The Nuclear Medicine National HQ System database is a series of MS Excel spreadsheets and Access Database Tables by fiscal year. They consist of information from all Veterans Affairs Medical Centers (VAMCs) performing or contracting nuclear medicine services in Veterans Affairs medical facilities. The medical centers are required to complete questionnaires annually (RCS 10-0010-Nuclear Medicine Service Annual Report). The information is then manually entered into the Access Tables, which includes: * Distribution and cost of in-house VA - Contract Physician Services, whether contracted services are made via sharing agreement (with another VA medical facility or other government medical providers) or with private providers. * Workload data for the performance and/or purchase of PET/CT studies. * Organizational structure of services. * Updated changes in key imaging service personnel (chiefs, chief technicians, radiation safety officers). * Workload data on the number and type of studies (scans) performed, including Medicare Relative Value Units (RVUs), also referred to as Weighted Work Units (WWUs). WWUs are a workload measure calculated as the product of a study's Current Procedural Terminology (CPT) code, which consists of total work costs (the cost of physician medical expertise and time), and total practice costs (the costs of running a practice, such as equipment, supplies, salaries, utilities etc). Medicare combines WWUs together with one other parameter to derive RVUs, a workload measure widely used in the health care industry. WWUs allow Nuclear Medicine to account for the complexity of each study in assessing workload, that some studies are more time consuming and require higher levels of expertise. This gives a more accurate picture of workload; productivity etc than using just 'total studies' would yield. * A detailed Full-Time Equivalent Employee (FTEE) grid, and staffing distributions of FTEEs across nuclear medicine services. * Information on Radiation Safety Committees and Radiation Safety Officers (RSOs). Beginning in 2011 this will include data collection on part-time and non VA (contract) RSOs; other affiliations they may have and if so to whom they report (supervision) at their VA medical center.Collection of data on nuclear medicine services' progress in meeting the special needs of our female veterans. Revolving documentation of all major VA-owned gamma cameras (by type) and computer systems, their specifications and ages. * Revolving data collection for PET/CT cameras owned or leased by VA; and the numbers and types of PET/CT studies performed on VA patients whether produced on-site, via mobile PET/CT contract or from non-VA providers in the community. Types of educational training/certification programs available at VA sites * Ongoing funded research projects by Nuclear Medicine (NM) staff, identified by source of funding and research purpose. * Data on physician-specific quality indicators at each nuclear medicine service. Academic achievements by NM staff, including published books/chapters, journals and abstracts. * Information from polling field sites re: relevant issues and programs Headquarters needs to address. * Results of a Congressionally mandated contracted quality assessment exercise, also known as a Proficiency study. Study results are analyzed for comparison within VA facilities (for example by mission or size), and against participating private sector health care groups. * Information collected on current issues in nuclear medicine as they arise. Radiation Safety Committee structures and membership, Radiation Safety Officer information and information on how nuclear medicine services provided for female Veterans are examples of current issues.The database is now stored completely within MS Access Database Tables with output still presented in the form of Excel graphs and tables.

Background work on establishing Technology cost ranges for Nuclear study.The study is a technical analysis of the potential risks and uncertainties of South Africa’s proposed commitment to 9.6 GW of nuclear power. The objective of the study is to review this commitment in comparison to a more flexible planning approach that aims to minimise costs. It includes three main tiers of analysis: the first builds two alternative futures, so that we can understand the implications of different investment strategies in uncertain future worlds; the second models the socioeconomic impacts of the commitment to nuclear power versus a flexible planning approach in each of these futures (i.e. committed nuclear versus least-cost investment plans in different futures); the third estimates the risks of an increase in the electricity price to the South African economy and consumers.

Between 1954 and 1996, more than 200 nuclear power projects were publicly announced in the USA. Barely half of these projects were completed and generated power commercially. Existing research has highlighted a number of potential explanations for the varying siting outcomes of these projects, including contentious political protest, socioeconomic, and political conditions within potential host communities, regulatory changes (‘ratcheting’), and cost overruns. However, questions remain about which of these factors, if any, had an impact on these outcomes. We created a new data set of 228 host communities where siting was attempted to illuminate the factors that led projects towards either completion or cancellation. We include county-level regulatory, reactor-specific, demographic, and political factors which may correlate with the outcomes of attempts to site nuclear reactors over this time period. The full draft of our forthcoming peer reviewed article in International Journal of Energy Research can be found at http://papers.ssrn.com/sol3/papers.cfm?abstract_id=2423935. We include the Stata dataset, the codebook, and the .do file used to create the statistical analysis for the paper.

