Field testing of the Cobra Seal System

The Cobra Seal System consists of a passive fiber optic seal and verification equipment which have been modified to take advantage of current technology. The seal permits on-site verification without requiring replacement of the seal. The modifications to the original Cobra Seal System extended the maximum fiber optic cable length from 1 meter to 10 meters. This improvement allowed the Cobra Seal to be considered for application on dry irradiated fuel storage canisters at two Canadian facilities. These canisters are located in an exterior environment exposed to extreme weather conditions. This paper describe the application of the Cobra Seal to these canisters, a housing for the protection of the Cobra Seal body from the environment, and some preliminary results of the IAEA field tests. 4 refs

Chapter 20 Assessment of radiation pollution from nuclear power plants

Nuclear power plants split uranium atoms in a process called fission. In a nuclear power plant, heat is generated to produce steam that spins a turbine to generate electricity. Nuclear energy has been proposed in response to the need for a clean energy source compared to CO2 production plants. However, nuclear energy is not necessarily a source of clean energy as nuclear power plants release small amounts of greenhouse emissions in activities related to building and running the plant. Moreover, even if all safety measures are followed, there is no guarantee that an accident will not occur in a nuclear power plant. In the case of an accident involving a nuclear power plant, the environment and the people around it may be exposed to high levels of radiation. Another important environmental problem related to nuclear energy is the generation of radioactive waste that can remain radioactive and dangerous to human health for thousands of years. There are also several issues with burying the radioactive waste. Here, we describe different types of radioactive waste pollution from nuclear power plants, their environmental effects, nuclear regulations, and nuclear power plant incidents. Moreover, two case studies on nuclear power plant accidents and their consequences are discussed

Proceedings of the international topical seminar on management of ageing of research reactors, Geesthacht/Hamburg, May 8-12, 1995

Die GKSS-Forschungszentrum Geesthacht GmbH und die International Atomic Energy Agency (IAEA) haben vom 8.-12. Mai 1995 in Geesthacht/Hamburg gemeinsam ein internationales Seminar abgehalten zu 'Fragen des Alterns von Forschungsreaktoren'. Mehr als 100 Teilnehmer aus 36 Laendern und 2 internationale Organisationen waren vertreten. In den 52 vorgetragenen Beitraegen wurde die ganze Bandbreite der Einfluesse und Auswirkungen des Alterns diskutiert: Physikalisches Altern, Altern des Konzeptes, Altern der Mitarbeiter und Massnahmen, die alterungsbedingte Effekte und Einfluesse zu identifizieren und entsprechende Gegenmassnahmen zu ergreifen. (orig.)The GKSS Research Centre Geesthacht GmbH and the International Atomic Energy Agency (IAEA) held a joint seminar on 'Management of Ageing of Research Reactors' from May 8-12, 1995, at Geesthacht/Hamburg. More than 100 participants from 36 countries and two international organizations were present. During the seminar 52 papers have been presented discussing the large variety of ageing effects from physical ageing to design ageing and staff ageing and the measures taken to identify and to overcome the ageing effects.
