Worth measurements of Eu$sub 2$$O$$sub 3$ and B$sub 4$C have been made at the location of a peripheral shim rod, of a control rod, and of a safety rod in the Engineering Mockup Critical (EMC) Assembly of the Fast Test Reactor (FTR). The worths were measured as a function of the volume fraction of control material in the rods over a range from 4 to 32 percent. The measurements indicate that europia is approximately equivalent to natural boron carbide on a reactivity worth per unit volume basis. Calculation of the worths and comparison with the experimental results have also been performed. (auth)
