Alcance y aplicabilidad

This standard specifies the basic requirements, acceptance criteria, and quality assurance for the near surface disposal of low and intermediate level radioactive solid waste. It applies to all waste sent to near surface disposal facilities, primarily originating from nuclear power plants, nuclear fuel cycles, and the decommissioning of nuclear facilities. Waste generated from the production and application of radioactive isotopes should also refer to this standard.

Requisitos técnicos

This standard comprehensively outlines the acceptance criteria for radioactive waste packages, focusing on physical, chemical, and radiological properties. It mandates that the radionuclide content and specific activity must not exceed administrative limits, and fissile material must be restricted to prevent nuclear criticality. Furthermore, it specifies limits for surface radiation levels and non-fixed surface contamination. The standard requires adequate mechanical stability and compressive capacity for waste packages, alongside strict controls on chemical composition. Waste forms must not contain pyrophoric, explosive, or low-flash-point flammable substances, and the content of chelating and complexing agents must be strictly limited. The waste body must exhibit sufficient thermal and radiation stability, as well as resistance to fire and microbial degradation. Additionally, it restricts free liquids, gas generation, and mandates specific requirements for packaging containers, including a minimum filling volume of 85% and proper labeling.

Métodos de ensayo

The standard outlines evaluation and inspection procedures primarily through referenced standards such as GB 12711 and the GB 14569 series. Testing encompasses verifying surface dose rates, surface contamination levels, and mechanical integrity. Authorized departments may conduct destructive or non-destructive sampling inspections to evaluate total beta-gamma and alpha radioactivity, leaching rates of major radionuclides, chemical composition, and thermal performance. Quality assurance protocols also mandate the verification of labeling, structural integrity, and tracking of waste package data.

Preguntas frecuentes

What products and facilities are regulated under GB 16933-1997?

The standard applies to low and intermediate level radioactive solid waste sent to near surface disposal facilities, primarily originating from nuclear power plants, the nuclear fuel cycle, and the decommissioning of nuclear facilities. Wastes from radioisotope production and application should also refer to this standard.

How does GB 16933-1997 relate to specific disposal site requirements?

The standard establishes baseline criteria. Specific disposal sites must develop their own operational acceptance documents based on site characteristics and safety evaluations, ensuring their requirements are not lower than the baseline provisions of this standard.

What international guidelines is GB 16933-1997 based on?

It was primarily referenced from the International Atomic Energy Agency's 1985 Safety Series No. 71 Report, Acceptance Criteria for Shallow Land and Cavern Disposal of Radioactive Waste, while being adapted to China's specific conditions.
