This report discusses legislative history of the adult education act. It reviews the reported with amendments, senate Rept . No. 1218, supplement senate report no.1218, and debate in senate.

Research and development activities on advanced (alternatives to glass) nuclear waste forms are reported. The emphasis is on two phases of the work to give essential background information on supercalcine development. The first is a report of the data obtained in the study of cesium aluminosilicate for Cs and Ru fixation. Research on the compatibility of the phases formed in the complex oxide system made up of waste and additive cations is reported. The phase stability in a number of proposed formulations was determined. (JSR)

An interactive program, ALLCAL, has been developed at Los Alamos Scientific Laboratory (LASL) to calculate the results of spectrochemical measurements of impurities in production samples. The program generates a working curve from input data of standard samples to calculate the impurity concentrations. ALLCAL permits use by individuals with minimal programming experience/ it is truly interactive in providing periodic means to edit, modify, and change incorrect data that might have been introduced through various human error factors affecting any computer program, without the need to terminate and reinitialize after such editing. The program can be used as a research tool to manipulate data with minimum effort and eliminates repetitive input data from its operation. It also provides the spectroscopist a comparison mode to evaluate the effect of the use or nonuse of a given internal standard. ALLCAL accepts either optical density or percent transmittance data from photographic plates and films. The program is written in BASIC language for a minicomputer with 28,000 octal words of core memory and has been shown to be adaptable to another computer system with slight modifications. (auth)

This report is about the state-of-the-art of the anaerobic fermentation processes for the conversion of cellulosic waste materials to chemicals and fuels.

A post-accident-heat-removal structural effects analysis for the steel liner in the FFTF concrete containment structure is presented. (JWR)

This report is an analysis of cost factors of 1974 coal prices.

All suitable measurements of the energy dependence of (n,2n) cross sections of all isotopes up to mass 238 have been analyzed. The objectives were to display the quality of the measured data for each isotope and to examine the systematic dependence of the (n,2n) cross section upon N, Z, and A. Graphs and tables are presented of the ratio of the asymptotic (n,2n) and nonelastic cross section to the neutron-asymmetry parameter (N--Z)/A. Similar data are presented for the derived nuclear temperature, T, and level-density parameter, $alpha$, as a function of N, Z, and A. This analysis of the results of over 145 experiments on 61 isotopes is essentially a complete review of the current status of (n,2n) cross-section measurements. (auth)

A new computer program, SOLA-OF, has been written to solve the unsteady, two-dimensional equations of motion for a two-phase mixture. The equations solved are based on the drift-flux approximation and include a phase transition model and a general drift velocity calculation. The SOLA-DF code is used for a study of the blowdown of straight pipes initially filled with water at high temperature and pressure. Computed results are presented that show the relative importance of phase transition rates, pipe friction, drift velocity magnitude, and other model variations. The computed results are also compared with experimental data. 7 references. (auth)

Development work on the study of consolidation techniques for Zircaloy fuel-cladding hulls included scouting tests on volatility schemes for separating the zirconium as the volatile tetrachloride and ignition tests on several Zircaloy materials to further characterize the pyrophoric behavior of Zircaloy. All tests were with nonirradiated metal pending acquisition of irradiated samples. Installation is nearly complete of a glovebox facility for studies on the salvage of alpha-contaminated metals by pyrochemical methods. Disposal of a major portion of fission product tritium formed in light water reactor fuels by deep- well injection of the low-level aqueous waste from plants reprocessing such fuels is being evaluated. The question of siting is a very important factor in determining the feasibility of this particular disposal option. A review is given of the status of information for U. S. sedimentary basins, the areas most likely to be generally suitable for siting of waste wells. Work on the reliability of high-level-waste canisters included an examination of creep, shot- peening, and subcooling of the filler canister below storage temperatures, as methods of relieving stresses induced in canisters due to differential contraction of canister and glass during cooling. A method was investigated for relieving stresses in calcine-filled canisters. Properties …

The Ta--Hf phase diagram was found to be sensitive to carbon content, even at levels low enough to prevent carbide formation. The ..beta../..cap alpha.. solvus at 1200/sup 0/C went from 27 to 7 percent Hf as the soluble carbon concentration increased. This effect was seen in aged and carburized samples. Just below the carbide-containing subscale, the dissolved C concentration was greater than in the bulk sample and correspondingly the amount of ..cap alpha.. phase there was greater. The hardness of the subscales were related to the hardness of the aged, but uncarburized, material. For example, a material aged to 610 KHN produced a subscale of 1180 KHN, while one aged to 480 KHN produced a subscale of 660 KHN. The subscale had a uniform hardness across its width and grew parabolically with time. The activation energy for growth was 148 kJ/mole, a value near that for C diffusion in Ta. Carburizing experiments at elevated temperatures, above the ..beta../..cap alpha.. solvus, were completed and two limiting cases of subscale formation were identified. In one limit the amount of compound is constant across the subscale and in the other limit it varies linearly with composition across the subscale. 10 figures.

Experiments for the evaluation of a cold cathode electron gun are described. Different anode and cathode materials and configurations were tried. Small signal gains of 6.3 percent/cm were measured. It was found that the same small signal gains could be obtained with less energy deposition in the laser gas with the larger pre-ionizing currents from a cold cathode. Long-duration pulses were observed that were limited only by the electrical energy available in the Marx bank. (auth)
