In a reactor, an element X decays to a radioactive element Y, at a constant rate r atoms per second. Each decay reaction releases energy E_(1) . Half life of element Y is equal to T and decays to a stable element. During each decay of Y, energy E_(2) is released. If at t=0 , there was no atom of element Y and all the energy released is used in the reactor for generation of electrical power with efficiency eta , calculate electrical power generation in the reactor (i) at time t and (ii) in steady state.
