4) 40149 – CEA's radioactive waste and unused fuel inventory - Marcoule site example
Jean-Guy Nokhamzon, Marc Butez, Ddaniel Fulleringer, CEA (France)
In the field of clean up and decommissioning of nuclear facilities the knowledge of the radioactive waste and
unused fuel inventories is crucial. For CEA (French Commission in charge of Atomic Energy and Alternative Energies),
this knowledge is a key issue : in the short term for the flows stream lining as well as in the middle and long terms for
investment strategy in nuclear support facilities.
<strong>The</strong>se needs appear in a larger extent at the national scale in France, with the enforcement of two laws promulgated
in 2006 dealing with radioactive waste and with transparency in Nuclear Safety.
More generally, a precise and reliable knowledge of inventory and flow production forecast is indispensable to give
pertinent answers to the questions related to waste valuation. Thus, all these subjects are also worked out with our
authorities in charge of financial aspects because there are essential for the cost control of clean-up and decommissioning
projects CEA has to manage. In effect, in these projects, waste management represents a great part of cost and risk.
For all these reasons CEA has carried out an important work to collect all his waste and unsued fuel inventories. For
this reason we have developed a new "INFLUVAL" data base which will be combined with a softare featured with
coherency checking and analysis modules. Indeed, we must guarantee uniqueness and relevance of data coming from
decommissioning projects and facility managers.
As a consequence, in 2009 CEA Clean-up and Decommissioning Division has decided to perform, , a
comprehensive inventory of waste and unused fuel with the following objectives :
- Consolidation of stock and expected flows,
- Evaluation of reference costs
- Help to dimensioning and investment decision for facilities programs ( storage, waste conditioning facility,…)
- Validation of waste cost ratio.
In this paper we will take Marcoule as a more precise example. On this CEA center, heavy operations of clean-up
and decommissioning are carried out on the first French reprocessing plants –UP1-, and the related workshops.
<strong>The</strong>ses installations have been shut down in 1996. Since this date the main operations were focussed on definitive
shutdown and dismantling of equipments which were to be realized in priority in the goal of reducing radiological
activity and operating costs.
Thus, the consolidation of the inventory data is essential to valid a scenario and then to design facilities for the
following stages of the UP1 project.
5) 40258 – Management of historical waste legacy at NRG Petten�
Renate de Vos, Nuclear Research and consultancy Group (Netherlands)
Since the 1960s, the Waste Storage Facility (WSF) in Petten has been used to store radioactive waste. In 1993, the
Dutch government decided that all nuclear waste should be stored in the central storage facility COVRA (Dutch Central
Organisation for Radioactive Waste). This means that the drums with historical waste must all be opened, their contents
sorted according to intermediate- and low-level radioactivity and subsequently packed for transport to the COVRA
facility.
<strong>The</strong> intermediate-level radioactive waste processing Unit (HAVA-VU) has been designed specifically for this
purpose.
In this paper an overview will be given of the process of this HAVA-VU project in the last decade. Subsequently
the current status and path forward will be described. Also the chosen solutions for waste processing and characterization
will be discussed.
6) 40031 – Norwegian Support For Regulations Of Radioactive Waste Management From Uranium Mining
And Mill Tailings In Central� Asia

In Central Asia the radioactive waste comes mainly from uranium mining and milling, nuclear weapon testing and
nuclear power development and other ionizing sources. This waste was produced, to a greater extent, by the
military-industrial complex and the uranium and non-uranium industry, and, to a lesser extent, by the nuclear industry
and in the process of use of isotope products. Exploitation and mining of uranium and thorium deposits produce a large
amount of solid and liquid radioactive waste, as well volatile contaminants which need a proper management. In Central
Asia the wastes are mainly stored at the surface in large piles and represent a long-term potential health and
