ITAAC Completion Description Testing and inspections are performed to, verify that the valves identified in Combined License (COL) Appendix C Table 2.2.4-3(Attachment A and Attachment B) close after a signal is generated by the Protection and Safety Monitoring System (RMS), that safety-related displays identified in COL Appendix C Table 2.2.4-1 (Attachment C)can be retrieved in the Main Control Room (MCR), that controls in the MCR operate to cause the remotely operated valves identified in COL Appendix C Table 2.2.4-1 (Attachment D)to perform active safety functions, and the remotely operated valves identified in COL Appendix C Table 2.2.4-1 (Attachment E)as having RMS control perform the active function identified in the table after receiving a real or simulated signal from the RMS. This ITAAC also verifies selected Steam Generator System (SGS) valves (Attachment F) close within the prescribed time after receipt of an actuation signal, that each Motor-Operated Valve(MOV)changes position as indicated in COL Appendix C Table 2.2.4-1 (Attachment G) under preoperational test conditions, and that after a loss of motive power, each remotely operated valve identified in COL Appendix C Table 2.2.4-1 (Attachment H)assumes the indicated loss of motive power position.

i) The valves identified in Table 2.2.4-3 close after a sional is Generated bv the RMS.

Testing is performed in accordance with Unit 3 and Unit 4 preoperational test procedures 3-TOS-ITRR-501, 4-TOS-ITRR-501 (References 1 and 2), and Unit 3 and Unit 4 component test packages SNCXXXXXX and SNCYYYYYY (References 3 and 4). These component test packages utilize B-GEN-ITRCI-039(Reference 5) to direct the performance of test procedures to verify that the valves identified in Attachment A and Attachment B close after a signal is generated by the RMS.

Testing in references 1 and 2 is done to verify the valves in Attachment B close after a signal is generated by the RMS. Testing in reference 1 and 2 is performed by verifying the Main Turbine Stop Valves and Control Valves are open. The RMS reactor trip hand switch is placed to trip and the Main Turbine Stop and Control valves are verified to close locally. This testing confirms that the valves in Attachment B close after a signal is generated by the RMS.

U.S. Nuclear Regulatory Commission ND-19-0950 Enclosure Page 4 of 15 Reference 5 directs tfie performance of 3/4-l\/ITS-OTS-10-001 (References 6 and 7)and verifies the valves in Attachment A are open. A manual RMS Steamiine Actuation signal is generated using a hand switch in the MGR and the valves in Attachment A are verified to close locally.

This testing confirms that the valves in Attachment A close after a signal is generated by the RMS.

The combination of these tests for Unit 3 and Unit 4 verifies the valves identified in Table 2.2.4-3 close after a signal is generated by the RMS.

Safetv-related disolavs identified in Table 2.2.4-1 can be retrieved in the MGR.

The inspection is performed in accordance with Unit 3 and Unit 4 component test procedures SNG922107 and SNGYYYYYY (References 8 and 9)to verify that the safety-related displays identified in Attachment G can be retrieved in the MGR.

The component test is conducted at the MGR RMS Visual Display Units(VDUs)and verifies the safety-related displays in Attachment G can be retrieved in the MGR. Each valve and indication listed in Attachment G is located on the VDUs and verified to display. This confirms that all the safety-related displays identified in Table 2.2.4-1 can be retrieved in Unit 3 and Unit 4 MGR.

Gontrols in the MGR operate to cause the remotelv operated valves to perform active safetv functions.

Testing is performed in accordance with Unit 3 and Unit 4 component test procedures SNG922107 and SNGYYYYYY (References 8 and 9)to verify that controls in the MGR operate to cause the remotely operated valves in Attachment D to perform active safety functions.

Testing is conducted at an operator work station in Unit 3 and Unit 4 MGR to verify the valves identified in Attachment D as being remotely operated and having active safety functions are stroked open and closed from the MGR. The valve positions are locally verified and verified in the MGR. This confirms that controls in Unit 3 and Unit 4 MGR operate to cause the remotely operated valves to perform active safety functions.

i) The remotelv-ooerated valves identified in Table 2.2.4-1 as havino RMS control oerform the active function identified in the table after receiving a sional from the RMS.

Testing is performed in accordance with Unit 3 and Unit 4 component test packages SNGXXXXXX and SNGYYYYYY (References 3 and 4)to confirm the remotely-operated valves identified in Attachment E as having RMS control perform the active function identified in the table after receiving a signal from the RMS.

Testing is performed in accordance with references 3 and 4 and utilizes B-GEN-ITRGI-039 (Reference 5)to direct the performance of test procedures 3/4-GEN-OTS-10-002(References 10 and 11), 3/4-GEN-OTS-10-004(References 12 and 13), 3/4-SGS-OTS-10-003(References 14 and 15^ and 3/4-SGS-OTS-10-004(References 16 and 17). The valves listed in Attachment E are verified to be Open and testing is performed by references 10 through 17 utilizing the RMS Maintenance and Test Ranel(MTR)to generate a RMS output signal. The valves in Attachment E are verified to close by MGR indication and locally at the valves when the RMS output signal is generated.

