I FORCED CIRCULATION C00LDOWN Test Description This test will generate a correction factor which will be applied to the excore detector outputs in order to compensate for PV downcomer shadowing during a cooldown from ~ 550 F to ~ 450 F.

The RCS will initially be ~ 3% power, in forced circulation. p cooldown via steam dumps will be initiated and continue until avg is approximately 450 F.

During the cooldown primary side ca'arimetrics will be performed, movabic detector integral power calculations performed, and excore detector data obtained simultaneously.

Power should be maintained as. constant as possible using the results 4

of the primary side calorimetric and integral power calculations.

Data reduction will be on a continuous basis.

Af ter reaching ~ 450 F the plant will be allowet' to heat up and additional data will be obtained.

i Data reduction will average the cooldown and heatup data and generate an excore detector indicated power correction factor as a function of the average cold leg temperature.

SQNP SPECIAL TEST 9A Page 6 of 12 Rev. 0 3.0 PRECAUTIONS, LIMITATIONS, AND ACTIONS 3.1 Do not exceed 5% RTP.

Caution should be used in maintaining the desired power level because of flux shadowing of the excore detec-tors. Don't depend on the excore detectors. Use as many methods as possible to determine actual core power.

3.2 During the cooldown the isothermal temperature coefficient.will be small but may be of either polarity.

Care should be taken when changing reactivity using control rods or boron concentration because at some point the temperature cofficient polarity could change.

4 3.3 Maintain control bank D at ~ 160 steps if possible. This same suggested minimum limit will be used during the natural circula-tion test. This height will minimize the effect of rod shadewing of the excore detectors and insure uniformity between forced and natural circulation test.

3.4 When operating below 525 F, ensure control bank D position remains at 2 100 steps.

Should this limit be reached during the cooldown boron concentration will have to be increased.

3.5 When testing with the reactor coolant in the low temperature range of 450 F to 500 F, maintain the lithic concentration at 2.0 to 2.2 ppm, the upper part or the specified lithic range.

This is especially necessary if high boric acid concentrations i

(~ 1000 ppm) are also being used.

3.6 Ensure the differential pressure across the steam generators remains below 1600 psig.

2.

Power Monitoring a) The M/D Power Monitor Program will calculate the integral power as seen by one pass of 5 or 6 detectors.

If no value has been entered into (K0864) enter 0.25.

For power determination, obtain a partia] core flux map as per TI-53.

The M/D's need not be withdrawn between passes, and passes may be repeated as often as a po'wer determination is required.

N9TE: The calculated power (UO906) is printed after each pass and may be trended by the P-250 if desired. The individual detec-tor normalized integrals are also printed.

SQNP SPECIAL TEST 9A Page 1 of 13 Rev. 0 APPENDIX E Safeguard Blocking Procedure The 'first step blocks automatic initiation of a safety injection. The safety injection alarm, manual S.I handswitch, and the reactor trip portion of the protection logic will remain in operation.

If conditions exist that would normally initiate a safety injection; (1) the safety injection alarm will initiate telling the operator that the condition exists and what the problem is.

(2) a reactor trip will take place automatically.

(3) a safety injection can be initiated manually from the switch in the control room if conditions warrant.

1.

Install temporary jumpers and temporary alteration control tags to logic cards A216, test point 1, to the logic ground on the logic test panels in R-47 and R-50.

Procedure for blocking automatic actuation of a safecy injection on high steamline Delta-P.

This block will prevent a reactor trip from occuring during the natural circulation tests from high AP caused by degraded test conditions.

(This block will also defeat all AP S.I. alarms.)

2.

Verify status lights 1-XX-55-6B/1, 2, 3, 4, 25, 26, 27, 28, 50, 51, 73, 76 are all clear prior to starting blocking procedure.

CAUTION:

In the next step, and all following steps in which a voltage is being applied to the indicated terminals, ensure the applied voltage is of the same polarity as the terminals. This check should be.done for every step that a voltage' source is applied.

Failure to apply the correct polarity will ground the rack power supply.

(This problem can be avoided if only the hot wire from the voltage source in the rack is applied to the first terminal indicated in each step [the lower numbered terminal]. The 33

SQNP SPECIAL TEST 9A Page 2 of 13 Rev. 0 APPENDIX E ground will already be made up through the trip switch). The wire on the rack side of the terminal block must be lifted and taped for the terminal point where the jumper wire is connected.

The following bistables should be returned to their normal setpoints indicated on the calibration card for the particular bistable. (30.0 +.2MA)

Remove the temporary alteration control tags after the recalibration.

NOTE: These calibrations require 2 IM's per calibration.

The same individuals may only calibrate 2 of the instruments. The other instruments must be calibrated by other individuals.
