(Orano) submitted an application to the Canadian Nuclear Safety Commission (CNSC) to amend its uranium mine operating licence for the expansion of the JEB Tailings Management Facility (TMF) at the McClean Lake Operation (MLO) [1]. Orano is the operator of the MLO, which is located in the Athabasca Basin of northern Saskatchewan. This Commission Member Document (CMD) presents CNSC staff’s assessment, conclusions and recommendations in respect of Orano’s licence amendment application for the JEB TMF expansion. CNSC staff have evaluated Orano’s application and supporting documentation and determined that the tailings preparation process and the JEB TMF will continue to perform as expected and continue to meet regulatory requirements with respect to the protection of the receiving environment. CNSC staff have evaluated the licensee’s compliance with the requirements of the Nuclear Safety and Control Act, the General Nuclear Safety and Control Regulations, the Uranium Mines and Mills Regulations and other applicable Regulations. The current CNSC licence issued in 2017 authorizes Orano to operate the MLO for a 10-year term (July 1, 2017 to June 30, 2027) [2]. The licence was renewed following a public hearing held in La Ronge, Saskatchewan.
