Application
The spent fuel casks in the shield cover can be transported and hoisted into the designated shaft according to the orders with the help of cask handling overhead crane. If necessary, the spent fuel casks are hoisted out of the shafts according to the orders, and handled into the shielded transfer casks through the transfer hoisting hole or transported to the loading position and returned the remaining fuel element to the reactor core by the method of suction.
