Description
Technical field
The present invention relates to a kind of marine nuclear emergency radiation monitor based on circular cylindrical shape buoy, belong to nuclear emergency Radiation monitoring technical field.
Background technology
Nuclear power is clean as one, safety, the efficiently energy, is more and more subject to the attention of a lot of country of the world.China, in order to alleviate the situation of energy supply anxiety, restructures the use of energy, and reduces environmental pollution, builds nuclear power station from last century the eighties, and at present, existing 15 cover nuclear power generating sets are put into commercial operation.Although nuclear power station has reliable security, but yet there is the possibility that serious nuclear accident occurs, the U.S. three miles of islands (1979), USSR (Union of Soviet Socialist Republics) Chernobyl (1986) and Fukushima, Japan (2011) three serious nuclear accident are exactly reverse side illustration, and once serious radioactive release occurs nuclear power station, large area environmental pollution will be caused, and then negative effect is brought to country, local economic construction and social stability, also can bring serious threat to the health of the public.
According to the requirement of International Atomic Energy Agency (IAEA) and the regulations of country, nuclear power station should delimit a border circular areas as Emergency Planning Zone (EPZ), and carry out Emergency Preparedness work on request in EPZ.China's nuclear power station build seashore in mostly, and therefore, EPZ not only contains land part, also covers the sea around nuclear power station.
Once there is serious radioactive release accident in nuclear power station, country, local government and nuclear power owner need to start emergency response immediately, take various effective measures to reduce or the loss that brings of reduction accident and harm, Emergency radiological monitoring is exactly a wherein very important response activities.
Radioactive ray is that human body cannot perception, and post accident environment radiation level is also constantly change, only has and just can be measured by special instrument.In time, accurately understand grasp environmental situation, national, local and that nuclear power owner emergency command mechanism for implementing is correct decision commanding, the emergent strength of tissue are carried out to effective emergency response and taken action most important.Due to the restriction by condition, the technological means that current marine nuclear emergency Radiation monitoring strength has also can not meet needs.
At present, China's nuclear emergency Radiation monitoring strength participates in the technological means that the marine nuclear emergency Radiation monitoring of Nuclear Power Station accident uses, and mainly expatriate personnel and ship, carries radiation gauge monitoring of environmental gamma dose rate; Collect seawater by sampler, to laboratory, qualitative and quantitative analysis is carried out to γ nucleic.As, in March, 2011, after Fukushima, Japan nuclear power station generation major accident, China has carried out marine Emergency radiological monitoring with regard to adopting the method.But existing marine Radiation monitoring technology has the following disadvantages: (1) measuring method is incorrect, measurement data is caused to be forbidden.According to international and national standard, during measurement environment gamma dose rate, detector should apart from floor level 1 meter, response angle 4 π.Ship is measured, especially uses large vessel, the position (highly) of radiation gauge is far above 1 meter, adds hull, cabin interlayer and deck to the weakening of ray, all can cause the error of measurement data.With radioactive source to ship do experiment obtain screen layer weaken coefficient, not only difficulty is greatly, costly, and technically be also difficult to realize, therefore, prior art cannot accurate measurements ocean surface Environmental γ-Radiation level.(2) obtain result speed comparatively slow, do not adapt to the requirement of emergency.Obtaining gamma spectrum data in seawater, and then identify that nuclear power plant accident is discharged in the sea radioactive nuclide, is an important content of nuclear emergency Radiation monitoring, be also evaluate ocean be contaminted situation, understand the important evidence of accident conditions and reckoning accident source term.The basic demand of Emergency radiological monitoring is fast, in time, accurately.The method that prior art mainly takes seawater to sample delivers to land specialized laboratory analytical test, and the personnel that employ are many, program is complicated, consuming time longer, in the emergency response stage, obviously can not embody the feature of " urgency ".(3) Integration ofTechnology degree is poor, and Monitoring Data can not get timely fusion.Because prior art is in measurement environment gamma dose rate and acquisition seawater gamma spectrum data, respectively by different personnel in different places, different instrument and equipments is used to carry out, the measuring technique of this separate type, to the timely fusion application of Monitoring Data, technical support is provided to bring difficulty in time to emergency command mechanism.Existing marine Emergency radiological monitoring technology, in the biography report mode of data, can not meet requirement fast.(4) be difficult to accomplish to monitor continuously, uninterruptedly, sea pollution situation can not get timely reflection.Due to the factor such as flowing of the discharge of accident, aerocolloidal sedimentation and seawater, marine γ radiation level is in constantly change, and therefore, marine nuclear emergency Radiation monitoring is the same with land, needs continuously, uninterruptedly.Prior art implements marine nuclear emergency Radiation monitoring can only Timing measurement, and the time interval is longer, more impossiblely accomplishes in round-the-clock, the full-time continuous monitoring of whole emergency response stage.Send ship to be implemented impact that marine nuclear emergency Radiation monitoring also will be subject to meteorologic factor, when the sea situation ship in case of severe cannot go to sea, monitoring just cannot be carried out.(5) employ resource more, duty assurance difficulty is large.Sending ship to implement marine nuclear emergency Radiation monitoring needs the parties concerned on land and ship to provide condition, and the personnel of input, equipment, funds are more, and work of organization and coordination is complicated, and duty assurance difficulty is large.From contaminated area, personnel out and ship should carry out decontamination decontamination, the especially decontamination of ship by regulation, and not only workload is large, and difficulty is larger.The volume of ship is comparatively large, and cabin quantity is more, and general ship is difficult to the preventive measures reaching tight requirements, and decontamination work is very time-consuming, and program is also very complicated.(6) increase the weight of personnel psychology burden, be difficult to use in high pollution district.Send someone, send ship to implement marine nuclear emergency Radiation monitoring need to enter contaminated area, no matter be professional monitoring personnel, or the support personnel on ship, there is heavier psychological burden in capital, worry to be subject to irradiating to have an impact to health, and the existence of this psychological condition, can have a negative impact to monitoring.Long-time or the marine nuclear emergency Radiation monitoring of multiple exercise, also need to carry out health examination and dosimeter evaluation to related personnel, this respect work also needs to employ medical resource, and have certain technical complexity, especially to the monitoring of marine heavily polluted area, by the restriction that personnel's radioactive dose controls, prior art cannot be implemented.
