Title: PROGRAM FOR THE DEVELOPMENT OF PLUTONIUM RECYCLE FOR USE IN LIGHT WATER MODERATED REACTORS. Quarterly Progress Report, January 1-March 31, 1963

Technical Report ·
OSTI ID:4695329

The program fuel element was exposed to a burnup of 485 Mwd/t, which brings the total to 2334 Mwd/t, in the VBWR. Chemical and mass-spectrographic assays were completed on six radial samples and the pellet average sample extracted from a rod at an estimated burnup of 2000 Mwd/t. Cerium and cesium analyses indicated burnup of about 1880 Mwd/t. Autoradiographic and metallographic examination of the polished surface of the rod showed that the micro-segregation of the PuO/sub 2/ observed in the fabricated fuel was still present. Thermal average cross sections for all of the isotopes contained in the project fuel were computed by the THERMOS code. The epithermal cross sections and the fast-to-slow flux ratio were obtained from a MUFT-type calculation. (M.C.G.)
