Helical Fusion marks milestone in progress toward fusion power
Helical Fusion, a Japan-based fusion start-up that is developing a stellarator fusion power reactor, has announced it has successfully demonstrated its high-temperature superconducting (HTS) coil under relevant magnetic conditions.
A video highlighting the stellarator’s technology testing can be found here.

Lithium niobate plates intended for application as sensors for acoustical monitoring of nuclear reactors were subjected to thermal-neutron irradiation near room temperature. By 8 x 1019n/ cm2, a crystal had become highly disordered, as shown by the back-reflection Laue picture, by loss of piezoelectric response, and by loss of optical birefringence. This transformation appears to be a metamictization. Changes in optical absorption, tritium loss, postirradiation lithium migration, surface crazing, and effects of postirradiation storage at room temperature and of heating to 140°C are also observed.
