Electromagnetic Compatibility (EMC)Electromagnetic Interference (EMI)Mild Environment Operating Basis Earthquake (OBE)Qualification Radio Frequency Interference (RFI)Required Response Spectra (RRS)The ability of equipment or system to function satisfactorily in its electromagnetic environment without introducing intolerable electromagnetic disturbances to anything in that environment.

Electromagnetic disturbance which manifests itself in performance degradation, malfunction or failure of electrical or electronic equipment.

An environment expected as a result of normal service conditions and, extremes (abnormal) in service conditions where seismic is the only Design Basis Event (DBE) of consequence.

An earthquake that could reasonably be expected to occur at the plant during the operating life of the plant considering the regional and local geology and seismology and specific characteristics of local subsurface material.

It is that earthquake that produces the vibratory ground motion for which those features of the nuclear power plant, necessary for continued operation without undue risk to the health and safety of the public, are designed to remain functional.

The generation and maintenance of evidence to ensure that the equipment will operate on demand to meet the system performance requirements.

Used interchangeably with EMI. EMI includes the entire electromagnetic spectrum; RFI is more restricted to the radio-frequency band, generally considered to be between 10 kHz and 10 GHz.The response spectrum issued by the user or agent as part of the equipment specification for seismic qualification purposes.

The RRS is a plot of the acceleration versus frequency describing the energy content of the earthquake time history. The RRS constitutes the requirement to be met during qualification activities.

An earthquake that is based upon an evaluation of the maximum earthquake potential considering the regional and local geology and seismology and specific characteristic of local subsurface material.

It is the earthquake that produces the maximum vibratory ground motion for which certain structures, systems, and components are designed to remain functional.

These structures, systems, and components are those necessary to ensure the integrity of the reactor coolant pressure boundary; the capability to shut down the reactor and maintain it in a safe shutdown condition; and the capability to prevent or mitigate the consequences of accidents that could result in potential off-site exposures comparable to the 10 CFR Part 100 guidelines.

Equipment that is relied upon to remain functional during and following a DBE to ensure the integrity of the reactor coolant pressure boundary;the capability to shut down the reactor and maintain it in a safe condition; and the capability to prevent or mitigate consequences of accidents that could result in potential off-site exposures comparable to the 10 CFR Part 100 guidelines.

A classification of structures, systems and components that shall be designed to withstand the effects of an SSE and maintain the specified design function and integrity.

The response spectrum that is developed from the actual time history of the motion of the shake table.The acceleration level of the high frequency, non-amplified portion of the response spectrum.

This acceleration corresponds to the maximum peak acceleration of the time history used to derive the spectrum.EQ-QR-68-WBT-NP, Rev. 0 xiv Westinghouse Non-Proprietary Class 3 Nuclear Automation Watts Bar Unit 2 NSSS Qualification Summary Report for Completion Program I&C Projects Post-Accident Monitoring System (PAMS)REFERENCES Following is a list of references used throughout this document.1.

PAMS is a Class 1E safety-related alarm and display system. The WBT PAMS consists of two independent trains of equipment (Trains A and B) which acquire and process two trains of inputs. The trains are physically separated and electrically isolated from each other. Each train of the WBT PAMS comprises two Advant Controller 160 (AC 160) racks, a primary rack and an extension rack, located in one standard 7721 seismic safety cabinet. For each train, the Primary AC 160 rack contains a processor module that processes the Common Q PAMS algorithms and a communication interface module for communicating data on the AF100 bus. The processor performs input processing and algorithms, and sends the outputs to its output cards and over the AF 100 to the operator's module (OM). The OM is used to provide various display pages to the operator.

The OM uses the Flat Panel Display System (FPDS), which consists of a PC node box, an FPD with touch screen capability, and a standard AF 100 communication interface for communication to the processor module.Per WBT-D-0088, "Transmittal of Westinghouse Comments on TVA Specification EDCR52351

," (Reference 1), the WBT PAMS cabinets are located in the Auxiliary Instrument Room (AIR) and the OM is located in the main control room (MCR); both the AIR and MCR are mild environment locations.

The basic objectives for qualification of safety-related electrical equipment are: " To reduce the potential for common mode failures due to environmental effects." To demonstrate that safety-related electrical equipment is capable of performing its designated safety-related functions during and after a design basis event (DBE).The objectives were met by monitoring the performance during testing and subsequent evaluations to demonstrate the AC160 safety system platform hardware supplied for the WBT PAMS is qualified to WBT plant-specific seismic, environmental, and EMC requirements.

The AC 160 safety system platform hardware used in the WBT PAMS application has been previously qualified.

Evaluations were performed to demonstrate that the existing seismic, environmental, and EMC qualification records satisfy the plant-specific requirements for WBT. The evaluations are summarized within this report.(Last Page of Section 1)EQ-QR-68-WBT-NP, Rev. 0 1-1 Westinghouse Non-Proprietary Class 3 Nuclear Automation Watts Bar Unit 2 NSSS Completion Program I&C Projects Qualification Summary Report for Post-Accident Monitoring System (PAMS)SECTION 2 EQUIPMENT IDENTIFICATION AND QUALIFICATION

SUMMARY

2.1 EQUIPMENT IDENTIFICATION The WBT PAMS equipment is installed in two cabinets and on the main control board (MCB), as a part of the OM. The standard 7721 seismic safety cabinet is used as the system cabinet, which is typically used for installing AC160 safety system platform equipment.

Each type test (EMC, environmental, and seismic) was performed to demonstrate that the EUT were capable of performing the specified safety function(s) within the specified performance criteria.Per the Safety Evaluation Report (SER) contained in WCAP-16097-P-A, "Common Qualified Platform Topical Report" (Reference 5), the U.S. Nuclear Regulatory Commission (NRC) requires a plant-specific evaluation of the generic qualifications to be performed for the plant-specific application of the Common Q equipment; this requirement is captured as Plant Specific Action Item 6.4. The plant-specific evaluation is to demonstrate that the WBT PAMS AC160/Common Q hardware is qualified based on component or equipment similarity to the previously qualified AC 160/Common Q hardware and that the AC 160/Common Q hardware is qualified for the WBT plant-specific requirements.

SUMMARY

OF QUALIFIED EQUIPMENT In summary, the WBT PAMS cabinet equipment, as identified in Drawing 10047E63 (Reference 2), is EMC, environmentally, and seismically qualified to the WBT EMC, environmental, and seismic qualification requirements specified in WNA-DS-01617-WBT-P, "Watts Bar 2 NSSS Completion Program I&C Projects Post Accident Monitoring System -System Requirements Specification" (Reference 6). The WBT PAMS OM equipment, as identified in Drawing 10004D82 (Reference 3), is EMC and environmentally qualified to the WBT EMC and environmental qualification requirements specified in WNA-DS-01617-WBT-P (Reference 6). The OM equipment qualified seismic levels are contained within this report along with the qualified mounting configurations of each OM component.

Westinghouse was not responsible for the installation of the OM equipment.

Therefore, determining if the OM equipment is seismically qualified to the WBT seismic qualification requirements for the OM equipment locations is not in the scope of this report.(Last Page of Section 2)EQ-QR-68-WBT-NP, Rev. 0 2-8 Westinghouse Non-Proprietary Class 3 Nuclear Automation Watts Bar Unit 2 NSSS Completion Program I&C Projects Qualification Summary Report for Post-Accident Monitoring System (PAMS)SECTION 3 EQUIPMENT PERFORMANCE SPECIFICATION 3.1 SAFETY FUNCTION I]a,c 3.2 PERFORMANCE REQUIREMENTS The PAMS cabinets, the equipment mounted within, and the OM components must demonstrate:

4.2 ENVIRONMENTAL The WBT PAMS environmental qualification requirements are specified in WNA-DS-01617-WBT-P (Reference 6), which identifies that the WBT PAMS cabinet equipment and OM equipment shall be qualified to the environmental qualification requirements described in Appendix 1 of WCAP- 16097-P-A (Reference 5). Per Appendix 1 of WCAP- 16097-P-A (Reference 5), the environmental qualification shall be performed in accordance with IEEE Standard 323-1983, "IEEE Standard for Qualifying Class 1E Equipment for Nuclear Power Generating Stations" (Reference 10). WCAP-16097-P-A (Reference 5)also identifies the expected room abnormal temperature and humidity parameters, where the Common Q cabinets will be installed; these are shown in Table 4.2-1. The environmental qualification test conditions for Common Q equipment installed in a cabinet are shown in Table 4.2-2.Per WNA-DS-01617-WBT-P (Reference 6), the WBT PAMS cabinets and the equipment therein, and the WBT PAMS OM equipment shall be qualified for the WBT plant-specific environment conditions defined in Table 4.2-3 and Table 4.2-4, respectively.

Table 4.2-3 and Table 4.2-4 provide the abnormal environmental conditions for the AIR and MCR at WBT.For the equipment installed inside an enclosure, the heat rise inside that enclosure needs to be considered in the environmental conditions.

Therefore, the WBT PAMS equipment that is housed inside the PAMS cabinet will be exposed to the environmental conditions defined in Table 4.2-3. However, the temperature conditions would be increased by the heat rise inside the WBT PAMS cabinet. Per WNA-TR-02383-WBT, "Post Accident Monitoring System Cabinet Hardware Test Report" (Reference 11), the WBT PAMS cabinet heat rise temperature observed during the cabinet hardware test was [ ]a,,. For the environmental qualification of the WBT PAMS cabinet equipment, a cabinet heat rise of [ a,c was conservatively assumed.The generic abnormal environmental qualification test parameters in Table 4.2-2 envelop the WBT environmental conditions shown in Table 4.2-3 (including the conditions inside the cabinet) and Table 4.2-4. Thus demonstrating that the WBT PAMS equipment is qualified to the required conditions specified in Table 4.2-2; it also demonstrates the qualification for the plant-specific environmental conditions (Table 4.2-3 and Table 4.2-4) at WBT.EQ-QR-68-WBT-NP, Rev. 0 4-4 Westinghouse Non-Proprietary Class 3 EQ-QR-68-WBT-NP, Rev. 0 4-4 Westinghouse Non-Proprietary Class 3 Nuclear Automation Watts Bar Unit 2 NSSS Completion Program I&C Projects Qualification Summary Report for Post-Accident Monitoring System (PAMS)Table 4.2-1.

The AC I 60/Common Q hardware was originally qualified for seismic, environmental, and EMC, as part of the base Common Q qualification program, which is documented in 00000-ICE-37764,"Summary Qualification Report of Hardware Testing for Common Q Applications" (Reference 23).Qualification tests have been performed on components that have been changed since completion of this base program due to product evolution, improvement, and/or obsolescence.

The qualification of the WBT PAMS AC 160/Common Q equipment is based on the test programs identified in Table 5.1-1. The test programs that are identified were not performed specific for the WBT application of the AC 160/Common Q hardware.

Section 6 provides a plant-specific evaluation to demonstrate that the WBT PAMS AC 160/Common Q hardware is qualified based on similarity to the qualified AC 160/Common Q hardware and that the AC 160/Common Q hardware is qualified for the WBT plant-specific requirements; this plant-specific evaluation addresses Plant Specific Action Item 6.4 as required by the NRC's SER contained in WCAP-16097-P-A (Reference 5).Table 5.1-1.

The components used in PAMS are either identical or similar to the qualified component.

If the component is similar to a tested component, similarity justification for qualification is provided by the evaluations contained in CN-EQT-10-55 (Reference 39).As shown in Table 5.2-1, the AC160/Common Q hardware was type tested in the various test programs and satisfied the requirements of EPRI TR-102323 (Reference

8) and RG 1.180 (Reference 7), as applicable.

Based on the EMC type testing and similarity evaluations performed, it is concluded that the qualified AC 160/Common Q hardware EMC conditions envelops the WBT PAMS EMC requirements stated in Section 4.1, when installed as detailed in Section 7.The plant-specific evaluation of the WBT PAMS equipment EMC qualification is documented in CN-EQT-10-55 (Reference 39).6.3 ENVIRONMENTAL Table 6.1-1 and Table 6.1-2 identify the environmental qualification basis for components used in the PAMS cabinet and OM, respectively.

The components used in PAMS are either identical or similar to the qualified component.

If the component is similar to a tested component, similarity justification for qualification is provided by the evaluations contained in CN-EQT-10-49 (Reference 38).The AC160/Common Q hardware was exposed to the environmental conditions shown in Table 5.3-1.The voltage and frequency of the power supplies were also varied during these test programs, as shown in Table 5.3-1. The AC 160/Common Q hardware qualified environmental conditions envelop the WBT PAMS environmental requirements as defined in Section 4.2 (Table 4.2-2).Based on the qualification testing and similarity evaluations performed, it is concluded that the AC 160/Common Q hardware is qualified for the WBT PAMS application.

The plant-specific evaluation of the WBT PAMS equipment environmental qualification is documented in CN-EQT-10-49 (Reference 38).EQ-QR-68-WBT-NP, Rev. 0 6-12 Westinghouse Non-Proprietary Class 3 Nuclear Automation Watts Bar Unit 2 NSSS Completion Program I&C Projects Qualification Summary Report for Post-Accident Monitorin2 System (PAMS)6.4 SEISMIC 6.4.1 WBT PAMS Cabinet Dynamic Similarity Analysis]a,c The dynamic similarity analysis is documented in CN-EQT-10-44 (Reference 42).]a"c The summary results of this dynamic similarity analysis are listed in Table 6.4-1.Table 6.4-1.

As stated in subsection 6.4.1, the WBT PAMS cabinet was shown to be dynamically similar to the AC 160 cabinet tested in EL:6681 (Reference 36).Table 6.1-1 identifies various seismic test programs that provide the seismic qualification basis for the equipment housed within the PAMS cabinet; these programs are documented in 00000-ICE-37764 (Reference 23), EQLR-171 (Reference 25), LTR-EMPE-03-26 (Reference 27), EQLR-169A (Reference 30), EQLR-159 (Reference 31), EQLR-168 (Reference 32), EQLR-178 (Reference 33), 00000-ICE-37773 (Reference 34), EQLR-182 (Reference 35), EL:6681 (Reference 36), EQ-EV-62-WBT (Reference 49), EQLR- 130 (Reference 50), and EQLR- 124 (Reference 51).To demonstrate that the resulting qualified levels from these various seismic test programs apply to WBT, the qualifying OBE and SSE levels must envelope the WBT OBE and SSE amplified RRS for the WBT PAMS cabinet.6.4.2.1 Development of WBT OBE and SSE Amplified RRS[]ac The WBT OBE and SSE amplified RRS have been compared to the qualified levels from the various seismic test programs identified in Table 6.1-1; these comparisons are provided in Subsections 6.4.2.2 through 6.4.2.14.

SUMMARY

AND CONCLUSIONS The qualification testing performed on the AC 160/Common Q hardware demonstrates that the WBT PAMS equipment is EMC, environmentally and seismically qualified for the WBT Class 1E application per the guidance contained in IEEE Standards 323-1983 and 344-1975 (References 10 and 13, respectively).

The equipment has also demonstrated EMI/EMC compatibility for safety application in nuclear power plants according to the guidance provided in U.S. NRC Regulatory Guide 1.180, Rev. 1 (Reference

7) for emissions and susceptibility.

The equipment has also demonstrated the ESD susceptibility requirements of EPRI TR- 102323 (Reference 8).Note that Westinghouse was not responsible for the installation of the OM equipment.

Therefore, determining if the OM equipment is seismically qualified to the WBT seismic qualification requirements for the OM equipment locations is not in the scope of this report. However, this report does contain the seismic levels that the OM equipment is qualified to and the mounting configurations that the qualification is based upon.(Last Page of Section 8)EQ-QR-68-WBT-NP, Rev. 0 8-1 Westinghouse Non-Proprietary Class 3 Attachment 6 TVA Letter Dated March 16, 2011 Responses to Licensee Open Items to be Resolved for SER Approval Westinghouse Electric Company CWA-11-3118, Application for Withholding Proprietary Information from Public Disclosure, EQ-QR-68-WBT-P, Revision 0 "Qualification Summary Report for Post-Accident Monitoring System (PAMS)," (Proprietary), Dated February 28, 2011 1

The proprietary information for which withholding is being requested in the above-referenced report is further identified in Affidavit CAW- 11-3118 signed by the owner of the proprietary information, Westinghouse Electric Company LLC. The affidavit, which accompanies this letter, sets forth the basis on which the information may be withheld from public disclosure by the Commission and addresses with specificity the considerations listed in paragraph (b)(4) of 10 CFR Section 2.390 of the Commission's regulations.

Accordingly, this letter authorizes the utilization of the accompanying affidavit by Tennessee Valley Authority.

Correspondence with respect to the proprietary aspects of the application for withholding or the Westinghouse affidavit should reference this letter, CAW- 11-3118, and should be addressed to J. A. Gresham, Manager, Regulatory Compliance, Westinghouse Electric Company LLC, Suite 428, 1000 Westinghouse Drive, Cranberry Township, Pennsylvania 16066.Very truly yours, (J. A. Gresham, Manager Regulatory Compliance Enclosures CAW- 11-3118 AFFIDAVIT COMMONWEALTH OF PENNSYLVANIA:

ss COUNTY OF BUTLER: Before me, the undersigned authority, personally appeared J. A. Gresham, who, being by me duly sworn according to law, deposes and says that he is authorized to execute this Affidavit on behalf of Westinghouse Electric Company LLC (Westinghouse), and that the averments of fact set forth in this Affidavit are true and correct to the best of his knowledge, information, and belief: J. A. Gresham, Manager Regulatory Compliance Sworn to and subscribed before me this 28th day of February 2011 Notary Pbi COMMONWEALTH OF PENNSYLVANIA Notarial Seal Cynthia Olesky, Notary Public Manor Boro, Westmoreland County My Commission Expires July 16, 2014 Member. Pennsvlvania Assodation of Notaries 2 CAW-1 1-3118 (1) 1 am Manager, Regulatory Compliance, in Nuclear Services, Westinghouse Electric Company LLC (Westinghouse), and as such, I have been specifically delegated the function of reviewing the proprietary information sought to be withheld from public disclosure in connection with nuclear power plant licensing and rule making proceedings, and am authorized to apply for its withholding on behalf of Westinghouse.

(2) 1 am making this Affidavit in conformance with the provisions of 10 CFR Section 2.390 of the Commission's regulations and in conjunction with the Westinghouse Application for Withholding Proprietary Information from Public Disclosure accompanying this Affidavit.

(3) I have personal knowledge of the criteria and procedures utilized by Westinghouse in designating information as a trade secret, privileged or as confidential commercial or financial information.

(4) Pursuant to the provisions of paragraph (b)(4) of Section 2.390 of the Commission's regulations, the following is furnished for consideration by the Commission in determining whether the information sought to be withheld from public disclosure should be withheld.(i) The information sought to be withheld from public disclosure is owned and has been held in confidence by Westinghouse.(ii) The information is of a type customarily held in confidence by Westinghouse and not customarily disclosed to the public. Westinghouse has a rational basis for determining the types of information customarily held in confidence by it and, in that connection, utilizes a system to determine when and whether to hold certain types of information in confidence.

