Salii L. Cost Management Models and Methods in the time of Planning Decommissioning Projects of Nuclear Power Plants Units

The object of research is planning processes for decommissioning project of nuclear power station unit. A research objective is providing of the rational planning for decommissioning projects of nuclear power stations units on the basis of life cycle analysis, cost estimation and modeling of financing dynamics. Scientific significance of results is defined by that using of developed models and methods let to develop the decommissioning strategy such provide the safety of personnel and population. They help to plan recourses rationally, to estimate its cost credibly, to form budget and to provide necessary financing for decommissioning project of nuclear power plant unit. Practical significance is that developed models and methods can be used for nuclear energy objects which are decommissioned or will be decommissioned: in time of cost planning for projects works and definition needs in circulating assets, in tine of forming applied approaches for economic efficiency of particular organize and technicalactivities and the project in whole, for justification of assignment quota to fund of future project financing for decommissioning project of nuclear power plant unit. The scientific results of research are the following ones. For the first time the cost management model for the decommissioning projects of the nuclear power plants units has been developed. In contrast to existent models it helps to take into account the external economic factors and let to provide the required projects financing. The cost estimating methods of works implementation for the decommissioning projects of the nuclear power plants units have been improved. They take into account requirements on providing of nuclear and radiation safety and let to form a budget of the projects. The method of the life cycle choice for the decommissioning project of NPP unit has been got the further development. On basis of the application of different estimation criteria of project efficiency and multivariable analysis it helps to estimate decommissioning strategies of nuclear power plants units. Introduction is branch. Further dissertation results using is possible and reasonable in time of state programs and legal documents developing which contain recommendations concerning choice justification of decommissioning strategy, cost estimating and recourse planning of decommissioning projects of nuclear power plants units of Ukraine.
