Thermal stress tests on Type 1, SM-1A Core II fuel ele-ment sections were performed to study plate distortion and determine its dependency on temperature distribution, temperature differential, initial flatness, and ripple length. Test results will be correlated with the analytical model and used to predict ripple growth in other plate-type fuel elements. The tests showed that ripple growth is dependent on initial flatness of the plate and that the characteristic shape of ripples is maintained at all temperature differentials: The tests also showed that the ripple growth rate for a ripple of 5 mil initial magnitude is approximately 0.12 mils/ deg F for a peak temperature differential of 103 deg F and that the apparent relationship between ripple net growth and length is 1.3 mil/in. of ripple for a peak temperature differential of 103 deg F. A permanent distortion of 2 mils for a complete temperature cycle from 0 to 103 to O deg F differential was found. The temperature profile across the plate width was found to affect the magnitude of ripple growth. (auth)

Current NPR fuel production plans call for a thick layer (0.030 inch or greater) of 5% Be + 95% Zry-2 braze alloy in the closure region. This requirement was imposed to eliminate many of the production welding problems brought about by the presence of the low melting braze alloy between two surfaces of Zircaloy. All GEH-4 irradiations in the past have involved very thin braze lines (0.015 inch or less). As a part of the fuel evaluation program it is essential to run a comparative irradiation to determine what effect the braze line thickness has on the stability of the fuel closure. For this purpose three fuel elements were prepared, two with a braze thickness of 0.030 inch and one with a braze thickness of 0.015 inch. To provide a more severe thermal stress, the I&E geometry was used. Five MTR cycles should be sufficient to test this fuel concept. This report details this test proposal.

The conduct of outage work in the discharge areas of the Hanford production reactors has always been complicated by personnel exposure to radiation from the contaminants which accumulate in the effluent water piping in the course of normal operations. These containments represent trace impurities in the cooling water, together with corrosion products, which are irradiated in passing through the reactor and then deposit in the unshielded rear face piping. Radioactive residues also accumulate on the external surfaces of this same complex and congested hardware. The radiation from these depositions increased as power levels and effluent water temperatures were raised, and by 1956 it was apparent that corrective steps would be essential to effective future maintenance work in the discharge areas. It is the purpose of this report to summarize the subsequent development and application of the chemical process for rear face piping decontamination which is being used so effectively in connection with the tube replacement program and other major outrage work.

An evaluation was undertaken to compare the results of various thicknesses of flat tensile specimens with results of round specimens from the same uranium plate, and to analyze the effect of some of the fabrication and testing variables on the test results. Flat specimens gave good reproducibility, particularly at thicknesses of 0.150 and 0.200 inch, but showed biases when compared to round specimens which varied as a function of thickness. Fabrication variables such as omitting hand polishing produced small increases in the bias and a substantial increase in the scatter of the results. Specimen alignment was found to have a substantial influence on the shape of the curve obtained.

This document describes the advantages and limitations of Hanford production facilities. In addition to summarizing the technical parameters of the reactors and separations plants and their mechanical features, the unique aspects of these facilities to the production of special materials in which the Commission may be interested have been discussed. As the primary difference between the B-C-D-DR-F-H reactors and the K reactors and the K reactors is in the number and length of process channels. This report is addressed primarily to the 2000-tube reactors. K reactor characteristics are within the range of lattice and flexibility parameters described.

An analog recording technique was investigated in which pulses from a scintillation counter are stretched to a width compatible with the bandwidth of the recorder. Three types of playback systems were considered, i.e., unequalized velocity, equalized velocity, and flux sensitive playback. The results of the three systems were found to be comparable. Loss in resolution in the process was primarily due to nonuniformities in magnetic tape properties and maintenance of an adequate head to tape contact. Instrumental line widths of the order of 3% were achieved using equipment of moderate cost. (For preceding period see ARF- 1151-5.) (auth)

"Dust and gas masks and respirators have been an effective method under certain environmental conditions to reduce the inhalation of toxic aerosols. Under many conditions, however, their efficacy has been seriously questioned. It is the purpose of this study to evaluation over-all respirator performance on fine aerosols and to develop equipment whereby a greater degree of respiratory protection may be assured with reliability for highly toxic atmospheres."
