This report describes efforts to develop a safe, practical method to extinguish fires inside contaminated gloveboxes. Oil, trash, and metal fires were set to test various materials and techniques. Dry chemical extinguishers and MgO sand proved more practical than flooding the boxes with either CO/sub 2/ or argon. Gas replacement techniques pressurized the boxes and greatly increased the risk of outside contamination. 5 figs. (TEM)

It is necessary to provide the option of using either aluminum or zirconium tubes in the C pile 20-tube overbore test. A bumper-type fuel element has been designed to fit a fixed ribbed aluminum tube size; zirconium tube dimensions were then determined which will provide the same flow and pressure drop when the fuel element is changed from bumper type or self-supported without changing other fuel dimensions.

The objective of this supplement to Production Test IP-377-A is to evaluate the behavior of N Reactor inner fuel tubes with modified end closures during irradiation in the KER Loops. Natural and 0.947% enriched N Reactor inner fuel tubes (NINl and NIEl elements) with contoured end closures are authorized for irradiation in the KER Loops to exposures no greater than 2500 MWD/T. The modification consists of machining a V groove in the uranium after counterboring and using an end cap shaped to fit the groove. Both brazed and unbonded closures will be evaluated.

Progress is reported with respect to ZrH{sub x}-moderated thermionic reactors, thermionic fuel studies, EBR-II and OWR isothermal irradiator tests and tri-layer assembly development.

Abstract: "Fifteen in situ interval densities were calculated from the borehole gravity meter observations made in Test Well-B. The weighted average density for all the rocks sampled by the gravity meter is 1.83 gm/cc. The alluvium density ranges from 1.71 to 1.82 gm/cc and averages 1.76 gm/cc. The lake beds range from 1.91 to 1.93 gm/cc and average 1.92 gm/cc. The Rainier Mesa Member averages 1.83 gm/cc. The Tiva Canyon Member averages 1.74 gm/cc and the upper 110 feet of Topopah Spring Member has a density of 2.30 gm/cc."

Parameters determined by a least-squares method for the reduced Simon equation and for a new, empirical melting equation.

The United States Atomic Energy Commission authorized the production of 110 kg of U-233 by the irradiation of thorium oxide in the Hanford production reactors. This irradiation will be carried out by replacing the natural uranium fuel in all or a portion of the process tubes in several of the reactors with thorium oxide (thoria) and slightly enriched uranium. This reactor loading is referred to as an ``E-Q load.`` Reactor loadings are separated into two types which can be charged independently of each other: a mixed lattice in the central zone of the reactor in which enriched uranium (0.947 per cent uranium-235) and thoria are loaded in separate process tubes in uniform array with a fuel-to-target ratio of about 5.5--6.0 to 1 (core E-Q load), and a peripheral ring of thoria in the outermost process tubes of the reactor with the reactivity being supplied by enriched uranium (0.947 per cent uranium-235) in the process tubes in the immediately adjacent two lattice units (blanket E-Q load). This safety analysis is addressed to the core E-Q load; however, the specific fringe loading, with properly matched reactivity, has little effect on the basic physics and hydraulics of the reactor so the evaluation presented …

In the last two or three years there has been a notable improvement in the knowledge and understanding of reactor lattice physics. During this interval, measurements of parameters have been improved and the methods of analysis have been greatly strengthened. It has become apparent that the classical ways for computing the lattice parameters are not sufficient. It is the purpose of this report to publish under one cover as much of the most recent information as possible.
