【摘要】 本试验研究的目的是评价RY-Ⅰ型乏燃料运输容器的热性能,它包括正常运输状态的传热性能及火灾事故时的耐火能力。确定了数学物理模型,并编制了RYTDOT-N、RYTDOT-F两个计算机程序。乏燃料运输容器热试验在中国是首次。试验是将原型容器放在加热炉内进行的。试验在超过按时间平均的环境温度820℃下持续30分钟,试验方法、试验条件和试验装置均满足IAEA的安全标准“放射性物质安全运输规程”的要求。试验结果证明了容器的耐火性能符合要求。试验的动态温度测量结果与程序计算结果吻合甚好,从而验证了程序的正确性。更多还原

【Abstract】 The purpose of this study is to evaluate the thermal performances of RY- I type transport cask for spent fuels. The performances are the heat transfer performance in normal transport condition and the fire resistance in fire accident. A mathematical and physical model has been built and two computer programs, RYTDOT-N and RYTDOT-F, have been completed for calculation. This was the first time in China to perform the thermal test for a transport cask. For testing the prototype cask, it was put into a furnace and the test lasted 30 minutes. During the test period the time-averaged environment temperature was greater than 820C. The test methods, conditions and instrumentation fully conformed to the requirement specified by IAEA "Regulations for the Safe Transport of Radioactive Material". Test results show that the fire resistivity of the cask has met the requirement. The dynamic temperature of the cask measured was in good agreement with the results calculated by computer program. It was also proving the correctness of computer program developed.更多还原
