Problems solved by technology

[0003] Due to limited space, nuclear-powered ships usually do not fully consider the control method of entering and exiting the control area, and do not set up special facilities for the control of entering and exiting the control area. However, as people have higher and higher requirements for radioactive pollution protection, in order to To effectively prevent the spread of radioactive pollution, nuclear-powered ships also need a complete control method for entering and exiting the control area to control the entry and exit of personnel and objects
[0004] Although land-based nuclear power plants have a mature control method for entering and exiting the control area, due to the sufficient space of land-based nuclear power plants, the layout of the entrances and exits of the control area is complicated, which is not completely suitable for nuclear-powered ships. Therefore, it is necessary to fully consider the characteristics of nuclear-powered ships. Propose a fully functional access control method suitable for nuclear-powered ships to effectively prevent the spread of radioactive pollution and ensure personnel radiation safety

Abstract

The invention relates to the technical field of nuclear power ships, in particular to a nuclear power ship area arrangement structure which comprises a non-control area, a cold changing room, a hot changing room, a decontamination room and a control area. The cold changing room communicates with an access door of the non-control area; The hot changing room communicates with an access door of the control area; a one-way gate is arranged between the outlet of the cold changing room and the hot changing room; a pollution detector is arranged between the outlet of the hot changing room and the cold changing room; and the decontamination room is arranged in the internal compartment of the hot changing room and communicates with the hot changing room. A radioactive contamination area and a non-radioactive contamination area are physically isolated, radioactive contamination diffusion can be effectively prevented, precious space resources can be saved for nuclear power ships, enough places and articles can be provided for workers entering and exiting the control area, and meanwhile, radioactive contamination detection and decontamination can be carried out on personnel and articles leaving the control area.

Description

technical field [0001] The present application relates to the technical field of nuclear-powered ships, and in particular, relates to an area layout structure of nuclear-powered ships. Background technique [0002] Nuclear-powered ships are equipped with nuclear power devices, and their cabins are usually divided into control areas and non-control areas. Reactor cabins, sampling rooms and other places with high radioactive levels and prone to leakage of radioactive materials are usually located in the control area. [0003] Due to limited space, nuclear-powered ships usually do not fully consider the control method of entering and exiting the control area, and do not set up special facilities for the control of entering and exiting the control area. However, as people have higher and higher requirements for radioactive pollution protection, in order to To effectively prevent the spread of radioactive pollution, nuclear-powered ships also need a complete control method for e...
