[0002] Emergency facilities of nuclear power plants refer to facilities used for emergency response purposes, including main control room, auxiliary control room, emergency control center, technical support center, operation support center, etc. Habitability is used to describe whether an area meets the degree of continuous or temporary residence.

[0003] Relevant documents of nuclear power plants stipulate that nuclear power plant operators should take appropriate measures and provide sufficient information to protect the personnel in emergency facilities, prevent excessive exposure, release of radioactive materials, or secondary hazards such as explosive materials or toxic gases under accident conditions, so as to maintain their ability to take necessary actions. At the same time, nuclear power plant operators should evaluate the habitability of emergency facilities.

[0004] In the event of an accident, the dose exposure received by emergency personnel in emergency facilities mainly comes from external exposure to plumes and internal exposure through inhalation. At present, each nuclear power plant has given habitability judgment criteria based on the radiation monitoring instruments in emergency facilities represented by the emergency control center, but the readings of the radiation monitoring instruments can only judge external exposure and cannot evaluate the contribution of internal exposure pathways.

[0054] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0055] refer to Figure 1 , Figure 1 The present invention provides a flow chart of a method for determining the habitability of emergency facilities in a nuclear power plant. The method is implemented in the event of a nuclear accident.

[0056] Specifically, Figure 1 As shown, the method for determining the habitability of emergency facilities of a nuclear power plant includes the following steps:

[0057] Step S101: Obtain a selection instruction, and determine a habitability determination method for a nuclear power plant emergency facility according to the selection instruction.

[0058] Among them, the habitability determination methods include: any one or a combination of methods based on radiation monitoring, methods based on accident source items, and methods based on air sampling.

[0059] Specifically, when the habitability determination method adopts any one of the methods based on radiation monitoring, accident source terms, and air sampling, any one of step S102, step S103, and step S104 can be directly executed, and the specific step to be executed is determined according to the selected habitability determination method. If the habitability determination method adopts multiple combinations of the above three methods, after executing the habitability determination of any two combinations or three combinations of step S102, step S103, and step S104, step S105 needs to be executed. The specific implementation process is as follows: Figure 2 shown.

[0060] Step S102: If the habitability determination method is based on radiation monitoring, the habitability of the nuclear power plant emergency facilities is determined based on the first determination method, and a first habitability determination result and / or a first protective action recommendation is given.

[0061] In an embodiment of the present invention, if the habitability judgment method is based on radiation monitoring, the habitability of the nuclear power plant emergency facility is judged based on the first judgment method, and a first habitability judgment result and / or a first protective action recommendation are given, including: if the habitability judgment method is based on radiation monitoring, radiation monitoring data is obtained; based on the radiation monitoring data, the effective dose of personnel in the emergency facility during the continuous residence time is estimated to obtain a first dose estimation result; a judgment is made based on the first dose estimation result and the dose limit of habitability to obtain a first habitability judgment result; based on the first habitability judgment result, it is judged whether it is necessary to give a first protective action recommendation; if so, the first protective action recommendation is output based on the first dose estimation result; if not, it is not necessary to give a first protective action recommendation.

[0062] Specifically, the habitability determination based on radiation monitoring can refer to the following steps:

[0063] Step A1: Input radiation monitoring data. The radiation monitoring data includes data of each radiation monitoring instrument and handheld monitoring instrument in the emergency facility (generally taking the average data within a certain time period). The data of each radiation monitoring instrument and handheld monitoring instrument mainly refers to the radiation dose rate measured by these instruments, wherein the radiation dose rate refers to the irradiation dose per unit time, and the unit includes mSv / h, etc. These radiation monitoring data can be automatically acquired through the data interface module 105, or can be manually input by the operator / user. The present invention is not specifically limited.

