✦ Synopsis

The thermal utilization factor is calculated in diffusion approximation for a lattice of thick cylindrical fuel elements. It is shown that if the lattice is of sufficient symmetry (i.e. if identical fuel elements are placed at the vertices of a regular hexagon, square or equilateral triangle) the use of the equivalent cell method gives a good approximation even if the elements are close-packed. The solution is stated in a form which permits the introduction of non-diffusion corrections.
