Book excerpt: In the reactor technical assistance program, it has been shown that the fuel content of the ETR control rods can be increased by 75% to give a generated power increase (in a control rod) of 50% and a typical increase in excess reactivity of 0.55%, without exceeding heat transfer limitations. A metal fabrication facility was completed for developing and fabricating sample fuel plates for local research programs. Hydraulic tests on experimental thin-plate narrowchannel fuel elements showed flow distribution improved over that of conventional MTR fuel elements. In the search for stronger alloys to make possible elements having thinner plates, comparative strength tests were made on plates of 6061 and 1100 aluminum alloys (in the fully-annealed condition); results are reported. Oxidation rates for an aluminum-uranium sample exposed to water vapor have been shown to follow a linear rate law within close limits. A method has been developed for use of the RMF to determine effective cross sections in terms of neutron density, cadmium ratio, and characteristic neutron temperature. This method makes it possible to determine for a sample. by a reactivity measurement, parameters which can be used to express effective cross sections for the sample in other reactor spectra, provided their neutron temperature and 1/v cadmium ratio are known.

Available in PDF, EPUB and Kindle. Book excerpt: In reactor technical assistance, a linearization technique was developed which yields a good prediction of charge life for MTR after a core has operated for some 60 Mwd. A detailed comparison of relative statistical weights proportional to the square of neutron flux and experimental statistical weights, showed the two in good agreement, both for MTR and for ETR. An MTR startup accident calculation (void formation neglected) indicated that doubling the withdrawal rate for shim rods increases the calculated energy release in the power transient by only 3%. In an investigation of service life of MTR shim rods, examination of a Be-Cd rod that had logged 20,000 Mwd revealed that the Cd had changed to flakes; a fuel-Cd rod with 2545 Mwd of service showed no corrosion damage. RMF measurements of the buildup of U/sup 233/ in MTR-irradiated Th slugs, made as part of a continuing program, were analyzed and results are presented. A gamma-insensitive control system for RMF-type reactors has been proposed, based on a loop ihrough which a liquid circulates from the reactor core to an external detector where its neutron activation is measured. A stability study showed flow control requirements to be reasonable. Additional total cross sections were measured with the crystal spectrometer and fast chopper including those for Pu/sup 240/ U/sup 235/, U/sup 233/ Au, V, C, and B (in the thermal region) and for Pa/sup 231/, Np/sup 237/, and Ir (in the energy region

Available in PDF, EPUB and Kindle. Book excerpt: The effect of fast-neutron (>1 Mev) irradiation on the mechanical properties of structural metals and alloys was studied. Although the yield strengths and ultimate tensile strengths are increased su stantially for most materials, the ductility suffers severe decreases. This report presents these changes in properties of several structural metals for a number of neutron exposures within the 1.0 x 10 to the 18th power to 5.0 x 10 to the 21st power n/sq cm range. Data summarizing these effects on several classes of materials such as carbon steels, low-alloy steels, stainless steels, Zr-base alloys, ni-base alloys, Al-base alloys, and Ta are given. Additional data which show the influence f irradiation temperatures and of post-irradiation annealing on the radiation-induced property changes are also given and discussed. Increases as great as 175% in yield strength, 100% in ultimate strength, and decreases of 80% in total elongation are reported for fast-neutron exposures as great as 5 10 to the 21st power n/sq cm.
