UCLA Tokamak Program Close Out Report

The results of UCLA experimental fusion program are summarized. Starting with smaller devices like Microtor, Macrotor, CCT and ending the research on the large (5 m) Electric Tokamak. CCT was the most diagnosed device for H-mode like physics and the effects of rotation induced radial fields. ICRF heating was also studied but plasma heating of University Type Tokamaks did not produce useful results due to plasma edge disturbances of the antennae. The Electric Tokamak produced better confinement in the seconds range. However, it presented very good particle confinement due to an "electric particle pinch". This effect prevented us from reaching a quasi steady state. This particle accumulation effect was numerically explained by Shaing's enhanced neoclassical theory. The PI believes that ITER will have a good energy confinement time but deleteriously large particle confinement time and it will disrupt on particle pinching at nominal average densities. The US fusion research program did not study particle transport effects due to its undue focus on the physics of energy confinement time. Energy confinement time is not an issue for energy producing tokamaks. Controlling the ash flow will be very expensive.

Light Water Reactor Sustainability Program A Reference Plan for Control Room Modernization: Planning and Analysis Phase

The U.S. Department of Energy’s Light Water Reactor Sustainability (LWRS) program is collaborating with a U.S. nuclear utility to bring about a systematic fleet-wide control room modernization. To facilitate this upgrade, a new distributed control system (DCS) is being introduced into the control rooms of these plants. The DCS will upgrade the legacy plant process computer and emergency response facility information system. In addition, the DCS will replace an existing analog turbine control system with a display-based system. With technology upgrades comes the opportunity to improve the overall human-system interaction between the operators and the control room. To optimize operator performance, the LWRS Control Room Modernization research team followed a human-centered approach published by the U.S. Nuclear Regulatory Commission. NUREG-0711, Rev. 3, Human Factors Engineering Program Review Model (O’Hara et al., 2012), prescribes four phases for human factors engineering. This report provides examples of the first phase, Planning and Analysis. The three elements of Planning and Analysis in NUREG-0711 that are most crucial to initiating control room upgrades are: • Operating Experience Review: Identifies opportunities for improvement in the existing system and provides lessons learned from implemented systems. • Function Analysis and Allocation: Identifies which functions at the plant may be optimally handled by the DCS vs. the operators. • Task Analysis: Identifies how tasks might be optimized for the operators. Each of these elements is covered in a separate chapter. Examples are drawn from workshops with reactor operators that were conducted at the LWRS Human System Simulation Laboratory HSSL and at the respective plants. The findings in this report represent generalized accounts of more detailed proprietary reports produced for the utility for each plant. The goal of this LWRS report is to disseminate the technique and provide examples sufficient to serve as a template for other utilities’ projects for control room modernization.

Vehicle Technologies Program Government Performance and Results Act (GPRA) Report for Fiscal Year 2015

The U.S. Department of Energy’s Office of Energy Efficiency and Renewable Energy’s Vehicle Technologies Office (VTO) invests in research, development, demonstration, and deployment of advanced vehicle technologies under a diverse set of technology programs. This report provides estimates of the benefits that would accrue from successfully developing and deploying these technologies relative to a “Base case” that represents a future in which there is no VTO-supported vehicle technology development. This was done by estimating fuel use, primary energy use, and greenhouse gas (GHG) emissions from light-, medium- and heavy-duty vehicles, including energy and GHG emissions from fuel production for the Base case and the program “Target” case. The Target case represented the future with completely successful deployment of VTO technologies. Market penetrations of different vehicle types with and without VTO technologies were projected using market share models, and a stock and energy accounting model was used to make projections of energy consumption and GHG emissions for the Base and Target cases. The differences between the Base case and the Target case were attributed to VTO technologies. Improvements in fuel economy of various vehicle types and the resulting fuel savings by the on-road vehicle stock were attributed to individual VTO technology areas, which included batteries and electric drives, advanced combustion engines, fuels and lubricants, materials (i.e., reducing vehicle mass, also called “lightweighting”), and for medium- and heavy-duty vehicles, reduction in rolling and aerodynamic resistance.

