  • TCN 004 PAGE 2 0F 6 A. TEST PURPOSE AND SCOPE
                 , ,           This test was conducted to ensure the following:

1

1. To verify that'the Safety Injection Tank (SIT) discharge check valves, (SIA-V235, SIA-V245, SIB-V215, SIB-V225) will pass flow with the RCS at normal operating pressure and tempera 6ure.
2. To verify that the Safety Injection loop check valves (SIB-V217, SIB-V227, SIA-V237, SIA-V247) will pass flow with the RCS at normal operating pressure and temperature.
3. To verify that the RCS loop hot leg check valves (SIB-V532, SIA-V522) will pass flow with the RCS at normal operating pressure and temperature.

B. COMPLEMENTARY TESTS This precore hot functional test satisfied the following licensing commitments:

1. Verified flow through the safety injection loop check valves by lining up to the CVCS charging pumps to discharge into the safety injection discharge header. (Source Document CESSAR 14.2.12.2.12)
2. Demonstrated the operability of emergency core cooling system to show the operability of the check valves along the safety injection l

discharge path at operating temperatures. (Source Document ASME X XI IWV-3520)

3. Demonstrated the operability of the check valves for the high pressure safety injection system hot operating condition flow test. (Source Document Reg. Guide 1.79, Rev.'O, C.3.A(2)

(Source Document CESSAR 14.2.12.2.12)  ; i t C. TEST DESCRIPTION ' The four RCS Loop Check Valves (SIA-V237, SIA-V247, SIB-V217, SIB-V227) were tested as follows:

1. Maintained RCS at normal operating temperature and pressure.
2. Two charging pumps were used to maintain an 88 gpm output. ,
3. Maintained RCP seal injection flow at g-eater than 40 gpm through the
                                                                                                                      ~

seal injection line.

4. Established conditions for a parallel flow path ,through the HPSI header.
5. Established flow through the RCS Loop Check Valve via the HPSI header by jogging open the associated HPSI Header Control Valve (SIA UV-637, -647, -617, and -627). Recorded the RCS pressurc, HPSI Header Pressure, and Charging Header flow upon opening and closing the HPSI Header Control Valve.
6. Verified flow through the loop check valves when charging flow decreased and HPSI Header Pressure increased to greater than RCS pressure. .
7. Depressurized the HPSI line to equalize it with the Safety Injection  !

l Tank. Recorded both SIT pressure and HPSI pressure. m__ _.___.__._.--me.

l _ The Safety Injection Tank Discharge Check Valves (SIB-V715 and -V225, and GIA-V235 and -V245) were tested as follows:

1. Maintained RCS at normal operating temperature and pressure.
2. Recorded SIT level and pressure.
3. Maintained HPSI header pressure of less than 620 psig.
4. Established valve lineup to allow depressurization to the

[ Reactor Drain Tank, as per TCN 003. 1 . S. Opened the discharge header drain valve and monitored the SIT i. level for decrease.--Closed the valve when a-level decrease was - observed.

6. Recorded the SIT leve'l and pressure. A decrease in both parameters indicated that the check valve passed flow.

The two RCS Loop Hot Leg Check Valves (SIA-V522 and SIB-V532) were tested as follows:

1. Maintained RCS at normal operating temperature and pressure.
2. Recorded RCS Pressure, HPSI Header pressure, and Charging Header l

Flow.

3. Opened HP Long Path Recirculation valve (SIA-HV-640 or SIB-HV-509).

4 Jogged Open HPSI Header Centrol Valve (SIC-HV-321 or SID-HV-331) to pressurize the line to the check valve being tested.

5. Closed HPSI Header Control Valve (SIC-HV-321 or SID-HV-331) .
6. Recorded RCS pressure, HPSI Header Pressure and Charging Header flow.
7. Verified flow through check valve (SIA-YI22 or SIB-V532) by observing a decrease in charging flow and an increase in HPSI header pressure to slightly greater than RCS pressure.
8. Closed HP long path recirculation valve (SIA-HV-604 or SIB-HV-509).
