Problems solved by technology

.In this case, if the emergency-related system still adopts the traditional design idea, the system cost will not match its demand, which will cause waste of social resources and may also introduce unnecessary nuclear panic

Embodiment 1

[0032] Such as figure 1 As shown, an emergency radiation monitoring and notification system suitable for simplified emergency outside the high-temperature storage yard, which includes:

[0033] Monitoring terminal 1, which is set in the high temperature gas-cooled reactor nuclear power plant or in the near area outside the nuclear power plant, to monitor the radiation intensity in the high temperature gas-cooled reactor nuclear power plant or in the near area outside the nuclear power plant;

[0034] A processing server 2, which is arranged in the high temperature gas-cooled reactor nuclear power plant, is connected to the monitoring terminal 1, and receives and processes the monitoring signal of the monitoring terminal 1;

[0035] A decision server 3, which is connected to the processing server 2, receives the processed monitoring signal and issues a decision order;

[0036] Mobile terminal 4, it is connected with described processing server 2, receives the notification sign...

Embodiment 2

[0041] As described above, the emergency radiation monitoring and notification system suitable for emergency simplification outside the high-temperature stockyard, the difference of this embodiment is that the monitoring terminal 1 includes a fixed nuclear radiation monitor, which is installed in the nuclear power plant and / or Or in the vicinity of nuclear power plants to monitor the level of nuclear radiation. Due to its own advantages, the radiation level and radioactive pollution level around the high-temperature gas-cooled reactor are low, and the value changes little. It is difficult for the general simple nuclear radiation monitor to accurately monitor the specific value. The fixed nuclear radiation monitor is set on the ground and does not need to be moved. Therefore, high-precision instruments can be installed inside it, so that the detection accuracy of the nuclear radiation level and radioactive pollution level is high, and it can accurately identify the surrounding a...

Embodiment 3

[0057] Some production links of high-temperature gas-cooled reactors and accidents will release radionuclides to the surrounding environment, and radionuclides will release different rays, which will form external radiation to the human body. Radioactive aerosols are formed when radionuclides are absorbed by suspended matter in the atmosphere. Radioactive aerosols have a small aerodynamic diameter, are not easy to settle, and can be suspended in the air for a long time. Radioactive aerosols enter the human body mainly through human respiration and cause internal exposure to the human body. The radionuclides entering the human body are not easy to discharge. Even if the personnel leave the radiation area and environment, the radionuclides entering the body will still cause continuous radiation to the body (especially long-lived α radionuclides).

[0058] Therefore, as described above, the emergency radiation monitoring and notification system suitable for emergency simplificat...

Abstract

The invention discloses an emergency radiation monitoring and announcing system suitable for high-temperature reactor off-site emergency simplification. The system comprises a monitoring terminal which monitors the intensity of radiation around a high-temperature gas-cooled reactor, a processing server which is arranged near the high-temperature gas-cooled reactor and connected with the monitoring terminal and is used for receiving and processing a monitoring signal of the monitoring terminal, a decision server which is connected with the processing server and is used for receiving the processed monitoring signal and issuing a decision order, a mobile terminal which is connected with the processing server and is used for receiving a notification signal of the processing server, and an instruction terminal which is connected with the processing server and is used for receiving an instruction signal of the processing server and giving an instruction. Thus, only few monitoring terminals need to be set inside a nuclear power plant or in a near area outside a nuclear power plant, the monitoring scope is small, and the number of monitoring terminals used is small. The use cost of the whole system is reduced, and the whole emergency system is simple in structure and flexible in use.

Description

technical field [0001] The invention relates to the technical field of nuclear power plant emergency, in particular to an emergency radiation monitoring and notification system suitable for simplified emergency outside a high-temperature stockyard. Background technique [0002] High-temperature reactor, that is, high-temperature gas-cooled reactor, is a nuclear reactor with advanced technology, good safety, wide application and promising development prospects. It is mainly divided into high-temperature reactor with prismatic fuel elements and spherical fuel elements according to the structure of core fuel. High temperature stack. The high-temperature gas-cooled reactor adopts full-ceramic-coated granular fuel elements, an all-ceramic core structure design, and uses inert gas helium as the coolant to provide high-temperature helium. The reactor has good inherent safety, and the all-ceramic-coated granular fuel elements can still maintain good performance at high temperatures...
