Avtozavodskaya 14/23, Moscow, 115280 Russia come upA description is given of the design and main practiced characteristics of peaceful catalytic total heat recombiners that ar intended for trim back the ducking of enthalpy in hermetic premises of atomic originator stations during accidents. Speci?c features of the catalyst utilize in the devices are considered. DOI: 10.1134/S0040601507030111 A considerable amount of hydrogen may enter into the hermetic volume of the reactor create at nuclear role stations (NPSs) equipped with VVER reactors if design-based and beyond-design-based accidents bechance there, which presents a hazard for the integrity of the hermetic containment. An emergency hydrogen remotion system employing the catalytic hydrogen recombiners is currently used to expire this phenomenon.

The operating principle of these recombiners is based on recombining hydrogen with oxygen on a catalyst without an additional power contribute and without control signals for switching the system into operation. Thus, these devices work in agreement with a passive operation principle, the use of which is official by the safety regulations for NPSs as mandatory for their localizing safety systems. In the wee 1990s, some Russian research and design organizations, among them t he Atomenergoproekt Institute, the Russian ! seek Centre Kurchatov Institute of Atomic Energy, the OAO All-Russia Thermal Engineering Institute (VTI), and the Energy Physics Institute, began to develop hydrogen supervise and afterburning systems. By this time, VTI specialists had completed the development a passive catalytic hydrogen recombiner (burner) (the PG-317 model) intended for...If you want to get a mount essay, articulate it on our website: OrderCustomPaper.com
