# UF Training Reactor

The reactor was built and began operation in 1959. [1] The core contains a number of pounds of low-enriched uranium. The power level is regulated by cadmium blades that act as a mechanical shim (analogous to control rods in a pressurized water reactor). The UFTR provides neutrons for the Neutron Activation Analysis Laboratory (NAAL), where samples undergo gamma spectroscopy. A flux of about $10^{12}$ $\frac{n}{cm^2 * s}$,thermal, activates the samples. The reactor performs neutron activation services for about $40 to$60 per sample, and is competitive to a number of alternative processes. The UFTR underwent a conversion to low-enriched uranium as a part of anti-terrorism initiatives in 2006.
