Enclosure Response to Request for Additional Information Regarding Watts Bar Nuclear Plant, Unit 2 License Amendment Request for One-Time Extension of Technical Specification Surveillance Requirements Group 2 (LAR Encl. 1 Attachments 5, 6, 7, 9, 12, 13, 14, 15, 16, and 17) (CAC No. MF8895)

Nuclear Regulatory Commission (NRC) Introduction By letter dated November 23, 2016, (Agencywide Documents Access and Management System (ADAMS) Accession No. ML16333A250), Tennessee Valley Authority (TVA),

submitted a license amendment request (LAR) for Watts Bar Nuclear Plant, Unit 2. The LAR proposes to revise Technical Specification (TS) Surveillance Requirement (SR) 3.0.2 to extend, on a one-time basis, specific SRs that are normally performed on an 18-month frequency in conjunction with a refueling outage. Of the 52 SRs in the LAR, the staff is currently reviewing the 33 SRs represented in attachments 5, 6, 7, 9, 12, 13, 14, 15, 16, and 17, to Enclosure 1 of the LAR.

The staff has identified areas where additional information is needed to complete its technical review and make a regulatory finding regarding this LAR in accordance with the requirements of Title 10 of the Code of Federal Regulations (10 CFR) 50.36, which sets forth the regulatory requirements for the content of the TSs. Specifically,10 CFR 50.36(c)(3) requires SRs to be included in the TS, and states that SRs are requirements relating to test, calibration, or inspection to assure that the necessary quality of systems and components is maintained, that facility operation will be within safety limits, and that the limiting conditions for operation will be met. The following 5 requests for additional information (RAIs) are from the NRC/NRR Balance of Plant and Instrumentation & Controls Branches.

NRC RAI-MF8895-SBPB-01 In attachment 15 to Enclosure 1 of the November 23, 2016, LAR, the section titled, Review of Operating Experience states:

On June 5, 2016, an automatic SI occurred. This functionally tested the automatic actuation logic for ECCS, CIVs, CSS, EGTS, CCS, and ERCW systems. All safety systems functioned as designed and previously evaluated in the UFSAR.

This functionally tested the automatic actuation logic for the ECCS SR via the slave relays K603, K604, and K608. The K603 and K604 relays provided the automatic alignment of the ECCS valves. K608 provided the automatic start signal to the ECCS pumps. ECCS responded as expected to the automatic SI signal. The automatic actuation signal to ECCS was functionally tested on June 5, 2016. All other functions of the circuit were tested and were within frequency, which includes the end device operation of ECCS.

Did the June 5, 2016, automatic Safety Injection (SI) also result in pumps/fans starting in the Containment Spray System (CSS), Emergency Gas Treatment System (EGTS), Component Cooling System (CCS) and essential raw cooling water (ERCW) systems, and cause valves and dampers in these systems to reposition, and containment isolation valves (CIVs) in other systems to reposition? If so, which components were observed to respond properly and which were already operating or in their safety position such that the automatic SI did not yield much in the way of verification for those components and associated circuitry that performing the SR implementing procedures would obtain?

CNL-17-066 E1 of 31

Enclosure TVA Response:

The requested information is provided in Table 1 to this enclosure, which lists the components of the systems that actuated during the June 5, 2016, automatic SI, their pre-auto SI state and their state following the SI. Table 1 also identifies the components that were in the safety position/status and could not be verified for proper SI actuation (see Note 2 to Table 1). The components listed in Table 1 that were able to be verified, were verified by using computer points showing a change in state from their pre-SI position to their post-SI position.

As shown in Table 1:

  • The EGTS fans did start during the June 5, 2016, automatic SI and some valves realigned.
  • The CCS pumps not already running did start during the June 5, 2016, automatic SI.
  • The ERCW pumps aligned to start automatically started upon receipt of the June 5, 2016, SI signal, and some essential valves aligned to their post-accident positions (see Table 1, SRs 3.7.8.2 and 3.7.8.3).
  • Some CIVs pre-auto and SI actuation condition could be verified (see Table 1, SR 3.6.3.6). The CIVs for the EGTS, CCS, and ERCW did not change state as result of the June 5, 2016, SI signal.

Furthermore, while developing this RAI response, TVA has determined that the quoted paragraph in the RAI from Attachment 15 to Enclosure 1 of the referenced letter regarding the June 5, 2016, automatic SI should have not referred to the CSS. The CSS receives a containment spray engineered safety feature actuation system signal, but not an SI signal.

NRC RAI-MF8895-EICB-1 In Attachment 6 to Enclosure 1 of the LAR, the licensee identified SR 3.3.2.2 and SR 3.3.2.3, as providing alternate means of partially satisfying SR 3.3.2.5 and SR 3.3.2.7.

SR 3.3.2.2 requires an actuation logic test to be performed on the engineered safety feature actuation system (ESFAS) instrumentation. The WBN Unit 2 SR 3.3.2.2 Bases state, "The train being tested is placed in the bypass condition, thus preventing inadvertent actuation.

Through the semiautomatic tester, all possible logic combinations, with and without applicable permissives, are tested for each protection function. In addition, the master relay coil is pulse tested for continuity." SR 3.3.2.3 requires a master relay test to be performed on the ESFAS instrumentation. The WBN Unit 2 SR 3.3.2.3 Bases state, "The MASTER RELAY TEST is the energizing of the master relay, verifying contact operation and a low voltage continuity check of the slave relay coil. Upon master relay contact operation, a low voltage is injected to the slave relay coil. This voltage is insufficient to pick up the slave relay, but large enough to demonstrate signal path continuity." Neither SR 3.3.2.2 nor SR 3.3.2.3 actually exercise the slave relays.

a. Please provide the rationale as to why the continuity check satisfies the SR 3.3.2.5 requirement to perform an actuation logic test of the slave relays. Specifically, please explain how the slave relay coil is powered on or off while simultaneously monitoring the circuit that is driven by the slave relay contacts.

CNL-17-066 E2 of 31

Enclosure

b. Please explain what specific parameters are being monitored in the slave relay output circuit when the slave relay coil is being powered on or off. Please explain how the change of state of the output relay in response to application of power to the slave relay coil is verified.
c. Please provide equivalent Unit 1 and Unit 2 data, including failure date, for the testing performed as part of SR 3.3.2.5 and SR 3.3.2.7 TVA Response
a. The testing of the Master relays also includes a continuity check of the slave relay coil to verify the master relay contact has actuated. This testing energizes the slave relay coil with 15 volts DC vice the normal coil pickup 120 volts AC to prevent component actuation. This testing does not satisfy SR 3.3.2.5, but does confirm the slave relay coil has not open-circuited and provides some measure that the slave relay could actuate.

Additionally, TVA performs a continuity check of the slave relay coil on a quarterly basis in accordance with SR 3.3.2.3. Therefore, TVA is confident that the slave relays will remain operable during the extended surveillance period.

b. As noted in the response to item a. above, for surveillance testing that satisfies SR 3.3.2.5, the slave relay is actuated and slave relay contact operation is verified.

While the change of state of the output relay is not specifically verified, as noted in the response to item a. above, the testing of the Master relays also includes a continuity check of the slave relay coil to verify the master relay contact has actuated.

c. The requested information for the associated functions of the Watts Bar Nuclear Plant (WBN) TS SR 3.3.2.5 and SR 3.3.2.7 (see Attachment 6 to Enclosure 1 of the referenced letter) is provided in Tables 2 and 3 to this enclosure, respectively. As shown in Table 2, there were no failures for the performances of SR 3.3.2.5. As shown in Table 3, there were three documented failures for SR 3.3.2.7, but in each case, the associated components were retested satisfactorily.

NRC RAI-MF8895-EICB-2 In Attachment 7 to Enclosure 1 of the LAR, the licensee stated that no additional testing has been performed since the surveillance activity for SR 3.3.2.8, functions 1.a, 2.a, 3.a.1, and 3.b.1 was last performed. The licensee identified the performance of SR 3.3.2.2 and SR 3.3.2.3 as providing further assurance of the operability of the ESFAS instrumentation.

SR 3.3.2.2 requires an actuation logic test to be performed on the ESFAS instrumentation every 92 days on a staggered test basis, and SR 3.3.2.3 requires a master relay test to be performed on the ESFAS instrumentation every 92 days on a staggered test basis.

a. Please identify if the manual initiation of the hand switches is tested under SR 3.3.2.2 or SR 3.3.2.3.
b. If the hand switches are not part of the test performed under SR 3.3.2.2 or SR 3.3.2.3, please identify the last time the hand switches for SR 3.3.2.8, functions 1.a, 2.a, 3.a.1, and 3.b.1 were exercised under test or operational conditions, where the results of the hand switch changing state were observable.

CNL-17-066 E3 of 31

Enclosure TVA Response

a. The manual initiation of the hand switches is not tested under SR 3.3.2.2 or SR 3.3.2.3.

As noted in the Attachment 7 to Enclosure 1 of the referenced letter, further assurance of the operability of the ESFAS instrumentation is demonstrated through the performance of SRs 3.3.2.2 and 3.3.2.3. SR 3.3.2.2 requires an actuation logic test to be performed on the ESFAS instrumentation every 92 days on a staggered test basis.

SR 3.3.2.3 requires a master relay test to be performed on the ESFAS instrumentation every 92 days on a staggered test basis.

b. As noted in Attachment 7 to Enclosure 1 of the referenced letter, SR 3.3.2.8, functions 1.a, 2.a, 3.a.1, and 3.b.1 apply to the following hand switches:
  • WBN-2-HS-63-133A - SI Actuate
  • WBN-2-HS-63-133B - SI Actuate
  • WBN-2-HS-30-64A - Phase B & CVI
  • WBN-2-HS-30-64B - Phase B & CVI
  • WBN-2-HS-30-68A - Phase B & CVI
  • WBN-2-HS-30-68B - Phase B & CVI
  • WBN-2-HS-30-63A - Phase A & CVI
  • WBN-2-HS-30-63B - Phase A & CVI The testing of WBN-2-HS-63-133A and WBN-2-HS-63-133B is performed using 0-SI-82-5, 18 Month Loss Of Offsite Power With Safety Injection - DG 2A-A, and 0-SI-82-6, 18 Month Loss Of Offsite Power With Safety Injection - DG 2B-B. 0-SI-82-5 was last performed satisfactorily on September 16, 2015, and 0-SI-82-6 was last performed satisfactorily on September 7, 2015.

