摘要： PROBLEM TO BE SOLVED: To improve the efficiency in the storage of spent fuels whose heat release is low by using a single cask, housing a single canister in the cask and stacking baskets stowing the spent fuels in layers in the canister. SOLUTION: A single long one is used for either of a concrete cask 1 and a canister 2, and two pairs of short baskets 3 where spent fuels 4 are inserted and supported respectively are provided. In a main body 2a of the canister 2, the baskets 3 are stacked in two layers and the basket 3 in the lower layer is housed in the canister 2 and is supported on the bottom face of it. Moreover, a support plate 20 welded to the entire inner perimeter of the main body 2a of the canister 2 is formed in the upper part of the basket 3 in the lower layer so as to sit at about the midpoint position in a vertical direction in the main body 2a of the canister 2. The basket 3 in the upper layer is housed in the canister 2 and is supported on the support plate 20.

摘要： PROBLEM TO BE SOLVED: To surely shield the dispersion of radiation from a canister in the entire operation process by providing upper and lower shielding bodies for shielding radiation between the upper and lower parts of the canister and between a lid and a bottom plate. SOLUTION: For example, when a cask 1 accommodating a canister 30 is to be carried into a storage location by a trailer, the cask 1 is tentatively installed on a stand, a lid 5 is removed along with an upper buffer body 10, a suspension tool being connected to a crane is suspended at a suspension part 16 of a lid 15 of a protection cylinder 19, at the same time, the suspension tool is hooked also to a trunnion 6 of the cask 1. The cask 1 and the canister 30 are suspended by a suspension tool, and at the same time, a bottom plate 9 of the cask 1 is removed and is carried to a storage location where an accommodation pipe exists by the crane and the suspension tool. On transportation, the canister 30 is accommodated in the protection cylinder 19 and at the same time an upper side is shielded by an upper shielding body 13 and a lower shielding body 14. Also, since the canister 30 can be inserted into the accommodation pipe at the accommodation location while the bottom plate of a transportation container is removed, thus easily inserting the canister 30 by its gravity.

摘要： PROBLEM TO BE SOLVED: To provide a transport vessel capable of safely housing radioactive material even in case of fall of a canister. SOLUTION: The transport vessel of radioactive material comprises a canister housing the radioactive material in the inside, and a cylinder housing the canister 16 in the inside. A liquid chamber 7 is formed between the inner peripheral face of the inner cylinder 2 and the outer peripheral face of the canister 16, and in the case where the hanging canister falls, buffing liquid in the liquid chamber absorbs impact. In addition, it is preferable that a liquid chamber 6 is formed between the inner face of an inner cylinder bottom part 2a and the outer face of a canister bottom part 16a.

摘要： PROBLEM TO BE SOLVED: To provide a new radiation rate measuring device for accurately measuring the radiation rate of an electrical heating element for discharging a high-level radiation such as a glass hardened body. SOLUTION: A device body 3 with a shielding wall 4 for shielding the high- level radiation of an electrical heating element 2 has a contact-type thermometer 5 for directly measuring the surface temperature of the electrical heating element 2, and a connection hole 10 is formed on the shielding wall 4. Further, the end face of the connection hole 10 has a non-contact type thermometer 6 for measuring the apparent surface temperature of the electrical heating element 2 for an arbitrary radiation rate by receiving the radiation of electromagnetic waves, and the above connection hole 10 has a shutter 11 for arbitrarily switching the hole 10, thus easily and accurately obtaining the radiation rate regardless of the electrical heating element for generating a high-level radiation such as a glass hardened body and hence accurately obtaining the amount of radiation heat transfer of the electrical heating element.

摘要： PROBLEM TO BE SOLVED: To improve the heat dissipation and housing capacity of a container in the storage of a solid waste and reduce the influence of impact and vibration at work by filling an interstice between an inner wall of a main body of the container and the solid waste with a highly thermal conductive granular filler and stacking up in a housing tube hermetical containers that are sealed with top lids after the charging of the filler to house and store them. SOLUTION: A solid waste P is loaded inside a main body 21 of a hermetical container 20, and an interstice between the main body 21 and the waste P is filled with a highly thermal conductive granular filler R. After the charging of the filler R, the main body 21 of the container is sealed with a top lid 22 and then hermetical containers 20 are housed and stored in a stacked-up condition inside a housing tube 5 in a storeroom. The container 20, which is formed of a stainless steel material, has the bottomed-cylindrical main body 21 whose outer surface is shaped cylindrically, the top lid 22 for opening and closing an upper opening 21a, a suspending part 23, a fastening part 24 where the top lid is attached and a skirt part 25. The upper opening 21a is formed by an inward flange F. Alumina granules and the like are selected for the filler R.
