Research On Equipment Supervision Quality Evaluation Of S Nuclear Power Plant

The safe development of nuclear power is an important measure for China to face energy shortage and climate problems.China’s 14th Five-year Plan and the 2035 long-term goal outline point out that the construction of coastal nuclear power should be promoted safely and steadily.Nuclear power plants are integrated by tens of thousands of equipment,and the safety of nuclear power plants is largely determined by the quality of the equipment.The construction organization of nuclear power plant attaches great importance to equipment quality management and carry out equipment supervision in the equipment manufacturing process.However,with the gradual improvement of the construction standards of domestic nuclear power stations,and the continuous emergence of new types of reactors,the equipment supervision work has also posed new challenges.At the same time,after the Fukushima accident,it experienced a "conservative period" of nuclear power,there is a large area of loss of supervision personnel each company.With the increase of new nuclear power units in recent years,new supplementary personnel are faced lack of skills and practical experience.How to improve the supervision level of equipment manufacturing and ensure that the quality of equipment safely has become an important task of equipment procurement management of construction organization in the future.This paper evaluates the construction quality of S nuclear power plant.From the perspective of nuclear power plant construction unit,this paper evaluates and studies the construction quality of S nuclear power plant equipment,aiming to improve the quality management ability of nuclear power plant construction.Firstly,this paper summarizes the foreign and domestic research literature and finds that they have hardly studied the evaluation of equipment supervision quality from the perspective of construction units.Secondly,the current situation of equipment supervision and management of S nuclear power plant is studied,and the management mode,content and problems of S nuclear power plant equipment supervision are explained.Then the three-level evaluation index system and evaluation model of S nuclear power plant equipment supervision are constructed by hierarchical analysis and fuzzy mathematical method.Finally,taking the first phase of the S nuclear power plant nuclear island project as an example,the evaluation index system and model were applied and verified,and the evaluation index system and model were applied,and the problems in the supervision and management of S nuclear power plant equipment were found,and suggestions for improvement were put forward.From the perspective of supervision and management of construction units,it is a new practice to carry out the quality evaluation of equipment supervision and construction in the industry.By building a scientific and reasonable nuclear power equipment supervision quality evaluation model,the first phase of S nuclear island nuclear equipment supervision management and implementation of the evaluation work,found the weaknesses in the process of supervision management,pointed out the direction for the equipment manufacturing quality effectiveness improvement,is advantageous to the S nuclear power plant construction unit to improve the management level of equipment supervision,make it can better guarantee the quality of equipment manufacturing,improve the equipment safety.
