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.”

Numerical models for simulating tritiated water (HTO) transport in unsaturated soil were developed to assess the migration of HTO from contaminated groundwater to terrestrial biosphere. Column experiments using sandy soil and deuterated water (D2O) were performed and a scenario of HTO transport from contaminated aquifer to atmosphere through an unsaturated soil zone was investigated. The results obtained by both model calculations and column experiments indicated that hydraulic conductivity of soil is an important soil parameter characterizing D2O transport speed and that dispersion and advection are dominant elemental transport processes in unsaturated soil.
