NRIC Strategy for Advancing Nuclear Integrated Energy Systems

Integrated energy systems (IES) combine low-carbon energy sources to meet demand for clean energy in multiple forms across multiple sectors of economy. IES create opportunities to cost-effectively dispatch generation resources to balance electricity supply and demand. In addition to producing electricity, IES increase the value of non-emitting energy sources by integrating generation technologies with industrial processes to efficiently produce commodities that benefit the manufacturing, industrial processing, and transportation industries. Nuclear energy technology is key to enabling these benefits. Advanced nuclear reactors capable of producing high-quality heat, electricity, and radiation, will play a foundational role in IES of the future.

Methods, apparatus and systems for generating and superheating vapor under sunlight

A solar vapor generator includes an absorber to absorb sunlight and an emitter, in thermal communication with the absorber, to radiatively evaporate a liquid under less than 1 sun illumination and without pressurization. The emitter is physically separated from the liquid, substantially reducing fouling of the emitter. The absorber and the emitter may also be heated to temperatures higher than the boiling point of the liquid and may thus may be used to further superheat the vapor. Solar vapor generation can provide the basis for many sustainable desalination, sanitization, and process heating technologies.

Industrialized and Robotic Construction Advances in Terrestrial Construction and Opportunities in Space Construction

Advanced Building Construction (ABC) methods such as industrialized prefabrication and robotically controlled additive deposition are becoming promising technologies to support rapid construction of buildings at volume and scale. However, apart from the structural shell of the building, optimal integration of other systems – mechanical, electrical, plumbing, thermal, power generation, storage and distribution, is key to enabling functional buildings. Leveraging ABC methods to integrate such systems in the buildings requires the building design to be optimized for constructability constraints imposed by the industrialized and robotically controlled production setups entailing such ABC methods. The Industrialized Construction Innovation (ICI) team at the National Renewable Energy Laboratory (NREL) has been focusing on research and development of such ABC technologies and processes that can lead to production of buildings which are resilient to extreme climatic conditions at reduced cost and time. There is a potential synergy between such advancements in terrestrial construction, which can be leveraged for the benefit of space (orbital and extra-terrestrial) construction. Similarly, advances in space construction can lend itself to accelerated adoption of robotic construction methods in terrestrial construction. This presentation will give an overview of selective research efforts of the ICI team at NREL, along with a vision for potential collaborations with agencies like NASA.

Invite the Chaos Monkey: Test Effect Payloads for Tuning ICS Incident Response

In 2010, when Netflix moved their operational systems to the cloud, they developed a pseudo-random mechanism to cause deliberate outages and failures of key system elements to ensure that automated systems for detecting and remediating outages were mature and fully functional. This Chaos Monkey spawned an entire Simian Army designed to ensure system resilience and enable failure response before issues became outages. Through the DARPA RADICS program, Provatech, INL, and other researchers have developed a mechanism for creating controllable failures via Test Effect Payloads (TEPs) for Industrial Control Systems in order to enable an asset owner to tune network and process sensor technology, increase the effectiveness of incident response and remediation, and highlight areas where resilient technology could bring benefit to Operational Technology. This talk will explore what a TEP is, how to create a TEP, and suggest what a systematic system resilience plan using TEP’s might look like. We will also discuss how regulated entities might employ TEP’s in a compliant resilience strategy.

Training and Mentoring the Next Generation of Scientists and Engineers to Secure Continuity and Successes of the US DOE's Environmental Remediation Efforts - 13387

