1 Scope This standard specifies the basic requirements for staff radiation protection during the operation of nuclear power plants. This standard is applicable to the debugging, operation, examination, test and maintenance of land water-cooled reactor nuclear power plants after being loaded with nuclear fuel, the production activities like nuclear power plant reconstruction and radioactive waste management as well as exposure control on the staff members of nuclear power plants during nuclear accident emergency response. It is also applies to the location, design, construction and decommissioning of nuclear power plants. 2 Normative References The following normative documents contain provision which, through reference in this text, constitute provisions of this professional standard. For dated reference, subsequent amendments to, or revisions of, any of these publications do not apply. For undated references, the latest edition of the normative document referred to applies. GB 18871-2002 Basic Standards for Protection against Ionizing Radiation and for the Safety of Radiation Sources 3 Terms and Definitions The terms and definitions in GB 18871-2002 and the following ones are applicable to this standard. 3.1 Operating organization The organizations with license issued by the national nuclear safety department and in charge of the management and operation of nuclear power plant. 3.2 Contractor The organization providing services for nuclear power plants in the form of contract. 3.3 Quality assurance The systematized activities to ensure all items or services to meet the specified quality requirements and to provide all necessary plans for adequate confidence. The so-called "items" is the generic term for material, parts, components, equipment, system, structure and computer software. 3.4 Work management A kind of multi-professional and overall-process management mode, which emphasizes team work and overall-process management, including planning, preparing, implementing and tracking to fulfill the tasks. 3.5 Radiation work permit The written documents for nuclear power plants to examine and approve the operation, maintenance, examination, test and other activities that need any special radiation protection measure. 3.6 Hot spot In such small or local areas where the radiation level is far higher than that in surrounding environment, the hot spot is usually formed by hot particle with extremely high radiation level. Those hot particles are generally tiny particles in reactor coolant with small size and strong activity. 3.7 Fitness assessment The assessment of the staff's fitness or continuous fitness with anticipated or present job, made by professional physician with required qualification based on the results of health examination. 4 General Provisions 4.1 To ensure the radiation safety of staff in nuclear power plants as well as to prevent and avoid harmful radiation effect, the operating organization of nuclear power plants shall formulate and implement radiation protection outlines according to the relevant regulations and standards as well as its own actual situation. 4.2 As for the debugging of nuclear power plants after being loaded with nuclear fuel, the operation, examination, test and maintenance under normal operation condition and the production activities like nuclear power plant reconstruction and radioactive waste management, it shall meet the requirements of practical radiation protection in GB 18871-2002, namely practice justification, dose limit and optimization; during accident handling and emergency response, the operating organization shall do best to prevent deterministic health effects and follow the requirements of intervence justifiability and optimization. 4.3 The radiation protection outline of nuclear power plant shall be based on the relevant standard of radiation protection and radiation source safety and shall follow the safety policy of the operating organization to determine the guideline and target of radiation protection as well as the responsibility of parties concerned, to specify occupational exposure control and to meet the specific requirements of radiation protection optimization. 4.4 As for all staff, including contractors in nuclear power plants that is involved in radiation exposure or may be involved in radiation exposure, they shall know about, follow and implement the regulation and requirements of the radiation protection outline. 5 Organization and Responsibility of Radiation Protection 5.1 To control occupational exposure and optimize radiation protection, the operating organization of nuclear power plant shall establish radiation protection organization system for implementing the radiation protection outline. The radiation protection department shall be independent of the department for production activities, such as operation and maintenance. 5.2 The operating organization of nuclear power plant shall:
