Passive Catalytic Hydrogen Recombiners for Nuclear force out Stations V. D. Keller All-Russia Thermal Engineering instal (VTI), ul. Avtozavodskaya 14/23, Moscow, 115280 Russia gypA description is given of the design and main skillful characteristics of peaceful catalytic total heat recombiners that ar intended for decrease the ducking of heat content in hermetic premises of thermonuclear originator stations during accidents. Speci?c features of the catalyst apply in the devices are considered. DOI: 10.1134/S0040601507030111 A considerable amount of hydrogen may enter into the hermetic volume of the reactor structure at nuclear effect stations (NPSs) equipped with VVER reactors if design-based and beyond-design-based accidents turn over there, which presents a hazard for the inte grity 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 positively charged by the safety regulations for NPSs as mandatory for their localizing safety systems. In the wee 1990s, some Russian research and design organizations, amon g them the Atomenergoproekt Institute, the R! ussian seek Centre Kurchatov Institute of Atomic Energy, the OAO All-Russia Thermal Engineering Institute (VTI), and the Energy Physics Institute, began to develop hydrogen monitor 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 fully essay, articulate it on our website: BestEssayCheap.com
