“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.”

Session Organizer:
In this panel session, each panelist will discuss their country-specific approach to post-closure criticality safety in view of the final geological disposal of spent nuclear fuel and high-level radioactive waste. The discussion will include and reflect key topics presently being considered by the new international, waste management organization (WMO)-level collaboration initiative on post-closure criticality safety under the IGD-TP framework (https://igdtp.eu/). Each speaker will give a 10-minute summary with a Q&A afterwards.
