The following report describes methods used to determine tributylphosphate in a deodorized shell base. An infrared absorption method is developed to emphasize toward determination of TBP in RCW streams, the organic waste streams.

The conservative design criteria applied to process tubing may seriously hinder the advancement of high temperature reactor development. Factors of safety of 3 to 4 applied to an arbitrarily defined yield strength are used to calculate allowable internal working pressures. The effect of biaxial stressing on the tubes has been shown (2) to cause yielding at a lower internal pressure. However, tests conducted on biaxially stressed short lengths of tubing indicated that the ultimate tensile strength of the material was not affected.

Powder metallurgy is rapidly gaining importance as a means of fabricating nuclear fuel elements and other reactor components. It provides a convenient method for forming metals, unusual combinations of metals, and metal-ceramic combinations. The unique features of this technique which make it desirable for nuclear engineering purposes are the following:
