Study on heat transfer to supercritical water in application to SMRs
The SuperSafe Reactor (SSR), a small modular reactor (SMR) concept with a supercritical water coolant, was subjected to a thermalhydraulic analysis and an economic analysis of its Levelized Unit of Energy Cost (LUEC). Heat transfer data was examined for the onset of deteriorated heat transfer using …

Exclusions Zones for Small Modular Reactors
… estimate the size of the exclusion zone around a small modular reactor (SMR). The aim of such zone is to provide an atmospheric space sufficient to dilute any radioactive releases during an accident, to a level below the safe regulated radiation dose for the public. A hypothetical severe accident …
