Technical Program for Long-Term Management of Canada’s Used Nuclear Fuel – Annual Report 2020

The technical objective of the APM approach is a Deep Geological Repository (DGR) that provides long-term isolation and containment, to ensure safety of people and the environment while the radioactivity in the used fuel decays. [...] The UFC decontamination cell removes potential contaminants from the outer surface of the UFC prior to the application of the copper coating to the UFC joint weld area. [...] It also demonstrated that the temperature of the surrounding rock is not significantly impacted by the presence of gaps in the container/buffer box, the buffer box/spacing gaps, and the fill/tunnel roof gaps. [...] 4.1 CONTAINER DURABILITY In 2020, the NWMO continued the execution of the Proof Test Program to validate the reference design of the Used Fuel Container (UFC) (shown in Figure 4-1 and Figure 4-2). [...] (a) (b) Note: The laser spot was positioned both to the right and to the top of the of the particle jet considering the dynamics of process.
