Date :Définition
The change in reactor reactivity (per degree of temperature) occurring when the operating temperature changes.
Note :
The coefficient is said to be positive when an increase in temperature increases the reactivity, and negative when an increase in temperature decreases reactivity. Negative temperature coefficients are desirable because they held to prevent power excursions.
