A CQ PAMS ISG6 compliance matrix was docketed on: (1)

Agenda for Weekly Telecom with TVA (I&C Chapter 7 only) radD9A82.docx Open Items to be Resolved for SER Approval No. SE Sec. FSAR Sec. NRC POC Issue TVA Response(s) Response Acceptable Y/N Status/ Current Actions Resolution Path RAI No. & Date RAI Resp. Date Comments 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 SRP Chapter 7.5 identified SRM to SECV-93-087 Item II.Q as being SRP acceptance criteria for PAMS.

Line 3: TVA identified that the Design report for computer integrity was completed as part of the common Q topical report. The NRC noted that this report is applicable for a system in a plant, and the CQ topical report did no specifically address this PAMS system at

Watts Bar Unit 2.

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

The PAMS ISG6 compliance matrix supplied as Enclosure 1 to TVA letter dated February 5, 2010 is a first draft of the information needed.

By letter dated April 8, 2010 TVA provided the PAMS Licensing Technical Report provided additional information.

contains the revised Common Q PAMS ISG-6 Compliance Matrix, dated June 11, 2010, that addresses these items (Reference 13).

By letter Dated June 18, 2010 (see Attachment 3) TVA provided a table, "Watts Bar 2 - Common Q PAMS ISG-6 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)

TVA Response to Second Follow-up NRC Request:

The NRC audited the Westinghouse commercial item dedication process for both hardware and software during the week of February 28 to March 4, 2011. The audif found the processes acceptable. Westinghouse and TVA previously agreed to provide additional information to address this item in Revision 3 of the Licensing Technical Report.

contains WNA-LI-00058-WBT-P, "Post-Accident Monitoring System (PAMS) Licensing Technical Report," Revision 3, dated March 2011 (proprietary). contains WNA-LI-00058-WBT-NP, "Post-Accident Monitoring System (PAMS) Licensing Technical Pending Submittal of Revision 3 of the Licensing Technical Report due 3/29/11.

Revised response included in

letter dated 12/22/10.

Response is included in letter

dated 10/5/10.

Revised compliance matrix is unacceptable.

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. Due 3/29/11 NNC 2/2/11:

Issues with Common Q TR &

SPM compliance were discussed in the weekl y public meetings. Westinghouse to perform Common Q TR

& SPM compliance self assessment; his will be discussed in detail on the next audit. Item No. 2 TVA Letter dated 5/12/10 TVA Letter dated

6/18/10 TVA Letter dated

10/5/10 February, 5 12010, (2) March 12, 2010, & (3) June 18, 2010. The staff has expressed issued with all of these compliance evaluations. The staff is still

waiting for a good compliance evaluation.

NNC 11/23/10: WNA-LI-00058-WT-P Rev. 1 Section 7 does not include the RSED documents, and it should. Table 6-1 Item No. 15 should also include the RSED RTMs.

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?

5. 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:"

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.

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.

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 item is used to track all traceability issues with the System Design Specification (SDS).

At the September 15 public meeting in Rockville, the following actions were agreed to. These items partially address the traceability concerns with the System Design Specification. This item will be updated with the results of the September 20 and 21 Commercial Grade Dedication and SDS RTM audit.

1. Westinghouse will perform completed a review of the Requirements Traceability Matrix(RT), using the issues identified at the 9/15 public meeting as a guide (documented below) and update the RTM as required.

2. Some hardware requirements are contained in the SRS instead of the System Design Specification (SDS). These will be removed from the SRS and incorporated into the next

revision of the SDS.

3. 25 issues identified by V&V where some requirements have not been included in the SDS (14) and SRS (11) at the revisions reviewed by V&V. Have these been addressed?

Yes. The next revisions of the SDS and SRS address these issues. 4. TVA will update the Procurement Requisition Resolution Matrix and submit it to show how the Common Q PAMS design meets the contract requirements.

5. The next issue of the IV&V report will include the Requirements phase review of the RTM and a partial review

for the Design phase.

6. Westinghouse to provide the generic AC160 and flat panel specifications.

7. Westinghouse and TVA to develop a schedule of licensing document submittals that can be met by the project team.

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

desi gn 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

S ystem's Software Requirements Specification are various t ypes 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

Summary provided in Licensing Technical Report R2 has been reviewed and found to be unacceptable.

