RBMK-1000 spent nuclear fuel transfer from wet to dry storage
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.
