Description

Neutron activation sample quick transmission devices

Technical field

The invention belongs to pile neutron activated sample transmission technology and radio isotope preparing technical field, specifically relate to A kind of and neutron activation sample quick transmission devices.

Background technology

It is using the thermal neutron activated of reactor and qualitative to specifying element to carry out in sample with the kernel analysis such as gamma ray spectrometer instrument It is in the prior art to determination of trace element in sample than more efficient and sensitive analysis method, in life with quantitative analysis The scientific research field extensive use such as science, environmentology, geology, materialogy, archaeology.

Sample for activation analysis is before entrance reactor irradiation, it is necessary to be cleaned between target processed, heat degasification, bag The strict processing such as dress sealing, and according to the physics and chemical property of sample, and the condition of required irradiation, such as irradiation when Between, neutron fluence rate, cooling medium etc., select aluminum barrel packaging and welded seal, or the sample of the non-metallic material such as selection polyamide Product box is packed, and the sample box for meeting reactor irradiation safety requirements is made（Target piece）, it is then fed into reactor irradiation.After irradiation Sample box is handled between being transferred to sample preparation, and the sample for being adapted to measurement is made, then is delivered between measurement using the cores such as gamma ray spectrometer point Analyzer device is analyzed.When having influence on the measurement of target species when the radioactive intensity of the impurity species in sample is high, then need Activated sample is cooled to after being adapted to measurement and measured again, the waste sample for completing to measure is stored between being transferred to reservation or revocation.

Sample for needing long period irradiation and nucleic long lifespan to be measured, target is produced with most of radio isotopes Part is the same, sample box can be sent into reactor irradiation and taking-up using manual method under shutdown state, and be put into pig and turn Move to appointed place and carry out sample treatment and measurement.And there was only the minute even sample of second-time for half-life period, particularly need Accurately define the sample of exposure time and/or neutron fluence, then need between target processed between irradiator, sample preparation, between measurement and Sample quickly transmission and on-line analysis device are established between temporary or even between reservation or revocation, is imitated with improving the transhipment of sample with measuring Rate, ensure that the target species in sample can be measured effectively.At present, online activated sample transmitting device (is commonly called as " running rabbit Device ") it is Pneumatic transmission equipment, sample box high speed transfer between each workspace is driven using malleation or negative pressure mode（One As be not less than 10m/s）.

