Description
Technical field
The present invention relates to the subsidiary technical field used in nuclear power station, be specifically related to a kind of interface measurer for radioactive wasted resin and measuring method thereof.
Background technology
In the prior art, employ a large amount of ion exchange resin make cleanser because nuclear power station and other many nuclear facilities are in operation, be used for removing the radioactive impurity of the band in water, to keep the purity of water.Thus the active spent resin of a large amount of band is created.Dealing carefully with these refuses, do not make environment be subject to nuclear pollution, is an important process in core field.According to national regulation, treatment scheme comprises conveying, store, be solidificated in interior links all will ensure absolute safety.
For storage, the water level in reply hold-up tank and amount of resin are monitored, and ensure that the water surface definitely floods lid resin face, and can not overflow outside tank.For solidification, the amount of resin in reply test tank accurately controls, and makes resin, water, the ratio of cement three meets design standards, so, be an important content in solidification process to the Survey control of amount of resin.But because this measuring technique difficulty is large, yet there are no both at home and abroad can effectively reliably to the Related product that resin boundary surface is measured.
Resin boundary surface measurement scheme is analyzed
Resin characteristics: density is 1.06, more bigger than water, good fluidity, the interface discrepancy in elevation are less.
Common measurement solid-liquid or the interfacial method of gas-solid have: ball float method, pressure application, reflectometry, Method of Dielectric Coefficient and transmission beam method.
Ball float method: because water differs very little with resin density, requires that ball float equivalent density accurately (1.03 is most suitable).In measuring process, in water, the normal dissolved impurity ratio of institute constantly changes, when density lower than 1 or higher than 1.06 time, then ball float can not be in solid-liquid interface place, causes the complete mistake of result.When water-mass density changes between 1-1.06, ball float is in solid-liquid interface place, but changes due to density, and ball float relative interface position also can change, and its change size is directly proportional to floating ball diameter.When water-mass density changes 1% (becoming 1.01 from 1), then there is the error of floating ball diameter 1/6th.Therefore there is the comparatively large even integrity problem of error in ball float method.
Pressure application: with ball float method, when water-mass density changes, there will be comparatively big error.
Reflectometry: light (ultrasound wave) is static to be on interface, launches a branch of pulsed light, light meets boundary reflection, is transmitted into the time difference between returning can converses interface distance by ranging pulse light.Or by height change, the change calculations of reflection angle goes out the change of interfacial level.Because resin particle is little, be reflected into diffuse reflection, reflection angle uncertain (reflection angle method is inapplicable), the intensity be reflected back very little (and fluctuation large, even receiving element place does not have light signal).So reflectometry reliability is lower.Ultrasonic probe can not be on the water surface in addition, otherwise most acoustical signal can be reflected in water surface place, if probe is in water, the sound wedge on ultrasonic transducer is engineering plastics, easily damages in radiation environment.
Method of Dielectric Coefficient: water and resin dielectric constant basically identical, and in water, dissolved impurity change can cause specific inductive capacity to have change greatly, therefore is that electric capacity or microwave wave speed measurement all can produce very big error.
Transmission beam method: the decay of ray in water and in resin is basically identical, therefore error is very large.
Therefore, be necessary to carry out necessary technological transformation to existing interface measurer for radioactive wasted resin and measuring method thereof.
