SQNP SPECIAL TEST 7 Page 1 of 21 Rev. 0 1.0 OBJECTIVES The objectives of this test are:
1.1 To demonstrate that following a loss of all onsite and offsite power, including the emergency diesel generators, the decay heat can be removed by natural circulation using the auxiliary feed-water system in the manual mode.
l 1.2 It will be verified that hot standby conditions can be maintained by manual control of the auxiliary feedwater system.
1.3 It will also be verified that. critical plant operations can be per-
) formed using emergency lighting, that the 125-volt vital battery
- has the ability to supply the 125-volt vital AC and that certain equipment areas do not exceed maximum design temperature.
1.4 To provide operator training, all operating shifts will perform this test.

3.0 PRECAUTIONS 3.1 Maintain reactor coolant pump seal and thermal barrier different-ial pressure requirements as given in SOI 68.2.
3.2 Do not exceed 5% nuclear power at any time while the test is in progress.
3.3 Abort the test if any of the following temperature limits are exceeded:
3.3.1 Core exit temperature of 610 F 3.3.2 AT as indicated by h- c of 65 F 3.3.3 avg temperature of 578 F 3.4 When equilibrium is established after the initial transient, avoid any sudden changes in Auxiliary Feedwater flow or in the Steam Generator water level.
3.5 Ensure seal flow to each' Reactor Coolant pump is maintained at or slightly above 6 gpm during the test.
3.6 AftertheReactorCoolantpumpsaretripped,tgenormalT and AT indication will become unreliable. AT and avg should E0 calcu-I lated by taking the difference and the average of the hot and cold Icg temperature indications respectively.
3.7 If the primary system pressure drops to a point where it is obvious that saturation pressure for the existing wide range hot leg or incore T/C temperatures will soon be reached, the pressurizer heaters will have to be energized or charging flow reestablished to increase system pressure.
3.8 NIS channels can be used to determine changes in core power level providing the RCS cold leg temperatures are maintained at approxi-mately the same value that existed before tripping the reactor coolant pumps.

detectors designed to isolate the steam supply to the turbine if t,he temperature reaches 125 F. If ambient temperature reaches 115 F, start the AC powered exhaust fan to help maintain tempera-ture.
3.10 Should a reactor trip occur during the conduct of this test, at least one reactor coolant pump (#2) should be started prior to closing the reactor trip breaker.

a) The output of the REF primary calorimetric will give a percent power output; this output must be input to the M/D Power-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.

-Rev. O APPENDIX C Part C: Using Thermocouples The incore thermocouples can le used as an indication of both core flow distribution and power shifts during natural circulation.
Prior to running a thermocouple map or trending the eight quadrant tilts (four center line and four diagonal tilts) the following should be verified:
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 Thermcouple Averaging Pro-gram at 1, 2, . . . X 8 seconds or 64 seconds for us.
The thermcouple programs breaks the core down into eight quadrants--
four centerline and four diagonal quadrants (see Figure C-1).
i Quadrants 1-4 can be directly correlated with the excore detectors
! but quadrants 5-8 cannot.
The quadrant tilts are indicative of power shifts and should be ,
trended at approximately a 2-minute frequency. The following q addressable values are the quadrant tilts:
Quadrant Addressable Value 1 U1159 2 Ull60 3 U1161 4 U1162 5 Ull51 6 Ull52 7 Ull53 8 U1154 A Short Form Map should be run periodically or upon request from the test engineer as an indication of core flow distribution. It should be put on the Utility Typewriter if possible. The P-250 Operator's-Console Reference Manual provides instructions for obtaining thermo-couple maps.
The trend output and Short Form Maps should be attached to this procedure at the end of the test.

, SQNP SPECIAL TEST 7 Page 1 of 11 Rev. O 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 wili initiate telling the operator that the condition exists and what the problem is. (2) a reactor trip will take place auto-matica11y. (3) a safety injection can be initiated manually from the switch in the control room if conditions warrant.

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 poiarity 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 48
