criteria that relate to a Common

'-Appendix 1, "Post Accident Monitoring Systems," provides the functional requirements and

conceptual design approach for

upgrading an existing PAMS based on Common Q components (page 58, Section

4.4.1.1, "Description")-On the basis of the above review, the staff concludes that Appendix 1 does not contain sufficient information to establish the generic acceptability of the

proposed PAMS design (page 56, Section 4.4.1.3, "PAMS Evaluation")-'

The NRC did not approve the proposed PAMS design.

Section 6, "References," and

Section 7, "Codes and

Standards Applicable to the Common Q PAMS," of the PAMS Licensing Technical

Report contain items that are

not the current regulatory criteria.

2. Explain the source(s) of the requirements present in the Post Accident Monitoring System's Software Requirements Specification. To clarify, many documents have requirements that are incorporated by reference into the SRS, but what served to direct the author to include those various documents in the SRS or, if the requirement is based on the System Requirements Specification, what directed the author to include the requirement there?

3. Clarify whether the unnumbered paragraphs in the Post Accident Monitoring System's Software Requirements Specification, such as in the section headings, or are all such sections simply considered to be informative?

Does the same apply to documents referenced by the SRS?

Such as WCAP-16096-NP-A, Rev. 1A, "Software Program Manual for Common Q Systems," which is incorporated by reference in requirement R2.3-2 in the SRS.

R2.3-2 [The PAMS software shall comply with the requirements and guidelines defined in WCAP-16096-NP-A, "Software Program Manual for Common Q Systems" (reference 5).]

If any requirements are expressed in such unnumbered paragraph form instead of individually identified requirements, please list them, describe why they satisfy the fundamental requirement of unambiguity, and describe how they were verified.

4. Are there any sources of requirements in parallel with the Post Accident Monitoring System's Software Requirements Specification? Meaning does the SRS contain, explicitly or by reference, all the requirements that were used in the design phase for the application specific software, or do software design phase activities use requirements found in any other source or document? If so, what are these sources or documents?

TVA Response to 2:

As documented in the RTM, some software requirements are taken from generic documents. The decision to include generic software requirements was to reduce the overall scope for Common Q features that are unchanged across projects. Westinghouse reviewed the generic PAMS requirements and included those requirements that were applicable to WBN Unit 2 PAMS.

Shakun) to Bechtel (Mark S. Clark), RE: December 22 letter review, dated December 17, 2010 (Reference 13)

TVA Response to 3:

Unnumbered paragraphs in the Post Accident Monitoring System's Software Requirements Specification, such as in the section headings, are informative and are not to be interpreted as requirements. All requirements are explicitly

numbered. It depends on the document type. The statement would be true for requirements documents (such as the SysRS or SDS) if they were incorporated by reference. However, for the specific item cited, WCAP-16096-NP-A, Rev. 1A, it does not contain numbered requirements. The requirements contained in this document are contained within the text of the various sections.

19. For Reusable Software Elements, Westinghouse to describe as qualified libraries b y following the SPM and qualified using the Software Elements Test procedure under Appendix B program. Provide a summary of RSEDs generic WCAP. Westinghouse to determine if the WCAP was docketed under the AP1000. RSED concept is not in the SPM. WCAP-15927 AP-1000 does not discuss RCEDs. WCAP process was

acceptable. RSEDs are listed in the SDD References.

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.

WCAP-15927 is on the AP1000 docket.

This report references 04038800, RM-1000 EMC Test Report, TVA, and the results are summarized in 04038903-7S P. 20. N Open Open-NRC Review Due: 2/25/11 349 7.5.2.3 7.5 EICB (Singh) Radiation testing was not considered in any of the test reports as all the equipment has been assumed to be located in nuclear power plant areas with mild environments and radiation dosages less than 1 x 10 3 rads for total integrated dose (TID). However, the radiation monitors and the I/F converters are located in the main control room which is defined as mild environment. For WBN-2 mild environment is defined as room or building zone where (1) the temperature, pressure, or relative humidity resulting from the direct effects of a design basis event (DBE) (e.g., temperature rise due to steam release) are no more severe than those which would occur during an abnormal plant operational condition, (2) the temperature will not exceed 130ºF due to indirect effects of a DBE, (3) the event radiation dose is less than or equal to 1 x 10 4 rads, and (4) the total event plus the 40 year TID (total integrated dose) is less than or equal to 5 x 10 4 rads (reference WB-DC-40-54). TVA to address lack of radiation qualification for

