Available in PDF, EPUB and Kindle. Book excerpt: The objective of this thesis was to develop a mechanistic model to simulate iodine behaviour within the containment structure of a nuclear generating station. The model included both aqueous and gas phase radiolysis and interfacial mass transfer. Validation of the model was conducted for each phase separately and the combined model was applied to a few reactor accident scenarios. The aqueous model successfully reflected various experimental data over a wide range in pH, iodide concentration, temperature, and dose rate. The incorporation of gas phase chemistry served to determine the dominant chemical forms of gaseous iodine. In addition, it was observed that hydrogen, likely to be present in the containment atmosphere, would hinder the elimination of molecular iodine. Finally, the interaction of iodine with nitrogen oxides was significant when compared to reactions with ozone. Hence, the deposition of ozone onto surfaces did not impact iodine behaviour. The development of this model will serve as a useful tool for reactor safety assessments.

This book was released on 1999 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The impact of organic compounds on iodine behaviour was investigated under a range of post-accident chemical conditions expected in a reactor containment structure. A bench scale apparatus installed in the irradiation chamber of a Gammacell was used to provide continuous measurement of iodine volatilization rates from 10-6 to 10 -4 CsI solutions with pH values from 5 to 9. The rate of production of volatile iodine was evaluated in the presence of 10-3 M concentrations of various alkyl halides, carbonyls, and aromatics; the three classes of organic compounds most likely present in containment. Iodo-organics and molecular iodine in the gas and liquid phases of the irradiated samples were analyzed using gas chromatography, mass spectrometry, and UV spectrophotometry. A model was developed that simulates the radiation chemistry of iodine in the presence of organic compounds and evaluated against the experimental results. The results indicated that organic compounds can be classified into groups, based on their distinct effects on iodine behaviour. Iodine volatilization increased significantly, up to two orders of magnitude, in the presence of carbonyls and alkyl chlorides, while it decreased in the presence of aromatics. Gas and liquid phase analysis indicated that chloro-iodo organics and alkyl iodides are the major types of volatile iodo-organics formed in the presence of alkyl chlorides and carbonyls, respectively, while no volatile iodo-organics are formed in the presence of aromatics. Molecular iodine measurements in the systems showed that I2 concentration increases in the presence of alkyl chlorides and decreases in the presence of carbonyls and aromatics. The kinetic-based model, containing a mechanistic description of iodine chemistry and generic semi-mechanistic reactions for various classes of organics, provided a reasonable prediction of the experimental results. The majority of the model and experimental results were in agreement within an order of magnitude. The results of this research will assist in predicting and reducing the radiological consequences of reactor accidents. In particular, the results indicate the advantage of maintaining basic pH and avoiding alkyl halide or ketone based solutions in post-accident reactor containment, in order to reduce radioactive iodine volatility, and hence, improve reactor safety.

Available in PDF, EPUB and Kindle. Book excerpt: The Three Mile Island and Chernobyl nuclear incidents emphasized the need for the world-wide nuclear community to cooperate further and exchange the results of research in this field in the most open and effective manner. Recognizing the roles of heat and mass transfer in all aspects of fission-product behavior in sever reactor accidents, the Executive Committee of the International Centre for Heat and Mass Transfer organized a Seminar on Fission Product Transport Processes in Reactor Accidents. This book contains the eleven of the lectures and all the papers presented at the seminar along with four invited papers that were not presented and a summary of the closing session.

Available in PDF, EPUB and Kindle. Book excerpt: Written by sixteen of Canada's pioneering nuclear scientists, the book focuses on Canada's nuclear program at AECL's laboratories at Chalk River, Ontario, and Whiteshell, Manitoba, between the years 1943 and 1985. Topics include the organization and operations of AECL's laboratories, nuclear safety and radiation protection, radioisotopes, basic research, development of the CANDU reactor, and the management of radioactive wastes. As well as providing a valuable historical perspective on Canadian science, Canada Enters the Nuclear Age offers useful guidance for innovative scientific development in the future, a future that will depend on developing and nurturing technically sophisticated industry.
