The premature cessation of operations at several large commercial reactors in the United States has created for the owners of these facilities an accelerated liability for decommissioning. A majority of the owners of these facilities, however, still elected to proceed with immediate dismantling, even though, in many instances, the adequacy of the available funding had not been established. With limited financial resources, project success often depends upon the ability of the owner to address and resolve project encumbrances, regulatory constraints and the growth of the work scope in an expeditious and cost-effective manner. The common lesson-learned recognized in the performance of these major projects over the last 15 years, is that planning for decommissioning needs to be started earlier and include a comprehensive cost analysis so as to facilitate post-shutdown activities. This paper will summarize the processes used to identify and quantify decommissioning liabilities in the US, as well as in other countries. In particular, the objectives in developing a cost estimate will be explored, the types of estimates discussed, and the need to integrate the estimate within the ongoing planning for decommissioning. Strategic cost considerations will be identified, as well as their impact on the financial resources required. Case studies will be presented, identifying both similarities and differences in purpose and in scope. The paper will discuss the key planning tools, for example, facility characterization assessments for radiological, hazardous and toxic contaminates. Program management is the single largest expense incurred in plant decommissioning since it is a highly regulated and controlled process. However, in most instances, the oversight of decommissioning operations requires only a fraction of the original operating organization. This paper will explore the need to streamline and transition the operating staff to one that can effectively support decommissioning activities while minimizing the overall expense. Waste conditioning and disposal is a major technical, as well as financial element, in the facility decommissioning. The availability and cost of regional and national disposal facilities is a key consideration in the options selected for decommissioning, including timing, approach and methods selected. The formation and integration of a waste management strategy will be discussed along with the sensitivity of the decommissioning cost and schedule to the strategy selected. The paper will conclude with several observations relating to the need to include financial planning in any decommissioning evaluation, a discussion of lessons-learned from ongoing decontamination and dismantling projects, and common misconceptions. Recommendations will be offered for owners of those facilities currently considering decommissioning, as well as those in the early planning stage.

American Catholicism has long adapted to US liberal institutions. Progressive Catholicism has taken the liberal values of democratic participation and human rights and made them central to its interpretation of Catholic social teaching. This chapter explores in detail the thought of David Hollenbach, S.J., a leading representative of progressive Catholicism. Hollenbach has proposed an ethical framework for an economy aimed at the common good, ensuring that the basic needs of all are met and that all are able to participate in economic life. The chapter also looks at the US Catholic bishops’ 1986 pastoral letter Economic Justice for All, which emphasizes similar themes while also promoting collaboration between the different sectors of American society for the sake of the common good.

India is currently the world’s third-largest emitter of greenhouse gases (GHGs) after China and the United States and is set to experience continued growth in its population, economy, and energy consumption. Exploring low-carbon development pathways for India is therefore crucial for achieving the goal of global decarbonization. India has pledged to reduce the emission intensity of its gross domestic product (GDP) by 33–35 per cent relative to 2005 levels by 2030 through its Nationally Determined Contribution (NDC), among other related targets for the renewable energy and forestry sectors. Further, countries, including India, are expected to respond to the invitation of the Conference of the Parties (COP) to the Paris Agreement to communicate new or updated NDCs with enhanced ambition and long-term low-GHG development strategies for 2050. To design effective policy packages to support the planning and achievement of such climate targets, policymakers need to identify policies that can reduce GHG emissions in a timely and cost-effective manner, while meeting development-related and other national objectives. The India Energy Policy Simulator (India EPS), an open-source, system dynamics model, can enable an integrated quantitative assessment of different cross-sectoral climate policy packages for India through 2050 and their implications for key variables of interest such as emissions, GDP, and jobs. The tool was developed by Energy Innovation LLC and adapted for India in partnership with World Resources Institute. It is available for open access through a Web interface as well as a downloadable application. This technical note describes the structure, input data sources, assumptions, and limitations of the India EPS, as well as the setup and key results of its reference scenario, referred to as the business-as-usual (BAU) scenario in the model. It is intended as an update to the first technical note on the India EPS (Mangan et al. 2019) and accounts for the changes incorporated into the model since the first version.

