectively remove the Mode restriction from the Unit 2 6.9 kV shutdown boards and DGs to allow testing with Unit 2 in Mode 5 or 6 and with Unit 1 in Mode 1, 2, 3, or 4. The existing Unit 1 TS SR Notes effectively remove the Mode restriction from the Unit 1 6.9 kV shutdown boards and DGs to allow testing with Unit 1 in Mode 5 or 6 and with Unit 2 in Mode 1, 2, 3, or 4.

The on-site distribution system at WBN is divided into independent load groups which provide independence of the Emergency Core Cooling Systems (ECCS) between trains and units. This design allows components in one load group to be removed from service or tested without imposing an impact to the redundant train or a significant impact to the operation of the opposite unit. The 6.9 kV shutdown board in each group is protected by an independent set of undervoltage and protective relaying. Additionally, there is no sharing of DGs between load groups. Some systems are common to both units, e.g., Essential Raw Cooling Water (ERCW)

System, Component Cooling System, Auxiliary Air, and various engineered safety feature (ESF) heating, ventilation, and air conditioning (HVAC) loads. Some of these system components are powered from 6.9 kV Shutdown Board 2A-A or 2B-B, which are provided with standby power from the DG 2A-A or 2B-B, respectively. However, redundant trains of common systems are still on independent load groups and therefore, testing will not result in loss of the function.

Although the performance of a Unit 2 loss of offsite power (LOOP) / ESF test with Unit 1 in Mode 1 will result in entering Unit 1 TS Conditions for equipment made inoperable, performance of the SR will not cause a loss of safety function.

The portions of the 6.9 kV and 480 V electrical distribution system that are not being tested will not be significantly affected. The portions of the 6.9 kV and 480 V electrical distribution systems being tested will be de-energized at various points during the test, but significant perturbation of Unit 1 ESF equipment is not anticipated.

CNL-15-094 E-2

Enclosure Responses to NRC Requests For Additional Information - Developmental Revision I Technical Specification Section 3.8 The 120 V vital AC and 125 V vital DC systems supported by the unit / train being tested could be challenged due to loss of normal AC power to the associated inverter and loss of the vital battery charger. However, the vital AC board and vital battery board will remain energized by the associated vital battery. Therefore, a loss of a vital board is unlikely and is not anticipated.

For example, during performance of the Unit 2 Train A LOOP / ESF test, the normal power supply to Vital Inverters 1-III and 2-III and the power supply to Vital Battery Charger III will be lost while testing personnel verify that the affected components are in their post-LOOP positions. During this time, LCO 3.8.4, DC Sources - Operating, is not met (loss of power to Vital Battery Charger III). LCO 3.8.4, Condition A, requires power be restored to Vital Battery Charger III within 2 hours2.314815e-5 days 5.555556e-4 hours 3.306878e-6 weeks 7.61e-7 months . However, during performance of the test, Vital Battery Board III remains energized from Vital Battery III, and Inverters 1-III and 2-III remain energized from Vital Battery III. Therefore, the loss of power to Vital Battery Charger III and normal power to Vital Inverters 1-III and 2-III does not result in a loss of function. The expected duration of this condition during the test is approximately 30 minutes. If necessary, the test can be aborted and normal power can be restored to Vital Battery Charger III in approximately 5 to 10 minutes.

Some common systems could be affected during the test (primarily, ERCW, Core Cooling System (CCS), Auxiliary Air and safety-related ventilation systems). For example, during the performance of SR 3.8.1.9, single largest load reject test, the running ERCW pump associated with the DG being tested is placed in the pull-to-lock position to verify acceptable DG response to a loss of the single largest load. This action results in LCO 3.7.8, Essential Raw Cooling Water (ERCW) System, not being met. However, fluctuations in ERCW System pressure should not significantly affect CCS heat exchanger operation or Unit 1 containment temperatures due to the short duration of the test (approximately 30 minutes). Additionally, during performance of the testing, main control room operators monitor ERCW System pressure and make adjustments as necessary to maintain system pressure.

