Apparatus for determining the thermal history of equipment using solid state track recorders
Description
This patent describes a nuclear power plant having equipment subject to thermal aging, the rate of the thermal aging being capable of characterization by at least one equipment Arrhenius function of temperature, the equipment being subjected to a temperature environment having a predetermined range of temperatures, apparatus for determining the thermal aging which has occurred in the equipment. It comprises passive sensors, each of the sensors being formed from a selected material and subject to a thermal aging process within the range of temperatures, the extent of the thermal aging in each respective sensor being quantifiable, the rate at which the thermal aging process progresses in each of the sensors being characterized by a respective Arrhenius function of temperature; and the selected material not being the same for each of the sensors, whereby the range of activation energy values characterizing the respective Arrhenius functions encompasses the activation energy value characterizing the equipment Arrhenius function
