- Summary
- A structural analysis of a hexagonal fuel-element box under internal pressure is made, and the necessary equations to determine the maximum stresses and the total expansion of the box are derived. The results of the analysis indicate that the maximum stresses will occur in the box corner. These stresses are due primarily to the bending moment at the juncture of the corner and the box wall. The major contribution to the expansion of the box is due to thermal expansion. For an APM box with an internal pressure of 40 psi, 5.016 in. across the flats, at 700 deg F, having a wall thickness of 0.175 in. and a corner radius of 0.200 in.; the total box expansion, across the flats, is .052 in. (.042 in. due to thermal expansion). The maximum stress is 6250 psi. The results for the same box with corner radii varying from 0.10 to 0.25 in. and wall thickness varying from 0.150 to 0.205 in. are available from graphs of the stresses and expansions. (auth)
