eOMEGA - ISDC Decommissioning Costing Platform

Abstract

The purpose of the paper is to present the results of development of the ISDC based eOMEGA platform used for decommissioning costing of nuclear facilities. The International Structure for Decommissioning Costing (ISDC) of Nuclear Installations (issued in 2012) is the costing format recommended by the IAEA, OECD/NEA and European Commission. Implementation of the ISDC enables transparent presentation of decommissioning costing data in the harmonised international data format.The basic idea behind the eOMEGA development is to merge the advantages of two existing matured solutions: the decommissioning costing software OMEGA and the web-based ADIOS platform with tools and processes to implement any web-based software solution with user- friendly interface. Moreover, the eOMEGA costing platform is intended to be one of the modules of the universal eOMEGA platform which covers also the other activities within the back-end of nuclear power engineering.The methodology for decommissioning cost calculation in the eOMEGA is in line with the international recommendations and best practices, is completely based on the ISDC and is applicable for any type of nuclear facility. Previous experience with development of decommissioning inventory data, determination of input data, calculation of waste management parameters using unique system simulating the material and radioactivity flow were implemented to the eOMEGA. Main goal of the eOMEGA costing platform is to provide the flexible, user- friendly and internet based tool for transparent decommissioning costing in the ISDC format for any stakeholders involved to preparation of decommissioning projects. Costing cases may be graded from preliminary up to the detailed costing at the level of final decommissioning planning. Access by any authorities/stakeholders may facilitate building of confidence in the decommissioning cost estimates and understanding the cost elements.
