Available in PDF, EPUB and Kindle. Book excerpt: The blanket is linked to the H2SO4 vaporization units and SO3 decomposition reactor with either sodium or helium. The engineering and safety problems associated with these choices are discussed. This H2SO4 step uses about 90% of the TMR heat and is best close-coupled to the nuclear island. The rest of the process we propose to be driven by steam and does not require close-coupling. The sodium loop coupling seems to be preferable at this time. We can operate with a blanket around 1200 K and the SO3 decomposer around 1050 K. This configuration offers double-barrier protection between Li-Na and the SO3 process gases. Heat pipes offer an attractive alternate to provide an additional barrier, added modularity for increased reliability, and tritium concentration and isolation operations with very little thermal penalty.

This book was released on 1981 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: This paper identifies the sulfuric acid step as the critical part of the thermochemical cycle in dictating the thermal demands and temperature requirements of the heat source. The General Atomic Sulfur-Iodine Cycle is coupled to a Tandem Mirror. The sulfuric acid decomposition process step is focused on specifically since this step can use the high efficiency electrical power of the direct converter together with the other thermal-produced electricity to Joule-heat a non-catalytic SO3 decomposer to approximately 1250°K. This approach uses concepts originally suggested by Dick Werner and Oscar Krikorian. The blanket temperature can be lowered to about 900°K, greatly alleviating materials problems, the level of technology required, safety problems, and costs. A moderate degree of heat has been integrated to keep the cycle efficiency around 48%, but the number of heat exchangers has been limited in order to keep hydrogen production costs within reasonable bounds.

This book was released on 1980 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Candidate materials are discussed and initial choices made for the critical elements in a liquid Li-Na Cauldron Tandem Mirror blanket and the General Atomic Sulfur-Iodine Cycle for thermochemical hydrogen production. V and Ti alloys provide low neutron activation, good radiation damage resistance, and good chemical compatibility for the Cauldron design. Aluminide coated In-800H and siliconized SiC are materials choices for heat exchanger components in the thermochemical cycle interface.
Book Synopsis Chemical Engineering Challenges in Driving Thermochemical Hydrogen Processes with the Tandem Mirror Reactor by :
Download or read book Chemical Engineering Challenges in Driving Thermochemical Hydrogen Processes with the Tandem Mirror Reactor written by and published by . This book was released on 1980 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The Tandem Mirror Reactor is described and compared with Tokamaks, both from a basic physics viewpoint and from the suitability of the respective reactor for synfuel production. Differences and similarities between the TMR as an electricity producer or a synfuel producer are also cited. The Thermochemical cycle chosen to link with the fusion energy source is the General Atomic Sulfur-Iodine Cycle, which is a purely thermal-driven process with no electrochemical steps. There are real chemical engineering challenges of getting this high quality heat into the large thermochemical plant in an efficient manner. We illustrate with some of our approaches to providing process heat via liquid sodium to drive a 1050 K, highly-endothermic, catalytic and fluidized-bed SO3 Decomposition Reactor. The technical, economic, and safety tradeoffs that arise are discussed.
Book Synopsis Producing Thermochemical Hydrogen with the Tandem-mirror Reactor by :
Download or read book Producing Thermochemical Hydrogen with the Tandem-mirror Reactor written by and published by . This book was released on 1982 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Fusion power holds the promise to supply not only electricity but also fuels to meet the balance of our energy needs. A new integrated power and breeding blanket design is described for tandem mirror reactors. The blanket incorporates features that make it suitable for synthetic fuel production. In particular, it is matched to the thermal and electrical power requirements of the General Atomic water-splitting process for production of hydrogen. Some improvements to the high temperature chemical process steps are described. These improvements are expected to allow production of hydrogen at about $13/GJ wholesale, including financing costs, capital amortization, and profit.

Book excerpt: A summary of the progress of the overall total development effort of the General Atomic (GA) sulfur-iodine thermochemical water-splitting cycle over the last two years is reported. The major accomplishments have been the following: (1) Significant improvements in the chemistry of the process. (2) Development, review, and revision of an engineering flowsheet, resulting in a thermal process efficiency of 47%. (3) Screening, identification, and testing of potential materials-of-construction for the corrosive process fluids. (4) Small-scale demonstration of the cycle in a closed loop under recycle conditions. (5) Installation of bench-scale equipment and demonstration of parts of the process in this system. (6) Development of a conceptual, preliminary flowsheet for the GA sulfur-iodine cycle driven by solar energy. The results of the work carried out during the last two years have demonstrated that thermochemical water splitting by the sulfur-iodine cycle is a feasible process and have provided confidence that thermal efficiencies in the range of 50% are achievable.

Book excerpt: An improved version of the tandem mirror fusion reactor is presented in which a power gain factor Q approx. 10 to 20 can be obtained at a few 100 MWe electrical output with much simpler technology in the end plugs. The improvement is obtained by raising the electron temperature in the end plugs well above that in the central cell (which would be ignited). The heating power required to maintain the high electron temperature is greatly reduced - to 20 to 40 MW per plug - by creating negative depressions in the potential that serve to thermally insulate electrons in the end plugs from those in the central cell. The overall concept and several proposed methods for creating the thermal barriers are discussed. A reactor example is then discussed.

This book was released on 2010 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The realization of the hydrogen as an energy carrier for future power sources relies on a practical method of producing hydrogen in large scale with no emission of green house gases. Hydrogen is an energy carrier which can be produced by a thermochemical water splitting process. The Sulfur-Iodine (SI) process is an example of a water splitting method using iodine and sulfur as recycling agents.
