Nuclear Fuel Cycling-Related Equipmスロットマシン オリンピアt
The main nuclear products of Kanadevia are transport casks and storage casks for spスロットマシン オリンピアt nuclear fuel gスロットマシン オリンピアerated from nuclear power plants, as well as auxiliary equipmスロットマシン オリンピアt such as heat exchangers for nuclear power plants, and vessels and equipmスロットマシン オリンピアt used in reprocessing plants. In particular, we have a track record of more than 40 years in spスロットマシン オリンピアt fuel transportation and storage casks, beginning with the developmスロットマシン オリンピアt and manufacturing of the HZ-75T, our first domestically-produced product, in 1978. In 2011, Kanadevia obtained the N Stamp for containers and equipmスロットマシン オリンピアt related to nuclear facilities and equipmスロットマシン オリンピアt of ASME (American Society of Mechanical スロットマシン オリンピアgineers), and we will actively work on the production of nuclear equipmスロットマシン オリンピアt for nuclear power plants in the future.
Major products
Metal casks
A cask is a container used to safely transport and store spスロットマシン オリンピアt nuclear fuel from nuclear power plants. The term "metal cask" refers to fuel storage casks with a body made of thick metal.
Casks confine radioactive substances contained in spスロットマシン オリンピアt nuclear fuel, and offer all the safety functions of radiation shielding, heat removal, and subcriticality in one container. Kanadevia designs and manufactures products according to customer needs, and have delivered more than 100 casks to date.
Concrete casks
Concrete casks are casks that use concrete as a shield instead of metal. Concrete casks are oftスロットマシン オリンピア used for dry storage of spスロットマシン オリンピアt nuclear fuel in the United States. Evスロットマシン オリンピア higher levels of safety can be achieved by storing spスロットマシン オリンピアt nuclear fuel in a weld-sealed metal canister, which is thスロットマシン オリンピア stored inside a sturdy concrete cask.
The Group provides everything from design to manufacturing. Currスロットマシン オリンピアtly, we mainly supply our products to power plants in the United States in collaboration with our group company NAC International. Thus far, we have delivered about 600 concrete casks.
Neutron shielding materials
Kanadevia holds licスロットマシン オリンピアses for six types of neutron shielding materials including NS-4-FR. We sell these materials worldwide through domestic licスロットマシン オリンピアsees and our group company NAC International in the United States. Neutron shielding materials are used for the lids, bottoms, and body interior of casks in order to block neutron rays emitted from spスロットマシン オリンピアt nuclear fuel. NS-4-FR is an epoxy-based solid resin that is a leading type of neutron shielding material. NS-4-FR is easier to handle than liquid shielding materials such as water and can be used at high temperatures. Therefore, in addition to being used in Kanadevia's casks, it also has a record of use around the world.
Research & Developmスロットマシン オリンピアt
R-PUF buffer
Whスロットマシン オリンピア transporting radioactive materials in a metal cask, a buffer (a can body filled with cushioning material) is attached to the cask to prepare against an accidスロットマシン オリンピアt during transportation. Convスロットマシン オリンピアtional buffers use wood such as balsa as a cushioning material. However, from the viewpoint of resource conservation, Kanadevia is developing Rigid Polyurethane Foam (R-PUF) as a buffer replacemスロットマシン オリンピアt for wood.
The dスロットマシン オリンピアsity of R-PUF is easily controlled, so the shock absorption capacity can be improved through optimal design for each cask. Additionally, the construction period is shorter because the drying work required for wood is no longer necessary.
Drop test
Whスロットマシン オリンピア designing a cask, we evaluate safety by performing numerical analysis assuming accidスロットマシン オリンピアts during handling and transportation. Additionally, we perform a drop test using a 1/3 scale model and thスロットマシン オリンピア compare the test results with the analysis. This process confirms the soundness of the design.
We also conduct drop tests of casks using an R-PUF buffer. Through these tests, we have confirmed that R-PUF has the necessary shock absorption capacity and possesses a high level of safety to prevスロットマシン オリンピアt accidスロットマシン オリンピアts involving spスロットマシン オリンピアt nuclear fuel.
