Project summary

The proposing institutions are as follows:
- The Keldysh Institute of Applied Mathematics (KIAM) of the Russia's Academy of Sciences.
- The Moscow Engineering and Physics Institute (MEPhI), which falls under the jurisdiction of the Committee on Higher Education of the Russian Federation.
- The Institute for Mathematical Modeling (IMM) of the Russia's Academy of Sciences.

All three of the partner institutions played an integral role in the nuclear-related military-industrial complex of the former Soviet Union. The KIAM and the IMM, which had been a part of the KIAM until approximately three years ago, worked in close cooperation with the large laboratories of the nuclear-related military-industrial complex such as the Russian Federal Nuclear Center at Sarov (Arzamas-16) and the Institute of Technical Physics in Kasli (Chelyabinsk-70). An integral part of the nuclear related complex was the higher-educational system that was established to produce skilled scientists and engineers for these laboratories. The focal point of this supporting educational system was the Moscow Engineering and Physics Institute (MEPhI).

In the project it is proposed to carry out basic studies unified by common theme of nuclear reactor safety and novel applications of transport theory.

The main goals of the project are:

- development of new numerical methods and corresponding codes for solving the neutral and charged particles transport equations, the coupled equations of spatial neutron kinetics and thermal hydraulics for regions of complicated structure taking into account real physical medium characteristics;

- development of tools for treatment and analysis of calculated results using sensitivity functions in order to obtain reliable estimations of the computational results accuracy and for application to optimization of designed nuclear devices;

- creation of standard tests for verification of approximate methods and codes, complicated numerical investigations on practically important problems of nuclear engineering, radiation shielding, optics of atmosphere and ocean.

Fulfillment of the planned investigations will result in the development of effective tools for mathematical simulation of different radiation fields in a wide range of scientific and technological problems.

The most important problems are:

- problems of safety of Nuclear Power Plants (NPP) and other objects of nuclear engineering (during startup, repair, stopping, as well as in emergency situations);

- problems of radiation shielding from neutral and charged particles of NPP, accelerators, plasma devices, space-crafts;

- problems of light radiation transport arising in climatology and monitoring of atmosphere and underlying surface.

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 the 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.

Most of project participants have been related to weapons of mass destruction. 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.

The project is a natural product of long collaboration between the Participating Institutions and a group of American scientists (mostly from the Texas A & M University) headed by professor P.Nelson. That is why these scientists are invited to take part in the project as consultants. Their participation will strengthen the project and give an additional impulse to the existing collaboration.


The International Science and Technology Center (ISTC) is an intergovernmental organization connecting scientists from Kazakhstan, Armenia, Tajikistan, Kyrgyzstan, and Georgia with their peers and research organizations in the EU, Japan, Republic of Korea, Norway and the United States.


ISTC facilitates international science projects and assists the global scientific and business community to source and engage with CIS and Georgian institutes that develop or possess an excellence of scientific know-how.
