[en] Decommissioning and dismantling operations are often time taking and complicated. In this context, the development of new industrial processes is crucial to carry out the work faster, safer and in a more efficient way by minimizing waste volumes. Laser technology is commonly used and is based on shot blasting or electro/chemical decontamination. Although successful, these methods suffer from poor efficiencies and/or significant waste volume production. Laser ablation technology is one possible answer. Neither chemicals nor mechanical process are needed and thus no other waste than the contaminated materials themselves are generated. AREVA has been working on this new technology since 2007 and has performed numerous successful and fruitful trials (cold / hot) since. For the decontamination of the internal parts of pipes, two different routes can be used. A first one based on the chemistry as it was done for example at La Hague reprocessing facility or a second one based on machining as it was imagined for the dismantling of the Hall 71 at Marcoule site. In both cases, AREVA has developed processes or tools in order to achieve those operations. It is also important to focus on waste pre treatment solutions to allow various exotic wastes to meet the acceptance criteria for final disposal. AREVA has performed trials that demonstrate that solidification through polymers (NOCHAR products) can constitute an adapted pre-treatment solution for exotic waste to comply with disposal sites acceptance criteria (eg ANDRA). Among those exotic low-level and very low level radioactive waste are the ROL (Radioactive Organic liquids) and various organic and mixed organic/aqueous waste
