Project summary

The Project is aimed at experimental determining and computer-aided simulating the independent and cumulative yields of residual product nuclei in thin targets made of the target materials and structure materials of the transmutation plants driven by a high-current high-energy proton accelerator. The Project extends the research work carried out under Project #17 ISTC "Feasibility Study of Technologies for Accelerator Based Conversion of Military Plutonium and Long-Lived Radioactive Waste" pertaining to the basic researches with measuring cross sections and perfecting nuclear models in the intermediate energy range. The Project will be realized using the methods, equipment, and computer hardware and software designed and purchased in the course of implementation of Project #17.

Like the projects of some overseas Laboratories (ABC, PHOENIX, SINQ, and others), Project #17 treated several conceptual design versions of electronuclear plants. 'Heavy' nonfissionable materials (such as Pb, Pb-Bi eutectics, W, Hg), as well as fissionable materials (such as Th and U), are proposed to use as target materials of the plants. Fission products, such as 99Tc, 90Sr and others, are proposed in some projects to admix to the target materials. As shown by A.J.Koning in his review work Review of high energy data and model codes for accelerator-based transmutation (ECN-C-93-005), nuclear data on the yields of residual nuclei for the given materials at energies above 20 MeV are very scanty at the International NSR and EXFOR Libraries (the vertical and horizontal lines in the Figure below, respectively).

From the Figure it is seen also that the nuclear data are insufficient for such structural materials as Co and Cu, and are actually absent for such target materials as the W isotopes, 99Tc, Th, and U.


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.
