Nuclear Power Plant IDS Commissioning Project Planning And Controlling

China currently has a total of 27 units in the construction and 23 units in the operation of nuclear power plant,has become the first in the scale of the construction,the fourth in the capacity of the world's nuclear power.However,the current nuclear power project progress management has not formed a standard,how to plan and control the nuclear power project schedule is still in the exploration stage.The Sanmen nuclear power plant uses the third generation AP1000 advanced pressurized water reactor technology.As a third-generation AP1000 nuclear power technology application and implementation of the world's first reactor,due to the complex organization,no reference plants,involving a wide range of expertise and other factors,progress management of commissioning project in Sanmen encountered unprecedented challenges and difficulties.In this paper,the network planning technology(CPM/PERT)and critical chain(CCM)advanced methods are applied to Sanmen nuclear power project management.Class 1E DC and UPS system(IDS)in AP1000 for example,how to plan and control the schedule of IDS commissioning project are discussed,mainly solved the four problems: first,the time limits for the no reference projects are estimated by Delphi method and PERT.The two is to solve the resource conflict by optimizing the organization and adding constraints.The three is adding project process risk management before project started.The fourth is using buffers in project controlling to avoid project process delay.Finally,through the empirical analysis,this method can solve the actual problem of AP1000 IDS commissioning project,and can effectively track and control the progress of project,which is a useful attempt in nuclear power project management.
