Ultra Safe Nuclear, the company that would have built a small nuclear reactor at a Global First Power project in Chalk River, Ont., filed for Chapter 11 bankruptcy in a Delaware court on Tuesday. The company said it has approached lenders but failed to negotiate sufficient funding. (The Globe and Mail)

Talking point: The Chalk River project, a partnership between Global First Power and Ontario Power Generation, was meant to demonstrate Ultra Safe Nuclear’s micro modular reactor (MMR) technology, and is a key piece of Canada’s nuclear ambitions. MMR is a type of small modular reactor, which could provide emissions-free power in a cheaper, more flexible form than industrial-scale reactors do. The Chalk River project has met regulatory delays, however, and Ultra Safe Nuclear’s bankruptcy filing raises doubts about the project’s prospects.
