I. SHUMKOV State Committee for Defense Industry (Goseomoboronprom) Moscow, Russia 1. General Description of the Problem Undoubtedly, the problem of nuclear submarine decommissioning and recycling has been worrying Russian civil and military specialists involved in development, building and operation of submarines for many years.

A great number of nuclear submarines are due to be decommissioned before 2000. The political decisions surrounding the disposal of nuclear compartments, radioactive wastes and spent fuel differ appreciably between the countries that own the boats. The decision makers involved thus need help in comparing and assessing alternative options for the decommissioning of their nuclear submarine fleets. The present volume offers such assistance, with its discussions of the risks associated with long-term water storage of the boats, radioactive and chemical contamination, spent fuel and waste management, and handling and recycling reactor compartments.

With the end of the Cold War, Russia's submarines were no longer needed to deter or fight Western navies and were very expensive to operate and maintain. Older submarines were taken out of service in large numbers, but without firm plans and infrastructure in place to remove and adequately care for their nuclear components, problems soon developed over the disposition of spent fuel assemblies. Problems arose also of course between Russia and the international community as to the best way to respond to the challenge. This book looks at those problems, first discussing Russia's economy, its environment, and the Russian Navy, and then covering in detail the spent fuel of Russian submarines and related nuclear problems. The engagement of the international community on the issue is then addressed. A theoretical analysis is offered on how Russia's fellow nations can help remedy a troubling environmental problem in a difficult country.

Following the acquisition of the atomic bomb by five states, the United Nations began drafting several treaties to limit nuclear proliferation. These efforts failed, as four more states also acquired nuclear weapons. In a similar vein, an attempt to limit atomic weapons - primarily within the two superpowers - was initiated. While the number of weapons has decreased, the new bombs now being manufactured are more powerful and more precise, negating any reduction in numbers. In the field of civil nuclear use, all nuclear facilities (reactors, factories, etc.) have a limited lifespan. Once a plant is permanently shut down, these facilities must be decommissioned and dismantled. These operations are difficult, time-consuming and costly. In addition, decommissioning generates large volumes of radioactive waste of various categories, including long-lived and high-activity waste. Risks to the environment and to health are not negligible during decommissioning. The International Atomic Energy Agency (IAEA) and the Nuclear Energy Agency (NEA) of the Organisation for Economic Co-operation and Development (OECD) have produced numerous publications with recommendations. Each state has its own decommissioning strategy (immediate or delayed) and final plan for the site - whether it be returning it to greenfield status or obtaining a nuclear site license with centuries-long monitoring.

Umbilical cord blood, previously discarded, has emerged as a new source of stem cells for hematologic reconstitution, bone marrow failures and other hematologic deficiencies. It has become increasingly clear that umbilical cord tissue contains unique stem cells of great potential for regenerative medicine. Importantly, umbilical cord blood is abundant, can be banked and transported with ease, and thus has an indisputable potential for future regenerative therapies. Driven by a massive interest for regenerative medicine and ethically acceptable stem cell sources, the scientific literature on umbilical cord stem cells has exploded.This book provides a consolidated overview of basic, translational as well as clinical research in academic institutions and industry, on hematopoietic and mesenchymal stem cells contained within umbilical cord tissue, as well as other more recently discovered stem and precursor cells of not yet fully elucidated potential. Although not discussed here, umbilical cord cells have been successfully reprogrammed into pluripotent stem cells (iPS), opening the door for a vast array of applications with this abundant human material likely catapulting cord-derived stem cells to the forefront of cell-based regenerative medicine.Suitable as a primer and reference book for medical fellows and researchers, this book can also be used by students (undergraduate and graduate) as a starting point into the vast literature on stem cells and their potential.

Until the late 1970s, most commercial power plant operators outside the United States adopted a spent fuel management policy of immediate reprocessing and recycling of recovered products. In response to rising reprocessing prices, decreasing values of re covered products, concerns over proliferation risks, and a belief in the favorable eco nomics of direct disposal, many utilities have since opted to store spent fuel on an in terim basis pending the availability of direct disposal facilities or a change in the eco nomic and/or political climate for reprocessing and recycling uranium and plutonium. Spent fuel has traditionally been stored in water-filled pools located in the reactor building or fuel handling buildings, on reactor sites, or as part of large centralized fa cilities (e.g. Sellafield, La Hague, CLAB). Because the economics of pool storage are dependent on the size of the facility, the construction of additional separate pools on reactor sites has only been pursued in a few countries, such as Finland and Bulgaria.

The Russian NATO Advanced Research Workshop on "Scientific Problems and Unresolved Issues Remaining in the Decommissioning of Nuclear Powered Vessels and in the Environmental Remediation ofTheir Supporting Infrastructure," was held in Moscow, Russia at the Presidium of the Russian Academy of Sciences on April 22-24, 2002. This was the third in this series of North Atlantic Treaty Organization (NATO) sponsored workshops in Moscow on nuclear vessel decommissioning. The first one was in June 1995 and served to focus international attention on the problems of nuclear vessel decommissioning in Russia and elsewhere. The second one was in November 1997 and it focused on the risks associated with nuclear vessel decommissioning. Attendance at the current workshop was approximately 100 with participants form Russia, United States, Norway, France, Denmark, Germany, Japan, Korea, NATO, and the European Union. The Workshop was sponsored and funded by the Security-Related Civil Science and Technology Program of the Scientific and Environmental Affairs Division ofNATO. Within Russia, the Workshop was sponsored and supported by the Russian Academy of Sciences, Minatom of Russia, Rossudostroenie, Ministry of Industry and Science of Russia, and the Russian Navy. Within the U.S., the Workshop was supported by the U.S. Department of Energy. The sponsorship and support of all of the above organizations are gratefully acknowledged.

A study of the legacy of nuclear contamination in the Soviet Union. It gives the location and characteristics of the accumulated radioactive material and wastes by each sector, from ore and mining to use and disposal. It describes types of storage, capacity and utilization, age and location. It gives information on the territories and locations contaminated, by normal operations and by accidents, from which strategic plans for remediation can be formulated.

The end ofthe Cold War opened unprecedented opportunities for reductions in weapons of mass destruction. With these opportunities came new challenges, both scientific and political. Traditionally approached by different groups, the scientific, technical and political challenges are inextricably intertwined. Agreements to dismantle and destroy chemical, nuclear and conventional weapons, after having been negotiated via diplomatic channels, require the expertise of scientists associated with their development to determine the safest and most environmentally sound methods of destruction. It is in this context that representatives from sixteen countries and five international organizations were convened jointly by NATO, the Ministry of Foreign Affairs of the Federal Republic of Germany and the State Government of North Rhine Westphalia 19-21 May, 1996 in a meeting near Bonn to take stock of worldwide efforts to destroy and dismantle chemical, nuclear and conventional weapons remaining after the end ofthe Cold War. NATO support was provided under the auspices of the NATO Science Committee's Panel on Disarmament Technologies. The conference brought together the major actors involved in the dismantlement and destruction of chemical, nuclear and conventional weapons, highlighted the substantial accomplishments achieved in this area and pinpointed the remaining technical obstacles still to be overcome. It also underlined the critical importance of transparency, data exchange and verification as indispensable preconditions for disarmament and cooperative security.
