Question 7 Critical Mass and Geometry (10)
a) Calculate the geometric buckling ($B_g^2$) for 1 m³ reactor with the following geometry -
(neglecting the extrapolation length).
1. Cubic
2. Cylindrical with height-to-diameter ratio 1:1
3. Spherical
For reactors composed of the same homogeneous material, which geometry in part a) has
the smallest critical mass, and which one has the largest and why?
