C56-18d-273148The portfolio of future energy solutions must consider increased hydrogen use, as it serves the critical need of being a carbon-free energy transport medium. However, hydrogen is highly flammable and is a potent indirect greenhouse gas. Hydrogen facilities that will enable socially- responsible use of this energy source therefore need to detect, quantify, and mitigate hydrogen emissi ...

We propose simulating and constructing a prototype and demonstration brassboard of a Secondary Emission Sensor Module (SESM) for ionizing radiation, as a proof of principle and guide to Phase II and beyond. The simulation and design studies will guide module construction and point to future uses. The module is anticipated to have ~30 stages of sheet dynode with an areal size ~15x15 cm. It will be ...

C56-20a-273160Machine driven processes such as pumps, fans, compressed air, and materials handling and processing accounted for 68% of electricity use (2,840 TBtu direct use) by U.S. manufacturing in 2010 (DoE 2014). Many of the involved electric motors use existing silicon diode-based switches for power conversion. Replacing these Si- or even the more recent SiC-based switches could unlock a pote ...

Lawrence Livermore National Laboratory’s (LLNL) National Ignition Facility (NIF) recently announced the achievement of fusion ignition for the first time, by delivering 2.05 MJ of energy to the target, resulting in 3.15 MJ of fusion energy output. Further power scaling of the system will require addressing a number of power-limiting technical issues. One such limitation is the anti-reflection co ...

C56-40h-273244 Nuclear power plants have historically relied on analog systems for control and operations; however, due to the aging nature of these systems and the fact that many of their components are no longer manufactured, nuclear power plant operators are increasingly replacing these legacy control systems with modern digital operational technology systems. This greater degree of connectivit ...

The technical net power generation potential for the United States from marine energy is 2,300 TWh/year with ~95% coming from regions outside the Gulf of Mexico, the only current large scale supply chain for offshore needs. An additional 4,100 TWh/year of ocean thermal energy comes from Pacific territories. 53% of the United States' technical energy resource comes from wave energy; California, Ore ...

C56-40e-273310 Nuclear microreactors producing < 20 MW of power are being researched for portable and on-site energy production in situations such as disaster relief, mobile encampments, or remote locations where access to the regional power grid is limited or difficult. In order to facilitate this mass production of nuclear reactors, radiation shielding must be produced which is reliable, replace ...

1. Problem StatementCurrent industrial-scale rare earth element separation technologies are based on solvent extraction schemes which produce large amounts of undesirable chemical waste, including the loss of volatile organic solvents and reagents employed in the treatment of feed streams. These concerns have severely limited the development of U.S.-based rare earth element separation facilities. ...

Polymer electrolyte membrane fuel cells (PEMFCs) are promising for heavy duty vehicles, however increasing the operating cell voltage to improve energy conversion and fuel efficiency can lead to electrochemical corrosion of metallic bipolar plates (BPP). Several corrosion mechanisms can occur simultaneously releasing metal ions that poison the membrane impacting the overall performance of the PEMF ...

As we make progress in the design and fabrication of ITER experimental fusion reactor there is new focus on the next generation commercial fusion reactors. Several design concepts have been put forward including the DEMOnstration power station followed by the PROTOtype power station and other concepts for compact reactors. Electron Cyclotron Resonance Heating (ECRH) and Electron Cyclotron Current ...
