Abstract

The invention provides an environmental influence coefficient calculation method, a nuclear power plant serious accident radioactivity acceptance criterion determination method and a nuclear power plant serious accident radioactivity acceptance method. By analyzing the reference release amount and the radiation consequence of the radionuclide after the serious accident of the nuclear power plant,the equivalent environmental influence coefficient of the representative radionuclide grouped by the radionuclide of the nuclear power plant is calculated; a radioactivity acceptance criterion of thenuclear power plant designed for the serious accident is determinined according to a general optimization intervention level specified by GB18871, and safety acceptance is performed on the serious accident of the nuclear power plant based on the acceptance criterion of the nuclear power plant designed for the serious accident. The problem that an acceptance criterion for radioactive consequences caused to the environment after serious accidents is lacked in existing nuclear power plant design is at least solved, and the scientificity of nuclear power plant design is improved.

Description

technical field [0001] The disclosure relates to the field of nuclear technology, and in particular to an environmental impact coefficient, a method for determining radioactive acceptance criteria for severe accidents in nuclear power plants, and a radioactive acceptance method for severe accidents in nuclear power plants. Background technique [0002] The Regulations on the Safety of Nuclear Power Plant Design (HAF102-2016) incorporates severe accidents into the Design Extension Conditions (DEC-B, Design Extension Conditions-B) for management, and requires that "the basic goal of safety design is technically Off-site protective actions to mitigate radiological consequences are limited or even eliminated." Obviously, the safety acceptance after a severe accident of a nuclear power plant is very important for the protection of the environment. However, there is still no unified acceptance criterion for the radioactive consequences to the environment after a severe accident. ...
