Confusion About a Second Repository for Radioactive Wastes.

From: Stop SMRs Canada , Thu, 18 Sept 2025

In June, the Nuclear Waste Management Organization (NWMO) posted a “discussion paper” outlining their intention to site a second deep geological repository (DGR) for radioactive waste.

The NWMO announcement of an additional DGR has caused confusion. MPs are having trouble keeping the story straight among the various nuclear waste schemes. Already constituents are receiving letters from MPs that clearly confuse the two, which puts MPs’ credibility on the line, as well further reducing public trust in the nuclear industry.

The latest NWMO DGR proposal is for a mix of “intermediate level” radioactive and – as an add on – high-level radioactive waste from future reactors.

The NWMO, a collaboration between the provincial utilities that generate and own the high-level nuclear fuel waste produced by nuclear reactors, has a mandate under the Nuclear Fuel Waste Act (2002) to develop an option to manage the highly-radioactive nuclear fuel waste long-term.

The NWMO’s June 2025 paper is purportedly premised on the “Integrated Strategy for Radioactive Waste” which they proposed to the federal government in 2023.

Making a careful distinction between government policy and industry strategy, the Minister of Natural Resources had acknowledged the nuclear industry’s proposed strategy for low and intermediate level wastes, framing the proposed strategy as one of “two fundamental recommendations” (the other related to low level wastes). The Minister summarized the plan thus: “Intermediate-level waste and non-fuel high-level waste will be disposed of in a deep geological repository with implementation by the NWMO.”

However, over the last 18 months the NWMO has increasingly been adding to the proposed DGR mix the high-level waste fuel waste from future small modular reactors and from the mega-reactors proposed for both the Bruce Nuclear Generating Station in southwestern Ontario and the Peace River area in Alberta.

The siting process for the DGR for high-level waste was extremely divisive and since the selection of the Revell site in northwestern Ontario in November 2024 there has been rising opposition and now a legal challenge from a nearby First Nation. The new DGR proposal promises more of the same divisiveness, opposition, and political pressures.
