What Is “Spiking?”

During the trial burn, known quantities of the test materials are pumped into the hot end of the incinerator in one of two ways: either as a “native”  species (something that is already present at a known concentration in the waste fuel); or as an additive that is injected at a carefully controlled rate into the waste fuel or directly into the incinerator.  This additive injection process is called “spiking.”
