適用範囲
This standard applies to the interim storage of low- and intermediate-level radioactive solid wastes generated from any practice. It specifically covers the management, operational, and safety requirements for waste interim storage facilities prior to final disposal. Please note that this standard is not applicable to the storage management of tailings and slag-type radioactive solid wastes. It references the classification system defined in GB 9133 for determining waste levels.
技術要求
The standard outlines the fundamental principles for waste interim storage, emphasizing classified collection, standardized packaging, safe transport, and retrievable storage. A critical requirement is that the interim storage period for wastes shall not exceed five years. The management objective is to prevent the unacceptable release of radioactive materials into the environment and ensure public and occupational exposures remain below corresponding dose equivalent limits. For the storage facilities, the standard mandates that site selection, evaluation, design, and construction must be undertaken by state-approved entities. Facilities must possess high space utilization, ensure waste retrievability, and demonstrate resistance to natural disasters (e.g., fire, water, earthquakes). Facilities are required to install necessary ventilation and filtration systems, dosimetry monitoring instruments, and decontamination equipment to prevent any leakage of radioactive substances beyond established limits. Regarding operational limits, the standard strictly controls the received waste's specific activity, weight, and dimensions to not exceed the facility's protective and handling capacities. Wastes must be properly classified and packaged. Containers must not contain free liquids (less than 1% by weight), flammable materials, pathogens, or non-radioactive highly toxic substances. The surface dose rate and loose radioactive contamination levels on the exterior of the packaging must strictly adhere to the specified safety thresholds. The standard also details the administrative responsibilities of the operating organizations, competent authorities, and safety supervision departments. Operating units must obtain operational licenses, establish emergency plans for potential radiological and non-nuclear accidents, and submit annual reports detailing waste inventory, personnel exposure, and operational summaries.
試験方法
The standard requires rigorous verification and monitoring procedures rather than specific laboratory testing methods. Key evaluation procedures include surface contamination monitoring (measuring alpha and beta activity) and dose rate assessments (surface and at 1-meter distance) for incoming waste packages. Facilities must also conduct routine environmental dosimetry monitoring and aerosol concentration checks within the storage area to ensure compliance with radiological protection limits.
よくある質問
What products and facilities are regulated under GB 11928-89?
The standard applies to the interim storage of low- and intermediate-level radioactive solid wastes generated from any practice. It explicitly excludes the storage management of tailings and slag-type radioactive solid wastes.
What is the maximum allowable interim storage period for radioactive solid waste under GB 11928-89?
The standard mandates a maximum interim storage period of five years. After this period, or if the waste's specific activity remains above the exemption value, it must be transferred for final disposal within the timeframes stipulated by national regulations.
How does GB 11928-89 relate to other Chinese radiation protection standards?
It works in conjunction with GB 4792 (Basic Standards for Radiological Health Protection), GB 8703 (Regulations for Radiation Protection), and GB 9133 (Standards for Classification of Radioactive Waste) to ensure comprehensive radiological safety and proper waste categorization.
