Production of (Uranium) Tetrafluoride
Production of tetrafluoride for the month of April was 49,400. New equipment installed late in March operated smoothly and the production was slightly over the rated capacity of the plant. Nickel ends were welded on to the steel reactor tubes to prevent corrosion at the cover joint and possible contamination of the product with iron. The nickel ends will also save considerable repair work on the tube ends. The magnesium trays for some of the reactors are beginning to crack at the sides from frequent straightening. The trays are bent out of shape by the expansion of the product and are reshaped by hammering over a die. Some of the cracks have been repaired by welding but this is not very satisfactory because the welded trays are harder to straighten and often crack again.

Hanford Engineer Works technical manual
The uranium metal, as discharged from the piles in the 100 Areas, contains the alpha emitting product, plutonium, in concentration in the neighborhood of 150--250 grams per metric ton, along with similar amounts of beta and gamma fission elements. It is the purpose of the Separations Plant to effect the separation of this product from the uranium metal and fission elements, and to prepare a concentrated, relatively pure solution of plutonium nitrate as the final product of the Hanford Plant. This section of the manual discusses the chemistry of the separations process, describes the buildings and equipment provided for carrying out the various steps in the operation, and presents the detailed operating procedures used. There are included, in many instances, references to other documents presenting a more detailed view of a specific point in the process.

Interim report No. 2 on Production Test No. 105-17-P, Laboratory evaluation of proposed lubricants
The lubricant (Calel A-60) used to reduce pushing forces when discharging slugs from pile tubes forms a cloudy emulsion with water. During the initial period of operation at 100 B and D areas, spillage of lubricant during discharge produced so much cloudiness in the basin water that it interfered with sorting operations. An investigation was started to see if a lubricant could be found that would effectively lubricate tubes during discharge and which would form optically clear systems when mixed with water. This report presents the data on a number of lubricants which were suggested for test.

Turbidity coagulant for Columbia River water
In this document, information about the need for a better compound to for filtering process water from the production reactors. It was found that the natural turbidity in the Columbia River was high enough to necessitate the use of a coagulant to minimize the passage of iron through filters. Tests indicated that Ferrisul was the better of the two compounds tested.

Corrosion of Tuballoy-Molybdenum Alloys by Water
The primary purpose of the corrosion work was to find a tuballoy alloy which would be sufficiently corrosion resistant to be useful for canned slugs even if some of the can were to leak. The secondary purpose was to obtain general corrosion data on tuballoy alloys.
