Proposed nuclear facility – Wheeler River Project
Denison Mines Corporation (Denison) is proposing to develop an in situ recovery uranium mining and processing operation – the Wheeler River project – located in the Athabasca Basin in Saskatchewan, approximately 600 kilometres north of the City of Saskatoon.
Specifically, Denison is proposing to develop an operation that would produce up to 5,400 tonnes of uranium oxide annually for 20 years.
Authorization from the Canadian Nuclear Safety Commission (CNSC) is required in the form of a licence issued under subsection 24(2) of the Nuclear Safety and Control Act (NSCA), in order for the proposed project to proceed. However, before the Commission can make an NSCA licensing decision on this proposal, CNSC staff must complete an environmental assessment (EA) under the Canadian Environmental Assessment Act, 2012 (CEAA 2012).
|Location:||Athabasca Basin, Saskatchewan|
|Licensee:||Denison Mines Corporation|
|Status:||Application under review|
