The high-temperature gas cooled reactor is a fourth generation nuclear power plant with inherent safety characteristic and high thermal efficiency. Under normal operation conditions, the pressure of the secondary loop of the high-temperature gas cooled reactor is far higher than that of the primary loop, and if a heat transfer pipe of the steam generator leaks or breaks, water/steam in the steam generator enters the primary loop under the action of high pressure of the secondary side and flows through the reactor core along with helium.

Detailed Description
Exemplary embodiments of the present disclosure are described below with reference to the accompanying drawings, in which various details of the embodiments of the disclosure are included to assist understanding, and which are to be considered as merely exemplary. Accordingly, those of ordinary skill in the art will recognize that various changes and modifications of the embodiments described herein can be made without departing from the scope and spirit of the present disclosure. Also, descriptions of well-known functions and constructions are omitted in the following description for clarity and conciseness.
The method for early warning of the primary loop humidity of the high temperature gas cooled reactor provided by the present disclosure may be executed by the device for early warning of the primary loop humidity of the high temperature gas cooled reactor provided by the present disclosure, and may also be executed by the electronic device provided by the present disclosure, where the electronic device may include but is not limited to a desktop computer, a tablet computer, and other terminal devices, and the method for early warning of the primary loop humidity of the high temperature gas cooled reactor provided by the present disclosure is executed by the device for early warning of the primary loop humidity of the high temperature gas cooled reactor provided by the present disclosure, without limiting the present disclosure.
The method for early warning the primary circuit humidity of the high temperature gas cooled reactor provided by the present disclosure is described in detail below with reference to the accompanying drawings.
Fig. 1 is a schematic flow chart of a method for early warning of primary loop humidity of a high temperature gas cooled reactor according to an embodiment of the present disclosure.
As shown in fig. 1, the method for early warning the primary loop humidity of the high temperature gas cooled reactor may include the following steps:
Specifically, the device may read the display data of the loop humidity measuring device by reading the loop humidity data every day, for example, by selecting a fixed time of day.
It should be noted that the high temperature gas cooled reactor is designed with a primary loop humidity measuring device which can continuously monitor the primary loop humidity and output data as dew point, i.e. DP value, and humidity unit ppmv. Considering that the change of the equilibrium concentration value of impurities such as H2O in the helium of the primary circuit is small under the steady-state operation condition of the reactor, the display data of the primary circuit humidity measuring device is read to represent the daily humidity data at a fixed time every day, such as 20:00 every day.
And step 102, determining a reference time interval according to the time interval of the current date in the first quarter and historical maintenance data of the high-temperature gas-cooled reactor.
It should be noted that, every certain time, the nuclear power plant needs to be refueled and overhauled, for example, every 18 months. After a nuclear power plant overhaul, maintenance data in the process, such as a maintenance start time and a maintenance end time, may be recorded.
Given that there are four quarters of a year, each quarter comprising three months, the reference period can be further determined by analyzing the period of the current date in the quarter to which it belongs and historical maintenance data for the high temperature gas cooled reactor.
Wherein the humidity measurements for each date in the reference period may be used to determine the humidity reference value. The first quarter may be the quarter in which the current date is.
Alternatively, the apparatus may determine a previous quarter adjacent to the first quarter as the reference period in a case where a time interval between a second quarter to which the repair time in the historical repair data belongs and the first quarter is greater than or equal to one quarter.
For example, the repair time ends at 31 # 3 months, which is the first quarter of the year. Wherein the second quarter may be the quarter in which the maintenance time is located. If the current time is 8/6, the time interval between 3/31 has already satisfied a quarter, and thus the previous quarter of the quarter to which 8 months belongs may be used as a reference period, i.e., a period of time consisting of months 4, 5, and 6, which is not limited herein.
Or, in the case that the time interval between the second quarter to which the repair time in the historical repair data belongs and the first quarter is less than one quarter, and the period of the current date in the first quarter to which the repair time belongs is the first period, the reference period is determined to be the previous quarter adjacent to the first period.
Wherein the first period may be a period of time after the end of the repair of a specified length.
For example, the repair time ends at 31 # 3 months, which is the first quarter of the year. If the current time is month 4 and 6, the time interval between month 3 and month 31 is less than a quarter, so that the quarter before the maintenance can be used as a reference time period, i.e., a time period consisting of months 1, 2 and 3, which is not limited herein.
Or, in the case that the time interval between the second quarter and the first quarter to which the repair time in the historical repair data belongs is less than one quarter, and the period of the current date in the quarter to which the repair time belongs is not the first period, determining the reference period as at least one historical period in the season to which the reference period belongs.
For example, the repair time ends at 31 # 3 months, which is the first quarter of the year. If the current time is 5/6, which does not belong to the first time interval, the time interval between 3/31 is less than one quarter, so at least one historical time interval in the current season may be used as the reference time interval, for example, a time interval from 3/31 to 5/6 may be used as the reference time interval, or 4 months may also be used as the reference time interval, which is not limited herein.
It should be noted that if the time from the end of the last quarter to the shutdown is less than 3 months, that is, the data of three months cannot be obtained, the acquired data is used to calculate the humidity reference.
The temperature reference value may include a standard deviation and an arithmetic mean of humidity measurement values corresponding to the reference period. The arithmetic mean is also the reference mean.
