5.0 LIMITS AND PRECUATIONS 5.1 During the conduct of this test the Test Supervisor will make determinations relating to the amount of data being recorded (i.e. speed of recorders, collecting of data, etc.).
/
5.2 Avoid rapid or sudden changes in hteam pressure or feedwater flow.
/
5.3 Maintain less than 97 psid pressure between any two steam lines and greater than 675 psig in each Steam Generator.
/
5.4 During the conduct of this test the Shift Supervisor will make determinations relating to the safety of the plant and terminate the test when plant safety or equipment is jepordized.
/
O
ZPT-9.2 PAGE 7 REV. NO. O DATE 6/6/82 6.0 TEST METHOD 6.1 verify that Source Range Channels 31 and 32 are selected on NR-45.
__]
6.2 Place Pressurizer spray valv'es PCV-444C and PCV-444D in MANUAL and close the valves.
/
6.3 Verify RCP seal injection is between 6 and 12 gpm per pump and to tal flow is less than 33 gpm.
/
6.4 Place Pressurizer Level Control in MANUAL and match the charging plus seal injection flows to the letdown and ' seal return flows.
/
()
NOTE:
Pressurizer level will now vary with the RCS heatup/cooldown.
6.5 Tb simulate the loss of onsite and of fsite AC power perform the following:
6.5.1 Turn the two steam dump interlock switches to the OFF RESET position and release.
/
6.5.2 Place the three SD/PWR relief switches to the PWR RLF position.
/
i I
6.5.3 Place the three PWR RELIEF SETPT controls in MANUAL and adjust the setpoints to maintain a steam pressure of approximately 1092 psig.

DATE 6/6/82 6.5.4 Place the steam dump CNTRL in MANUAL and reduce the signal output to zero.
/
NOTE:
Control of steam pressure is now via the PORVs.
6.5.5 Place all pressurizer heater groups in OFF.
/
6.5.6 Start the TDEFW pump as per SOP-211.
/
6.5.7 Verify S/G Blowdown is secure.
/
6.5.9 Place the two MDEFP switches in the pull-to-lock position.
6.5.9 At the HVAC panel stop XFN-83 A-VL and XFN-83 B-VL by placing switches EFP CLG FAN A and EFP CLG FAN B to OFF.
/
6.5.10 Monitor the Turbine Driven Emergency Feedwater Pump for increasing temperature and vibration throughout the duration of this test with no HVAC available.
/
6.5.11 Place the TDEFP to S/G A, B, C switches in MANUAL and fully open TDEFP to S/G A, B,
