高压加热器的热交换管束泄漏事故将影响到核电厂机组的安全运行。对高压加热器管束进行涡流检测可以有效地发现缺陷。结合高压加热器管柬的涡流检测结果,通过对高压加热器运行情况的分析,分析管束的降质机理,提出了解决该问题的防护建议。
High-pressure heater heat exchanger tube bundle leakage accident will affect the safe operation of nuclear power plant units. Eddy current testing of the high pressure heater tube bundle can effectively detect defects. Combined with the eddy current testing results of high-pressure heater, through the analysis of the operation of high-pressure heaters, analysis of the degradation mechanism of the tube bundle, put forward the protection recommendations to solve this problem.
