NRC Request (SSER 23 Appendix HH Item Number 77)
It is unclear to the NRC staff which software V&V documents are applicable to the HRCAR monitors. TVA should clarify which software V&V documents are applicable, in order for the staff to complete its evaluation. (SSER 23, Section 7.5.2.3)
TVA Response to NRC Request The RM-1000 High Range Containment Area Radiation (HRCAR) monitors used by WBN Unit 2 use version 1.2 of the software. The applicable Verification and Validation (V&V) documents are:
a) Software Version 1.0 (initial issue):
General Atomics Electronic Systems, Inc. (GA-ESI) document 04507007-1TR, RM-1000 System Verification Test Results Engineering Report Sequoyah Nuclear Plant Units 1 and 2, Original Release: July, 1999 (verified to be applicable to WBN Unit 2).
This version of the software was never used in any installed monitors and was verified by test. GA-ESI provided the following clarification:... the requirements (test cases) in document 04507006 are covered in document 04507007-1TR. It is on this basis that weve concluded that the version 1.0 software version was validated. Based on review of the document, TVA agrees with the GA-ESI position.
b) Software Version 1.1 GA-ESI document 04508005, RM-1000 Version 1.1 Software Verification Report, January 2002 c) Software Version 1.2 GA-ESI document 04508006, RM-1000 Version 1.2 Software Verification Report, Revision A, April 2008

NRC Request (SSER 23 Appendix HH Item Number 110)
TVA should provide information to the NRC staff describing how the WBN Unit 2 Common Q PAMS design supports periodic testing of the RVLIS function. (SSER 23, Section 7.5.2.2.3.9.2.6)
TVA Response to NRC Request The Common Q PAMS does not have a set of test functions specific to the Reactor Vessel Level Indicating System (RVLIS) functions. Rather it provides a common set of test functions for periodic testing of the PAMS.
The included test functions applicable to periodic testing of RVLIS are:
- 1. Annunciator Test - This test allows verification that each PAMS function alarm actuates the appropriate annunciator window in the MCR.
- 2. Analog Output Test - Allows testing of the analog outputs on the analog output test display. The outputs can be adjusted between 0 and 100% and allows verification of the correct analog output value.
- 3. Input/Output (I/O) Simulator Connection - This function allows the injection of test signals and verification of outputs for the PAMS functions.
The ability to perform a software test of the RVLIS function is not required by WBN Unit 2 Technical Specifications, Revision F. WBN Unit 2 Technical Specification 3.3.3, Post Accident Monitoring (PAM) Instrumentation, requires that a RVLIS channel check be performed on a 31-day interval, and a loop calibration and a Trip Actuating Device Operational Test (TADOT) be performed on an 18-month interval.
Technical Specifications define a channel check as follows:
A CHANNEL CHECK shall be the qualitative assessment, by observation, of channel behavior during operation. This determination shall include, where possible, comparison of the channel indication and status to other indications or status derived from independent instrument channels measuring the same parameter.
Technical Specifications define a TADOT as follows:
A TADOT shall consist of operating the trip actuating device and verifying the OPERABILITY of required alarm, interlock, display, and trip functions. The TADOT shall include adjustment, as necessary, of the trip actuating device so that it actuates at the required setpoint within the required accuracy.
A channel calibration involves testing the loop from the sensor to the display to verify proper operation.
None of the Technical Specification required tests described above require a RVLIS software test function. However, they do fully test the RVLIS function of the PAMS.

Attachment 3 contains Westinghouse Electric Company WNA-CN-00157-WBT-NP, Revision 0, Watts Bar 2 Incore Instrument System (IIS) Signal Processing System (SPS) Isolation Requirements," (Non-Proprietary). contains CAW-11-3215, Application for Withholding Proprietary Information from Public Disclosure, WNA-CN-00157-WBT-P, Revision 0, "Watts Bar 2 Incore Instrument System (IIS) Signal Processing System (SPS) Isolation Requirements, (Proprietary).
The impact of a failed Core Exit Thermocouple (CET) on a PAMS channel is addressed in WNA-AR-00180-WBT-P, Revision 1, Failure Modes and Effects Analysis (FMEA) for the Post Accident Monitoring System, Page 3-6, submitted in TVA to NRC letter dated March 2, 2011 (Reference 1).
- 7.
NRC Request (SSER 24 (Proposed) Appendix HH Item Number 120)
TVA should confirm to the NRC staff that the maximum over-voltage or surge voltage that could affect the system is 264 VAC, assuming that the power supply cable to the SPS cabinet is not routed with other cables greater than 264 Vac. (SSER 24, Section 7.7.1.9.5)
TVA Response to NRC Request TVA Design Criteria Document NPG-DCD-WB-DC-30-27 Revision 33, AC and DC Control Power Systems - (Unit 1 / Unit 2), Section 4.2.2 states that the maximum uninterruptible power supply (UPS) output under fault conditions is 195 Vpeak. During normal operation, the voltage regulation is +/- 2% of 120 Vac.
As documented in Westinghouse Electric Company EQ-QR-39-WBT, Equipment Qualification Summary Report for WINCISE Signal Processing System, Revision 0, (Attachment 5) the SPS cabinets were tested on the ac inputs to withstand a maximum surge of 4000 volts with no loss of function after the surge. A non-proprietary version of EQ-QR-39-WBT and affidavit for withholding will be submitted no later than December 1, 2011.
Based on the above, the system is not expected to see an operating voltage in excess of 195 Vpeak. However, if it does, the system is capable of withstanding a surge up to 4000 Vpeak with no loss of function.

NRC Request (SSER 24 (Proposed) Appendix HH Item Number 122)
TVA should confirm to the NRC staff that different divisions of safety power are supplied to the IIS SPS cabinets, with the power cables routed in separate shielded conduits. (SSER 24 (Proposed), Section 7.7.1.9.5)
TVA Response to NRC Request SPS Cabinets 2-L-201 and 2-L-202 are fed from 120V Vital Instrument Power Board III (Train A) and IV (Train B), respectively. Self-powered detector (SPD) signals coming from incore instrument thimble assemblies (IITAs) shared with Train A/PAM 1 Core Exit Thermocouples (CETs) are connected to 2-L-201 while SPD signals coming from IITAs shared with Train B/PAM 2 CETs are connected to 2-L-202.
These power cables are only routed in separate shielded conduits inside containment.
Outside containment, they are routed in cable trays and/or conduits with cables of the same node voltage (V3) and train designation.
- 9.
NRC Request (SSER 24 (Proposed) Appendix HH Item Number 124)
While the BEACON datalink on the Application server can connect to either BEACON machine, only BEACON A is used for communication. TVA should clarify to the NRC staff whether automatic switchover to the other server is not permitted. (SSER 24 (Proposed),
Section 7.7.1.9.5)
TVA Response to NRC Request Automatic switchover is not possible with the Unit 2 BEACON servers; however, if it were, there is no reason for it not to be permitted. The BEACON servers are not configured in a fully redundant manner and require minimal user intervention to swap over to the redundant backup server. Further information can be found in page 4 of 5 of Attachment 3 in TVA letter dated June 10, 2011, Watts Bar Nuclear Plant (WBN) Unit 2 -
