The Schedule And Risk Control On The X Plant For The Second Phase Of Hainan Nuclear

Hainan nuclear power plant in San Lian village, Hai Wei Zhen, Changjiang Li Autonomous County, Hainan Province, the project in October2009get access to start the preparation of approval, and in April25,2010officially started, first phase of the project contain two65kilowatts pressurized water reactor, using more mature "second generation of improved type reactor type, plans to invest190million yuan. According to the early planning and design, investment in nuclear power plants in Hainan to build four units65MW pressurized water reactor, completed in two phases, including a period engineering2units, originally planned in December2009officially started construction and by the end of2014completed installation and commissioning,2015April put into commercial operation. Due to the influence of various factors, resulting in Hainan nuclear power project a project schedule delays, a phase of the project has just entered the commissioning phase, failed to complete the original plan completed by the end of2014debug target. At the same time due to the construction and installation of the delay, the construction of the project and the original time to the original plan was postponed for five months. To delay the construction factors of project analysis, in project schedule control and risk control of X plant as an example, the analysis of the network graph on the duration of the project plan, reasonable arrangement of process activities, make full use of the construction enterprise construction experience and technical ability, the delay factors are analyzed and summarized, the influence factors of X plant construction process may exist in the future anticipation, the use of PERT/CPM network plan, analyze the project schedule and process activities, find out the key project line, using Crystall Ball software to simulate the probability analysis of the completion of the project within the time stipulated in the contract, the progress process of uncertainty analysis, the uncertainty of risk judgment process the project completed on time effect coefficient.In the process of risk control of project schedule, the factors causing the delay of the project schedule are early warning, and the measures of the delay period are analyzed.The design schedule risk early-warning model, through the establishment of early warning model of signal monitoring points in the network diagram on the critical path, through the current monitoring signal judgment, analysis of project progress, then the current monitoring progress and a monitoring point comparison, analysis to determine the delay is to continue to expand or shorten, through the conclusion of the model, the factors causing schedule delay analysis, early warning results visualization, risk the color representation way, warning degree of risk, to varying degrees of delay corresponding to green, yellow, orange, red four colors, the model is able to do early warning project delays, solve the schedule delay judgment lag, improve schedule management level, but also enhance the risk management ability, is conducive to the management to take measures to eliminate the risk factors.
