Summary
The first uranium specimens to be irradiated in the Ispra reactor wlll be contained in stainless steel cans each of which is placed in a second stainless steel can, with helium in the gap between the cans. In addition to the fission heat ing the specimens are electrically heated to achieve temperature control. Aluminum spacers are used to vary the width of the helium gap, thus altering the heat transfer conditions in the cans. The thickness of the spacers is chosen to give the required specimen temperature with the power available from the heater. The suggested thicknesses of the helium gaps are: 0.002 in. to maintain the specimens at 200 deg or 200 deg plus or minus 50 deg C; and 0.050 in. to maintain the specimens at 550 deg or 500 deg plus or minus 50 deg C.
