25402-011-VIA-HARA-00219-001 General Atomics HARA RM-1000 EMC Test Report Supplement 1 (Redacted) 3.2 EMI/RFI Qualification Procedures The purpose of this section is to present acceptable EMI/RFI qualification methods and requirements to demonstrate that electrical and I & C (Instrument and Control) equipment can perform their important-to-safety functions for all data inputs and respond with all appropriate signals, warnings, data outputs and related information. As outlined in GA-ESI Doc. No. E-1 15-0699, this EMI/RFI qualification is only a part of the equipment qualification. In support of the Federal laws and to provide guidance to the nuclear industry, a number of standards and regulatory guides have been issued relative to EMI/RFI analysis and testing. These are as follows: 1) NRC RG 1.180, Guidelines for Evaluating Electromagnetic and Radio-Frequency Interference in Safety-Related Instrumentation and Control Systems, 2.) MIL-STD-461E, Requirements for the control of electromagnetic interference characteristics of subsystems and equipment, 3.) IEC 60880-2, Electromagnetic compatibility (EMC), Part 2, Environment -

Compatibility levels in industrial plants for low-frequency conducted disturbances, 4.) IEC 60880-4, Electromagnetic compatibility (EMC), Part 4, Testing and measurement techniques, 5.) IEC 60880-6, Electromagnetic compatibility (EMC), Part 6, Immunity for industrial environments, and 6.) NRC NUREG/CR-6782, Comparison of U.S. Military and International Electromagnetic Compatibility Guidance.

3.3 Additional EMI/RFI Qualification Requirements The NRC RG 1.180 Rev. 1, 2003 is a very complete document and no equivalent IEEE standard exists. RG 1.180 endorses both Military Standard MIL-STD-461E and the International Electrotechnical Commission (IEC) 61000 series of EMI/RFI test methods. It extends the guidance to cover signal line testing, incorporating frequency ranges where portable communications devices are experiencing increasing use, and relaxing the operating envelopes (test levels) when experience and confirmatory research warrants it. The following sections of Regulation Guide 1.180 show the relationship between MIL-STD-461E and IEC 61000.

Section 3 of Regulation Guide 1.180 for emissions testing states "The specific test methods acceptable to the NRC staff in regard to emissions testing for safety-related I&C systems in nuclear power plants are presented in Tables 2 and 3. Table 2 (8-1) lists the EMI/RFI emissions test methods in MIL-STD-461E while Table 3 (8-2) lists the corresponding criteria in IEC 61000-6-4, "Electromagnetic Compatibility (EMC) - Part 6: Generic Standards - Section 4: Emission standard for industrial environments." These test methods cover conducted (along power leads) and radiated interference emitted from equipment under test."

The GA-ESI Doc. No. E-1 15-0699 further expands on these requirements. They are followed at GA when the customer has not specified requirements or when GA uses these as generic requirements.

4. GA-ESI's QUALIFICATION PROGRAMS 4.1 GA-ESI's GENERIC QUALIFICATION PROGRAM GA-ESI's qualification program for radiation monitors was initiated in the mid-1970s. The first qualification programs related to environmental and seismic qualification of analog radiation monitors. In the late 1970s, the digital RM-80 and RM-23 were developed and EMI/RFI qualification was added. Software for the RM-80 and RM-23 was prepared under the control of a 10 CFR 50 Appendix B quality program. Verification and Validation (V&V) of this software to RG 1.152-1996 requirements were performed in 1997 after the regulatory guide was first issued. Development of the RM-2000, RM-2300, and RM-1000 included qualification of the monitors to the latest standards at the time of their development. These include environmental, seismic, Electromagnetic Compatibility (EMC), and software V&V. All qualification is performed by test, similarity to components that have been tested, or by design for mild environment conditions. Components required to operate in a harsh environment are qualified by testing only.

The following subsections describe specific subsection of Environmental program area (EMC) in more detail and describe the methods used to qualify the TVA replacement radiation monitors to the requirements in Section 3.

4.2 GA-ESI's ENVIRONMENTAL QUALIFICATION PROGRAM GA-ESI's environmental qualification program is described in Section 4 of GA-ESI document 02818905-QSR. OP-7-3-240 Rev. F and OP-7-3-250 Rev. E are used for this qualification. The steps taken in this qualification are as follows:

1. An analysis is performed to identify the differences between the monitor being qualified by this report and the monitor qualified by GA-ESI document 02818905-QSR and its supplements. As appropriate the assemblies, modules, components, and parts (items) are listed in a table in the Qualification Basis of this report.

