From abstract: "The present paper proposes a lattice test pile, (or LTP) as an alternate to the continuing program of building up and tearing down of exponential piles."

From introduction: "The discovery of element number 96, curium, was realized by the preparation and identification of the isotope Cm-242 by G. T. Seaborg, R. A. James and A. Ghiorso by cyclotron bombardment of Pu-239 with helium ions."

The following report is focused on finding the measurements of low temperature heat capacities of neptunium dioxide. The entropy and the interpretation of the anomaly in the heat capacity curve will be dicussed."

This report follows experiments on K[infinity], measuring the element for several red sizes, enrichments, and water-to-uranium volume ratios-(1, 2), by making use of the relation k[infinity] = 0M-[2]B-[2] (M-2 = migration area, B = buckling). The purpose of this report is to compare the experimental data for k[infinity] with values calculated from the four-factor formula k[infinity] = [eta][epsilon]pf.

"The purpose of this specification is to describe a procedure for preparation of pure BF3 gas, suitable for use in BF3 proportional neutron counters."

The development of the reactor layout is continuing. New features that have been incorporated because of stress, fluid flow, or fabricability considerations include an elliptical fuel expansion tank, a rounded dome to enclose the top of the reactor, a newly designed sodium pump impeller, and other related items. Recently completed heat exchanger tests yielded consistent data from which a series of heat exchangers is being designed. The most promising of these will be chosen for the ART.

A laboratory scale test was devised to determine the relative physical stability of ion exchange resins designed for use in the resin-in-pulp process. The test was applied to four samples of resins.