Scoping Study Using Randomized Controlled Trials to Optimize Small Buildings' and Small Portfolios' (SBSP) Energy Efficiency Programs

This report is an initial step in determining whether randomized controlled trials (RCTs) should be used by the U.S. Department of Energy (DOE), utilities, and others to optimize energy efficiency programs targeting the small buildings and small portfolios (SBSPs) community. This scoping study reviews the use of RCTs to evaluate consumer purchasing and decision-making behaviors and to inform energy-efficient decision making. The scoping study discusses the relevant work, gaps in existing work, and potential value in pursuing further RCTs as related to energy-efficiency decision making in the SBSPs community. Our findings show that the factors that drive consumer behavior toward the purchasing of green products or energy efficiency programs remain complex, requiring further study of the underlying behavior mechanisms leading to environmental concern and action. Although small- and medium-sized businesses may share some purchasing behaviors with individual consumers and large commercial portfolios, important differences should be considered. Factors that are relevant to businesses include firm size to determine economies of scale, regulation, age, and turnover of capital equipment. Marketing approaches to promote green services such as energy efficiency need to go beyond a conventional cost-benefit analysis to include the highlighting of the psychological benefits and delivery of practical benefits, such as energy efficiency.

Light Water Reactor Sustainability Program: BWR High-Fluence Material Project: Assessment of the Role of High-Fluence on the Efficiency of HWC Mitigation on SCC Crack Growth Rates

As nuclear power plants age, the increasing neutron fluence experienced by stainless steels components affects the materials resistance to stress corrosion cracking and fracture toughness. The purpose of this report is to identify any new issues that are expected to rise as boiling water reactor power plants reach the end of their initial life and to propose a path forward to study such issues. It has been identified that the efficiency of hydrogen water chemistry mitigation technology may decrease as fluence increases for high-stress intensity factors. This report summarizes the data available to support this hypothesis and describes a program plan to determine the efficiency of hydrogen water chemistry as a function of the stress intensity factor applied and fluence. This program plan includes acquisition of irradiated materials, generation of material via irradiation in a test reactor, and description of the test plan. This plan offers three approaches, each with an estimated timetable and budget.

The FEMP Awards Program: Fostering Institutional Change and Energy Management Excellence

This report assesses the use of institutional change principles and the institutional impact of award-winning projects through interviews with 22 Department of Energy Federal Energy Management Program (DOE FEMP) award winners. Award winners identified institutional facilitators and barriers in their projects and programs as well as factors in their implementation processes, thus providing information that can guide other efforts. We found that award winners do use strategies based on eight principles of institutional change, most frequently in terms of making changes to infrastructure, engaging leadership, and capitalizing on multiple motivations for making an energy efficiency improvement. The principles drawn on the least often were commitment and social empowerment. Award winners also faced five major types of obstacles that were institutional in nature: lack of resources, constraints of rules, psychological barriers, lack of information, and communication problems. We also used the seven categories of Energy Management Excellence (EME) as a lens to interpret the interview data and assess whether these categories relate to established institutional change principles. We found that the eight principles reflect strategies that have been found to be useful in improving energy efficiency in organizations, whereas the EME categories capture more of a blend of social contextual factors and strategies. The EME categories fill in some of the social context gaps that facilitate institutional change and energy management excellence, for example, personal persistence, a culture that supports creativity and innovation, regular engagement with tenants, contractors, and staff at all levels. Taking together the use of principles, EME criteria, and obstacles faced by interviewees, we make recommendations for how FEMP can better foster institutional change in federal agencies.

Using Discrete Event Simulation for Programming Model Exploration at Extreme-Scale: Macroscale Components for the Structural Simulation Toolkit (SST).

Discrete event simulation provides a powerful mechanism for designing and testing new extreme- scale programming models for high-performance computing. Rather than debug, run, and wait for results on an actual system, design can first iterate through a simulator. This is particularly useful when test beds cannot be used, i.e. to explore hardware or scales that do not yet exist or are inaccessible. Here we detail the macroscale components of the structural simulation toolkit (SST). Instead of depending on trace replay or state machines, the simulator is architected to execute real code on real software stacks. Our particular user-space threading framework allows massive scales to be simulated even on small clusters. The link between the discrete event core and the threading framework allows interesting performance metrics like call graphs to be collected from a simulated run. Performance analysis via simulation can thus become an important phase in extreme-scale programming model and runtime system design via the SST macroscale components.
