Nuclear Fuel Cycles (class), Help

[mullig2]

I spent two days on this problem, but still couldn't figure it out, I would appreciate any help.  Thanks
Q1:
A nuclear power plant operated for a year with a 69% capacity factor.  What is the burnup of the fuel if the core contains 95 tons of uranium and has been designed to produce 1200 MW(e) with a 32% efficiency? What will be the average burnup, over the life of the plant, if one-third of the core is replaced every year? Assume a 30-yr life for the plant, constant capacity factor, and efficiency.

Q2:
Prove that if a utility pays 1 mill/kWh(e) for disposal of spent fuel, it is equivalent to $253/kgU. Assume a burnup of 33,000 MWD/MTU and an average thermal efficiency of 32%.

Q3:
A utility is given the choice of paying 1.2 mill/kWh(e) for a spent fuel disposal fee or $300/kgU at 35,000 MWD/MTU burnup and 32% efficiency. Which choice is more economical?

Q4:
Is it possible for the availability and capacity factors to be equal? Explain your answer.  Take into account the real operating conditions of a reactor.

If you spent two days on these problems, perhaps you need to select a new major.

I doubt anyone here is going to do your homework for you.
