The Decommissioning Mock-up Test Field is available for verifying or demonstrating research achievements obtained in the Dismantling Technology Demonstration Field and the Laser Processing Test Field, and cutting technologies in-house developed by local companies with actual equipment and mock-up materials used in “Fugen”. The field can also be used for pre-confirmation, experience and acquisition of dismantling work.
The Mock-Up Test Room in this field consists of “Technical Demonstration Test Area for the Underwater” and “Technical Demonstration Test Area in Air Atmosphere”.
In the Technical Demonstration Test Area for the Underwater, a cylindrical water tank with a height of about 10.5m is placed, and a Seven-Axis Remote Underwater Robot is installed in the cylindrical water tank. Water level in the cylindrical water tank can be arbitrarily adjusted below 10m to the test condition, and a water circulation and a purification system is equipped with the tank.
One example of demonstration experiments involves placing a simulated material in the cylindrical water tank as a high-dose reactor structure and cutting it with the remote-controlled articulated underwater robot equipped with a laser cutting head attaching on the tip.
In addition, there are many similar storage tanks in the nuclear facilities. In this area, the work environment for dismantling and welding those tanks can be simulated and safe and efficient working methods can be confirmed and acquired in advance.
The Technical Demonstration Test Area in Air Atmosphere －the Laboratory of Technical Demonstration Test in Air Atmosphere－ has approximately 4m in ceiling height, 5m in width and 7m in depth. The laboratory has a built-in smoke exhaust device, and the working environment is taken into consideration to be able to maintain cleanliness of the inside area by collecting the fumes and dust generated by cutting.
The Laboratory can be used for the following purposes with the simulant materials and the actual materials used in “Fugen”:
-Collecting the fumes and dust generated by cutting, and acquiring and verifying data on a particle size distribution
-Demonstrating remote-controlled cutting technology by a Six-Axis Remote Aerial Robot
-Verifying the capability of cutting tools and various devices uniquely developed by local companies
-Pre-confirmation and acquiring work skills for dismantling and decontamination work including cutting and disassembling with cutting tools such as a general-purpose diamond wire saw and abrasive tools
-Work management experience and practice using a green house and protectors actually used on the dismantling site
The decommissioning work requires the same level of safety management and work management as in-operation. This field can be used by local companies planning to enter the decommissioning business as a place to confirm the methods and processes of dismantling work such as cutting and disassembling equipment, as well as decontamination work and acquire the related technique in advance.
Moreover, it is very useful to verify whether devices and industrial tools in-house developed by local companies are usable on the actual site.
