A Decision Support Framework for Feasibility Analysis of International Space Station (ISS) Research Capability Enhancing Options

The assembly and operation of the ISS has generated significant challenges that have ultimately impacted resources available to the program's primary mission: research. To address this, program personnel routinely perform trade-off studies on alternative options to enhance research. The approach, content level of analysis and resulting outputs of these studies vary due to many factors, however, complicating the Program Manager's job of selecting the best option. To address this, the program requested a framework be developed to evaluate multiple research-enhancing options in a thorough, disciplined and repeatable manner, and to identify the best option on the basis of cost, benefit and risk. The resulting framework consisted of a systematic methodology and a decision-support toolset. The framework provides quantifiable and repeatable means for ranking research-enhancing options for the complex and multiple-constraint domain of the space research laboratory. This paper describes the development, verification and validation of this framework and provides observations on its operational use.

An overview of the Douglas Aircraft Company Aeroelastic Design Optimization Program (ADOP)

From a program manager's viewpoint, the history, scope and architecture of a major structural design program at Douglas Aircraft Company called Aeroelastic Design Optimization Program (ADOP) are described. ADOP was originally intended for the rapid, accurate, cost-effective evaluation of relatively small structural models at the advanced design level, resulting in improved proposal competitiveness and avoiding many costly changes later in the design cycle. Before release of the initial version in November 1987, however, the program was expanded to handle very large production-type analyses.

Deactivation of the K-27 building at the east Tennessee Technology Park - 15554

In 1942, nearly 24,280 hectares (60,000 acres) of east Tennessee landscape became part of the most significant defense strategy in the history of the United States - the Manhattan Project. Three methods of uranium separation were pursued at the site in the effort to end World War II. What became the K-25 site, now known as the East Tennessee Technology Park, focused on the gaseous diffusion method of uranium enrichment. This paper focuses on the deactivation of the second of five gaseous diffusion plants built on the site. The four-level, rectangular-shaped K-27 came online in 1945 and was tied to the site's original gaseous diffusion plant, K-25. K-27 extended K-25's enriching stages to increase production. The plant supported weapons production and other security strategies until 1964. K-27 spans 35,582 square meters (383,000 square feet) and contains approximately 92,903 square meters (one million square feet) of floor space. During deactivation, workers will use an assembly line process to tackle the 540 process stages housed in 90 cells. While often the less publicized, less visible aspect of building decontamination and decommissioning, deactivation takes more than three times longer than demolition. Crews work in high-risk, high-hazard environments - exposed to extreme temperatures, radiological and chemical contaminants, and deteriorating infrastructure. Therefore, worker safety becomes the most rigorous task performed. K-27 is the fifth and final gaseous diffusion building in the Department of Energy's Oak Ridge Environmental Management program to be demolished. (authors)

Perspectives on Previous DOE Transportation Acquisition Efforts - 19049

The Department of Energy (DOE) is planning for future large-scale transport of commercial Spent Nuclear Fuel (SNF) and High-Level Radioactive Waste (HLW) to eventual disposal and/or storage facilities. Various options for procuring transportation services are being evaluated. To inform this work, a review of past comments received on DOE transportation acquisition activities in the early 1990's through 2016 was conducted. Through the course of data collection, staff analyzed comments submitted from ten DOE initiatives from DoE's Office of Civilian Radioactive Waste Management (OCRWM) and DoE's Office of Nuclear Energy (DOE-NE). This paper summarizes and outlines key themes arising from these comments. Past issues identified by a wide variety of commenters (nuclear industry and cask vendors, nuclear utilities and purchasers, states, Tribes, local governments, rail carriers, nongovernmental organizations, trade organizations, engineering firms, and members of the public) were examined. These issues concerned DoE's activities to make maximum use of the private sector to transport and store SNF and HLW. The key themes analyzed include: Uniqueness of the Shipping Campaign, Views on Privatization, Industry Risk and Privatization, Unclear Roles and Responsibilities, and Responsibilities Recommended for DOE to Maintain. This paper concludes by discussing lessons that can be learned from analyzing these public comments and what that may mean moving forward in the U.S. radioactive waste management program. (authors)

Amine Swingbed Payload Project Management

The International Space Station (ISS) has been designed as a laboratory for demonstrating technologies in a microgravity environment, benefitting exploration programs by reducing the overall risk of implementing such technologies in new spacecraft. At the beginning of fiscal year 2010, the ISS program manager requested that the amine-based, pressure-swing carbon dioxide and humidity absorption technology (designed by Hamilton Sundstrand, baselined for the ORION Multi-Purpose Crew Vehicle, and tested at the Johnson Space Center in relevant environments, including with humans, since 2005) be developed into a payload for ISS Utilization. In addition to evaluating the amine technology in a flight environment before the first launch of the ORION vehicle, the ISS program wanted to determine the capability of the amine technology to remove carbon dioxide from the ISS cabin environment at the metabolic rate of the full 6-person crew. Because the amine technology vents the absorbed carbon dioxide and water vapor to space vacuum (open loop), additional hardware needed to be developed to minimize the amount of air and water resources lost overboard. Additionally, the payload system would be launched on two separate Space Shuttle flights, with the heart of the payload the swingbed unit itself launching a full year before the remainder of the payload. This paper discusses the project management and challenges of developing the amine swingbed payload in order to accomplish the technology objectives of both the open-loop ORION application as well as the closed-loop ISS application.