WBN-2. The design criteria provides the criteria for determining what is a mild environment at WBN Unit 2. Calculation WBNAPS4004 "Summar y of Mild Environment Conditions for Watts Bar Nuclear Plant" provides the actual values for each area of the plant. In accordance with Table 1, the Control Room has a 40 year maximum TID of 3.5x10 2 RAD and a maximum integrated accident dose of 710.5 RAD for a maximum TID of 1060.5 RAD.

The accident dose of 710.5 RAD is the dose for a 100 day LOCA at the surface of the HEPA filter in the Mechanical Equipment Room. This is documented in TVA calculation WBNTSR-005, "Dose Due to the Control Building Emergency Air Cleanup Filters" Revision 3. However, on page 25 of WBNTSR-005, the shine from this source into the control room is negligible and is not considered in the dose calculation for the control room.

Calculation WBNAPS3-126, "EQ Dose in the U1/U2 Auxiliar y Instrument Rooms and the Computer Room in the Control Building" Revision 0 documents the environmental qualification (EQ) radiation dose in the control building. A review of this document by the TVA radiation protection engineer determined that the TID including the normal and accident dose values for the control room is less than 1x10 3 RAD. Calculation WBNAPS3-126, will be revised to include the control room b y Jul y 1, 2011. Since the control room TID has been determined to be less than 1x10 3 RAD, radiation qualification of the RM-1000.

As documented in Attachment 12, "WCAP 13869 Revision 2 Change Analysis", to TVA to NRC letter dated October 29, 2010, the differences are all administrative clarifications.

No. 36 344 7.6.6 ? Eicg(Garg) Unit 1 SE discussed in Section 7.6.5, "Valve Power Lockout". There is no section in FSAR which provides discussion on this subject. SE section discusses compliance with PSB-18. Provide a discussion which can be used by the staff to determine similar conclusion as Unit 1 and if the design is similar to Unit 1 then make a statement to that effect. Also provide the list of the valves where power lockout during normal reactor operation is utilized for valves whose inadvertent operation could affect plant safety. How do we meet the PSB? (a) In accordance with0PDP-6, "Locked Valve/Breaker Program," Revision 1 (Attachment 25), valves locked by design are shown on design output documents (flow diagrams, system descriptions, etc.). As documented in 0PDP-6, valves are locked for multiple reasons. It is anticipated that many of the valves that were locked to provide positive isolation between Unit 1 and Unit 2 will not be locked when Unit 2 becomes operational and will be removed from the locked valve program. At the same time, Unit 1 valves locked for operational/Appendix R/Single Failure criteria will result in the corresponding Unit 2 valves being locked.

(b) The list of valves locked by design is contained in 0-PI-OPS-17.0, "18 Month Locked Valve Verification," Revision 44 (Attachment 21). Valves locked out by opening the associated circuit breaker are listed in 0-PI-OPS-17.1, "18 Month Locked Breaker Verification," Revision 14 (Attachment 24).

TVA Response to Follow Up NRC Question SER Supplement 0, Section 8.3.1.8 states:

8.3.1.8 Application of the Single Failure Criterion to Manually Controlled Electrically Operated Valves - page 8-9 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

includes MOV, SOV and those valves operated indirectly by an electrical device, e.g.an air operated valves whose air

supply is controlled by an electrical solenoid valves.

FSAR Section 7.6.6 addresses only MOVs. If TVA has done an analysis to demonstrate compliance with the guidance of this BTP for Unit 1 and this analysis does not change for Unit 2 for other valves than TVA shouls make a statement to that effect. If there are changes to the analysis then justify those changes based on this BTP.

