Download or read book Steam Generators for Nuclear Power Plants written by Jovica Riznic and published by Woodhead Publishing. This book was released on 2017-05-24 with total page 580 pages. Available in PDF, EPUB and Kindle. Book excerpt: Steam Generators for Nuclear Power Plants examines all phases of the lifecycle of nuclear steam generators (NSGs), components which are essential for the efficient and safe operation of light water reactors (LWRs). Coverage spans the design, manufacturing, operation and maintenance, fitness-for-service, and long-term operation of these key reactor parts. Part One opens with a chapter that provides fundamental background on NSG engineering and operational experiences. Following chapters review the different NSG concepts, describe NSG design and manufacturing, and consider the particularities of SGs for VVER reactors. Part Two focuses on NSG operation and maintenance, starting with an overview of the activities required to support reliable and safe operation. The discussion then moves on to tubing vibration, followed by the water and steam cycle chemistry issues relevant to the NSG lifecycle. Finally, a number of chapters focus on the key issue of corrosion in NSGs from different angles. This book serves as a timely resource for professionals involved in all phases of the NSG lifecycle, from design, manufacturing, operation and maintenance, to fitness-for-service and long-term operation. It is also intended as a valuable resource for students and researchers interested in a range of topics relating to NSG lifecycle management. - Fulfills the need for a detailed reference on steam generators for nuclear power plants - Contains comprehensive coverage of all phases of the nuclear steam generator lifecycle, from design, manufacturing, operation and maintenance, to fitness-for-service and long-term operation in one convenient volume - Presents contributions from key manufacturers and research institutes and universities

This book was released on 2012-12-06 with total page 828 pages. Available in PDF, EPUB and Kindle. Book excerpt: Different physical models for the Snoek-type relaxation in ternary systems (Fe-C-Me) are analyzed from the viewpoint of a distance of interatomic interaction taken into account: For non-saturated from the viewpoint of overlapping of interatomic interaction in b.c.c. alloys the physically sufficient and optimal for the computer simulation is the short-range model, which takes into account the interatomic interaction and the average amount of substitutional atoms in the first coordination shell, only. For high alloyed b.c.c. systems (i.e. with the overlapped interatomic interaction) the carbon atom undergoes an interaction of a few substitutional atoms simultaneously. That leads to the appearance of one broadened Snoek peak. Activation energy of such a peak is summed from the "elastic" and "chemical" interatomic interactions. Experimental results for alloys with b.c.c. solid solution structure and its computer simulations allow to introduce the new criterion for the high alloy state of monophase steels: the high alloyed state corresponds to the situation when substitutional atoms can not be considered any longer as the isolated atoms. From the viewpoint of mechanical spectroscopy this situation corresponds to the appearance of one broadened IF Snoek-type peak instead of two peaks existed for the steels with lower substitutional atom concentration.

This book was released on 1993 with total page 26 pages. Available in PDF, EPUB and Kindle. Book excerpt: Some CANDU nuclear generating stations have considerable amounts of hard sludge deposits in the steam generators which are beginning to affect their performance both directly through interfering with the steam/water flow and with heat transfer, and indirectly by providing sites for cracking, intergranular attack, crevice corrosion, and/or pitting of tube and support structures under the adherent deposits. This report present results of a study on the effect of chemical reactions between sludge components on the consolidation of sludge.

Download or read book Thermal Hydraulics of Steam Generator Sludge written by and published by . This book was released on 1991 with total page 23 pages. Available in PDF, EPUB and Kindle. Book excerpt: The sludge deposits on top of the tubesheet in commercial steam generators create regions of high susceptibility to tube corrosion. It is believed that the corrosion occurs when the sludge deposit becomes too deep for the liquid to penetrate freely. This leads to liquid deficient regions with high chemical concentrations on the tube surface. A one-dimensional model of two-phase flow in porous media has been developed. The model considers a slab of porous medium on a horizontal non-porous surface, both under water. Heat is transferred from a vertical surface. The vapor, which is generated, flows vertically upward and the liquid is replenished by a counterflow. Under steady state conditions the mass flow rate of liquid equals that of vapor at every point along the flow path. The solution requires a minimum of five equations; continuity and momentum for the liquid and the vapor phases and energy. The momentum equations are extensions of the Darcy equation to the inertial flow regime in porous media. All five equations can be described as first order differential equations. They can be integrated with respect to distance into the sludge pile using the appropriate boundary conditions at the top of the porous slab and the transition point to ''dryout'' or at the bottom of the slab whichever comes first. The conservation of chemical species can be easily incorporated into the above system of equations. A FORTRAN computer program was developed to solve the above set of equations. The solution yields the distribution of the liquid and the vapor velocities and pressures, the heat flux, the liquid saturation and the chemical concentration.

Download or read book Integration of a Sludge Deposition Model Into the ATHOS3 Computer Program and Application to a Sample U tube Steam Generator written by and published by . This book was released on 1993 with total page 10 pages. Available in PDF, EPUB and Kindle. Book excerpt: This study pursues a approach to sludge deposition prediction, similar to that published by Keefer, et al. Starting with the same basic model as Beal and Chen, Keefer, et al. made several simplifying assumptions so that a closed form solution to the equations describing deposition and reentrainment could be obtained. Using a similar approach, this study shows how the physics of the sludge model can be integrated directly into a steady-state thermal-hydraulic analysis computer program such as ATHOS3 to provide an estimate of the relative amounts of sludge expected to accumulate in various regions of a steam generator. This allows sludge deposition and reentrainment rates (i.e. rate coefficients) to be calculated at every node used to model the steam generator (which can be many thousands), so that sludge deposition patterns can readily be examined along with thermal-hydraulic parameters.
