Tritium studies

In January 2007, the Commission directed Canadian Nuclear Safety Commission (CNSC) staff to initiate research studies on tritium releases in Canada and to study and evaluate tritium processing facilities exercising the best practices around the globe. In response, the CNSC has undertaken several research projects under the banner of the Tritium Studies Project. This research will enhance the information used in the regulatory oversight of tritium processing and tritium releases in Canada.

The following studies were conducted under the banner of the Tritium Studies Project:

CNSC open house: Tritium Studies Project

On April 28, 2010, CNSC hosted an open house in Ottawa for members of the public and stakeholders on the results of its Tritium Studies Project.

CNSC hosts tritium workshop to generate research ideas

From April 25 to 27, 2016, the Canadian Nuclear Safety Commission (CNSC) hosted a tritium workshop at the CNSC headquarters in Ottawa. This workshop brought together scientists from the CNSC, l’Institut de radioprotection et sûreté nucléaire (IRSN, France), Canadian Nuclear Laboratories and the University of Ottawa to discuss emerging topics in tritium research. The purpose of the workshop was to generate ideas to direct future CNSC research on tritium to expand on the body of work completed under the Tritium Studies Project.

Participants shared information on the various research projects underway and discussed research topics of mutual interest. The workshop concluded by identifying common research interests, based on uncertainties in past and current experimental research campaigns. The main areas identified for future investigations include:

  • obtaining representative samples in areas not influenced by nuclear facilities to better characterize background concentrations
  • investigating whether there are other forms of tritium in the environment (i.e., aerosols)
  • improving the methodology for sampling and analysing organically-bound tritium (OBT) in environmental samples (with a focus on soil), especially at low tritium concentrations

The workshop provided a unique opportunity for experts in tritium research to interact, explore research underway, discuss cutting-edge topics, and outline concrete mechanisms for future collaboration.