The DOE Office of Environmental Management (DOE-EM) oversees one of the largest and most technically challenging cleanup programs in the world. The mission of DOE-EM is to complete the safe cleanup of the environmental legacy from five decades of nuclear weapons development and government-sponsored nuclear energy research. Since 1995, Florida International University's Applied Research Center (FIU-ARC) has supported the DOE-EM mission and provided unique research capabilities to address some of these highly technical and difficult challenges. This partnership has allowed FIU-ARC to create a unique infrastructure that is critical for the training and mentoring of science, technology, engineering, and math (STEM) students and has exposed many STEM students to 'hands-on' DOE-EM applied research, supervised by the scientists and engineers at ARC. As a result of this successful partnership between DOE and FIU, DOE requested FIU-ARC to create the DOE-FIU Science and Technology Workforce Development Initiative in 2007. This innovative program was established to create a 'pipeline' of minority STEM students trained and mentored to enter DOE's environmental cleanup workforce. The program was designed to help address DOE's future workforce needs by partnering with academic, government and private companies (DOE contractors) to mentor future minority scientists and engineers in the research, development, and deployment of new technologies and processes addressing DOE's environmental cleanup challenges. Since its inception in 2007, the program has trained and mentored 78 FIU STEM minority students. Although, the program has been in existence for only five years, a total of 75 internships have been conducted at DOE National Laboratories, DOE sites, DOE Headquarters and field offices, and DOE contractors. Over 85 DOE Fellows have participated in the Waste Management Symposia since 2008 with a total of 68 student posters and 7 oral presentations given at WM. The DOE Fellows participation at WM has resulted in three Best Student Poster Awards (WM09, WM10, and WM11) and one Best Professional Poster Award (WM09). DOE Fellows have also presented their research at ANS DD and R and ANS Robotics Topical meetings. Moreover, several of our DOE Fellows have already obtained employment with DOE-EM, other federal agencies, DOE contractors. This paper will discuss how DOE Fellows program is training and mentoring FIU STEM students in Department of Energy's Office of Environmental Management technical challenges and research. This training and mentoring has resulted in the development of well trained and polished young scientists and engineers that will become the future workforce in charge of carrying on DOE-EM's environmental cleanup mission. The paper will showcase FIU's DOE Fellows model and highlight some of the applied research the DOE Fellows have conducted at FIU's Applied Research Center and across the Complex by participating in summer internship assignments. This paper will also present and highlight other Fellowships and internships programs sponsored by National Nuclear Security Agency (NNSA), DOE-EM, NRC, Energy (NE), and other federal agencies targeting workforce development.

Commissioning and Operation of a Robotic Arm for Waste Retrieval at Trawsfynydd NPP, North Wales - 12091

Trawsfynydd is one of the UK's first generation Magnox nuclear power plants. It started operation in 1965 and ceased generation in 1991. Before the site can enter the 'care and maintenance' phase a number of wet and dry waste stores around the site must be emptied and their contents made safe. Wet wastes include sludges and resins produced during the operating life of the NPP. The sludges and resins are stored in a number of different tanks that vary significantly in terms of size, shape, internal features and access. A dexterous long reach manipulator arm has been designed and built to facilitate tank clearance. Commissioning of the arm was carried out in parallel with Factory Acceptance Testing (FAT) at the manufacturer's site in Colorado, USA. In addition to basic functional testing this work included a full range of task based testing to ensure that the arm, tools, control system and support equipment were thoroughly exercised in representative conditions. Trawsfynydd is one of the lead sites in the UK's program for nuclear plant decommissioning. As such the lessons learned, both in terms of technology and process, will be applicable across the remainder of the fleet. (authors)

EPRI Report: Guidance in the Use of Robotics and Automation for Decommissioning Nuclear Power Plants - 17440

In the coming ten years, approximately 100 commercial nuclear power plants will be shut down worldwide, adding to the fifty nuclear power plants already shut down that have not yet entered into decommissioning. Just under a half of the overall cost of decommissioning a nuclear power plant is utility staffing costs (costing approximately 20 million USD per year of the decommissioning project), with waste and dismantlement costs making up the remainder. Decommissioning across the globe is being executed largely by manual labor. Some overview organizations such as OECD have concluded that the nuclear industry has not fully exploited or implemented current technological capabilities, and relies on outdated technology to perform decommissioning tasks. The use of more efficient and effective decommissioning technologies and processes could reduce the decommissioning project schedule and therefore the $20 M/year staffing costs incurred throughout the decommissioning project life. Such systems may also offer a substantial benefit with respect to worker safety and exposure reduction. However, tasks for which use of such systems is beneficial must be carefully considered. The systems themselves need to be robust and generally trouble free to operate in the demanding environment of commercial power plant decommissioning. EPRI is preparing a report, Guidance in the Use of Robotics and Automation for Decommissioning Nuclear Power Plants, which documents approaches that can perform decommissioning work in a safe and ALARA manner while reducing the overall cost to decommission a nuclear power plant.

