The PAMS ISG6 compliance matrix supplied as Enclosure 1 to TVA letter dated February 5, 2010 is a first draft of the information needed. The shortcomings of the firs t three lines in the matrix are:
Line 1: Section 11 of the Common Q topical report did include a commercial grade dedication program, but this program was not approved in the associated SE. Westinghouse stated that this was the program and it could now be reviewed. The NRC stated that TVA should identified what they believe was previously reviewed
and approved.
Line 2: TVA stated the D3 analysis was not applicable to PAMS, but provided no justification. The NRC asked for justification since Responder: WEC                        Date: 5/25/10
The PAMS ISG6 compliance matrix supplied as Enclosure 1 to TVA letter dated February 5, 2010 is a first draft of the information needed.

It is TVA's understanding that this comment is focused on the fact that there are documents that NRC has requested that are currently listed as being available for audit at the Westinghouse offices. For those Common Q PAMS documents that are TVA deliverable documents from Westinghouse, TVA has agreed to provide those to NRC. 
Westin ghouse documents that are not deliverable to TVA will be available for audit as stated above. Requirements Traceability Matrix issues will be tracked under NRC RAI Matrix Items 142 (Software Requirements Specification) and 145 (System Design Specification). Commercial Item Dedication issues will be  tracked under NRC RAI Matrix Item 138. This item is considered closed.
TVA Response to Follow-up NRC Request:
WNA-LI-00058-WT-P, Revision 2, "Post-Accident Monitoring System (PAMS) Licensing Technical Report" submitted in TVA Letter to NRC dated December 3, 2010, (Reference 1) contains the following changes to address the NRC requests:
(1) While RSEDs are not specifically mentioned, Section 7 has been revised to be applicable to both hardware and
software which includes the RSEDs. 
(2) Table 6-1 item 15 reference added for WNA-VR-00280-WBT (RESD) 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.

Responder: WEC                        Date: 5/25/10 These sections are descriptive text and not requirements. The next revision of the Watts Bar Unit 2 PAMS System Requirements Specification will remove "shall" from the wording in those sections. A date for completing the next revision of the System Requirements Specification will be provided no later than August 31, 2010.
The System Requirements Specification will be revised by September 30, 2010 and submitted within two of receipt from Westinghouse.
TVA Revised Response
Shall statements within the scope of the System Requirements Specification (SysRS) and System Design Specification (SysDS) were reviewed by Westinghouse. The statements were either relocated to the numbered requirements section or the wording was changed to identify that it was not a requirement. This item is resolved by
submittal of revision 2 of the SysRS and the SysDS (attachments 7 and 8 of TVA Letter to NRC dated 10/25/10).

TVA Response:
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 unchan g ed across pro j ects. Westin ghouse reviewed the generic PAMS requirements and included those requirements that were applicable to WBN Unit 2 PAMS.

TVA Response:
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.

: 24. For Reusable Software Elements, Westinghouse to describe as qualified libraries by 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.

185  EICB (Carte) 7/15/2010 An emphasis is placed on the traceability of requirements in Software 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"    Also the NRC considers that the SRS is the complete set of requirements used for the design of the software, whether it is contained within one document or many. In order to evaluate an SRS against the guidance in the SRP the staff needs access to all the requirements.
References 12, 27, 29, and 31-44 in the Post Accident Monitoring System's Software Requirements Specification are various types of "-Reusable Software Element-". 
These references are used in the body of the SRS, for example:"

They are also included via tables such as found in requirement R7.1.2-1
[The Watts Bar 2 PAMS shall use the application-specific type circuits and custom PC elements listed in Table 7.1-1.]

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.

what changes have been made to this FSAR Section.
Responder: Webb Attachment 5 contains the WBN Unit 2 FSAR markup for Section 7.6.8, "Interlocks for RCS Pressure Control During Low Temperature Operation," showing what was changed between Amendments 95 and 96.
TVA Response to Follow-up NRC Request:
The interlock for the RCS Pressure Control for Unit 2 is implemented differently than Unit 1 implementation. There are no differences between Unit 1 and Unit 2 interlocks, operation of interlocks and operator interface for operation of the RCS Pressure Control. Primary sensing elements and final control elements are identical and operations of these devices are identical. For Unit 2, once si g nals are processed by the Eagle 21 system, interlock implementation is by software modules in the Foxboro I/A Distributed Control System (DCS). Hardware outputs, generated in the DCS, operate the PORVs. The Unit 2 DCS is implemented via EDCRs 52378 and 54504. Section 7.6.8 in Amendment 101 of the WBN Unit 2 FSAR reflects the Unit 2 changes associated with implementation of the DCS.
TVA Response to Second Follow-up NRC Request:

FSAR Sec. NRC POC Issue TVA Response(s) Response Acceptable Y/N Status/ Current Actions Resolution Path RAI No. & Date RAI Resp. Date Comments provide inputs to the Eagle 21 digital process protection system. Eagle 21 provides isolated analog signals to the di g ital process control s ystem. An auctioneer function selects the lowest temperature signal which is then used to calculate an acceptable reference pressure limit (PORV setpoint) considering the plant's allowable pressure and temperature Protection Set III. The calculated reference pressure is compared to the actual RCS pressure monitored by the wide range pressure channel. The auctioneered temperature signal will annunciate a main control room (MCR) alarm whenever the measured temperature approaches, within a predetermined amount, the reference temperature for armin g the system. Similarly, whenever the measured pressure approaches within a predetermined amount of the programmed setpoint, another MCR alarm will be generated. When the measured RCS pressure is equal to or above the programmed setpoint (nominal values), a PORV open signal is initiated and a MCR alarm is actuated. A manually armed permissive allows this actuation signal to control the Train A PORV (PCV-68-340A). The man ually armed permissive also serves to block a spurious PORV opening due to potential instrument failure whenever the RCS temperature is above the arming reference temperature.
The monitored generating station variables that generate the actuation signal for the Train B PORV (PCV-68-334) are processed in a similar manner. The RCS loops 3 and 4 wide range temperature signals and the RCS pressure signal are provided from Protection Set II. Therefore, the generating station variables used for the Train B PORV are derived from a protection set that is independent of the sets from which generating station variables used for the Train A PORV are derived. The wide range temperature auctioneer function and the programmed pressure setpoint calculation for the Train B PORV are performed in a different group of the digital process control system than those for the Train A PORV. Each of these control groups has a fault tolerant, redundant processor pair and redundant power supplies with different power sources.

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 130&#xba;F 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 In response to aquestion about Common Q PAMS equipment qualification, TVA re-evaluated the Control and Aux Instrument Room TID and concluded it to be less than 1x10 3 RAD. 12.

LTR Section 9 evaluates the compliance of the SRS to IEEE 830-1998. There are two issues with this evaluiation: (1) IEEE 830-1998 is not the current SRP acceptance criteria.
IEEE 830-1998 has not been formally endorsed by a regulatory guide.
(2) Westinghouse committed to evaluate the SRS against 830 when the NRC identified several inconsistencies.
Yes ISG-4 is one new criteria, and an evaluation against it has been provided.

The PAMS ISG6 compliance matrix supplied as Enclosure 1 to TVA letter dated February 5, 2010 is a first draft of the information needed. The shortcomings of the firs t three lines in the matrix are:

Line 1: Section 11 of the Common Q topical report did include a commercial grade dedication program, but this program was not approved in the associated SE. Westinghouse stated that this was the program and it could now be reviewed. The NRC stated that TVA should identified what they believe was previously reviewed

and approved.

Line 2: TVA stated the D3 analysis was not applicable to PAMS, but provided no justification. The NRC asked for justification since Responder: WEC Date: 5/25/10

NRC then concluded that TVA should go through and provide a more complete and thorough compliance matrix.

Compliance Matrix."

It is TVA's understanding that this comment is focused on the fact that there are documents that NRC has requested that are currently listed as being available for audit at the Westinghouse offices. For those Common Q PAMS documents that are TVA deliverable documents from Westinghouse, TVA has agreed to provide those to NRC.

Westin ghouse documents that are not deliverable to TVA will be available for audit as stated above. Requirements Traceability Matrix issues will be tracked under NRC RAI Matrix Items 142 (Software Requirements Specification) and 145 (System Design Specification). Commercial Item Dedication issues will be tracked under NRC RAI Matrix Item 138. This item is considered closed.

TVA Response to Follow-up NRC Request:

WNA-LI-00058-WT-P, Revision 2, "Post-Accident Monitoring System (PAMS) Licensing Technical Report" submitted in TVA Letter to NRC dated December 3, 2010, (Reference 1) contains the following changes to address the NRC requests:

(1) While RSEDs are not specifically mentioned, Section 7 has been revised to be applicable to both hardware and

software which includes the RSEDs.

(2) Table 6-1 item 15 reference added for WNA-VR-00280-WBT (RESD) 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.

050 7.5.2 7.5.1 EICB (Carte) 4/8/2010 How should the "shall" statements outside of the bracketed requirements in Common Q requirements documents be interpreted?

Responder: WEC Date: 5/25/10 These sections are descriptive text and not requirements. The next revision of the Watts Bar Unit 2 PAMS System Requirements Specification will remove "shall" from the wording in those sections. A date for completing the next revision of the System Requirements Specification will be provided no later than August 31, 2010.

