Book excerpt: A simple empirical model of activity and crud transport in the candu hts has been developed and its utility illustrated using station data. the model emphasizes the fundamental role played by the out-of-core deposits. the input parameters required by the model can be obtained from data from station artefact characterizations, radiation field measurements and oxi-probe measurements and single-tube decontaminations. the details of the model are illustrated using the "simple" example of 95zr transport, which is transported mainly as particles. the more challenging case of 60co transport is then used to highlight additional aspects of the model and to point out some of the areas where further work is required. the model provides insights into the effectiveness of the candu purification system. it has allowed order of magnitude estimates to be made of the effective deposition half-lives for radionuclide removal by the hts deposits; in particular: ? t1/2 (95zr) = 10 - 98 h ? t1/2 (60co) = 7 -62 min typical candu purification half-lives range from 50 minutes to several hours. this is short enough to compete effectively with hts surfaces for 95zr removal. at the highest flow rates, the one-hour half-life is short enough to have a measurable impact on 60co deposition; at longer purification half-lives, the impact on 60co deposition is likely small. it should be noted that 95zr is transported and deposited mainly as particles, while 60co is deposited mainly as a dissolved species. further work is required to determine if these half-lives can be generalized to all particulate and dissolved species. the model leads to an estimate for the efficiency of the main hts system for the removal of the different radionuclides from the circulating coolant. for 60co, this removal efficiency is in the range 0.28 to 2.5%. in most discussions of the purification system effectiveness, an implicit assumption has been that the hts deposits were highly efficient in removing dissolved species from the coolant. these values illustrate the error of that assumption. while the purification system receives only a very small flow compared to the steam generators (on the order of 0.1%), it is highly efficient (95 -100%). the main hts loop receives 99.9% of the flow, but is inefficient (on the order of 1%). the net result is that the two removal mechanisms are more closely matched than previously assumed. the pseudo-efficiency provides a link between this model and more mechanistic treatments of activity deposition. the hts deposit "full flow purification system" can be broken into components: outlet feeders, steam generators, inlet feeders. the utility of this sub-division has been demonstrated by calculating the effect of removing the steam generator deposits by decontamination on reactor face fields in the year immediately following the decontamination. the predicted factor of 3.0 increase in 60co deposition at the reactor face compares favourably with the increase observed at gentilly-2 after the siva-blast of a factor of 2.8. refinements to the model should enable the pseudo-efficiencies to be linked to hts parameters such as the iron deposition profile, information on the affinity of radionuclides for magnetite and for the outlet end-fittings, feeders and hot leg of the steam generator tubes where the deposits are much thinner, plus various geometric considerations (surface areas, diameters, fluid velocities) via more mechanistic models. some deficiencies in the existing station data were identified during the application of the model to 95zr and 60co. a series of measurements is recommended to obtain the data required to assess the model; in particular: ? develop a good set of deposition constants for all radionuclides of interest (especially 60co, 124sb and 95zr/95nb) including the contributions of dissolved and particulate species. ? develop a good set of purification system removal constants for all radionuclides of interest, including the contributions from dissolved and particulate species ? determine c, the coolant concentration, for all species of interest, including dissolved and particulate species.

Download or read book The Financial Crisis Inquiry Report written by Financial Crisis Inquiry Commission and published by Cosimo, Inc.. This book was released on 2011-05-01 with total page 692 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Financial Crisis Inquiry Report, published by the U.S. Government and the Financial Crisis Inquiry Commission in early 2011, is the official government report on the United States financial collapse and the review of major financial institutions that bankrupted and failed, or would have without help from the government. The commission and the report were implemented after Congress passed an act in 2009 to review and prevent fraudulent activity. The report details, among other things, the periods before, during, and after the crisis, what led up to it, and analyses of subprime mortgage lending, credit expansion and banking policies, the collapse of companies like Fannie Mae and Freddie Mac, and the federal bailouts of Lehman and AIG. It also discusses the aftermath of the fallout and our current state. This report should be of interest to anyone concerned about the financial situation in the U.S. and around the world.THE FINANCIAL CRISIS INQUIRY COMMISSION is an independent, bi-partisan, government-appointed panel of 10 people that was created to "examine the causes, domestic and global, of the current financial and economic crisis in the United States." It was established as part of the Fraud Enforcement and Recovery Act of 2009. The commission consisted of private citizens with expertise in economics and finance, banking, housing, market regulation, and consumer protection. They examined and reported on "the collapse of major financial institutions that failed or would have failed if not for exceptional assistance from the government."News Dissector DANNY SCHECHTER is a journalist, blogger and filmmaker. He has been reporting on economic crises since the 1980's when he was with ABC News. His film In Debt We Trust warned of the economic meltdown in 2006. He has since written three books on the subject including Plunder: Investigating Our Economic Calamity (Cosimo Books, 2008), and The Crime Of Our Time: Why Wall Street Is Not Too Big to Jail (Disinfo Books, 2011), a companion to his latest film Plunder The Crime Of Our Time.

