Reactor Core With A Plate-type Fuel Assembly

Abstract
The International Atomic Energy Agency (IAEA) organizes an International
Collaborative Standard Problem (ICSP) on \“Prediction of Hydro-Mechanical
Behaviour in Reactor Core with a Plate-type Fuel Assembly” and invites the
participation of interesting institutes from IAEA Member States. The
experimental study will be conducted in the Hydro-Mechanical Fuel Test
Facility in Oregon State University in the USA. The objective of the experiment
is to identify the flow conditions which induce the onset of elastic plate
deformation for fuel plate and to identify the flow conditions which produce
plate failure of each fuel plate material. This experimental data may be utilized to
assess multi-physics tools simulating the following phenomena: flow disparity
within a fuel plate assembly, bulk computational thermal hydraulic
characteristics, influence of pressure boundary condition on solid domain, and
fuel plate plastic deformation and vibration. The participants from IAEA
Member States will be able to use safety analysis codes and/or general
computational multi-physics codes to perform blind and open simulations of the
experiment. Through the ICSP, participants may identify any weaknesses or
strengths of their prediction tools, search a way to overcome any limitations, and
also suggest any further experiments or analytical models to fill the gap to be
identified in the ICSP.
Keywords: code validation, hydro-mechanical behaviour, ICSP, initial and
boundary conditions, plastic deformation, plate-type fuel assembly.
