POISON ROD REQUIREMENTS FOR A SOLID-FUEL LEACHER TANK
Estimates were made of the amount of neutron poisoning, in the form of boron rods, required to maintain suberiticality in a tank used for dissolution of solid fuel elements. The tank under consideration was a cylinder 19.5 inches in diameter and 6 ft in height. Maximum concertrations of fuel and fertile material resulting from dissolution of various type fuel elements sre tabulated. Below the maximum concentrations listed, it was found that the limiting poisoning requirements are associated with dissolution of the NS Savannah elements. About five 1-inch diameter rods appear necessary: a centrally located rod and four rods in a square array each about 5 inches from the central rod. (auth)
