Fast-burst reactors are designed to provide intense, short-duration pulses of neutrons. The fission reaction also produces extreme time-dependent heating of the nuclear fuel. An existing transient-dynamic finite element code was modified specifically to compute the time-dependent stresses and displacements due to thermal shock loads of reactors. Thermomechanical analysis was then applied to determine structural feasibility of various concepts for an EDNA-type reactor and to optimize the mechanical design of the new SPR III-M reactor.

Coupling neutronics to thermomechanics is important for the analysis of fast burst reactors, because the criticality and safety study of fast burst reactors heavily depends on the thermomechanical behavior of fuel materials. For instance, the shut down mechanism or the transition between super and sub-critical states are driven by the fuel material expansion or contraction. The material expansion or contraction is due to temperature gradient which results from fission power. In this paper, we introduce a numerical model for coupling of neutron diffusion and thermomechanics in fast burst reactors. We also provide some analysis of the coupled system. We studied material behaviors corresponding to different levels of power pulses.

Fast Pulsed and Burst Reactors: A Comprehensive Account of the Physics of both Single Burst and Repetitively Pulsed Reactors discusses the physical principles involved in the operation of fast burst and periodic pulsed reactors. The text first covers the concerns in fast burst reactors, such as the kinetics and the effects of thermal shock. Next, the book deals with periodic burst reactions, which include the neutronics theory, reactivity modulation, and fluctuations. The text also talks about the principles and problems of control and safety of periodic pulsed reactors. The book will be of great use to individuals involved in the operation of nuclear power plant, such as nuclear engineers. The text will also benefit scientists involved in nuclear research.
