Applications are now open for IAEA’s Marie Sklodowska-Curie Fellowship Programme to Push for More Women in Nuclear

The IAEA Marie Sklodowska-Curie Fellowship Programme (MSCFP) seeks to inspire and support young women to pursue a career in nuclear science and technology, nuclear safety and security, or non-proliferation. The application process has opened for female students interested in applying for a scholarship from the programme towards their Master’s degrees in nuclear science and technology, nuclear safety and security or non-proliferation.

Proton irradiation decelerates corrosion in structural materials from a molten salt reactor

Beam-facing side comparison regions of Ni-20Cr samples. Schematic of the irradiated (in orange) and unirradiated (in green). Zones and SEM images of the beam-facing side of the Ni-20Cr foils after 4 h at 650 °C at a beam current density of 2.5 μA/cm^2. Scale bar: 200 μm. Image adapted from Nat.Comm. 11 (2020) 3430.

Radiation nearly always deteriorates the materials exposed to it, requiring replacement of key components in high-radiation environments such as nuclear reactors. But for certain alloys that could be used in fission or fusion reactors, the opposite turns out to be true: Researchers from MIT and Lawrence Berkeley National Laboratory have now found that instead of hastening the material’s degradation, radiation actually improves its resistance, potentially doubling the material’s useful lifetime. This finding came as a surprise to nuclear scientists and can be potentially used in new fusion reactors designs. The work lead by Weiyue Zhou and Prof. Michael Short have been recently published in Nature Communications.

Assembly of ITER begins

First-of-a-kind components have been arriving in recent months at the ITER construction site in Cadarache, France, from the 35 ITER member countries around the world. The arrival on July 21 of the first sector of the ITER vacuum vessel from South Korea marked the beginning of a four-and-a-half year machine assembly process for the world’s largest tokamak, a magnetic fusion device designed to prove the feasibility of fusion as an energy source.

On July 28, technical and civil leaders from ITER member countries celebrated the beginning of assembly with a global event hosted virtually by French President Emmanuel Macron and livestreamed on YouTube.

Six Rings to Rule the ITER Plasma

Due to their exceptionally large dimensions, four of the six poloidal field coils that will be installed in the ITER machine cannot be produced off site and shipped, and therefore have to be manufactured in the Poloidal Field Coils Winding Facility, a factory set up on the ITER site in Caradache, France. Fusion for Energy (F4E), the European Domestic Agency, is in charge of procuring five of these magnets, and manages the Poloidal Field Coils Winding Facility and the contractors involved in their fabrication.
