Constricted liquid metal curtain for inertial confinement fusion reactors.

First Wall Evaporation in Inertial Confinement Utilizing Gas Protection Fusion Reactors

The evaporation of inertial confinement fusion first wall materials from unattenuated pellet X-rays and from radiation emitted by a cavit.y buffer qas is examined. The low vapor pressure and low X-ray attenuation coefficient of carbon give it a lower erosion rate than stainless steel, despite the larger thermal conductivity of Type 316 stainless steel. For the argon buffer gas containing 0.2% N...

Design of an Actively Cooled Grid System to Improve Efficiency in Inertial Electrostatic Confinement Fusion Reactors

The Interaction of Helium and Displacement Damage in Inertial Confinement Fusion Reactors

Helium is thermodynamically insoluble in metals and tends to form cavities if the conditions are appropriate for its migration. The processes of helium migration and interaction with point defects are strongly influenced by the level and the mode of displacement damage production. In this paper, we present an application of the rate theory for helium cavity formation in Inertial Confinement Fus...

Production and Behavior of Point Defects in Pulsed Inertial Confinement Fusion Reactors

A time-dependent neutronics analysis for the HIBALL reactor is presented. The helium to dpa ratio in the ferritic steel structure is found to be sensitive to neutron spectrum softening. The microstructure calculations show that helium diffusivity is a sensitive function of vacancy accumulation from one pulse to the next. A strong coupling exists between the three components of damage: helium, v...

Liquid Metal Fast Breeder Reactors

A study of future energy requirements and of the potential of various energy sources (coal, oil, gas, nuclear power, hydropower and solar energy) indicates that the contribution to be made by nuclear fission, now competitive with conventional energy sources, will grow steadily over the next few decades. Whereas the amount of fuel which has to be fabricated each year for the operation of a nucle...