LTR Section 9 evaluates the compliance of the SRS to IEEE

830-1998. There are two issues with this evaluation: (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.

In addition, LTR Rev. 2 Section

13 states: "The applicable NRC

regulatory guides, IEEE and EPRI industry standards fo the common Q PAMS are shown

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)

The design bases for the response to feedwater break inside containment, as documented in Chapter 15 of the WBN Unit

2 FSAR, is the same for WBN Unit 1. Since WBN Unit 2 is required to match the WBN Unit 1 licensing basis to the extent practical, the decision was made to revise the WBN Unit 2 FSAR to agree with the WBN Unit 1 FSAR which uses Revision 1. Revised Response is included in letter dated 10/29/10 The staff is confused with the response since both units have

reference leg not insulated Rev 2 should apply to Unit 1 also and there should be no

difference between Unit 1 and 2 Need to provide additional info on why Rev. 1 is acceptable for both units.

differences between WCAP-13869 rev.1 and rev2., but staff agree

that rev1 and change analysis could be basis for acceptance for both Watts Bar units.

GA-ESI submitted their commercial grade dedication procedure (OP-7.3-240, "Safety-Related Commercial Grade Item Parts Acceptance," Revision H) to engineering for review. Engineering review of the procedure found that the procedure, Section 5, did not require multiple dedication methods for complex CGI or CGI used in digital safety systems. As a result, it was determined that the GA-ESI program did not meet the requirements of NUREG-800, Section 7.0A, Revision 5.

A discussion with GA-ESI found that while not required by procedure, GA-ESI does perform vendor surveys as required by Method 2 of NP-5652. The surveys are done based on prudent business practices. Based on this discussion, GA-ESI agreed to review the CGI used in the WBN Unit 2 digital safety-related monitors to determine if they had been dedicated by more than one method.

The review of the CGI used in the WBN Unit 2 digital safety-related monitors determined that all CGI had been dedicated using Method 1 of EPRI guideline NP-5652. However, in the sample of items reviewed, there were CGI that were dedicated usin g a sin gle method. Based on the results of the engineering procedure review and the results of the GA-ESI CGI review, Service Request 346896 was initiated to document the condition and to place the monitors in "Conditional Release" status.

Based on the results of the previous reviews, GA-ESI agreed to the following plan of action to resolve the CGD issue:

1. GA-ESI shall revise its commercial grade dedication procedure (OP-7.3-240) to require multiple dedication methods be utilized for complex commercial grade items and commercial grade items for digital safety class systems. The evidence that this has been

Please provide an explanation regarding why this is acceptable.

Attachment 2 of this letter provides five pages from the first seismic test (Wyle Test report 41991) from GA-ESI report 04508903-1TR, submitted in response to OI-357 on TVA to NRC letter dated March 31, 2011 (Reference 1). The following discussion refers to these pages.

Wyle test report 41991 provided the seismic test results for two RM-1000 monitors (one area monitor and one process monitor) and one I/F converter. During the test, the RM-1000 monitor confi g ured as an area monitor was damaged due to the test table impacting its mechanical

stop (see page 4 of Wyle Test Report 41991 attached).

This first test was completed for the RM-1000 monitor configured as a process monitor and the I/F converter.

A second seismic test for the RM-1000 monitor configured as an area monitor and two I/F converters (Wyle Test Report 41991-1) is also included in 04508903-1TR. The RM-1000 monitor used in this second test was the same RM-1000 process monitor used in the first seismic test reconfigured (switch in

application t ype 1 mode) as an area monitor. One of the I/F converters tested was the same I/F converter tested in the first seismic test. This second test was performed to complete the testing which could not be performed during the first seismic test due to the damage to the RM-1000 area monitor and the loss of the high voltage power supply to the I/F converter that occurred during the first seismic test. None of the TRS plots in this second seismic test report 41991-1 were below the RRS. General Atomics "Qualification Test Report for RM-1000

Processor Module and Current-To-Frequency Converter" (04508905-QR) refers to both Wyle Reports 41991 and 41991-1 included in report 04508903-1TR. It is recognized that the five TRS Plots versus the RRS

where the TRS were below the RRS is an exceedance that must be justified. From Wyle report 41991 it can be determined that these five TRS versus RRS plots are for the seismic response in the front to back panel direction.

