Compressed Air Vacuum System for Localization of Accidents in Nuclear Reactors.

摘要

The invention, entitled ''Compressed Air Vacuum System for Localization of Accidents in Nuclear Reactors'' concerns a limited but important area of nuclear energy that is currently being developed and implemented in the COMECON member states in the form of specific government programs. The invention solves the problem of increasing the operating safety of the strategic safety system in standardized nuclear power plants by means of two loops of Soviet design and by homogenization of a corresponding system of technical elements, as well as by the maximum possible improvement in the reparability of the most sensitive elements of the system. The nature of the invention lies in the fact that water seals are used instead of the large-sized double return valves and that the entire valve system of the Barbotage condenser, which requires frequent inspection and maintenance, is located in the second chamber, which has better access during normal operation. From the standpoint of the technological, hydraulic and thermal engineering parameters of the system, the modification described is characterized only by positive effects. The invention is an asymmetrical, one-sided, i.e., reverse impermeable high-pressure water seal, which consists of a pipeline, the water seal, and a water seal tank. It is characterized by complete leaktightness and complete operating safety, through which is guaranteed the necessary hydraulic-thermal uniformity of operation of the multichannel, parallel-connected system mentioned above. 1 fig.
