>>183
Because abandoned ion-exchange resins are in-combustible, it's hard to usually burn-reduce the volume of those.
Accordingly, the volume of low-level abandoned resins are reduced by burning those resins together with miscellaneous wastes, and they are stored as uniform solid matters through cement-slugging in facilities or are disposed.
Meanwhile, most of high level abandoned resins are stored at half-processed in the tank of the facility.
The same as that, ways to process abandoned resins generated during the disposition have never been found out ( about 2011 ).
一
>>184
A method with RF-plasma at decompression ( 0.25 〜 0.9 torr ) also is one of the efficient ways to process abandoned ion-exchange resins.
This method can decrease secondary wastes such as tar and soot through complete oxidation by oxygen-atoms and radicals.
These active particles directly interact with ion-exchange resins and decomposed gases from those resins to pull hydrogens out of an alkyl group, and they oxidize hydro-carbons through cutting into c-c coupling.
So that, those resins are transformed into gases such as CO, CO2, H2O and the volume of them are reduced.
And, metallic ions such as CO sticking to exchange bases of resins are left as oxides in reduced remnants.
一
>>185
The method to process abandoned ion-exchange resins by this decompression way has following advantages because that is at low temperature compared with burning.
・ It's possible to decrease the shift of radioactive nuclides into gas-phase.
・ It's possible to reduce the quantity of issued gas because this method is a direct oxidative process by oxygen-plasma.
In a demonstrative test-device, processing ion-exchange resins of 4L for three hours,
the ratio of reducing volume was about 90 % .
Then, supplying oxygen into the system at 50 L/min , the RF-plasma was realized under the condition at 450 Hz , 10 kW .
一
>>186
And, a method to process abandoned ion-exchange resins by oxygen-thermal plasma under atomospheric pressure also is being considered to increase the speed of processing.
It has been reported that abandoned ion-exchange resins were processed at 4 kg/h through the oxygen-plasma generated by a transition arc-discharge ( 42 kW ).
In this case, the mixture ratio of positive ion-exchange resins and negative ion-exchange resins was 50 : 50 .
This processing by plasma was carried out together with glasses of 25 kg ( Na2O - Al2O3 - 2SiO2 ) to trap radioactive nuclides sticking to ion-exchange resins.
In this method to process, ion-exchange resins are supplied from the upper part of the system and they are dropped into the glass molten through arc-discharge.
一
>>188
And, a comparison of batch-processing with continuous processing has been carried out.
Batch-processing is a method to process ion-exchange resins put in a melting pot by an arc-discharge of 24 kW.
In this case, ion-exchange resins of 100 cm＾3 were processed, the ratio of reduced volume of 65 % on positive ion-exchange resins ( IRN 77 ) and the ratio of reduced volume of 90 % on negative ion-exchange resins ( IRN 78 ) were obtained respectively.
The condition of continuous processing was set up same as that of batch processing, IRN 77 was processed at 200 g/min , IRN 78 was processed at 63 g/min respectively.
一
>>189
The ratio of reduced volume in this case didn't depend on the speed to supply ion-exchange resins so much.
That ( the ratio of reduced volume ) of IRN 77 was equal to about 60 % , and that of IRN 78 was equal to about 90 % .
This result was approximately equal to that of batch processing.
But, as the heating of batch processing can't be uniform, it's hard to control issued gases in this case.
Meanwhile, in the case of continuous processing, it's comparatively easy to control the composition of issued gas.
一
>>190
As the method to process abandoned ion-exchange resins by thermal plasma is basically a kind of burning process by oxygen in plasma, oxygen or air is used as a plasma-gas for processing.
※ When using air, we should pay attention to the generation of NOx .
And, as COs sticking to ion-exchange resins are roughly gathered up to resins after processing, they are not shifted into gas-phase almostly.
一
>>191
The method to process ion-exchange resins under atmospheric pressure with blowing oxygen into plasma-jet also is being considered ( about 2011 ).
As time for processing goes, the weight of resins substantially decreases.
So, the ratio of reduced mass of 90 〜 95 % can be obtained for about 20 〜 40 minutes on the process.
And, from the result of infrared absorption spectrum, it has been confirmed that strong acid ion-exchange resin has a character that as time goes, the peak on sulfonic acid group decreases and that peak completely vanishes by the processing of 20 minutes.
Furthermore, it also has been confirmed that CO sticking to ion-exchange resin is divided into CO 0 and CO3O4 , Cs turns to be Cs2SO4 .