The RRS used in the Wyle test reports envelopes the

TVA standard RRS shown in Fig 3.1 of TVA Standard Specification CEB-SS-5.10, "For Seismic Qualification of Electrical, Mechanical and I&C Devices," submitted on TVA to NRC letter dated February 25, 2011, (Reference

For specific cases when required the actual in panel RRS can be developed. Calculation WCG-ACQ-0766, "In-Cabinet Required Response Spectra for RM-1000 Radiation Monitors in MCR Panel 2-M-30," Revision 0, (Attachment 3) has been issued to generate the 5% RRS for these safety related RM-1000 monitors, I/F converters and NIM bins for the WBN2 panel (2-M-30) where they will be installed. As can be seen from the RRS plots in calculation WCG-ACQ-0766 the front to back 5% RRS broad band peak is 9.76 g which is lower than the front to back 5% TRS shown in

the subject five (5) plots.

Please provide an explanation regarding why this is acceptable

. The display module for the RM-1000 monitors procured for WBN2 differs from that used in previous RM-1000 qualification tests. The seismic qualification basis for the WBN2 display module is established by similarity to the display module used in RM-2000 monitor qualification tests shown on page 5-4 and 5-5 of 04508905-1SP (pages attached). The basis for the similarity discussion is provided on pages 5-2 and 5-3 of 04508905-1SP. The TRS non-exceedance at

approximately 6-7 Hz shown on page 5-5 is not applicable to WBN2 since the RRS shown on that figure is not used for WBN2 qualification. The correct

comparison for WBN2 would be the TVA standard RRS shown in Fig 3.1 of CEB-SS-5.10 for 5% damping. The TRS shown on page 5-5 meets or exceeds all points of the TVA standard RRS. Therefore, the seismic qualification of the WBN2 display module is provided by pages 5-4 and 5-5 for which the TRS completely envelopes the TVA standard RRS shown in Fig 3.1 of CEB-SS-5.10. Additionally, as previously stated, Calculation WCG-ACQ-0766 was issued to generate the 5% RRS for the WBN2 panel (2-M-30) where the safety related RM-1000 monitors will be installed. The vertical 5% RRS plot in calculation WCG-ACQ-0766 broad band peak is 4.2 g which is lower than the 5% TRS shown in 04508905-1SP", page 5-5, Figure 5-2. 3. Attachment 23, Qualification Test Report for RM-1000 Processor Module and Current-To-Frequency Converter (04508905-QR)", page 4-25, Figure 4-5 X-Axis SSE Test Response Spectra (TRS) versus Required Response Spectra (RRS) shows the TRS to be below the RRS at various frequency (5% Damping). Please provide an explanation regarding why this is acceptable.

The WINCISE-st yle IIS used at Watts Bar Unit 2 is essentiall y the same as the in-core power distribution measurement systems used at most Combustion Engineering style of operating reactors that use a type of in-core neutron sensors commonly called "Fixed In-core Detectors (FID)." The Watts Bar Unit 2 IIS is functionally identical to the IIS used in the Westinghouse 1 AP1000Ž reactor design. The Watts Bar Unit 2 IIS includes the FIDs, Core Exit Thermocouples (CET), FID and CET signal cables, the FID signal processing hardware, and the FID signal processing software. This hardware and software is required to provide the measured signals to the associated BEACON System to periodically determine whether the reactor is operating within design core peaking factor limits. A detailed description of the Watts Bar Unit 2 IIS hardware is provided in the document titled, "Westinghouse Incore Information Surveillance &

Engineering (WINCISE) System Technical Manual," NO-WBT-002, Revision 0 supplied by Westinghouse to TVA in September of 2010.

There is no other interface to safety systems. The CET signals are electrically isolated from signals output from the non-1E FID signals and signal processing electronics.

(e) The qualification for the BEACON S y stem to perform the core power distribution measurement function using the Watts Bar Unit 2 WINCISE style IIS instrumentation is documented in the generic NRC Safety Evaluation Reports (SER) provided with WCAP-12472-P-A. This WCAP generically approves the BEACON System for use at PWR reactors including those using Movable In-core Detector Systems (MIDS) like Watts Bar Unit 1 and, through Addendum I-A and 2-A, those like Watts

Bar Unit 2 using a WINCISE type fixed in-core instrumentation system.

