Integration of a sludge deposition model into the ATHOS3 computer program and application to a sample Utube steam generator
Abstract
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 steadystate thermalhydraulic 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 thermalhydraulic parameters.

The development of remedial measures of shot peening have given nuclear utilities viable measures to address primary water stress corrosion cracking to extend steam generator life. The nuclear utility industry is now faced with potential replacement of steam generators in nuclear power plants due to stress corrosion cracking and intergranular attach in crevice locations on the secondary side of steam generators at tube support plates and at the crevice at the top of the tube sheet. Significant work has been done on developing and understanding of the effects of sludge buildup on the corrosion process at these locations. This sessionmore »

ATHOS3 code analysis of tube plugging effects on the thermalhydraulic characteristics of a oncethrough steam generator
The effects of tube plugging on local and global thermalhydraulic parameters are analyzed for a fullscale oncethrough steam generator (ThreeMile Island Unit 1A). A threedimensional analysis has been performed, by considering all pertinent geometric details, including the presence of an open tubefree lane in the generator. Three test cases have been analyzed by using the ATHOS3 computer code. First, a normal unit is simulated, and then the same unit with about 8% plugged tubes is simulated by using the same computational grid. Finally, the pluggedtube case is analyzed with a finer grid. In all calculations, the algebraicslip flow model, basedmore » 
Dynamic stability experimental/analytical program results on a multiple tube sodium heated steam generator model employing double wall tubes
Experimental results are described of a test program which induce water/steam dynamic instability in the multiple tube circuits of a sodium heated, doublewall tube, steam generator model whose water/steam side is designed to operate under oncethrough conditions with exit superheat (457/sup 0/C/855/sup 0/; 15.8 MPa/2290 psia). The instability thresholds were determined experimentally with offnominal operation in order to establish the stability margin that exists with and without the damping orifice configuration employed at the inlet of each tube circuit. Two classes of experiments were performed; one with low magnitudes of water/steam mass velocity resulting in high exit superheat (Benson Cycle),more »
