LANL Accident Analysis and Atmospheric Dispersion Modeling [Slides]

After completion of this course, the analyst will understand the differences between an unmitigated analysis and a mitigated analysis. After completion of this course, the analyst will know the key receptors that a radiological and hazardous chemical accident analysis must consider. After completion of this course, the analyst will understand how to calculate a radiological release source term and a toxic chemical release source term for various phenomenology. After completion of this course, the analyst will understand how to calculate a radiological and toxic chemical health insult to key receptors and compare to consequence thresholds. After completion of this course, the analyst will understand the role of atmospheric dispersion in radiological and toxic consequence calculations. After completion of this course, the analyst will understand atmospheric dispersion modeling and the inputs to and outputs from the MACCS/POSTMAX codes.

Rediscovered photographs of J. Robert Oppenheimer’s 1964 visit to LANL

National Security Research Center staff recently rediscovered a trove of images of J. Robert Oppenheimer’s last known visit to the Laboratory, tucked away among the NSRC’s collections of millions of classified and unclassified photographs and not seen for over thirty years. Oppenheimer, who served as our first Director from 1943–1945, led the United States’ successful wartime effort to develop the world’s first atomic weapons in just 27 months. He left the Lab shortly after World War II ended, but came back in May of 1964 to deliver a lecture about Niels Bohr at the Civic Auditorium (now Duane Smith Auditorium) and visit the Los Alamos Scientific Laboratory Museum (which would become the Bradbury Science Museum), as is captured in these photos.

ISO 14001:2015 Environmental Management System Management Assessment Internal Review Assessing Organization: EPC-ES LANL-ASMT-2022-0289 (Spring 2023)

The Environmental Protection and Compliance Division-Environmental Stewardship Group of Los Alamos National Laboratory conducted a management assessment that supports the implementation of the Los Alamos National Laboratory Environmental Management System according to International Organization for Standardization (ISO) 14001:2015, Environmental Management System. The assessment resulted in zero findings of nonconformity, five opportunities for improvement, four noteworthy practices, and three observations.

LANL HPC Data Center Monitoring: Summer 2023 Talk [Slides]

Data Center Monitoring is the understanding of everything that happens in the Data Center. Our Ultimate (and probably unreachable) Goal is a holistic view of the Data Center and an understanding of how everything is correlated. We get to that Understanding by collecting logs and metrics, analyzing data, displaying information for customers, and staying alert on events.

Forensics, Instruments, Turtles & Hot Sauce: The Role of an Isotope Geochemist at LANL [Slides]

Measurable quantities of U in Turtle and Tortoise scute. Turtle samples from areas of known history of radionuclide releases found to have non-natural U isotope signatures. These signatures match what we know about the release of uranium radionuclides at each site. Able to determine quantifiable changes in the U concentration and isotope composition along individual layers of growth (representing seven years of life). Possible correlations with historical releases of U from Oak Ridge site.