The flexibility of the CCS allows alternate system alignments during the test to minimize impacts to the operating unit. For example, during a test of DG 2A-A, CCS Pump C-S is running to maintain cooling on CCS Train B (provides cooling to both units). CCS pump 2A-A runs in parallel with CCS pump 2B-B to ensure Unit 2 CCS Train A flow. CCS pump 1A-A runs in parallel with CCS pump 1B-B to maintain cooling to the Unit 1 CCS Train A header. Therefore, CCS operation to Unit 1 is unaffected during the test.

Auxiliary air is powered from Unit 2 6.9 kV shutdown boards. However, the normal lineup is for control air (powered from Unit 1 6.9 kV shutdown boards) to provide the motive force for ESF system components, with auxiliary air providing the safety-related backup. Therefore, although the affected ESF trains will be inoperable without a backup auxiliary air compressor, these components will continue to be functional throughout the Unit 2 testing. With one train of auxiliary air unavailable, the applicable TS Conditions of the following LCOs will be entered:

LCO 3.6.9, Emergency Gas Treatment System, LCO 3.7.4, Atmospheric Dump Valves, LCO 3.7.5, Auxiliary Feedwater System, LCO 3.7.10, Control Room Emergency Ventilation System, LCO 3.7.11, Control Room Emergency Air Temperature Control System, and LCO 3.7.12, Auxiliary Building Gas Treatment System. The duration of the TS Condition entries for an unavailable auxiliary air compressor is expected to be no longer than two hours.

CNL-15-094 E-3

Enclosure Responses to NRC Requests For Additional Information - Developmental Revision I Technical Specification Section 3.8 In addition, prior to performance of the testing, the following are performed to ensure safe shutdown capability is maintained and to minimize impacts on the operating unit:

x Testing is performed on 6.9 kV shutdown boards and DGs associated with the unit in Mode 5 or 6.

x For Train A testing, Train B is protected. For Train B testing, Train A is protected.

x Each vital battery charger is verified to be aligned to its normal power supply.

x Each 6.9 kV shutdown board is verified to be aligned to its normal power supply.

SR 3.8.1.9 This SR requires the performance of the single largest load reject test for each DG. This test is performed with the DG supplying the 6.9 kV shutdown board, immediately following performance of the LOOP / ESF actuation test (SR 3.8.1.19). Therefore, the test begins with the DG on the 6.9 kV shutdown board with ESF loads connected and the selected ERCW pump running. The ERCW pump switch is then taken to the pull-to-lock position, thereby removing the single largest load from the DG. During the time that the ERCW pump switch is in the pull-to-lock position that train of ERCW is considered inoperable and the appropriate Action of LCO 3.7.8, Essential Raw Cooling Water (ERCW) System, is entered.

SR 3.8.1.10 This SR requires the performance of the full load reject test for each DG. This test is performed with the DG aligned to the 6.9 kV shutdown board connected to offsite power. The DG is loaded as close to design basis conditions as possible (approximately 4300 kW and 3100 kVAR). DG temperatures are then allowed to stabilize. Once conditions are met, a safety injection signal is simulated to trip open the DG output breaker. The impact to the 6.9 kV shutdown board is minimal, and the 6.9 kV shutdown board should remain energized to meet the acceptance criteria for the test.

SR 3.8.1.11 and SR 3.8.1.16 This SR requires the performance of the LOOP test for each DG. After the LOOP is simulated, the DG is verified to start, energize the 6.9 kV shutdown board, auto-connect the emergency loads, achieve steady state voltage and frequency, and operate for at least five minutes. After operating for at least five minutes, the DG is synchronized with offsite power, the loads are transferred to offsite power, and the DG is returned to a ready-to-load condition.

This test is performed with the normal feeder for 6.9 kV Shutdown Board 2A-A open, thereby isolating the 6.9 kV shutdown board from the common station service transformer (CSST). This action places Unit 1 in LCO 3.8.1, Condition A for a loss of offsite power source.

Auxiliary air is powered from Unit 2 6.9 kV shutdown boards, therefore one of the auxiliary air trains will be impacted by de-energizing one of the two Unit 2 6.9 KV shutdown boards.

However, the normal lineup is for control air (powered from Unit 1 6.9 kV shutdown boards) to provide the motive force for ESF system components, with auxiliary air providing the safety-related backup. Therefore, although the affected ESF trains will be inoperable without a backup auxiliary air compressor, these components will continue to be functional throughout the CNL-15-094 E-4

Enclosure Responses to NRC Requests For Additional Information - Developmental Revision I Technical Specification Section 3.8 Unit 2 testing. With one train of auxiliary air unavailable, the applicable Conditions of TS LCOs 3.6.9, 3.7.4, 3.7.5, 3.7.10, 3.7.11, and 3.7.12 will be entered.

When this test is performed on Train 2B, CCS pump 1B is re-aligned to ensure CCS Train B remains operable on Unit 1.

Additionally, this test results in the loss of one train of vital DC when the associated 6.9 kV shutdown board is de-energized. This requires Unit 1 entry into LCO 3.8.4, Conditions A and C (restore in 2 hours2.314815e-5 days 5.555556e-4 hours 3.306878e-6 weeks 7.61e-7 months ). However, the vital AC board and vital battery board will remain energized by the associated vital battery. Therefore, a loss of a vital board is unlikely and is not anticipated.

SR 3.8.1.18 This SR requires verification that the time delay setting for each sequenced load block is within limits. Performance of this test involves individually placing component breakers in test and applying external signals to drive the load sequence relays. There is no impact to the electrical distribution system due to the testing because no loads are connected. However, the LCO Action associated with the component breaker being placed in test is entered during testing of the breaker.

SR 3.8.1.19 and SR 3.8.1.13 SR 3.8.1.19 requires performance of the LOOP / ESF test for each DG. SR 3.8.1.16 requires verification that each DG can synchronize to the offsite power source while loaded with emergency loads upon a simulated restoration of offsite power, transfer loads to the offsite power source, and return to ready-to-load operation. SR 3.8.1.13 requires verification that the DG automatic trips are bypassed on an automatic or emergency start signal. For the DG being tested, the associated 6.9 kV shutdown board is de-energized and load shedding is verified. A manual safety injection actuation signal is initiated. The DG is verified to start, energize the 6.9 kV shutdown board, auto-connect the emergency loads, achieve steady state voltage and frequency, and operate for at least five minutes. In addition, the DG automatic trips are verified to be bypassed.

NRC RAI 2 TS SR 3.8.1.8 Similar to TS 3.8.1 subsections, SR 3.8.1.8 has a note that states that for the 2A-A and 2B-B Shutdown Boards, the Surveillance shall not be performed in MODE 1 or 2. The surveillance requires verification of automatic and manual transfer of each 6.9 kV shutdown board power supply from the normal offsite circuit to each alternate offsite circuit. The staff requested the following information:

1. Clarify when this surveillance will be performed on each of the four shutdown boards that are required when Unit 2 is in Mode 1 or 2.

2. Clarify if each includes shutdown boards 1A-A, 1B-B, 2A-A and 2B-B and how the applicable note for surveillances in Mode 1 or 2 will impact each of the shutdown boards.

CNL-15-094 E-5

Enclosure Responses to NRC Requests For Additional Information - Developmental Revision I Technical Specification Section 3.8 TVAs response cites exemptions granted for preoperational testing and the guidance provided by the Commission in SECY-07-0096 for similarity with WBN Unit 1 and using WBN Unit 1 as the reference basis for the review and licensing of WBN Unit 2. The applicant stated the proposed adoption of the WBN Unit 1 TS 3.8.1 SR Notes, as amended by WBN Unit 1 License Amendment 89, represents conforming changes to the WBN Unit 2 TS 3.8.1 SR Notes.

The staff concludes that the TS requirements for dual unit operation should be reviewed for impact on systems required at both units in all operating modes. Simple adoption of constraints associated with a single unit may lead to non-conservative plant conditions with shared systems.

The staff considers the applicants response to be inadequate and considers this an open item.

TVA Response The test consists of manual and auto transfer of 6.9 kV shutdown boards from the normal offsite power supply to the alternate offsite power supply (C or D CSST). The performance of this test does not render the 6.9 kV Shutdown Board inoperable while transferring power sources from the normal feeder to the alternate feeder then back to the normal feeder. The performance of the surveillance will not initiate a significant perturbation in the electrical distribution system that could challenge a plant safety related system, or challenge steady state conditions to the unit online.