4.3 The Decomposition of PCB
The process to decompose PCB in oxidative mode with oxygen plasma or air plasma is being considered ( about 2011 ).
For example, a system to process liquid wastes by plasma-jet has been realized to load on a heavy-duty trailer.
※ PCB can be decomposed with supplying PCB into a plasma-jet of 327 kW at 0.4 kg/min through this method.
And, in the PLASCON-system stated previously, a plant to process PCB by blowing PCB itself together with oxygen into the system has been completed.
This PLASCON-system can process PCB at 40 〜 50 kg/h by reacting oil including PCB with oxygen through the DC-plasma jet of 150 kW .

And, a neutrino-detector called SK is put under the area neighboring to Hida.

5. The separation of matters by reactive thermal plasma
5.1 The separation of matters by hydric plasma
The 'high chemical activation' possessed by thermal plasma is suitable for the separation of components from mixture.
Generally, hydrogen is used for the reaction of high chemical active plasma.
And, hydrogen is used as a plasma-gas for arc-melting too.
Then, hydrogen is effective for refinements such as the devaporization from molten metals, the separation-removal of impurities.
Deacidifying, decarbonization and denitrogenization from molten steels, deacidifying, decarbonization from Ta and the refinement of Mo from molybdenum mineral deposites are being studied as processes to refine metals with the high chemical activation of hydrogen in thermo-plasma ( about 2011 ).
一
>>195
The withdrawing of Ta from a scrap of abandoned Ta-condensers is known as an application of hydric plasma to waste-disposal.
As Ta-condensers inserted into computers contain manganese and oxygen, efficient processes to deoxidize, de-manganize are needed to reuse them.
In particular, as Ta is one of the uneven distributed resources, an used Ta-condenser can be a precious secondary resource of Ta .
It has been realized to reduce concentrations of nitrogen, Fe, Ni as well as oxygen, Mn as impurities into about 100 mass ppm with only single manufacturing process through arc-melting process by hydric plasma.
一
>>196
The withdrawing of Zr from Zircoloy-scrap also has been carried out by hydric plasma.
Zr is utilized as Zircoloy to compose fuel-covering pipes of a nuclear reactor.
The scrap of large quantities of cutoffs and defective products which are generated in manufacturing of covering pipes also can be regarded as a secondary resource of Zr .
Zircoloy contains Fe, Sn, Ni, Cr, it has been attained to reduce Fe, Ni, Cr into 10 mass ppm and Sn into 100 mass ppm through arc-melting by hydric plasma ( about 2010 〜 2011 ).
一
>>197
In these processes, hydrogens dissociated in a plasma play important roles to remove impurities from metals.
But, its concrete mechanisms have never been made clear ( at 2011 ) .
For example, Mimura and others explained that temporal loose couplings of Fe and H like clusters are formed, so that the separation of Fe from molybdenum mineral deposite can be effectively carried out through hydrogen.
And, as suggested in a process to manufacture superfine particles with hydric arc, the compulsory vaporization-model of dissociated hydrogens also is considered as one of the factors.
一
>>198
This compulsory vaporizing action is a model that the generation of superfine particles is originated in reaction heat which is caused through recoupling-releasing processes of supersaturatively molten hydrogens in a liquid metal ( such as magma ).
Ohno and Uda asserted that speeds of vaporization for respective metals originated in this compulsory vaporizing action can be calculated out of a parameter Rp expressed with the following formula.
Rp ＝ ( − Δ H/L )・( nH2〈T〉／ nH2〈273K〉)
( 4 )
Then,
Δ H ; reactive heat to re-combine hydric atoms at temperature T
L ; latent heat to vaporize metals at T
nH2〈T〉; numerical density of hydric molecules at T
nH2〈273K〉; numerical density of hydric molecules at 273K
一
>>199
In the process to manufacture superfine particles of inter-metallic compounds with hydric arc, it's possible to control the composition of generated superfine particles through hydrogens in the plasma.
The higher the concentration of hydrogens in the plasma becomes, the more the composition of Ti in superfine particles of intermetallic compounds which are generated from the mixture of raw materials ( such as Ti , Si ) put on the positive pole ( anode ) gets.
As the pressure of steam of Ti is equal to about 1/10 of that of Si , the quantity of evaporation of Ti must be promoted to synthesize superfine particles of intermetallic compounds of TiSi2 .
Namely, we can control the composition of generated superfine particles by the concentration of hydrogen in an arc.
In this case, same results can be derived from the combination of Mo & Si or V & Si .
一
>>200
Accordingly, we have known that hydrogens contained in plasma play same role as a kind of catalyst to promote the evaporation of specific metals.
Considered causes are shown as follows.
( 1 ) Compulsory vaporizing actions by hydrogens dissociated in plasma
( 2 ) The increase of vaporized quantity because of thermal conductive ratio raised by hydrogens
( 3 ) The generation of intermediate products such as hydric-products
( 4 ) The change of activated quantity by hydrogens fusing into molten metal
The relation of the reactive parameter shown in formula ( 4 ) with the coefficient of separation derived from the composition of superfine particles has been made clear.
一
>>201
The coefficient of separation of the arc with hydrogen of 20 % is far different from that with hydrogen of 50 % .
This implies that the mechanism to promote the vaporization through hydric-arc is not originated in ( 1 ) and ( 2 ) .
So, it can be supposed that the promotion of vaporizing specific metals through hydrogens in a plasma is originated in ( 3 ) or ( 4 ) .
However, because intermediate products such as hydrite-products composed of molten metals ( including magma ) and hydrogens in plasma are unstable, it's difficult to experimentally examine them.
And, it also is hard to calculate out the change on activated quantities of a molten metal by hydrogens.
※ Magma also can be often regarded as a kind of molten metal.
By the way, technologies to make underground-tunnels and to deeply dig strata to the mantle by melting rocks through direct-current plasma have been developed.
>>202
5. The separation of matters by reactive thermal plasma
5.2 The separation of matters by chloric plasma
Hydrogens have mainly been used to cause plasma-reactions with applying 'high chemical activation' of thermal plasma until now ( about 2010 〜 2011 ) .
But, we have very few informations about plasma-reactions related to hydrogens such as thermo-dynamical data to realize such reactions ( for example, melting points, boiling points and steam-pressures of hydrogenated matters, etc ).
Therefore, it's difficult to theoretically study such processes.
一
>>204
In the case of chlorines in thermal plasma, the same as that of hydrogens, peculiar reactions happen.
Following merits are contained in chemical reactions of plasma with chlorines.
( 1 ) It's easy to generate chlorides with high pressured steam. And, it's possible to carry out special separations.
一
>>205
( 2 ) Values to describe material states of chlorides are very more than those of hydrogenated matters.
( 3 ) Chlorides are easier to analyze than hydrogenated matters because of its stability.
According to above merits, ways to separate matters from wastes with chloric plasma are useful to make clear mechanisms of the separation of matters.
Examples of separation of matters from metallic mixtures through chloric plasma are as follows.
一
>>206
We carried out separations of KOVAR-alloys ( Fe ＝ 53, Co ＝ 17, Ni ＝ 29 mass % ) through argon-plasma, argon-chloric plasma, argon-chlorine-oxygen plasma.
Those results are shown here. In the case of argon-plasma ( 10 L/min ), evaporated components were about same as those of KOVAR-alloy.
Accordingly, this means that three kinds of metals were mutually very similar in character and its speeds of evaporation also were about equal mutually.
一
>>207
In the case of argon-chloric plasma ( Ar ; 10 L/min , Cl 2 ; 0.25 L/min ), Fe selectively evaporates.
And, in the case of argon-chlorine-oxygen plasma, if the flux of oxygen is small, Fe selectively evaporates.
Meanwhile, if the flux of oxygen increases into 1.0 or 2.5 L/min , the evaporation of Fe is suppressed to generate oxides with low steam-pressure.
Furthermore, the concentration of Co in hume becomes higher to generate chlorides with high-pressured steam.
So, we can separate components of Fe or Co from Fe-Co-Ni alloys by chloric plasma.
一
>>208
Changes on free-energy ( Gibbs ) were taken into account to study such selective mechanisms to separate.
The concept of change on free-energy by Gibbs can be applied to the selective evaporations of Fe in cases of argon-chloric plasma or argon-chlorine-oxygen plasma.
※ Especially, the latter case had a small-sized flux of oxygen.
一
>>209
It's known that there are correlations between concentrations of elements in hume and changes on free-energy in chloric reactions of respective elements with chloric atoms, the bigger the changes on free-energy of chloric reactions get, the higher the concentrations of elements in hume become.
一
>>210
Namely, the efficiency for separating components with chloric plasma depends on progressive situations on chloride reactions of respective components.
Material states of Fe, Co, Ni are very similar mutually. However, those changes on free-energy related to chloride reactions are different reciprocally.
So that, it's possible to separate those components from alloys.
一
>>211
Accordingly, it's likely that a mechanism to selectively separate specific materials from other matters through chloric plasma is originated in the generation of chlorides from molten metals and chloric plasma.
So, it's probable that some mechanisms to separate specific materials from other matters and a special evaporating-mechanism by hydric plasma are 'not' originated in compulsory evaporating actions by hydrogens dissociated in plasma, the formation of temporal products such as hydrogenated matters is one of the main factors to cause such special mechanisms.
Tentatively, it's possible to reduce waste disposal-cost by properly using high chemical activations of thermal plasma and characters at high temperature.
※ An example ;

Furthermore, there are realizable processes with only thermo-plasma.

