The Great North: Canada begins the process of licensing a geologic repository
On January 5, the Nuclear Waste Management Organization (NWMO), the not-for-profit organization responsible for managing Canada’s nuclear waste, announced that it has submitted to the Canadian government an initial project description for its proposed deep geologic repository to hold Canada’s spent nuclear fuel.

Neutronics and photonics analysis for UWTOR-M was carried out to assess radiation streaming effects on reactor performance. The effect the lithium enrichment in the Li17Pb83 breeder has on radiation streaming was investigated. Using an enrichment of 35% was found to yield an adequate tritium breeding ratio of 1.08 and an overall energy multiplication of 1.153. The bulk shield was optimized to reduce the radiation effects in the superconducting magnets with the limited shielding space available in the design. Detailed analysis for the radiation streaming into the divertor regions has been performed. The divertor targets were found to recover 91% of the streaming energy.