The application of that system and the substance of that system constitutes Westinghouse policy and provides the rational basis required.Under that system, information is held in confidence if it falls in one or more of several types, the release of which might result in the loss of an existing or potential competitive advantage, as follows: (a) The information reveals the distinguishing aspects of a process (or component, structure, tool, method, etc.) where prevention of its use by any of 3 CAW- 11-3118 Westinghouse's competitors without license from Westinghouse constitutes a competitive economic advantage over other companies.(b) It consists of supporting data, including test data, relative to a process (or component, structure, tool, method, etc.), the application of which data secures a competitive economic advantage, e.g., by optimization or improved marketability.(c) Its use by a competitor would reduce his expenditure of resources or improve his competitive position in the design, manufacture, shipment, installation, assurance of quality, or licensing a similar product.(d) It reveals cost or price information, production capacities, budget levels, or commercial strategies of Westinghouse, its customers or suppliers.(e) It reveals aspects of past, present, or future Westinghouse or customer funded development plans and programs of potential commercial value to Westinghouse.(f) It contains patentable ideas, for which patent protection may be desirable.

There are sound policy reasons behind the Westinghouse system which include the following: (a) The use of such information by Westinghouse gives Westinghouse a competitive advantage over its competitors.

It is, therefore, withheld from disclosure to protect the Westinghouse competitive position.(b) It is information that is marketable in many ways. The extent to which such information is available to competitors diminishes the Westinghouse ability to sell products and services involving the use of the information.(c) Use by our competitor would put Westinghouse at a competitive disadvantage by reducing his expenditure of resources at our expense.

4 CAW- 11-3118 (d) Each component of proprietary information pertinent to a particular competitive advantage is potentially as valuable as the total competitive advantage.

If competitors acquire components of proprietary information, any one component may be the key to the entire puzzle, thereby depriving Westinghouse of a competitive advantage.(e) Unrestricted disclosure would jeopardize the position of prominence of Westinghouse in the world market, and thereby give a market advantage to the competition of those countries.(f) The Westinghouse capacity to invest corporate assets in research and development depends upon the success in obtaining and maintaining a competitive advantage.(iii) The information is being transmitted to the Commission in confidence and, under the provisions of 10 CFR Section 2.390; it is to be received in confidence by the'Commission.(iv) The information sought to be protected is not available in public sources or available information has not been previously employed in the same original manner or method to the best of our knowledge and belief.(v) The proprietary information sought to be withheld in this submittal is that which is appropriately marked in EQ-QR-68-WBT-P, Rev. 0, "Qualification Summary Report for Post-Accident Monitoring System (PAMS)" (Proprietary), dated February 2011, for submittal to the Commission, being transmitted by Tennessee Valley Authority letter and Application for Withholding Proprietary Information from Public Disclosure, to the Document Control Desk. The proprietary information as submitted by Westinghouse is that associated with the Watts Bar 2 Post Accident Monitoring System and may be used only for that purpose.

5 CAW- 11-3118 This information is part of that which will enable Westinghouse to: (a) Provide environmentally qualified Post Accident Monitoring Systems to its customers.(b) Maintain competitive position in the workplace.

Further this information has substantial commercial value as follows: (a) Westinghouse plans to sell the use of similar information to its customers for the purpose of maintaining Westinghouse-designed systems.(b) Westinghouse can sell support and defense of licensing.(c) The information requested to be withheld reveals the distinguishing aspects of a methodology which was developed by Westinghouse.

Public disclosure of this proprietary information is likely to cause substantial harm to the competitive position of Westinghouse because it would enhance the ability of competitors to provide similar analysis and licensing defense services for commercial power reactors without commensurate expenses.

Also, public disclosure of the information would enable others to use the information to meet NRC requirements for licensing documentation without purchasing the right to use the information.

The development of the technology described in part by the information is the result of applying the results of many years of experience in an intensive Westinghouse effort and the expenditure of a considerable sum of money.In order for competitors of Westinghouse to duplicate this information, similar technical programs would have to be performed and a significant manpower effort, having the requisite talent and experience, would have to be expended.Further the deponent sayeth not.
