Introduction
So far, the common practice of radioactive waste treatment in Russia was controlled temporary storage – the so-called “procrastinated decision”. In Russia, the total amount of accumulated liquid radioactive waste (hereinafter LRW) is 477 million, and 77 millions of solid radioactive waste. However, as the world and Russian practice shows, that the controlled storage of radioactive waste in the long term results their accumulation and is not acceptable as a strategy of RAW treatment. Such strategy does not lead to the final safe solution of the problem, but requires the permanent overhead costs without clear prospect [1].

Thus, high production complexes for LRW treatment are needed. Key consumers interested in of liquid radioactive waste treatment plants are:

• enterprises of spent fuel treatment;
• existing nuclear power plants with power and research reactors;
• enterprises involved to decommissioning of boats and ships with nuclear power plants;
• enterprises involved to decommissioning of nuclear power plants and research reactor
installations;
• enterprises involved in the liquidation of the consequences of nuclear accidents
(Chernobyl, Fukushima , etc.).

Nowadays, mainly thermal and sorption methods are used for treatment of liquid radioactive waste. Using these methods, the main part of liquid radioactive waste, produced during the operation of nuclear installations of various purposes and other facilities using radioactive substances, is treated. These methods cannot be called original or specific for the treatment of radioactive waste (hereinafter RAW), because they were taken from various conventional industries and modified. Mainly these are methods, usually used in purification, treatment and desalination of water.
For implementing of treatment methods of non-nuclear industry and their modification, the specific requirements of industries related to radiation must be taken into account [2]:

• leak tightness of the equipment, excluding the possibility of radioactive contamination of buildings, staff and the environment;
• feasibility of the equipment operation to minimize the need for maintenance services in the radiation conditions, which require complicated and expensive works of equipment decontamination.

The most universal method for treatment of almost all types of LRW is a thermal method, in which LRW solution is evaporated to concentrate radioactive products in a small volume.
Practice of LRW treatment shows that the main source of problems in evaporation equipment are the heat exchange pipes. During the operation, their surface is covering inevitably by sediments, which have to be removed periodically by chemical washing, with interruption of the treatment process and at the same time with producing a large amount of secondary LRW. This inevitability is caused by evaporator’s design including heat exchange tubes – the process of sedimentation of the tubes cannot be prevented, it can only be decreased by using different methods: increasing the circulation velocity in heat exchange tubes or addition of special chemicals additives. The inevitability of foam-and-droplets entrainment from the evaporator is also caused by its design, so the additional special equipment have to be used for steam and condensate purification from radionuclides. Moreover, it is necessary to perform periodically the mechanical cleaning of heat exchange tubes which leads to important radiation doses to personnel.
All these problems existing in LRW evaporation technology are well known and studied, and some alternative methods are considered in [2], but it is concluded that these methods have a low productivity and heat transfer because of the lack of an organized circulation of evaporated solution [2].
The ideal comprehensive solution of the problem of LRW treatment is to create a continuous LRW evaporation technology with cementation of the concentrate at the same time, and the possible addition of used sorbents and sludge to the resulting cement compound. The main factor limiting the use of evaporation technology is a high energy costs, but with the appearance at energy market such installations as E-Cat, this problem disappears.
For comprehensive solution of the problems of LRW concentration and its subsequent cementation it is proposed to establish a technological process based on the two following principles:

1. To perform the process of LRW concentration in the evaporator equipment, that helps to prevent droplet entrainment and excludes degradation of technological parameters in time (to exclude interruptions in work of evaporation equipment due to fouling of the heating surface).
2. To make the processes of evaporation (secondary evaporation) and conditioning of LRW (inclusion in cement matrix) sequental and continuous, thereby eliminating the need for a large number of intermediate containers and dosing of separate portions.

    The technology of the Uzikovs is surely intelligent, but after this publication I did not see a substantial follow up of it. I think that the colossal business of the reposition of the radioactive wastes bars the development of such genial solutions.

    I have read this important paper of Dr Irina and Vitaly Uzikov, published months ago; In a simple and economical way this technology can resolve part of this enotmous problem of the radioactive wastes treatment, but it seems nobody reacted to this important publication. Perhaps the business of the accumulation and storage of this material prevails on the necessity to reduce these wastes to protect the health of the people.

    You’ve mentioned that the quarkX has material problems and operates at 1400 degrees C. Single crystal sapphire has a maximum useful operating temperature of 2000 degrees C. See: http://www.crystals.saint-gobain.com/uploadedFiles/SG-Crystals/Documents/sapphire-material-products-properties.pdf It can also be obtained in various shapes. Are you currently using this material?

    Dear James,
    If we are speaking about, for example, PUREX process (Plutonium-Uranium Recovery by EXtraction), the proposed system can be used for treatment of low-level and medium level radioactive solutions, which were formed while this process. However, for the treatment of the high-level radioactive waste containing fissile elements, actinides and transuranium elements, it is not appropriate due to the specific requirements for the treatment of such waste.
    Best regards,
    Irina and Vitaly Uzikov

  • James Santigo

    Dr Irina Uzikova & Dr Uzikov:
    Could be your system useful also for high level radioactive wastes, e.g. spent nuclear fuel ?
    Thanks,

    Drew G.:
    Finmeccanica has the right to use the name “Leonardo”, as well as we have. It is inspired from Leonardo Da Vinci, whose name in itself can’t be object of intellectual property.
    It could be a case should Fimneccanica make anything in specific competition with us, but this is a colossal concern, with interests not including our field.
    Good luck to Finmeccanica, now Leonardo !
    Warm Regards,
    A.R.

  • Drew G.

    Finmeccanica has rebranded as Leonardo. Looks like a name conflict with your enterprise.

    Dr Andrea Rossi
    A poll made yesterday confirms that people trust in you has increased after the complaint against IH, notwithstanding their massive attack against you made with powerful financial means.
    How do you explain ?
    Cheers,
    Dixy

  • Andrea Rossi

    Jona:
    I have written a paper with the mathematical models to explain this, and the essence is in the Reverse Mossbauer Effect.
    I am still afraid to publish it, more study has to be done and I want not to burn it prematurely in the battlefield, but the more I study, the more I am convinced of it.
    I gave the draft of my paper to several scientists to explain me where am I wrong. Should it be possible to publish it just as a draft, not as a publication, I would do it, to collect critics and understand better, but I am afraid to do this move, for obvious reasons.
    Warm Regards,

  • Steve Roberts

    Dr Rossi – The ERV will tell the story. According to Industrial Heat they seen no value in the results and THEY will continue to research LENR with their shell companies; its clear that Industrial Heat intentionally violated your non disclosure and IP.

    ** If I were a Woodford investor right now I would be Very concerned.

    Dear Mr Renoir,

    It is logical that for global transformations, especially in such important field as the energy field, all factors should be taken into account – environmental, economic, political and social. I agree with Andrea Rossi, who sees also problems in complete and immediate transition to new energy type, and not just advantages. For now, only Andrea Rossi has full information about the potential of the new energy source, and what consequences may have inconsiderate strategy of its implementation. As for nuclear energy and nuclear reactors, even taking into account it’s disadvantages (risks of radiation accidents, and radioactive waste), they will be able to continue to perform useful functions in future, such as, for example, non-destructive control, the production of isotopes for diagnostics or treatment of cancer. Of course, it can be quite other nuclear reactors to perform these tasks – so-called hybrids (working in conjunction with the accelerator) and subcritical reactors (reactors without risks of uncontrolled power acceleration).

    Best regards,

    Vitaly and Irina Uzikov

  • jcr

    Dear Dr Uzikov & Dr Uzikova:
    What do you think, as experts of the matter, of the fact that Andrea Rossi continues to say that all the energy sources, included the nuclear power plants, have to be saved and integrated, instead of substituted with alternative energy ?
    Thanks,
    JC Renoir

    Dear Marco,
    We were spoken about “classical” closed Thorium fuel cycle in conventional reactors (and not hybrid reactors as Rubbiatron). Thorium fuel is considered as a fuel for a lot of new conceptions of reactors (for example there is a conception of Molten Salt Fast Reactor, which uses molten salt as a fuel and a coolant in the same time). 100 years is taken from the fact that for now there are only conceptions of such reactors. Usually for nuclear reactors it takes a lot of time from conception to the real project and construction. Moreover, not only the reactor, but all the chain of the cycle (mining, isotopes separation, recycling of fuel) should be elaborated. So new installations for these processes should be constructed. That will require a lot of time, taking into account that for now a lot of military Plutonium should be “burnt” in nuclear reactors.
    As for hybrid reactors, indeed, for example Bogomolov proposed to use backward wave linear accelerators of protons (BWLAP), but the work hasn’t been completed, so for now it is too early to speak about specific dates of construction. In such reactors not only Th-232, but also spent nuclear fuel and U-238 can be used (nowadays a lot of U-238 is stocked at enrichment facilities) .But so far there is no experimental verification of this sector and identification of all its advantages and disadvantages; so it is difficult to speak about its development. Even if to take into account utilization of long-lived actinides in such reactors, the quantity of minor actinides (isotopes of Am, Km, Np) will be huge, and the problem of radioactive waste remains
    Best regards,
    Irina and Vitaly Uzikov
