• W1515741175 abstract "A study is underway to evaluate the technical performance and economic attractiveness of linear induction-driven Heavy Ion Fusion (HIF) as an energy source for electrical power generation. This study is a cooperative effort of several national laboratories, universities, industrial contractors and the Electric Power Research Institute (EPRI) under the leadership of Los Alamos National Laboratory. McDonnell Douglas Astronautics Company, assisted by Titan Systems, Inc, has the responsibility to integrate the cost and performance models of the driver, reactor and balance of plant systems, evaluate different system options and assess the overall technical and economic performance of an HIF power plant. Individual system options have been designed and analyzed by the other participants in the DOE-sponsored parent study and are provided for system integration and evaluation.This paper describes the integration and evaluation effort for the HIF Systems Assessment. Specific areas discussed include:• Definition of Systems Requirements• Development of Assessment Methodology• Characterization of System Options• Description of Systems Assessment Code• Assessment of Code Results• Ranking of System Options• Selection of Attractive System Options• Determination of Preferred Operating Parameter SpaceThe initial study effort was to define the system requirements from the standpoint of the overall power plant. This was accomplished by establishing overall power plant performance goals and specifications. The plant was assumed to be dedicated only to electrical power production in the 2020 time frame enabling the study to look beyond developmental and startup difficulties. The net plant output was defined to be between 400 and 1500 MWe which would allow investigating the effect of plant size.The methodology to assess the options is to model the performance and cost of all the major plant systems and incorporate these models into a system performance and economic computer model. The system options are parametrically modeled to enable investigation over large regions of parameter space. The major systems to be modeled include drivers, targets, beam transport, cavities and balance of plant. The driver examined in the study is the linear induction accelerator. The major discrete options include single-shell and double-shell targets with two-sided and symmetric illumination and reactor cavities protected by ceramic granules, liquid lithium jets, liquid lithium films, liquid lithium in flexible tubes, and magnetic fields. The balance of plant and facilities are defined to accommodate these systems. In addition to the discrete design options mentioned above, the cost sensitivity of the plant is investigated in relation to the major continuous parameters of repetition rate, beam energy, ion voltage, ion species and net plant output power.The assessment of the code results and ranking of the systems options is based largely upon the chosen figure-of-merit, the cost of electricity. This figure-of-merit considers the capital cost of the plant, the operating and maintenance costs, the fuel costs, the gross power output of the reactor, the thermal-to-electrical conversion efficiency and the recirculating power fraction. Total direct capital cost is also considered as a separate and distinct figure-of-merit. From the code results and the system option rankings, attractive HIF system option sets are identified along with preferred operating parameter spaces for each set. This information will provide guidance for future research and development activities on the more promising system options. The results also identify areas where innovation may enhance the competitiveness of HIF." @default.
