Strategies to Control Costs at U.S. Commercial Nuclear Power Plants
Commercial nuclear power plants in the United States are not cost competitive because of high operating and maintenance costs and historically low natural gas prices, resulting in the potential for premature plant closure of up to 25% of the operating power plants by 2025. Premature plant closure could impact the consumer through higher electricity rates, increased air pollution, and electric grid instability from increased renewable usage. Grounded in the behavioral decision theory, the purpose of this qualitative single case study was to explore successful strategies nuclear leaders used to control costs and ensure competitiveness. Data were collected through semistructured interviews with eight nuclear leaders in the Eastern United States, organizational business plans, change management plans, and innovation process documents. Data were analyzed using thematic analysis. Four themes emerged: management engagement is required to sustain long-term change that controls cost, leaders emphasize the use of technology that drives cost-effective solutions, leaders seek organizational cost initiatives that provide greater efficiencies and opportunities, and leaders must engage and empower the workforce to achieve business excellence. A key recommendation is for nuclear leaders to place the same level of emphasis on cost control strategies as they place on nuclear safety. The implications for positive social change include the potential for sustaining a viable noncarbon emitting energy source that mitigates the carbon impacts to climate change and does not emit air pollutants during operation
Cyber Supply Chain Risk Management: Implications for the SOF Future Operating Environment
The emerging Cyber Supply Chain Risk Management (C-SCRM) concept assists at all levels of the supply chain in managing and mitigating risks, and the authors define C-SCRM as the process of identifying, assessing, and mitigating the risks associated with the distributed and interconnected nature of information and operational technology products and service supply chains. As Special Operations Forces increasingly rely on sophisticated hardware and software products, this quick, well-researched monograph provides a detailed accounting of C-SCRM associated laws, regulations, instructions, tools, and strategies meant to mitigate vulnerabilities and risks—and how we might best manage the evolving and ever-changing array of those vulnerabilities and risks

Identifying environmental safety and health requirements for the Fernald Environmental Restoration Management Corporation
This presentation will describe the Fernald Environmental Restoration Management Corporation`s (FERMCO) Standards/Requirements Identification Documents (S/RlDs) Program, the unique process used to implement it, and the status of the program. We will also discuss the lessons learned as the program was implemented. The Department of Energy (DOE) established the Fernald site to produce uranium metals for the nation`s defense programs in 1953. In 1989, DOE suspended production and, in 1991, the mission of the site was formally changed to one of environmental cleanup and restoration. The site was renamed the Fernald Environmental Management Project (FEMP). FERMCO`s mission is to provide safe, early, and least-cost final clean-up of the site in compliance with all regulations and commitments. DOE has managed nuclear facilities primarily through its oversight of Management and Operating contractors. Comprehensive nuclear industry standards were absent when most DOE sites were first established, Management and Operating contractors had to apply existing non-nuclear industry standards and, in many cases, formulate new technical standards. Because it was satisfied with the operation of its facilities, DOE did not incorporate modern practices and standards as they became available. In March 1990, the Defense Nuclear Facilities Safety Board issued Recommendation 90-2, which called for DOE to identify relevant standards and requirements, conduct adequacy assessments of requirements in protecting environmental, public, and worker health and safety, and determine the extent to which the requirements are being implemented. The Environmental Restoration and Waste Management Office of DOE embraced the recommendation for facilities under its control. Strict accountability requirements made it essential that FERMCO and DOE clearly identify applicable requirements necessary, determine the requirements` adequacy, and assess FERMCO`s level of compliance
A Comprehensive Profile of Decoding and Comprehension in Autism Spectrum Disorders
The present study examined intake data from 384 participants with autism spectrum disorders (ASD) and a comparison group of 100 participants with dyslexia on nine standardized measures of decoding and comprehension. Although diagnostic groups were based on parental reports and could not be verified independently, we were able to observe significant distinctions between subject groups. Overall findings confirm previous results of a disassociation between decoding and comprehension in ASD. Using a larger sample than previous studies and a greater variety of measures, a pattern of relatively intact decoding skills paired with low comprehension was found in autism, PDD-NOS, and Asperger’s. In contrast, the dyslexic group showed the opposite pattern of stronger comprehension and weaker decoding
Mars Spark Source Prototype
The Mars Spark Source Prototype (MSSP) hardware has been developed as part of a proof of concept system for the detection of trace metals such as lead, cadmium, and arsenic in Martian dusts and soils. A spark discharge produces plasma from a soil sample and detectors measure the optical emission from metals in the plasma that will allow their identification and quantification. Trace metal measurements are vital for the assessment of the potential toxicity of the Martian environment for human exploration. The current method of X-ray fluorescence can yield concentrations only of major species. Other instruments are incompatible with the volume, weight, and power constraints for a Mars mission. The instrument will be developed primarily for use in the Martian environment, but would be adaptable for terrestrial use in environmental monitoring. This paper describes the Mars Spark Source Prototype hardware, the results of the characterization tests, and future plans for hardware development
