Verification and application of SuperMC3.3 to lead-bismuth-cooled fast reactor

Abstract

Lead-cooled fast re ac tors have mul ti lay ered de signs and large in ter nal tem per a ture dif ferences, which cause chal lenges in sim u lat ing re ac tor phys ics. SuperMC, a large-scale in tegrated soft ware sys tem for neutronics de sign, is in her ently able to ad dress com plex ge om etries and multi-tem per a ture prob lems. The pur pose of this study is to ver ify the ap pli ca bil ity of SuperMC to the lead-bis muth-cooled fast re ac tor RBEC-M. The multi-tem per a ture cross-sec tion gen er a tion func tion of SuperMC was em ployed and showed good per for mance. Based on the ENDF/B-VII.1 li brary, the ef fec tive mul ti pli ca tion fac tor k eff ob tained by SuperMC showed good agree ment with those from pre vi ous works. The re la tion ship of k eff and 15 N en rich ment ap plied to the fuel ma te rial was also stud ied, with the re sults show ing that in creased 15 N could sig nif i cantly im prove k eff. The ax ial power pro file and ki net ics param e ters for the bench mark were then cal cu lated and an a lyzed. This work thus ver i fied the ap pli ca bil ity of SuperMC for com pre hen sive neutronics sim u la tions for lead-bis muth-cooled fast re ac tors.

Simultaneous Dynamic Optimization of Technical Indicators and Mining Sequence in Metal Mines Using Hybrid Coding AADE

“…Lagrangian relaxation methods are intelligent evolutionary methods that are mainly mixed coding genetic algorithms and mixed coding differential evolutionary algorithms. These methods have the advantages of global searching and robustness, and they have been used to solve mixed-integer optimization problems with good results [20], [25], [26].…”
