Expected Results

Impulse systems using an energy of explosive substances for dividing radioactively polluted structures, pipelines of NPP circulating contours being deduced from exploitation, as well as multi-layer pile footings of stationary off-shore platforms, used for extraction of petroleum and gas on a continental shelf will be created. These impulse systems of division will be supplied by protection facilities, locating action of impulse impact and lowering influence of its collateral factors on people, environment and structures up to allowable level. System of local monitoring and package of applied computer-aided programs for controlling and prognosticating levels of explosion side effect will be created.

Planned development will find application at liquidation failure after-effects and under extreme situation, at dismantling radioactively polluted equipment of NPPs, deduced from exploitation and, probably, at carrying out of repair jobs in a zone of radioactive radiation on acting NPPs; at dismembering radioactive waste and radioactively polluted structures and so on in ChNPP 30-km zone on purpose to utilize them; at dismantling stationary off-shore platforms for oil-gas-production, which remove out of operation, underwater and ground pipelines, in a fuel and energy complex, and also on large-sized structures. Moreover the impulse systems of division can be used to prevent emergency and extreme situation or to eliminate their after-effects, when mobility, autonomy, speed of action and remote control of elaborated systems are important.

In a number of cases the impulse systems due to their unique characteristics have not alternatives in application. Cutting pipelines by impulse pipe-cutters is carried out 3...10 times faster as compared with a mechanical one. Devices for underwater explosion cutting will allow to reduce time of execution of underwater work by a factor of 2...5, and consequently, time of using subsidiary ships, as compared with conventional plasma and/or electropowder methods of cutting metal structures. Dozes of irradiation of the personnel are respectively reduced at realization of work on NPPs or under condition of radioactive pollution and expenses on dismantling large-sized structures.

The structure of the project as to expected milestones can be conditionally divided into two interconnected parts.

The part of the project, executed in first two years, provides theoretical, methodical and experimental investigations as regards development of impulse systems of division and system of local monitoring, manufacturing and testing their pre-production models

The second part of the project, executed a third year, assumes development of impulse technologies of dismantling elements of structures of fuel and energy complex and their approbation in ChNPP 30-km zone and on off-shore aquatory.
