QUARTERLY STATUS REPORT ON LAMPRE PROGRAM FOR PERIOD ENDING FEBRUARY 20, 1963
Operation of LAMPRE I is summarized, and predictions of power and temperature transients by a new Fortran code (LTC) are compared favorably with experimental results. LAMPRE fuel capsules were metallographically examined and revealed Na attack of weld metal surfaces as well as intergranular penetration of Pu-fuel in the heataffected zone of the welds. New techniques were developed for fabricating capsules. Several alloys were investigated. Corrosion tests of Ce-- Co--Pu alloys in Ta showed an increase in C content to reduce Ta/sub 6/Co/sub 7/ layer formation. High Co contents in Ce-- Co alloy produced an increased Co- Ta film growth. Tests on yttrium capsules containing Mn--U and Mn-- Pu--U alloys showed the Pu to increase the corrosion resistance of Y to Mn--U fuels. Methods for fabricating and preparing plutonium alloys were developed. Status of the core test facility is reported. Several Pu alloy systems were also examined, mainly to gain information on phase relations in Pu alloys. Decomposition, lattice parameters, solubility, phase diagrams, and formation reactions were among the examined properties of the C-O--Pu, Eu--Pu, La-- Pu, N-- Pu, Pr--Pu, Pu- Sc, and Pu--Y systems treated.
