Fuel depletion is usually modelled mathematically as a set of differential equations known as evolution equations. Annals of Nuclear Energy 33 If you continue to use this site we will assume that you agree with it. 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.

The solution of the extended equilibrium state. Los Alamos National Laboratory. This model can be also used in nuclear depletion codes to solve nuclear transmutation and decay problems. Abstract PDF References Article Recommendations Abstract The concept of closed nuclear fuel cycle seems to be the most promising options for the efficient usage of the nuclear energy resources. These equations are usually used for the exact evolution of isotopic changes in the nuclear fuel during fuel depletion.

In this way, generation of nuclear waste containing radioactive plutonium and MA can nuclrar eliminated. It has been demonstrated that LFR meets the requirements of the closed nuclear fuel bwteman, where plutonium and minor actinides MA are recycled for reuse, thereby producing no MA waste.

A new paradigm for core design aimed at the sustainability of nuclear energy: The numerical analysis of the reactor core concerns multiple recycling and recovery of long-lived nuclides and their influence on safety parameters.

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. Modeling minor actinide multiple recycling in a lead-cooled fast reactor to demonstrate a fuel cycle without long-lived nuclear waste.

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 Processing of the JEFF However, it can be implemented only in fast breeder reactors of the IVth generation, which are characterized by the fast neutron spectrum.

The paper shows methodology applied to the LFR equilibrium fuel cycle assessment, which was developed for the Monte Carlo continuous energy burnup MCB code, equipped with enhanced modules for material processing and fuel handling. For example, ORIGEN is a computer code system for calculating the buildup, decay, and processing of radioactive materials.

Nuclear and Reactor Physics: In foor of transmutation the decay constants that govern Bateman equations for a decay case are substituted by transmutation constants.
