MeteCNC® for Spent Nuclear Fuel Management
Posiva Oy is the world’s leading final disposer, set to begin the disposal of spent nuclear fuel in the deep bedrock repository ONKALO® in the 2020s using a portal-type MeteCNC® machining center.
The robotic machining station we designed and manufactured, shown in the image, with the MeteCNC® G-18-24-05 as its central component, has been installed in the Olkiluoto encapsulation plant. The machining station ensures the surface quality of the fuel capsule, the flawlessness of the welding, and the external dimensions of the capsules with hundredth-millimeter precision.
In the overall encapsulation process, the machining station’s most critical task begins after the final disposal capsule has been welded shut. Prior to this, the machining station’s robot takes a surface sample from the capsule before it moves to the welding station to detect any potential contamination.
When the welded fuel capsule arrives for machining, its temperature and precise dimensions are inspected. This data is transferred to the MeteCNC® G-18-24-05, which machines the capsule within these specified limits. The machining process takes approximately four hours and includes six different stages. The entire process is fully automated from start to finish, including the vacuum extraction of milled chips.
A successful outcome is reflected in the capsule’s perfectly smooth surface, which allows for precise measurement of the weld quality and ensures the capsule moves seamlessly forward in the final disposal process.

High-Precision Machining for the Nuclear Industry: Robotised Machining Centre for Posiva Oy
Metecno Oy has designed, manufactured and installed a robotic machining station at Posiva Oy’s spent nuclear fuel encapsulation plant. The machining station consists of a custom-built, robot-operated CNC-controlled machining centre that ensures the dimensions and surface quality of the fuel capsules to be disposed of in ONKALO®.
The MeteCNC® special purpose machine grinds out any unevenness left in the capsule during welding, after which the station performs an inspection on the dimensions and surface quality of the capsule. The robot handles other auxiliary tasks in the process, such as handling NDT measuring devices and vacuuming milled chips. In practice, the machining station performs an important step in the capsule disposal process, as only capsules with a completely defect-free surface can be lowered into ONKALO®.
