NEA irradiation system ready to deploy at MITR
A new irradiation experimental system is ready for deployment. The rig, which is the focus of In-Core Real-Time Mechanical Testing of Structural Materials (INCREASE-I), an OECD Nuclear Energy Agency project, will be used to conduct stress-relaxation tests of stainless steel at the Massachusetts Institute of Technology Reactor (MITR), according to the OECD NEA.

A new helical axis stellarator called Helias-Heliac Hybrid Stellarator(HHHS) is based on the modulated l = 1 helical coil. In order to obtain Helias-like and Heliac-like configurations, toroidal coils, poloidal coils and an additional l = 1 helical coil are adjusted to control magnetic field spectrum. It is shown that the bumpy field with opposite sign to l = 1 helical field is essential to minimize the neoclassical ripple transport. An HHHS configuration with sufficient magnetic well and reduced neoclassical ripple transport is demonstrated.
