Embodiment Construction

[0055] The present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments, but these embodiments should not be construed as limiting the present invention.

[0056] from figure 1 It can be seen that the relationship between the inner area A and the outer area B of the underground nuclear power plant plume emergency planning area. figure 2 A schematic diagram of the airborne radioactive material release and atmospheric dispersion process is given. The airborne radioactive material is released into the reactor containment vessel 2 through the reactor core 1, and part of it leaks into the reactor building cavern 3 after a variety of radioactive material elimination measures. The radioactive material elimination device is also installed in the reactor building cavern 3, and there is a rock mass shielding layer 4 with a great thickness between it and the outside world. The leakage of radioactive material is a very slow and...

Abstract

The invention discloses an underground nuclear power station smoke plume contingency planning zone division method. The method comprises the following steps: establishing an underground nuclear power station characteristic database, scientifically selecting an initial event of an accident to improve the credibility of a computing method; establishing a cavern group structure database to put forward a natural rock shielding layer leakage assessment method; establishing a nuclear power plant environment factor database to improve atmospheric dispersion simulation accuracy. The disadvantage of the traditional smoke plume contingency planning zone is improved by use of the method disclosed by the invention, and a new necessary computing flow is put forward; the inner zone radius, the outer zone radius and the boundary shape of the underground nuclear power station smoke plume contingency planning zone can be accurately and scientifically assessed, and an important evidence is provided for the nuclear contingency planning of the underground nuclear power. The difficulty and cost of the nuclear contingency are minimized while guaranteeing the public security.

Description

technical field [0001] The invention relates to nuclear power technology, in particular to a method for dividing smoke plume emergency planning areas of underground nuclear power plants. Background technique [0002] The emergency planning area refers to the area established in advance around the nuclear power plant, where emergency plans have been formulated and emergency preparations are made, in order to take timely and effective protective actions to protect the public in the event of an accident at the nuclear power plant. In the event of a nuclear accident, emergency preparedness needs to be carried out in the emergency planning area. In the case of emergency intervention, it is convenient to organize effective emergency response actions quickly and minimize the possible impact of the accident on the public and the environment. Among them, the plume emergency planning area is an emergency planning area established for the exposure path of radioactive plume in the event...
