DECOMMISSIONING

"RU BN-350"

Taking into account the uniqueness of this facility, its potential danger and the technological complexity of activitiesthe, it was developed and approved by Decree No. 200 of the Minister of Energy and Mineral Resources of the Republic of Kazakhstan dated 9 October 2003, "Basic Provisions for Decommissioning Project of RU BN-350". Pursuant to these provisions, all activites are grouped into five construction stages.

MANUFACTURING PROCESSES

Tasks of the first and second stages have now been almost completely solved and the reactor is brought into nuclear safe shutdown conditions METR, as the General Designer, starts to solve tasks related to development of design and detailed documentation per technology processes of conditioning and removal of radioactive waste, as well as preparation of RU BN-350 buildings, structures and engineering systems, and safe storage.. This facility was finally stopped in 1999. On 22 April 1999, the Government of the Republic of Kazakhstan adopted Decree No. 456 about on the RU BN-350 Decommissioning in Three Stages (the Concept of "Postponed Dismantling"):

First Stage. Bringinf of RU BN-350 into the safe storage conditions.

Second Stage. Safe storage (50 years).


Third Stage. Partial or complete dismantling of equipment, buildings, structures and disposal of radioactive waste.

POSTPONED DISMANTLING

The choice of the concept "Delayed Dismantling" is determined based on economic conditions in the Republic of Kazakhstan at the time of that decision. Federal Law as of 11 July 2011 No. 190-FZ "On Radioactive Waste Management". • Accumulated - Radioactive Waste generated before the effective date of the law. • Newly Formed - After the effective date of the law.
• New Classification (VLR, LRW, MRW, HRW) Decommissioning concept "Immediate Dismantling" is adopted for all nuclear energy facilities. LRW and MRW are disposed in surface-type RW landfill (60 m), HLW are disposed is buried at deep-laid RW landfill (500 m).
