The article presents the results of a survey carried out at a storage facility for intermediate- and high-level waste established during the operation of MP and RFT research reactors at the site of the Russian Research Center Kurchatov Institute. Relevant survey methods were selected based on the personnel safety requirements for measurements, permissible individual and collective annual exposure of personnel and the population, standards for contaminated environmental objects. All RW containers held in the storage cells were certified and handled properly to ship them from the site of the RRC Kurchatov Institute. The decommissioning designs for this storage facility will be developed based on the data obtained.
The article presents the technologies applied during the dismantlement of building structures and auxiliary systems in the central hall of MR research reactor at the site of NRC Kurchatov Institute. Contaminated structures and systems were mainly removed using remote methods and power-supplied equipment. The latter ones were selected based on safety requirements, compliance with environmental standards that accounted for the location of the reactor in a densely populated area of the Moscow city. The project was aimed at providing the compliance of MR reactor hall with the criteria specified in the decommissioning designs and describing its final state. The paper summarizes the key results and recommendations on the radiation safety of RW management, as well as the lessons learned during the performed operations seeking for their further application at other facilities.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
