For several years-after the start-up of the Hanford Piles, little concern was felt for the quality of process water. Techniques developed by CMX and improved in the course of operating experience were substantially successful for controlling and removing pressure drop film; and corru%ion rates at the early power levels were uniformly low and not a matter of concern, particularly since slugs were not exposed for more than 250 MWD/ton. As power and exposure levels were drastically increased, however, corrosion rates began to become serious and now threaten to limit future increases. Whether or not corrosion was causing these latter problems, it was clearly imperative to seek ways to reduce the corrobivity of the water. It was recognized that subtantial savings could be made by the elimination of sodium dichromate as a process water additive. Since the rather high pH of process water was neceasary primarily to prevent dichromate reduction, the way would then be open for reducing the pH, and it was hoped that this would improve in-pile corrosion and materially reduce water treatment costs. There is a large amount of data in the project literature pertaining to the dichromate problem, and it seemed urgent in view of recent experiences …

Report of the annual conference on weights and measures, hosted by the U.S. National Bureau of Standards in Washington D.C. It includes conference proceedings, a list of attendees, information about committees and officers, and other reports or commentaries discussed at the meetings.

Report presenting flight tests conducted on two different inlet configurations, a submerged divergent-wall inlet and scoop inlet, to determine their characteristics when installed on a YF-93 airplane. Measurements were made of the pressure-recovery characteristics of the inlets and overall airplane drag for each configuration. Results regarding the induction-system efficiency, airplane drag, and a relative comparison of the inlet installations are provided.

This report addresses the analysis of the sodium and water performance of the Atwood-Morrill swing check valve.

The cup assembly of the Experimental Breeder Reactor (EBR) consists of blanket bricks, inner rings, and safety plug, all of natural uranium. The design of the finish machined brick is shown in Figure 1. These pie shaped bricks when stacked together, 12 bricks arranged in circular form and stacked seven rings high, comprise the cylindrical portion of the outer blanket, 17.875" I.D. x 30.875" O.D. after machining and canning. The inner ring, which is shown in Figure 2, fits inside the bottom layer of bricks. The circular opening in the center of the inner ring is closed by the safety plug shown in Figure 3.
