experimental campaigns are intended to support Generation IV nuclear power plant
design and for the qualification and development of CFD and STH codes. The facility
consists of a rectangular loop made of two vertical stainless steel (AISI 304) pipes of
2½ in. acting as riser and downcomer connected by means of two horizontal pipes of
the same dimension. The heat source (fuel bundle simulator) is installed in the bottom
part of the riser, while the upper part of the downcomer is connected, through appro-
priate flanges, to a heat exchanger (see Fig. 4.6). The heat source consists of two elec-
tric pins with a nominal thermal power of about 43kW and an active length of 0.89m.