The specific differences between the Unit 1 and Unit 2 core power distribution measurement systems are too numerous to simply list. A detailed description of the Watts Bar Unit 2 IIS hardware is provided in section 2 of the WINCISE System Technical Manual NO-WBT-002 (Attachment 5).

(f) NUREG-800 section 7.0-A, Table 7.0-A-1. Review Topics for Various Systems, requires only a limited review for non-safety related system discussed in NUREG-800 section 7.7 Control. WINCISE is a non-

safety-related, indication onl y s y stem within the scope of NUREG-800 section 7.7. The limited review required is: "Control systems receive a limited review as necessary to confirm that control system failures cannot have an adverse effect on safety system functions and will not pose frequent challenges to the safety systems." The only WINCISE interface with a safety-related system is the CET in the IITA which is hardwired to the Common Q PAMS system. See item (g) below for a description of the qualification process that demonstrates that failures in the balance of the WINCISE s ystem do not impact the performance of the safety-related CET function.

Open Due 4/15/11 Open-NRC Review 362 7.6.1 7.6.7 EICB ( Kemper & Singh) OI #331 requested TVA to provide information regarding how the Loose Parts Monitoring System (LPMS) in-containment components (e.g., 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 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. Also, provide justification for why vibration qualification if the Remote Charge Preamplifier is not required.

TVA committed to provide a letter on the docket (targeted is for 4/30/2011) stating why the the in-containment equipment has been qualified for vibration per RG 1.133, Rev. 1.

5. Open-TVA NRC Update (WEK)--On March 27, 2011 TVA provided a

document WBT-D-2782 in response to this OI. This document provides the in-containment LPMS equipment qualification specification(s) and indicates that "-the normal environmental conditions for a Westinghouse containment are reported in Tables 6-1 and 6-2 from WCAP 8587 Rev. 6, "Methodology for Qualifying Westinghouse WRD Supplied NSSS Safety Related Electrical Equipment".

Open-TVA/Bechtel 363 7.5.1.1.3 and 7.9.1 7.5.2 EICB (Rahn and Mossman) OI#199 requested TVA to provide information concerning how TVA plans to meet regulatory criteria for Quality (10 CFR 50.55a(a)(1)) associated with the Technical Support Center and Nuclear Data Link. TVA responded in Letter Dated October 5, 2010, Item 63; however, TVA's response does not address the quality aspects of these system features. A similar question had been asked for Quality Criteria adherence for the SPDS and the BISI functions of TVA Procedure SPP-2.6 "Computer Software Control" has been superseded by TVA Procedure NPG-SPP-12.7, "Computer Software Control," Revision 0, dated December 17, 2010 (Attachment 3).

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?

Specifically, what is the scope of TVA Procedure SPP-2.6 "Computer Software Control"? How does it apply to the ICS

functions of a) SPDS, b) BISI, and c) TSC and NDL functions? Wouldn't there be aspects of the quality procedures that apply to the development, maintenance, and operations of the software needed to support the data communications features. Also, what quality measures will be applied to develop, maintain, and operate the hardware that accomplishes the TSC and NDL functions to ensure that these features will be reliable and available when

needed? SPDS, b) BISI and c) Technical Support Center (TSC) and Nuclear Data Link (NDL) functionality is controlled by qualified personnel in accor dance with TVA procedure NPG-SPP-12.7. The TSC and NDL functions are provided and performed by the ICS and, in the case of NDL, the Central Emergency Control Center (CECC) computers in Chattanooga.

Any changes to ICS software must be documented and controlled using TVA procedure NPG-SPP-12.7. This includes the a) SPDS, b) BISI and c) TSC and NDL functions. The procedure details controls and processes required for the development, modification, and configuration management of computer software used to support the design, operation, modification, and maintenance of TVA's nuclear power plants consistent with the Nuclear Quality Assurance Plan.

