In the Dual Fluid Reactor (DFR) plants, there are two separated loops in which liquid metals, Uranium-Chromium eutectic as fuel and lead as a coolant will flow. Due to the high operating temperature of DFR, special contact-free pumps have to be applied. The best solution seems to be a magnetohydrodynamic pumping system which can utilize magnetic and electric fields acting on the metallic flow.

The first-of-a-kind commercial electricity and hydrogen cogeneration system are being designed by the Japan Atomic Energy Agency (JAEA) to establish the industrial application of high-temperature gas-cooled reactors (HTGR). The High Temperature Engineering Test Reactor (HTTR) is expected to be coupled with a test cogeneration plant in order to prove safety features and justify further HTGR technology development. The National Centre for Nuclear Research (NCBJ) initiated activities on reliability analysis of such a combined nuclear/non-nuclear facility.

The Technical Working Group on Gas Cooled Reactors is a group of experts nominated by their governments and appointed by the International Atomic Energy Agency (IAEA) Secretariat to provide advice and support programme implementation in the area of gas cooled reactor technology development. The purpose of the TWG meetings is to identify subjects of common interest for future collaboration through information exchange and cooperative research.

Rutherford backscattering spectrometry is used to determine the structure and composition of materials by measuring the backscattering of a beam of high energy ions (typically protons or alpha particles) impinging on a sample. Computer modeling of RBS is used for analysis of modeled structures created by molecular dynamics method.
