Qualification Requirements
3.1 General
Reference 2.1 a provides the top level ENW requirements for the CGS PRNM system. Ref. 2.1 a directly includes the environmental requirements for the CGS PRNM equipment, and indirectly includes the EMC and seismic requirements for the PRNM instruments by invoking Ref. 2.lb. Ref. 2.1b further invokes Ref. 2.1c. Reference 2.1d is the licensing basis for the CGS PRNM, so it is treated as a CGS requirement. CGS-specific seismic spectra are not included in Ref. 2.1a, so the generic NUMAC requirements in Ref. 2.1c will be applied for the PRNM equipment. Seismic qualification of the PRNM P608 panel is documented in Refs. 2.2.2a, which also includes the CGS-specific seismic floor spectra. Qualification levels of the PRNM instruments are documented in this Qualification Summary. Seismic qualification of the P603 panel is not within the scope of this analysis, and must be confirmed by ENW. [[]]Reference
- 2. la, which invokes Ref. 2. lb, is developed from the ENW project inputs to define the specific CGS PRNM system and equipment requirements.
These requirements, in turn, provide the inputs to define the equipment for the project, documented in Ref. 2.1e, which includes the panel assembly, Ref. 2.1f.Together, these references are used for this qualification summary to define the equipment that must be addressed and the qualification requirements for that equipment. The CGS requirements apply to the equipment as installed at the site. However, to "partition" the design and qualification process and to support future spares qualification assessments, the GEH design documents (Ref. 2.1a and supporting documents) also define instrument level requirements for environmental and seismic qualification. To fully respond to the referenced requirements, this qualification summary must show that the environmental and seismic conditions are met both at the instrument level and at the "installed equipment" level. The EMC requirements apply only to the equipment as installed in the CGS panels.3.2 Environmental Requirements
3.2.1 Instruments
In accordance with the CGS PRNM requirements specification (Refs. 2.1a and 2.1b), the CGS PRNM instruments (i.e., NUMAC instruments) are required to function without degradation when subjected to the environmental conditions imposed by the NUMAC design requirements specification (Ref. 2.1c).Those requirements are shown in Table 3.1. The instrument environmental requirements are the same as the requirements used for the generic PRNM qualification (Refs. 2.2. la, b, c, f and i.).

- 2. la invoking Ref. 2. 1b), CGS PRNM instruments are to function without degradation when subjected to the seismic response spectra defined by the NUMAC design requirements specification (reference 2.1c). The seismic Required Response Spectra (RRS) for both horizontal and vertical motion (3% damping) is defined by the "break" points in Table 3.3. The instrument seismic requirements are the same as the requirements used for the generic PRNM qualification (Refs. 2.2.1a, b, d, f and i.). While Table 3.3 gives the minimum qualification levels, the actual qualification Test Response Spectrum (TRS) exceeded those levels over the frequency range.

_____]L 3.3.2 Panels In accordance with the PRNM requirements specification for CGS (see Ref. 2.1a), CGS PRNM instruments when installed in the PRNM panels are to function without degradation when the panels are subjected to the CGS seismic spectrum for SSE and OBE accelerations. That spectrum and a comparison to the instrument RRS (Table 3.3) as well as the actual instrument TRS are documented in Refs. 2.2.2a for panel P608. Qualification of Control Room Panel P603 will be confirmed and documented by ENW.The qualification level of the instruments mounted in Control Room P603 is documented in this Qualification Summary, Section 4. [[]]3.4 Electromagnetic Compatibility (EMC)References 2.1b, invoked by Ref. 2.1a, and 2.1d provide the generic PRNM EMC requirements. Those are used as the requirements applicable to qualification of the PRNM instruments. However, where additional qualification work beyond that required to meet those References has been completed, those results to the extent they apply to CGS are also included to more completely document the qualified level of the equipment. [[Since the PRNM equipment qualification was performed using earlier revisions of the EMC tests, and since no CGS specific site survey is available, adequacy of the PRNM EMC will be determined by comparing the actual qualification test levels/frequencies used to the more restrictive of those identified in Ref. 2.1d (LTR) and Ref. 2.3.3.1a (latest revision of USNRC Reg. Guide 1.180)Table 3.6 compares the test methods used for the PRNM qualification to those identified in Ref. 2.3.3. la.Tables 3.4 and 3.5 include the EMC qualification requirements based on Ref. 2. 1 d, which are equivalent to those in Ref. 2.1b, plus recommended test levels for comparable tests identified in Ref. 2.3.3.1a. The analyses comparing actual qualification performed against these requirements are included in Section 4 of this report.

