Project summary

The aim of the project is the development and creation of radioactive 10Ве and tritium targets for fundamental nuclear physics research experimental search and investigation of light neutron-rich nuclei near the drip-line.

Nowadays experimental research on synthesis and study of light neutron-rich nuclei is performed in many laboratories of the world. The experiments are carried out with the help of various types of nuclear reactions on heavy ions beams, and also on pion beams in double charge exchange and negative pion absorption reactions.

One of the main conditions for the progress in production of the most neutron-rich nuclei is the realization of the maximal neutron enrichment in the initial stage also. The 10Ве (N/Z = 1.5) and tritium (N/Z = 2.0) targets have the greatest N/Z ratio and will allow to execute effective search for and spectroscopy of such exotic nuclear systems as multi-neutrons, super-heavy isotopes of hydrogen, helium and lithium.

Progress in the target characteristics, which is planned to create within the framework of the present project, is based on use of potentialities of high power fast reactors, and also developments of safety operation systems for nuclear installations.

10Ве in an amount of 10—100 mg is planned to extract from the spent rods of control and safety systems of the BN-600 reactor, where this isotope is produced in the neutron charge exchange reaction: 10В(n,p)10Ве. Such amount of 10Ве will be enough for manufacturing targets 260 mg/сm2 thick, which is more than one order of magnitude above the existing today.

For the creation of tritium targets the IPPE experts experience of work with hydrogen-containing materials, including hydrides of metals, will be used. This experience was received during designing and operation of moderators and shielding facility for small nuclear reactors.

The execution of this project will orient the scientists, engineers and technicians, working earlier on tasks of weapons themes, towards the new purposes, directed on peaceful use their high qualification for creation of technologies and devices for use in fundamental research and the solution of the ecological problems.

The technological developments of this project should find employment for the solution of the complex problem of radioactive wastes reprocessing.

The test pieces of the targets will be used in fundamental research by the scientists from MEPhI and IGNP Russian Scientific Center “Kurchatov Institute”, including collaborations with leading scientific centers of Japan, Europe and USA.


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.
