Embodiment 1
[0034] Such as figure 2 As shown, the measurement system for reducing the signal response time of a self-powered neutron detector includes a self-powered neutron detector (SPND), a weak current amplifier, an ADC circuit, a single-chip microcomputer, a dual-channel DAC and an amplifying circuit, which are connected in the above ways The self-powered neutron detector signal measurement system can realize the rapid response of the current signal to the change of the monitored core neutron flux. Concrete measurement mode of the present invention is:
[0035] Place a self-powered neutron detector (SPND) in the reactor core, producing a 10 -14 ~10 -5 A-level weak current signal, this weak current signal is input into the weak current amplifier through the double-shielded twin-core transmission cable by means of differential input, and the weak current amplifier amplifies the signal.
[0036] The current output by the weak current amplifier is transmitted to the ADC circuit for a...
Embodiment 2
[0040] The difference between this embodiment and Embodiment 1 is that this embodiment provides the detection process of the self-powered neutron detector when the neutron flux in the reactor core is stable.
[0041] figure 2 The measurement system for reducing the signal response time of a self-powered neutron detector includes a self-powered neutron detector (SPND), a weak current amplifier, an ADC circuit, a single-chip microcomputer, a dual-channel DAC and an amplifier circuit.
[0042] The self-powered neutron detector (SPND) is placed in the detection tunnel of the reactor core, and 10 -14 ~10 -5 A-level weak current signals are transmitted to the outside of the stack through a double-shielded two-core transmission cable and input to a weak current amplifier for preliminary amplification. After the current signal is amplified, it is input to the ADC circuit for analog-to-digital conversion, and the converted digital signal and the signal without analog-to-digital conv...
