Reactor irradiation pbte bi2te3 and znsb
WebAbstract. The alloys Nb-1Zr and PWC-11 (Nb-1Zr-0.1C) were selected as prime candidate alloys for the SP-100 reactor. Since the mechanical properties of niobium alloys irradiated to end-of-life exposure levels of about 2 x 10SW neutrons/mS (E > 0.1 MeV) at temperatures above 1300 K were not available, an irradiation experiment (B-350) in EBR-II was conducted. WebDespite this, existing thermoelectric modules, particularly for recovering low-grade but abundant heat of <600 K, have been limited to Bi 2 Te 3 alloys in both p- and n-type …
