PEASE III TEST PRCCEDURE 501-7-001 C00LDOWN CAPA3ILITY OF THE CHARGING AND LETDOWN SYSTEM 1.0 Pur;cse This procedure contains the information necessary to verify plant performance capabilities and provide operator experience and training in the following condition:

1.1 Determination of the CCOLDOWN CAPA3ILITY OF THE CEARGING AND LETDOWN SYSTEM with all three S/G's isolated and one RCP in operation.

2.0 Initial Conditions 2.1 T

is approximately 535'F.

The Steam Dump i$V8perating (or available) to maintain T"Y" in

/

l the Steam Pressure Mode.

2.2 Pressurizer pressure is being maintained

/

at approximately 2235 psig by automatic operation of the Pressurizer Pressure Control System.

2.3 Pressurizer level is being maintained at

/

approximately 22% by automatic operation of the Pressurizer Level Control System.

2.4 The S/G's are being maintained at approxi-

/

mately 33%.

The Main Feedwater or AFW System is operating (or available) to maintain S/G levels.

2.5 23 RCP is running.

/

l 2.6 The CVCS is in a normal at-power lineup.

(

/

2.7 Excess letdown is available for operation.

l

/

t 2.8 Both shutdown banks are fully withdrawn.

/

2.9 RCS Soren concentration is high enough to

/

provide sufficient Shutdown Margin at 450 F 1

Rev. O

501-7-001 2.10 The Core Subcooling Monitor is operable.

k

/

1 2.11 Temporary instrumentation has been installed

/

as required by Appendix A of this procedure.

4 2.12 The computer trend printer is set up to

,l

/

monitor the parameters specified in Appendix B l

of this procedure.

2.13 All test equipment to be used during the

/

performance of this procedure is operational and in calibration, as verified on the Test Equipment Record, Data Sheet 1 of this procedure.

2.14 The Shift Supervisor has been notified of the

/

impending performance of this procedure.

2.15 S/G chemistry is in a condition such that

/

blowdown may be isolated for the duration of the test.

2.16 Prior to commencing this test, record the

/

following information (as applicable) on each Recorder Strip Chart.

Test Procedure Number Recorder Number Time and Date Chart Speed Scale of each Pen Input to each Pen 3.0 Precautions and Limitations 3.1 The difference in Boron concentration between the RCS and Pressurizer should not exceed 50 ppm.

Use Pressurizer Spray to equalize concen-tration.

3.2 Monitor and record Source Range count rate on Data Sheet 4 every 15 minutes.

Any unexplained increase in count rate by a factor of two is grounds for test termination and investigation for cause.

2 Rev. O

501-7-001 4.0 Instructions 4.1 Record the "d me on the recorder charts in the

/

instrument rack area and/or Control Room and start the recorders at an appropriate speed determined by the Test Supervisor.

4.2 Record the initial plant conditions on Data

/

Sheet 2.

4.3 Close the Main Steam Line 2A (B, C) upstream

/

drain pot to Aux Steam Condensate Tank isolation valves Q2N11V006A (B, C) and Q2N11V008A (B, C).

4.4 Shutdown the S/G Blowdown System, if in

/

operation, using FNP-2-SOP-16.1.

4.5 Stop 2A and 2C RC?'s, if operating.

/

4.6 Adjust T to 535*F 2*F using the Steam ave

/

Dump.

4.7 Stop feeding the S/G's and shutdown the AFW

/

System using FNP-2-SOP-22.0 or the Main Feedwater System using FNP-2-SOP-21.0.

4.8 Verify that S/G 23 Atmospheric Relief Valve

/

is in AUTO and set for 1035 psig.

4.9 C1cse all six MSIV's.

/

4.10 Verify that the Pressuriser Level Control

/

System is in AUTO.

4.11 Increase letdown flow to maximum using

/

FNP-2-SOP-2.1.

NOTE T

may increase or decrease decending odVIhe charging temperature and "flowrate and RCS ambient losses.

4.12 Maintain the flow conditions established in

/

step 4.11 for 30 minutes, or until T decreases to 525*F, or until T incFeases to"535 F, whichever comes :1:sIY" Record the information required in Data sheets 3 and 4.

3 Rev. O

501-7-001 W

CAUTION If T reaches 545 F, proceed directly tosfd$4.15.

4.13 After 30 minutes or when T reaches 525 F reduce letdown flow to minfEdm using FNP-2-SOP-2.1.

/

CAUTION Maintain 6 to 13 gym seal injection flow to 23 RCP.

4.14 Maintain the flow conditions established in

/

step 4.13 for 30 minutes or until T decreases to 520*F, or until T increases t8V545*F, whichever i:omes firsgye Record the information required in Data Sheets 3 and 4.

4.15 Stop the recorders and trend printer after

/

the test is completed and restore plant conditions using the following steps.

4.16 Re-establish normal Charging and Letdown

/

conditions.

4.17 If necessary restore normal levels in all

/

three S/G's with the AFW System using FNP-2-SOP-22.0.

4.18 Verify that the Steam Dump is set up for Steam

/

Pressure Mode operation using FN?-2-SOP-18.0.

4.19 Cpen the MSIV's using FNP-2-SOP-17.0.

4.20 If required, restore S/G Blowdown using

/

FNP-2-SOP-16.1.

4.21 Notify the Shift Supervisor that this Test

/

is complate.

4 Rev. O

501-7-001 4.22 Verify that all Data Sheets associated with

/

this procedure are complete and signed-off (where required).

4.23 Attach all relevant printouts and strip charts

/

to this procedure and remove the temporary instrumentation if this concludes Natural Circulation testing.
