AbstractAbstract
[en] The recombination coefficient is an important parameter for modelling hydrogen-metal interaction. It is responsible for hydrogen desorption from the surface of the metal and, therefore, significantly affects the hydrogen penetration into the metal, accumulation in and permeation through the metal. In the present work, the recombination coefficient of hydrogen (H) on tungsten (W) surface is examined. It is shown that the recombination coefficient of H on a clean W surface is extremely high which indicates the rapid desorption of the hydrogen molecule from the surface. Simulation using a high recombination coefficient well describes a wide range of experimental data of gas and ions interaction of hydrogen isotopes with tungsten. Proof of incorrectness of the Anderl's recombination coefficient is presented by comparing it with both theory and experiment.

AbstractAbstract
[en] Briefly, the invention comprises utilizing a shipping container with a storage rack for a quantity of filled pellets, the container also including sorbent material for gases which, when placed in a receptive state by exposure to vacuum and heat, will be in a condition to sorb gases that might be released from any fractured pellets during the course of transportation.

AbstractAbstract
[en] Production of multi-hydrogen (mH) isotopes in the spallation of 200A GeV sulphur projectile using nuclear emulsion is reported. Yield of mH isotopes is studied and compared with that of the lowest energy (3.7A GeV) data. The two-source emission picture is used to describe the transverse momentum (P_T ) distribution of mH isotopes (with and without the effect of "3"2S (γ,p) "3"1P channel). The Rayleigh type P_T -distribution seems to be in agreement with the corresponding experimental data. The contributions of low and high temperature emission sources show a dependence on the photonuclear processes. (author)

AbstractAbstract
[en] There is tested the behavior of three contact element types - bubble tray, sieve tray, ordered packing - to fit out the liquid hydrogen distillation column in the view of its isotopic separation. From the performance analysis there is chosen the ordered packing, which is then tested directly in an isotopic separation column, establishing its efficiency and pressure drop in a large operation range, presenting the maximal efficiency of 15 theoretical trays per meter at a load of 4.6 · 10-2 · kg1/2 · m-1/2 · s-1.(authors)

AbstractAbstract
[en] Results of an experimental study on a flowing bed process for continuous hydrogen isotope separation are presented. Separation performance was low with a 25% by weight palladium on alumina adsorbent, resulting in a high tritium inventory. In addition, significant breakdown of the solid adsorbent occurred as it recirculated through the process equipment and the product streams were contaminated by the adsorbent carrier gas. Due to these problems, this flowing bed process is predicted to be uneconomic for a full scale plant

AbstractAbstract
[en] The need for a reliable sensor with quick response for the measurement of hydrogen isotopes concentration in the liquid breeder is evident and its conceptual design is the aim of this work for testing the liquid type test blanket module in the International Thermonuclear Experimental Reactor (ITER), which have been designed and developed in KAERI. Among different possibilities, the choice of a sensor based on the principle of hydrogen isotopes permeation into a capsule of a suitable material seems to be, at least in principle, the simplest and the most reliable one
