Coupling Interface for Physics-to-System Simulations
MetadataShow full item record
A new interfacial code was developed to couple the reactor physics code PARCS/AGREE to the systems level code MELCOR, with a goal of enabling state- of-art transient event analysis for high temperature gas reactor designs. Following the completion of this new code, it was then demonstrated by running two different coupled simulations, one of which was a transient event. The resultant code is capable of coupling spatial power profiles, point kinetics information and transient reactivity values from PARCS/AGREE to MELCOR by means of input/output file manipulation. The coupling demonstrations were between PBMR400 models that were designed to have an equivalent core region nodalization to that which was used in the OECD/NEA PBMR400 benchmark, thus allowing for comparisons. The accessible coupled simulation output results as extracted from MELCOR appeared to be overly generalized. Even so, the axial profiles from the coupled steady-state demonstration were in good agreement with the axial profiles of other OECD/NEA participants. Conversely, the coupled transient simulations showed a suspect, maximum average nodal component temperature rise of approximately 0.4K from a 3+$ reactivity insertion.
