International Structure for Decommissioning Costing (ISDC) of Nuclear Installations jointly issued by OECD /Nuclear Energy Agency (NEA), International Atomic Energy Agency (IAEA) and European Commission (EC). Complete document in PDF format is available

Cost estimation for the decommissioning of nuclear facilities can vary considerably in format,
content and practice both within and across countries. These differences may have legitimate reasons
but make the process of reviewing estimates complicated and the estimates themselves difficult to defend.
Hence, the joint initiative of the OECD/NEA, IAEA, EC was undertaken to propose a standard itemisation
of decommissioning costs either directly for the production of cost estimates or for mapping estimates
onto a standard, common structure for purposes of comparison. The published International Structure for
Decommissioning Costing (ISDC) of Nuclear Installation updates the earlier itemisation published in 1999
and takes into account experience accumulated thus far. The revised cost itemisation structure has sought
to ensure that all costs within the planned scope of a decommissioning project may be reflected.
ISDC is considered as:
At the highest Level 1, eleven Principal activities are identified:
01 Pre-decommissioning actions
02 Facility shutdown activities
03 Additional activities for safe enclosure or entombment
04 Dismantling activities within the controlled area
05 Waste processing, storage and disposal
06 Site infrastructure and operation
07 Conventional dismantling and demolition and site restoration
08 Project management, engineering and support
09 Research and development
10 Fuel and nuclear material
11 Miscellaneous costs
ISDC can be used for:
