Eddy Current Testing of Nuclear Power Plant High-pressure Heater Tubes and Defect Mechanism Analysis
摘 要
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。结合高压加热器管束的涡流检测结果,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。
Abstract
Leaking failures of the heat-exchanging tubes of high-pressure heaters have serious impact on the safe operation of nuclear power plant. Eddy current testing for the high-pressure heaters can always find the defects effectively. In this thesis, with the results from eddy current testing, by analyzing the operation condition of high-pressure tubes, the degradation mechanism is studied and the protection suggestion is introduced.
