Experimental studies designed to fabricate NERVA graphite fuel elements capable of cyclic operations at exit gas temperatures of approximately 4400/degree/R were continued during this report period. Carbon precursor materials, manufacturing parameters, and deposition of carbide films are included in these studies. Accomplishments include the following: three commercial powders were extruded into elements having a desirable coefficient of thermal expansion; molded graphites using low-fired filler carbons and uncured short organic fibers produced graphites having an improved strain-to-failure value; thick-walled tubes of vapor-deposited zirconium carbide were produced, and the chemical composition was determined; vapor-deposited zirconium carbide coatings were applied to fuel-element bores; experimental graphite fuel elements were hot-gas tested; uranium-loaded ion exchange beads survived a heat treatment cycle of 2800/degree/C for three hours. Organic precursor carbon studies were oriented toward modification of the CAI polymers. 2 refs., 66 figs., 23 tabs.

An analytical solution for acoustic flaw triangulation on thin spherical shells has been prepared. A FORTRAN program is provided which takes as input the differences in the arrival times of acoustic energy at the transducers and evaluates the spherical coordinates of the flaw. Only three experimental time differences need be measured. For this measurement, four transducers are required. One transducer is placed at (R, 0, 0) in spherical coordinates; the other three are spaced 90 degrees apart around the equator.
