A replica of the trefoil fuel carriage used to test fuel pencils in the NRX reactor loops. The assembly consists of three, full length (495 mm), fuel pencils mounted in a jig that could be located in one of the loops to carry out various fuel and sheath performance experiments. The entire assembly, which was presented to F. Blackstein on his retirement from AECL, is mounted on a 71 cm by 4 cm wooden base.
