Canada expands CANDU reactors, highlighting helium‑3 uses and latent weapons potential

The Canadian government unveiled a strategy to add ten new CANDU nuclear reactors, aiming to boost domestic energy capacity, strengthen the supply chain for Canadian‑made reactor technology and export it abroad. The plan emphasizes the reactors' by‑product helium‑3, a rare element seen as critical for the emerging quantum‑computing sector, and frames nuclear power as a driver of economic growth, energy transition and national sovereignty.

Analysts note that Canada’s extensive civilian nuclear infrastructure – large uranium reserves, longstanding CANDU expertise and expanding reactor projects – gives the country latent capability to develop nuclear weapons, although it lacks key facilities such as domestic uranium enrichment and plutonium separation and would face significant political and diplomatic costs before any weapons program could be realized.
