Canada is making big moves in nuclear power. First, several Indigenous groups in Ontario are partnering in a new nuclear reactor project, backed by $700 million in government loans, a historic step towards their economic involvement in major infrastructure. Simultaneously, the Canadian government is trying to speed up approvals for big national projects, including Arctic highways and a nuclear waste storage site, through a new law. Critics question the high costs of nuclear versus renewables and worry about fast-tracking without proper review. Meanwhile, in India, a billionaire is investing in nuclear power, and a Canadian company is trying to get its nuclear tech approved in the US to power AI. Globally, there's ongoing tension over Iran's nuclear inspections.

This explanation is simplified to help readers understand the story. It is not factual reporting and should be checked against the original source articles before being cited or shared.
