Cooldown Requirements Vs. Nat Circ Cooldown Rates

') g

1) FW requirements and the time to cooldown are controlled primarily by the characteristics of the ADVs and the cut-in.. conditions for  !

the DHR system. j

.t

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

l

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) 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 utilized. For smaller time delays smaller cooldown rates may be utilized.
