Next-Step Option Physics (Grant ER54350)

Abstract

For more than a decade we have been involved in physics and design analysis of possible nextstep tokamak options, including first ITER, later FIRE and most recently a tokamak neutron source for a near-term transmutation reactor for burning the transuranics in spent nuclear fuel. We have also recently supported the National Transport Code Coordination activity under this grant. In recent years, much of the effort has been devoted to defining the physics and performance characteristics required of a tokamak fusion neutron source that could drive a sub-critical reactor for the transmutation of the transuranics in spent nuclear fuel. This document provides a final report for the activity in each of these areas for the last grant period.