Ensuring NQA-1 Compliance with Nuclear Next Gen Technologies Performing a Safety Function Associated with Autonomy or Remote Systems - 17549a

First-of-a-kind and cutting edge Next Gen technologies deployed in a nuclear environment may initially appear to fall outside the ability to be qualified in accordance with ASME NQA-1 for a nuclear safety function. However, NQA-1 compliance is possible especially if baked into the early stages of the technology development process. This is particularly applicable as part of the increasingly prevalent application of autonomous processes, advanced manipulation, man-machine interfaces, exoskeletons and other advanced and unique ability options.

Technology Maturation in Support of DOE 413.3B Project Execution - 16436

The DOE Order 413.3B 'Program and Project Management for the Acquisition of Capital Assets' provides program and project management direction for the acquisition of capital assets with the goal of delivering projects within the original performance baseline (PB), cost and schedule, and fully capable of meeting mission performance, safeguards and security, and environmental, safety, and health requirements. Execution of complex DOE 413.3B projects depends, in part, upon the successful integration of a technology maturation program. The Low Activity Waste Pre-Treatment System (LAWPS) is executing a detailed technology maturation program under the Technology Readiness Level/Technology Maturation Plan (TRL/TMP) guidance of DOE Order 413.3B. The interaction of the technology maturation process and the project execution including technical, programmatic, and contractual execution, has been a critical component for project success.

Automation and Use of Robotics for Decommissioning Tasks - 18322

Decommissioning across the globe is being executed largely by manual labor. The Organization for Economic Co-operation and Development (OECD) has concluded that the nuclear industry has not fully exploited or implemented current technological capabilities, and relies on sometimes outdated technology to perform decommissioning tasks [1]. To address this issue, EPRI recently published the report Evaluation of System Automation and Robotics for Decommissioning Applications (EPRI 3002010599) [2]. To facilitate wide usage of the guidance by technology developers, the report is publicly available at no cost. The use of more efficient and effective decommissioning technologies and processes could reduce the decommissioning project schedule and therefore reduce the period-dependent costs incurred throughout the decommissioning project. Such systems may also offer a substantial benefit with respect to worker safety and radiation exposure reduction. However, tasks for which use of such systems is beneficial must be carefully considered, being robust and generally trouble free to operate in the demanding environment of commercial power plant decommissioning. A review of the major tasks involved in the decommissioning of a nuclear power plant is presented, with a critical assessment of the benefits for the use of robotics and/or automation. Recommendations for areas of future research and development are identified. The results of this project will be beneficial to global organizations working on development of engineered systems for decommissioning applications by providing a focus on priority tasks. (authors)

La Hague STE2 Sludge Retrieval and Conditioning Strategy - 19229

About 9000 m{sup 2} of Long-Lived Intermediate Level Waste LL-ILW STE2 sludges have been generated by the reprocessing operations of UNGG and later UOx fuel in La Hague (UP2-400) and subsequent liquid effluent treatment. They were placed into a set of adjoining tanks, called the STE2 silos. Today, the STE2 Sludges have to be retrieved and conditioned for final disposal in the deep geological repository under development in France (Cigeo). To this end, since the early 2000's, different retrieval and conditioning scenarios have been evaluated. This paper tracks the history of the technical and non-technical key factors having led to the choice of the baseline scenario developed until the end of 2016, describes the technical achievements and makes a state-of the art of the current scenario consisting in retrieving and temporarily storing STE2 sludges and, meanwhile, studying, researching and testing final conditioning processes and technologies in the aim of achieving a technical and economic optimum.
