WESTINGHOUSE CLASS 3 SECTION 2 - QUALIFICATION BY TEST 2.0 TEST PLAN Isolation relay seismic tests were performed at the Westinghouse seismic test '

facility at Large, Pennsylvania.

2.1 Equipment Description O The ATWS Mitigating 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 celays that isolate the nonsafety signals of the microprocessors from the safety-ielated systems are the components that are safety-related.

AMSAC microprocessor circuitry is installed in a floor mounted cabinet while f the isolation relays are installed in a wall mounted enclosure. The cabinets  !

and the devices they contain must maintain structural integrity during a I design basis seismic event. The AMC0 Cabinet and Relay Enclosure are qualified on the basis of testing reported in References 1 and 2 and the similarity analysis given in Reference 3.

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

RELAY PART NUMBER SOCKET PART NUMBER Latching 405A11H01 1856E86H11 O Noniatching 405A10H01 1856E86H10 Reference 3 describes the results of the relay seismic testing.

2.2 Number Tested Three latching relays and three nonlatching relays and their mounting sockets were tested in this program.

O 4s&8R/236R880s17.50 4

WESTlNGHOUSE CLASS 3 2.3 Mounting Reference 3 describes the mounting configuration for the relays tested.

O 2.4 Connections The connections used for the relay test are described in Reference 3.

2.5 Aging Thermal aging was addressed by analysis and the relays were mechanically aged as described in Reference 3.

2.6 Service Conditions Simulated By the Tests The service conditions simulated by the relay test program were seismic conditions. The AMSAC system consists of an AMCO Cabinet containing all circuitry except for the Struthers-Dunn relays: the required response spectrum for the cabinet is shown in Figure 2. The isolation relays are located in a wall mounted Hoffman Relay Enclosure. Figure 3 is the required response spectrum for the enclor,ure when it contains unrestrained noniatching and latching relays. Figure 4 is the required response spectrum for the enclosure containing unrestrained nonlatching relays only or restrained noniatching and latching relays.

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 (see Reference 3).

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.

The actual test sequences used to qualify the AMC0 Cabinet and the Hoffman Relay Enclosure are described in References 1 and 2 respectively. l 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 i by analysis.

WESTENGH0VSE CLASS 3 2.10 Test Data 2.10.1 Objective O

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 (IEEE 344-1975), the capability of the AMSAC isolation relays to complete their safety function as described in E00P Section 1.7. The test objectives for the AMC0 Cabinet and Hoffman Relay Enclosure are detailed in References 1 and 2.

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

2.10.2.2 Relay seismic tests reported in Reference 3.

2.10.3 Test Summary 2.10.3.1 Relay Tests Contact-to-coil leakage current, and voltage across the normally open and normally closed contacts of the relays were monitored before, during, and after the seismic simulations.

2.10.3.2 Relay Seismic Tests The single design basis event capable of producing an adverse environment at the equipment location is a seismic event. The seismic testing reported in Reference 3 was completed on relays that had been mechanically aged. The relays were subjected to simulated triaxial multifrequency testing as g suggested in IEEE 344-1975. This testing demonstrated that the relays do W maintain isolation between the coil and contacts during a simulated design basis seismic event.

O 4ssiv23smssesu so 7

WESTINGHOUSE CLASS 3 The relay's 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 AMSAC Device Seismic Tests The results of the seismic testing performed on devices in the AMC0 Cabinet are detailed in Reference 3.

2.10.3.4 Cabinet and Relay Enclosure Seismic Tests The results of cabinet and relay enclosure seismic testing are detailed in References 1 and 2. l 2.11 Conclusions Based upon the results reported in References 1, 2, and 3, the AMSAC system mounted in the AMC0 Cabinet and Hoffman Relay Enclosure is qualified for integrity and the isolation relays will maintain their required performance

WESTINGHOUSE CLASS 3 SECTION 4 - QUALIFICATION BY ANALYSIS V I 4.1 Environmental I Im s

") The environmental qualification was by analysis at Westinghouse HSID, Monroeville, PA.

The environmental qualification of the isolation relays is based upon an

[JL i 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.

V] ,

4.2 Seismic The cabinet and Relay Enclosure which contain the AMSAC circuitry were qualified by similarity analysis. The analysis was performed using the criteria discussed in Reference 3. The analysis demonstrated that the cabinet will maintain structural integrity during the design basis event shown in Figure 2 while that for the Hoffman Relay Enclosure is shown in Figures 3 and 4.

(V^)

The structural integrity of the mounting of AMLAC devices was evaluated. The analysis was performed as discussed in Reference 3. The analysis demonstrated j x, the structural integrity of the device mounting when the AMSAC cabinet is

{V subjected to a design basis event (Figure 2).
