STANDARD REGULATIONS
Holder of permit (licensee) for selection of site, design, construction, commissioning and licensee for nuclear facility operation develop initial and interim concepts and plans for nuclear facility decommissioning.
Stressing on the ethical principles – not to accrue burden on future generations in result of today’s generation activities – requires speeding up of decommissioning process.
Nuclear facility decommissioning is based on a concept used as a basis for choosing optimum and safe option for main activities performance and implementation phases during decommissioning.
