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.”

This paper summarizes an updated process for risk-informed surveillance frequency control program (RI-SFCP) implementation at the Fitzpatrick nuclear power station in the past two years. This paper covers the Fitzpatrick program of implementing industry initiative 5b RI-SFCPs for multiple Technical Specification controlled surveillances. This project includes selection and prioritization of specific target surveillance test interval extensions; and development, review, and implementation of surveillance test risk informed documented evaluation (STRIDE) packages designed to support extension of conventional surveillance requirement test intervals, in accordance with “Risk-Informed Technical Specifications Initiative 5b, Risk-Informed Method for Control of Surveillance Frequencies, Industry Guideline,” NEI 04-10, Revision 1 [1]. The scope of work associated with STRIDE development includes probabilistic risk assessment (PRA) case studies, deterministic assessment (DA) evaluations, and, where required, instrument drift evaluation (IDE). This paper outlines a framework and lessons learned for practical implementation of an RI-SFCP for Fitzpatrick within the context of an integrated risk-informed performance-based regulation application program with emphasis on instrumentation and control systems.
