Calculate the reactor period for 235U fuel for a reactor of -200 pcm and a rate of reactivity change of 2 pcm/s. The prompt generation lifetime is 2.1×10-4 sec and βeff=.0065 and λeff=.1/sec. What is the ratio of the delayed term to the prompt term?

Calculate the stable reactor period for a 235U fueled reactor with a reactivity of .001. βeff=.0065 and λeff=.08/sec

Calculate the reactor start-up rate when the reactor period is two minutes. Include the units.

The power level of a reactor is 10,000 W. The doubling time is 1.8 minutes. What is the reactor power 1 minute later? What is the reactor power 5 minutes later? What is the reactor power 25 minutes later? When is the reactor power 3000MWth?
