Mass of the fuel consumed at the reactor each year.

Relevant Equations

Hi fellows. I am dealing with the following question and any help to solve it will be a huge favor.
Let us consider a nuclear power plant which delivers 100 MWe. The plant is based on a Rankine cycle, where the steam exiting the reactor is at 350 C and water exits the condenser at 20 C. The efficiency of the cycle is 90% of its maximum theoretical efficiency and the efficiency of the generator is 98%.
What is the mass of the fuel consumed at the reactor each year if the reactor is enriched to 3% U-235 (i.e. 3% of the fuel is U-235)? Assume the energy generation is due to solely U-235 fission. Take into account that 15% of collisions with neutrons do not yield fission.

Actually, this is not a homework, this is a question asked to me. I am a physicist withouth enough experience in this topic. This is why I posted here. Since I never used the homework topic in here, please forgive me for any unconvinience. It is OK if the administratives would like to delete the post. Thanks for the reply and your time.

Best.