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.

Subsequentl y, the applicant stated that the method of lockin g 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 sin gle 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 and 8.3.1.8, the staff found this design acceptable. 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

Date Comments (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.

345 7.5.2.3 7.5 EICB (Singh) Provide the normal temperatures and expected periods of high/low temperature excursions to assess aging requirements. TVA to further clarify if 86ºF for 40 years was used as the qualification requirement for aging tests. This has been stated in some of the subsections under section 4.2 of the 04508905-QR report but the

rationale for using 86ºF (includes an internal temperature rise of 18ºF) for 40 years has not been justified in the 04508905-QR report or the supplement reports.

TVA to provide the rationale for this acceptance criteria for WBN-2.

Check on verification of the 40 y ear life of the rad monitors. How is this explained.

RM-1000 in a NIM Bin was Tested at 39°F for 72 Hrs and Tested at 131°F for 72 Hrs per Section 4.2.6 of 04508905-QR. This is stated in document 04038903-7SP, Section 2.1.

The ambient temperature used for aging was 86°F(30°C).

The NIM Bin has perforated holes in top and bottom covers

and has an average internal temperature rise of approximately 18 °F due to natural air convection. So the average internal temperature used for aging was 104°F (40°C) In accordance with Attachment 8, 04038903-QSR, "Qualification Summary Report for Watts Bar Nuclear Plant Unit 2 Replacement Radiation Monitors" Section 3.2, the aging is to an ambient equivalent condition of 104°F which is based on an 86°F average ambient temperature of the environment and an enclosure temperature rise of 18°F.

IEEE Std 1205-2000, Table D.8 shows that the upper bounding temperature is 104°F for all plant areas except the reactor building. The intent in qualifying the part for 40 years is to identify each component's failure mechanisms and to determine whether 40 years 1 of aging has a significant effect of these failure mechanisms.

1The design life goal for most Class 1E equipment is 40 years, but for most electronic assemblies 20 years, or less, is more realistic. Because of rapidly changing technologies, replacement components sometimes become unavailable in a relatively short period of time.

NNC 8/12/10:

It is not quite enough to provide all of the documents requested. There are two possible routes to review that the NRC can undertake: (1) follow ISG6, and (2) follow the CQ SPM. The TVA response that was originally pursued was to follow ISG6, but some of the compliance items for ISG6 were addressed by referencing the SPM. The NRC approved the CQ TR and associated SPM; it may be more appropriate to review the WBN2 PAMS application to for adherence to the SPM that to ISG6. In either path chosen, the applicant should provide documents and a justification for the acceptability of any deviation from the path chosen. For example, it appears that the Westinghouse's CDIs are commercial grade dedication plans, but Westinghouse maintains that they are commercial grade dedication reports; this apparent deviation should be justified or explained.

183 EICB (Carte) 7/15/2010

An emphasis is placed on traceability in System Requirements Specifications in the SRP, in the unmodified IEEE std 830-1993, and even more so given the modifications to the standard listed in Regulatory Guide 1.172, which breaks with typical NRC use of the word "should" to say "Each identifiable requirement in an SRS

must be traceable backwards to the system requirements and the design bases or regulatory requirements that is satisfies" On page 1-2 of the Post Accident Monitoring System's Software Requirements Specification in the background section, is the sentence "Those sections of the above references that require modification from the generic PAMS are defined in the document" referring purely to the changes from WNA-DS-01617-WBT "Post Accident Monitoring System-System Requirements Specification" or is it saying that there are additional changes beyond those and that the SRS defines them?

If there are additional changes, what is their origin?

V&V, configuration management, and QA shall be required for test and calibration functions on separate computers (e.g., test and calibration computer) that provide the sole verification of test and calibration data. V&V, configuration management, and QA shall be required when the test and calibration function is

inherent to the computer that is part of the safety system.

V&V, configuration management, and QA are not required when the test and calibration function is resident on a separate computer and does not provide the sole verification of test and calibration data for the computer that is part of the safety 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.
