A nuclear power project economic evaluation method based on full-life leveling and declaration

Abstract

The invention provides a nuclear power project economic evaluation method based on full-life level declaration. The nuclear power project economic evaluation method comprises the following steps: 1) determining basic attributes of a nuclear power station, a unit construction investment condition and a nuclear power project basic operation condition; 2) calculating the quasi investment cost LCOA, the quasi fuel cost LCOF and the quasi operation and maintenance cost LCOO according to the parameters determined in the step 1); 3) calculating the level-to-level deduction power generation cost LCOE,wherein the LCOE = LCOA + LCOF + LCOO; 4) carrying out sensitivity analysis and risk analysis; and 5) comparing according to the calculated level-to-level implicit power generation cost LCOE by referring to a compared target, and combining a sensitivity analysis result and a risk analysis result to obtain an evaluation conclusion. According to the method, on the basis of reproduction of the powergeneration cost and the grid-connected electric quantity of the nuclear power unit in the whole life period, the important indexes representing the economical efficiency are calculated, namely, the generation cost is reproduced in a leveling mode, the relevant stipulations of domestic energy targets can be met, the calculation process can be convenient and fast, and meanwhile the method is in line with the conventional economic evaluation method of international organizations.

Description

technical field [0001] The invention relates to the technical field of economic evaluation of nuclear power projects, in particular to an economic evaluation method for nuclear power projects based on life-cycle levelization discounting. Background technique [0002] For my country's nuclear power projects, a consistent and definite economic evaluation method has been formed in the industry. The National Energy Administration has issued the standard "Economic Evaluation Method for Nuclear Power Plant Construction Projects" (NB / 20048-2011). This standard inherits the "Construction Project Economic Evaluation Method and Parameters". The specific evaluation method is: based on the construction investment of nuclear power projects, predicting reasonable operating conditions, calculating operation and maintenance and fuel costs based on contract conditions and historical experience, and ensuring cost recovery, Under the premise of fulfilling the loan repayment contract, legal ta...

Problems solved by technology

However, the inventor found through research that taxation and other policies have been considered in the calculation of the levelized cost of power generation in the photovoltaic industry, and at the same time the method has been greatly changed, partly out of the true meaning of the levelized discounted cost of power generation

[0005] At the same time, due to the simplification and deformation of the calculation method of the levelized discounted power generation cost of international organizations, the relevant domestic units have insufficient understanding or even deviation of the method, and it is difficult to learn from it or apply it accurately.

In the process of promoting the nuclear power industry to go global, there is no economic evaluation method that can be referred to, which can not only meet the relevant regulations of domestic energy standards, but also realize the convenience and speed of the calculation process, and at the same time be in line with the economic evaluation methods commonly used by international organizations. The phenomenon has greatly restricted the development of China's export work
