The control rods and the control drums of the present application are structures on the reactor for adjusting the reactivity of the reactor core and ensuring the operation/shutdown of the reactor. Which relies on neutron absorbing materials to alter the neutron changes in the core. The structure of the control rods and the control drums can be found in the related art, and the detailed description of the present application is omitted.
The control rods generally have a rod-like structure, and reactivity is adjusted by being inserted into the core at different depths or being located at different heights of the core. The control drum is typically provided on a lateral beryllium reflective layer, with reactivity being adjusted by rotating its sub-absorbers toward or away from the core.
The integrated value described herein refers to the reactivity change introduced by moving a control rod a certain distance to a certain position of the core or rotating a control drum a certain angle to a certain position of the core. Of course, the measurement method or apparatus of the present application is equally applicable to measuring differential values of control rods and/or control drums. The differential value refers to the reactivity change caused by moving a control rod from different heights by a unit distance or the reactivity change caused by rotating a control drum from different positions by a unit angle.
By measuring the integral value or the differential value of the control rod and/or the control drum, a data base can be provided for loading, critical experiment, operation and the like of the reactor, so that the safety of the reactor is improved.
Referring to fig. 1 to 5, a method for measuring an integrated value of a control rod and/or a control drum according to an embodiment of the present application includes the steps of: detecting selection operation of a display interface, and selecting an object to be measured according to the result of the selection operation, wherein the object comprises at least one of a control rod or a control drum; detecting the control operation of the display interface, and controlling the object to move to a shutdown position according to the result of the control operation, wherein the shutdown position is the position of the control rod or the control drum in the reactor core when the reactor is shutdown; acquiring the counting rate of the process that the object moves to the shutdown position; and calculating the integral value according to the counting rate.
The method can be realized through terminal equipment with a user operation interface. The terminal device includes, for example, a computer, a tablet, or a mobile phone. The method can be realized by APP installed on the terminal equipment. The above method may be implemented by a processor. The user operation interface may display a virtual object to be measured and/or an operation, control mechanism for the user to perform an operation and/or view a measurement result, a history, and the like.
As shown in fig. 1, the above-described measuring method may perform a step S101 of selecting an object to be measured, based on user demand. The object to be measured includes at least one of a control rod or a control drum.
With reference to fig. 2(a) -2(c), different combinations between the control rods and the control drums can be selected based on user demands to flexibly select an object to be measured, or to measure a plurality of objects at the same time to improve work efficiency.
In some embodiments, selecting the object to be measured may include selecting at least one control rod. The control rods are used as measuring objects, and the integral value of the control rods is measured, namely the reactivity change introduced in the process that the control rods descend from a preset position to be inserted into the reactor core until the reactor core reaches a shutdown position is measured. Fig. 2(a) illustrates three control rods in total, however, this illustration does not limit the present application, and a plurality of control rods may be provided according to actual needs.
In some embodiments, selecting the object to be measured may include selecting at least one control drum. The control drum is used as a measuring object, and the integral value of the control drum is measured, namely the change of reactivity introduced in the process of measuring the rotation of the control drum from a preset position to the reactor core until the reactor core reaches a shutdown position. Fig. 2(b) illustrates three control drums in total, however, this illustration does not constitute a limitation of the present application, and a plurality of control drums may be provided according to actual requirements.
In some embodiments, selecting the object to be measured may include selecting at least one control rod and at least one control drum. The control rods and control drums may be combined arbitrarily to measure multiple objects simultaneously.
Further, in step S101, the selecting an object to be measured further includes: highlighting the selected control bar and/or control drum; and/or display selected control rods and control drums based on different colors and/or different brightness.
In conjunction with fig. 2(a) -2(c), the user can view the selected result through the user operation interface. So that the user checks whether the selection result meets the actual requirement of the user.
As shown in fig. 2(a), when the user desires to select the "control bar 1", the finally selected "control bar 1" is highlighted. In some embodiments, highlighting the font comprising "control bar 1" is highlighted, e.g., the font changes from black to a color with increased brightness. The highlighting also includes that the background of the contour in which the control bar 1 is located is highlighted, e.g. the background filling changes from white to colored. By highlighting the selected object, the user can be made aware of the selection result at a glance, so that the user can determine whether the selection result is correct.
As shown in fig. 2(b), when the user desires to select the "control drum 2", the "control drum 2" finally selected is highlighted. In some embodiments, highlighting the font comprising "control drum 2" is highlighted, e.g., the font changes from black to a color with increased brightness. The highlighting also includes that the background of the contour on which the control drum 2 is located is highlighted, e.g. the background filling changes from white to color.
When the user desires to select the control rods and the control drums simultaneously, the selected control rods and control drums may be highlighted, as shown in fig. 2 (c). Among them, the types of control rods are further classified, and the control rods include a safety rod, an adjusting rod, and a compensating rod. The types of the control drums, including the safety drum and the conditioning drum, can be further divided. The user may select the subdivided control rod or control drum type as desired. As shown in fig. 2(c), the user can select the safety bar 1 and the safety drum 2 as the measurement objects.
