McMaster Nuclear Reactor (MNR) operates under a Non-Power Reactor operating license issued by the Canadian Nuclear Safety Commission. Communication with our community is a key part of our operation. The MNR public disclosure policy is below. In addition to the MNR, we also have a Radioisotope production facility at the McMaster University Cyclotron Facility (MUCF).  This facility also operates under CNSC license and has a public disclosure protocol (Please click MUCF Public Disclosure for a PDF of the policy). MNR and the MUCF use a public disclosure protocol to relate information to the public on the issues relevant to licensed activities in the facility including: health and safety, security, environmental impacts and issues related to the lifecycle of the facility.


For more information on the MNR public disclosure protocol please read the following PDF.
