Strategy of design improvements and low radioactive materials recycling to facilitate decommissioning

Analyzing the hypothetical costs of BN-800 decommissioning reveals that they can be reduced to a great extend on the base of radioactive danger criteria design optimization. At the same time we can decrease the optimal 'cooling down period'from 70-100 to 10-15 years. A lot of radioactive materials far under the level of unrestricted release in optimized variant makes it possible to 'reproduce' the reactor almost in the whole provided Closed Cycle of such materials were organized. Due to that, the reliable market of low-level materials and 'non-proliferation' principle for them may be put into practice. (authors)
