KAERI Underground research tunnel (KURT) - phase II activities for HLW disposal technology development in Korea - 15253

Phase I construction of the KAERI Underground Research Tunnel (KURT), a small-scaled underground research facility, was completed in November 2006. Since then various in-situ tests and experiments at KURT for phase I have been carried out to develop safe and reliable disposal techniques for high-level radioactive waste in a deep geological formation. The KURT extension project was approved by the Korean government in 2012 and the design of the tunnel layout and construction methods were decided by early 2013. Site investigation and installation of a monitoring system for the extension were completed by Oct. 2013. The construction activity was started from December 2013 and will be completed by the end of 2014. Phase II experiments in KURT will be carried out for the next 10 years. KURT continues to play a significant role in validating the safety and feasibility of a deep geological disposal system in the research program in Korea. (authors)

Rapid Development of Disruptive Photovoltaic Technologies

Development of new PV technologies based on novel materials is an important direction of solar cell research to enhance the odds for beyond-TW scaling of solar energy production. However, such research presents a significant technical challenge, because it requires a balance between sufficient breadth (screening new materials) and depth (development of PV devices) of the problem. The objective of this project was to establish novel inorganic photovoltaic absorbers using rapid development approach. The studied materials were the potentially scalable defect-tolerant oxide- and nitride solar cell absorbers. For one of these materials (ZnSnN 2 ), we have experimentally demonstrated how to achieve low carrier density required for solar cell fabrication, and demonstrated that this synthesis process leads to near band edge photoluminescence supporting high optoelectronic quality of the material. For this ZnSnN 2 material, we also showed that cation disorder does not significantly influence carrier transport, and that benign defect complexes can lead to improved doping control, both supporting the targeted defect tolerance of this material. All these results have been summarized in peer review publications, some featured on journal covers. In addition, we established a new class of anti-perovskite absorbers, and published several review articles of the field.

Full Scale Engine Demonstration of Additively Manufactured High Gamma Prime Turbine Blade

Additive manufacturing (AM), also known as 3D printing, is a rapidly developing technology with tremendous potential in both developmental and production applications. Solar Turbines Incorporated is committed to AM technology development for gas turbine applications. The ability to metal 3D print novel designs of turbine blades capable of actual turbine engine operation would effectively reduce design validation cycle time and allow acquisition of key performance data early in a design campaign. In support of Solar’s advanced manufacturing development and ongoing engine efficiency improvement goals, ORNL and Solar conducted a project to 3D print, machine, inspect, and engine test a full set of Mercury TM 50 stage 2 turbine blades. This full-scale, hot-fired engine demonstration has identified both the capabilities and limitations of the current technologies required to produce turbine hot-section AM components.

A Review of Underground Coal Gasification Research and Development in the United States

An intense and productive period of research and development on underground coal gasification (UCG) took place in the United States from the mid-1970’s through the late 1980’s. It began with the translation and review of Soviet literature and ended with the Rocky Mountain 1 field test. This demonstrated the feasibility of newly-developed technologies that form the basis of many UCG projects around the world today. This period began with little domestic understanding of UCG and ended with an accurate observation-based conceptual model and a corresponding predictive multi-physics mathematical model of the process. The many accomplishments of this period form the main content of this report. This report also covers recent U.S. activities and accomplishments during the period 2004-2015, and touches briefly on the Bureau of Mines efforts between 1948 and 1963. Most of the activities were funded by the United States Department of Energy and its predecessors. While private/commercially-funded activities are reviewed here, the emphasis is on government-funded work. It has a much greater extent of publicly available reports and papers, and they generally contain much greater technical detail. Field tests were the marquis activities around which an integrated multi-faceted program was built. These are described in detail in Section 4. Highlights from modeling efforts are briefly covered, as the program was integrated and well-rounded, with field results informing models and vice-versa. The primary goal of this report is to review what has been learned about UCG from the U.S. experience in aggregate. This includes observations, conclusions, lessons-learned, phenomena understood, and technology developed. The latter sections of this report review these things.

Hydropower Capital and O&M Costs: An Exploration of the FERC Form 1 Data

This report explores the potential for using responses from the Federal Energy Regulatory Commission’s (FERC’s) “Electric Utility Annual Report,” also known as FERC Form 1, as a cost database for conventional and pumped storage hydropower (PSH). The report outlines the process used to compile an easy-to-access database from the original FERC Form 1 data and discusses the historical cost/performance data. The steps for developing the database include downloading the annual FoxPro files from the FERC website (FERC, 2020), reading them into an Excel format, and reconciling naming issues across years, repeated entries, and shared assets, among others. The cleaned and compiled Form 1 database is available on Oak Ridge National Laboratory’s (ORNL’s) HydroSource website. For this report, the compiled Form 1 database was linked to two other hydropower databases, the National Inventory of Dams and the ORNL Existing Hydropower Assets, that provide additional information on the characteristics and other features of plants in the Form 1 data. Explorations of the plant characteristics, performance, capital costs, and operation and maintenance (O&M) cost data in the combined database were presented separately for conventional hydropower and PSH projects. Form 1 has several advantages as a hydropower cost database. First, the cost data is reported directly by plant owners. Second, Form 1 provides cost breakdowns of capital and operating costs for large conventional and PSH plants enabling more detailed tracking of hydropower costs compared with typical total cost estimates. Third, although the Form 1 data is not reported by all operational hydropower plants in the United States, the available data represents a wide range of plant characteristics and a sizable proportion of the hydropower fleet (61% of PSH plants and 22% of conventional hydropower plants by capacity). The lower proportion of the conventional hydropower fleet is because Form 1 reporting requirements apply only to private utilities that meet given size thresholds, leaving out federally owned facilities and many smaller hydropower plants. Overall, the Form 1 cost database represents a unique, publicly available database on hydropower asset capital and O&M costs. This report leads to a compiled database for the reporting years 1994 to 2020 that helps resolve issues with accessibility and use of the FERC Form 1 data by hydropower plant owners, project developers, technology developers, and regulators.
