TVA Response:

Section 3.2.4.1 of WCAP-15927 describes the RSED design process for custom PC elements and type circuits. The Glossary of Terms in the SPM defines custom PC elements and type circuits as modules.

Therefore, the relationship between WCAP-15927 describing the RSED process as circuits, is defined in the SPM requirements for software module development.

POC Y/N 402, 403 and 404, 3.7.3 Channel Bypass or Removal from Operation 5.5.3 Fault detection and self-diagnostics Computer systems can experience partial failures that can degrade the capabilities of the computer system, but may not be immediately detectable by the system.

Self-diagnostics are one means that can be used to assist in detecting these failures. Fault detection and self-diagnostics requirements are addressed in this sub-clause.

The reliability requirements of the safety system shall be used to establish the need for self-diagnostics. Self diagnostics are not required for systems in which failures can be detected by alternate means in a timely manner. If self-diagnostics are incorporated into the system requirements, these functions shall be subject to the same V&V processes as the safety system functions.

If reliability requirements warrant self-diagnostics, then computer programs shall incorporate functions to detect and report computer system faults and failures in a timely manner. Conversely, self-diagnostic functions shall not adversely affect the ability of the computer system to perform its safety function, or cause spurious actuations of the safety function. A typical set of self-diagnostic functions includes the following:

Memory functionality and integrity tests (e.g.,

PROM checksum and RAM tests)

Computer system instruction set (e.g., calculation tests)

Computer peripheral hardware tests (e.g.,

watchdog timers and keyboards)

Computer architecture support hardware (e.g.,

address lines and shared memory interfaces)

Communication link diagnostics (e.g., CRC checks)

Infrequent communication link failures that do not result in a system failure or a lack of system functionality do not require reporting.

When self-diagnostics are applied, the following self-diagnostic features shall be incorporated into the system design:

a) Self-diagnostics during computer system startup b) Periodic self-diagnostics while the computer system is operating c) Self-diagnostic test failure reporting TVA Response: The requirements for fault detection and self diagnostics and Common Q PAMS system compliance are contained in WNA-LI-00058-WBT-P, Rev. 2, Post-Accident Monitoring System (PAMS)

GA-ESI qualification report 04038903-7SP, Qualification Basis for 04034101 (2-RE-90-271, 272, 273 & 274)

Revision C dated February 22, 2011(Proprietary), submitted on TVA to NRC letter dated February 25, 2011 (Reference 2), section 5.1 states:

GA-ESI has performed the tests on a 2 channel RM-1000 radiation monitoring system the configuration of which is shown in GA-ESI drawing 04509000 System Installation Configuration, RFI/EMI Test, RM-1000 the results of which are issued in GA-ESI report 04038800, RM-1000 EMC Test Report, TVA and 04509050, RM-1000 EMC Test Report.

The equipment tested used an RM-1000 microprocessor radiation monitor Display/Control NIM Bin Assembly, an I-F Converter, line filter, and an RD-23 detector. The monitor system being qualified is the same as the monitor system tested and includes ECO-17656 modifications to ensure EMC compliance.

The 04509050, RM-1000 EMC Test Report was approved by TVA for Sequoyah. The report contains the requested EMI test curves. As a result, it was not resubmitted for the WBN Unit 2 monitors. Attachment 1 contains the TVA approved proprietary version of GA-ESI report 04509050, RM-1000 EMC Test Report. The non-proprietary version and affidavit for withholding will be submitted within two weeks of receipt from GA-ESI.

If there are changes to Controlled Electrically Operated Valves - page 8-9 the analysis then justify those changes based on this BTP.

With regard to safety-related manually controlled, electrically operated valves, the staff asked the applicant to provide (1) an evaluation of all safety-related fluid systems to identify all such valves whose failure (that is, failure to operate on demand or undesired spurious operation) could result in the loss of capability to perform a system safety function (2) a description of the means provided to meet the single-failure criterion in safety-related fluid systems where it is identified that a single failure, as defined above, would result in the loss of capability to perform the system safety function In response, the applicant identified 17 such valves and documented in Section 7.6.6 of the FSAR that the design for these valves consists of modified control circuits. The modified circuit utilizes redundant contacts which are wired before and after each opening and closing coil. Based on its review of the information provided by the applicant, the staff concluded that the above provisions are in accordance with BTP ICSB 18 of SRP Appendix 8-A, with the exception of redundant valve position indication.

Subsequently, the applicant stated that the method of locking out power with the required redundant instrumentation is shown on electrical drawing 45W760-63-2 Based on this drawing, the staff concludes that the design meets the staff's position and is acceptable.

