Book excerpt: E.I. duPont de Nemours and Company is commissioned by the US Department of Energy to operate the Savannah River Plant and Laboratory. The primary purpose of the plant is to produce radioactive materials for national defense. In keeping with current technology, new processes for the production of tritium are being developed. Three main objectives of this new technology are to ease the processing of, ease the storage of, and to reduce the operating costs of the tritium production facility. Research has indicated that the use of metal hydrides offers a viable solution towards satisfying these objectives. The Hydrogen and Fuels Technology Division has the responsibility to conduct research in support of the tritium production process. Metal hydride technology and its use in the storage and transportation of hydrogen will be reviewed.

Book excerpt: The use of La-Ni-Al metal hydrides to process and store tritium presents unique problems to the handling of tritium. All hydrogen isotopes are ''trapped'' in La-Ni-Al alloys as a function of homogeneity and the degree of activation, or number of full cycles the material experiences before being exposed to tritium. To a lesser extent, the mole fraction of aluminum has an effect on the number of cycles needed for full activation. Data is presented which shows the effect of La-rich second phases on the retentium of protium, the x-ray diffraction line broadening as a function of number of cycles, and the observed ''heel'' in the alpha region of the isotherm due to Ni-Al second phases. There also appears to be an increase in solubility of tritium due to the lattice expansion on the metal.

Download or read book Tritium and Helium-3 in Metals written by Rainer Lässer and published by Springer Science & Business Media. This book was released on 2013-03-13 with total page 167 pages. Available in PDF, EPUB and Kindle. Book excerpt: Hydrogen can behave as an alkaline metal or a halogen and can react with nearly all elements of the periodic table. This explains the large number of metal hydrides. Since T. Graham's first observation of the absorption of hydrogen in palladium in 1866 the behaviour of hydrogen in metals has been studied very extensively. The interest was motivated by the possible application of metal-hydrogen systems in new technologies (e.g., moderator material in nuclear fission reactors, reversible storage material for thermal energy and large amounts of hydrogen) and by the fact that metal hydrides show very exciting physical properties (e.g., superconductivity, quantum diffusion, order-disorder transitions, phase diagrams, etc.). Many of these properties have been determined for the stable hydrogen isotopes Hand D in various metals. In comparison, very little is known about the behaviour of the ra dioactive isotope tritium in metals. This book is a first attempt to summarize part of the knowledge of tritium gained in the last few years. In addition to the task of presenting the properties of tritium in metals, I have tried to compare these data with those of protium and deuterium. Furthermore, helium-3 is connected inse parably with tritium via the tritium decay. Therefore one chapter of this book is solely devoted to the curious properties of helium in metals caused mainly by its negligible solubility.

This book was released on 1977 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Hydriding studies of zirconium on an engineering scale was continued for application to tritium storage systems. Two runs were made with zirconium sponge in the 297 to 319°C temperature range at a hydrogen flow rate of 2.72 cm3 at STP/g Zr-min. No significant difference in reaction rate was observed between 99.95 and 99.999 percent minimum purity hydrogen. Seven runs were made with 0.065-in.-thick zirconium sheet at a temperature range of 415 to 526°C. Some inconsistency was found in the zirconium sheet reaction data, which is probably the result of differences in buildup of diffusion barrier from specimen to specimen. The reaction with zirconium sheet was found to be more dependent on the degree of outgassing and hydrogen purity, compared with sponge. Maximum reaction rates were 0.080 and 1.34 cm3 of H2 at STP/cm2-min. for 99.95 and 99.999 percent minimum purity hydrogen, respectively.

This book was released on 1976 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Laboratory work was continued on hydriding of zirconium sponge and rod under varying conditions of temperature (400 to 900°C) and pressure (0-1000 torr) to determine optimum conditions for the formation of hydrides with desirable mechanical properties. Titanium sponge and rod were also hydrided for comparison. Zirconium and titanium samples containing tritium were prepared and initial leach data were obtained. Leach rates for zirconium in distilled water ranged from 1.1 x 10−6 to 4.8 x 10−6 cm/day under static conditions and from 2.1 x 10−6 to 1.1 x 10−5 cm/day under dynamic conditions. The leach rates for titanium sponge and rod under static conditions ranged from 2.2 x 10−7 to 1.7 x 10−6 cm/day. Construction of the engineering scale equipment has been completed and testing has been started prior to operation. Lysimeter testing of polymer impregnated tritiated concrete (PITC) specimens has continued. After sixty-two weeks, the average of the four test specimens indicates a a linear rate of release with a slope of 5.23 x 10−2 cm/yr. beginning after 250 days. A duplicate PITC static leach specimen in distilled water after 386 days indicates a linear rate of release with a slope of 3.18 x 10−2 cm/yr. Developmental work is continuing on the injector technique for PITC. Nontritiated prototype specimens, as well as tritiated specimens for static leach testing in distilled water, were prepared.

