In a cell containing several bipolar electrodes placed in series between two terminal electrodes, a flow of hydrogen is established from the terminal anode compartment toward the terminal cathode. An electrolyte feed containing tritium is continuously added to the system and is subsequently transported countercurrent to the hydrogen mass transfer. A cascaded system is established, in which effluent streams enriched and depleted in tritium can be withdrawn. The voltage drop is smaller at any bipolar electrode as compared to the voltage for normal electrolysis. Cell design is compact because isotope separation occurs at bipolar electrodes without evolution of gas. Isotope separation was demonstrated in laboratory cells where a steady-state tritium concentration gradient was attained. This gradient was in agreement with concentrations calculated from a derived mathematical model.

Book excerpt: Use of bipolar electrolysis with countercurrent electrolyte flow to separate hydrogen isotopes was investigated for the removal of tritium from light water effluents or from heavy water moderator. Deuterium-tritium and protium-tritium separation factors occurring on a Pd-25% Ag bipolar electrode were measured to be 2.05 to 2.16 and 11.6 to 12.4 respectively, at current densities between 0.21 and 0.50 A cm−2, and at 35 to 90°C. Current densities up to 0.3 A cm−2 have been achieved in continuous operation, at 80 to 90°C, without significant gas formation on the bipolar electrodes. From the measured overvoltage at the bipolar electrodes and the electrolyte conductivity the power consumption per stage was calculated to be 3.0 kwh/kg H2O at 0.2 A cm−2 and 5.0 kwh/kg H2O at 0.5 A cm−2 current density, compared to 6.4 and 8.0 kwh/kg H2O for normal electrolysis. A mathematical model derived for hydrogen isotope separation by bipolar electrolysis, i.e., for a square cascade, accurately describes the results for protium-tritium separation in two laboratory scale, multistage experiments with countercurrent electrolyte flow; the measured tiritum concentration gradient through the cascade agreed with the calculated values.

Book Synopsis Tritium Isotope Separation by : Gheorghe Vasaru
Download or read book Tritium Isotope Separation written by Gheorghe Vasaru and published by CRC Press. This book was released on 1993-03-25 with total page 330 pages. Available in PDF, EPUB and Kindle. Book excerpt: Tritium Isotope Separation is the first book to present a current overview of the separation processes for tritium isotopes. The book consists of two parts. Part I explores the sources of tritium and the evolution of the world's tritium inventory. Part II describes the processes and plants used for tritium isotope separation, enrichment methods for tritium for analytical purposes, methods for recovering and enriching tritium from nuclear and thermonuclear plants, and the laser method. The book in general emphasizes applications, performance, characterization, laboratory experiments, pilot plants and industrial production, reliability, and cost. An author index, subject index, list of acronyms and abbreviations, and glossary have been included to make the book an even more valuable reference. Tritium Isotope Separation will be an essential book for all nuclear energy engineers, nuclear physicists, and others working with various aspects of isotope separation science.

Download or read book Tritium Removal from Contaminated Water Via Infrared Laser Multiple-photon Dissociation written by and published by . This book was released on 1983 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Isotope separation by means of infrared-laser multiple-photon dissociation offers an efficient way to recover tritium from contaminated light or heavy water found in fission and fusion reactors. For tritium recovery from heavy water, chemical exchange of tritium into deuterated chloroform is followed by selective laser dissociation of tritiated chloroform and removal of the tritiated photoproduct, TCl. The single-step separation factor is at least 2700 and is probably greater than 5000. Here we present a description of the tritium recovery process, along with recent accomplishments in photochemical studies and engineering analysis of a recovery system.

Book excerpt: Methods for laser-assisted isotope separation of tritium, using infrared multiple photon dissociation of tritium-bearing products in the gas phase. One such process involves the steps of (1) catalytic exchange of a deuterium-bearing molecule XYD with tritiated water DTO from sources such as a heavy water fission reactor, to produce the tritium-bearing working molecules XYT and (2) photoselective dissociation of XYT to form a tritium-rich product. By an analogous procedure, tritium is separated from tritium-bearing materials that contain predominately hydrogen such as a light water coolant from fission or fusion reactors.
