It provides the opinion of the Texas Attorney General, Waggoner Carr, regarding a legal question submitted for clarification: Whether, under the stated facts, the Texas State Board of Registration for Professional Engineers has the authority to re-open an application for registration under Section 18 of Article 3271a that was rejected 26 years ago.

A study was initiated in the Pile Physics Unit to evaluate current methods for prediction of xenon behavior in light of newer operating conditions, and thus possibly improve the critical prediction accuracy. Particular areas considered included: (1) validation and limitations of the flux-squared weighting technique for homogenizing localized xenon effects, (ii) effect of elevated graphite temperature on xenon poisoning, (iii) xenon poisoning in the dry lattice, (iv) xenon-control rod interaction and mutual shadowing, and (v) effects of moderate to severe flux distortions. This document comprises the result of that study.

This document presents laboratory data pertaining to the heat-transfer and fluid-flow conditions within a K Reactor process channel using self-supported fuel and a ribless Zircaloy coolant tube. Data are included to show the steady-state hydraulic-demand characteristics during normal conditions and during conditions which simulate a slow flow reduction by plugging upstream of the Panellit pressure tap.

Hot die sizing (HDS) is a process being investigated to replace the existing AlSi brazing process. Hot die sizing consists of sizing a nickel-plated core and aluminum can assembly with cold dies to produce a diffusion bonded aluminum clad fuel element. Upon completion of fabrication of the first natural uranium hot die sized fuel elements for production test IP-546-A, the next step in evaluation of the process was to assemble enriched fuel for further irradiation testing. This report summarizes the fabrication of 0.947% U-235 enriched fuel elements for ``Production Test IP-616-A.``

From Introduction: "The purpose of the paper is to discuss the assumptions and the reasoning by which the calculations described in the Engineering Manual were derived from the data in [1]. The relevant curves from [1] are given in Appendix A and the technical charts from the Engineering Manual are given in appendix B."

Uranium carbide shows promise as a fuel material for reactors operating at relatively high temperatures based on its high melting point, high uranium density and high thermal conductivity. Before refined reactor designs can be made, however, good quantitative data on the thermal conductivity at temperatures in excess of 1000C is required. This technical report presents data gathered as part of a continuing study aimed at determining the thermal conductivity of refractory uranium fuels as a function of temperature, density and composition over the temperature range 1000-2200C. At the inception of this program it was felt that an absolute method capable of achieving high temperatures was necessary and that the difficulties encountered in fabricating the large complex specimens needed were justified. The steady state radial heat flow method and apparatus of Rasor and McClelland were therefore chosen. The technical report discusses the experimental equipment and presents results of measurements on three specimens of UC over a temperature range 900 to 1600C. An analysis of the data is made with respect to other physical properties of the material and the measured conductivities are compared with the work of other investigators.
