A small laboratory reactor is designed to supply a steady thermal power of 1.0MW by utilising the fission of uranium-235. The average energy released in each fission is 200MeV. Assume that all the nuclear energy appears as useful heat.
(i) Calculate the number of fission events required per second to maintain the stated power output.
(ii) Determine the mass of uranium-235 that undergoes fission in one full day of continuous operation.
