60 Years of U: Perspectives on resources, demand, and the evolving role of nuclear energy
Recent years have seen growing global interest in nuclear energy and rising confidence in the sector. For the first time since the early 2000s, there is renewed optimism about the industry’s future. This change is driven by several major factors: geopolitical developments that highlight the need for secure energy supplies, a stronger focus on resilient energy systems, national commitments to decarbonization, and rising demand for clean and reliable electricity.

In order to verify the integrity of the first wall (FW) of the International Thermonuclear Experimental Reactor (ITER) the fabricated Be/Cu mock-ups were tested at the TSEFEY, e-beam facility, in Efremov, Russia. The Be/Cu mock-ups were joined with CuCrZr for a heat sink material among the Cu alloys and 316L austenitic stainless steel (SS316L) tubes for a coolant and then, joined with Be tiles for an armor material. Hot Isostatic Pressing (HIP) was used as a manufacturing method at 1050 °C, 100 MPa for 2 hours for a Cu/SS joining and at 620 °C, 100 MPa for 2 hours for a Be/Cu joining. The high heat flux (HHF) tests were performed for two Be/Cu mock-ups with a 2.5 MW/m2 heat flux and 80 sec durations, which were determined from a preliminary analysis with ANSYS-11. The temperature results from the test showed a good agreement with the analysis results and the fatigue lifetime was evaluated from the strain analysis results.
