WESTINGHOUSE CLASS 3 SECTION 2 - QUALIFICATION BY TEST O

2.0 TEST PLAN Isolation relay seismic tests were performed at the Wastinghouse seismic test facility at Large, Pennsylvania.

2.1 Equipment Description P

The ATWS System Actuation Circuitry (AMSAC) system is a microprocessor based system that senses a potential loss of normal feedwater or a loss of electrical load. This system is not safety-related. However, it provides output signals to safety-related systems. The output relays that isolate the nonsafety signals of the microprocessors from the safety related systems are the components that are safety-related.

AMSAC is installed in a floor mounted cabinet. This cabinet and the devices it contains must maintain structural integrity during a design basis seismic d event. The cabinet and some devices it contains are qualified on the basis of testing reported in References 1 and 2'.

The isolation relays and sockets that were seismically tested are shown below, l

2.4 Connections Tha connections used for the relay test are described in Reference 3. Ol 2.5 Aging Thermal aging was acdressed by analysis and the relays were mechanically aged as described in Reference 3.

l 2.6 Service Conditions Simulated By the Tests l

The service conditions simulated by the relay test program were seismic l conditions. The required response spectra for the AMSAC cabinet with relays installed are shown in Figures 2 and 3. Figure 2 is the required response i spectrum for cabinet enntaining both unrestrained nonlatching and latching relays in the same cabinet. Figure 3 is the required response spectrum for a cabinet with unrestrained nonlatching relays only or restrained nonlatching I and latching relays in the same cabinet.

2.7 Measured Variables Electrical isolation between the coil and contacts of the relay was monitored. ,

The coil to contact leakage and contact bounce of the normally open and normally closed contacts of the relays were monitored. These were the only parameters of significance to this test.

2.8 Test Sequence Preferred This section identifies the preferred test sequence as specified in WCAP-8587.

2.9 Test Sequence Actual This section identifies the actual test sequence which, constitutes the O qualification program for the AMSAC isolation relays. The actual test sequence for the Plant Safety Monitoring System (PSMS) devices is described in Reference 4. The actual sequence test for the cabinet is described in Reference 2.

The DBE is simulated by the Seismic Test sequence of Section 2.9.1. The HELB Tests (Section 2.8.6 and 2.8.7) have been excluded because the AMSAC system is not exposed to a harsh environment due to its location. The abnormal extremes were addressed by analysis. The aging of the isolation relays was addressed by analysis.

2.9.1 Seismic Test Sequence 2.8.1 2.8.2 2.8.5 2.8.8 2.9.2 Environmental Test Sequence Environmental test sequence for the relays was accomplished by analysis.

2.9.3 Aging Test Sequence Aging is addressed by analys'is as described in Subprogram C of Appendix B to WCAP-8587 and reported in Reference 3.

WEST!NGHOUSE CLASS 3 2.10 Test Data 2.10.1 Objective O\ l I

The objective of the relay test program is to demonstrate, employing recommended practices of Reg. Guide 1.89 (IEEE 323-1974) and Reg. Guide 1.100 (IEEE344-1975), the capability of the AMSAC isolation relays to complete their safety function ac described in EQDP Section 1.7. The test objectives for PSMS devices are detailed in Reference 4. The test objectives for the cacinet are detailed in Reference 2.

2.10.2 Equipment Tested 2.10.2.1 Relay environmental qualification was by analysis as described in Reference 3.

2.10.2.2 Relay seismic tests reported in Reference 3.

2.10.2.3 PSMS seismic tests reported in Reference 1. Westinghouse Standard Seismic Cabinet test are reported in Reference 2.

2.10.3 Test Sumary 2.10.3.1 Relay Tests l

l Contact-to-coil leakage current, and voltage across the normally open and j normally closed contacts of the relays were monitored before, during, and after the seismic simulations.

I 2.10.3.2 Relay Seismic Tests i The single design basis event capable of producing an adverse environment at the equipment location is a seismic event. The seismic testing reported in i Reference 3 was completed on relays that had been mechanically aged. The 9

relays were subjected to simulated triaxial multifrequency testing as suggested in IEEE 344-1975. This testing demonstrated that the relays do maintain isolation between the coil and contacts during a simulated design basis seismic event.

The relay normally closed contacts experienced bounce in excess of 2 milliseconds. The results of contact bounce do not pose a significant safety concern for their application within the AMSAC System.

2.10.3.3 PSMS Device Seismic Tests The results of the seismic testing performed on PSMS devices that are part of the AMSAC system are detailed in Reference 1.

2.10.3.4 Cabinet Seismic Tests The results of cabinet seismic testing are detailed in Reference 2.

f 2.11 Conclusions Based upon the results reported in References 1, 2, and 3, the AMSAC system mounted in the Standard Seismic Cabinet is qualified for operation in mild environments.

l SECTION 4 - QUALIFICATION BY ANALYSIS O  ;

4.1 Environmental The environmental qualification was by analysis at Westinghouse NSID, -

Monroeville, PA.  !

The environmental qualification of the isolation relays is based upon an J

analysis of the Arrhenius properties of the non-metallic materials of the relays and mounting sockets.

The environmental conditions were addressed by analysis of the Arrhenius properties of the nonmetallic components of the isolation relays.

AMSAC is located where it will not experience adverse environments resulting from a high energy line break. The aging characteristics of the relays were evaluated by analysis of the nonmetallic materials in the relays. The results of the analysis are reported in Reference 3.

4.2 Seismic The cabinet which contains the AMSAC circuitry was qualified by similarity analysis. The analysis was performed using the criteria discussed in Referenes 3. The analysis demonstrated that the cabinet will maintain l structural integrity during a design basis event (Figure 3).

The structural integrity of the mounting of AMSAC devices not included in the Reference 1 testing was evaluated. The analysis was performed as discussed in Reference 3. The analysis demonstrated the strutural integrity of the device mounting when the AMSAC cabinet is subjected to a design basis event (Figure 3).
