Harlow, R A; Wagner, R K

A literature survey was made to investigate the properties of the low cross-section materials that are being considered for pressure tube applications in the GBSR. Physical snd mechanical properties of beryllium and two zirconium alloys, zircaloy 2 and 321, showed that these materials exhibit useful elevated temperature strength for the intended application, but their corrosion rates may impose limitations on the use of either material. A second disadvantage of beryllium is its extremely low ductility which decreases on irradiation. For preliminary design, allowable stress levels of 10,000 psi at 600 deg F and 8000 psi at 700 deg F are suggested for the zirconium alloys, zircaloy 4. (auth)
