摘要

Pile temperature control is normally maintained by using four horizontal rods, two ''long'' rods extending to the far side of the pile and two ''short'' rods whose tips are on the near side. (1) This procedure prevents cycling of ''hot spots'' about the pile, but does not achieve symmetrical horizontal temperature distribution. Prior to pile operation the cadmium-containing cans were removed from the near ends of the two ''long'' control rods, numbers 5 and 11, at C pile, so that when these rods were in the ''full in'' position their poisoning effect outside the flattened region at the near side of the pile would be small. By using these ''half rods'' in conjunction with ''short'' rods it was expected that a nearly symmetrical horizontal temperature distribution could be maintained. A comparison of near-to- far temperature distribution at C-pile with other piles indicates that gains in production of 4% during early operation of a pile and 3% during later equilibrium operation can be realized by using the half-rods. On the basis of these observations ''half-rods'' are to be incorporated in the K-piles currently under construction. It is recommended that the ''long'' control rods in existing piles be replaced by rods altered in an equivalent manner. (ERA citation 18:008846)
