Introduction and Overview

The purpose of the Project is to develop the new generation of technologies for impulse dividing metal structures, which will allow using them widely on objects of nuclear power engineering and under extreme situation. The technological, design and introduction store, accumulated by the collective-executors for about 25...30-years period of work in this direction is an initial position for the project accomplishment. Advantages of explosive technologies (such, as mobility, speed, reliability, cheapness and opportunity of remote control) frequently make their use non-alternative. At the same time, the factors of danger and ecological pollution, inherent to blasting as such, much limit an area of its application. Experience being available of the collective-executors allows to expect that, during the course of this Project fulfilment some important restrictions will be much eliminated.
As a result of the Project fulfilment there will be the new generation of impulse systems of division (device of division in a combination with protective means, systems of remote control and monitoring) and technologies based on their use adapted to decision problems, which will be especially topical in the long term of the nearest years and decades.
Problem of liquidation of ChNPP failure after-effects including a problem of extracting fuel-containing materials and radioactive waste from object "Sarcophagus" and also salvaging radioactively polluted metal structures and buildings in 30-km ChNPP alienation zone deserve especial attention. Traditional explosive technologies because of collateral factors such as shiver formation, shock waves, and dust transference are inapplicable, despite their speed, reliability and efficiency. The new generation of impulse technologies will save all advantages of an active constituent of explosive technologies, but thus full suppression of the indicated harmful collateral factors of explosion will be guaranteed.
Application of impulse technologies assumes control of radiological and physical parameters influencing environment and person. Necessity of such control is especially important at managing work on such objects as "Sarcophagus", at liquidation of after-effects of failures on objects of heavy-duty application and under conditions of radioactive pollution.
Thereby in the Project great attention is given to development of blocks of local monitoring system, including modules of operative processing and transferring information for tracking a situation and acceptation of adequate decisions by staff, carrying out work. Experience in execution of such work under conditions of radiation contamination is nowadays absent.
Consolidation of efforts of the professionals of various profile within the framework of given project will allow to reach qualitatively new level of decision of complex problems connected both with liquidation of after-effects of failures and their prevention. Remote controlling work in a combination with opportunity of robotized use of development will allow decreasing drastically rem-unit expense at all stages of accomplishment of work under condition of radioactive pollution. Impulse systems of division and the system of local monitoring will be tested in ChNPP 30-km zone and on off-shore aquatory. The technological schemes of their application in extremes and emergencies, technology of dismantling NPP circulating contours and multi-layer supports of off-shore stationary platforms will be elaborated.
Thus just these circumstances determine a place of the present Project in world practice and its relation to the world scientific level. As existing so projected elements of developed systems will correspond to a world technological level, and the organization-executors concern to a number of few organizations conducting work in the area and are well known to the specialists.
