Fuel Assembly Shaker Test for Determining Loads on a PWR Assembly under Surrogate Normal Conditions of Truck Transport R0.1

The United States current approach of long-term storage at its nuclear power plants and independent spent fuel storage installation, and deferred transportation of used nuclear fuel (UNF), along with the trend of nuclear power plants using reactor fuel for a longer time, creates questions concerning the ability of this aged, high-burnup fuel to withstand stresses and strains seen during normal conditions of transport from its current location to a future consolidated storage facility or permanent repository.  UNFD R&D conducted testing employing surrogate instrumented rods (non-high-burnup) in a 17 x 17 pressurized water reactor (PWR) fuel assembly to capture the response to the loadings that would be experienced during normal conditions of transport along a 700-mile truck journey; results indicate that strain- or stress-based failure of fuel rods during normal transport seems unlikely.  Performance of high-burnup fuels in transport continues to be assessed.
