The Ningyo-toge Environmental Engineering Center, the Japan Nuclear Cycle Development Institute had carried out research and development projects related to the front-end of the nuclear fuel cycle and has shifted its project to the environmental protection measures including decommissioning and dismantling facilities since reorganization in 1998. It was decided by the Japanese Government that a new entity would be established merging JNC and Japan Atomic Energy Research Institute, within the context of the overall reform of government-funded organizations by 2005. This draft of prospective plan of the Ningyo-toge has discussed because we are in the preparation phase for the merger with the discussion being made on the role and management of the new entity.

Technology developments for the decommissioning of uranium fuel facilities and the treatments of uranium wastes are one of the current main projects in the Ningyo-toge Environmental Engineering Center of the Japan Nuclear Cycle Development Institute (JNC Ningyo-toge). In order to carry out the project reasonably and safely, all techniques from decommissioning to waste treatment should be unified systematically. Thus, the JNC Ningyo-toge is aiming at the establishment of a 'decommissioning engineering'. This booklet illustrates the decommissioning engineering, especially four engineering elements; that is, a removal technology for uranium compounds, a decommissioning technology of the centrifuges, an application of CaF2 precipitate and a decommissioning engineering system.
