Thermal Shock
DOE-HDBK-1017/2-93
OBJECTIVES
TERMINAL OBJECTIVE
1.0
Without references, DESCRIBE the importance of minimizing thermal shock (stress).
ENABLING OBJECTIVES
1.1
IDENTIFY the two stresses that are the result of thermal shock (stress) to plant materials.
1.2
STATE the two causes of thermal shock.
1.3
Given the material’s coefficient of Linear Thermal Expansion, CALCULATE the thermal
shock (stress) on a material using Hooke’s Law.
1.4
DESCRIBE why thermal shock is a major concern in reactor systems when rapidly
heating or cooling a thick-walled vessel.
1.5
LIST the three operational limits that are specifically intended to reduce the severity of
thermal shock.
1.6
DEFINE the term pressurized thermal shock.
1.7
STATE how the pressure in a closed system effects the severity of thermal shock.
1.8
LIST the four plant transients that have the greatest potential for causing thermal shock.
1.9
STATE the three locations in a reactor system that are of primary concern for thermal
shock.
