Unformatted text preview: and the radial displacement o f the outer surface o f the fuel has increased by 35 run. Consider two cases:  An uppower ramp from zero t o f u l l power i n 30 minutes;  An uppower r i i p from zero t o f u l l power i n 30 hours. 4. Calculational Basis  Use a single r i n g to represent the clad  Consider that the radial deflection a t the fuel outer surface and the clad average temperature vary l i n e a r l y with time during each uppower ramp.  Use only elastic, thermal, and creep strains. Let the creep strains equal zero a t hot zero power.  Use zero axial force from fuelclad contact. 5. Questions Obtain the following quantities upon reaching f u l l power i n each up power ramp: . ,  clad stress;  clad strain; and  r a d i a l displacement a t the clad outer surface....
