2017:12 Computational assessment of LOCA simulation tests on high burnup fuel rods in Halden and Studsvik
in a Light Water Reactor (LWR). The lack of cooling and the drop in pressure impose large stresses on the nuclear fuel which would increase the risk of fuel rod damage and the subsequent release of active ... 5 (see SSM report 2015:37). Objective This report describes the validation of the models against tests performed in Halden and in Studsvik, the latter commissioned by NRC. The objective for SSM in this...

2017:20 Assessment of inertia effects on transient clad-to-coolant heat transfer and coolant flow under reactivity initiated accidents
In this report, simple hydrodynamic models are used for studying the effects of coolant inertia on fuel-to-coolant heat transfer and coolant flow under reactivity initiated accidents in light water reactors ... SCANAIR fuel rod analysis program. The results of our study suggest that inertia has a negligible impact on the growth kinetics of the continuous vapour film that forms between the fuel rod cladding tube and...
