Preparation for Decommissioning the U-5 Facility Building Complex at VNIINM

Abstract

A range of preparatory tasks for decommissioning the U-5 facility at VNIINM was performed in 2010–2016. Comprehensive engineering and radiation inspections were conducted, and cartograms of contamination were constructed. Deposits in the special utility systems were investigated. A detailed investigation of the contamination of the building structures was performed. Radioactively contaminated process media, sources of ionizing radiation, and radioactive wastes from technological equipment and rooms were removed. Design documentation for decommissioning the U-5 facility was developed and a positive final report by a government environmental commission of experts, final sanitary-epidemiological reports, and licensing for decommissioning were obtained. The measures made it possible to increase the radiation safety of the facility and prepare it for decommissioning.
