SUMMARY
The Coarse Mesh Radiation Transport (COMET) method is a radiation transport solver that has been used to solve whole core reactor eigenvalue and flux distribution problems. The method has been benchmarked against many different reactor types (e.g., PWR, BWR, HTGR, ABTR). A strength of the method is its formidable accuracy and computational efficiency: COMET solutions are computed to Monte Carlo accuracy in a runtime that is several orders of magnitude faster than stochastic calculations. However, with the growing ubiquity of parallel machines (e.g., gpu systems), serial implementations of COMET calculations will become less desirable, as parallel machines show more promise for maintaining and increasing computational efficiency in future applications. |