Controls in NPG-SPP-12.7 guide the development and testing of the software changes. Other controls established by this procedure to further maintain quality standards are: The application custodian implements controls to prevent unauthorized changes to the software. Changes are made in a non-production environment, and validation testing takes place before the change is installed on the ICS when possible. Once validation testing begins, the source code is placed under configuration control. When the modifications are installed on the ICS, an operability test is performed to demonstrate that the software is installed correctly and is functioning correctly in its operating environment. Documentation related to ICS software changes are QA records. The software source code is kept in a physically secure, environmentally controlled space to prevent inadvertent changes. Cyber security considerations are also considered in the storage environment. The data goes through several validation steps before being presented to the operators. When redundant sensors are used, the data received by the computer can be processed by software to determine if the quality of one or more points is questionable.

The hardware involved in the TSC and NDL functionality is verified to be operable on a periodic basis.

In the case of the NDL functionality, the ICS transmits the required data to the CECC on a continuous basis. The CECC monitors the status of the ICS data communications and alarms are generated when the link is not active. The Emergency Plan (EP) staff conducts a quarterly test that verifies that NDL data is successfully transmitted from each unit to the NRC.

By letter dated 2/25/11 (ML110620219

), TVA docketed a response: TVA performed an analysis and concluded that the Common Q PAMS equipment does not need to meet either IEEE 279-1971 or

IEEE 603-1991 and so no analysis was performed or provided.

However, SRP (NUREG-0800 Rev. 2 dated March 2007) Section 7.7, "Information System Important to Safety," specifically identifies IEEE Std 603-1991 as being applicable to accident monitoring instrumentation. Based upon the review of this item, the staff finds the following open items:

1 TVA to demonstrate that the Common Q PAMS meets the applicable regulatory requirements in IEEE Std 603-1991. 2 TVA to updated FSAR (Amendment 103) Table 7.1-1 to reference IEEE Std 603-1991 for WBN2 Common Q PAMS and Sorento Containment High Radiation Monitors.

Std 603-1991. (Awaiting response from Westinghouse)

2. Table 7.1-1 will be updated to reference IEEE Std 603-1991 for the Common Q PAMS.

TVA has reviewed the requirements of IEEE Std 603-1991 for the Sorrento Containment High Range Radiation Monitors and determined that IEEE Std 603-1991 is not applicable. IEEE 603-1991 is applicable to actuation systems. While TVA lists the containment high range radiation monitors as RG 1.97 Revision 2 Typa A variables, the classification is not based on the RG 1.97 requirements which states:

"Type A, those variables that provide primary information needed to permit the control room operating personnel to take the specified manually controlled actions for which no automatic control is provided and that are required for safety systems to accomplish their safety functions for design basis accident event." TVA calculation WBN0SG4047, "

PAM Type "A" Variables Determination" uses a broader definition. The calculation definition is:

"The type "A" variables will be divided into three groups based on the parameter's purpose. The groups are: (1) event identification, (2) event recovery to plant stabilization, and (3) maintaining the stabilized conditions from event recovery to hot standby. Following a reactor trip, the termination point for transients at WBNP is considered a stabilized condition at hot standby per chapter 15 of the WBN FSAR. Event recovery actions are those manual actions taken to mitigate a design basis accident to a stabilized condition. The plant can be considered stabilized when the plant parameters var y slowl y and automatic s y stems are not being initiated. The diagnostic process consciously performed by the operator via the plant variables to interpret an event indication will be considered as a safety-related operator action regardless of the lack of manual manipulation of equipment. This diagnostic process is necessary to enable the operator to distinguish the "type" of transient and take the correct mitigating actions."

A review of TVA calculation WBN0SG4047 and the associated Emergency Instructions found that there are no operator actions that are meet the RG 1.97 Revision 2 definition for a Type A variable which are based on the containment high range radiation monitors. Based on this review, IEEE 603 is not applicable to the containment high range radiation monitors.

By letter dated 2/25/11 (ML110620219), TVA docketed a response.

