Development of a Type C package for the transport of radioactive material with no restrictions on activity by different transport modes including aircrafts
The Type C package shall maintain its containment upon impact onto a target at a velocity of 90 m/s (this is similar to a fall from a height of 450 m).
The overpack for this packaging based on the Czech-made SKODA VPVR/M cask was developed by R&D Company "Sosny" jointly with RFNC-VNIIEF.
The work was done under the U.S./Russia Research Reactor Fuel Return (RRRFR) program under Order of the U.S. Department of Energy aimed to enhance safety of air shipments of radioactive material.
This is the world's first Type C package for the transport of research reactor SNF by air.
In 2009-2010, different overpack layouts and structural materials were considered. Experts analyzed multiple options to select the optimum design, i.e. a vertical cylinder backfilled with hollow titanic balls made of two hemispheres with a flanged joint along the perimeter, which accommodates a SKODA VPVR/M cask.
In mid 2010, a concept design was finished and the package was assigned identification number TUK-145/C. In April, 2011, a preliminary design was agreed on with carries and the certification test enterprise. Its weight is 29,650 kg at a maximum charge of the spent fuel of 450 kg (up to 36 SFAs). The first energy absorption container for the TUK-145/C package was fabricated at the VSMPO-AVISMA Corporation. The package can be placed on a trailer, a railcar or in AN-124-100 or IL-76 cargo aircrafts.
The prospective use of the Type C package are individual shipments of high-level radioactive material and spent fuel for research or small batches of the spent fuel for reprocessing.
In May, 2011, the TUK-145/C mockup packaging (1:2.5 scale) was successfully tested on the rocket
sled at FSUE "RFNC-VNIIEF" for impact onto a target at a velocity of more than 90 m/s
In 2013, four air shipments of TUK-145/C casks loaded with the research reactor spent nuclear fuel were made: one air shipment is from Viet Nam and three air shipments are from Hungary.
