Assuming that the change in temperature in the steam generator is linear with power (40% power equals a 40 degree change in temperature), what happens to the Average Coolant Temperature immediately after steam demand is reduced to 30%?
Does the ability of the moderator to thermalize neutrons improve or worsen for this change in Average Coolant Temperature? Why?
If, due to a changing fission rate, the hot leg temperature lowers to 390 degrees Fahrenheit, what is Average Coolant Temperature now?
