Next-generation decommissionning & waste management costing software based on ISDC

Create, update, manage and compare
decommissionning cost estimates
Easy-to-use software for estimating decommissioning and waste management costs with fully implemented internationally recommended ISDC structure and methodology.

What is eOMEGA?

The eOMEGA platform is a logical follow-up of our long term involvement of DECOM company in Slovakia (more than two decades) in the field of decommissioning planning and costing including the development of unique decommissioning costing codes. The motivation for eOMEGA platform development is to create the decommissioning costing tool taking into account following assumptions:

  • fully implemented ISDC structure and methodology to facilitate the harmonization, transparency and benchmarking in the decommissioning costing;
  • to meet the actual international recommendations and trends in costing;
  • applicable for any type of nuclear facility (power plant, research reactor, waste management facilities, etc.) with any systems, structures and radiological situation;
  • applicable for any phase of the decommissioning planning process starting from very preliminary costing during licensing of operation of the facility up to final decommissioning planning for licensing the decommissioning of the facility;
  • available to any stakeholder involved in planning and managing the decommissioning of nuclear facilities;
  • flexible, open, transparent, modern and user-friendly environment;
  • accessibility via internet and supported by secure internet technologies.

What it in fact does?

eOMEGA is the software that calculates costs for decommissioning of any type of the nuclear facility - power plants, research reactors, non-reactor facilities such as waste management facilities, fuel cycle facilities or laboratories. In other words, you can use the eOMEGA to determine how much will you have to pay for final phase of the nuclear facility life-cycle i.e. for transition period after final shutdown and for final decontamination, dismantling, demolition, site restoration, processing of all generated radioactive and non-radioactive waste and all related managing and supporting activities.

Results of costing are used also for establishment of the decommissioning funding schemes which is also included in the eOMEGA software.

Other key feature of the eOMEGA code is the possibility to calculate costs for waste management of almost any kind of waste. Flexible unique system for simulation of the real flow of materials and related radioactivity according to the user’s defined waste management scenarios was developed which included the versatile algorithm for configuration of user’s specific waste management technologies.

Key features

  • Inventory database with the specific facility structure of systems, components and civil structures and the concept of radio-nuclide vectors for flexible definition of radiological parameters of inventory items respecting the decays
  • ISDC based cost calculation methodology developed in-house (taken over also at the IAEA)
  • Detailed costing results in ISDC format
  • Benchmarking and sensitivity analysis of decommissioning costs
  • Export & import of costing cases
  • Use of costing results for development of decommissioning funding schemes and related funding data
  • Customised waste management scenarios and waste management technologies--
  • Secure client-server architecture
  • ... and everything in a simple user interface

Who is it for?

Nuclear power plants

A nuclear power plant is a thermal power station in which the heat source is a nuclear reactor. As is typical in all conventional thermal power stations the heat is used to generate steam which drives a steam turbine connected to an electric generator which produces electricity.

Waste management facilities

Waste management is all those activities and action required to manage waste from its inception to its final disposal. This includes amongst other things, collection, transport, treatment and disposal of waste together with monitoring and regulation.


For the clean environment. Nuclear energy is considered to be the almost the cleanest energy and is the cheapest one. The key factor to this comparison is the quality of nuclear waste processing and storage. Better waste management means cleaner environment.

Research reactors

Research reactors are nuclear reactors that serve primarily as a neutron source. They are also called non-power reactors, in contrast to power reactors that are used for electricity production, heat generation, or maritime propulsion.

How the decommissioning costs are calculated?

eOMEGA uses internationally recommended structure (joint initiative of OECD/NEA, ISDC, EC) for presenting the cost for decommissioning projects - the “International Structure for Decommissioning Costing (ISDC) of Nuclear Installations” generally known under the abbreviation ISDC. For more information please read more about ISDC. Own costing methodology was developed that reflects specifics of the ISDC and the international best practice in decommissioning costing.
