## Homework Statement

I am having issues with some problems relating to a plant theoretically shut down on natural circulation, and calculating the core ΔT and natural circulation flow rate.. Can anyone provide some equations or theory I could use to assist me? I'm not familiar with this material and have spent hours searching Google and cannot find much.

__Problem 1:__

Givens:

Initial Decay heat = 2.5% rated thermal power.

Initial Core ΔT = 14 deg F

Final Decay Heat = 1% rated thermal power

**Find:**Final Core ΔT.

__Problem 2:__

Givens:

Initial natural circulation flow rate = 3.5% full power flow rate.

Initial Core ΔT = 15 deg F

Final Core ΔT = 8 deg F

**Find:**Final natural circulation flow rate

## Homework Equations

I dont know any equations for this, I have searched for hours and cannot seem to find anything. If someone could reference me to any material they know of I can attempt a solution on my own first.
