11 Casks Designed by ŠKODA JS ŠKODA 1000/19 Cask Dual-purpose cask for transport and long term dry storage of spent fuel of the type VVER 1000 with enrichment of up to 5 wt% U 235. Contract Signed in 2015 Totaly 58 pcs to be delivered by 2035 License By SUJB in 03/

12 Casks Designed by ŠKODA JS 1. Cask Body Steel forging with inserted neutron shielding in form of PE-rods. Cask body surface is mantled with cooling ribs ensuring transfer of residual heat to ambient environment. Cask outer surface is covered with anticorrosion coating. Sealing surfaces are plated with welded stainless steel and then machined. Inner cavity walls are coated with metal alloy. 12

13 Casks Designed by ŠKODA JS 2. Lids Ensuring Tightness of Inner Cask Space Cask innner space is hermeticaly closed with 2 stainless steel lids, both with two gaskets. Cask tightness is permanently monitored using pressure transducers. 3. Trunions for Cask Handling The Cask is equipped with 4 trunions in upper part for cask handling and with 2 trunions for tilting from/to upright position. Trunions are made of stainless steel forgings, they are bolted to the cask body. 13

14 Casks Designed by ŠKODA JS 4. Fuel Basket ŠKODA 1000/19 Basket consists of 19 hexagonal tubes made of aluminum alloy with B 4 C content. Boron contained in Al-alloy ensures neutron absorption and thus the subcriticality of the inserted fuel. Aluminum rods inserted in corners of hexagonal tubes ensure better basket stability at the dynamic strain. The tubes are bolted together. Basket capacity is 19 FA. Bottom of the basket is fixed with the closing plate. 14

15 Casks Designed by ŠKODA JS 5. Shock Absorbers Both ends of the cask are equipped with shock absorbers at the transport (part of the transport vehicle) in order to preserve the cask against damage at the postulated 9 m drop. AAAAAAAA 15
