Applying uncertainty and sensitivity on thermal hydraulic subchannel analysis for the multi-application small light water reactor

Creator:

Brigantic, Adam

Abstract:

Small modular reactors (SMRs) are a recent advancement in commercial nuclear reactor design with growing interest worldwide. New SMR concepts, such as the Multi-Application Small Light Water Reactor (MASLWR), must undergo a licensing processes established by the U.S. Nuclear Regulatory Commission (NRC) prior to commercial operation. Given the lack of...

Investigation of the IRWST flow patterns during a simulated station blackout experiment on the OSU APEX facility

Creator:

Strohecker, Mark F.

Abstract:

The OSU/APEX thermal hydraulic test facility models the passive safety systems of the Westinghouse AP600 advanced light water reactor design. Numerous experiments have been performed to test these systems, the one of focus here is the station blackout scenario. This experiment simulated the complete loss of AC power to all...

Masters Thesis
An advanced nodal discretization for the quasi-diffusion low-order equations

Creator:

Nes, Razvan

Abstract:

The subject of this thesis is the development of a nodal discretization of the low-order quasi-diffusion (QDLO) equations for global reactor core calculations. The advantage of quasi-diffusion (QD) is that it is able to capture transport effects at the surface between unlike fuel assemblies better than the diffusion approximation. We...
