THE SYSTEM LOCALIZE OF RADIOACTIVE DUST UNDER INTO THE ROOF SPACE OF OBJECT
Cover not present THE SYSTEM LOCALIZE OF RADIOACTIVE DUST UNDER INTO THE ROOF SPACE OF OBJECT
Category: Number 28
Publication: 28
Summary

The system localize of radioactive dust in an object "Ukryttya" performs the duty of withholding of radionuclidess in the set limits. A function includes localization of radio-active dust, by causing of the polymeric sheeting on muddy surfaces, settling dust from air of subroofing space by means of irrigation of space solution which settles dust. Systems and methods for controlling the protective properties of the polymer coating in the object "Ukryttya". After the relevant reconstruction the updated dust-suppressing installation (UDSI) could be used at the phase of new safe confinement putting into operation. During full/partial dismantlement of unstable constructions the UDSI would be also dismantled, its functions being transferred to the mobile dust-suppressing installation.

Keywords: function of safety, dust-suppressing installation, localize polymeric film, standard company, evaluation of the state of film.
