Foreword

This standard was drafted in accordance with GB/T 1.1-2009 given rules. The standard proposed by China National Nuclear Corporation. This standard by the National Standardization Technical Committee on Nuclear Energy (SAC/TC58) centralized. This standard was drafted. Institute of Nuclear Industry Standardization. The main drafters of this standard. LUO Geng, Xia Yihua, Sun Donghui, Zhang Xin. Landfill disposal of low level radioactive waste

1 Scope

This standard specifies a very low level radioactive waste (hereinafter referred to as low-level radioactive waste) basic requirements for landfill disposal, including the disposal of principle, filled Underground disposal activity concentration guidance values, as well as dedicated siting, design, construction and operation requirements landfill landfill closure requirements. This standard applies to low nuclear power plants, operation and decommissioning of nuclear technology and nuclear fuel cycle facilities use activities arising from radioactive waste Landfill disposal. This standard does not apply to the disposal of tailings uranium (thorium) generated by mining and metallurgy, waste rock.

3 Terms and Definitions

The following terms and definitions apply to this document. 3.1 VLLW verylowlevelradioactivewaste; VLLW Very low levels of radioactivity, can landfill disposal of solid waste in shallow waste, which contains short-lived artificial radionuclides activity Concentrations higher than the exempt level, but not higher than the value of the activity concentration of the standard recommended activity concentration guidance values \u200b\u200bor approved by the regulatory authorities. 3.2 (Low release) waste landfill VLLWlandfilsite Landfill disposal of low - level radioactive waste landfill. Including the disposal of a large number of low-level radioactive waste approved by the regulatory authorities (or approval) of engineered landfill Farm or other regulatory authorities approved landfill (such as the use of mine waste). 3.3 Activity concentration guidance values \u200b\u200bactivityconcentrationguidelines A given activity concentration guidance values, when the solid waste radioactivity concentration equal to or lower than this value, without the need for a case by case assessment Price, after approval by the regulatory authorities in the landfill to landfill disposal. 3.4 Close closure At the end of the landfill operation, the measures taken by the landfill, such as backfilling, the cover layer is set, so that the landfill be closed permanently. 3.5 Organized control institutionalcontrol Approved by the regulatory authorities of the landfill unit control, including monitoring, maintenance, anti-intrusion and land use restrictions. 4 low-level radioactive waste landfill principles 4.1 should be put under very low to ensure public and environmental safety of the premise, economic, rational disposal of waste.
