SQNP SPECIAL TEST 1 Page 1 of 1 Rev. 0 NATURAL CIRCULATION TEST TEST DESCRIPTION The test will be initiated by simultaneously tripping all reactor coolant pumps while at 3% power. The transient response will be monitored and establishment of natural circulation verified. Core exit thermocouples will be monitored to determine the core flow distribution. After stable conditions have been established, forced circulation will be reestablished.

B. M/D Power Monitor Program

1. P~ -- Conversion Constant Adjustment.

a) The output of the REF primary calorimetric will give a percent I

power output; this output must be input to the M/D Power-i Monitor Program so that the program output will be in percent power and equal to the primary calorimetric output.

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. After the output has been calibrated to be equal to the REF primary calorimetric it will be rerun up to once every 2 minutes or as necessary to. continuously monitor core power.

C.1 Use two DVMs and measure the voltage at the test points speci-fied for each loop as rapid as possible.

C.2 Calculate the AT; multiply that AT by the specific heat and the Westinghouse best estimate flow rate of the core average temperature (Table C-1). (Special Test No. 9 uses wide range AT so a correction factor is required to compensate for pump heating, refer to Appendix D of ST-9A).

PART C: Using Thermocouples 1

j The incore thermocouples can be used as an indication of both core flow distribution and power shif ts during natural circulation.

Prior to running a thermocouple map or trending the eight quadrant tilts (four center lines and four diagonal tilts) the following j should be verified:

i K0701-K0765 = 1, for the flow mixing factors K5501 = 0, Indicates the measured core AT is unreliable K0791 = 0.075, Core bypass flow fraction <

K5010 = 8, Tells thermocouple program how many readings of thermocouples are required for averaging before calculation is done. This in turn sets the run-ning frequency of the Thermocouple Averaging

, Program at 1, 2, . . . . X 8 seconds or 64 seconds for us.

The thermocouple programs breaks the core down into eight quand-rants--four centerline and four diagonal quandrants (see Figure C-1).

Quadrants 1-4 can be directly correlated with the excore detectors .

but quadrants 5-8 cannot.

The quadrant tilte are indicative of power shifts and should be trended at approximately a 2-minute frequency. The following addressable values are the quadrant tilts:

2 U1160 3 U1161 4 U1162 5 i'1151 6 U1152 7 U1153 8 U1154 l A Short Form Hap should be run periodically or upon request from the test engiucer as an indication of core flow distribution. It should be put on the Utility Typewriter if possible. The P-250 Operator's Ccusole Reference Manual provides instructions for ob-taining thermocouple maps.

The trend output and Short Form Haps should be attached to this procedure at the end of the test.

SQNP SPECIAL TEST 1 Page 1 of 11 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 por-tion 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 auto-matically. (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 pancis in R-47 and R-50.

NOTE: These jumpers will be specially made for this purpose and installed by an instrument mechanic.

. 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 34 m
