Contingency Contractor Optimization Phase 3 Sustainment Platform Requirements - Contingency Contractor Optimization Tool - Prototype

Durfee, Justin D.; Frazier, Christopher R.; Bandlow, Alisa; Gearhart, Jared L.; Jones, Katherine

Sandia National Laboratories (Sandia) is in Phase 3 Sustainment of development of a prototype tool, currently referred to as the Contingency Contractor Optimization Tool - Prototype (CCOTP), under the direction of OSD Program Support. CCOT-P is intended to help provide senior Department of Defense (DoD) leaders with comprehensive insight into the global availability, readiness and capabilities of the Total Force Mix. The CCOT-P will allow senior decision makers to quickly and accurately assess the impacts, risks and mitigating strategies for proposed changes to force/capabilities assignments, apportionments and allocations options, focusing specifically on contingency contractor planning. During Phase 2 of the program, conducted during fiscal year 2012, Sandia developed an electronic storyboard prototype of the Contingency Contractor Optimization Tool that can be used for communication with senior decision makers and other Operational Contract Support (OCS) stakeholders. Phase 3 used feedback from demonstrations of the electronic storyboard prototype to develop an engineering prototype for planners to evaluate. Sandia worked with the DoD and Joint Chiefs of Staff strategic planning community to get feedback and input to ensure that the engineering prototype was developed to closely align with future planning needs. The intended deployment environment was also a key consideration as this prototype was developed. Initial release of the engineering prototype was done on servers at Sandia in the middle of Phase 3. In 2013, the tool was installed on a production pilot server managed by the OUSD(AT&L) eBusiness Center. The purpose of this document is to specify the CCOT-P engineering prototype platform requirements as of May 2016. Sandia developed the CCOT-P engineering prototype using common technologies to minimize the likelihood of deployment issues. CCOT-P engineering prototype was architected and designed to be as independent as possible of the major deployment components such as the server hardware, the server operating system, the database, and the web server. This document describes the platform requirements, the architecture, and the implementation details of the CCOT-P engineering prototype.

Energy Storage System Guide for Compliance with Safety Codes and Standards

Conover, David R.; Cole, Pam C.

Codes, standards and regulations (CSR) governing the design, construction, installation, commissioning and operation of the built environment are intended to protect the public health, safety and welfare. While these documents change over time to address new technology and new safety challenges there is generally some lag time between the introduction of a technology into the market and the time it is specifically covered in model codes and standards developed in the voluntary sector. After their development, there is also a timeframe of at least a year or two until they are adopted. Until existing model codes and standards are updated or new ones developed and then adopted, one seeking to deploy energy storage technologies or needing to verify an installation’s safety may be challenged in applying current CSRs to an energy storage system (ESS).

Conducting a Nuclear Security Assessment

Leach, Janice; Snell, Mark K.

There are three general steps that make up a nuclear security assessment: 1. Develop data Libraries that indicate how effective the physical protection measures are both individually but also as parts of subsystems and actual systems. 2. Perform Path Analysis 3. Perform Scenario Analysis. Depending upon the nature and objectives of the assessment not all three of these steps may need to be performed; for example, at facilities with simple layouts there may not be a need to perform path analysis. Each of these steps is described within this report.

An investigation of DTOcean foundation and anchor systems

Gomez, Steven P.; Jensen, Richard P.; Heath, Jason E.

This memo documents the mechanical loading analysis performed to date for the DTOcean program WP4 foundation and anchor systems submodule. FEA simulations were performed to validate design requirements defined by Python based analytic simulations of the WP4 program Naval Facilities Engineering Command (NAVFAC) tool. This FEA procedure focuses on worst case loading scenarios on direct mbedment anchor and suction caisson designs produced by WP4. These models include a steel casing and steel anchor with soft clay and dense sand surrounding the steel components respectively.

