FIELD: nuclear power engineering.

SUBSTANCE: invention relates to handling casings with irradiated fuel assemblies (IFA) in SNF storages on floating maintenance bases (FMB) and coastal maintenance bases (CMB). Universal transfer protection container comprises an outer cylindrical housing with trunnions and a concentrically arranged inner central tube. Between them there is a material of biological protection containing lead, a louver gate with a rotary plug closing a hole in the lower part of the central tube, and a grip with a cargo rope for movement of the casing inside the housing. In particular case of the declared container the cargo rope is connected to the grip through a swivel to prevent its spinning off.