The System Requirements Specification will be revised by September 30, 2010 and submitted within two of receipt from Westinghouse.

TVA Revised Response

Shall statements within the scope of the System Requirements Specification (SysRS) and System Design Specification (SysDS) were reviewed by Westinghouse. The statements were either relocated to the numbered requirements section or the wording was changed to identify that it was not a requirement. This item is resolved by

submittal of revision 2 of the SysRS and the SysDS (attachments 7 and 8 of TVA Letter to NRC dated 10/25/10).

requirement there?

TVA Response:

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 unchan g ed across pro j ects. Westin ghouse reviewed the generic PAMS requirements and included those requirements that were applicable to WBN Unit 2 PAMS.

TVA Response:

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.

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.

TVA would revise and resubmit the PAMS RTM to address all types of issues identified in the public meeting. (see

ML102920031 Item No 7)

TVA would revise and resubmit

the Software Verification and Validation phase summary report for the requirements phase to document the completion of the requirements

phase review. (see ML102920031 Item No 8) 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?

185 EICB (Carte) 7/15/2010 An emphasis is placed on the traceability of requirements in Software 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" Also the NRC considers that the SRS is the complete set of requirements used for the design of the software, whether it is contained within one document or many. In order to evaluate an SRS against the guidance in the SRP the staff needs access to all the requirements.

References 12, 27, 29, and 31-44 in the Post Accident Monitoring System's Software Requirements Specification are various types of "-Reusable Software Element-".

These references are used in the body of the SRS, for example:"

R5.3.14-2 [The Addressable Constants CRC error signal shall be TRUE when any CAL CRC's respective ERROR terminal = TRUE (WNA-DS-00315-GEN, "Reusable Software Element Document CRC for Calibration Data" [Reference 12]).]

They are also included via tables such as found in requirement R7.1.2-1

[The Watts Bar 2 PAMS shall use the application-specific type circuits and custom PC elements listed in Table 7.1-1.]

Do the referenced reusable software element documents include requirements not explicitly stated in the SRS? If so what is their origin? Responder: WEC Steve Clark to look at how to combine traceability items.

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.

what changes have been made to this FSAR Section.

Responder: Webb Attachment 5 contains the WBN Unit 2 FSAR markup for Section 7.6.8, "Interlocks for RCS Pressure Control During Low Temperature Operation," showing what was changed between Amendments 95 and 96.

TVA Response to Follow-up NRC Request:

The interlock for the RCS Pressure Control for Unit 2 is implemented differently than Unit 1 implementation. There are no differences between Unit 1 and Unit 2 interlocks, operation of interlocks and operator interface for operation of the RCS Pressure Control. Primary sensing elements and final control elements are identical and operations of these devices are identical. For Unit 2, once si g nals are processed by the Eagle 21 system, interlock implementation is by software modules in the Foxboro I/A Distributed Control System (DCS). Hardware outputs, generated in the DCS, operate the PORVs. The Unit 2 DCS is implemented via EDCRs 52378 and 54504. Section 7.6.8 in Amendment 101 of the WBN Unit 2 FSAR reflects the Unit 2 changes associated with implementation of the DCS.

Date Comments provide inputs to the Eagle 21 digital process protection system. Eagle 21 provides isolated analog signals to the di g ital process control s ystem. An auctioneer function selects the lowest temperature signal which is then used to calculate an acceptable reference pressure limit (PORV setpoint) considering the plant's allowable pressure and temperature Protection Set III. The calculated reference pressure is compared to the actual RCS pressure monitored by the wide range pressure channel. The auctioneered temperature signal will annunciate a main control room (MCR) alarm whenever the measured temperature approaches, within a predetermined amount, the reference temperature for armin g the system. Similarly, whenever the measured pressure approaches within a predetermined amount of the programmed setpoint, another MCR alarm will be generated. When the measured RCS pressure is equal to or above the programmed setpoint (nominal values), a PORV open signal is initiated and a MCR alarm is actuated. A manually armed permissive allows this actuation signal to control the Train A PORV (PCV-68-340A). The man ually armed permissive also serves to block a spurious PORV opening due to potential instrument failure whenever the RCS temperature is above the arming reference temperature.

The monitored generating station variables that generate the actuation signal for the Train B PORV (PCV-68-334) are processed in a similar manner. The RCS loops 3 and 4 wide range temperature signals and the RCS pressure signal are provided from Protection Set II. Therefore, the generating station variables used for the Train B PORV are derived from a protection set that is independent of the sets from which generating station variables used for the Train A PORV are derived. The wide range temperature auctioneer function and the programmed pressure setpoint calculation for the Train B PORV are performed in a different group of the digital process control system than those for the Train A PORV. Each of these control groups has a fault tolerant, redundant processor pair and redundant power supplies with different power sources.
