Avtozavodskaya 14/23, Moscow, 115280 Russia Abstractâ€"A description is given of the design and main technical characteristics of peaceful catalytic hydrogen recombiners that ar intended for reducing the ducking of hydrogen in hermetic premises of nuclear originator stations during accidents. Speci?c features of the catalyst used in the devices are considered. DOI: 10.1134/S0040601507030111
A considerable amount of hydrogen may enter into the hermetic volume of the reactor building at nuclear power stations (NPSs) equipped with VVER reactors if design-based and beyond-design-based accidents occur 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 prescribed 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 the 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 monitoring 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 full essay, articulate it on our website: Orderessay