SER Supplement 5 states:

6.3.2 Evaluation, Page 6-3, Supplement 5 In the SER, the staff stated that the applicant will lock out power from certain valves in the emergency core cooling system (ECCS) whose misalignment might affect ECCS effectiveness. Some of these valves would be required to operate following a LOCA, and the manual restoration of power would add to post-accident operational complexity.

By letters dated September 15, 1982, and April 10, 1985, the applicant stated Watts Bar would use modified control circuits for these valves to ensure that no single failure would be able to energize the opening or closing coils of the valve operators. The design uses redundant contacts that are wired before and after each opening and closing coil. In addition, clear protective covers will be attached to the main control board over each respective control switch to prevent inadvertent actuation. As discussed in SER Sections 7.6.4

Accordingly, power will not be locked out from the following valves during operation:

(1) hot-leg injection line valves (2) valves from residual heat removal (RHR) discharge to safety injection (SI) and charging pump suction (3) RHR suction valves from containment sump (4) RHR discharge valves (5) SI pump suction valve from refueling water storage tank (6) SI miniflow valve In addition, the applicant evaluated other valves that may be used for SI miniflow, RHR to SI cross-connect, and SI injection, but for which the consequences of single failure would be acceptable. Power will also not be locked out from these valves. This revision is acceptable to the staff. This review was tracked under TAC 63630.

The design of WBN Unit 2 mirrors the design WBN Unit 1.

As a result, the locked valves for PSB-18 are the same for WBN Unit 2 as for WBN Unit 1 and the list in the Unit 2 FSAR Section 7.6.6 is accurate for Unit 2.

The computer based I&C documents are part of the GA-ESI permanent records equipment needs to and the appropriate GA-ESI records are part of the follow the guidance in permanent TVA WBN Unit 2 quality records. RG 1.209.

(2) The following IEEE 323 section 7.2 documentation requirements for equipment located in a harsh environment are not applicable for equipment located in a mild environment:

k. Aging mechanisms are not required by Reg. Guide 1.209

l. Qualified life determination is not required by Reg.

Guide 1.209

m. Age conditioning test results are not required by Reg. Guide 1.209 The remaining documentation requirements are applicable in whole or in part to the RM-1000 radiation monitors. As described in item 1 above, GA-ESI report 04038903-7SP, Qualification Basis for 04034101-001 (2-RE-90-271, -272, -273 & -274), either contains or references the required documentation.

(3) As stated in Regulatory Guide 1.209, there is no need to establish a qualified life. This is addressed in the next to the last sentence of the second paragraph on page 2 which states: In addition, because of ready accessibility for monitoring and maintenance in mild environments, the need to establish a qualified life does not apply. It is further discussed in the last paragraph on page 6 which states: This guide does not intend to imply that a qualified life should be established for I&C systems in mild environments. Therefore, for the purposes of this guide, qualification is a validation of design to demonstrate that a safety-related computer-based I&C system is capable of performing its safety function under the specified environmental and operational stresses.

Accelerometer ( including the integral insulated hardline cable), Softline cable, and Remote Charge Preamplifiers) were qualified for vibration as addressed in regulatory position C.1.g of RG 1.133, Rev. 1. TVA responded by stating that TVA has reviewed the information provided by Westinghouse describing how the Loose Part Monitoring System (LPMS) sensor is qualified for normal operating conditions provided in Westinghouse letter WBT-D-2782, dated December 17, 2010 (Reference 11) as EICB ( Kemper & Singh) addressed in regulatory position C.1.g of Reg. Guide 1.133 and found it acceptable. Vibration qualification is not applicable to the softline cable. Due to the installation location (junction boxes mounted to the shield or fan room walls) and previous seismic qualification, vibration qualification of the charge converter/preamplifier is not required. This completes the response to this item.

However, the staff still desires further clarification on this response. Specifically, please provide a documented basis that demonstrates the LPMS in-containment equipment is qualified for normal operating conditions (e.g., test results compared to the equipment qualification specification), including vibration qualification.

In response to that request (same letter) TVA provided a description of TVA procedures, BISI software development procedures, and various management measures that will be taken to assure high quality in the design, operation, and maintenance of the SPDS and BISI functions of the ICS. Since the TSC and Nuclear Data Link information originates in the SPDS function of the ICS, are there any aspects of the quality measures that apply to the TSC and NDL features developed as part of quality processes for the ICS that are applicable to the data communications features?
