Intervention level of emergency operation of nuclear power plant1 ScopeThis document specifies the methodology for establishing and correcting operational intervention levels under reactor emergency conditions. This document applies to pressurized water reactors, other types of reactors can also be used for reference.2 Normative referencesThe contents of the following documents constitute essential provisions of this document through normative references in the text. Among them, dated citations documents, only the version corresponding to that date applies to this document; for undated references, the latest edition (including all amendments) applies to this document. GB 18871-2002 Basic standard for ionizing radiation protection and radiation source safety3 Terms and DefinitionsThe following terms and definitions apply to this document. 3.1 interventionlevel The preventable dose level established for an emergency exposure situation or a continuous exposure situation. NOTE. When reaching this preventable dose level, consider taking appropriate protective or remedial actions. [Source. GB 18871-2002, J6.10, with modifications] 3.2 actionlevel In the case of continuous exposure or emergency exposure, the dose level or activity concentration level at which remedial action or protective action is taken into account. [Source. GB 18871-2002, J6.11, with modifications] 3.3 The value derived from the corresponding generic intervention level or generic action level. NOTE. Operational intervention levels are quantities that can be directly compared with instrumental measurements or laboratory analyses, such as ambient dose equivalents in radioactive plumes rate, radionuclide concentration, etc. 3.4 Preventable dose of averagedose The dose reduced by taking protective action, that is, the dose expected to be received if protective action is taken and the dose not taking protective action The difference between the doses expected to be received under the circumstances. [Source. GB 18871-2002, J6.9] 3.5 covert sheltering Emergency protection measures for personnel staying (or entering) indoors, closing doors, windows and ventilation systems. ...... |
