Technical Program for Long-Term Management of Canada’s Used Nuclear Fuel – Annual Report 2022

The purpose of this assessment is to realign the design inputs to support the next major work packages associated with the 9 UFPP: support of the Impact Assessment and Licence to Prepare Site Applications; and the next phase of design for the UFPP. [...] The scope of the trial was to fill the first 6 m of the mock emplacement room (approximately half the length of the room). [...] The equipment travels into the emplacement room and places gap fill material in the space between the buffer boxes and the interior walls and ceiling of the mock emplacement room. [...] Additionally, given the height constraints of the room, the ability to get the gap fill material from the hopper to the screws on top was identified as a risk and a prototype was built and tested to verify the concept before building the real equipment. [...] Given the tight tolerances inside the emplacement room and the overall length of the mobile cart, the mobile cart travels on rails to ensure the GFM feed and vibration systems fit into the void between the buffer boxes and the interior surface of the mock emplacement room.
