Borehole Siting Technique for Geological Repositories of Radioactive Waste

 

 

 

 

The purpose of siting repositories is to reveal those most promising for the development of deep geological repository (DGR) for radioactive wastes. The technique of siting borehole DGRs is described as follows.

 

Neutron Tubes NTG-2, NTG-3

The neutron tube NTG-2 is comprised of a cermet (glass- metal) body housing a Penning-type ion source with incandescent or cold cathode, a system of forming and accelerating electrodes, and a neutron-generating target. The distance between the active target surface and the tube face is 25 mm. In the glass-metal version this distance is 1 mm. The neutron tube NTG-3 is made of cermet (glass-metal) body housing an orbitron ion source.

Semiconductor Detectors for Nuclear Radiation Spectrometry

Semiconductor detectors are among the most important devices employed for the spectral analysis of nuclear radiation, although the type of semiconductor detector to be used depends on the specific problem to be resolved.

Tritium-containing Targets for Neutron Generators

These targets are intended for generating neutron fluxes with energies of up to 14 MeV for the d (T, n) reaction and 25 MeV for the d (D, n) reaction.

Neutron Source FOF Neutron Capture Therapy of Cancer Tissues at Kyiv Research Reactor (KRR)

The large thermal neutron capture cross section of 5B10 greatly increases the probability of the resulting 5B11 nucleus to split into He and Li.

Neutron Filtered Beam Technique at the Kyiv Research Reactor (KRR)

The neutron filter technique is characterized by the transmission of neutron beams emanating from nuclear research reactors through relatively thick (up to 2–2.5 m) layers of materials with deep interference minimums in the total neutron cross sections. As a result of passing through these interference minimums, narrow energy range "filtered" neutrons emerge as quasi-monochromatic beams.

Tritium Static Eliminators (TSET)

 

 

 

 

 

Tritium sources for generating soft beta-radiation (BITr-M) are at the heart of the static eliminators developed by physicists at the Kyiv Institute for Nuclear Research.

Photonuclear Technology for Isotope Production

 

 

The novel soft technology for production of isotope Mo-99/Tc-99m, Cu-67, Sc-47, Co-57, W-181, Pt-195m and oth. with the use of high-energy bremsstrahlung of the electron accelerator has been developed.
