Driver fuel-handling sequence

Fig. 5.5. FFTF driver fuel-handling sequence between interim decay storage and reactor vessel.

The reactor refueling system handles three types of core assemblies 12-ft assemblies, such as driver fuel 40-ft assemblies, such as fuels open test assemblies, which are loaded into the reactor full-length but are cut into two sections before removal and 40-ft assemblies, such as materials open-test assemblies, which are loaded into and removed from the reactor as full-length sections. The typical sequence for driver fuel-handling operation is summarized in Sect. A.2.1, and a brief description of contamination control and inventory control practices is provided in Sect. A.2.2. The FFTF refueling systems are more complex than those of a power reactor because the FFTF is a fuel testing machine that must handle many special test fuel assemblies, many of which require special handling.
