【摘要】 本文提出了第四代钍基熔盐堆(TMSR)的核测系统设计,包括整体结构设计、探测器选型、信号处理电子学及系统接口等。中子探测器出来的微弱信号被放大、甄别、预处理后送入保护系统,由数字化的保护系统实现数字采样和处理,其它系统所需要的中子注量率信息将由保护系统对外传输。更多还原

【Abstract】 The Design of the TMSR Ex-core Nuclear Instrumentation System is introduced, including the overall structure design, selection of detector and signal processing electronics and system interface. The structure and function of the TMSR Ex-core Nuclear Instrumentation System is simplified. The weak signal from Neutron detector is amplified discriminated, preprocessed, and sent into the protection system. Then the signal is digitized and processed by the digital protection system, and the digital protection system will transmit the neutron flux to the other control system.更多还原
