Research On The Cost-Reduction Strategy For Equipment Procurement Of Xudapu Nuclear Power Plant

The first phase of the Xudapu Nuclear Power Plant adopts the US AP1000 third-generation nuclear power technology.The engineering construction adopts the EPC(Engineering Design,Procurement Construction)general contracting mode.The engineering company is responsible for the project design,item procurement and project.Civil construction installation and commissioning work.The engineering company should gradually establish a equipment procurement management system applicable to the Xu Dapu nuclear power project based on the experience of the AP1000 demonstration project and combine its own practice to better serve the owners and projects.Based on the equipment procurement status of the demonstration project and other nuclear power projects of the EPC general contractor,this paper takes the equipment procurement under the EPC general contracting mode of the Xudapu nuclear power plant as the entry point,based on the cost control theory,procurement management theory,and application literature.Research methods,case analysis methods,quantitative and qualitative research methods,etc.,in-depth analysis of the reasons for the high cost of equipment procurement in the construction of nuclear power projects,summed up "over-optimization of design,change integration is not in place","lack of suppliers Restrictive means,some suppliers use raw material prices to report false high prices,"unreasonable contract terms,lack of effective means to deal with changes in the external environment,resulting in an increase in overall costs","high management costs of contract execution",etc.,affecting procurement costs The main factors are proposed in the EPC mode,"control equipment purchase price","optimized procurement model","improvement of comprehensive management level","promoting localized office","promoting localization" and other equipment procurement suitable for AP1000 batch construction Cost control strategy to improve management of equipment procurement Workflow,research measures and methods to control costs of equipment purchases under EPC mode,in order to ensure the implementation,from the outside,inside both developed safeguards.The external focus is implemented from three aspects: national strategy,industry standards,and contract guarantee;internal protection from the EPC contractor system and procedures,the creation of cost center management concepts,implementation of sand table deduction,etc.,to support the implementation of cost control measures.This paper focuses on the cost-reduction strategy of equipment procurement under the EPC mode of Xudapu Nuclear Power Plant.The purpose is to use the Xudapu project as a model for domestic AP1000 independent construction,and to provides reference on purchasing equipment for the future construction of AP1000 and even more advanced nuclear power projects.