Failure of this surveillance will not challenge or cause an operational transient or challenge to plant safety systems for the unit online. The ability of the 6.9 kV shutdown board to transfer to the DG will not be inhibited should the ability of the electrical board to automatically or manually transfer to the alternate feeder breaker not be functional. The LOOP circuits will still automatically strip the board and allow the DG starting and loading sequence to occur providing power to the ESF systems as designed.

NRC RAI 3 TS SR 3.8.1.13 TS SR 3.8.1.13 is related to verification of each DG's automatic trips that are bypassed on automatic or emergency start signal with the exception of

a. Engine overspeed; and

b. Generator differential current The staff requested clarification for specific contacts that will be tested for normal/emergency mode of operation of the DGs and bypassed during emergency mode of operation in accordance with proposed WBN Unit 2 TS SR 3.8.1.13. In response, TVA provided details on the functional requirements of the associated contacts and stated that WBN procedures periodically verify the capability of the DG trip relays and associated instrumentation to actuate a DG trip. TVA did not provide details on the specific contacts and the frequency of testing associated with TS SR 3.8.1.13.

CNL-15-094 E-6

Enclosure Responses to NRC Requests For Additional Information - Developmental Revision I Technical Specification Section 3.8 The staff considers the applicants response to be inadequate and considers this an open item.

TVA Response Following the discussions of the public meeting held in Rockville, MD on April 30, 2015, it is TVAs understanding that the NRC requests a copy of the maintenance instructions that test the DG engine overspeed and generator differential current trips. Attachment 1 to this enclosure provides a copy of the maintenance instruction for testing the DG engine overspeed trip. In addition, a copy of the preventative maintenance work instruction for performing the DG 1A-A protective relay functional test (including differential current relay test) and a copy of the preventative maintenance work instruction for performing the DG 1A-A differential current relay calibration test. Preventative maintenance work instructions for DGs 1B-B, 2A-A, and 2B-B provide similar testing of the differential current relays associated with those DGs.

NRC RAI 4 TS SR 3.8.1.14 SR 3.8.1.14 has a requirement to test the DG at postulated accident profile and states:

Verify each DG operating at a power factor 0.8 and 0.9 operates for 24 hour2.777778e-4 days 0.00667 hours 3.968254e-5 weeks 9.132e-6 months s:

a. For 2 hours2.314815e-5 days 5.555556e-4 hours 3.306878e-6 weeks 7.61e-7 months loaded 4620 kW and 4840 kW and 3465 kVAR and 3630 kVAR; and

b. For the remaining hours of the test loaded 3960 kW and 4400 kW and 2970 kVAR and 3300 kVAR.

The CLB, as stated in Final Safety Analysis Report, Section 8.1.5.3, indicates the postulated accident loading is equal to or greater than the nominal DG rating. Since the proposed lower limit of test load in TS SR 3.8.1.14 (b), 3960 kW and 2970 kVAR, is less than the nominal rating of the DGs, the staff requested TVA to confirm that the DG testing requirements will envelope the postulated accident loads.

In response to the RAI, TVA stated Worst case loading occurs for a simultaneous loss of offsite power and a loss-of-coolant accident on the unit the diesel is associated with. Adequate margin exists between worst case loading and diesel capacity. To satisfy the continuous rating, it may be necessary for operator action to remove certain loads not required for accident mitigation within 2 hours2.314815e-5 days 5.555556e-4 hours 3.306878e-6 weeks 7.61e-7 months of starting a diesel.

The staff notes that for the DGs to be considered operable, support structures, systems and components (SSC) must be capable of performing the safety functions specified by the design, within the required range of design physical conditions, initiation times, and mission times. In addition, TS operability considerations require that SSCs meet all surveillance requirements.

The satisfactory completion of this SR validates the capability of the DG to perform its required functions as specified in the current licensing basis. The applicant did not confirm that the TS proposed surveillance requirements will envelope the postulated accident loads of the DG.

The staff considers the applicants response to be inadequate and considers this an open item.

Enclosure Responses to NRC Requests For Additional Information - Developmental Revision I Technical Specification Section 3.8 TVA Response WBN Unit 1, UFSAR Section 8.1.5.3, provides WBNs commitment to Regulatory Guide (RG) 1.9, Revision 3. RG 1.9, Revision 3, Regulatory Position C2.2, Test Descriptions, provides the following description of the Endurance and Margin Test:

2.2.9 Endurance and Margin Test: Demonstrate full-load carrying capability at a power factor between 0.8 and 0.9 for an interval of not less than 24 hours2.777778e-4 days 0.00667 hours 3.968254e-5 weeks 9.132e-6 months , of which 2 hours2.314815e-5 days 5.555556e-4 hours 3.306878e-6 weeks 7.61e-7 months are at a load equal to 105 to 110 percent of the continuous rating of the emergency diesel generator, and 22 hours2.546296e-4 days 0.00611 hours 3.637566e-5 weeks 8.371e-6 months are at a load equal to 90 to 100 percent of its continuous rating. Verify that voltage and frequency requirements are maintained.

WBN Unit 1, UFSAR Section 8.1.5.3, annotates that the unit fully conforms with Regulatory Position C2.2.9.

In Reference 3, TVA stated that the continuous rating for each DG is 4400 kW. Therefore, per RG 1.9, Revision 3, Regulatory Position C2.2.9, the 22 hour2.546296e-4 days 0.00611 hours 3.637566e-5 weeks 8.371e-6 months portion of the endurance and margin test is performed at a load equal to at least 90 percent, or, 4400 kW x 0.9 = 3960 kW.

As WBN Unit 1 TS SR 3.8.1.14 requires each DG to be loaded for the remaining hours

[22 hours] at 3960 kW and 4400 kW, this meets RG 1.9, Revision 3, Regulatory Position C2.2.9.

In addition, the current predicted maximum steady-state running loads on the DG for the worst case event are as follows:

0 - 2 hours2.314815e-5 days 5.555556e-4 hours 3.306878e-6 weeks 7.61e-7 months of the DG 1A-A DG 1B-B DG 2A-A DG 2B-B event kW 4313.57 4220.24 4200.69 4332.97 kVA 4969.12 4817.48 4819.42 4990.28 pf 0.868 0.876 0.872 0.868 2 hours2.314815e-5 days 5.555556e-4 hours 3.306878e-6 weeks 7.61e-7 months to end of the

The TS SR 3.8.1.14 requirements to load the DG for 2 hours2.314815e-5 days 5.555556e-4 hours 3.306878e-6 weeks 7.61e-7 months at 4620 to 4840 kW and 3465 to 3630 kVAR, and for the next 22 hours2.546296e-4 days 0.00611 hours 3.637566e-5 weeks 8.371e-6 months at 3960 to 4400 kW and 2970 to 3300 kVAR could result in power factors less than 0.8. Therefore, the surveillance instructions (SI) that implement SR 3.8.1.14 require a narrower band for real power (kW) and reactive power (kVAR) to ensure a power factor greater than 0.8.

Therefore, although not a requirement to meet the acceptance criteria of SR 3.8.1.14 or RG 1.9, Position C2.2.9, the procedural requirements result in DG loading that envelops the predicted accident loads, including the cumulative impacts of DG voltage and frequency at a power factor conservative to the predicted reactive loading on the DG.

NRC RAI 5 TS SR 3.8.4.5 and SR 3.8.4.6 SR 3.8.4.5 and 3.8.4.6 require verification of no visible corrosion at terminals and connectors for the vital and DG batteries. The SR also provides limiting connection resistances for each battery connection to determine battery operability. The SR does not provide an acceptance criterion for the total resistance that should be used for operability determination. The staff requested TVA to confirm that the total battery resistance calculated with each connection at the maximum TS limited value will ensure adequate battery terminal voltage required for safety functions at the end of predicted life. The applicant stated that the WBN has procedures that implement these SRs and that the WBN Unit 2 TSs reflect the same requirements for monitoring and maintaining the batteries that are in the WBN Unit 1 TSs. TVAs response did not clarify the resistance value required to establish battery operability. (This concern is also applicable to SR 3.8.4.9 and SR 3.8.4.10.)

The staff considers the applicants response to be inadequate and considers this an open item.

TVA Response Technical Specification Bases 3.8.4, DC Sources - Operating, LCO section, states that an OPERABLE vital DC electrical power subsystem requires all required batteries and respective chargers to be operating and connected to the associated DC buses.

