适用范围：This International Standard is applicable to general aspects of system and component design,manufacturing and test methods for temperature sensors used in-core and for the primarycoolant circuit in nuclear power reactors.These sensors include thermocouples and RTDs (Resistance Temperature Detector–RTD).Emphasis is placed on the features specific to the nuclear application and recommendationsconcerning components and sensors are made only when they relate to the containment ofsuch components within the reactor primary envelope and/or in high radiation fields.The conditions imposed by reactor use are often different from those which occur in nonnuclearapplications. Parts of the in-core system may be located in very severe environments.Exposure to high neutron and gamma radiations is liable to cause error due to nucleartransformations, heating and structural changes, and to affect the mechanical and electricalproperties of the equipment so that extra care has to be taken in the standards adopted forinstallations and in the choice of materials.Furthermore, design consideration needs to be given to the effects of high environmentalpressure, high temperature, temperature gradients and temperature cycling as well as to theway in which the temperature measuring system could influence the safety or economicperformance of the reactor.The consequences of nuclear conditions for temperature sensors lead to strong requirementsregarding qualification.This standard deals with specific requirements for nuclear applications of temperaturesensors. It has two purposes:a) to provide a guide which will help to ensure that the reactor conditions do not damage thetemperature sensors;b) to ensure that the in-core temperature measuring system and the sensor installation donot prejudice the safe operation and the availability of the reactor.Statements of general applicability are made but detailed consideration is restricted tothermocouples and RTDs.
