APPLICATION OF VARIATIONAL PRINCIPLES TO THE CALCULATION OF CRITICAL SIZES
Technical Report

OSTI ID:4268742
Variational principles are given for one- and twogroup diffusion theory for bare and reflected reactors. A variational principle is also given for the albedo method of calculating critical sizes of small fast systems with moderating reflectors. These principles can be used directly to give reasonably close upper and lower bounds for critical size, or they can be used with either the Rayleigh-Ritz procedure or the methods of optimized parameters and optimized coefficients to obtain more accurate upper bounds.