The construction of engineering-scale equipment for the tritium storage in metal hydride process has been started. Various concrete and polymer reinforcement materials, as well as a polyester additive to the styrene monomer, were investigated in an attempt to improve the physical properties of polymer-impregnated tritiated concrete.
Download or read book In-bed Measurement of Tritium Loading in Process Metal Hydride Beds written by and published by . This book was released on 1988 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The Replacement Tritium Facility at Savannah River Plant will make extensive use of metal hydride technology for the storage, pumping, isotopic separation, and compression of hydrogen isotopes. Two options were considered for routine accountability of tritium stored in metal hydride beds. One option was to use standard P-V-T-mass spectrometry techniques after desorption of storage beds to tanks of known volume. The second option was to develop a technique for direct measurement of bed loading. It was thought that such a technique would be more rapid and would account for heel, although some accuracy would be lost. The static nitrogen and flowing nitrogen methods were considered for this option. The flowing nitrogen method was eventually selected because it was insensitive to bed physical properties and isotopic gas composition, as well as being more accurate and easier to automate.

Download or read book A PROTOTYPE FOUR INCH SHORT HYDRIDE (FISH) BED AS A REPLACEMENT TRITIUM STORAGE BED. written by and published by . This book was released on 2011 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The Savannah River Site (SRS) tritium facilities have used 1st generation (Gen1) metal hydride storage bed assemblies with process vessels (PVs) fabricated from 3 inch nominal pipe size (NPS) pipe to hold up to 12.6 kg of LaNi{sub 4.25}Al{sub 0.75} metal hydride for tritium gas absorption, storage, and desorption for over 15 years. The 2nd generation (Gen2) of the bed design used the same NPS for the PV, but the added internal components produced a bed nominally 1.2 m long, and presented a significant challenge for heater cartridge replacement in a footprint limited glove-box. A prototype 3rd generation (Gen3) metal hydride storage bed has been designed and fabricated as a replacement candidate for the Gen2 storage bed. The prototype Gen3 bed uses a PV pipe diameter of 4 inch NPS so the bed length can be reduced below 0.7 m to facilitate heater cartridge replacement. For the Gen3 prototype bed, modeling results show increased absorption rates when using hydrides with lower absorption pressures. To improve absorption performance compared to the Gen2 beds, a LaNi{sub 4.15}Al{sub 0.85} material was procured and processed to obtain the desired pressure-composition-temperature (PCT) properties. Other bed design improvements are also presented.

Download or read book Tritium Measurement Technique Using In-bed'' Calorimetry written by and published by . This book was released on 1991 with total page 7 pages. Available in PDF, EPUB and Kindle. Book excerpt: One of the new technologies that has been introduced to the Savannah River Site (SRS) is the production scale use of metal hydride technology to store, pump, and compress hydrogen isotopes. For tritium stored in metal hydride storage beds, a unique relationship does not exist between the amount of tritium in the bed and the pressure-volume-temperature properties of the hydride material. Determining the amount of tritium in a hydride bed after desorbing the contents of the bed to a tank and performing pressure, volume, temperature, and composition (PVTC) measurements is not practical due to long desorption/absorption times and the inability to remove tritium heels'' from the metal hydride materials under normal processing conditions. To eliminate the need to remove tritium from hydride storage beds for measurement purposes, and in-bed'' tritium calorimetric measurement technique has been developed. The steady-state temperature rise of a gas stream flowing through a jacketed metal hydride storage bed is measured and correlated with power input to electric heaters used to simulate the radiolytic power generated by the decay of tritium to 3He. Temperature rise results for prototype metal hydride storage beds and the effects of using different gases in the bed are shown. Linear regression results shows that for 95% confidence intervals, temperature rise measurements can be obtained in 14 hours and have an accuracy of {plus minus}1.6% of a tritium filled hydride storage bed.
