The method of RPN3 Φ threshold value automation adjustment.
Background technique
(Φ is normal neutron gauges during shutdown to 3 Φ in RPN (Nuclear Instrumentation) Nuclear Instrument system
Digit rate) refer to that neutron flux height is alarmed during the range shutdown of source, it is one to the insertion depth of control rod and boron concentration dilution
Kind control means are reactor start and stop heaps in the process to the important means of reactivity control, and for prompting operations staff timely
Intervene reactor situation.According to the requirement of nuclear safety, its threshold value is adjusted.As shown in Figure 1,3 Φ definite values are adjusted,
Definite value is set as 2 Φ when downlink, adjustment when reaching 3 Φ；Definite value is set as 3 Φ when uplink, adjustment when reaching 2 Φ.For example, nuclear power
Φ=1500c/s when brand-name computer group downlink, then definite value should be set as 3000c/s, when continuing traveling downwardly to Φ=1000c/s, need again
3 Φ definite values are adjusted to 2000c/s, and so on, when uplink, is similar.
The specific implementation process of current 3 Φ adjusting thresholds judges set state by operations staff by artificially controlling, according to
The case where RPN Nuclear Instrument system counts rate, notice instrument control personnel enter the adjustment that scene cooperation carries out 3 Φ threshold values, 3 Φ threshold value tune
Whole manually completed by instrument control personnel, need to be entered and be carried out parameter modification inside safety level DCS Project Configuration, adjust frequency about 30
Secondary/each overhaul, there are following risks in the implementation process:
1,3 Φ adjusting thresholds are too high or too low, and will all violate running technology code requirement (influences unit subcritical state
It monitors and leads to false triggering of alarming)；
If 2, frequently adjustment fault will affect dress and reload work, delay the overhaul duration；
3, safety level DCS platform is frequently logged in, the modification of internal configuration parameter is carried out, if modification mistake will lead to equipment mistake
It is dynamic, it can lead to chaser when serious and jump heap；
4, the work runs execution with instrument control, there are human-equation error, links up the risk to fail；
5, the working time is uncertain high, about 30 times/each overhaul, daily to face that stop frequency also very high and most of
Start and stop is arranged in night, therefore adjustment need to also carry out at night, greatly increase human-equation error risk, and put into human cost mistake
It is high.
RPN Nuclear Instrument system realizes the function that reactor nucleus power is continuously measured and monitored, 3 Φ adjusting thresholds
Operations staff realizes with power plant instrument control personnel at present, and adjustment depends entirely on artificial judgement and operation, and needs instrument control
Personnel frequently enter safety level DCS configuration carry out parameter modification, it is desirable that time window it is stringent, the human cost of investment is excessively high,
The safe and stable operation of unit has been seriously affected, and has reduced the economic benefit of unit.
The information disclosed in the background technology section is intended only to increase the understanding to general background of the invention, without answering
When being considered as recognizing or imply that the information constitutes the prior art already known to those of ordinary skill in the art in any form.