04038800-1SP Rev. A Page 33

25402-011-VIA-HARA-00219-001 General Atomics HARA RM-1000 EMC Test Report Supplement I (Redacted)

2. The items that differ from those in GA-ESI document 02818905-QSR and its supplements will be identified and qualified in the manner described in section 4.2 of GA-ESI document 02818905-QSR.

4.3 GA-ESI's ELECTROMAGNETIC COMPATIBILITY QUALIFICATION PROGRAM RM-1000 modules were developed in the late 1990's and the former EMC test program was expanded to include the latest standards as well as TVA specification SS E18.14.01 and the guidance given by EPRI TR-1102323, September 1994 issue. The testing program included:

" Conducted Emissions to MIL-STD-461E CE101 and CE102;

" Radiation Emissions to Cenelec EN 55011 (1991) (Group 1, Class A);

  • Conducted Susceptibility to MIL-STD-461E CS1Oland IEC 1000-4-6 (1996) (IEC 801-6);
  • Radiated Susceptibility to IEC 1000-4-3 (1995) (IEC 801-3);

" Surge Susceptibility to IEC 1000-4-5 (1995) (IEC 801-5);

  • Electrical Fast Transient Immunity to IEC 1000-4-4 (1995) (IEC 801-4); and

" Electro-static Discharge (ESD) to IEC 1000-4-2 (1995) (IEC 801-2).

The RM-1000 module was tested again in 2003 as follows:

" Conducted Emissions to MIL-STD-461E CE101 and CE102;

" Radiation Emissions to MIL-STD-461E RE101;

  • Radiation Emissions to Cenelec EN 55022 (1994) (Class A);

" Conducted Susceptibility to MIL-STD-461E CS101and EN 61000-4-6 (1995) (IEC 1000-4-6);

" Radiated Susceptibility to MIL-STD-461E RS101 and EN 61000-4-3 (1995) (IEC 1000 3);

  • Magnetic Field Susceptibility to EN 61000-4-8 (1995) (IEC 1000-4-8);

" Surge Susceptibility to EN 61000-4-5 (1995) (IEC 1000-4-5);

  • Electrical Fast Transient Immunity to EN 61000-4-4 (1995) (IEC 1000-4-4);

" Voltage Fluctuation Ride Through Ability to EN 61000-4-11 (1994) (IEC 1000-4-11); and 04038800-15P Rev. A Page 34

Electro-static Discharge (ESD) to EN 61000-4-2 (1995) (IEC 1000-4-2).

The qualification basis for EMC is performed for the RM-1000 digital monitors in the following sections, where the following steps are performed.

1. The TVA specification requirements are compared to the test results of the same type monitor.
2. Differences are evaluated and justification provided to demonstrate that the monitor will perform satisfactorily.
3. For each monitor the configuration of the monitor is compared to the test article.

Differences in configuration are evaluated and justification provided to demonstrate that the monitor will perform satisfactorily

5. EMC QUALIFICATION BASIS Section 5 of the GA-ESI 04038903-7SP report demonstrates that GA-ESI PIN 04034101-001 (High Range Area Monitor System) Electromagnetic Compatibility (EMC) is qualified for operation in an industrial environment similar to that found at TVA's Watt Bar Unit 2.

AFFIDAVIT OF PAUL G. BERNER I, Paul G. Berner, Radiation Monitoring Systems Program Director of General Atomics Electronic Systems, Inc., do hereby affirm and state:

(1) I have been delegated the function of reviewing the information sought to be withheld by General Atomics Electronic Systems, Inc. and I am authorized to execute this affidavit on behalf of General Atomics Electronic Systems, Inc.

(2) The affidavit is submitted under the provisions of 10CFR Part 2.390 in order to withhold the enclosed confidential commercial information (as set forth in paragraph 3 following) of General Atomics Electronic Systems, Inc. from public disclosure or publication.

(3) The information sought to be withheld is related to General Atomics Electronic Systems' Radiation Monitoring System (i.e., RM-1000) and is contained in the documents designated as:

04038800-1SP RM-1 000 EMC Test Report Supplement 1 04038903-QSR Qualification Summary Report for Watts Bar Nuclear Plant Unit 2 Replacement Radiation Monitors The proprietary material in these documents is delineated by "business sensitive" or "trade secret" designation on specific paragraphs and highlighted text, sentence, figure or drawing to which the designation applies.

