温度检验是秦山辐照监督试验一个组成部分,在监督管内放置温度盒,用以监测和判断辐照试样在反应堆运行时曾经达到的最高温度,给出监督试样的温度是否超过预计温度的证据。监督试样的过热使其辐照损伤量减少,其减少幅度与材料成分、组织结构及过热时间有关。过热温度信息提醒数据使用者进一步评估监督管的辐照温度史。 秦山第三根辐照监督管内装有4组温度盒,每个温度盒内装有5种不同熔点的测温合金,根据测温合金的熔化个数以及熔化状态来判断监督管曾经达到的最高温度。对测温合金的检测结果表明;第三根辐照监督管母材段内温度曾经达到291℃上,但低于297℃;焊缝段内温度曾达
The temperature test is an integral part of the Qinshan Irradiation Supervision Test. A temperature box is placed in the supervisory tube to monitor and determine the maximum temperature that the irradiated sample has reached during reactor operation, and whether the temperature of the supervised sample exceeds the expected temperature evidence. Supervising the sample to reduce its radiation damage caused by overheating of the sample, the extent of its reduction and material composition, structure and overheating time. Overheating temperature information alerts the data user to further evaluate the supervisory tube’s exposure temperature history. Qinshan Third Radiation Supervision tube equipped with four sets of temperature box, each temperature box contains five different melting temperature of the alloy, according to the temperature of the molten alloy melting number and state to determine the maximum temperature that has been reached . The test result of the temperature-controlled alloy showed that the temperature of the third root of the irradiation supervisory tube had reached 291 ℃ but lower than 297 ℃; the temperature in the weld zone had reached
