New consortium to address industry need for nuclear heat and power
Hoping to tackle a growing global demand for energy, The Open Group, a vendor-neutral technology and standards membership organization, has announced the formation of the Industrial Advanced Nuclear Consortium (IANC) to collaborate on finding advanced nuclear energy solutions to serve industrial customers.

The effects of internal tritium and helium on the tensile properties of two austenitic stainless steels and an iron-based superalloy have been studied. The materials tested were, forged 21Cr-6Ni-9Mn and 304L (tested in the annealed condition and two forged conditions), and a modified A-286 alloy. The accumulation of 3He from the radioactive decay of tritium caused an increase in the yield strength and a continuous decrease in the ductility in almost all materials tested. Increased 3He concentrations also caused a change in fracture mode from ductile rupture to predominantly intergranular fracture. The property changes resulted from 3He bubble-induced strengthening, which produced a change in deformation mode from long-range dislocation activity to deformation twinning. In the deformation-twinning mode, the 3He-accelerated fracture initiated at the intersections of deformation twins with grain boundaries. High-strength forged 304L was most resistant to 3He effects, owing to the redistribution of 3He on dislocations.
