Expert Group on 3D Radiation Transport Benchmarks

The Expert Group deals with scientific issues in the field of deterministic and stochastic methods and computer codes relative to three dimensional radiation transport. Applications encompass transport through large and complex shields including void regions and highly heterogeneous reactor cores. Methods include discrete ordinates, nodal transport, finite elements with spherical harmonics, collision probabilities, Monte Carlo, etc. .

Objectives

• to develop benchmarks and comparison exercises for 3D radiation transport computer codes 
• to carry out validation of methods and identify their strength, limitations and accuracy 
• to suggest needs for method development 

Key Words

Sn, Monte Carlo, Radiation Transport
