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 desorption behavior of deuterium from molybdenum, Mo-0.001 mass %C, Mo-0.06-0.092 mass %B, tungsten and W-0.011 mass %C prepared with arc-melting in Ar-10%D2 was studied using a vacuum desorption method in the temperature range of 533–1152K. The diffusivity of deuterium measured for molybdenum was D=4.97x10−7 exp(−36.7kJ/mol/RT)m2s−1 and D=1.77x10−6 exp(−55.8kJ/mol/RT)m2s−1 for tungsten. The diffusivity of deuterium for both molybdenum and tungsten decreased with an addition of C and B. This decrease was considered due to the trap effect of carbide and boride. The trapping energy estimated was 54 kJ/mol for Mo-C and Mo-B and 82kJ/mol for W-C.
