Regulatory Guide 1.133 (Reference

1) requires that components of the loose parts detection system in the primary system should be designed and installed to perform their functions following all seismic events that do not require plant shutdown.

Recording equipment need not function without maintenance following the specific seismic event, provided the audio and visual alarm capability remains functional. The WBT DMIMS-DX System is seismically qualified [ ]a,c in accordance with IEEE Standard 344-1987 (Reference 2).]a,c In addition to seismic qualification of the WBT DMIMS-DX System]',c the structural integrity of the WBT DMIMS-DX System [ ]aC is evaluated pac Specific details of the seismic evaluations performed for the WBT DMIMS-DX System are documented herein.Revision 0 of this document also incorporates customer comments on the preliminary version (Revision A)]ac EQ-QR-33-WBT-NP, Rev. 0 1-1 Westinghouse Non-Proprietary Class 3 Seismic Evaluation of the Digital Metal Impact Monitoring System (DMIMS-DX T¶ for Watts Bar Unit 2 WBT DMIMS-DXTM Note that the seismic qualification testing of the DMIMS-DX System was performed to IEEE Standard 344-1987 (Reference 2), however, [ ]ac,, WBT is committed to IEEE Standard 344-1975, "IEEE Recommended Practices for Seismic Qualification of Class 1E Equipment for Nuclear Power Generating Stations" (Reference 8).

The seismic test configuration is discussed in subsection 3.3.1, while the seismic requirements used during the EQ-QR-33-WBT-NP, Rev. 0 5-1 Westinghouse Non-Proprietary Class 3 Seismic Evaluation of the Digital Metal Impact Monitoring System (DMIMS-DXTM) for Watts Bar Unit 2 WBT DMIMS-DX T M test program are shown in subsection 3.3.2. Section 4.3 includes a discussion of the applicability of this testing to the WBT application a,c.Based upon the comparison of WBT requirements and test data, the supplemental testing of the DMIMS-DX [ ]a,C supports the qualification of the WBT DMIMS-DX System]ac in accordance with U.S. NRC Regulatory Guide 1.133 (Reference

1) and IEEE Standard 344-1987 (Reference
2) for the WBT application.(Last Page of Section 5)EQ-QR-33-WBT-NP, Rev. 0 5-2 Westinghouse Non-Proprietary Class 3}}
