Question #1
(45%)
For future sodiumcooled reactors, uranium carbide may be used as fuel.
The fuel pin
will be of cylindrical geometry and housed in a stainless steel clad.
The dimensions as
well as the physical and mechanical properties of the fuel material and the clad are given
in Table 1.
1.1
What is the maximum linear hear generation rate (in kW/m) that the fuel
pin can operate at if the fuel is not to experience any fracture for r < 0.4R,
where R is the pellet radius? You may assume the pressure at the pellet
clad gap to be 0.3 MPa.
1.2
Does the clad design satisfy the ASME criteria for structural integrity
under static loads?
The fission gases will build up within the clad until the