Abstract Prognostics solutions for mission critical systems require a comprehensive methodology for proactively detecting and isolating failures, recommending and guiding condition-based maintenance actions, and estimating in real time the remaining useful life of critical components and associated subsystems. A major challenge has been to extend the benefits of prognostics to include computer servers and other electronic components. The key enabler for prognostics capabilities is monitoring time series signals relating to the health of executing components and subsystems. Time series signals are processed in real time using pattern recognition for proactive anomaly detection and for remaining useful life estimation. Examples will be presented of the use of pattern recognition techniques for early detection of a number of mechanisms that are known to cause failures in electronic systems, including: environmental issues; software aging; degraded or failed sensors; degradation of hardware components; degradation of mechanical, electronic, and optical interconnects. Prognostics pattern classification is helping to substantially increase component reliability margins and system availability goals while reducing costly sources of "no trouble found" events that have become a significant warranty-cost issue. Bios Aleksey Urmanov is a research scientist at Sun Microsystems. He earned his doctoral degree in Nuclear Engineering at the University of Tennessee in 2002. Dr. Urmanov's research activities are centered around his interest in pattern recognition, statistical learning theory and ill-posed problems in engineering. His most recent activities at Sun focus on developing health monitoring and prognostics methods for EP-enabled computer servers. He is a founder and an Editor of the Journal of Pattern Recognition Research. Anton Bougaev holds a M.S. and a Ph.D. degrees in Nuclear Engineering from Purdue University. Before joining Sun Microsystems Inc. in 2007, he was a lecturer in Nuclear Engineering Department and a member of Applied Intelligent Systems Laboratory (AISL), of Purdue University, West Lafayette, USA. Dr. Bougaev is a founder and the Editor-in-Chief of the Journal of Pattern Recognition Research. His current focus is in reliability physics with emphasis on complex system analysis and the physics of failures which are based on the data driven pattern recognition techniques.

TIMES models for Nuclear Study.A linked model approach is used in this study firstly, in order to capture the complexities of the energy sector as well as the impacts of different build plans on the economy. Secondly this approach is employed to capture the feedback of price and investment effects on energy demand. The South African Times Model (SATIM), a technology rich energy model and e-SAGE (the energy extension to South Africa’s general equilibrium model) are partially linked through the electricity sector and driven by similar assumptions. The e-SAGE model is a dynamic recursive computable general equilibrium (CGE) model developed by UNU-WIDER. The main input is the 2007 South African Social Accounting Matrix (SAM). The SAM is a set of accounts that represents all of the productive sectors and commodities in South Africa, as well as factor markets, enterprises, households, and the ‘rest of the world.’ The South African TIMES Model (SATIM) is an inter-temporal bottom-up optimisation energy model of South Africa built around the Markal-TIMES platform. SATIM uses linear or mixed integer programming to solve the least-cost planning problem of meeting projected future energy demand, given assumptions such as the retirement schedule of existing infrastructure, future fuel costs, future technology costs, learning rates, and efficiency improvements, as well as any given constraints such as the availability of resources. Read the Technology report for a full description of the modelling methodology.

Residual heat removal pump (RRA pump) is a core equipment used to remove radioactive decay heat from the core and maintain thermal balance in the primary loop during nuclear reactor shutdown. Its sealing and structural integrity directly affect the safe and stable operation of nuclear power plants. Therefore, it is necessary to evaluate the leakage rate of mechanical seals of RRA pumps under thermal shock. By establishing a three-dimensional model of the RRA pump and its mechanical seal in a nuclear power plant, the unidirectional thermal fluid solid coupling method was used to calculate and analyze the internal flow field and temperature field of the RRA pump and mechanical seal under specific operating conditions. The axial deformation of the mechanical seal was obtained, and the leakage characteristics of its main sealing area were analyzed. The analysis results show that due to the frictional heat generated by the dynamic and static ring end faces of the mechanical seal and the flushing of cooling water, the temperature of the sealing end face first increases and then decreases in the radial direction, resulting in a narrow middle and wide ends of the leakage channel of the sealing end face. The calculated mechanical seal leakage rate is basically consistent with the actual operating conditions of a nuclear power plant. The research results provide an accurate numerical simulation method for evaluating the sealing performance of RRA pumps in the reactor primary loop, which has practical engineering significance.

The new Presidential directive to place humans on Mars and establish bases on the moon will require advances in nuclear thermal propulsion and power generation. Nuclear thermal propulsion has a combined advantage in power density, ISP and low fuel/mass ratio over other propulsion means for these missions. To meet the needs of reactor safety, health monitoring and performance, light-weight, real-time, in-core neutron and gamma monitoring sensors need to be developed. Luna is proposing to develop a real-time miniature gamma and neutron dosimeter. This hybrid sensor will measure gamma and neutron dose independently, as well as temperature, along a single optical fiber at the same location. The transducer will be less than 5mm long and 1mg in mass. This dosimeter will enable real-time determination of reactor power level, health and remaining fuel as well as shielding effectiveness. The design will be based on EFPI measurement techniques developed by Luna and demonstrated in high-radiation and temperature environments. During the Phase I, Luna will demonstrate feasibility of the proposed dosimeter in a nuclear reactor. Phase II will optimize the sensors and demodulation system for performance and cost, considering space hardening constraints, and demonstrate the system in high radiation and high temperature environments.
