Los Alamos National Laboratory Modular Pumped Hydro Feasibility Study for Santa Fe Community College

This presentation on Economic Energy Assessment given at Santa Fe Community College, New Mexico explains the rational for energy storage and the process used to assess the need for energy storage and how to develop a teaching tool to be used in the community. Further, Modular Pumped Hydro (MPH) energy is explained and rationale is presented supporting the need for renewable energy.

High-Precision Plutonium Isotopic Compositions Measured on Los Alamos National Laboratory’s General’s Tanks Samples: Bearing on Model Ages, Reactor Modelling, and Sources of Material. Further Discussion of Chronometry

In this study, we re-analyzed late-1940’s, Manhattan Project era Plutonium-rich sludge samples recovered from the ''General’s Tanks'' located within the nation’s oldest Plutonium processing facility, Technical Area 21. These samples were initially characterized by lower accuracy, and lower precision mass spectrometric techniques. We report here information that was previously not discernable: the two tanks contain isotopically distinct Pu not only for the major (i.e., 240 Pu, 239 Pu) but trace ( 238 Pu , 241 Pu, 242 Pu) isotopes. Revised isotopics slightly changed the calculated 241 Am- 241 Pu model ages and interpretations.

Next Generation Safeguards Initiative Efforts at Los Alamos National Laboratory: Developing Our Human Capital FY2015

This report documents the accomplishments of the Safeguards HCD Fiscal Year 2015 (FY15) Project Work Plan, highlighting LANL’s work as well as the accomplishments of our NGSI-sponsored students, graduate and postdoctoral fellows, and mid-career professionals during this past year. While fiscal year 2015 has been a year of transition in the Human Capital Development area for LANL, we are working to revitalize our efforts to promote and develop Human Capital in Safeguards and Non-proliferation and are looking forward to implementing new initiatives in the coming fiscal year and continuing to transition the knowledge of staff who have been on assignment at IAEA and Headquarters to improve our support to HCD.

2015 Final Reports from the Los Alamos National Laboratory Computational Physics Student Summer Workshop

The two primary purposes of LANL’s Computational Physics Student Summer Workshop are (1) To educate graduate and exceptional undergraduate students in the challenges and applications of computational physics of interest to LANL, and (2) Entice their interest toward those challenges. Computational physics is emerging as a discipline in its own right, combining expertise in mathematics, physics, and computer science. The mathematical aspects focus on numerical methods for solving equations on the computer as well as developing test problems with analytical solutions. The physics aspects are very broad, ranging from low-temperature material modeling to extremely high temperature plasma physics, radiation transport and neutron transport. The computer science issues are concerned with matching numerical algorithms to emerging architectures and maintaining the quality of extremely large codes built to perform multi-physics calculations. Although graduate programs associated with computational physics are emerging, it is apparent that the pool of U.S. citizens in this multi-disciplinary field is relatively small and is typically not focused on the aspects that are of primary interest to LANL. Furthermore, more structured foundations for LANL interaction with universities in computational physics is needed; historically interactions rely heavily on individuals’ personalities and personal contacts. Thus a tertiary purpose of the Summer Workshop is to build an educational network of LANL researchers, university professors, and emerging students to advance the field and LANL’s involvement in it. This report includes both the background for the program and the reports from the students.

MEMORANDUM OF UNDERSTANDING between Los Alamos National Laboratory (LANL) and Savannah River National Laboratory (SRNL) for Analytical Chemistry Support for Oxide Production Samples

This MOU establishes the responsibilities and requirements for the packaging and transport of plutonium dioxide (PuO 2 ) samples for shipment from LANL to SRNL. The scope includes the shipping, packaging, quality assurance (QA), inspection, and documentation requirements to successfully obtain the chemical and isotopic characteristics of the PuO 2 . The requirements in this document are necessary, but not sufficient to execute this work and do not imply exemption from contractual requirements at either site. This document is not intended to specify all of the processes and procedures necessary to execute this work. This MOU also establishes appropriate requirements, goals, and expectations. Each party will establish a technical point of contact (POC) who will be responsible for addressing issues as they arise