[0064] Step A2: Dose estimation based on radiation monitoring data. Specifically, based on the maximum value of each radiation monitoring data and the integrity of the habitability system of the emergency facility, the effective dose of personnel in the emergency facility during the continuous residence time is estimated to obtain the first dose estimation result. The estimation method is as follows:

[0065] TED1=T·max(DR i ) / (1―F inh );

[0066]

[0067] in:

[0068] TED1 is the estimated effective dose, mSv;

[0069] T is the continuous residence time of personnel in the emergency facility, which is generally considered to be 30 days (720 hours);

[0070] DR is the reading of the radiation monitoring instrument (dose rate), mSv / h;

[0071] F inhis the internal radiation dose ratio, which is 0.15 when the habitability system is complete and 0.3 when the habitability system is incomplete;

[0072] I rs It is the integrity of the habitability system of the emergency facility (including the sum of ventilation and filtration systems, sealing measures, etc.), and its value is True (complete) or False (incomplete, i.e., fully or partially failed).

[0073] Step A3: Habitability judgment based on radiation monitoring. Based on the first dose estimation result and the dose limit for habitability, the judgment result of the habitability of the emergency facility is given; the specific judgment method is as follows:

[0074]

[0075] in:

[0076] TED limit The effective dose acceptance criterion for personnel (30 days) is 50 mSv;

[0077] RS1 is the habitability judgment result of the emergency facility based on radiation monitoring (i.e., the first habitability judgment result). The first habitability judgment result includes: habitability and non-residency. That is, when RS1 is True, the habitability judgment result is habitability; when RS1 is False, the habitability judgment result is non-residency;

[0078] TED1 is the estimated result of the first dose.

[0079] Step A4: Recommendations for protective actions based on radiation monitoring. When the habitability of the emergency facility is determined to be uninhabitable, recommendations for personnel shift times are given based on the first dose estimation results. The specific method is as follows:

[0080] T c1 =T·TED limit / TED.

[0081] Among them, T c1 Recommendations for the first protective action are recommendations for personnel shift changes.

[0082] Step S103: If the habitability judgment method is based on the accident source item, the habitability of the nuclear power plant emergency facilities is judged based on the second judgment method, and a second habitability judgment result and / or a second protective action recommendation are given.

[0083] In an embodiment of the present invention, if the habitability judgment method is a method based on accident source terms, the habitability of the nuclear power plant emergency facility is judged based on a second judgment method, and a second habitability judgment result and / or a second protective action recommendation are given, including: if the habitability judgment method is a method based on accident source terms, the dose prediction parameters of the accident source terms are obtained; based on the dose prediction parameters, the effective dose and thyroid dose of personnel in the emergency facility during the continuous residence time are estimated to obtain a second dose estimation result; a judgment is made based on the second dose estimation result and the dose limit of habitability to obtain a second habitability judgment result; based on the second habitability judgment result, it is judged whether a second protective action recommendation needs to be given; if so, the second protective action recommendation is output based on the second dose estimation result; if not, the second protective action recommendation does not need to be given.

[0084] Specifically, the habitability determination based on the accident source item can refer to the following steps:

[0085] Step B1: Input dose prediction parameters of the accident source item. Specifically, gradually input the unit release information (including: the location of the release source (unit), release height, release method and accident source item data (release amount of different radionuclides in different time periods)), meteorological data, emergency facility data, etc. Among them, the accident source item data and meteorological data in the unit release information can be automatically obtained through the data interface module 105.

[0086] The emergency facility data includes: the location information of the facilities in the nuclear emergency response, the habitability parameters of the emergency facilities (such as air purification capacity, protective shielding thickness, ventilation system, etc.), and the usable status of the emergency facilities. These data can be obtained in the following ways: Preset facility design data: the design parameters, location, ventilation equipment, air filtration system, protective shielding and other information of the facilities, which are usually fixed and stored in the database 100. These data can be called through the data management module 101 for calculation and judgment in the emergency response. Manual input by emergency personnel: If the data of the emergency facilities cannot be automatically collected, or some parameters need to be updated, the emergency personnel may manually input new facility information through the human-computer interaction module 106.