・ Thermal plasma is being used to melt flying dusts generated from burnt urban garbages.
・ A method to process urban garbages containing a set of burnt／melted dusts.
・ The decomposition of respective gases used in processes to manufacture semiconductors. The process for removing gases with reactive thermal plasma is effective in decomposition.
・ Reactive thermal plasma is effective to completely decompose SF6 used in large quantities for circuit breaker.

It's reported that 'magnetic monopole beams' generated from the following topo-logical circuit can control decays of radioactive nuclides.
>>180-192
Ways to dispose of abandoned ion-exchange resins with thermal plasma are shown here.
In fact, it's possible to experimentally demonstrate an interesting phenomenon with superpositions of wet negative ion-exchange films and wet positive ion-exchange films.
The demonstration is as follows.
>>216
Some magazine carried an article about the so-called 'perpetual pump' invented by Tsuyoshi.Iai ( 1990 ).
The summary of the article is as follows.
「・・・ Superposing a wet positive ionic exchange film on a wet negative ionic exchange film, irregular Brownian motions of water molecules are spontaneously arranged around the junction part.
And, water moves from the side of positive ionic exchange film ( 〈+〉) to the negative ionic exchange film ( 〈−〉) .
>>217
In this case, we used a film with smoothed surface as an exchange film, put in order to be 〈filter paper〉ー 〈 ＋ 〉ー 〈 − 〉ー 〈filter paper〉, this order is 'sandwiched' with two smoothed sheets and the 'sandwich' is pressed down.
Under such a simple structure, water oozed out of around the latter filter paper.
We could obtain a 'perpetual pump' by gathering oozed waters and leading them into a glass tube.
一
>>218
The same thickness as a hair is enough to make a passage from a filter paper to a glass tube, meanwhile we have to prepare the mechanism so as not to leak water on the way of passage.
Then, in the picture of the magazine, the passage of the pump is composed in order to be 〈filter paper〉ー〈+〉ー〈−〉ー〈filter paper〉ー〈+〉ー〈−〉ー〈filter paper〉・・・, its surround is congealed with epoxy resins.
More than 10 years have passed since manufacturing the pump, but the pump is drawing water still more ( in the beginning of the 1990's ).
Accordingly, it has been confirmed that the second law of thermodynamics is wrong. ・・・」
(→ 〝Maxwell's demon″ )
一
>>219
A chief of some section of the National Science Museum ( K.Aoki ) also received the pump and told as follows.
「This device is so simple, ion-exchange films are only stuck on the way of the lower part of C-type glass tube, the device doesn't have other mechanisms.
But, surely, waterdrops are coming through the sheet every ten and several minutes, although more than one month have passed after receiving the device, such a situation is constantly continuing.
The inventor explained 'random motions of water-molecules are arranged in specific directions by ion-exchange films stuck on the lower part of C-type glass tube forming a circuit of water' .
But, I can't sufficiently understand of that.
I don't believe in perpetual motion and don't think that this device is a perpetual motion.
However, at present, I have never been able to rationally explain of this phenomenon.」
一
>>220
We have heard that the principle same as this case can be applied to an electric current according to Iai's private messages.
「・・・ Even if a circuit is made of a circular wire, an electric current doesn't run through the circuit.
But, even in this situation, electrons are not stationary, some electrons move to the right and other electrons move to the left due to diffusion.
Merely, it seems that electric currents don't run through the circuit because of the balance of both electrons.
Then, inserting an asymmetric component ( for example, thermo-coupling. However, as a heating process is added to this component, this can't be a perpetual cell ) into this circuit to break down the balance, an electric current is spontaneously generated. ・・・」
※ It's significant to insert (≒ immerse) an asymmetric element into the circuit for breaking down balance or symmetry (→ structures far from equilibrium, symmetry-breaking including ground-figure switch).
一
>>221
Furthermore,
「・・・ We have been able to find out a proper component for the circuit.
The 'perpetual pump' is a mere demonstrative model, meanwhile various practical ways applying its principle to electronics can be presented.
So, actually, it's being continued to improve the mechanism so as to semi-permanently extend its lifespan in comparison with batteries on the market. ・・・」

There is a mentioning 'oni-no-kubi wo totta yo-ni (鬼の首を取ったように)' in Japanese.
