Description
Technical field
The present invention relates to the cement grout technique for fixing field of the middle low-level waste of nuclear industry, and in particular to a kind of solid body
The processing system and its method of medium formula homogenization.
Background technology
Nuclear power plant, Application of Nuclear Technology or military project can all produce a certain amount of radioactive solid waste, reflectivity waste according to
Different standards, is divided into variety classes, is divided into by level of activity's difference：Waste, low-level radioactive waste, reclaimed water is exempted to keep flat
Injectivity waste and high-level radwaste.With the fast development of nuclear energy, the yield and accumulation of radwaste are also therewith
Increase, now, the disposal for radwaste turn into the major issue that nuclear power development faces, if can not take these wastes
Effective measures are disposed, then environment caused by radwaste and human safety issues will increasingly protrude, while can also hinder
The sound development of nuclear industry.
In the prior art, for low-level radioactive waste and the grouting technique for fixing of middle level radioactive waste, China
Patent CN201510647008.1 discloses a kind of low middle zoom level radioactivity filter element processing method of nuclear power station and system,
Filter core processing method includes：S1, will change lower filter element be transported to it is temporary between it is temporary hydrophobic；S2, finish hydrophobic

Cross super compressor and temporary steel drum is compressed into a barrel cake；S4, the height and radioactive dosage for measuring bucket cake, and will based on measured value
Bucket cake optimization is loaded into shielding packing container；S5, fixed and capping processing of being in the milk is carried out to shielding packing container；S6, to screen
Packing container is covered to be conserved and radiological measuring；S7, will shielding packing container be sent into temporary library keep in.Realize and filter core is entered
The efficient volume reduction of row, waste inclusion product is reduced, reduce the technique effect of Waste disposal cost.
In addition, Chinese patent CN201410334521.0 discloses a kind of low middle Intermediate Level Radioactive activated carbon processing of nuclear power station
Method, it comprises the following steps：1) low middle Intermediate Level Radioactive activated carbon is collected, and is transported in activated charcoal measure tank；2)
Activated carbon in activated charcoal measure tank is dehydrated；3) activated carbon after dehydration is discharged into pail for used dressings；4) to equipped with activity
The pail for used dressings of charcoal carries out grouting and fixes and cover；5) conserve and keep in the pail for used dressings for being fixed with activated carbon.Compared with prior art,
The low middle Intermediate Level Radioactive activated carbon processing method of nuclear power station of the present invention using dehydration, metering, barrelling, fixation of being in the milk technique to work
Property charcoal handled, efficiently solve firming body radioactive level skewness, security risk present in prior art it is big,
The problems such as operating cost is high.
