The in situ breeding and burning reactor (ISBBR), which makes use of the keracare twist and define cream outstanding breeding capability of metallic pellet and the excellent irradiation-resistant performance of SiCf/SiC ceramic composites cladding, can approach the design purpose of ultralong cycle and ultrahigh burnup and maintain stable radial po
Marine biogeochemical models have been widely used to understand ecosystem dynamics and biogeochemical cycles.To resolve more processes, models typically increase in complexity, and require optimization of more parameters.Data assimilation is an essential tool for parameter optimization, which can reduce model uncertainty and improve model predicta