The WBN2 FSAR (Amendment 103) references RG 1.153 Rev. 0, "Criteria for Safety Systems." The Common Q PAMS is designed to meet the requirements of RG 1.153 Rev. 1. By letter dated February 25, 2010 (ML110620219), TVA stated: "The subject Regulatory Guides [RG 1.153 Rev. 0 & 1] endorse and reference other standards. Common Q PAMS has been evaluated to comply with the requirements of these other endorsed standards ([Comparison report in this letter titled IEEE-279-1971 to IEEE-603-1991 Comparison]). Therefore no additional anal ysis needs to be performed and no further action is necessary." However, the "Comparison report in this letter titled IEEE-279-1971 to IEEE-603-1991 Comparison," stated:

"The first of the two standards, IEEE-279, is part of the design basis of WBN2 but is not relevant to Common Q PAMS. The second standard, IEEE-603-1991 is not part of the design basis for the Common Q PAMS forWBN2." Based on the reasoning quoted above, WBN2 did not evaluate the Common Q PAMS against the criteria of RG 1.153 Rev. 1; therefore, the staff finds the following open item (see also Open

10. Please clarify the following statement provided in Attachment 4, Page 25: "During certain accident scenarios, it is possible for the CETs to see temperatures up to 20 deg F different from Unit 1."

11. Attachment 4 and 5 explained that the Mineral Insulation cable allows the isolation of the core exit thermocouples (1E) and self-powered neutron detector (non-1E) signals. Please provide the analysis that evaluated this separation, as well as the evaluation that show that failure of the non-1E si g nal won't affect the 1E signal.

12. Page 129 of Attachment 4 states that a minimum of three thermocouples are operable in each quadrant. Table 7.5-2 of the SSER (R.G. 1.97) states that 4 thermocouples should be Agenda for Weekly Telecom with TVA (I&C Chapter 7 only) radD9A82.docx Open Items to be Resolved for SER Approval No. SE Sec. FSAR Sec. NRC POC Issue TVA Response(s) Response Acceptable Y/N Status/ Current Actions Resolution Path RAI No. & Date RAI Resp. Date Comments operable in each quadrant. Please explain if TVA is deviating from the requirements in R.G 1.97, and how this is justified.

13. Please provide information regarding the effects of a software common cause failure (SWCCF) on the IIS.

14. The FMEA provided by TVA on 4/15 has not been updated (see email from Steve Clark on 4/11). Also, the FMEA provided focus on failures during installation and commissioning and it does not identify measures for failures during operation. Last, this FMEA does not address software failures, only component failures and installation failures.

Please provide an updated and complete version of the FMEA

15. A ttachment 4, TVA document "Incore Instrumentation S ystem" describes the system requirements. Therefore, provide a complete system description of the IIS for the staff to evaluate the IIS to be installed in Watts Bar Unit 2.

Also, the description for the incore thermocouple system in this TVA document is inconsistent with the description provided in Westinghouse WINCISE Hardware Description (Attachment 5). For example, Section 1.2 of the TVA document states that there are 65 incore thermocouples and Section 2.2.9 describes that the incore thermocouples provide an input signal to the Inadequate Core Cooling Monitor.

16. TVA attachment 4 of the 4/15 letter show modifications to the DBE design criteria. Please provide detailed explanation about these modifications.

17. Please explain if new penetration and routing were required for IIS' signals. If new penetrations are required, explain how these were qualified. Also, explain the criteria used to route the power/control cables.

18. Questions on Technical Specification: (1) The TVA package states that TS 3.1 and TS Bases 3.1 were modified due to WINCISE. Please provide detailed information to evaluate the modifications to the TS. (2) The TVA mark up does not define the operating limits in the TS for the reactor power distribution. Please provide detailed information on how the IIS may impact the Technical Specification.

19. Redundancies are designed and built into the signal processing system to avoid impacting operation in the event of the loss of some SPD signals. The master signal processing rack data interface card provides the output data stream to the Application server. Each cabinet master si gnal processor rack contains redundant data interface cards. Loss of one data interface card will not result in a loss of data output from the cabinet. Provide detailed description on how this works (e.g., is the switchover software based?)

20. The Application Servers receive information from Signal Processing System (SPS Cabi nets), Integrated Computer System (ICS), and BEACON. The WINCISE IP Switches provide the main hub for traffic flow from the SPS cabinets, BEACON servers, Application Servers, and ICS. Provide Agenda for Weekly Telecom with TVA (I&C Chapter 7 only) radD9A82.docx Open Items to be Resolved for SER Approval No. SE Sec. FSAR Sec. NRC POC Issue TVA Response(s) Response Acceptable Y/N Status/ Current Actions Resolution Path RAI No. & Date RAI Resp. Date Comments detailed description of the communication among the Integrated Computer System (ICS) and the Beacon System and the Wincise's Application servers.

