I am trying to build a model of CANDU reactor core using a software called DYMOLA.For this purpose,I am trying to figure out a mathematical relation between coolant temperature and Power developed in a reactor.I have the following questions:(adsbygoogle = window.adsbygoogle || []).push({});

1.What is the effect of increasing the neutron flux (hence,increasing the power developed in the core) on the coolant exit temperature.Is there a mathematical relation that relates the temperature of coolant coming out of the reactor to the neutron flux.

2.I read that in a CANDU reactor a decrease in coolant temperature increases the reactivity.

But,consider the following scenario:

Coolant temperature decreases---->>Reactivity increases---->>Power developed in the reactor increases---->>resulting in an increase in coolant temperature---->>which decreases the reactivity!!

When does the cycle stop??

Hope you understood my question