As stated in the WBN Unit 2 and Unit 1 TS Bases for SR 3.8.4.8, SR 3.8.4.9, and SR 3.8.4.10, visual inspection and resistance measurements of intercell, interrack, intertier, and terminal connections provide an indication of physical damage or abnormal deterioration that could indicate degraded battery condition. In addition, the Bases state that for the purpose of trending, intercell (vital and DG batteries) and intertier (vital and DG batteries) connections are measured from battery post to battery post. Interrack (vital batteries), intertier (DG batteries),

and terminal connections (vital and DG batteries) are measured from terminal lug to battery post.

As described in the TS Bases for SR 3.8.4.13, the battery service test is a test of battery capability, as found, to satisfy the design requirements (battery duty cycle) of the DC electrical power system. The discharge rate and test length should correspond to worst case design duty cycle requirements. This battery service test is used to verify battery operability.

CNL-15-094 E-9

Enclosure Responses to NRC Requests For Additional Information - Developmental Revision I Technical Specification Section 3.8 This understanding is reflected in the NRCs approval of Technical Specifications Task Force (TSTF) Traveler TSTF-500, "DC Electrical Rewrite - Update to TSTF-360," Revision 2 as stated in Federal Register Notice (FRN) dated September 1, 2011 (Reference 5). In the approved TSTF-500, the proposed change relocates the requirements of the following: SR 3.8.4.2 (visual inspection and connection resistance), SR 3.8.4.3 (visual inspection for physical damage), SR 3.8.4.4 (remove visible corrosion and ensure that connections are clean and tight), and SR 3.8.4.5 (verification of connection resistance) to the [new] Battery Monitoring and Maintenance Program.

In the evaluation for removal of the visual inspection from TS, the NRC stated the following:

However, visual inspection of the battery terminals for signs of corrosion to ensure that connections are clean and tight are generally considered a routine preventive maintenance activity. Visual inspection of the battery terminals is an important preventive maintenance practice for maintaining a healthy battery (e.g.,

the early identification and cleaning of battery terminal corrosion can prevent corrosion from spreading between the post and the connector). However, visual inspection of the battery terminals alone does not provide an indication of a batterys capability to perform its design function. Therefore, the NRC staff finds these activities to be preventive maintenance and that the parameters can be adequately controlled in the [new] TS [5.5.17] Battery Monitoring and Maintenance Program.

In the evaluation for removal of the resistance verification from TS, the NRC stated the following:

With regard to the resistance verifications of SR 3.8.4.2 and SR 3.8.4.5, the existing values represent limits at which some action should be taken, not necessarily when the operability of the battery is in question. The plant safety analyses do not assume a specific battery inter-cell connection resistance value, but typically assume that the batteries will supply adequate power. Therefore, the key operability issue is the overall battery connection resistance. Between surveillances, the resistance of each battery inter-cell connection varies independently from all the others. Some of these connection resistance values may be higher or lower than others, and the battery will still be able to perform its function and should not be considered inoperable. Overall connection resistance has a direct impact on operability and is adequately determined by completion of the battery service or modified performance discharge tests. Therefore, these activities are more appropriately controlled under the proposed Battery Monitoring and Maintenance Program and [LICENSEE] provided a justification for the monitoring limit.

TVA is not proposing to adopt TSTF-500 at this time. However, the above discussion from the NRC evaluation regarding the performance of a battery service or performance discharge test to determine battery operability in lieu of using battery connection resistance readings is applicable to WBN.

CNL-15-094 E-10

Enclosure Responses to NRC Requests For Additional Information - Developmental Revision I Technical Specification Section 3.8 Therefore, consistent with the NRC approved TSTF-500, TVA has determined that no new resistance value is required for SR 3.8.4.5, SR 3.8.4.6, SR 3.8.4.9, or SR 3.8.4.10 to establish battery operability, because the battery operability associated with battery resistance is adequately determined by the battery service test or performance discharge test.

