Abstract
Description
Technical Field
[0001] This invention relates to the field of smoke management technology, and in particular to a method, device and storage medium for assessing the impact of smoke on the main control room. Background Technology
[0002] As the core control unit for nuclear reactor operation, the main control room of a nuclear power plant bears the crucial responsibility of monitoring and managing the operational status of the entire nuclear reactor system. Its habitability during fire and smoke events—that is, whether the main control room can maintain a safe and suitable working environment in a fire or smoke environment—directly relates to the effectiveness of the nuclear safety defense-in-depth system. The nuclear safety defense-in-depth system is a multi-layered protective measure designed to ensure that the nuclear reactor remains in a safe state under various abnormal circumstances.
[0003] However, existing technologies often fail to adequately consider automatic protection measures for the main control room in the event of smoke hazards outside the electrical plant. In such cases, if smoke appears outside the electrical plant, operators inside the main control room may face obstructed vision and breathing difficulties, potentially leading to operational errors or an inability to respond promptly, thus impacting the safe operation of the nuclear reactor. Therefore, enhancing the automatic protection capabilities of the main control room in the event of fire and smoke incidents is a crucial element in ensuring the effectiveness of a nuclear safety defense-in-depth system. Summary of the Invention

[0015] The implementation of this invention has the following beneficial effects: This invention scientifically divides smoke event zones based on the locational relationship and functional planning between the smoke initiation point and the main control room. According to impact verification standards, the system design and procedural guidelines for different smoke event zones are verified, thereby quantifying the pollution risk of smoke events in each zone to the main control room and backup locations. This enables safety assessments of smoke events occurring in each zone, ultimately ensuring the safety of personnel within the plant. Attached Figure Description
[0016] The present invention will be further described below with reference to the accompanying drawings and embodiments: Figure 1 This is a flowchart of a method for assessing the impact of smoke on the control room in one embodiment. Detailed Implementation
[0017] To provide a clearer understanding of the technical features, objectives, and effects of the present invention, specific embodiments of the present invention will now be described in detail with reference to the accompanying drawings.
[0018] In the following description, specific details such as particular system architectures and techniques are set forth for illustrative purposes and not for limitation, in order to provide a thorough understanding of the embodiments of the invention. However, those skilled in the art will understand that the invention can be implemented in other embodiments without these specific details. In other instances, detailed descriptions of well-known systems, apparatuses, circuits, and methods are omitted so as not to obscure the description of the invention with unnecessary detail.
[0019] This invention provides a method for assessing the impact of smoke on the main control room. For example... Figure 1 As shown, it includes the following steps: Step S10: Based on the positional relationship between the smoke initiation points inside and outside the electrical plant and the main control room, as well as the functional planning of the smoke initiation points, divide the electrical plant into at least three smoke event zones.
[0020] Specifically, based on the locational relationship between the smoke origin point within the electrical plant and the main control room, as well as the functional planning and purpose of the area where the smoke origin point is located, and considering factors such as personnel evacuation and regional functions, the electrical plant will be divided into at least three independent smoke event zones. This will allow for more effective smoke monitoring and emergency response, ensuring that the smoke origin point can be quickly located and appropriate countermeasures can be taken in the event of a smoke incident, thereby maximizing the safety of the main control room and the normal operation of the reactor. Each zone will be equipped with corresponding monitoring equipment and emergency plans to ensure timely response and handling in the event of smoke.
[0021] In some scenarios, at least three smoke event zones are included: a main control room smoke event zone, an external electrical plant event zone, and an internal electrical plant event zone.
[0022] Step S20: Obtain the corresponding partitioning system design and partitioning procedure guide based on the smoke event partitioning.
[0023] To effectively respond to smog events, appropriate zoning system designs and zoning procedure guidelines should be obtained based on the specific circumstances of different areas. Different zoning system designs and zoning procedure guidelines provide different zoning guidance, enabling more targeted responses to smog events.
[0024] Step S30: Verify the partition system design and partition procedure guide according to the impact verification criteria, and obtain the verification results.
[0025] The design of a zoning system must comprehensively consider the equipment layout, ventilation system characteristics, and smoke diffusion paths within each zone to ensure that monitoring equipment can accurately capture smoke signals. Simultaneously, the zoning procedure guidelines should clearly define the emergency response procedures, personnel evacuation routes, and equipment operating specifications for each zone during smoke incidents. The zoning system design and zoning procedure guidelines should be validated according to impact verification standards to improve overall emergency response efficiency and safety.
[0026] Understandably, different smoke event zones correspond to different impact verification standards.
[0027] Step S40: Determine whether the verification results meet the main control room smoke evaluation criteria, and obtain the main control room smoke risk assessment results.
