These tests were performed in accordance with a letter fran R. C. Breisch to J. R. Spink, May 7, 1962. An unrestrained gunbarrel condition was simulated for each of the standard process tube inlet assemblies for B,C and K type reactors. Primary objects of the testing were to obtain data on movement, pigtail damage, and effect on flow to the process tube in case of a Van Stone flange failure without key restraint of the gunbarrel. All test conditions were relative to actual conditions, but these conditions were not necessarily typical or maximum. The gunbarrels were not loaded with do-nuts or thermal shield pieces. All of the assemblies moved instantly and rapidly when released under pressure. The B and K braided type pigtails crimped just upstream of the ferrule on the nozzle connection. The helical tube C-type pigtail stretched about six inches, but did not travel far enough to cause flow restriction. Tube flow for the B case was 54 per cent of that prior to Van Stone flange failure. For the K test, the flow was reduced to 69 per cent of that prior to Van Stone flange failure.

The initial fuel landing for the N-Reactor and the use of a specific alternative fuel element are described in a previous report. It is highly probable that it will also be desirable in the future to irradiate still other types of fuel elements in the reactor. If the test is of small scale, fever than five channels, or if these elements vary only slightly from the initial fuel load (or any other fuel type approved for large-scale use at some future date), the irradiation will be accomplished within the normal administrative procedures and controls established for the Production Testing Program. In this context, in-reactor testing of minor changes in the fuel cladding alloy, alternate methods of affixing end closures, different fuel support designs or similar changes are considered to be within the scope of normal productiontesting. It is possible, however, that it will be desirable to irradiate test fuel elements which are significantly different from any element approved for general use and in quantities of greater than five fuel columns at a given time. A more formalized review of such tests including approval by the AEC would appear appropriate in these instances. The purpose of this document is to outline …

The monthly report for the Hanford Laboratories Operation, May 1963. Reactor fuels, chemistry, dosimetry, separation processes, reactor technology, financial activities, biology operation, and physics and instrumentation research, and applied mathematics, and programming operation are discussed.

Hanford`s potential has been evaluated for producing higher transuranic isotopes, particularly curium-242 and curium-244. This document outlines the concepts visualized, and estimates the potential impact on CPD`s development, construction, and production programs. The irradiation program would proceed in 3 steps: production of fuel-grade plutonium, its burning to higher isotopes and alloying with Al for use in one reactor, and the separated americium irradiated to form curium-242. Disposition of higher Pu isotopes and alternative production of curium-244 are discussed.

Volatile compounds containing C{sup 14} produced in the cooling gas systems of Hanford reactors can be lost from the cooling gas by two routes. These are (a) escape via the reactor stacks through leaks in the cooling gas system and (b), adsorption with water vapor on the silica gel of the dryers for the cooling gas with subsequent regeneration of the silica gel and condensation of the water for disposal. Information relative to the release rates by the stack gas route was reported in HW-75618. The present report provides data relative to the C{sup 14} loss rates through the condensate obtained from regeneration of the silica gel dryers of the reactor gas cooling systems. The C{sup 14} containing compounds in the reactor gas are produced by n,{gamma} reaction on the nitrogen in the coolant gas, an n,{gamma} reaction on carbon in the CO{sub 2} component of the coolant gas, or an n,{gamma} reaction on the graphite moderator with subsequent volatilization. Studies are presently under way to determine the contribution of graphite ``burnout`` to the C{sup 14} containing volatile compounds in the coolant gas. Upon completion of these studies a topical formal report will be Issued which will include the findings …

At your request the Plant pressure monitor scram history for the period covering January 1, 1960, through June 31, 1963, was reviewed to predict the production saving that would result if a reliable pressure monitor dual-trip feature were added to the six old reactors.

Presently, there is no standard technique in use by all assigned physicists to actually calculate required reactor loading changes. Basically, loading changes are made by determining the number of enrichment columns needed for equilibrium operation following startup; this is usually based upon past experience with relatively similar reactor conditions. Selection of locations for placement or removal of the enrichment then involves the application of information gleaned from temperature maps, previous experience, educated guesses, or a combination of the three. The program is based on one-group, one-dimensional, diffusion theory. Local buckling effects caused by fission products, temperatures, and materials are calculated for many small zones of the reactor before and after a discharge. Loading changes are then designed to produce a central zone buckling of zero with the required supporting buckling of the enrichment ring; equal bucklings for all zones within a particular region are achieved by manipulation of the enrichment inventory in each particular zone. This program is primarily designed for specific use by assigned physicists of the Pile Physics unit. Basic familiarity with the standard calculational techniques, nomenclature, and technical jargon of that group is necessary for effective application. Program input includes region geometry and material, plus reactivity variables; …

Abstract The phase diagram of the uranium-rhenium alloy system is presented along with a discussion on transformation kinetics of the uranium solid solutions. The phase diagram is of the double eutectic type with the intermediate phase having the composition URe2. This phase exhibits allotropy at 180°C and melts congruently at 2200°C. URe2 reacts sluggishly with the uranium solid solutions below 750°C to form the peritectoid compound U2Re. Eutectic reactions occur at 1105° and 2105°C at respective compositions of 10.5 and 65.5 wt. % Re. Eutectoid reactions occur at 643° and 681°C at compositions of 1.4 and 6 wt. % Re, respectively. The maximum solubility of rhenium in α uranium is about 0.4 wt. % at 643°C and in β uranium is 1.9 wt. % at 681°C. The solubility of rhenium in γ uranium is 6 wt. % at 681°C and increases to about 7 wt. % at 975°C. The solubility of uranium in rhenium is 0.6 wt. % at room temperature with little variation up to 2000°C. Alloys of β and γ uranium containing more than about 1.2 and 7 wt. % Re respectively, can be readily supercooled to room temperature. Rapid cooling of γ alloys containing less than about …

Feed stock prepared from ingot, dingot, and under-saltmelted U was melted by electron bombardment. Analysis of the ingots produced revealed that some Al, Cr, Mg, Mn, and Pb were volatilized from the melt. C was reduced when Zr was present in the feed material. H/sub 2/ and N/sub 2/ also were removed, the latter oniy when there was a relatively high concentration in the feed material. The work indicated the need for very slow melting rates or the casting of large diameter ingots for successful refinement of U. (auth)