[0087] Step B2: Dose estimation is performed based on the dose prediction parameters of the accident source item. Specifically, the effective dose and thyroid dose of personnel in the emergency facility during the continuous residence time (30 days) are calculated and predicted. The specific calculation model and method can refer to the existing method, and the present invention does not make specific limitations.

[0088] Step B3: Determination of habitability based on accident source items. Specifically, based on the second dose estimation result and combined with the dose limit of habitability, the judgment result of the habitability of the emergency facility is given; the specific judgment method is as follows:

[0089]

[0090] in:

[0091] RS2 is the habitability judgment result of the emergency facility based on the accident source item (i.e., the second habitability judgment result), and its value is True (habitable) or False (unresidentable);

[0092] TED2 is the predicted effective dose (30 days), mSv;

[0093] THYD2 is the predicted thyroid dose (30 days), mSv;

[0094] TED limit The effective dose acceptance criterion for personnel (30 days) is 50 mSv;

[0095] THY limit Acceptance criteria for thyroid dose to personnel (30 days), 500 mSv;

[0096] TED2 and THYD2 are the estimated results of the second dose.

[0097] The second result of the residency determination includes: residency and non-residency. That is, when RS2 is True, the residency determination result is residency; when RS2 is False, the residency determination result is non-residency.

[0098] Step B4: Recommendations for protective actions based on accident source items. When the habitability judgment result of the emergency facility is not habitable, the time recommendations for personnel shifts are given based on the second dose prediction results. The specific method is as follows:

[0099] T c2 =T·min(TED limit / TED2,THYD limit / THYD2)

[0100] in:

[0101] T c2 Proposed shift times for personnel;

[0102] T is the continuous residence time of personnel in the emergency facility, which is generally considered to be 30 days (720 hours);

[0103] TED2 is the predicted effective dose (30 days), mSv;

[0104] THYD2 is the predicted thyroid dose (30 days), mSv;

[0105] THY limitAcceptance criteria for thyroid dose for personnel (30 days), 500 mSv.

[0106] Among them, T c2 Recommended as a second protective action.

[0107] Step S104: If the habitability determination method is based on air sampling, the habitability of the nuclear power plant emergency facilities is determined based on the third determination method, and a third habitability determination result and / or a third protective action recommendation is given.

[0108] In an embodiment of the present invention, if the habitability judgment method is based on air sampling, the habitability of the nuclear power plant emergency facility is judged based on a third judgment method, and a third habitability judgment result and / or a third protective action recommendation are given, including: if the habitability judgment method is based on air sampling, air sampling data is obtained; based on the air sampling data, the effective dose and thyroid dose of personnel in the emergency facility during the continuous residence time are estimated to obtain a third dose estimation result; a judgment is made based on the third dose estimation result and the dose limit of habitability to obtain a third habitability judgment result; based on the third habitability judgment result, it is judged whether a third protective action recommendation needs to be given; if so, a third protective action recommendation is output based on the third dose estimation result; if not, a third protective action recommendation does not need to be given.

[0109] Specifically, the habitability determination based on air sampling can refer to the following steps:

[0110] Step C1: Input air sampling data. Specifically, input the activity concentration data of each key nuclide of air sampling. Among them, the key nuclides include but are not limited to I-131, I-133, Cs-134, Cs-137, Te-132, Ru-106, I-135, etc.

[0111] Step C2: Dose estimation based on air sampling. Based on the activity concentration data of each key nuclide and the integrity of the habitability system of the emergency facility, estimate the effective dose and thyroid dose of personnel in the emergency facility during the continuous residence time (30 days). The estimation method is as follows:

[0112]

[0113] in:

[0114] BR is the breathing rate of personnel in the emergency facility, a constant, m 3 / s;

[0115] C i is the activity concentration of radionuclide i in the air, Bq / m 3 ;

[0116] DCF i,inh is the inhalation internal radiation dose conversion coefficient of radionuclide i, mSv / Bq;

[0117] DCF i,thyd is the thyroid dose conversion system for radionuclide i, mSv / Bq;

[0118] TED3 and THYD3 are the estimated results for the third dose.

