The dry long-term storage facility (SFSF-2) is a chamber-type structure formed by cast-in-place steel-concrete walls, top and bottom floorings separated with lateral steel-concrete partitions to several chambers. The main task in the creation of the storage facility is to provide an efficient natural air circulation circuit. A broad scope of experimental and computation researches has been carried out to solve that scientific task. Special test benches have been designed to simulate thermal processes, air motion in the circuit of natural circulation and to verify, based on the research outcomes, computer codes 'Fluent' and 'Conrad' in terms of computation of temperature distribution within the facility's components. Computation outcomes of the RBMMK-1000 Fuel Assemblies temperature conditions within casks placed in chamber-type storage facility wells in case of uniform loading of the wells within the dry storage facility chamber in two tiers of casks with maximally possible decay heat capacity have shown that maximal fuel cladding temperatures are lower than those set by input requirements. © 2011 Inderscience Enterprises Ltd.

The process of RBMK SNF transfer from wet to dry storage includes: (a) SNF transport and handling operations at the NPP related with SNF preparation for the wet-to-dry storage transfer; (b) SNF cask delivery to the MCC by rail; (c) SNF transport and handling operations at the MCC; (d) TUK-109 and rail transport preparation for the next shipment to the NPP. The RBMK-1000 SNF handling technology presumes that SNF preparation for dry storage under any option to be performed at the NPP within the bay for SFA shearing and SNF loading to the steel-concrete container. A necessary infrastructure has been created at the MCC to receive RBMK-1000 SNF from the NPP site. The developed technology for RBMK-1000 SNF interim storage presumes in-container storage on NPP's specially arranged pads. At least two barriers to prevent radioactivity spreading to the environment and a necessary shielding to restrict radiation impacts on the humans have been provided at every SNF management stage. © 2011 Inderscience Enterprises Ltd.
