A new surrogate method for the neutron kinetics calculation of nuclear reactor core transients
Reactor core transient calculation is very important for the reactor safety analysis, in which the kernel is neutron kinetics calculation by simulating the variation of neutron density or thermal power over time.

On a significant slowing-down of the kinetics of fast transient processes in a fast reactor [PDF]
The kinetics of nuclear reactors is determined by the average neutron lifetime. When the inserted reactivity is more than the effective delayed neutron fraction, the reactor kinetics becomes very rapid.

On the concept of “effective delayed neutron fraction” [PDF]
The article considers methodological issues related to the conceptual and terminological apparatus of the dynamics of nuclear reactors. Based on an elementary analysis of the standard point reactor kinetics equations, the author shows that it is ...

Assessment of the neutron flux stability in a high power BN-type reactor in terms of modal spatial kinetics [PDF]
The article discusses the neutron flux stability in the core of a high-power sodium-cooled fast reactor (of the BN-type) without feedbacks. The importance of this problem for high-power BN-type reactors is associated with the specific features of the ...

Kinetics equations for neutron distributions [PDF]
Abstract Kinetic equations for neutrons and some of the other kinds of particles important to neutron balance in reactors and reactor-like systems are derived from a quantum Liouville equation. In particular, equations for some of the relevant singlet and doublet densities in phase space are deduced for the purpose of studying neutron density ...
