Accident conditions of PWR nuclear power plant Nuclear island building Radiation Protection Design Guidelines1 ScopeThis document specifies the radiation protection design, equipment and instruments for the safety radiation protection of nuclear island building staff in pressurized water reactor nuclear power plants under accident conditions. Principles, methods and assumptions to be followed in terms of radiation environment requirements, radiation partitions under accident conditions, and monitoring instrument thresholds. This document is applicable to the radiation protection design of the nuclear island building under the accident condition of the pressurized water reactor nuclear power plant, and other reactor types shall be implemented by reference.2 Normative referencesThe contents of the following documents constitute the essential provisions of this document through normative references in the text. Among them, dated references For documents, only the version corresponding to the date is applicable to this document; for undated reference documents, the latest version (including all amendments) is applicable to this document. GB 18871-2002 Basic standards for protection against ionizing radiation and safety of radiation sources3 Terms and DefinitionsThe following terms and definitions apply to this document. 3.1 accident condition Deviation from normal operation, a condition in which the frequency of occurrence of operational events is less than expected but more serious. Note. Accident conditions include design basis accidents and design extension conditions. Design extension conditions include conditions without significant core damage and core meltdown (severe accident) conditions. 3.2 design basis accident designbasisaccident A hypothetical accident leading to accident conditions in a nuclear power plant. Note 1.The release of radioactive material in these accidents is within the specified limits, and the nuclear power plant is designed according to established design criteria and conservative methods. Note 2.According to the frequency of accidents, design basis accidents are divided into two types. rare accidents and extreme accidents. 3.3 serious accident severe accident Accident conditions whose severity exceeds the design basis accident and causes significant deterioration of the core. 3.4 Under accident conditions, in order to complete the emergency response tasks, the staff need to enter or stay in the key areas with high radiation levels in the plant. area. Note. The radiation protection design of key areas meets all relevant requirements to ensure the radiation safety of personnel in completing emergency tasks. 3.5 Under accident conditions, the dose rate level of the environment where the equipment and instruments are located, and the cumulative radiation received during the time limit for performing safety functions ......Tips & Frequently Asked Questions:Question 1: How long will the true-PDF of GB/T 42141-2022_English be delivered?Answer: Upon your order, we will start to translate GB/T 42141-2022_English as soon as possible, and keep you informed of the progress.
