Influence of thermal and radiation effects on microstructural and mechanical properties of Nb–1Zr

Non-uniform fuel distribution and thermo-mechanical analysis of a 1 MW thermal power micronuclear heat pipe reactor

“…5 that the monolith, made of Nb-1Zr, is at ∼20 K higher temperature than the heat pipe wall. Nb-1Zr is a refractory material with a high melting temperature of ∼2700 K [ 26 ] and is known for high temperature applications that can withstand high thermal stresses [ 27 ]. Thus, the monolith is also well within its safe temperature limit for structural integrity.…”
