Nuclear power plants - Instrumentation important to safety - Temperature sensors (in-core and primary coolant circuit) - Characteristics and test methods

IEC 60737:2010 deals with specific requirements for nuclear applications of temperature sensors. It provides guidance which will help to ensure that the reactor conditions do not damage the temperature sensors; it ensures that the in-core temperature measuring system and the sensor installation do not prejudice the safe operation and the availability of the reactor. Is applicable to general aspects of system and component design, manufacturing and test methods for temperature sensors used in-core and for the primary coolant circuit in nuclear power reactors. The main changes with respect to the previous edition are the following additions:

- descriptions of the comparative performance of thermocouples and resistance temperature detectors;

- discussion of the temperature measuring system requirements for reactors.
