SQNP SPECIAL TEST 6 Page 1 of 1 Rev. O TEST DESCRIPTION The reactor coolant pumps are tripped with the reactor suberitical and the primary system at hot standby. All steam generators are isolated on the secondary side.
Charging and letdown are increased to maximum capacity.
After 30 minutes charging and letdown is reduced to minimum. The cooldown rates are observed for these maximum and minimum conditions.

Date 2.4 Reactor coolant system pressure and level unde; automatic control at approximately 2235 psig and 25% level.
Date 2.5 Reactor coolant system temperature being controlled at approxi-mately 540 F by steam dump to the condenser under automatic pressure control.
(Steam generator pressure at approximately 948 psig).

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-matica11y.
(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.

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.

NOTE: The avg inputs to the high steam flou S.I and steam dump interlock are now blocked. The next steps will trip the steam flow inputs to the high steam flow Safety Injection signal so that an S.I. signal'will be initiated on low steam generator pressure alone (600 psig).
(This would result in a reactor l
trip, an S. I alarm, but no S. I. initiation.)
