.( )L Cooldown Requirements Vs. Nat Circ Cooldown Rates -

J ..

1). FW requirements and the' time to cooldown are controlled primarily s

by the characteristics of the ADVs and the cut in conditions for .

the DHR system.

I.

2) The time to' cooldown from Rx trip is about 45 hrs. .

3) .The'FW requirement to cooldown is about 350,000 gal.

4)' The minimum cooldown rate consistent with the above minimum time and FW requirements.is about 8.5'F/hr.

5) Cooldown rates in excess of 8.5*F/hr do not' decrease the FW or time-requirements for cooldown.

6)1 Cooldown rates less than'8.5'F/hr increase both the FW and the time requirements for cooldown.

7) A time delay of 28 hours3.240741e-4 days <br />0.00778 hours <br />4.62963e-5 weeks <br />1.0654e-5 months <br /> from Rx trip will not significantly affect FW or time requirements if a cooldown ' rate of 50*F/hr is then i utilized. For smaller time delays smaller cooldown rates may, be utilized.