Since the 1970s, China Engineering Physics Research Institute and China Atomic Energy Science Research Institute etc. are single in China Position, has all built easy rabbit on its reactor, complete sample between target processed or between sample preparation to reactor Transmitted in both directions, shifted to the sample box after reactor sample introduction, irradiation and manufactured testing sample between laboratory, be unsatisfactory for surveying Measure waste sample after transfer and the preservation of desired sample, measurement and the work such as abandon mainly by being accomplished manually, and these race rabbits The automaticity of device design is not high, some critical components such as commutator, irradiator, sample transceiver（Including injector and Receive sample device）Function can not meet the automatical and efficient transmission of sample and the requirement of on-line measurement, be embodied in：Commutator conduct The transport hub of sample transfer means, its function are the transfers for realizing sample between different operating area.But existing commutator Limited between the stroke of its cylinder piston and be difficult to be segmented accurate control, a commutator is at best able to sample being transmitted to Both direction, sample only could be realized to three and the transmission in above direction by multiple commutator series/parallels, this string/ And mode not only increases transmitting device number of components and the complexity of apparatus structure, and in order to ensure at a high speed（Such as 10m/s very To more speed）The required turning radius of the safety of sample box is transmitted, distance remote enough must be kept between two commutators, The required space of sample transfer means installation and sample delivery duct length are added, reduces the transfer efficiency of sample box. , can be to the personnel in relatively closed laboratory and cylinder can also continually produce stronger vibrations and noise in plant running Damaged with equipment；Irradiator is safety index requirement highest component in rabbit, and its bottom is arranged on reactor In active region, function is the Safety Irradiation for realizing sample in reactor.But existing irradiator only has the list of sample irradiation One function, generally require to be passed through irradiation tube and defeated sample of the dry hot-air to long-play under the conditions of high humidity environment in advance Pipe is dehumidified, and is difficult to discharge irradiator bottom（May）The condensed water of aggregation（Even comprising the not spoke in reactor water The heap water of Micro blazed-grating and sleeve pipe is likely to occur according to device）, deposit the dust being activated in atmosphere or sample box friction sleeve pipe The dry linting of inwall is adhered on sample box, so between contaminated samples or contaminated samples measurement pipe, sample preparation, the equipment such as sample buffer With the potential safety hazard of facility, also do not possess the online radiation dose monitoring of heap sample box, hovering cools down super agent outside heap active region Technology and the functions such as sample box are measured, the environment space that overdose sample box is passed through in the transmitting procedure of long range to it be present The potential safety hazard of radiation hazradial bundle is caused with staff；The sample transceiver of automation is that online efficiently sample transfer fills with analysis That puts must configure, and particularly particularly important in efficient process complex sample and larger sample batch, its function is in program Realize that multiple samples continuously enter heap irradiation and go out heap under control, activated sample receives, be temporary（Cooling）And/or to measurement pipe（Enter Row measurement）, between sample preparation（Handled）, irradiator（Irradiate again）Transfer.Existing injector is air-cylinder type structure, receives sample device only It is sleeve pipe of the ttom of pipe with lid or plug, the injection port that sample box is put into injector by staff one by one is simultaneously manually or pneumatic Push sample box to outlet, then be passed through compressed air or vacuumize by sample box be delivered to irradiator irradiated and will activation Sample box afterwards, which is transferred to, receives sample device, opens and receives sample device bottom cover taking-up activated sample and manually shift or handle, largely Operation link is required for staff's field conduct, the larger and frequent contact radioactive sample of labor intensity of staff be present Face the risk of more ionising radiation harm.And when the sample of the sample in face of some complicated components and some non-principal components, Correct irradiation and measurement scheme could be formulated simultaneously by generally requiring the operations such as repeated multiple times sample introduction, irradiation, cooling, measurement analysis Realize the accurate analysis measurement of sample.The general work efficiency of existing sample transceiver is relatively low, it is difficult to meets high automaticity Sample activation and the needs of analytical equipment Effec-tive Function.

Although domestic irradiation sample transmission technology has compared with much progress, existing neutron activation sample transfer means are generally Have that automaticity is relatively low, transport efficacy of the sample between different operating area is relatively low, the dose of radiation detection of activated sample And the transfer between some laboratories is mostly by being accomplished manually, the labor intensity of staff and lacked by the larger grade of irradiation dose Point, lack sample box and go out the sample box of radiation dose monitoring online during heap, overdose inactive area hovering cooling, mistake in heap Product are automatically transferred to send measurement, the irradiation of the low auto-returned of product in the same old way when being cooled to coincidence measurement requirement between keeping in back to automatically again in the same old way Device irradiates again, same sample discontinuous repetitive irradiation, waste sample are automatically transferred to and technology and its function such as abandon between reservation or revocation Automation, also do not possess and exclude irradiator bottom ponding to prevent contaminated samples box, and by sample and transmission and then contaminated samples The measure of transmission pipeline and sample treatment and measurement laboratory installations and facilities, it is more difficult to meet to multiple types sample, a variety of Online automatic, fast and accurately irradiation and measurement the transmission requirement of radiation parameter and particularly second-time short-lived nuclide.And Can realize sample between target processed, irradiator, between sample preparation, between measurement, it is temporary between, between reservation or revocation etc. between any two points of workspace Automatic transmission, and inactive area in heap can be implemented to the sample box of overdose and hovered more efficient, the automation journey of cooling Du Genggao, safer neutron activation sample quick transmission devices are there is not yet open report.
