[en] Calculated simulation of testing regimes for the ITER reactor first wall model was carried out. Influence on these regimes for the first wall model sizes is studied by calculated way. The rates of heating and transmission regimes of heating are taking into account. The recommendation on selection model size and testing regimes were worked out in the results of the calculation

[en] The possibility of candidate materials test and thermonuclear reactor's elements of blanket is considered. The first wall' materials behaviour and breeding zone under thermal accident are examined. A using of different kinds of heating and its combinations in the IGR reactor could created wide-scale spectrum of TNR' materials tests under accident and transient conditions. 7 refs., 1 tab., 5 figs

[en] The report presents results of beryllium emissivity factor measurements within 700-1300 K temperature range. The tests were conducted at Institute of Atomic Energy of the National Nuclear Center of the Republic of Kazakhstan to receive experimental data for verification of calculation programs describing an accident involving water coolant discharge into ITER reactor vacuum cavity.

[en] Purpose of the work is obtaining of precision description of heat propagation due to reaction evolving in the and it interaction on the ITER structures and atmosphere within reactor vessel and prediction of hydrogen release in the case of the beryllium with vapour reaction. For the experiments conducting the unit for interaction of vapour and metal is implemented. The unit consists of vacuum chamber in which are arrangement ed the following systems: System for vacuuming; system for preparation and water vapour feed back into the chamber; System for measurement and registration of parameters. Quantity of hydrogen have being measured by volume method. Hydrogen substituted water out of gas bell and its volume is determined by pressure under the bell with taking into account the water vapour partial pressure and hydrogen solubility in the water

[en] This report includes results of measuring beryllium emissivity factor in wide temperature range. Experiments were made at IAE NNC RK in order to obtain experimental data meant for verification of calculation codes describing accident situation involving water coolant release into vacuum cavity of ITER reactor. The outcomes, obtained from the experiments conducted under different conditions, have various quantitative values. But, depending on the basic determinative values, they obey to common laws. When the partial pressure of water steam in the vacuum chamber increases, beryllium samples are oxidized more intensively. However, a tendency to emissivity factor variations remains the same, not depending on a water steam concentration value
