Metal Additive Manufacturing in nuclear applications

Nuclear components produced through AM

Additive manufacturing can bring new opportunities for nuclear, with the ability to print spare parts on demand and manufacture complex geometries in one piece. However, there are also many challenges, for example when it comes to licensing and manufacturing wear resistant materials that will fit the demands of the nuclear industry. At this seminar, we highlighted opportunities and discussed challenges.

Due to technological development and increased productivity, costs related to metal additive manufacturing have reduced, and various new industrial sectors are currently in process to study and adopt additive manufacturing in their manufacturing portfolio.

In nuclear energy sector, there are two clear drivers to do this: capability to manufacture very complex geometrics; and possibility to manufacture spare parts on demand. The operational lifetime of NPP is long, and availability and long lead times of obsolete spare parts can be an issue. In the extreme, this causes prolonged and costly downtimes for NPP´s. Therefore, additive manufacturing offers also an attractive alternative for spare part manufacturing. This seminar focuses on using metal additive manufacturing in nuclear energy sector and highlights the capabilities and current challenges in nuclear applications.

The target group for the seminar was persons working with with maintenance, material research and plant development in the nuclear sector and persons in the additive manufacturing industry that would like to meet with the nuclear industry. Part of the presentations can be downloaded below.
