The following report describes results from a study of three types of cement (Barytes, Brookhaven, and Portland) exposed in the ORNL Reactor for periods of seven and twenty-eight days.

Technical report. From Abstract : "Magnetic moment measurements have been made on single crystals of terbium (hcp) with fields of 50 to 18,000 oe applied along the <1120> (a-axis), <1010> (b-axis), and <0001> (c-axis) directions. The temperature range covered was 1.4 to 500°K."

The reaction of alanine-1-C14 and phenylalanine-1-C14 with acetic anhydride in the presence of pyridine has been studied and the carboxyl group of the amino acid has been shown to be the exclusive source of carbon dioxide involved.

From abstract: "The distribution of carrier-free thorium, protoactinium and neptunium in the rat following intramuscular and oral administration has been studied. Oral adsorption for all three is negligible. Following parenteral administration, the skeleton is the organ showing the highest degree of prolonged and selective localization."

Document HW-33176, "A Proposed Scope of the 100-K Sulfuric Acid Addition Facilities", presented the justification and bases for a sulfuric acid addition facility at the 183-K headhouses and included a system for adding the acid to the raw water. Since the issue of this document several factors to consider in such a system have been brought to light by experience gained both at K and at other areas. The alternate system presented here eliminates several of the troublesome points in the previously proposed system.
