14.7 VITRIFIED WASTE PRODUCT SHIPPING CASK
Vitrified high level waste product overpacks are to be stored
over a period of nearly thirty years prior to their deep geological
disposal.
Presently vitrified waste product overpack produced at WIP,
Trombay will be located at Solid storage and surveillance facility
(SSSF) Tarapur which is nearly 150 km away from Trombay.
Actual 9m-corner drop test on a scale
down model of shipping cask
Validation of deformations by FEA
A shipping cask weighing approximately 26 tons has been designed
to transport these vitrified waste product overpacks satisfying
all the regulatory requirements of Type B (M) packages for
transportation of high level radioactive material through public
domain.
As a regulatory requirement, 9m drop tests at different
orientations on an unyielding target surface and 1m drop on a
rigid punch have been carried out. FEA model has proved that
the deformations and stresses, energy absorbed, deceleration,
rigid wall forces in various components are within acceptable
Simulation curves for 9 m Corner Drop
limits. Validation of analytical models has been carried out by
actual drop testing of scale down models up to a limit of 1:4
u s i n g h i g h - s p e e d p h o t o g r a p h y, s t r a i n g a u g e s a n d
accelerometers.
