微芯片传感器可耐受核反应堆辐射与高温
Ke Ji Ri Bao· 2025-11-03 01:13
据美国缅因大学官网10月30日报道,经过两年研发与测试,该校科研团队研制出一种新 型微芯片传感器,能够耐受下一代核反应堆堆芯的强辐射与极端高温环境。 目前,核电约占美国总发电量的20%,其安全运行离不开各类传感器实时监测。传感器 负责采集温度、反应堆功率、中子通量及管壁应变等重要参数。 新型传感器系统的核心是一种基于纳米技术的微芯片,不仅能在反应堆最严苛的环境中 稳定工作,还能实时传输运行数据,有助于工程师更快发现故障、降低维护成本。 随着新一代高温反应堆(包括微反应堆技术)的研发推进,同等核燃料可产出更多能 量,因为更高温度能带来更优的热效率。然而,现有商用传感器难以承受这类反应堆500℃ —1000℃的工作高温。此项技术突破正好填补了这一空白。 除了耐高温,研究团队还将传感器置于强核辐射环境中进行测试。测试期间,传感器持 续稳定运行,未出现明显性能衰减。 目前,团队正致力于提升传感器的耐辐射强度,并计划开展更长时间的测试。未来还将 开发无需电池、完全依靠无线信号供电与传输的无线传感技术,并模拟反应堆在更高辐射水 平下长期运行的真实场景。 【责任编辑:王少晨 】 研究团队表示,这是首款能在800℃高温反应堆 ...
