One of the goals of DOE’s MPACT program is to develop nuclear material accounting (NMA) methods for next generation, advanced fuel cycles such as Molten Salt Reactors (MSR). There are several challenges for NMA of MSR, for example, the high temperature and high dose rates, at which the measurements need to be performed. The goal of the proposed research is to develop high-count-rate, high temper ...

The trafficking of special-nuclear material (SNM) and radiological sources remains a serious threat to the security of the United States. To counter nuclear trafficking, the Department of Homeland Security (DHS) relies on Radiation Portal Monitor’s (RPMs) that scan vehicles and cargo containers across U.S. points of entry for radiation signatures. The current RPMs predominantly consist of polyvi ...

Low-cost, high-density Gamma ray plastic scintillators with fast decay and high light yield superior to inorganic scintillators and semiconductor detectors are highly needed in the fields of nuclear physics, national security, border control, along with various medical and industrial sectors. Chemelectronics LLC will team up with the University of California, Los Angeles to development and commerc ...

Portable X-ray sources are widely used by security, nuclear safeguard, and defense agencies. However, currently employed sources have significant drawbacks, limiting their practical applications. For example, radioisotope-based gamma sources have many associated safety and security issues. Betatrons have very low-dose emission due to low duty cycle, and non-ideal SWaP characteristics, making them ...

A major concern with nuclear energy is the safe storage of the spent nuclear fuel before final disposal. A monitoring sensor located inside a storage canister to provide direct measurements of internal conditions is of particular interest to DOE. Conventional wireless sensors have inherent limitations because the stainless steel canister shields the RF signals from wireless sensors inside the cani ...

Sealed radioisotope sources containing radioactive materials have been used for decades in oil and gas well logging tools, primarily to determine the density, porosity, and hydrogen content, and, in some instances, elemental compositions, of the various rock types and their contained fluids. Two types of sealed radioactive sources are the most used: gamma-ray used by the formation density log and ...

To enable fast and robust bias modulators for gyrotrons used in the nuclear fusion systems, GaNify LLC will develop a power switch capable of switching 50-kV and 1-A within 1 µs, without the need of series-stacking. This new technology will significantly reduce the circuit complexity and shorten the modulation voltage rise time. The new 50-kV power switch is based upon the demonstrated 10-kV gall ...

This project supports the ARPA-E Mission Area of “improving management, clean-up and disposal of radioactive waste and spent nuclear fuel”. A series of tests and demonstrations for deep borehole disposal canisters at the Deep Borehole Demonstration Center in Cameron, Texas - coupled with development of a US supply chain and global tech-to-market partnerships - will mature the canister to Techn ...
