While the United States was celebrating Thanksgiving Day, Canada’s Nuclear Waste Management Organization (NWMO) announced that it has selected a site in northwestern Ontario for a deep geologic repository to hold the country’s spent nuclear fuel

NAC International announced that the Nuclear Regulatory Commission has certified a highly shielded version of the company’s OPTIMUS (Optimal Modular Universal Shipping) transportation package for radioactive materials and waste. NAC’s OPTIMUS-H is now approved under 10 CFR Part 71 with Certificate of Compliance (CoC) USA/9392/B(U)F-96, effective Aug. 5, 2024.

The OPTIMUS-H CoC follows licensing approvals of the cask in Canada and Australia. Previously, the lightweight version of the OPTIMUS package, OPTIMUS-L, received certification from the NRC and the Canadian Nuclear Safety Commission.

NAC unveiled its first OPTIMUS to the public at the 2020 Waste Management Conference in Phoenix. Since then, NAC has delivered 22 OPTIMUS-L and nine OPTIMUS-H systems to support North American packaging and transportation projects.

The Nuclear Regulatory Commission and Idaho National Laboratory are hosting a hybrid event on April 4 to launch a coordinated effort focused on leveraging consensus codes and standards to support deployment of new and advanced reactor technologies.

The meeting will be held from 9 a.m. to 5 p.m. (EDT) at the NRC’s Rockville, Md., headquarters and will be accessible online through Microsoft Teams. Participants must register to attend either in-person or virtually.

Through a trilateral agreement signed last week, nuclear regulatory agencies from the United States, Canada, and the United Kingdom will work together to expedite the licensing of advanced and small modular reactor technologies.

The Canadian Nuclear Safety Commission has decided to amend Canadian Nuclear Laboratories’ operating license for the Chalk River Laboratories, allowing the construction of a near surface disposal facility (NSDF) for low-level radioactive waste on the nuclear research site in Deep River, Ontario.

Bruce Power, operator of Ontario’s eight-unit Bruce nuclear plant, has notified Canadian regulators of its intent to launch an impact assessment (IA) for Bruce C—the company’s name for potential new nuclear generation at the site.

Westinghouse Electric Company welcomed 95 vendors to the Canadian Supplier Symposium last week to engage with current and potential suppliers for the company’s global new-build projects.

If we’re in a new nuclear renaissance, its capital would appear to be Ontario. On July 7, just two days after debuting a collaboration with Bruce Power to build up to 4.8 GW of new nuclear generation at the Bruce plant, the government of Ontario announced that it is working with Ontario Power Generation to begin planning and licensing for the deployment of three additional GE Hitachi Nuclear Energy (GEH) BWRX-300 small modular reactors at that utility’s Darlington site.

Westinghouse Electric Company has submitted to the Canadian Nuclear Safety Commission the first set of vendor design review (VDR) documents for its eVinci microreactor, the Pennsylvania-based nuclear technology firm announced yesterday. In September 2021, Westinghouse signed a service agreement with the CNSC that initiated the VDR.

The Nuclear Regulatory Commission and Poland’s National Atomic Energy Agency (PAA) have renewed their cooperation agreement for the next five years.

Ontario–based Terrestrial Energy announced yesterday that its U.S. branch has been awarded a regulatory assistance grant from the Department of Energy to support the company’s Nuclear Regulatory Commission licensing program for the Integral Molten Salt Reactor (IMSR) plant.

The Canadian Nuclear Safety Commission (CNSC) has completed phase two of its prelicensing vendor design review for Terrestrial Energy’s Integral Molten Salt Reactor (IMSR), the Ontario-based advanced nuclear technology firm announced Tuesday. Phase one of the VDR commenced in April 2016 and was completed in November of the following year.

The United States and Canadian nuclear industries used to be an example of how two independent teams of engineers facing an identical problem—making electricity from uranium—could come up with completely different answers. In the 1950s, Canada began designing a reactor with tubes, heavy water, and natural uranium, while in the U.S. it was big pots of light water and enriched uranium.

But 80 years later, there is a remarkable convergence. The North American push for a new generation of nuclear reactors, mostly small modular reactors (SMRs), is becoming binational, with U.S. and Canadian companies seeking markets and regulatory certification on both sides of the border and in many cases sourcing key components in the other country.

GE Hitachi Nuclear Energy’s (GEH’s) BWRX-300 technology has completed phases 1 and 2 of the Canadian Nuclear Safety Commission’s vendor design review (VDR) process, the Wilmington, N.C.–based company announced yesterday.

Westinghouse Electric Company has filed a notice of intent to submit key licensing reports for its eVinci microreactor to the Nuclear Regulatory Commission and Canadian Nuclear Safety Commission for joint review, the firm announced last week. (The two nuclear regulators signed a memorandum of cooperation in August 2019 to increase collaboration on the technical reviews of advanced reactor and small modular reactor technologies.)

The Canadian Nuclear Safety Commission (CNSC) and Poland’s National Atomic Energy Agency (PAA) have signed a memorandum of cooperation to share best practices and experience in reviewing advanced and small modular reactor technologies. (The two agencies are already engaged in cooperation on nuclear safety matters under a memorandum of understanding inked in 2014.)

Wilmington, N.C.–based GE Hitachi Nuclear Energy and Canadian firms Ontario Power Generation, SNC-Lavalin, and Aecon announced this morning the signing of a contract for the deployment of a BWRX-300 small modular reactor at OPG’s Darlington nuclear site in Canada. According to the announcement, it is the first commercial contract for a grid-scale SMR in North America.

The Canadian government last week released its 2022 Fall Economic Statement, featuring, among its many proposals, investment tax credits for a variety of clean energy technologies, including small modular reactors.

Ontario’s advanced nuclear technology firm Terrestrial Energy yesterday announced the signing of a letter of intent (LOI) with TerraPraxis, a U.K.-based nonprofit devoted to climate solutions, to cooperate on the latter’s Repowering Coal initiative—a program aimed at integrating clean heat sources with existing infrastructure at coal-fired power plants in North America and elsewhere.

Canada Infrastructure Bank (CIB) has finalized an agreement with Ontario Power Generation, committing C$970 million (about $715 million) to Canada’s first small modular reactor, to be located at OPG’s Darlington nuclear power plant in Clarington, Ontario.

A state-owned enterprise founded in 2017, CIB is charged with financially supporting revenue-generating infrastructure projects in the public interest via public-private partnerships. The agreement with OPG is the bank’s largest investment in clean power to date, according to a Tuesday joint announcement.
