Project summary

This project is proposed by four leading scientific institutions of Russia:
- Keldysh Institute of Applied Mathematics (KIAM);
- Russia's Federal Nuclear Center Arzamas-16;
- Institute of Mathematics and Mechanics;
- Russia's Federal Nuclear Center Chelyabinsk-70.

These Institutions are directly related to the well known achievements of our State in space exploration, in the rocket industry, in developing nuclear weapons, in pure and applied mathematics, and so on.

This Project involves theoretical investigations and creation of software adapted to multi processor computers including massively parallel systems with a view to simulating standard and emergency processes in nuclear power plants of various kinds and purposes. The mathematical foundation of the dynamic processes occurring in nuclear reactors is equations of neutron kinetics and reactor dynamics coupled with equations of thermal hydraulics, gaseous dynamics, thermal conductivity, strength properties, phase transitions and so on.

Computationally this Project requires very high characteristics of computing hardware. At the time being only multi processor computers or perhaps even only massively parallel computer systems can offer a workable line of attack on the problem of solving systems of multi-dimensional non-linear time-dependent equations which may arise. Because of this, one the basic feature of the project is design and adaptation of methods for solving equation of mathematical physics on parallel and massively parallel computers. This would allow to solve many problems, which have defied traditional computers, and to increase significance of numerical modeling in project investigations. At present this direction of investigation is rapidly gathering momentum. For scientists from the CIS it would be very useful to get into the act in this priority area. Results, techniques, methods, and any other achievements obtained within the framework of this Project will be reported in the open literature, presented at conferences, symposiums, seminars, and so on. This side of integration process of CIS's scientists into the world scientific community is naturally complemented by the other one: implementation of the project will require careful and comprehensive study of the world science achievements in these particular fields of knowledge.

There will be utilized a good portion of already finished work and results obtained by the researchers of the proposing institutions. These results exist in form of physical and mathematical models of basic processes occurring in nuclear reactors, methods of solving complicated equations, experience of accumulating and creating data banks of neutron and thermal physical properties, as well as experience of developing sizable program projects.

This Project will permit to redirect talents of weapon scientists to peaceful activities. Obtained results and software will be available for international scientific community and hopefully will be widely taken up in science, education, and industry. All this corresponds to the ISTC's objectives.
