Hefei experimental hybrid fusion-fission reactor conceptual design

Abstract

A new concept of hybrid reactor is introduced. It uses JET-like(Joint European Tokamak) device worked at sub-breakeven conditions, as a source of high energy neutrons to induce a blanket fission of depleted uranium. The solid breeding material and helium cooling technique are also used. It can produce 100 kg of {sup 239}Pu per year by partial fission suppressed. The energy self-sustained of the fusion core is not necessary. Plasma temperature is maintained by external 20 MW ICRF (ion cyclotron resonance frequency) and 10 MW ECRF (electron cyclotron resonance frequency) heating. A steady state plasma current at 1.5 Ma is driven by 10 MW LHCD (lower hybrid current driven). Plasma density will be kept by pellet injection. ICRF can produce a high energy tail in ion distribution function and lead to significant enhancement of D-T reaction rate by 2 {approx} 5 times so that the neutron source strength reaches to the level of 1 x 10{sup 19} n/s. This system is a passive system. It`s power density is 10 W/cm{sup 3} and the wall loading is 0.6 W/cm{sup 2} that is the lower limitation of fusion and fission technology. From the calculation of neutrons it could always be in sub-critical and  More>>

According to the conceptual design the application of this type hybrid reactor earlier is feasible.}
