| 中文摘要: |
| 堆芯中子注量率测量系统是30万千瓦核电厂监测系统的重要组成部分之一。该系统中的密封段要在工作温度不大于100 ℃、 设计压力为17.16 MPa条件下满足长期密封要求。根据Arrhenius定律及 《机械密封试验方法》， 计算出了保证密封段正常工作5 a不泄漏需在240 ℃条件下进行加速寿命试验所需的试验时间。同时还制定了密封段加速寿命试验方案并进行了加速寿命试验， 对试验测量参数进行了分析。分析结果表明密封段满足正常工作5 a不泄漏的要求。密封段加速寿命试验是密封段型式试验的重要步骤，还可作为其它密封设备加速寿命试验的参考。 |

| Incore instrumentation system is one of the important parts of 300,000 kW nuclear power station. Seal assembly of incore instrumentation system should keep working for long time without leakage under the condition of temperature up to 100 ℃ and design pressure of 17.16 MPa. In order to ensure seal assembly 5 years working time under its actual working condition, testing time of accelerated life test under 240 ℃ was calculated based on Arrhenius law and mechanical seal test method. Accelerated life test scheme was worked out; accelerated life test was carried out; and test parameters measured were analyzed. The result showed that seal assembly can work 5 years without leakage under its actual working condition. Seal assembly accelerated life test is an important step of seal assembly type test. The purpose was to provide reference for accelerated life test of other seal components. |
