Book Description

This report, GEMP-1004, is the seventh annual report on the unclassified portion of the GE-NMPO Fuels and Materials Development Program conducted during calendar year 1967 under Contract No. AT(40-1)-2847. This report covers eleven unclassified jobs: (1) properties of reactor materials from 1000 deg to 3000 deg C (2) radiation effects on the time-, temperature, and stress-dependent properties of fast breeder reactor (FBR) cladding and structural materials; (3) fabrication of FBR advanced fuel element cladding; (4) physical metallurgy of FBR cladding materials and refractory metals; (5) development of advanced FBR fuel element cladding materials with improved performance capability; (6) parameters affecting low-cycle fatigue behavior of heat-resistant alloys; (V) applicability of high strength steels to nuclear reactor pressure vessels; (8) behavior of Zircaloy-4-clad and Type 304 stainless steel-clad UO2 in meltdown environments; (9) high-temperature thermocouple and electrical materials; (10) physico-chemical stability and reactions between Fe-Cr-Al alloys and UO2; and (11) refractory carbides for fuel and structural applications.
