Description
Technical field
The present invention relates to radioactive liquid treatment of wastes produced technical field, specifically a kind of nuclear power station based on CECE methods contains
HTO processing method and processing device.
Background technology
After the PHWR nuclear power generating sets in China were built up from 2003, run nearly 15 years, its reactor moderator and cold
But the cumulative growth of the content of tritium considers to be equipped with detritiation device to higher level, the factory in agent.In addition, continental nucleus in China
Electric project is carrying out work in every, will have inland project granted in the near future.The objective condition in inland factory site is (as discharged
The Capacity Ratio Coastal Power Plant of receiving water body environment is small, and the discharge diluting condition of waste liquid is not so good as Binhai Generator Station) discharge to tritium proposes
Higher requirement.Therefore, under current shortage of water resources and the increasingly strict situation of environment protectment protection, waste liquid containing tritium is entered
The necessity of row processing gradually strengthens.
Protium has three kinds of isotopes i.e. protium, deuterium, tritium in nature, there is 1 proton, no neutron, abundance in H protium atomic nucleus
For 99.98 ﹪；D deuteriums (are called heavy hydrogen), there is 1 proton, 1 neutron, the ﹪ of abundance 0.016 in atomic nucleus；T tritiums (are called overweight
Hydrogen), there are 1 proton, 2 neutrons, the ﹪ of abundance 0.004 in atomic nucleus.Tritium is radioactive element, but due to the β decays of tritium
The electronics of high-speed mobile can be released, human body will not be penetrated, therefore only produce interior irradiation when human body sucks tritium can just endanger people
Body health, tritium can launch β rays and decay into helium 3, and half-life period is 12.5.
Light water reactor and PHWR can all produce tritium in the process of running, and the annual tritium yield of PHWR is higher than light water reactor, by
Expensive in heavy water to be reused, it is necessary to purify Posterior circle, this causes the tritium level in heavy water constantly to accumulate, and can reach
80Ci/kg(3×1012Bq/L) left and right, in order to ensure the safety of operation maintenance personnel, irradiation dose is reduced, general PHWR can all match somebody with somebody
Detritiation device is put, is used to purify the tritium in moderator and cooling agent after a certain time of operation.And the cooling agent of light water reactor is
Part recycles, and the radioactivity liquid effluent of discharge has taken away a part of tritium, in order to reduce the agent of operation maintenance personnel exposure
Measure, tritium concentration control is 1.5 × 10 in reactor coolant7Below Bq/L.Tritium in cooling agent and moderator is mainly with tritiated
The form of water (HTO/DTO) is present, and it is to be present in the form of suspending or dissolving in water that this, which is different from general pollutant, but
The structure of hydrone itself is changed.Because itself and water have identical physicochemical properties, routine techniques is difficult by it
Remove.With the enhancing of mankind's environmental consciousness, country has issued more strict nuclear facilities supervision standard, GB6249-2011《Core
Dynamics factory's environmental radiation regulation of protection》Define at the km of inland nuclear power station floss hole one that Total Beta Radioactivity does not surpass in receiving water body
1Bq/L is crossed, tritium concentration is no more than 100Bq/L limitation index, while proposes 7.5 × 10 to the year total release of tritium13Bq/a
Emission limit；And the total release of the PHWR tritium of 3000MW heap power is no more than 3.5 × 1014Bq/a emission limit.
GB14587-2011《Nuclear power plant's radioactivity liquid effluent draining technology requirement》Regulation, at total floss hole downstream 1km, receiving
3H concentration must not exceed 100Bq/L in water body.
At present, for the existing presurized water reactor technology path including PHWR and light water reactor, either three generations's heap-type
Or two generations added heap-type, to waste liquid containing tritium without relatively inexpensive processing method.Current only external part PHWR is equipped with
Expensive tritium cleaning device, it is less economical because its operation energy consumption is very high, fail to be used widely, with the light water reactor of heap power
The water that must be purified is big compared with PHWR, is handled using prior art, its economy is worse, and it is net that domestic and international light water reactor is not equipped with tritium
Makeup is put.By taking heavy water detritiation as an example, existing process mainly includes two parts：One be tritium inversion of phases process, tritium will be contained
Tritium (DTO) form of heavy water changes into gas DT forms.Different according to exchanged form and operating condition, the conversion process of tritium can divide
For vapor catalyzed exchange (VPCE), liquid-phase catalysis exchange (LPCE) and combined electrolysis catalysis exchange (CECE).Another process be containing
The separation concentration process of deuterium, tritium gas.Theoretically VPCE, LPCE and CECE technique can be used in detritiation in light-water.But
VPCE techniques have the shortcomings of reaction temperature is high, and high energy consumption, exchange efficiency is low, and backend gas separating treatment amount is big；And LPCE techniques
Smaller there is also separation factor although reaction temperature is low, than low, backend gas separating treatment amount is bigger etc. asks liquid gas flow rate
Topic.Relative, because tritium is easier to be enriched in liquid phase, CECE techniques catalysis exchange column function is tritium is turned from gas phase to liquid phase again
Change, along with concentration of the electrolytic process to tritium, therefore CECE separation factor is very high, and the poor tritium of top end out is exchanged from catalysis
The concentration of tritium is very low in hydrogen, can handle and be expelled directly out without the cryogenic rectification of rear end.Three kinds of technologies of Integrated comparative, CECE
Most advantage, the higher PHWR of tritium concentration is applicable not only to, is also applied for the low light water reactor of tritium concentration, although its energy consumption is earlier above
Two kinds of technologies are low, but its specific energy consumption is still very high, and which also limits the application of detritiation device industrially.
