Because the mechanical and thermal properties of materials can change substantially under neutron irradiation, one of the major challenges for the demonstration of fusion electricity is to develop neutron-resistant materials.

As part of the EUROfusion Roadmap to the Realisation of Fusion Energy (), the Belgian nuclear research lab SCK CEN tested �������ϲʸ��� baseline structural materials like tungsten, copper and steel during a lengthy regimen of high heat and intense neutron radiation flux. Inside SCK CEN's fission research reactor BR2, the material samples spent two years facing a temperature of up to 1200 degrees Celsius in a hail of neutrons from uranium fission.

SCK CEN will now partner with other European research labs to investigate how the high speed neutrons have impacted the thermo-mechanical properties of the irradiated samples.