Deconstruction is the selective dismantling of building structures to recover the maximum amount of primarily reusable and secondarily recyclable materials in a safe and cost-effective manner. Deconstruction is a labor intensive process and can be difficult to achieve in a time-efficient and economical manner for light wood-framed buildings. Deconstruction techniques that balance hand and mechanical labor must be developed to maintain the integrity of materials for reuse and obtain maximum salvage value per unit of cost and time-on-site. This project entailed the removal of three identical WWII-era two-story wood-framed barracks buildings at Ft. McClellan Army Base, Anniston, AL, using hand deconstruction, combined mechanical and hand deconstruction techniques, and a traditional demolition method, i.e., mechanical reduction and disposal, in order to determine “optimal” deconstruction techniques based on salvage value per unit of cost. The maximum practical materials salvage from the study buildings using 100% hand deconstruction techniques was 39% of the mass by weight. A combination of hand and mechanical techniques was discovered to have approximately the same economic efficiency as 100% hand deconstruction, measured as a ratio of gross cost per salvage value, with a 44.6% reduction in total labor-hours, and a reduction of only 7% of salvage materials by weight. These findings indicate the potential for greatly increasing wood-framed building deconstruction practice relative to the additional time-on-site and labor that is required, compared to demolition, while optimizing economic benefits. This paper describes the research methods and deconstruction techniques employed, and lessons learned to advance the practice of deconstruction to be more economically competitive and time-efficient.

The use of taxes to elevate the price of popular commodities in order to reduce consumption and risks related to use did not originate with carbon taxes. Excise taxes on tobacco have been used aggressively by governments in the United States and beyond in recent decades to achieve significant reductions in smoking. Fossil fuel use has long been deemed by diverse economists as a viable target for a sequel, leading to innumerable reports and scholarly arguments making the case for a carbon price. This can take the form of either a direct tax on the carbon content of fossil fuels or a cap-and-trade system that allows for purchase of rights to release emissions at a price. Both are thought to offer effective paths to reduce emissions in a cost-effective manner.

Key lessons can be made from analysing a unique and recent BIT, the Canada–China Foreign Investment Protection Agreement (FIPA), in order better to predict and identify the opportunities and challenges for potential BIT counterparties of China (such as the United States, the European Union (EU), India, the Gulf Cooperation Council, and Columbia). The Canada–China FIPA and the anticipated US–China BIT (and EU–China BIT) collectively fall into a unique class of investment agreements, in that they represent a convergence of diverse ideologies of international investment norms/protections with two distinct (East/West) underlying domestic legal and economic systems. The purpose of this chapter is to appreciate and utilize the legal content of the Canada–China FIPA in order to isolate the opportunities and challenges for investment agreements currently under negotiation (focusing on the US–China BIT). This analysis is conducted from the perspective of China’s traditional BIT practice and political–economic goals, relative to that of its counterparty. This chapter briefly addresses the economic and broader diplomatic relationship between China and Canada, comparing that with the United States. It then analyses a broad selection of key substantive and procedural obligations of the Canada–China FIPA, addressing their impact, individually and cumulatively, to extract what lessons can be learned for the United States (US) and other negotiating parties. This analysis identifies the degree of investment liberalization and legal protection that Canada and China have achieved, and whether these standards are reciprocally applied. The analysis is not divorced from the relevant political economy and negotiating position between China and the counterparty and the perceived economic benefits of each party, as well as any diplomatic sensitive obstacles between the parties. While this chapter does not exhaustively analyse each substantive and procedural right, it provides enough of a comprehensive basis to reveal those challenges that remain for future bilateral negotiations with China.

The 2017 Atlantic hurricane season had 17 named storms, 10 hurricanes, and 6 major hurricanes, generating over 226 units of accumulated cyclone energy (ACE), a measure used by the National Oceanographic and Atmospheric Association (NOAA) that refers to the combined the intensity and duration of a hurricane. These statistics earned the hurricane season’s classification as “extremely active,” the most active since 2005. Preliminary estimates of damage due to Hurricanes Harvey, Irma, and Maria amount to over $200 billion dollars in the United States alone. Recent studies suggest that the frequency of these high intensity Category 4 and 5 hurricanes is increasing (e.g. Mendelsohn et al., 2012). The 2017 hurricane season may thus be representative of an expected season. Accounting for projected increases in mean sea level, storm impacts may be exacerbated in coastal regions. These trends emphasize the need for effective damage mitigation techniques that improve the robustness and resiliency of coastal communities. Structures must be designed to not only avoid wave and surge loads, but also resist these forces in the event of a wave impact. Furthermore, creative, cost-effective solutions are required to mitigate waves and surge before they reach developed coastal areas. Thus, engineers require a robust, science-based methodology for predicting details of wave propagation over land and inland effects to ensure life safety and reduce economic loss due to extreme events. While traditional engineering strategies (e.g. seawalls, bulkheads) have been used to prevent coastal erosion and mitigate inland effects of hurricane waves and surge, recent storm events have shown potential of nature and natural based features (e.g. dune vegetation, mangroves, wetlands, salt-marshes, coral reefs, and seagrass) to protect coastal structures during storm events.

