| 目的 对新燃料运输容器聚氨酯泡沫填充材料进行性能测试、寿命预测，验证其是否满足新燃料运输容器设计性能要求和使用寿命要求。方法 分别测试填充在新燃料运输容器不同区域的硬质聚氨酯泡沫的压缩性能、吸水性能、阻燃性能、隔热性能，并利用热重分析方法研究硬质聚氨酯泡沫填充材料的热老化性能，预测寿命。结果 根据测试结果，研制的硬质聚氨酯泡沫能够满足新燃料运输容器填充材料的设计性能要求和使用寿命要求，在最高正常使用温度38 ℃条件下，预测其寿命为34年。结论 在新燃料组件正常运输工况和事故运输工况条件下，硬质聚氨酯泡沫填充材料均能对燃料组件起到良好的保护作用，为实现新燃料运输容器国产化奠定了基础。 |
| 英文摘要: |
| The work aims to conduct performance test and life prediction on the polyurethane foam filled in new fuel transport cask, so as to verify whether it meets the requirements of design performance and lifetime of the new fuel transport cask. The compression performance, water absorption, flame retardation and thermal insulation of rigid polyurethane foam filled in different parts of the new fuel transport cask were respectively tested. The heat aging property of rigid polyurethane foam fillings was studied by means of thermogravimetric analysis to predict its lifetime. According to the test results, the rigid polyurethane foam developed could comply with the requirements of design performance and lifetime of the new fuel transport cask. It was predicted that the lifetime was 34 years at 38 ℃. Under the condition of normal and accident transportation, the rigid polyurethane foam fillings are capable of properly protecting the fuel assembly. It establishes foundation for the localization of manufacturing new fuel transport cask. |
