The purpose of Production Test IP-603-I described in this report was to obtain data to help determine if uranium I&E fuel can be flused from tubes set up for discharge on a valved down corssheader by raising the front riser pressure. The test consisted of valving down one header at shutdown riser pressure, then increasing the riser pressure and recording the resulting front nozzle pressures on selected tubes uncapped on the rear. Test results and conclusions are presented.

Reference 1 gave mixer recommendations for aluminum spline tubes at the K reactors. On completion of the study, R. F. Corlett requested a more detailed economic study of mixer useage at KW reactor. R. G. Clough also requested additional information on use of mixer elements in fringe tubes. In order to answer these requests, additional information was needed and requested. A. W. Medcalf replied giving enriched metal requirements in support of mixers. No other information vas received so it was not possible to make the economic study requested by R. F. Corlett. This report presents more detail on tube-life estimates associated with use of the eccentric and concentric-wall tube designs in central- and fringe-zones and the results of five downstream thermcouple probes that operated in concentric-wall tubes at KW reactor. Also, modification of the concentric-wall tube (milling down of the ribs) is discussed.

A half-plant low alum water treatment test began at F Reactor on January 16, 1963. The test, which had been prompted by the analysis of ledge corrosion attack on fuel elements, will demonstrate whether or not high alum feed is responsible for increasing the frequency of ledge and groove corrosion attack on fuel element surfaces. The effect will be evaluated by comparing visual examination results obtained from the normal production fuel irradiated in process water treated with two different alum feed rates. Six 20-column fuel discharges, ten columns from each side of the reactor, have been taken during the test as follows: (1) One discharge prior to the start of the test. (2) One discharge such that the test side was exposed to coolant treated with both high and low alum feed. (3) Four discharges under test conditions. This report discusses the results obtained from the fifth discharge under test conditions.

This report discusses the review of the proposed thorium nitrate specifications,the preparation of tentative product specifications for Purex U-233 and thorium nitrates, and an estimation of the feasibility, cost and product composition for providing U-233 oxide at Hanford. The tentative specifications proposed for U-233 and thorium product for the Purex Plant are presented. The values chosen represent the understanding of feed material and reactor processing needs and the current estimates of Purex Plant capabilities.

Two changes have been incorporated in the tables of this draft: (1) The lithium-aluminum tonnages required for blanket and E-N loadings have been changed, (2) The production numbers for the small production reactors have been reduced per AEC direction, and a separate table is included for these numbers. Included data are power levels, operating efficiency, exposure, tonnage, conversion ratios, and annual production for the C, K, and small reactors.

Research and development progress is reported on analytical instrumentation, chemical analysis of advanced reactor fuels, analytical studies of molten-salt systems, special research problems, reactor projects, effects of radiation on analytical methods, x-ray and spectrochemical analyses, spectroscopy, optical and electron microscopy, nuclear and radiochemical analyses, inorganic preparations, organic preparations, and analytical development. Service analyses are also described. Separate abstracts were prepared for each topic. (M.C.G.)

A listing of the data on the revised tape is presented. The nuclear data are a reproduction of the computer printout. Other nuclear data (spectra, energy, absorption cross section of some poisons and absorption and fission cross sections of selected fuel materials) were transcribed from the tape listing to provide a more compact format or to allow easier comparison of absorbers and fuels.

From introduction: "In this paper, data obtained by Hunter and by the author are reported from laboratory investigations of (1) surge flow introduced into empty simply drains, (2) attenuation of surges in simple drains, (3) continuous full-section flow in simple drains under substantially steady, uniform conditions, (4) steady flow in compound drains, and (5) surge flow introduced through a branch drain into the side or top of a main drain carrying steady flow."
