SUMMARY

The Coarse Mesh Radiation Transport (COMET) method is a radiation transport solver that has been used to solve whole core eigenvalue problems for various nuclear reactor designs. Currently COMET makes use of a pre-computed response library in order to generate fast and accurate results. In order to facilitate calculations where the reactor state changes with time, as in depletion and thermal hydraulic calculations, an on-the-fly method of response function generation would be beneficial. In this way the response library could be updated during the calculation to take into account changes in the reactor. To facilitate this on-the-fly capacity a new stochastic radiation physics code will be developed that is optimized to calculate responses. An investigation will also be performed into how and when responses can be updated to increase computational efficiency while maintaining accuracy.
