June 23, 2014 — Last June, CASL launched its first Virtual Environment for Reactor Applications (VERA) Test Stand on the Westinghouse engineering computer cluster. Westinghouse selected the AP1000® pressurized water reactor (PWR) first core for the Test Stand simulation
University of Michigan adds Depletion Capability to MPACT for VERA-CS
June 23, 2014 — MPACT is a three-dimensional (3-D) whole core transport code being developed by the University of Michigan and ORNL for the CASL VERA toolset. MPACT’s integral transport solution is obtained by means of the method of characteristics (MOC)
Validation of Peregrine with Test Reactor Data

Lift Forces in Bubbly Flows
January 27, 2014 — The dynamics of two-phase (gas/liquid) bubbly flows are complex: bubbles deform and disperse; large latent heats and heat capacity differentials influence local boiling; and relatively small changes in heated surface temperatures yield order of magnitude changes in boiling complexity.