(4) In making this application for withholding of proprietary information of which it is the owner, General Atomics Electronic Systems, Inc. relies upon the exemption from disclosure set forth is the Freedom of Information Act ("FOIA"), 5 USC Sec. 552.(b)(4) and the Trade Secrets Act, 18 USC Sec. 1905, and NRC regulations 10CFR Part 9.17(a)(4) and 2.390(a)(4) for "trade secrets and commercial or financial information obtained from a person and privileged or confidential." The material for which exemption from disclosure is hereby sought is all "confidential commercial information," and some portions also qualify under the narrower

25402-011 -VI A-HARA-00217-001 General Atomics HARA 4496 Letter for GA ESI & Affidavit Package Enclosure to GA/GA-ESI Letter No. GA-ESI 4496 Page 2 of 4 definition of "trade secret," within the meanings assigned to those terms for purposes of FOIA Exemption 4 in, respectively, Critical Mass Energy Project v.

Nuclear Regulatory Commission, 975F2d871 (DC Cir. 1992), and Public Citizen Health Research Group v. FDA, 704F2d1280 (DC Cir. 1983).

(5) Some examples of categories of information which fit into the definition of proprietary information are:

a. Information that discloses a process, method, or apparatus, including supporting data and analyses, where prevention of its use by General Atomics Electronic Systems, Inc.'s competitors without license from General Atomics Electronic Systems, Inc. constitutes a competitive economic advantage over other companies;
b. Information which, if used by a competitor, would reduce his or her expenditure of resources or improve his or her competitive position in the design, manufacture, shipment, installation, assurance or quality, or licensing of a similar product.
c. Information which discloses patentable subject matter for which it may be desirable to obtain patent protection.

(6) The information sought to be withheld is being submitted to the NRC in confidence. The information is of a sort customarily held in confidence, is of a sort customarily held in confidence by General Atomics Electronic Systems, Inc.,

and is in fact so held. The information sought to be withheld has, to the best of my knowledge and belief, consistently been held in confidence by General Atomics Electronic Systems, Inc. No public disclosure has been made, and it is not available in public sources. All disclosures to third parties, including any required transmittals to the NRC, have been made, or must be made, pursuant to regulatory provisions or proprietary agreements which provide for maintenance of the information in confidence. Its initial designation as proprietary information, and the subsequent steps taken to prevent its unauthorized disclosure, are as set forth in paragraphs (7) and (8) following.

(7) Initial approval of proprietary treatment of a document is made by the manager of the originating component, the person most likely to be acquainted with the value and sensitivity of the information in relation to industry knowledge. Access to such documents within General Atomics Electronic Systems, Inc. is controlled to protect it from unauthorized disclosure.

25402-011 -VIA-HARA-00217-001 General Atomics HARA 4496 Letter for GA ESI &Affidavit Package Enclosure to GA/GA-ESI Letter No. GA-ESI 4496 Page 3 of 4 (8) The procedure for approval of external release of such a document typically requires review by the staff manager, project manager, principal scientist or other equivalent authority, by the manager of the cognizant marketing function (or his designee), and by the Legal Department, for technical content, competitive effect, and determination of the accuracy of the proprietary designation. Disclosures outside General Atomics Electronic Systems, Inc. are limited to regulatory bodies, customers, and potential customers, and their agents, suppliers, and licensees, and others with a legitimate need for the information, and then only in accordance with appropriate regulatory provisions or proprietary agreements for protecting the information from further disclosure.

(9) The information classified as proprietary was developed and compiled by General Atomics Electronic Systems, Inc. at a significant cost to General Atomics Electronic Systems, Inc. This information is classified as proprietary because it contains detailed historical data and analytical results not available elsewhere.

This information would provide other parties, including competitors, with information from General Atomics Electronic Systems, Inc. technical database and the results of evaluations performed using codes developed by General Atomics Electronic Systems, Inc. Release of this information would improve a competitor's position without the competitor having to expend similar resources for the development of the database. A substantial effort has been expended by General Atomics Electronic Systems, Inc. to develop this information.

(10) Public disclosure of the information sought to be withheld is likely to cause substantial harm to General Atomics Electronic Systems, Inc.'s competitive position and foreclose or reduce the availability of profit-making opportunities.

The information is part of General Atomics Electronic Systems, Inc.'s comprehensive radiation monitoring system technology base, and its commercial value extends beyond the original development cost.

The value of the technology base goes beyond the extensive physical database and analytical methodology, and includes development of the expertise to determine and apply the appropriate evaluation process.

The research, development, engineering, and analytical costs comprise a substantial investment of time and money by General Atomics Electronic Systems, Inc.

General Atomics Electronic Systems, Inc. competitive advantage will be lost if its competitors are able to use the results of the General Atomics Electronic Systems, Inc.'s experience to normalize or verity their own process or if they are able to claim an equivalent understanding by demonstrating that they can arrive at the same or similar conclusions.