Much of the United States’ critical infrastructure is either aging or requires significant repair, leaving U.S. communities and the economy vulnerable. Outdated and dilapidated infrastructure places coastal communities, in particular, at risk from the increasingly frequent and intense coastal storm events and rising sea levels. Therefore, investments in coastal infrastructure are urgently needed to ensure community safety and prosperity; however, these investments should not jeopardize the ecosystems and natural resources that underlie economic wealth and human well-being. Over the past 50 years, efforts have been made to integrate built infrastructure with natural landscape features, often termed “green” infrastructure, in order to sustain and restore valuable ecosystem functions and services. For example, significant advances have been made in implementing green infrastructure approaches for stormwater management, wastewater treatment, and drinking water conservation and delivery. However, the implementation of natural and nature-based infrastructure (NNBI) aimed at flood prevention and coastal erosion protection is lagging. There is an opportunity now, as the U.S. government reacts to the recent, unprecedented flooding and hurricane damage and considers greater infrastructure investments, to incorporate NNBI into coastal infrastructure projects. Doing so will increase resilience and provide critical services to local communities in a cost-effective manner and thereby help to sustain a growing economy.

The development of the adhesive bonding of the wing of the SAAB 340 and 2000 aircraft is traced from the development of the technology during the Primary Adhesively Bonded Structure Technology (PABST) research programme performed at Douglas Aircraft under contract to the US Air Force Wright Laboratories in the late 1970s through initial fabrication by Fairchild in America in the early 1980s to series production by SAAB in Sweden and, today, also by CASA in Spain. The saga of solving a processing problem encountered in America before the first aircraft was delivered is recounted as an object lesson in how to approach problems and in the benefits derived by doing so promptly and thoroughly. Every aspect of the problem was identified and replicated in the laboratory where, because it was understood properly, it could be duplicated and prevented at will. The lessons learned about bonding tool designs from this investigation and during the manufacture of the PABST fuselage were implemented during the transfer of production of the wing from America to Sweden. The use of a floating caul plate, rather than a traditional rigid bonding tool, is explained. The justification for doing so is the virtual elimination of all fit problems and the production of a far more uniform void-free bond line. In addition, the evolution of progressively simpler, yet more effective, bagging procedures is also described, culminating in a refinement of a technique pioneered by Fokker in Holland. Today, all breather and bleeder layers have been eliminated. This reduces costs and the need for disposal of costly expendable materials and also permits a positive check of the fit of the details by visual examination through the transparent bag once the vacuum is drawn before the assembly is inserted into the autoclave, giving an opportunity to correct any misfits while it is still possible to do so. Consequently, there is also no need for traditional verifilm operations. The tooling technology developed during the PABST programme did not die when the contract was completed with no follow-on production programme for large transport aircraft in the United States. It is alive and flourishing in Sweden. In addition, as the paper describes, the transfer of the technology was so complete that it has since been improved upon. Today, the bonding of the stiffened wing skins for these two aircraft is probably the most advanced and simultaneously the most forgiving production application of large-scale metal bonding the world has yet seen.

The lifetime risk of a woman developing breast cancer has increased over the past 5 years in the United States: of every 7 women, 1 is at risk based on a life expectancy of 85 years. An estimated 214,640 new cases (212,920 women and 1,720 men) of breast cancer and 41,430 deaths (40,970 women and 460 men) from this disease will occur in the United States in 2006. However, mortality from breast cancer has decreased slightly, attributed partly to mammographic screening. Early detection and accurate diagnosis made in a cost-effective manner are critical to a continued reduction in mortality. These practice guidelines are designed to facilitate clinical decision making. For the most recent version of the guidelines, please visit NCCN.org

With the end of the Cold War, much attention has been paid to the nature of the emerging new world order. By what criteria will power and influence be measured in this new era? Who will be the winners and losers? What types of allegiances will develop? Or is Francis Fukuyama's argument correct that, with the collapse of communism, we have reached the "...endpoint of man's ideological evolution" and thus "the end of history". Unlike Marx, who saw socialism at the end of humanity's arduous journey, Fukuyama tells us that the search is off because we have already arrived at our evolutionary destination: liberal capitalism...Other analysts envision less optimistic scenarios...One of the most popular scenarios over the past few years has been to anticipate growing tensions between the three main core powers: the US, Germany, and Japan... The first task of this paper, then, is to look at Germany within the context of the radically altered post-Cold War period... We argue that Germany, based on a multitude of factors which will be outlined below, is not now, nor will it ever become in the foreseeable future, a global hegemon... Indeed, as will be asserted in the second part of this paper, Germany will enter into a close alliance with the United States to form a reinvigorated trans-Atlantic marriage in which the common bonds of "culture and civilization" will replace a virulent anti-communism as the common vow.
