For radioactive waste generated at nuclear facilities, the identification of its radiation characteristics during its conditioning in accordance with waste acceptance criteria is considered as a relevant task to accomplish. JSC VNIINM has developed Unified Guidance for Measuring the Radiation Characteristics of Waste. The Guidance specifies the premeasurement and measurement procedures, including the waste generated during decommissioning, and standard procedures for measuring the specific activity of radionuclides in packages and in samples considering sampling flowchart for solid RW in the form of construction waste, plastic compound, fragments of equipment, PPE, soils. Algorithms allowing to check the measurement accuracy using certified items were developed.

The paper discusses the comprehensive measures implemented to ensure the uniformity of measurements as regards the RW characteristics demonstrating their compliance with waste acceptance criteria for disposal. Under this framework, the following regulations have been developed by JSC VNIINM: the Unified Industry Guidelines for the Measurements of Radiation Waste Characteristics, standard measurement and test procedures, as well as the standard of the State Corporation Rosatom for monitoring physical and chemical property indicators and characteristics of the RW form.
