Title: Materials compatibility considerations for a fusion-fission hybrid reactor design

Abstract

The Tandem Mirror Hybrid Reactor is a fusion reactor concept that incorporates a fission-suppressed breeding blanket for the production of /sup 233/U to be used in conventional fission power reactors. The present paper reports on compatibility considerations related to the blanket design. These considerations include solid-solid interactions and liquid metal corrosion. Potential problems are discussed relative to the reference blanket operating temperature (490/sup 0/C) and the recycling time of breeding materials (<1 year).

  • The Tandem Mirror Hybrid Reactor is a fusion reactor concept that incorporates a fissionsuppressed breeding blanket for the production of /sup 233/U to be used in conventional fission power reactors. The present paper reports on compatibility considerations related to the blanket design. These considerations include solid-solid interactions and liquid metal corrosion. Potential problems are discussed relative to the reference blanket operating temperature (490/sup 0/C) and the recycling time of fissile materials (<1 year).
  • The paper presents the experiment tokamak reactor for developing of fusion-fission hybrid reactor technology and VNS. A fusion-fission hybrid reactor is a way to speed up the industry application of fusion energy, particularly for China where a nuclear fuel is not enough to supply a power demand. The development of fusion energy needs to build a VNS to study the fusion nuclear technology. The reactor main parameters are as following: R=4m, a=0.9m, k=2, plasma physics tests. For the fusion-fission hybrid reactor experiment the operation will be a steady state with low Q{sub p} (Q{sub p}=P{sub fus}/P{sub aux}), where P{sub n}=0.225more » MW/m{sup 2}, neutron flux N{sub 0}=0.236 x 10{sup 20} s{sup {minus}1}, the plutonium yield Gpu {>=}100 kg/year, the tritium breeding ratio T=1.02. As a VNS, the reactor will obtain P{sub n}=1.34 MW/m{sup 2} and N{sub 0}= 1.4 x 10{sup 20}s{sup {minus}1}, when the plasma operates in the case of advanced parameters. The paper describes the requirements of China fusion fission hybrid experiment reactor, the results of experiment tokamak reactor concept design and the reactor structure.« less
  • The status of the reference mirror hybrid reactor design being performed by LLL and General Atomic is summarized. The reactor parameters have been chosen to minimize the cost of producing fissile fuel for consumption in fission power reactors. The design draws on the experience developed at LLL in previous hybrid reactor conceptual designs and on GA expertise in gas-cooling technology and fission reactor mechanical design. As in the past, we have emphasized the use of existing technology where possible and a minimum extrapolation of technology otherwise. We consider our projections for the plasma physics parameters to be conservative, in thatmore » they are well-founded on the experiments in 2XIIB and the interpretation of these experiments.« less
