Which of the following factors is most critical in preventing fuel-cladding chemical interaction (FCCI) in advanced nuclear fuels?
Question 2
In the context of nuclear fuel assembly fabrication, what is the primary purpose of performing non-destructive examination (NDE) techniques such as eddy current testing on cladding tubes?
Question 3
Consider a $\text{UO}_2$ fuel pellet with an initial density of $95\%$ theoretical density (TD). If, during sintering, the pellet undergoes a linear shrinkage of $5\%$ in all dimensions, what is the approximate final density of the pellet as a percentage of TD?
Question 4
What is the primary technical challenge associated with the fabrication of thorium-based nuclear fuels compared to uranium-based fuels?