NRC RAI 6 TS 3.8.6.3 TS 3.8.6.3 establishes battery operability based on battery cell parameters and average electrolyte temperatures for vital and DG batteries. If the average electrolyte temperature of the representative cells is outside the lower limit (< 60°F for vital batteries and < 50°F for DG batteries), the battery is considered inoperable. The staff requested clarification about the corresponding temperature correction factors that were used for battery sizing criteria in the design calculations. TVA responded that the WBN Unit 2 TSs reflect the same requirements for monitoring and maintaining the batteries that are in the WBN Unit 1 TSs and there are no new requirements imposed on the batteries.

The staff considers the applicants response to be inadequate and considers this an open item.

The DG batteries are required to start the DGs after a four hour SBO event. The TS basis states that the DG battery has sufficient capacity when fully charged to supply required loads for a minimum of 30 minutes following a loss of normal power. The staff requested clarification on the load profile testing that would be used to determine the operability of the DG battery systems.

The TVA response provides details on analytical evaluations performed to demonstrate the adequacy of the DG battery systems and related communications with NRC for WBN2 license application. The applicants response did not confirm that the DG battery systems will be tested using a four hour SBO load profile to demonstrate compliance with requirements of SR 3.8.4.13 and SR 3.8.4.14.

The staff considers the applicants response to be inadequate and considers this an open item.

TVA Response WBN Unit 2 FSAR Section 8.3.1.1, Subheader, Diesel Generator Control Power, states, in part:

The battery has sufficient capacity when fully charged to supply required loads for a minimum of four hours following a loss of normal power. {emphasis added}

Per WBN System Description WB-DC-30-27, AC and DC Control Power Systems - (Unit 1 /

Unit 2), Section 6.2.1, Operating Requirements and System Capacity, the vital batteries have adequate capacity for a period of four hours, without chargers, to provide the necessary DC power to maintain both reactors at hot shutdown, assuming the loss of all AC power sources, i.e., station blackout.

Each test uses the battery discharge unit to discharge the respective DG battery at a 4-hour current rate of 48 amps (corrected for temperature) until battery terminal voltage reaches the minimum design voltage of 105 VDC.

As such, the Background Section of TS Bases 3.8.4 regarding the capacity of the DG batteries is incorrect and is being changed as follows:

125 V Diesel Generator (DG) DC Electrical Power Subsystem Control power for the DGs is provided by four DG battery systems, one per DG.

Each system is comprised of a battery, a battery charger, distribution center, cabling, and cable ways. The DG 125V DC control power and field-flash circuits have power supplied from their respective 125V distribution panel. The normal supply of DC current is from the associated charger. The battery provides control and field-flash power when the charger is unavailable. The charger supplies the normal DC loads, maintains the battery in a fully charged condition, and recharges (480V AC available) the battery while supplying the required loads regardless of the status of the unit. The batteries are physically and electrically independent. The battery has sufficient capacity when fully charged to supply required loads for a minimum of 30 minutes four hours following a loss of normal power. Each battery is normally required to supply loads during the time interval between loss of normal feed to its charger and the receipt of emergency power to the charger from its respective DG.

3.2 The purpose of this PM is to provide instructions for performing functional tests on the protective relays associated with Diesel Generator 1A-A.

3.3 This PM requires advance scheduling with Operations and multiple test personnel will be required. The DG must be removed from service and made inoperative. Minimum configuration requirements are that the air start valves be closed and tagged on a hold order clearance and 6.9kV Shutdown Board 1A-A panel 6 ACB 1912 be in the test position and available to test close and trip.

3.4 This PM involves temporary configuration changes. If work on this PM is interrupted and equipment is left unattended for more than one hour before completion, then place a temporary equipment control tag in accordance with plant administrative instructions to identify each configuration change item or area not returned to normal.

3.5 The acceptability of the PM will be based on the correct performance of all steps.

Any step that fails to respond correctly and cannot be verified shall be evaluated and documented in Section 7.0, and a Service Request (SR) initiated as applicable to correct the failure. The PM performance may proceed even though the specific step related to annunciator and display point responses were not obtained.

3.6 The test personnel performing this PM should be observant of the condition of the protective relays. Any abnormalities such as pitted contacts, broken/cracked covers, cleanliness, etc., should be noted and a work order initiated as applicable to correct the condition.

3.7 This PM may be performed in whole or part depending on the requirements of the work order or the routine schedule. It is acceptable to perform Sections out of sequence. N/A, initial, date, and explain the parts that are not performed.
