Web31 de mai. de 2024 · However, the persistence of short- and long-lived fission products in these fuel cycles will limit their theoretical benefit for repository dimensions. HLW streams that predominately consist of fission products, typically conditioned into borosilicate glass, may require a repository up to 50% as large as a repository for LWR SNF ( 58 ). Web5 de jul. de 2016 · Although long-lived fission products such as 137 Cs and 90 Sr are detectable in Trinity nuclear debris today (9–14), these radionuclides have volatile precursors (e.g., 137 I and 137 Xe; Fig. 1) and are known to fractionate severely from Pu, making reliable interpretation difficult (5, 15). casty エキストラ 評判
