Rationale

A new standard is needed because many standards relevant to the nuclear industry specify that the temperature of an experiment or surveillance capsule must be known, but leave the calculation of the temperature in an irradiation environment as extrapolation of coolant temperature or measurement of the maximum irradiation temperature as interpreted by melt wires. Many properties of irradiated materials depend on the temperature the material experienced within the radiation environment. In many test reactors or light water reactors, the neutron flux and energy spectrums are well understood and monitored. However, the irradiation temperature is more difficult to determine. This standard will be used by those who wish to determine a time-averaged temperature within a radiation environment in the location of a silicon carbide passive temperature monitor. The users are anticipated to be those in the nuclear industry supporting surveillance capsule testing, laboratory facilities using test reactors for materials irradiations, and the academic community interested in studying the fundamental science of how materials evolve with radiation and temperature.
