CAN ONE OF YOU HOMOS HELP ME WITH THIS PROBLEM?
So with a homogenous reactor with GP1 as the scram group, GP 2 and GP 3 are the controlling group. GP 1 has a group rod worth of about 100x10-4 units of reactivity/inch, GP2/3 have group rod worth of 200 x 10-4 units of reactivity/inch,
Average temperature coefficient of reacitivy is roughly -3 units of reactivity/farenheit.
Rod 2-3 drops from critical rod height, and feed flow stops, and temperature rises 15 degrees. Whats the overall reactivy of the core?
