Bubbling-vacuum installation for accident localization in standard NPP with two WWER-type reactors

Creators

Description

The present installation enchances the efficiency and safety in the elimination of the accident concequencies, as well as the efficiency of the dual-cycle NPP with 2x440 PWR. It is proposed to use only the volume of the usable part of the secondary circuit, e.g., the air chambers. The maximum accident superfluous pressure in the secondary side (linked air chambers) is reduced. The reduction of the superfluous pressure correspond to the reduced total amount of radioactive effluents and to reduction of radioactive burden in tne NPP environment. 2 cls., 2 figs