[0028] To determine whether the verification results meet the smoke assessment standards for the main control room, a comprehensive analysis and comparison of various indicators is conducted to ensure that each parameter reaches the preset safety threshold, thereby deriving the smoke risk assessment results for the main control room. By verifying key factors such as smoke concentration, diffusion rate, and duration, and considering the specific environment and equipment operating conditions of the main control room, the comprehensiveness and rigor of the assessment are ensured, guaranteeing the accuracy and reliability of the final risk assessment results.
[0029] This invention divides smoke event zones based on the locational relationship between the smoke initiation point and the main control room, as well as functional planning. Then, it verifies the zoning system design and zoning procedure guidelines for different smoke event zones according to impact verification standards. This quantifies the contamination risk of smoke events in different areas to the main control room and backup locations, assessing whether personnel safety can be guaranteed in the event of a smoke event in each zone, and ensuring, to the greatest extent possible, the reactor shutdown operation can be performed.
[0030] In some scenarios, smoke events are considered fire events.
[0031] In one embodiment, step S30 includes: Verify the evacuation path's accessibility when evacuating from a smoke event zone based on the zoning system design.
[0032] A key verification step in implementing a zoned evacuation system is ensuring that evacuation routes within each zone are unobstructed in the event of a smoke incident. Therefore, validating evacuation routes ensures the system can accommodate large numbers of people evacuating simultaneously in an emergency. Furthermore, regular drills and inspections of evacuation routes are necessary to ensure that all personnel can evacuate quickly and orderly during a real smoke incident, minimizing casualties and property damage.
[0033] Extract the operating procedure content from the procedure guide according to the impact verification criteria, and verify the operating procedure content.
[0034] Specifically, the procedure guide includes the execution path and steps for dealing with credible smoke events.
[0035] In some embodiments, electrical plant workers are trained in response to smoke incidents according to procedural guidelines.
[0036] In one embodiment, there are at least three smoke event zones, including a main control room smoke event zone, an external electrical plant event zone, a backup shutdown smoke event zone, and other smoke event zones within the electrical plant.
[0037] In some scenarios, the backup smoke event zone and other smoke event zones in the electrical plant are both considered part of the electrical plant smoke event zone.
[0038] The smoke incident zone in the main control room includes the main control room.
[0039] Specifically, the main control room is the area where operators are concentrated, and it contains the reactor control panel.
[0040] The standby shutdown smoke event zone includes the area within the electrical building equipped with shutdown control devices.
[0041] The area within the electrical plant equipped with shutdown control devices is a separate physical space and is equipped with shutdown control devices.
[0042] Other smoke incident zones within the electrical plant include the electrical distribution room.
[0043] Furthermore, other smoke incident zones within the electrical plant also include other high-fire-risk areas.
[0044] The external event zone of the electrical plant includes the remaining plant area excluding the electrical plant.
[0045] In one embodiment, if the smoke event partition is the main control room smoke event partition, step S30 further includes: Obtain the list of devices inside the main control room.
[0046] Determine whether the smoke event zone in the main control room meets the impact verification criteria based on the device list.
[0047] In some embodiments, the impact verification criteria include: the main control room smoke event zone is equipped with smoke detection and processing devices.
[0048] The zoning system design and zoning procedure guidelines for the smoke event zone in the main control room are verified in accordance with the impact verification standards. This includes: obtaining a list of internal devices in the main control room; determining whether the list includes smoke detection and processing devices; if so, the verification is successful; if not, relevant personnel must be notified.
[0049] Furthermore, it also includes: Does the zoning procedure guide include response steps for the detection of smoke or fire in the main control room smoke event zone, as well as procedures for evacuating personnel to the backup smoke event zone and operating the shutdown control device?
[0050] In some scenarios, it can be verified through keyword recognition and semantic recognition.
[0051] In some embodiments, the impact verification criteria also include a device such as a self-contained breathing apparatus or an external air source in the smoke event zone of the main control room.
[0052] By equipping the main control room's smoke incident zone with self-contained breathing apparatus or external air supply devices, the safety of the smoke incident zone can be enhanced. Even during a smoke incident in the main control room, staff can maintain clear thinking and a good working state, thus responding more effectively to emergencies and ensuring the safe operation of the main control room.
[0053] In one embodiment, if the smoke event partition is a standby smoke event partition to be turned off; step S30 further includes: The possibility of smoke from the backup closed smoke event zone spreading to the main control room smoke event zone was verified using a fire dynamics simulator.
[0054] If there is a possibility that the smoke from the backup smoke event zone could spread to the main control room smoke event zone, the verification will fail; otherwise, the verification will pass.
[0055] In some embodiments, the impact verification criteria also include a device such as a self-contained breathing apparatus or an external air source in the backup smoke event zone.
[0056] By equipping the backup shutdown smoke event area with self-contained breathing apparatus or external gas supply devices, the safety of the nuclear reactor can be enhanced. Even if smoke events occur in both the main control room smoke event area and the backup shutdown smoke event area, personnel can maintain control of the reactor, thereby responding to emergencies more effectively and ensuring the safe operation of the reactor.