21. A ttachment 4, TVA document "Incore Instrumentation S ystem" describes that the WINCISE system includes a Domain server, which provides a supportive function and is not required for the PDMS to receive needed information from the Application Server. However, the domain server provides an environment for the development and maintenance of application and system software. Please explain how this domain server will be configured and used for WINCISE in WBN2. Note that the domain server is not part of the Westinghouse WINCISE Hardware Description (Attachment 5)

22. Page 52 of Attachment 4, question 1.5 was answered yes, but the I&C calculation to be provided in Sections 4 and 5 is not included. Please explain if this calculation was performed, and if so provide a description.

23. Pa ge 52 of Attachment 4, Section 6 does not include the block diagram of the proposed modification to WBN2. Please provide a block diagram if the system, including power sources.

376 7.7.9 EICB (Alvarado)

DCI-CVIB Input:

Reference-EDCR # 52321, Revision A-EDCR Unit Difference Form --- Bechtel Document

Page 2 -Maintenance Difference-The proposed In-Core Instrument Thimble Assemblies (IITAs) which will replace Movable In-C ore Detectable Systems (MIDs) have the following features:

(1) IITAs are not fully extracted and they are held in a movable frame assembly.

(2) IITAs exert lower vibration amplitude and therefore, aging degradation due to wear does not occur.

(3) Loss of reactor coolant system pressure boundary due to breach of IITA outer sheath does not occur.

Question:

The staff believes that the licensee should provide an inspection program to confirm that the aforementioned attributes associated with IITAs are valid and this inspection program can be a part of a routine maintenance program.

Replacement of 58 CETs for the current 65 CETs -to be addressed by the fuels division.

13. Related to OI 360 377 7.7.9 EICB (Alvarado) 1. (a) Further explanation is required for the sentence in EDCR 52321 Rev A Page 2, "During certain accident scenarios, it is possible for the CETs to see temperatures up to 20 degree F different from Unit 1". 14.

(c) Compare the accuracy for flux mapping with movable detectors (MIDS) and fixed detectors such as SPDs.

2. Explain how the linear heat generation rate is monitored using the new IITA system.

3. (a) Page 26 of the EDCR 52321-A states that "certain SPS electronics cannot withstand the increased pressure during an Integrated Leak Rate Testing (ILRT). As a result, these SPS electronics need to be removed prior to starting the ILRT." If SPS electronics does not survive an ILRT, what will be their status during a design basis accident, such as, loss of coolant accident?

(b) Page 129 of EDCR 52321-A Item Number 7 CET

Requirements states that "The CET must be operable before, during, and after a design basis accident without loss of safety function, and for the time required to perform the safety function."

Does this CET requirement conflict with the scenario in Part (a) above, such that the malfunction of the electronics during high pressure during the design basis accident?

4. BEACON Power Distribution Monitoring System (PDMS)

with WINCSE seems to be functioning different from old conventional BEACON monitoring system. Explain the differences between the new and old system and the advantages, if any, of the new system over the old one.

5. EDCR 52321-A Page 129 (WBN2-94-4003 Rev 0000 Page 18 of 41) "WINCISE Requirements" Sections 1 and 2 specify minimum requirements for inputs from SPDs such that "the

WINCISE s ystem shall not require input from 75%

(50% for Section

2) of the instrumented locations, with at least five operable SPD associated with the top half of the active core and at least five operable SPD associated with bottom half of the active core per quadrant,-." Section 3 states that "The WINCISE System will be

capable of performing its required core monitoring functions at or above 20% RTP." Provide documents supported by analyses that will show that the incore monitoring systems and the CET system will be fully capable of performing the intended functions under the circumstances prescribed in Sections 1, 2 and 3 of "WINCISE Requirements."

6. Section 6.0 of WCAP-12472-P-A Addendum 2-A stipulates that in addition to maintaining power distribution Technical Specification that require surveillance of parameters related to hot rod power and local power density, it will be necessary for the licensees to include a BEACON Operability specification in the

Technical Requirements Manual (TRM) associated with either the NUREG-1430 or NUREG-1432 format TS. Are the minimum requirements (50% and 75% of the instrument locations input) and functions of WINCISE and CET systems specified in Sections 1 through 6 of "WINSCISE Requirements" included in the WBN-2 Technical Specifications? If the answer is "no", explain wh