BuildingSync® [SWR-18-28]

BuildingSync® is a standardized language for commercial building energy audit data that software developers can use to exchange data between audit tools. Taking the form of an XML schema, BuildingSync can be required by building owners and audit program managers to allow data analysis and aggregation across multiple buildings in order to evaluate program performance and analyze trends. BuildingSync was developed using the standard energy data terminology defined in the Building Energy Data Exchange Specification (BEDES). BuildingSync is one of the first implementations of BEDES Version 1.0, and it was developed in close collaboration with the BEDES working groups. BuildingSync standardizes the format of the energy audit data itself. It is not intended to standardize the calculations performed on these data by engineers, analysts, software packages, or other audit tools. For more, see: https://buildingsync.net/

Technology as a driver for improved space products

Technology development is frequently undertaken by research groups which are independent of program organizations, and then the difficult task is faced some time during the program development of selecting the technology level which will meet the program's needs. This paper examines that process and suggests an approach which helps to establish the 'right' technology level and conditions under which the technology will actually be introduced into the program. The paper recommends that a technology insertion milestone be formally established to select the technologies or technology levels which will be incorporated during hardware development. The Technology Insertion Milestone should be a program event, and it should occur shortly before the design and development phase. Working with the program office, technology options can be presented and their payoff estimated for the program. Coupled with that appraisal should be a definition of the activity necessary to bring the technology options to the point where the program management would commit to its usage with confidence. Examples are given of two NASA programs, Pluto Fast Fly-By and TIMED, where the Technology Insertion Milestone process has been established and is underway.

Human Error Analysis for Human-Rated Space Systems

Humans bring unique capabilities to space systems and contribute to mission success in a manner that cannot be matched by machines. Nevertheless, from time to time, human error can present a threat to system performance, and system designers must anticipate and manage this risk. NASA’s Human-Rating Requirements for Space Systems call for program managers to conduct a human error analysis (HEA) during system development but does not specify how to do this. In 2018, NASA’s Engineering and Safety Center asked the authors to develop a guidance document on HEA. The resulting position paper outlines a suggested method for HEA and makes it clear that error analysis is about identifying and mitigating problems at a system level, and not about finding fault with individuals. Error management strategies must be directed at error-producing conditions, thereby reducing the likelihood of human error, while retaining the positive contribution that humans make to system operations.

Spectroscopic Characterization of Tc(I) Tricarbonyl Species Relevant to the Hanford Tank Waste - 17379

Technetium-99 (Tc) generated from the fission of {sup 235}U and {sup 239}Pu in high yields is one of the most difficult contaminants to be addressed at the U.S. Department of Energy (DOE) Hanford Site. Among radioactive contaminants, Tc presents a unique challenge in that it has a long half-life (T{sub 1/2} = 2.11x10{sup 5} y), exhibits diverse chemical properties and typically highly mobile in the environment leading to several uncertainties regarding treatment and disposition options. The complex behavior of Tc under storage, treatment, and immobilization conditions significantly affects its management options. The overall objective of the Technetium Management program at Pacific Northwest National Laboratory is to provide the DOE Office of Environmental Management with practical solutions to Tc needs encountered in the processing of Hanford tank waste and vadose zone remediation; and technical activities are being performed in the areas of Tc characterization, treatment, and disposition. One specific task is focused on elucidation of the identity and properties of non-pertechnetate species in the liquid Hanford tank waste. Previous analysis of the tank waste samples provided strong evidence that non-pertechnetate species can be comprised of Tc(CO)3+ complexes containing Tc in oxidation state +1. This paper describes our current results on the development of spectroscopic library of Tc(I) tricarbonyl species for their characterization and identification in the Hanford tank wastes. (authors)

Receiver willingness to participate in off-hour service programs

Service trips, a frequently overlooked segment of urban traffic, represent a disproportionately large share of the negative impacts associated with commercial activity. The reason is that although service trips are less frequent than freight trips, they often take longer and thus occupy a significant share of commercial parking. Demand management programs seeking to move service trips off-hours can potentially reduce congestion and emissions but they have been understudied. Here, this paper describes research conducted to investigate receivers’ willingness to participate in off-hour programs for planned service activity. The research reported in this paper analyzes results from a survey of 189 business establishments in New York City and the Capital Region in New York State using descriptive analyses of the data, and by estimating a discrete choice model to gain insight into how business characteristics influence willingness to participate in off-hour services. To assess the impacts of a hypothetical off-hour services program, the authors applied the discrete choice model, together with service trip attraction models, to quantify the hours of daytime parking that could be eliminated by the proposed program in certain ZIP Codes in New York City and the Albany area. The research conducted led to the identification of numerous policy implications that will help policymakers understand and maximize the potential benefits of implementing off-hour service programs.

NASA's Radioisotope Power Systems Program Status

NASA's Radioisotope Power Systems (RPS) Program began formal implementation in December 2010. The RPS Program's goal is to make available RPS for the exploration of the solar system in environments where conventional solar or chemical power generation is impractical or impossible to meet mission needs. To meet this goal, the RPS Program manages investments in RPS system development and RPS technologies. The current keystone of the RPS Program is the development of the Advanced Stirling Radioisotope Generator (ASRG). This generator will be about four times more efficient than the more traditional thermoelectric generators, while providing a similar amount of power. This paper provides the status of the RPS Program and its related projects. Opportunities for RPS generator development and targeted research into RPS component performance enhancements, as well as constraints dealing with the supply of radioisotope fuel, are also discussed in the context of the next ten years of planetary science mission plans.
