Insights into the Reduction Mechanisms of Np(VI) to Np(V) by Carbohydrazide.

Journal of Physical Chemistry A, 2023
An efficient approach to Np separation in the Plutonium Uranium Reduction EXtraction (PUREX) process is to adjust Np(VI) to Np(V) by free-salt reductants, such as hydrazine and its derivatives.

Joint Evaluation of Neutron and Gamma-ray Multiplicity Analysis for Warhead Attributes

INMM ESARDA Joint Annual Meeting - Vienna, , Austria - May - 2023, 2023
We will present the concept of an attribute measurement system that uses the time-correlated detection of neutron-capture gamma rays together with neutrons to confirm the presence of several warhead attributes concurrently: (1) plutonium mass, (2 ...

Evaluation of the Hage-Cifarelli Three Parameter Model Under $\mathrm{K}_{\text {eff }}$ Variations

2025 IEEE Nuclear Science Symposium (NSS), Medical Imaging Conference (MIC) and Room Temperature Semiconductor Detector Conference (RTSD)
Accurate characterization of special nuclear material (SNM) is essential for a range of applications involving neutron detection. Neutron multiplicity counting (NMC) is a widely used nondestructive assay (NDA) technique that leverages time-correlated ...

TRIPOLI-4® calculations of neutron multiplicity counting rates of 3He array detectors and verification tests of an automatic MCNP-to-TRIPOLI conversion tool for recent ICSBEP subcritical experiments

EPJ Web of Conferences
TRIPOLI-4® is a general-purpose Monte Carlo radiation transport code developed at CEA Paris-Saclay center. It uses continuousenergy nuclear data to simulate neutron transport for diverse nuclear engineering fields.

Understanding the role of turbulence and biofilm on low density microplastic dynamics: An experimental approach towards natural conditions.

Journal of Hazardous Materials
The fate of microplastics (MP) in rivers is controlled by particle properties, biological interactions, and hydrodynamics, yet mechanisms governing near-bed behavior of low-density MP remain unclear.

Assessing the Accumulation of Microplastics in Earthworms (Eisenia fetida) Using Traditional Bioaccumulation Modeling and Synchrotron-Based Microcomputed Tomography.

Environmental Toxicology and Chemistry
Microplastics (MPs) are recognized as a ubiquitous contaminant in terrestrial ecosystems. Earthworms, which play key roles in soil structure, nutrient cycling, and ecosystem function, are important bioindicators for assessing MP exposure and fate ...
