This is a developing area in the nuclear industry involving large scale multiphysics computation.
For the past several years Argonne National Laboratory and Purdue University have been supported by the Department of Energy (DOE) and the Electric Power Research Institute (EPRI) to develop a next generation nuclear reactor simulator based on the commercial Computational Fluid Dynamics (CFD) code STAR-CD to solve the temperature/fluid field and the integral transport code DeCART to solve the Boltzmann Equation for the neutron flux distribution in the reactor core. Applications of the Numerical Nuclear Reactor (NNR) to practical Light Water Reactor problems has required more than 100 million mesh and tens of hours of computational time on Linux clusters for the solution of a single reactor state point.
Clearly computational efficiency must be improved. That will be quite a challenge.
