Radiation and Reactor Analysis (RRA) Overview Khalid Elsakhawy Necsa–Wits workshop, Necsa visitors centre September 2015
OVERVIEW • RRA team is part of the Radiation and Reactor Theory group (RRT), • The team is specialized in areas such as: - Nuclear reactor physics, - Reactor thermal-hydraulics analysis, - Shielding Calculation, - Criticality Calculation, and - Source term estimation. • This expertise is combined with the use of state of the art computer codes to analyse issues of interest to our clients; - Reactor core analysis system OSCAR, - MCNP, ORIGN, - RELAP 5, COBRA-TF codes, …etc. 2
