Expressions are derived for the first-order change in the fundamental eigenvalue of the neutron transport equation due to a perturbation in the boundary condition of the system. The perturbation formula is derived in the context of the energy-dependent transport theory and its diffusion approximation. Numerical examples are given in both transport and diffusion theory.
