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 gamma-ray monitor installed at Processing Facility 1 in the JCO Tokai-works recorded the gamma dose rate change over time in proportion to power (nuclear fission rate) in the precipitation vessel from the beginning of the criticality accident to the end of the critical condition. The shape of the gamma dose rate record from 25 min after occurrence to the point of termination ("plateau" part) was normalized using the fission number 2.2 × 1018, and the absolute value of the power was evaluated.
