Thermal Stress:

Thermal stresses arise in materials while they are cooled or heated.   Thermal stresses effect the operation of facilities, both since of the huge parts subject to stress and since they are affected through the way in that the plant is operated. This lesson defines the concerns related along with thermal stress.

IDENTIFY the two stresses which is the result of thermal shock (stress) to plant materials.

STATE the two causes of thermal stresses.

Given the material's coefficient of Linear Thermal Expansion and CALCULATE the thermal stress on a material using Hooke's Law.

DESCRIBE why thermal stress is a main concern in reactor systems while rapidly cooling or heating a thick -walled vessel.

LISTS the three operational limits which are specifically intended to decrease the severity of thermal shock.
