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.

Book Synopsis Nuclear Safety in Light Water Reactors by : SARNET
Download or read book Nuclear Safety in Light Water Reactors written by SARNET and published by Academic Press. This book was released on 2011-12-05 with total page 731 pages. Available in PDF, EPUB and Kindle. Book excerpt: This vital reference is the only one-stop resource on how to assess, prevent, and manage severe nuclear accidents in the light water reactors (LWRs) that pose the most risk to the public. LWRs are the predominant nuclear reactor in use around the world today, and they will continue to be the most frequently utilized in the near future. Therefore, accurate determination of the safety issues associated with such reactors is central to a consideration of the risks and benefits of nuclear power. This book emphasizes the prevention and management of severe accidents to teach nuclear professionals how to mitigate potential risks to the public to the maximum extent possible. - Organizes and presents all the latest thought on LWR nuclear safety in one consolidated volume, provided by the top experts in the field, ensuring high-quality, credible and easily accessible information - Explains how developments in the field of LWR severe accidents have provided more accurate determinations of risk, thereby shedding new light on the debates surrounding nuclear power safety, particularly in light of the recent tragedy in Japan - Concentrates on prevention and management of accidents, developing methodologies to estimate the consequences and associated risks

Available in PDF, EPUB and Kindle. Book excerpt: The ultimate aim of a description of iodine behavior in severe LWR accidents is a time-dependent accounting of iodine species released into containment and to the environment. Factors involved in the behavior of iodine can be conveniently divided into four general categories: (1) initial release into containment, (2) interaction of iodine species in containment not directly involving water pools, (3) interaction of iodine species in, or with, water pools, and (4) interaction with special systems such as ice condensers or gas treatment systems. To fill the large gaps in knowledge and to provide a means for assaying the iodine source term, this program has proceeded along two paths: (1) Experimental studies of the chemical behavior of iodine under containment conditions. (2) Development of TRENDS (Transport and Retention of Nuclides in Dominant Sequences), a computer code for modeling the behavior of iodine in containment and its release from containment. The main body of this report consists of a description of TRENDS. These two parts to the program are complementary in that models within TRENDS use data that were produced in the experimental program; therefore, these models are supported by experimental evidence that was obtained under conditions expected in severe accidents. 7 refs., 1 fig., 2 tabs.

Book Synopsis The Impact of Organic Compounds on Iodine Behaviour Under Conditions Relating to Nuclear Reactor Accidents by : Fariborz Taghipour

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.

Book Synopsis Iodine Chemical Forms in LWR Severe Accidents by :
Download or read book Iodine Chemical Forms in LWR Severe Accidents written by and published by . This book was released on 1991 with total page 17 pages. Available in PDF, EPUB and Kindle. Book excerpt: Calculated data from seven severe accident sequences in light water reactor plants were used to assess the chemical forms of iodine in containment. In most of the calculations for the seven sequences, iodine entering containment from the reactor coolant system was almost entirely in the form of CsI with very small contributions of I or HI. The largest fraction of iodine in forms other than CsI was a total of 3.2% as I plus HI. Within the containment, the CsI will deposit onto walls and other surfaces, as well as in water pools, largely in the form of iodide (I−). The radiation-induced conversion of I− in water pools into I2 is strongly dependent on pH. In systems where the pH was controlled above 7, little additional elemental iodine would be produced in the containment atmosphere. When the pH falls below 7, it may be assumed that it is not being controlled and large fractions of iodine as I2 within the containment atmosphere may be produced. 17 refs., 5 tabs.
