Processing of the JEFF Jerzy Cetnar, General solution of Bateman equations for nuclear transmutations. It has been demonstrated that LFR meets the requirements of the closed nuclear fuel cycle, where plutonium and minor actinides MA are recycled for reuse, thereby producing no MA waste.
The paper shows methodology applied to the LFR equilibrium fuel cycle assessment, which was developed for the Monte Transmutatikns continuous energy burnup MCB code, equipped with enhanced modules for material processing and fuel handling. As was written, this model can be also used in nuclear depletion codes to solve nuclear transmutation and decay problems as well.

The Bateman equations for radioactive decay case of n — nuclide series in linear chain describing nuclide concentrations are as follows:. The concept of closed nuclear fuel cycle seems to be the most promising options for the efficient usage of the nuclear energy resources. A new paradigm for core design aimed at the sustainability of nuclear energy: In physics, the Bateman equations are a set of first-order differential equations, which describe the time evolution of nuclide concentrations undergoing serial or linear decay chain.
Actinide and Fission Product Partitioning and Transmutation. The model was formulated by Ernest Rutherford in and the analytical solution for the case of radioactive decay in a linear chain was provided by Harry Bateman in Physics of Nuclear Kinetics.
Lamarsh, Introduction to Nuclear Reactor Theory, 2nd ed. This is the concept of a fuel cycle which asymptotically tends to the adiabatic equilibrium, where the concentrations of plutonium and MA at the beginning of the cycle are restored in the subsequent cycle in the combined process of fuel transmutation and cooling, removal of fission products FPsand admixture of depleted uranium.
In this transmutatjons, generation of nuclear waste containing radioactive plutonium and MA can be eliminated.
ORIGEN uses a matrix exponential method to solve a large system of coupled, linear, first-order ordinary differential equations similar to the Bateman equations with constant coefficients.
Table of Isotopes 8E. Nuclear and Particle Physics. For example, ORIGEN is a computer code system for calculating the buildup, decay, fog processing of radioactive materials. These equations are usually used for the exact evolution of isotopic changes in the nuclear fuel during fuel depletion.
The numerical analysis of the reactor core concerns multiple recycling and recovery of long-lived nuclides and their influence on safety parameters. However, it can be implemented only in fast breeder reactors of the IVth generation, which are characterized by the fast neutron spectrum. Annals of Nuclear Energy 33 The paper also presents a general concept of the novel IVth generation breeder reactor with equilibrium fuel and its future role in the management of MA.
