Microstructural and thermophysical properties of U–6wt.%Zr alloy for fast reactor application

Ab Initio Enhanced calphad Modeling of Actinide-Rich Nuclear Fuels

“…14. The experimental data provided by Kaity et al [92] should be also questioned, since the measured heat capacity of U-14.3Zr in Fig. 14b is even higher than the one by Fedorov and Smirnov [103].…”

“…Only the occupied part between -4. [82,[85][86][87][88][89][90][91][92][93][94] and thermodynamic descriptions [77,79], (b) and (c) are magnified parts of (a). ........... 36 Figure 14.…”

“…Comparison of heat capacity of the U-Zr alloys between CALPHAD modelprediction [77,79] and experimental data [92][93][94]103]. (a) Summary of the experimental information provided by different research groups [92][93][94]103] [105], CALPHAD [77,79] and experimental data [44]. In CALPHAD modeling from the present work, case 1A is using the energy difference of (Zr) between hcp and δ structures as 1000 J/mol for model 1 (Zr)1(U,Zr)2, while case 1B is using 527.…”

“…Table 5, and the models used in different assessments [76][77][78][79][80][81] are given in Table 6. [82,[85][86][87][88][89][90][91][92][93][94] and thermodynamic descriptions [77,79], (b) and (c) are magnified parts of (a).…”

“…12, experimental information [81][82][83][84]92] of the phase boundary shows consistency only up to 50 at.% Zr. Furthermore, experimental data from Summers-Smith [82] and Kanno et al [84] show large discrepancies.…”
