Abstract: A proposal of 200MW Inertial Confinement Fusion Fission Hybrid reactor which does not produce plutonium is presented on the basis of one dimensional discrete ordinate transport calculation and burmup calculation by using code BISON 1.5^[4].The time dependent results of energy deposit,²³⁸U(n,γ),239Pu(n,α),⁶Li(n,α) reac-tion rates and K_eff are given.Such a novel reactor proposed here not only could maintain high output power but also could keep critical safety.

Key words: Inertial confinement, Fusion fission Hybrid reactor, critical safety
