Seventy-Five Years of Nuclear Criticality Safety Documents - A Bibliography
A collection of nuclear criticality documents was begun in the 1970s at the University of California’s Lawrence Livermore Laboratory (now Lawrence Livermore National Laboratory). Documents in this bibliography are dated as early as 1940. The early documents described experimental work that was of vital importance to the safe use of fissile materials at nuclear reactors, the facilities for preparing or transporting nuclear fuel, or its eventual storage. The experiments were of direct value to support safe operations with fissile material, but they were also needed for validating early physics data and calculational methods and then for validating computational methods used in criticality safety evaluations. Bibliographic information from the past seventy-five years have been entered into a computerized bibliographic database. The database continues to expand. Publications were issued several decades ago based on the information collected at that time. Our new publication is based on a current “snapshot” of the present status of the database. Contributions of information or corrections to this bibliography will be appreciated.
Patching EAF-2010 into CINDER2008 Cross Section Libraries
CINDER2008 [1] comes with multi-group cross section libraries using most recent evaluated cross section data. The multi-group cross sections are weighted with three spectra: fission, fusion and flat. However, due to data format incompatibilities with the CINDER2008library maker tool, many of the reaction cross sections adapted from EAF-2010 [2] are either truncated or completely missing. Therefore it is essential to regenerate the CINDER2008 libraries with compatible EAF-2010 data. The updated cross section libraries are compared to those of the current cross section libraries in the sections below following a brief introduction of the CINDER2008 cross section libraries and a description of the method of generating cross sections for the CINDER2008 code. In the remainder of this document, we will refer to the libraries distributed with CINDER2008before October 2016 as the "current" libraries, and those described in this work as the "updated" libraries. In figures, the current library data may be shown with the library namewith or without “cur” appended, while the updated library data may be shown with "mod" appended.
Five rad things you can do with an “atom smasher”
Early in the 20th century, scientists began to unravel the atom’s inner workings, discovering tiny particles like protons, neutrons and electrons. To better understand how these particles work, pioneer scientists developed and built “atom smashers,” huge machines that accelerate particles to near the speed of light and crash them into each other at extremely high energies.

Reevaluation of Three Cold War-Era Buildings at Technical Area 22
The U.S. Department of Energy, National Nuclear Security Administration, Los Alamos Field Office (Field Office) reevaluated three magazines (buildings 7, 8, and 10) at Technical Area (TA) 22, Los Alamos National Laboratory (LANL or the Laboratory) (Map 1). This reevaluation was conducted because the magazines have been identified as candidates for preservation due to their association with the almost 40 years of Cold War-era detonator research conducted at adjacent building TA-22-1 (Maps 2–4), a property that is eligible for inclusion in the Manhattan Project National Historical Park (MAPR) for its role in the assembly of the wartime Fat Man bomb. Cold War-era magazines, TA-22-7, -8, and -10, were originally determined not eligible for listing in the National Register of Historic Places (Register) in DX Division’s Facility Strategic Plan: Consolidation and Revitalization at Technical Areas 6, 8, 9, 14, 15, 22, 36, 39, 40, 60, and 69 (McGehee et al. 2005) in consultation with the State Historic Preservation Officer on April 18, 2006. Many of the magazines at TA-22 are of identical construction, and at the time of the initial evaluation, other magazines were selected as the best examples of type for the purpose of architectural documentation. The reevaluation is being conducted because the status of TA-22-1 and its immediate area have changed since the MAPR was authorized in December 2014. The three magazines, along with a magazine that was previously determined eligible in 2006 (TA-22- 9), are within one of the proposed boundaries for the MAPR at LANL and are also now considered candidates for preservation. These magazines were constructed in 1949 to support detonator research, development, and testing, and have served as reinforced storage facilities for high explosives since their construction.
In Situ Indexing and Query Processing of AMR Data
We have developed the first, holistic, Adaptive Mesh Refinement (AMR) capable, in situ query framework to ensure the tractability of the current- and next-generation AMR simulation analysis on the path to extreme scale. We have addressed key issues pertaining to in situ analysis, memory hierarchy, generalized parallel indexing, index-compression, and real-time access pattern detection. We have published the following research papers in high profile peer reviewed computer science conferences: (a) Parallel In Situ Detection of Connected Components in Adaptive Mesh Refinement Data; (b) AMR-aware In Situ Indexing and Scalable Querying; (c) Pattern-driven dynamic data layout optimization; (d) In situ Storage Layout Optimization for AMR Spatio-temporal Read Accesses; (e) AMRZone: A Runtime AMR Data Sharing Framework for Scientific Applications; (f) Exploring Memory Hierarchy and Network Topology for Runtime AMR Data Sharing Across Scientific Applications.
Abstract for CRADA between VariGrid Explorations Inc. and NETL (AGMT-0863)
As the energy industry continues to invest in data, big data, and advanced analytics to improve production, reduce operation and maintenance costs, improve safety, and reduce risks, uncertainty will serve as a limiting factor in the success of these operations. Intuitive communication of uncertainty can provide more transparency in the decision-making process; offering the ability to more accurately evaluate the risk and impact of decisions, identify data and knowledge gaps, and evaluate trade-offs. The issue of uncertainty will thus play a large role in the success of investments that rely on big data and data analytics. However, no robust method for representation of uncertainty in spatial data visuals currently exists. As such, uncertainty is, at best, communicated using multiple independent visuals and aggregated in final displays, or frequently omitted altogether. Failure to accurately and effectively quantify and communicate uncertainty poses a barrier, limiting critical information that would better allow businesses to make more accurate and intelligent decisions.
2018 Annual Report Laboratory Directed Research and Development at Pacific Northwest National Laboratory
A national laboratory must establish and maintain an environment in which creativity and innovation are encouraged and supported in order to fulfill its missions and remain viable in the long term. As such, multiprogram laboratories are given discretion to allocate a percentage of their operating budgets to support research and development projects that align to PNNL’s and DOE’s missions and support the missions of other federal agencies, including DHS, DOD, and others. Individual project reports comprise the bulk of this LDRD report. The Laboratory focuses its LDRD research on scientific assets that often address more than one scientific discipline.
Open Chemistry Collaborative in Diversity Equity (OXIDE)
This award from the Division of Chemistry (CHE) of the National Science Foundation, with additional support from the National Institutes of Health (National Institute of general Medical Sciences) and the Department of Energy (Basic Energy Sciences) supports Prof. Rigoberto Hernandez of the Georgia Institute of Technology and his colleagues in their efforts through the Open Chemistry Collaborative in Diversity Equity (OXIDE) at increasing participation in the chemical sciences by all members of American society, including members of groups that have been traditionally underrepresented in the sciences. They will do this through a broad series of activities including workshops, assessments of interventions performed within chemistry departments, and broad dissemination of e.g. best practices. Work like that of Prof. Hernandez and his colleagues is aimed at finding effective means for recruitment and retention of the most talented Americans into the chemical enterprise. Success in these efforts will have profound implications for American economic prosperity and continued competitiveness.
The Bird project: Using Big Data tools to support Search Analytics
The Bird project explored the use of big data analytics tool to improve the findability of information within the Sandia internal network. We were able to perform query classification utilizing the supervised learning algorithms in the Apache Spark library. By relying on the distributed processing capabilities provided by the Apache Hadoop framework, we successfully processed the large query log files needed to train the models in this effort. The capabilities developed in this project are being used to enhance the effectiveness of the enterprise search engine.