The testing of WBN-2-HS-30-64A, WBN-2-HS-30-64B, WBN-2-HS-30-68A, WBN-2-HS-30-68B, WBN-2-HS-30-63A, and WBN-2-HS-30-63B is performed using 2-SI-99-5, 18 Month Trip Actuating Device Operational Test for Phase A, Phase B, Containment Vent, and Containment Spray Manual Initiation. 2-SI-99-5 was last performed satisfactorily on October 7, 2015.

RAI-MF8895-EICB-3 In Attachment 9 to Enclosure 1 of the LAR the licensee identified the level transmitters are the same make and model (Barton 764) for both units, and two of the three wide range pressure transmitters are the same make and model (Barton 763) for both units. The third pressure transmitter is a Weed transmitter with manufacturers drift specification of 0.4% of the range (6000 psig) over 24 months (i.e., a drift of 24 psig).

a. For the Barton 764 level transmitters and the Barton 763 pressure transmitters, please provide equivalent Unit 1 calibration results data as well as channel check results for the previous 2 years.
b. Please identify any verification performed to confirm the manufacturers drift values for the Weed transmitter.

CNL-17-066 E4 of 31

Enclosure

c. Please include the design basis as-found and as-left tolerances for the transmitters associated with these SRs in your responses to a. and b. above.

TVA Response

a. The WBN Unit 1 channel calibration data for at least the previous two years for the Reactor Vessel Level Instrumentation System (RVLIS) Barton 764 level transmitters and Barton 763 pressure transmitters (SR 3.3.3.2, Functions 5 and 6) is provided in Tables 4 and 5. As shown in Tables 4 and 5, the as-left data was either the same as the as-found or was within their tolerance criteria.

The WBN Unit 1 channel checks for the RVLIS Barton 764 level transmitters and Barton 763 pressure transmitters (SR 3.3.3.1, Functions 5 and 6) are performed in accordance with 1-SI-0-4, Monthly Surveillances. The dates that the WBN Unit 1 channel checks were performed for these components for at least the previous two years is provided in Table 6. The monthly channel check is performed by recording the readings for each instrument for the SR function, comparing the lowest reading to the highest reading, and determining if the difference between the lowest reading and the highest reading is within the maximum channel deviation (MCD). If any channel deviation exceeds 80% of the MCD limit, the Unit Supervisor is notified so that the condition can be evaluated and appropriate corrective actions taken. The channel checks performed in Table 6 were all completed satisfactorily.

b. TVA has not verified the manufacturers drift data for the Weed transmitter. Drift tolerances from the manufacturer are not normally verified for any instrument. The drift tolerances are used in establishing design requirements accounting for drift. If repeated out of tolerances occur, the instrument would be reviewed for acceptability of drift tolerances and specific instrument application in accordance with the TVA corrective action program. Further assurance of the operability of the Weed transmitters is provided by the performance of the WBN Unit 2 channel checks (SR 3.3.3.1, Functions 5 and 6) in accordance with 2-SI-0-4, Monthly Surveillances. The dates that the WBN Unit 2 channel checks were performed for these components is provided in Table 6. The channel checks performed in Table 6 were all completed satisfactorily.
c. The as-found and as-left tolerances vary for each of the transmitters associated with SR 3.3.3.1, Functions 5 and 6 are defined in the individual SIs as shown in Tables 4, 5, 7, and 8 to this enclosure. As noted in the response to item a. above, for WBN Unit 1, as shown in Tables 4 and 5, the as-left data was either the same as the as-found or was within their tolerance criteria. A review of the historical performances for each of the associated surveillance instructions (SIs) for WBN Unit 2 SR 3.3.3.2, Functions 5 and 6 is provided in Tables 7 and 8 to this enclosure, respectively. As shown in Tables 7 and 8, the as-left data was either the same as the as-found or was within their tolerance criteria.

CNL-17-066 E5 of 31

Enclosure RAI-MF8895-EICB-4 In Attachment 14 to Enclosure 1 of the LAR the licensee did not identify any operating experience applicable to SR 3.4.12.8, or any other testing as providing alternate means of partially satisfying SR 3.4.12.8.

Please provide equivalent Unit 1 calibration data for the testing performed as part of this surveillance. Please include the as-found and as-left tolerances.

TVA Response A review of the last four performances for each of the SIs for WBN Unit 1 SR 3.4.12.8 was performed. The as-found and as-left tolerances vary for each of the transmitters associated with SR 3.4.12.8 and are defined in the individual SIs as shown in Table 9 to this enclosure.

As shown in Table 9 to this enclosure, the as-left data was either the same as the as-found or was within their tolerance criteria.
