There is a fundamental need for a high-performance computing (HPC) approach to computational electromagnetics (CEM) modeling tools suitable for designing and optimizing the next generation photonics devices- The dramatic grown of telecommunications bandwidth requirements is fueling demand for advanced manufacturing methods of next-generation devices capable of incorporating new phenomena such as p ...

The recent events at the Fukushima nuclear power plant highlight the need for enhanced accident tolerance. Of particular concern is the overheating of standard zirconium alloy cladding in a loss of coolant accident (LOCA). One of the leading candidates for future claddings is a silicon carbide (SiC) composite. However, it is clear that due to the inherent brittle nature of ceramics and the intrins ...

Neutron scattering is one of the most useful methods of studying the structure and dynamics of matter. These methods require large installations at national laboratories, such as Oak Ridge National Laboratory (ORNL), National Institute of Standards and Technology (NIST) and other facilities constructed or planned in the US and around the world. These facilities serve a large and diverse community ...

Accelerators are necessary for the fundamental study of matter and its origins. A critical component of accelerators are the niobium superconducting radio frequency (SRF) cavities, which are used to accelerate the particles. Because of the significant number of niobium SRF cavities required for each accelerator, innovative manufacturing techniques are needed to reduce fabrication costs and to ensu ...

To make a viable tokamak reactor concept, efficient, robust steady state current drive is required. RF power is among the leading contenders due to its high efficiency and penetration to the plasma core without density limits. To minimize impact on tritium breeding, high power density RF antennas are desired. At present, electrical breakdown limits the power density to ~10 MW/m2. Recent results at ...

Dry storage of spent nuclear fuel (SNF) is canisters can be threatened by corrosion of the metallic canisters which incur substantial repair and replacement costs and logistical issues. A novel cold spray repair and mitigation approach is proposed to repair corroded SNF canisters and mitigate the corrosion threat for fabricated canisters. The proposed work utilizes a novel cold spray technique whe ...

TECHNICAL ABSTRACT: CFDRC proposes the creation of an innovative location-based threat tracking and notification system to allow users to receive hazardous weather messages from the NWS with their call to action, allow users to receive custom-tailored messages about threats, and visualize relevant weather information within their area. The focus is on a tool that allows this information to be comm ...

In fusion plasmas, ion cyclotron range of frequency (ICRF) and lower hybrid range of frequency (LHRF) power is anticipated to be a primary auxiliary heating and current drive sources in next step tokamak experiments like ITER. From a technological perspective, several challenges remain including electrical breakdown and material compatibility with a nuclear environment. Copper has been the prima ...

The recent events at the Fukushima nuclear power plant highlight the need for enhanced accident tolerance. Of particular concern is the overheating of standard zirconium alloy cladding material in a loss of coolant accident (LOCA). One of the leading, high-risk/high-reward candidates for future claddings is a silicon carbide (SiC) composite material. However, the inherent open porosity present in ...

525 Solutions will manufacture highly economical and biodegradable uranium-from-seawater sorbents from fishing industry waste, and provide them to government-designated mining companies, at the same time leveraging the governmental funds to create a sustainable chitin products business, enabling economic growth and job creation in both the chitin products and fishing industries.
