Whiteshell Laboratories
The Whiteshell Laboratories, originally known as the Whiteshell Nuclear Research Establishment (WNRE) was an Atomic Energy of Canada (AECL) laboratory in Manitoba, northeast of Winnipeg. It was originally built as a home for the experimental WR-1 reactor, but over time came to host a variety of experimental systems, including a SLOWPOKE reactor (the SLOWPOKE Demonstration Reactor) and the Underground Research Laboratory to study nuclear waste disposal. Employment peaked in the early 1970s at about 1,300, but during the 1980s the experiments began to wind down, and in 2003 the decision was made to close the site. the site is undergoing decommissioning with a planned completion date in 2024. The decommissioning process for WR-1 involves transporting low-level nuclear waste to another Canadian Nuclear Laboratories (CNL) research site, Chalk River Laboratories in Ottawa for containment, and encasing the reactor in concrete. The details of this process continue to be criticized, evaluated, and revised. Decommissioning has been delayed due to ongoing regulatory issues and safety concerns. Currently, 233 comments on the draft Environmental Impact (EI) Assessment have been filed by diverse stakeholders, covering concerns about impacts on the Winnipeg River, radiological inventory, grout, and concrete, assessing the potential impact of earthquakes, and the