[0057] In some embodiments, based on the partitioning system design of the backup smoke event partition, it is determined whether a smoke event in the backup smoke event partition will propagate to the shared path of the backup smoke event partition and the main control room smoke event partition. If it will propagate, the verification fails; if it will not, the verification passes.
[0058] In some embodiments, the stationing operation steps for the main control room smoke event partition when a smoke event occurs in the standby smoke event partition are extracted from the partitioning procedure guide for the standby smoke event partition. If these steps are extracted, the verification passes; otherwise, the verification fails.
[0059] In one embodiment, if the smoke event zone is another smoke event zone within the electrical plant; step S30 further includes: The possibility of smoke from other smoke event zones in the electrical plant spreading to the main control room smoke event zone and the backup closed smoke event zone was verified using a fire dynamics simulator.
[0060] If the possibility exists, the verification fails; if it does not exist, the verification passes.
[0061] Furthermore, based on the fire protection design, fire compartmentation, and fire response actions of other smoke event zones within the electrical plant, the smoke diffusion in other smoke event zones within the electrical plant was simulated and verified using a fire dynamics simulator.
[0062] Detailed settings were implemented for various parameters, including but not limited to the location and intensity of the smoke source, the physical characteristics of the smoke, and the parameters of the ventilation system and building structure within the electrical workshop. These parameter settings ensured that the simulation results accurately reflected the actual situation. During the simulation, key data such as the smoke's diffusion path, diffusion speed, and the time it took to reach the main control room smoke event zone and the backup shutdown smoke event zone were recorded in real time within the electrical workshop. Based on the recorded data, the probability of smoke spreading to the main control room smoke event zone and the backup shutdown smoke event zone was analyzed, improving the accuracy of subsequent verification and judgment.
[0063] In some embodiments, the operating procedures within the fire compartment of another smoke event zone within the electrical plant and the stationing operating procedures for the main control room smoke event zone are extracted from the zoning procedure guidelines of other smoke event zones within the electrical plant. If the above steps are found, the verification passes; otherwise, the verification fails.
[0064] In one embodiment, if the smoke event zone is an external event zone of the electrical plant, step S30 further includes: Based on a fire dynamics simulator, key evaluation indicators for the spread of smoke events from the external event zone of the electrical plant to the fresh air inlet of the electrical plant are obtained.
[0065] Specifically, key evaluation indicators include visibility (OD / m) and CO concentration (ppm). Concentration (%), temperature (°C).
[0066] Determine whether the key evaluation indicators meet the standards for the residency of personnel.
[0067] In some scenarios, visibility is greater than or equal to 10 meters; CO concentration is less than or equal to 450 ppm. The concentration shall not exceed 0.5%.
[0068] Furthermore, the temperature is the temperature of the hot smoke layer, which is less than 180°C.
[0069] In one embodiment, step S30 further includes: Obtain the fire characteristics of the event zones outside the electrical plant.
[0070] This includes combustibles, combustion conditions, and combustion products present in the event zone outside the electrical plant.
[0071] Based on the fire characteristics and the spatial context of the event zoning outside the electrical plant, determine whether there are any sensitive smoke events that could affect the main control room; If it exists, then use a sensitive smoke event to replace the smoke event for simulation.
[0072] Specifically, the spatial context includes the spatial relationship between the external event zone of the electrical plant and the smoke event zone of the main control room, as well as climatic conditions. Climatic conditions include one or more of the following: wind direction, temperature, and humidity.
[0073] In some embodiments, the stationing operation steps for the main control room smoke event zone when a smoke event occurs in the external electrical plant event zone and a fire occurs in any area of the external electrical plant event zone affecting the main control room smoke event zone are extracted from the zoning procedure guide of the external electrical plant event zone. If the above steps are found, the verification passes; if not, the verification fails.
[0074] The impact of a fire in any area of the external event zone of the electrical plant on the smoke event zone of the main control room includes smoke composition, duration of impact, and degree of impact.
[0075] The composition of the smoke, the duration of its impact, and the extent of its impact were obtained based on the characteristics of the fire.
[0076] In one executable embodiment, the point of origin of the smoke is the location where the fire occurs.
[0077] Based on the relationship between the fire location and the main control room, the electrical workshop is divided into the main control room smoke event zone, the electrical workshop external event zone, the standby shutdown smoke event zone, and other smoke event zones inside the electrical workshop.
[0078] This document provides a guide to the partitioning system design and partitioning procedures for obtaining the main control room smoke event partition, the electrical plant external event partition, the backup shutdown smoke event partition, and other smoke event partitions within the electrical plant.
[0079] Determine whether the partition system design and partition procedure guidelines meet the requirements of the impact verification standard. If they do, the partition verification for the smoke event passes; otherwise, the partition verification for the smoke event fails.

[0081] 3.