It should be noted that after the reference period is determined, DP data, i.e., temperature measurements, may be obtained for each date in the reference period.
Specifically, the calculation of the reference average is to calculate the arithmetic average of the DP data in a reference period, and the calculation method is as follows, wherein x in the formulaiIs the DP data of day i, n is the number of DP data in a quarter:
μ＝(x1+x2+…+xn)/n
further, after the arithmetic mean is determined, the standard deviation can then be determined by the following formula:
wherein, x in the formulaiIs the DP data (humidity measurements) on day i, n is the number of DP data in a quarter, μ is the arithmetic mean, and σ is the standard deviation.
And 104, determining a deviation value according to the humidity measured value and the humidity reference value.
Alternatively, the deviation value may be determined based on a standard deviation and an arithmetic mean value included in the humidity measurement value and the humidity reference value.
Wherein the calculation formula of the deviation value of the daily humidity measurement value from the humidity reference value is as follows (in the formula, μ and σ are the arithmetic mean and standard deviation, respectively, of the humidity measurement values of the reference period):
Z＝(DP-μ)/σ
where DP is also the humidity measurement for the current date.
And 105, determining the current early warning strategy for the loop according to the deviation value.
Optionally, when the deviation value is greater than the preset threshold, determining the early warning policy of the loop as an execution response policy, where the response policy at least includes: checking the humidity measured value, sending a test prompt to an operator, and sampling and analyzing the impurity content of the primary loop coolant system.
Wherein, the preset threshold may be 3.
It should be noted that, if the deviation value is greater than the preset threshold, for example, greater than 3, it is indicated that the humidity data is 3 times higher than the reference average value, that is, it is indicated that the humidity data change trend meets the humidity change response trigger condition, the nuclear power station needs to immediately take a relevant response action until a humidity abnormal change reason is found or the humidity increase trend is recovered and eliminated.
Wherein, the response policy may be:
1. and immediately carrying out sampling analysis on the impurity content of the primary circuit coolant system, judging whether the impurity content exceeds a limit value specified by an operation technical specification, if the impurity content exceeds the operation limit value, responding according to a corresponding fault handling procedure of a power station, reading primary circuit humidity data at least every 8 hours, analyzing the data change trend, and increasing the humidity data reading frequency according to the situation.
2. And searching and analyzing the reason for the abnormal increase of the humidity of the primary circuit.
3. The loop humidity is reduced using a helium purge system.
4. And if necessary, executing normal shutdown operation to deal with the abnormal humidity increase fault.
5. And communicating with operators and the like to determine the correctness of the data and confirm whether the operation which can cause the humidity increase exists.
It should be noted that by analyzing the change trend of the humidity of the primary loop, the abnormal increase of the humidity of the primary loop in the impurity content sampling and analyzing interval of the primary loop coolant system can be effectively identified twice, and possible water inlet faults such as leakage of a heat transfer pipe of a steam generator and the like are found before the humidity reaches the emergency shutdown limit value, so that the unplanned shutdown is avoided, and the operation performance and the economic benefit of a power station are improved.
In the embodiment of the disclosure, a humidity measurement value of a high temperature gas cooled reactor loop on a current date is obtained, a reference time interval is determined according to a time interval of the current date in a first quarter and historical maintenance data of the high temperature gas cooled reactor, a humidity reference value in the reference time interval is obtained, a deviation value is determined according to the humidity measurement value and the humidity reference value, and a current early warning strategy for the loop is determined according to the deviation value. Therefore, the change trend of the humidity of the primary circuit can be analyzed according to the humidity reference value in the reference period and the temperature measurement value of each date in the reference period, so that the determined deviation value can be used as an alarm and protection trigger signal in time, possible water inlet faults such as steam generator heat transfer pipe leakage can be found before the humidity reaches the emergency shutdown limit value, unplanned shutdown is avoided, and the operation performance and economic benefit of a power station are improved.
Fig. 2 is a schematic flow chart of a method for early warning of primary loop humidity of a high temperature gas cooled reactor according to another embodiment of the present disclosure.
As shown in fig. 2, the method for early warning the primary loop humidity of the high temperature gas cooled reactor may include the following steps:
In step 203, humidity measurements are obtained for each date in the reference period.
It should be noted that, for specific implementation manners of steps 201, 202, and 203, reference may be made to the foregoing embodiments, which are not described herein again.
The arithmetic mean is also the reference mean.
Specifically, the calculation of the reference average is an arithmetic average of the humidity measurements over a reference time period, and is performed as follows, wherein x is in the formulaiIs the humidity measurement on day i, n is the number of days contained in the reference period:
μ＝(x1+x2+…+xn)/n
For example, the standard deviation can be determined by the following formula:
wherein, x in the formulaiIs the DP data (humidity measurements) on day i, n is the number of DP data in a quarter, μ is the arithmetic mean, and σ is the standard deviation.
In step 206, the arithmetic mean and the standard deviation are determined as humidity reference values within the reference period.
It should be noted that the temperature reference value may include a reference average value and a reference deviation value, that is, an arithmetic average value and a standard deviation, respectively.
And 208, determining the current early warning strategy for the loop according to the deviation value.
It should be noted that, reference may be made to the foregoing embodiments for specific implementation manners of steps 207 and 208, which are not described herein again.