Qualification Results 4.1 CGS Instrument Qualification 4.1.1 CGS PRNM Instrument Requirements The environmental, seismic, and EMC conditions applicable to the CGS PRNM instruments are defined in paragraphs 3.2.1, 3.3.1, and 3.4, respectively. The first two are to be met by the instruments alone (in addition to the panel level conditions covered in section 4.2). The EMC conditions are addressed only for instruments installed in the panel.4.1.2 Generic PRNM Instrument Qualification Levels Environmental and seismic qualification of [[]] Each instrument in a set of NUMAC PRNM instruments (collectively termed the "generic" PRNM instruments) was qualified. The environmental and seismic requirements used as the minimum acceptance level for the generic PRNM instruments are the same as the requirements listed in paragraphs 3.2.1 and 3.3.1.]] it is concluded that all of the generic PRNM equipment are qualified to the CGS environmental requirements in Tables 3.1 and 3.2.13 NEDO-33789 Revision 0 The qualified levels of the generic PRNM instruments are the same as the requirements in paragraphs 3.2.1, 3.3.1, and 3.4 (Tables 3.4 and 3.5, Ref. 2.1d values only). In some cases, the actual qualification testing or additional analysis supports qualification of the generic PRNM instruments and similar CGS instruments to higher levels.[II 4.1.3 CGS Requirements vs. Generic Qualification Levels 4.1.3.1 Environmental and Seismic Qualification Levels As discussed in paragraphs 3.2.1 and 3.3.1, and 4.1.2, the CGS environmental and seismic requirements at the instrument level are the same as the requirements met for the generic PRNM instrument qualification. Therefore, the generic PRNM instruments are qualified to the CGS instrument environmental and seismic requirements. [[)4.1.3.2 EMC Qualification Levels As discussed in section 3.4, the CGS EMC requirements at the instrument level are the same as the requirements met for the generic PRNM instrument qualification. Therefore, the generic PRNM instruments are qualified to the CGS instrument EMC requirements. 14 NEDO-33789 Revision 0 The evaluation in Section 4.2.2.3 addresses applicability of the EMC qualification to the CGS installed configuration.

Er Table 4.3 -- Equipment Included in EMC Testing Qty Description Part No. Bay Note 1: [[E[29 NEDO-33789 Revision 0 It is concluded that the CGS PRNM instrument installed configuration is sufficiently similar to the configuration used in the generic PRNM instrument EMC qualification tests that the results apply to the CGS PRNM instruments as installed in the CGS PRNM panels. Therefore, the CGS PRNM instruments, when installed in the panels, meet the CGS EMC requirements.
4.3 Evaluation
Conclusions Based on the evaluation documented in the previous sections of this qualification summary, it is concluded that the environmental and EMC qualification levels for the CGS PRNM equipment identified in Table 1.1 envelop the CGS "installed equipment" requirements, and are, therefore, qualified for the CGS application relative to environmental and EMC conditions. It is also concluded that the seismic qualification levels of the PRNM equipment identified in Table 1.1 and CGS panel P608 with PRNM equipment installed envelop the CGS "installed equipment" requirements, and are, therefore, qualified for the CGS application relative to seismic conditions. 11 30}}
