Investigation of water flows inside of Ukrytie object

Superior limits of moisture admission in the most danger places of the B block and accessory systems of reactor part (RPAS) of the Ukrytie object by means of atmospheric precipitation (1950 m3/year), condensation processes in spring-summer period (1650 m3/year) and from technogenic sources (180 m3/year) are estimated. It is shown that moisture is removed from the Ukrytie object due to evaporation in autumn-winter (september-april) period (2100 m3/year) and as a result of not organized leaks. Using tracer method basic water flows inside the Ukrytie object and dynamic of leaking of block water from northern part of the 4-th block are determined. Experimental investigations show that as a result of not organized leaks from 001/3 room of RPAS of the 4-th block not less than 1000 m3/year of highly radioactive waters leak into drainage system of the 3-d block