Download or read book Hazard Mitigation Grant Program Desk Reference FEMA 345 written by Federal Emergency Management Agency and published by Createspace Independent Pub. This book was released on 2013-02-01 with total page 236 pages. Available in PDF, EPUB and Kindle. Book excerpt: FEMA's Hazard Mitigation Grant Program is a powerful resource in the combined effort by Federal, State, and local government, as well as private industry and homeowners, to end the cycle of repetitive disaster damage. The Robert T. Stafford Disaster Relief and Emergency Assistance Act was passed on November 23, 1988, amending Public Law 93-288, the Disaster Relief Act of 1974. The Stafford Act included Section 404, which established the Hazard Mitigation Grant Program. In 1993, the Hazard Mitigation and Relocation Act amended Section 404 to increase the amount of HMGP funds available and the cost-share to 75 percent Federal. This amendment also encouraged the use of property acquisition and other non-structural flood mitigation measures. In an effort to streamline HMGP delivery, FEMA encourages States to develop their mitigation programs before disaster strikes. States are adopting a more active HMGP management role. Increased capabilities may include: Conducting comprehensive all-hazard mitigation planning prior to disaster events; Providing applicants technical assistance on sound mitigation techniques and hazard mitigation policy and procedures; Coordinating mitigation programs through interagency teams or councils. Conducting benefit-cost analyses; and Preparing National Environmental Policy Act reviews for FEMA approval. States that integrate the HMGP with their frequently updated State Administrative and Hazard Mitigation Plans will create cohesive and effective approaches to loss reduction. This type of coordinated approach minimizes the distinction between “predisaster” and “post-disaster” time periods, and instead produces an ongoing mitigation effort. Hazard mitigation is any sustained action taken to reduce or eliminate long-term risk to people and property from natural hazards and their effects. A key purpose of the HMGP is to ensure that the opportunity to take critical mitigation measures to protect life and property from future disasters is not lost during the recovery and reconstruction process following a disaster. Program grant funds available under Section 404 of the Stafford Act provide States with the incentive and capability to implement mitigation measures that previously may have been infeasible. The purpose of this Desk Reference is to: Provide comprehensive information about FEMA's Hazard Mitigation Grant Program (HMGP); Increase awareness of the HMGP as an integral part of statewide hazard mitigation efforts; and Encourage deeper commitments and increased responsibilities on the part of all States and communities to reduce damage and losses from natural disasters. This Desk Reference is organized to simplify program information and assist the reader with practical guidance for successful participation in the program. Lists of program-related acronyms and definitions are included, along with appendices that amplify selected aspects of the HMGP. This Desk Reference is organized into 14 sections, each of which presents a major HMGP subject area. In each section, information is presented on the right side of the page. In several sections, job aids containing supplemental material are provided. The job aids for each section can be found at the end of the section. At the front of each section, there is a detailed table of contents to help you locate specific information.

Available in PDF, EPUB and Kindle. Book excerpt: Since the early 1980s, a prominent and consistent conclusion drawn from research on China's defense-industrial complex has been that China's defense-production capabilities are rife with weaknesses and limitations. This study argues for an alternative approach: From the vantage point of 2005, it is time to shift the focus of current research to the gradual improvements in and the future potential of China's defense-industrial complex. The study found that China's defense sectors are designing and producing a wide range of increasingly advanced weapons that, in the short term, are relevant to a possible conflict over Taiwan but also to China's long-term military presence in Asia. Part of a larger RAND Project AIR FORCE study on Chinese military modernization, this study examines the current and future capabilities of China's defense industry. The goals of this study are to 1.

Available in PDF, EPUB and Kindle. Book excerpt: Hydrogen and fuel cells are vital technologies to ensure a secure and CO2-free energy future. Their development will take decades of extensive public and private effort to achieve technology breakthroughs and commercial maturity. Government research programs are indispensable for catalyzing the development process. This report maps the IEA countries' current efforts to research, develop and deploy the interlocking elements that constitute a "hydrogen economy", including CO2 capture and storage when hydrogen is produced out of fossil fuels. It provides an overview of what is being done, and by whom, covering an extensive complexity of national government R & D programs. The survey highlights the potential for exploiting the benefits of the international cooperation. This book draws primarily upon information contributed by IEA governments. In virtually all the IEA countries, important R & D and policy efforts on hydrogen and fuel cells are in place and expanding. Some are fully-integrated, government-funded programs, some are a key element in an overall strategy spread among multiple public and private efforts. The large amount of information provided in this publication reflects the vast array of technologies and logistics required to build the "hydrogen economy."--Publisher description.

Download or read book Global Waves of Debt written by M. Ayhan Kose and published by World Bank Publications. This book was released on 2021-03-03 with total page 403 pages. Available in PDF, EPUB and Kindle. Book excerpt: The global economy has experienced four waves of rapid debt accumulation over the past 50 years. The first three debt waves ended with financial crises in many emerging market and developing economies. During the current wave, which started in 2010, the increase in debt in these economies has already been larger, faster, and broader-based than in the previous three waves. Current low interest rates mitigate some of the risks associated with high debt. However, emerging market and developing economies are also confronted by weak growth prospects, mounting vulnerabilities, and elevated global risks. A menu of policy options is available to reduce the likelihood that the current debt wave will end in crisis and, if crises do take place, will alleviate their impact.
