An intra cell neutron flux traverse has been done in the BNL reactor by the Reactor Physics group, to measure thermal utilization. A special uranium fuel element was constructed with provision for containing 25 dysprosium foils internally and 12 dysprosium foils on the aluminum fins. The fuel element was 3 feet long and was constructed of the same materials which are normally used in the reactor fuel elements and was loaded into fuel channel A-9-6. A special graphite cartridge, 2.6" diameter and 2 feet long, was loaded into newsom hole A-9-6 1/2. Dysprosium foils were embedded in the graphite cartridge opposite the foils in the special fuel element. The distribution of dysprosium foils permitted a measurement of neutron flux in the uranium, on the aluminum fins, and in the graphite midway between nearest fuel rods.
