Materials Physics and Application (MPA) initiated a pilot project using a Radio Frequency Identification (RFID) Scanner and RFID barcodes for tracking and performing annual chemical inventories.
Radiation detection systems are a central pillar of NNSA’s nuclear security, nonproliferation, and stockpile stewardship mission. Radiation transport simulations are a prevalent tool in radiation detection R&D.
We will cover: Regulations, SDS requirements, Hazard determination, Precautionary statements/pictograms (labels), and other considerations.
This presentation discusses the objective of the project which is to provide a utility (among other utilities) that improves MCNP analysis post-processing and visualization capabilities. Much recent work has been done to improve MCNP post-processing and visualization. It also discusses the goals of the project, which are to create a product that is portable, open, easily interrogated by a user, no dependencies, including a mesh tally-to-VTK conversion, an EEOUT-to-VTK conversion, and an interactive, 3-D, visualization environments (e.g., ParaView). The presentation also discusses the reasons regarding why this is being done, which are to provide physical insight into behaviors and trends, to facilitate error mitigation (easier to “see” errors than “read” them), and to improve communication with collaborators. It also discusses why this is being done now as analyses are getting ever-more complicated and are more flexible in terms of build, test, and deployment capabilities.
Los Alamos National Laboratory (LANL) is the location of the Los Alamos Neutron Science Center (LANSCE). The presentation outlines the various components and capabilities at LANSCE.
Topics covered include: Types of problems which DRACO (Multiphysics simulation) was designed to address; Tools from nonequilibrium statistical mechanics; Rare events (Extreme value statistics); Transients (Diverging time scales); and, Thresholds (Absorbing phase transitions).
LANL purchased a man instrument (pulse dilation PMT) from the Sydor Instruments, Inc. The company requests to get experimental data obtained using the instrument, for their record.
This presentation will be used as part of training on the LANL owned (but open-sourced) Pavilion software.
A general overview of the DRACO computational chemistry model including model geometry, input decks, and validation.
Supporting information for LDRD report of thermochemical and thermophysical properties for the system of Ce metal and Ce hydride (deuteride). Knowledge of these properties is necessary in order to properly build a physics based model of the Ce ejecta evolution (conversion) in high pressure hydrogen gas.
The project involves the installation and activation of 42 roof-top or ground mount solar photovoltaic systems. The system will use a combination of roof-top photovoltaic panels and ground-mounted panels that will be installed on 40 tribal homes and 2 tribal buildings throughout the three participating reservations. The scope of work includes site preparation, equipment installation, system testing, and inspection by a third-party inspector, system activation, troubleshooting, and final activation. It also includes any electrical system upgrades, which are anticipated to accommodate the new PV system. The system will displace at least 50% of the combined total of electricity needed by the participating structures. Implementing these systems will also provide hands-on solar installation training to at least 20 Tribal community volunteers and job trainees.
This presentation covers site hydrogeologic setting (including geologic setting and faults and fractures), groundwater monitoring for RLWTF, monitoring well locations, monitoring suite and frequency, quality of wells, and defense in depth – groundwater monitoring coupled with use of engineering controls and visual inspections. The objectives of groundwater monitoring are early detection of any future noncompliant releases, providing additional safety net to support extensive administrative and engineering controls, and monitoring to characterize extent of groundwater effected by noncompliant discharge.
The purpose of this work is to determine MTD effectiveness and cost for protecting non-IP C2 networks, experiment on networks used in satellite systems, and randomize features (e.g. device address) to prevent adversary from conducting reconnaissance.
