The issues of organization and safety during decommissioning of nuclear power facilities of the nuclear fuel cycle, including those located in dense residential development, in particular JSC “VNIINM” are discussed. On the example of the already completed decommissioning of the building “B” of JSC “VNIINM”, a description of the successful organization and implementation of radiation safety of decommissioning of a radioactively contaminated building in the dense urban development of the city of Moscow is given. Measures to ensure radiation monitoring during the decommissioning of the building “B” are analyzed. It is shown that the radiation control carried out in accordance with the project documentation for decommissioning of the building “B” included the measurement of radiation characteristics of the dismantled equipment and communications, building structures, and disposed waste. 339 039 measurements were carried out, which is 1.9 times higher than the number planned in the project documentation. The article describes the use of personal protective equipment, which allowed, along with compliance with the sanitary and access control regime, to completely exclude the ingress of radioactive substances on the mucous membranes and skin of personnel, and to ensure the standard dose load of personnel. The comparison of design and actual indicators for decommissioning of the “B” building, design indicators for decommissioning of the U-5 installation, and the building “Zh” of the JSC “VNIINM” was made.
Keywords: decommissioning, radiation safety, radiation control, personal protective equipment, waste.
