Safe storage of RW

FSUE RADON performs processing and conditioning of RW for long-term safe storage. Services rendered include as follows:

• development of a method ensuring preservation of "historic" storage facilities;
• development of a method ensuring final isolation of RW;
• creation of storage facilities of a new type;

Besides, RADON performs complex monitoring of storage facilities for RW, and makes an assessment of radiation safety at nuclear-hazardous facilities.
Development of a method ensuring preservation of "historic" storage facilities

• Elimination of faults with engineered barriers accumulated during long-term localization of RW at storage facilities.
• Development and optimization of design for the upper multi-functional coating of storage facilities.
• Creation of a monitoring system for RW body and for the multi-functional coating.

Creation of storage facilities of a new type
Preparation of technical proposals on construction and operation of storage facilities as large diameter wells

• Determination of parameters for basic structural elements of storage facility depending on mine engineering conditions;
• Organization of work on construction site (including work in tense conditions such as operating surface storage facilities);
• Choice of load-lifting facilities and of non-standard equipment for RW loading into and unloading from storage facility;
• Installation and adjustment of automated system to monitor air-tightness at storage facility and pump out water (if required).

Complex monitoring of RW storages and assessment of radiation safety at nuclear-hazardous facilities

• Collection and analysis of input data for safety assessment including filtration and sorption experiments in laboratory conditions and in situ;
• Forecasts of radionuclides migration, and assessment of radiation environment for normal operating conditions and for evolution of engineered barriers;
• Safety assessment including elaboration of assessment context, scenarios, models, and also estimated calculations and analysis of results obtained;
• Determination of maximal RW activity for RW mortuaries/sites for long-term storage of RW based on safety assessment;
• Grounds for possible extension of service lives for operating RW storage facilities;
• Investigation of physical degradation of matrix material and of storage facilities structures;
• Assessment concerning distribution of radionuclides and total residual activity within storage facility;
• Investigation of geochemical conditions within storage facility and in soils of the border zone;
• Assessment of migration processes and of radiological hazard at storage facility;
• Creation of geomonitoring system.