Phosphorous dimerization in GaP high-pressure polymorph

Sandia journal manuscript; Not yet accepted for publication

Lavina, Barbara; Kim, Eunja; Cynn, Hyunchae; Weck, Philippe F.; Seaborg, Kelly; Siska, Emily; Meng, Yue; Evans, Williams

We report on the experimental and theoretical characterization of a novel GaP polymorph formed by laser heating of a single crystal of GaP-II in its stable region near 43 GPa. Thereby formed unstrained multigrain sample at 43 GPa and 1300 K, allowed high-resolution crystallographic analysis. We find an oS24 as an energetically optimized crystal structure contrary to oS8 reported by Nelmes et al. (1997). Our DFT calculation confirms a stable existence of oS24 between 18 – 50 GPa. The emergence of the oS24 structure is related to the differentiation of phosphorous atoms between those forming P-P dimers and those forming P-Ga bonds only. Bonding anisotropy explains the symmetry lowering with respect to what is generally expected for semiconductors high-pressure polymorphs. The metallization of GaP does not occur through a uniform change of the nature of its bonds but through the formation of an anisotropic phase containing different bond types.

Best Paper Award: Gathering Threat Intelligence Through Computer Network Deception

Arrowsmith, Marie D.

Presented at the 2016 IEEE International Symposium on Technologies for Homeland Security (HST), this LDRD-funded research received a Best Paper award, the highest award presented at the conference. The research focused on developing, implementing, and testing a novel computer network operations architecture that enables proactive defense by managing and monitoring enterprise resource allocations and network flows. The architecture leverages three emerging concepts: software-defined networks, cloud computing, and deception, to enable the detection and identification of anomalous access and intrusions to adjust to the dynamic nature of the adversary and to provide a mechanism to discover and react to the adversary’s attacks in a methodical and proactive manner. Additionally, the work allows network defenders to gather information on an adversary’s tools, tactics and procedures, providing insight into the “what, why, and how” of the adversary’s operations. A summary of the work presented at IEEE can be found at http://tiny.sandia.gov/8d8lu.

Plasma Cleaning Research for Z

Tang, Ricky; Miller, Paul A.; Barnat, Edward

Z is a high-current pulsed-power generator located at Sandia National Laboratories. It is capable of delivering 100-ns, 30-MA current pulses to loads used for materials studies, weapons-effects simulation, and nuclear-fusion research. Under some conditions, a significant fraction of the current does not reach the load but is shunted across the inter-electrode vacuum gap that leads to the load. That undesirable current loss is thought to be due to excessive plasma generation and flow from the electrodes into the vacuum gap. Much past work suggests that this current loss may be reduced if contaminants on or near the surfaces of the electrodes are removed by plasma discharge cleaning. This report describes light-lab work performed in the past year to evaluate and understand plasma cleaning, and to develop the technology required for future tests on Z.

Walker, Matthew; Kruizenga, Alan M.; Weck, Philippe F.; Withey, Elizabeth A.; Fleming, Darryn; Rochau, Gary E.

The supercritical carbon dioxide (S-CO2) Brayton Cycle has gained significant attention in the last decade as an advanced power cycle capable of achieving high efficiency power conversion. Sandia National Laboratories, with support from the U.S. Department of Energy Office of Nuclear Energy (US DOE-NE), has been conducting research and development in order to deliver a technology that is ready for commercialization. There are a wide range of materials related challenges that must be overcome for the success of this technology. At Sandia, recent work has focused on the following main areas: (1) Investigating the potential for system cost re duction through the introduction of low cost alloys in low temperature loop sections, (2) Identifying material options for 10MW RCBC systems, (3) Understanding and resolving turbine degradation, (4) Identifying gas foil bearing behavior in CO2, and (5) Identifying the influence of gas chemistry on alloy corrosion. Progress in each of these areas is provided in this report.

Origin and Tunability of Unusually Large Surface Capacitance in Doped Cerium Oxide Studied by Ambient-Pressure X-Ray Photoelectron Spectroscopy

Advanced Materials

Gopal, Chirranjeevi B.; El Gabaly, Farid; Mcdaniel, Anthony H.; Chueh, William C.

The surface chemical capacitance of ceria and SDC was investigated using in situ ambient pressure X-ray photoelectron spectroscopy (APXPS) in H2 H 2O environments at elevated temperatures. The spectra were collected in situ after equilibrating the samples under oxygen chemical potentials spanning -2.95 and -3.44 eV versus 1 atm O2. Consequently, the volumetric chemical capacitance of the surface, in the range of 103-104Fcm-3, is nearly two orders of magnitude larger than that of the bulk. Addition of Sm leads to a slight decrease of surface Ce3+ concentration, but a 10-fold enhancement in the surface capacitance under H2 H 2O atmospheres. Our hypothesis for this observation is that Sm lowers defect interactions. The areal surface capacitance calculated for SDC is in good agreement with literature values extrapolated from electrochemical measurements.
