North American construction is back—smaller and faster—at OPG’s Darlington
“The nuclear renaissance is real here,” said Ontario Power Generation’s Subo Sinnathamby on May 8, one year to the day after OPG secured a final investment decision to build the first of four planned BWRX-300 reactors at its Darlington nuclear power plant, and shortly after the new reactor’s foundation was lifted into place. “We got our license to construct in April and our [final investment decision] in May, and we’ve been off to the races since.”

The tritium trick technique was used to build-up radiogenic helium inside stainless steel 12Cr18Ni10Ti (SS). A great quantity of defects with a mean diameter of 20 nm, most probably platelet-like bubbles with 3He atoms, was observed in 3He-containing samples. The mean density of these bubbles in SS samples containing ~75 appm of 3He is estimated to be 61020 m-3. Much larger helium bubbles were observed in SS after annealing the samples at T1170 K. Thermal release of radiogenic helium occurs at T>1500 K. The presence of 3He in structural materials causes the formation of an additional state for hydrogen sorption.
