Under what conditions would negative buckling (B^2) be possible?
Negative Buckling: What Are the Conditions?
Click For Summary
SUMMARY
Negative buckling (B^2) is impossible under any physical parameters, including sphere radius, reaction cross-sections, and diffusion coefficients, which cannot be negative. The discussion clarifies that mechanical buckling differs from neutron flux buckling in nuclear reactors. Specifically, a negative B2 indicates a subscritical system, defined mathematically as B2 = (νΣf - Σa)/D = (k∞ - 1)/L2, where negative buckling occurs if k∞ < 1 or Σa > νΣf. Geometric buckling cannot be negative.
