Single Rod Heat Transfer Tests to Study the Effects of Crud Deposition
Volume 2: Thermal Hydraulics, 2006Researchers have performed many studies to try to understand crud formation on the fuel pin clad surfaces, which has been observed in pressurized water reactors (PWR) as a result of sub-cooled nucleate boiling and precipitation reactions. Crud deposits, may cause an unexpected change in core power distribution known as crud induced power shift (CIPS ...

10th International Conference on Nuclear Engineering, Volume 4, 2002
Many studies have been undertaken to understand crud formation on the upper spans of fuel pin clad surfaces, which is called axial offset anomaly (AOA), is observed in pressurized water reactors (PWR) as a result of sub-cooled nucleate boiling. Separately, researchers have considered the effect of water radiolysis in the primary coolant of PWR.

Analyses of crud deposits on fuel rods in PWRs using Mössbauer spectroscopy
Journal of Nuclear Materials, 2010Abstract To assess the influence of boron iron compounds deposited on fuel rods on unexpected power shifts in pressurized water reactors, samples of crud scrapes retrieved during refuelling from three reactor cores were analyzed using 57 Fe Mossbauer spectroscopy.

Study on Thermal Conductivity Model for Porous PWR CRUD Depositions
Volume 11: Student Paper CompetitionAbstract In this study, corrosion product deposition test is carried out to measure effective thermal conductivity of CRUD depositions. Effective thermal conductivity is found to be a function of heat flux with an average value of 1.3866 W/(m × K).

Model of the Deposition of Colloidal Crud Particles on the Fuel Elements of Nuclear Power Plants
Nuclear Science and Engineering, 1983Experimental data on the adhesion of ..cap alpha..-Fe/sub 2/O/sub 3/ on large ZrO/sub 2/ pellets are presented and discussed in terms of the colloidal interactions of the two double layers. The pH dependence of adhesion is thus explained. The relevance of colloidal interactions of this type in reactor conditions is then discussed, through the ...

Nuclear Technology, 1991
This paper discusses the relative importance of the soluble and particle fractions that take part in the transport of pressurized water reactor corrosion produce in terms of modeling research. A model is proposed that considers the dominant role of the colloidal/particle fraction in the primary coolant system mass and radioactivity transfer.
