In a nuclear reactor an element X decays...

In a nuclear reactor an element `X` decays to a radio active element `Y` at a constant rate `10^(15)` atoms per sec. Each decay release `100 MeV` energy. Half life of `Y` equals `T` and decays to a stable product `Z`. Each decay of `Y` releases `50 MeV`. All energy released inside the reactor is used to produce electricity at an efficiency of `25%`. Calculate the electrical power in `kw` generated in the reactor in steady state.
