Research On Duration Of Construction Of HPR1000 Nuclear Power Plant Project

The high safety standard,complicated technology,complicated engineering interface,large investment and long construction period is the characteristics of construction of nuclear power plant.Nuclear power plant construction period will directly affect the total investment,and the quality and the safety of nuclear power plant construction.Nuclear power construction period has been one of the most concerned parties.HPR1000 nuclear power as the first reactor project and meet the technical requirements of China's three generations of nuclear power plants,without reference to the power plant duration,the study of HPR1000 duration and used to guide the construction have a great significance.This thesis basis of the traditional construction period and the characteristics of the network plan,use the Monte Carlo method to solve the PERT network plan.According to the characteristics of PERT network plan and the nuclear power project to determine the probability of network operation in the probability of distribution function,and determine the number of simulations by confidence.For the factors affecting the duration of nuclear power engineering,this thesis puts forward nine types of factors affecting the construction period of nuclear power construction by analyzing the factors affecting,and establishes the ISM model of the construction period of nuclear power plant construction,studies the influence period of construction period of nuclear power plant.Based on the mathematical model of the reasonable construction period of HPR1000 is established based on the explanatory structure model of the factors of the duration,use the software of crystal Ball on the HPR1000 reasonable duration of the mathematical model sovle the construction period to complete the probability and the main factors affecting the duration.The main factors influencing the construction period of HPR1000 project are obtained through the sensitive map of each operation.At the same time,the main influencing factors and explanatory structural model of the nuclear power station in China have been verified.The correctness and usability of the method are validated.This thesis calculates the reasonable duration of the construction of HPR1000 nuclear power by establishing the model[73,75]months.The impact of HPR1000 nuclear power construction period of the key operations-based equipment installation,raft-based construction,Om below the internal structure of the construction,hanging crane installation commissioning,thermal test.The main equipment installation and procurement related to the need to focus on the construction unit of nuclear power plant main equipment manufacturing progress and quality...
