Shelter Object peculiarity is determined by its potential hazard, significantly higher, than permitted by existing norms and the rules for facilities, containing nuclear and radioactive materials. Safety assessment of any nuclear engineering or industry facility, as a rule, is based on practical operating experience of this and similar facilities. The Shelter has no even close analogues.
Starting from 1986 to date, not more than 60% of the Shelter (Unit “Á”) premises have been surveyed. The remaining premises are inaccessible due to high-level radiation fields, or due to permeability barriers occurred during explosion, which led to structure destruction and initiation of lava-like fuel containing materials, and during concrete pumping-in when erecting the Shelter. Thus, significant part of the facility remains unexplored area, being one of the most serious present-day risks.
