Abstract This paper summarizes the results of experimental measurements recently made on heavy water moderated plutonium-thorium (Pu-Th) mixed-oxide fuel bundles in the ZED-2 critical facility of Canadian Nuclear Laboratories. Pu-Th fuel in pressure-tube Heavy water reactors can help extend nuclear energy resources by utilizing plutonium from spent fuel, and extracting the energy potential of thorium. The ZED-2 experiment was a series of substitution measurements, with (Pu,Th)O2 test fuel placed into vertical channels filled with air or heavy water in a reference lattice of very low-enriched uranium (LEU) fuel. Sensitivity to the test fuel was optimized by placement into positions of higher power. MCNP5 simulations of the fuel substitution series are within uncertainty of critical moderator height measurements. The precision of the substitution measurements can help support the validation of reactor physics codes for evaluation of reactivity coefficients in PT-HWRs with fuel that contains a mixture of thorium and plutonium oxides.

在 ZED-2 关键设施中通过替代实验对钚-钍燃料进行的最新测量

摘要 本文总结了最近在加拿大核实验室 ZED-2 关键设施中对重水慢化钍钍 (Pu-Th) 混合氧化物燃料束进行的实验测量结果。压力管重水反应堆中的 Pu-Th 燃料可以通过利用乏燃料中的钚和提取钍的能源潜力来帮助扩展核能资源。ZED-2 实验是一系列替代测量,将 (Pu,Th)O2 测试燃料放入充满空气或重水的垂直通道中,该通道位于极低浓缩铀 (LEU) 燃料的参考晶格中。通过放置到更高功率的位置来优化对测试燃料的敏感性。燃料替代系列的 MCNP5 模拟处于临界慢化剂高度测量的不确定性范围内。