U.S. Nuclear Regulatory Commission ND-19-0950 Enclosure Page 5 of 15 The combination of these tests confirm the remotely-operated valves identified in Table 2.2.4-1 as having RMS control perform the active function identified in the table after receiving a signal from the RMS for Unit 3 and Unit 4.

ii) These valves close within the followino times after receipt of an actuation signal:

V027A/B <44 sec V040A/B. V057A/B < 5 sec V250A/B <5 sec Testing is performed in accordance with Unit 3 and Unit 4 component test packages SNCXXXXXX and SNCYYYYYY (References 3 and 4)to confirm the following valves close within the following times after receipt of an actuation signal; V027A/B < 44 sec; V040A/B, V057A/B < 5 sec; V250A/B < 5 sec (Attachment F).

Testing is performed in accordance with references 3 and 4 and utilizes B-GEN-ITRCI-039 (Reference 5)to direct the performance of test procedures 3/4-GEN-OTS-10-002(References 10 and 11), 3/4-GEN-OTS-10-004(References 12 and 13), 3/4-SGS-OTS-10-003(References 14 and 15), and 3/4-SGS-OTS-10-004(References 16 and 17). The valves in Attachment F are verified to be Open, a trend is established to record valve timing information, and testing is performed by references 10 through 17 utilizing the RMS MTR to generate a RMS output signal.

The valves in Attachment F are verified to close, the valve closure time is recorded in the test and valve closure time is summarized in Attachment F.

This testing confirms that these valves close within the following times after receipt of an actuation signal: V027A/B < 44 sec; V040A/B, V057A/B < 5 sec; V250A/B < 5 sec.

ill) Each motor-operated valve chances oosition as indicated in Table 2.2.4-1 under preoperational test conditions.

Testing is performed in accordance with Unit 3 and Unit 4 preoperational test procedures 3-SGS-ITRR-502 and 4-SGS-ITRR-502(References 18 and 19)to verify each motor-operated valve changes position as indicated in Attachment G under preoperational test conditions.

The testing ensures the Reactor Coolant System (RGB)is at the 557°F plateau to establish the secondary system conditions required for this preoperational testing. The steam generator power-operated relief valve is opened from the MGR,and SGS-RL-V027A (Rower-operated Relief Valve Block MOV Steam Generator 01) is closed and locally verified to be closed. This testing is repeated for SGS-RL-V027B (Rower-operated Relief Valve Block MOV Steam Generator 02).

Startup feedwater flow is verified to be 200 gpm or greater, and SGS-RL-067A (Startup Feedwater Isolation MOV)is closed and locally verified to be closed. This testing is repeated for SGS-RL-V067B (Startup Feedwater Isolation MOV).

The test results verify that for Unit 3 and Unit 4 each motor-operated valve changes position as indicated in Table 2.2.4-1 under preoperational test conditions.

After loss of motive power, each remotelv operated valve identified in Table 2.2.4-1 assumes the indicated loss of motive power position. Motive power to SGS-RL-V040A/B and SGS-RL-V057A/B is electric power to the actuator from plant services.

U.S. Nuclear Regulatory Commission ND-19-0950 Enclosure Page 6 of 15 Testing is performed in accordance with Unit 3 and Unit 4 component test procedures SNC922110 and SNCXXXXXX (References 20 and 21)to demonstrate that after a loss of motive power, each remotely operated valve identified in Attachment H assumes the indicated loss of motive power position. Motive power to SGS-PL-V040A/B and SGS-PL-V057A/B is electric power to the actuator from plant services (plant electrical power to the operating solenoids).

The component test configures and documents the air operated valves are in the Open position, removes power to the solenoid valve supplying air to the valve actuators which removes motive power from the valves. The air operated valves are locally verified to fail to their loss of motive power position (closed). The motor-operated valves(MOVs)are configured to the Open position, power is removed from the motor and the valves are verified to fail to their loss of motive power position (As-ls). The hydraulic/pneumatic valves(SGS-PL-V040A/B and SGS-PL-V057A/B) are configured to the Open position, power is removed from the actuator (electrical power to the operating solenoids), and the valves are verified to fail to their loss of motive power position (As-ls).

The test results verify for Unit 3 and Unit 4 that after loss of motive power, each remotely operated valve identified in Table 2.2.4-1 assumes the indicated loss of motive power position.

Motive power to SGS-PL-V040A/B and SGS-PL-V057A/B is electric power to the actuator from plant services.

The completed test results (References 1 through 21) are available for NRC inspection as part of Unit 3 and Unit 4ITAAC Completion Packages(References 22 and 23).
