3. NATURE OF PHYSICAL PROBLEM SOLVED

WELWING was developed to calculate the material buckling of reactor systems consisting of annular fuel elements in heavy water as moderator for various moderator to fuel ratios. The moderator to fuel ratio for the maximum material buckling for the particular system is selected automatically and the corresponding material buckling is calculated.

4. METHOD OF SOLUTION

The method used is an analytical solution of the one-group diffusion equations with various corrections and approximations.