When the user desires to select "safety bar 1" and "safety drum 2", both may be displayed by different colors and/or different brightnesses. Color and/or brightness may refer to font as well as background. In fig. 2(c), "safety bar 1" and "safety drum 2" are shown by different background colors.
It will be appreciated that displaying the selected measurement object may also be achieved in other ways, for example the selected object may have an enlarged font. Or through a window superimposed on the current interface.
Further, in step S101, the detecting a selection operation of the display interface includes: a cursor signal falling within a preset area of a frame portion surrounding each object to be measured is detected.
As shown in fig. 2 to 4, the user operation interface displays a frame portion surrounding each object to be measured, and when the user selects an object to be measured, the user only needs to move the selection cursor to a desired frame portion and move the cursor to a preset area of the frame portion. The preset region may be any position of the frame portion, for example, a boundary line of the frame portion, an inside of the frame portion, a region on the left of the frame portion, a region on the upper side of the frame portion, and the like. The user simply moves the cursor to select the desired object to be measured.
When the user operation interface is a touchable display screen, the user moves the cursor to a desired position by a finger. Further, after moving the cursor to a desired position, the user may perform a clicking operation with a finger to determine the object to be selected. Of course, the user may not perform the click operation.
When the user operation interface is a non-touch display screen, the user may move a cursor by means of, for example, a mouse, a remote control, or a pen. Further, after moving the cursor to a desired position, the user may perform a click operation.
Next, as shown in fig. 1, the above-described measuring method may perform step S103 of controlling the motion of the selected object.
Typically, the control rods and control drums are controlled in motion by a drive mechanism. The driving mechanism further comprises an electromagnetic mechanism, such as an electromagnet or an electromagnetic clutch, when the power supply of the electromagnetic mechanism is cut off, the control rod or the control drum is not acted by the driving mechanism and can move towards the reactor core under the action of self gravity or a spring mechanism. For example, when the drive mechanism or electromagnetic mechanism is de-energized, the control rods disengage from the drive mechanism and fall under their own weight until insertion into the core. When the driving mechanism or the electromagnetic mechanism is powered off, the control drum is driven by the released elastic potential energy to rotate towards the reactor core.
The power supply of the driving mechanism or the electromagnetic mechanism does not need to be manually cut off, and the measuring object can be controlled to move towards the reactor core by controlling the power supply of the driving mechanism or the electromagnetic mechanism to be turned off or cut off on the user operation interface.
As shown in fig. 4, the user operation interface may display an operation member representing a power source of the driving mechanism or the electromagnetic mechanism, and the operation member may include a button or a switch. By detecting the operation of the operating member, the measurement object can be made to start moving so as to measure its integrated value.
In some embodiments, detecting a control operation of the display interface includes: a signal detecting the number of times the button is clicked, or a signal detecting that a preset position of the switch is clicked.
When the operation member is a button, the user may click or click the button based on the selected object to turn off or cut off the power of the driving mechanism or the electromagnetic mechanism. For example, the power is turned off by clicking once, and the user only needs to perform one click operation.
When the operation member is a switch, the user may click or click a preset position of the switch based on the selected object, so that the power of the driving mechanism or the electromagnetic mechanism is turned off or cut off. For example, the switch is divided into two left and right areas, the left area representing "off" and the right area representing "on". The user can turn off the power supply by clicking the left area of the switch.
When the user operation interface is a touchable display screen, a user can click or click through fingers. When the user operation interface is a non-touch display screen, the user may perform a click or click operation by means of, for example, a mouse, a remote controller, or a pen.
The power supply of the drive mechanism or the electromagnetic mechanism of the corresponding control rod and/or control drum can be cut off through simple operation, so that the control rod and/or control drum moves towards the shutdown position, and reactivity change can be measured during the movement.
Further, with reference to fig. 3-4, the controlling the object to move to the shutdown position according to the result of the control operation in step S103 includes: and detecting a shutdown signal of a power supply of a drive mechanism of the control rod and/or the control drum, and determining the control rod and/or the control drum to move towards the shutdown position according to the shutdown signal.
After detecting the operation on the power button or switch of the drive mechanism or electromagnetic mechanism, it may be further detected whether the power of the drive mechanism or electromagnetic mechanism of the corresponding control rod and/or control drum is turned off, for example, when a turn-off signal of the power is detected, it may be determined that the corresponding control rod and/or control drum starts to move toward the shutdown position.
Through the detection steps, misoperation can be prevented, or the operation process can be determined conveniently, so that the experiment or test process is optimized.
Next, the above-described measuring method may perform the step S105 of acquiring the count rate during the movement of the selected object to the trip position.
The count rate may be measured, for example, by a detector disposed in the core.
Next, the above-described measuring method may perform step S107 of calculating an integrated value from the obtained count rate.
And calculating the reactivity according to the corresponding relation between the counting rate and the reactivity so as to obtain the integral value of the control rod and/or the control drum.
It should be noted that the time for moving the control rods and/or control drums to the shutdown position of the reactor according to the present application may satisfy the safety requirements of the reactor to ensure the safety and reliability of the experiment or test.
According to the method for measuring the integral value of the control rod and/or the control drum, the operation is simple, the working efficiency is high, the user can conveniently operate and/or watch the control rod and/or the control drum at any time through the display interface, and the user experience is improved.
