Embodiment 1

[0097] The present invention takes a generator set as an example to construct a nuclear power safety operation index system, and evaluates and analyzes the safe operation status of No. 1 unit according to the measured data in 2006.

[0098] (1) Construction of index system

[0099] The index system for safe operation of nuclear power plants is shown in Table 1. The index system includes a target layer, a rule layer, and an index layer. Among them, the target layer is the safe operation status of nuclear power plants, and there are four indicators in the rule layer, namely, operational performance, occupational exposure, and radioactivity. Emissions and operational events, the index layer includes unit capacity factor, unit load factor, per capita effective dose, collective effective dose, inert gas emissions, halogens and aerosols, tritium, other nuclides, 0-level operational events, and 1-level operational events.

Abstract

The present invention belongs to the nuclear power plant safety operation assessment technology field, and especially relates to a nuclear power plant safety operation assessment method based on an entropy evaluation method and a matter-element extension method. Aiming at the development and safety operation condition of the nuclear power in our country, in order to realize comprehensive and systematic assessment for the nuclear power plant safety operation condition, the present invention provides a nuclear power plant safety operation assessment method based on an entropy evaluation method and a matter-element extension method. The method comprises: establishing a nuclear power plant safety operation condition index system, constructing a matter-element extension model to obtain association degree of each index on related assessment grades, combining the association degree and the entropy evaluation method, and solving a weighting comprehensive association degree so as to determine the assessment grade of the safety operation condition of the nuclear power plant. The nuclear power plant safety operation assessment method based on the entropy evaluation method and the matter-element extension method realizes classified assessment of each index of the safety operation condition while realizing comprehensive assessment of the whole operation condition of the nuclear power plant and takes the actual data in the assessment process as a basis so as to overcome the subjectivity of a fuzzy comprehensive assessment model and allow the assessment result to be more practical and reliable.

Description

technical field [0001] The invention belongs to the technical field of safety operation evaluation of nuclear power plants, and in particular relates to an evaluation method for safety operation of nuclear power plants based on an entropy value method and a matter-element extension method. Background technique [0002] With the rapid development of my country's nuclear power industry, nuclear power safety has become an important foundation for the development of the nuclear power industry. my country clearly pointed out in the "12th Five-Year Plan for Nuclear Safety and Radioactive Pollution Prevention and Vision and 2020 Long-term Goals" that "in order to achieve the planned goals, promote the technological upgrading and progress of nuclear energy and nuclear technology utilization, further eliminate potential safety hazards, and improve nuclear safety. Plan to implement key projects such as safety improvement, pollution control, technological innovation, emergency support a...
