Escopo e aplicabilidade

This standard applies to the monitoring of effluents at all nuclear facilities involved in the processing and handling of radioactive materials. It covers the monitoring objectives, planning principles, and technical requirements for both airborne and liquid effluents. It is mandatory for operators of nuclear reactors, fuel processing plants, and radiochemical laboratories to comply with these monitoring regulations. The standard references GB 11216 for quality assurance requirements.

Requisitos técnicos

GB 11217-1989 establishes the fundamental principles for developing an effluent monitoring plan at nuclear facilities. It requires facilities to define monitoring objectives, select appropriate monitoring points downstream of waste treatment systems, and determine the necessary sampling frequency and radionuclide types. Facilities must ensure that all potential radioactive discharges are subject to routine monitoring. The standard outlines specific monitoring strategies for different types of facilities, including nuclear power plants, fuel reprocessing plants, and uranium/plutonium processing facilities. It specifies requirements for monitoring airborne effluents (such as noble gases, iodine, and aerosols) and liquid effluents (including tritium and various fission products). Continuous monitoring is required at critical release points with high potential for unplanned releases. Regarding instrumentation, the standard mandates that monitoring equipment must have a sufficiently wide measurement range to accommodate both routine and unplanned releases. Redundant monitoring systems must be installed at key discharge points to ensure reliable data during accidents. The standard also details the requirements for data recording, reporting formats, and archiving, specifying that records must be retained for at least ten years post-decommissioning.

Métodos de ensaio

The standard specifies several sampling and measurement techniques to characterize radioactive effluents. Sampling methods include continuous proportional sampling for variable discharge rates and periodic sampling for stable concentrations. Measurement approaches encompass direct measurement, on-site measurement, and laboratory analysis for comprehensive radionuclide identification. Facilities must utilize standard testing techniques or obtain approval for any non-standard methods. Quality assurance procedures must align with GB 11216.

Perguntas frequentes

What types of facilities are regulated under GB 11217-1989?

GB 11217-1989 applies to all nuclear facilities that handle, process, or store radioactive materials. This includes nuclear power plants, research reactors, nuclear fuel reprocessing plants, uranium and thorium processing facilities, and radiochemical laboratories.

What are the reporting requirements for effluent monitoring under this standard?

Facilities must submit routine monitoring reports to the competent authorities on a quarterly or semi-annual basis, depending on the scale of radioactive discharge. In the event of a severe unplanned release, an initial report must be submitted within 48 hours of detection.

Does GB 11217-1989 specify limits for radioactive discharges?

The standard defines the concepts of management limits and operational limits but does not specify the exact numerical values for radioactive discharge limits. Instead, it requires facilities to monitor effluents against the limits established by regulatory authorities and internal operational guidelines.