[0119] Step C4: Determination of habitability based on air sampling: Based on the dose estimation results and the dose limit for habitability, the determination result of the habitability of the emergency facility is given; the specific determination method is as follows:

[0120]

[0121] in:

[0122] RS3 is the habitability judgment result of the emergency facility based on the accident source item (i.e., the second habitability judgment result), and its value is True (habitable) or False (unresidentable);

[0123] TED3 is the predicted effective dose (30 days), mSv;

[0124] THYD3 is the predicted thyroid dose (30 days), mSv;

[0125] TED limit The effective dose acceptance criterion for personnel (30 days) is 50 mSv;

[0126] THY limit Acceptance criteria for thyroid dose to personnel (30 days), 500 mSv;

[0127] TED3 and THYD3 are the estimated results for the third dose.

[0128] The third result of the residency determination includes: residency and non-residency. That is, when RS3 is True, the residency determination result is residency; when RS3 is False, the residency determination result is non-residency.

[0129] Step C5: Recommendations for protective actions based on air sampling. When the habitability of the emergency facility is determined to be uninhabitable, recommendations for personnel shift times are given based on the third dose estimation results. The specific method is as follows:

[0130] T c3 =T·min(TED limit / TED3,THYD limit / THYD3);

[0131] in:

[0132] T c3 is the recommended shift time for personnel; i.e. T c3 Recommended as a second protective action.

[0133] Step S105: If the habitability judgment method is a combination of a radiation monitoring-based method, an accident source-based method, and an air sampling-based method, then the target habitability judgment result and / or target protection action recommendation are output based on the habitability judgment results of the multiple combinations.

[0134] In an embodiment of the present invention, outputting a target habitability judgment result and / or a target protective action suggestion based on multiple combinations of habitability judgment results includes: if at least one judgment result among multiple combinations of habitability judgment results is not habitable, selecting the maximum value among multiple combinations of habitability judgment results as the target habitability judgment result, and selecting the minimum value among the protective action suggestions corresponding to the multiple combinations as the target protective action suggestion; if all judgment results among multiple combinations of habitability judgment results are habitable, outputting the values ​​of all dose estimation results. Here, the minimum value in the protective action suggestion is the minimum shift time of the personnel.

[0135] Specifically, if the residence determination method is any of the three determination methods, the residence determination results and protective action recommendations obtained by the aforementioned determination methods can be directly determined as the target residence determination results and target protective action recommendations, respectively.

[0136] If a combination of methods is used (i.e., the judgment method used is ≥ 2), the judgment result of the target habitability and the target protection action recommendations are determined according to the following methods:

[0137] a) When at least one habitability judgment result is not habitable, the maximum value of the predicted / estimated effective dose and thyroid dose is selected as the prediction result, and the minimum shift time is selected as the optimized protective action recommendation;

[0138] b) When all habitability judgments are positive, all predicted / estimated effective doses and thyroid doses are given as the basis for expert decision-making.

The habitability judgment module 102 based on radiation monitoring can directly interact with the human-computer interaction module 106 and the database 100, can call the data interface module 105, and can also be called by the protective action suggestion optimization module 107. For example, the user interacts with the habitability judgment module 102 based on radiation monitoring through the human-computer interaction module 106 to implement the habitability judgment based on radiation monitoring. For example, the habitability judgment module 102 based on radiation monitoring can access the dose prediction, habitability judgment and protective action suggestions and other related parameters stored in the database 100, and can also store the habitability judgment result output by the habitability judgment module 102 based on radiation monitoring in the database 100.
