Latest Update

November 2, 2017 - Canadian Nuclear Laboratories has announced the decision to include only low-level radioactive waste in the Near Surface Disposal Facility, based on its consideration of federal, provincial and public comments. Read more in the Public Notice.

About the Proposal

The Near Surface Disposal Facility (NSDF) is a proposed engineered disposal facility for radioactive waste planned for the Chalk River Laboratories site (CRL). Canadian Nuclear Laboratories has provided a revised project description, allowing for the NSDF to also accept intermediate-leve waste, as opposed to solely low-level and mixed waste.  All waste to be disposed at the NSDF will be required to meet the waste acceptance criteria established to assure compliance with operational and long-term safety requirements.

The CRL site is located in Renfrew County, Ontario, on the shore of the Ottawa River, approximately 200 kilometres northwest of Ottawa. The site is situated within the boundaries of the Corporation of the Town of Deep River. 

The Near Surface Disposal Facility is planned to have an operating life of at least 50 years and as proposed, would be an engineered mound built at near-surface level on the CRL site. The engineered mound would be cellular, made up of multiple disposal cells consisting of:

  • base liner and final cover systems
  • leachate collection and leak detection systems
  • environmental monitoring systems

The proposed project would also include:

  • a wastewater treatment plant
  • supporting infrastructure, such as a truck wheel wash, vehicle monitoring and weighing stations, work stations and change facilities, security systems to monitor access and egress, construction trailers, and marine containers or tents for storage of construction materials

Under the Nuclear Safety and Control Act, CNL’s proposal requires approval by the Canadian Nuclear Safety Commission (CNSC) and involves an amendment to the Chalk River Laboratories (CRL) Nuclear Research and Test Establishment Operating Licence. An environmental assessment (EA) conducted under the Canadian Environmental Assessment Act, 2012 is required, and an EA decision affirming that the proposed activities will not cause significant adverse environmental effects, before the CNSC can make a licensing decision on this proposal.
