Detailed Description
Embodiments of the present disclosure are described in detail below, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to like or similar elements or elements having like or similar functions throughout. The embodiments described below by referring to the drawings are exemplary and intended for the purpose of explaining the present disclosure and are not to be construed as limiting the present disclosure.
The following describes a method, an apparatus and an electronic device for radiation partitioning of a pressurized water reactor nuclear power plant according to an embodiment of the present disclosure with reference to the accompanying drawings.
Fig. 1 is a schematic flow chart of a method for radiation partitioning of a pressurized water reactor nuclear power plant according to an embodiment of the disclosure.
The embodiment of the disclosure is exemplified by the fact that the radiation partitioning method of the pressurized water reactor nuclear power plant is configured in the radiation partitioning device of the pressurized water reactor nuclear power plant, and the radiation partitioning device of the pressurized water reactor nuclear power plant can be applied to any electronic equipment, so that the electronic equipment can realize the radiation partitioning function of the pressurized water reactor nuclear power plant.
As shown in fig. 1, the method for radiation zoning of a pressurized water reactor nuclear power plant may include the steps of:
and step 101, acquiring radiation source item information corresponding to each device in the pressurized water reactor nuclear power plant under the condition of operation period and/or operation condition change.
The operation conditions may include process parameters such as temperature, pressure, flow rate of the device, etc. The change of the operation condition can lead to the change of the information of the radiation source item corresponding to each device.
It will be appreciated that the different operating cycles may result in a change in the information of the radiation source item corresponding to each device due to variations in burnup depth, rate of damage to the enclosure, decay of the nuclide, etc.
Alternatively, the radiation source item information may include at least one of: photon sources corresponding to different photon energies are strong; and the activity concentration of a plurality of radionuclides.
And 102, updating the radiation dose rate of each monitoring point in the space model corresponding to the pressurized water reactor nuclear power plant according to the radiation source item information.
It will be appreciated that the radiation source item information within each device changes, as will the corresponding radiation dose rate at each monitoring point. Therefore, the radiation dose rate of each monitoring point is recalculated according to the new radiation source item information corresponding to each device, and the radiation dose rate of the monitoring point in the space model is updated under the condition that the radiation dose rate of the monitoring point is changed.
Alternatively, a monte carlo method, or a method of point-kernel integration, may be employed, and the radiation dose rate of each monitoring point may be determined according to the radiation source item information of each device, which is not limited in this disclosure.
The space model may be a model which has been constructed and which relates to equipment information in a nuclear power plant.
Alternatively, the spatial model may include: the relative position between the various devices, the geometry of each device, the radiation source item information corresponding to each device, the location of the monitoring points, the radiation dose rate of each monitoring point, and the radiation partition.
Optionally, the spatial model may further include a geometric dimension of each device, a material of each device, and the like, which is not limited in this disclosure.
It will be appreciated that the spatial model may clearly and visually display the radiation source item information corresponding to each device, the radiation dose rate for each monitoring point, and the radiation zone determined from the radiation dose rates for the monitoring points.
Optionally, the radiation partition of the areas within the limits of different radiation dose rates may be performed according to the radiation protection partition of the pressurized water reactor and the rules of relevant national regulations, standards, etc.
For example, a plant of a nuclear power plant may be divided into a non-limiting area, a supervisory area, and a control area. The control area can be divided into a normal working area, a discontinuous working area, a limited working area, an equipment area and a high radiation area. It will be appreciated that the different regions correspond to different ranges of radiation dose rates.
Optionally, in the present disclosure, different radiation in the spatial model may be partitioned, and color difference display may be performed, so that a worker may intuitively determine a range of radiation dose rates corresponding to a certain area through colors of different areas in the spatial model.
For example, the different radiation zones may be displayed in colors such as red, orange, yellow, or green, respectively, without limitation of the present disclosure.
And step 103, updating the radiation partition in the space model according to the updated radiation dose rate of each monitoring point.
It can be appreciated that if the updated radiation dose rate of the monitoring point is different from the range of the radiation partition corresponding to the previous radiation dose rate, the radiation partition in the space model needs to be updated, so that the staff can acquire the real-time radiation partition in the nuclear power plant from the space model.
For example, the radiation partition corresponding to the radiation dose rate before the update of the monitoring point a is a discontinuous working area, and the radiation partition corresponding to the updated radiation dose rate is a regular working area, so that the radiation partition where the monitoring point a is located needs to be updated in the space model.
It should be noted that the foregoing examples are merely illustrative, and are not intended to be limiting of the radiation dose rate of the monitoring points and the radiation zone in the embodiments of the present disclosure.
In the embodiment of the disclosure, firstly, under the condition of a running period and/or running condition change, radiation source item information corresponding to each device in a pressurized water reactor nuclear power plant is obtained, then, according to the radiation source item information, the radiation dose rate of each monitoring point in a space model corresponding to the pressurized water reactor nuclear power plant is updated, and finally, according to the updated radiation dose rate of each monitoring point, the radiation partition in the space model is updated. Therefore, under the condition that the information of the radiation source item changes, the radiation dose rate of the monitoring point is updated, and then the radiation partition in the space model is updated, so that the radiation partition can be intuitively displayed in the space model, and the radiation partition can be efficiently and dynamically updated.
Fig. 2 is a flow chart of another method for radiation partitioning of a pressurized water reactor nuclear power plant according to an embodiment of the present disclosure.
As shown in fig. 2, the method for radiation zoning of a pressurized water reactor nuclear power plant may include the steps of:
The volume parameter may be the volume of the coolant in the device or the volume of the device itself. The flow parameter may be a parameter of the coolant passing through the device.
It will be appreciated that the operating cycle, or operating conditions, will vary, as will the volume and flow parameters of the device. Thus, the operating cycle, and/or the operating conditions change, requiring the volume and flow parameters of the device to be retrieved.
Alternatively, the volume parameters and the flow parameters may be input into a radiation source item calculation model to determine radiation source item information for the device.
Alternatively, the volume parameter and the flow parameter may be calculated using a program to determine radiation source item information for the device.
And 203, updating the radiation dose rate of each monitoring point in the space model corresponding to the pressurized water reactor nuclear power plant according to the radiation source item information.
And step 204, updating the radiation partition in the space model according to the updated radiation dose rate of each monitoring point.
The specific implementation of step 203 and step 204 may refer to the detailed steps in other embodiments of the disclosure, and will not be described in detail herein.
In the embodiment of the disclosure, firstly, under the condition of a running period and/or running condition change, the volume parameter and the flow parameter of each device are obtained, then, according to the volume parameter and the flow parameter of each device, the radiation source item information corresponding to each device is determined, then, according to the radiation source item information, the radiation dose rate of each monitoring point in a space model corresponding to a pressurized water reactor nuclear power plant is updated, and finally, according to the updated radiation dose rate of each monitoring point, the radiation partition in the space model is updated. Therefore, under the condition of the operation period and/or the operation condition change, the radiation dose rate of the monitoring points is updated, and then the radiation partition in the space model is updated, so that the radiation partition can be intuitively displayed in the space model, and the radiation partition can be dynamically updated with high efficiency.
