Project summary

The main goal of the project is to prepare scientific monograph “Coupled pulsed reactor systems” for publication in English. The monograph will be devoted to theoretical problems and methods for computer simulation of non-stationary processes in multizone multiplicative systems of nontraditional type, such as sectioned reactors, coupled pulsed nuclear systems, etc. Coupled reactor systems are investigated by many research teams, both in Russia and abroad. Primarily, the interest to this subject is due to the new, unique experimental prospects opened thereby for physicists. It should be emphasized that the systems mentioned above might be promising for the development of non-traditional nuclear facilities intended for special applications: subcritical blankets for hybrid fission-fusion and electronuclear units, including accelerator-driven systems for energy generation and burning/transmutation of radioactive wastes and weapons-grade plutonium (WGPu), super-powerful nuclear pumped lasers, energy reactors with extensive reproduction of nuclear fuel, etc. Such systems were shown to be typified by a set of qualities that cannot be achieved for traditional reactors. All these circumstances necessitated the development of a special theory for coupled systems and new approaches for numerical simulation of neutronics and dynamic processes.

The monograph will be devoted to the description of methods of numerical simulation for the coupled system dynamics, first of all for the pulsed type systems. A special variant of a coupled system containing one (or more) deeply subcritical components will be considered particularly. We suppose to discuss the problems of the analysis of non-stationary neutron transport processes in the multizone multiplicative installations, methods for the modeling of dynamics, and describe effective approaches for numerical simulation. Results of verification for mathematical models and their realization as computer codes using experimental data obtained on coupled nuclear reactors of various types and applications will be summarized and reviewed in detail. We also suppose to analyze some concepts of prospective nuclear energy systems based on the principle of neutron coupling between components of the system. It should be noted that to date, no comprehensive scientific publications describing methods for solving such tasks exist in English or in Russian.

Primarily, the monograph will be oriented to scientists and specialists in the area of nuclear physics and reactor engineering, interested in mathematical (computer) modelling of fast processes in coupled nuclear reactors. The project participants and co-authors have gained a wealth of experience with the development of approaches for theoretical and experimental analysis of coupled reactor systems and in the area of information technologies. Results of finalized research programs have been published in various Russian and foreign scientific journals and proceedings and presented at international conferences.

The data and methods to be described in the monograph might find extensive practical uses in the solution of various problems related to the reactor physics and neutronics, such as:


- Substantiation and assessment of criticality safety and designing data on the operating nuclear facilities and those under development to special applications: subcritical blankets for hybrid fission-fusion and electronuclear units, including accelerator-driven systems for energy generation and burning/transmutation of radioactive wastes and WGPu, super-powerful nuclear pumped lasers, energy reactors with extensive reproduction of nuclear fuel, etc.;

- Development of new methods for diagnostics and measurement of characteristics of nuclear systems operating in steady-state and non-steady state modes;

- Theoretical and experimental optimization of neutronics parameters of multiplicative systems for upgrading their designing data and nuclear safety level, expand spectra of experimental options, etc.;

- Mathematical simulation of fast processes in multiplicative nuclear systems of complex geometry and isotope composition, development of the on-line computer simulators of coupled reactors, etc.

The project fully corresponds to the ISTC goals in terms of supporting fundamental and applied research intended for the investigation of physical processes in non-traditional multiplicative systems and substantiation of their nuclear and ecological safety.

In the framework of the project, close cooperation with foreign collaborators is planned for information exchanges on the work to be done and their prospects, evaluation of outlooks, etc., including management of the future monograph publication abroad.
