Project summary

Starting from the middle of the 80-s there have been a lot of activity worldwide, Russia included, in developing of emerging nuclear facilities for transmutation of long-lived nuclear wastes. Accelerator driven transmuters received the most attention. Being subcritical, these facilities need in intensive high energy proton accelerator that drives the neutron source in the center of the reactor core. The main feature attributed to accelerator-driven transmuters is an essential broadening in the nucleon energy (up to 1 GeV) compared to traditional fission reactor. Concerning their fuel composition, it is worth to emphasize that subcritical mode of operation gives an opportunity to burn out large amounts of minor actinides. It is matter of fact that the field of accelerator-driven transmutation suffers from the lack of nuclear data for both minor actinides of fuel compositions and structural materials in the energy region above the traditional reactor energies (0.01 – 1 GeV).

A number of projects devoted to the lack data obtaining have been carried out in ISTC lately. But so far there is no analysis of connection of the projects results with the special requirements of transmuters designing. The project suggested assumes that detailed analysis of the projects carried out in ISTC will be performed in order to find out the contribution of the projects in question to the accuracy advancement of transmuters parameters calculation. A list of new parameters that still require more accurate definition and corresponding investigations is assumed to indicate. According to the analysis results the priorities of subsequent experimental and theoretical investigations for different types of transmuters will be found out.

The participants of the project are: INPE, ITEP, Khlopin Radium Institute, RENC-VNIIEF, IPPE, RRC Kurchatov Institute, RDIPE.


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.
