Download or read book Debris Impact on Emergency Coolant Recirculation written by and published by OECD Publishing. This book was released on 2004 with total page 430 pages. Available in PDF, EPUB and Kindle. Book excerpt: Under normal operation, nuclear reactor fuel is cooled by water circulating in the primary circuit. In the case of an accident, the reactor is stopped automatically, and residual fuel heat must be evacuated, typically by use of a safety injection system and a reactor containment spray system. This publication contains the proceedings of a workshop, held in New Mexico, United States in February 2004, to discuss recent research and developments to deal with the impact of debris (such as insulating material, concrete particles or paint) on emergency coolant recirculation systems.

This book was released on 1982 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The postulated failure of high energy piping within a light water reactor containment has raised safety questions related to the generation of insulation debris, the migration of such debris to the containment emergency sump screens and the potential for severe screen blockages. High, or total, screen blockages could result in impairment of the long term RHR recirculation systems. Debris considerations are an integral part of the unresolved Safety Issue A-43, Containment Emergency Sump Performance. This report develops calculational methods and debris transport models which can be used for estimating the quantities of debris that might be generated by a LOCA, the transport of such debris, methods for estimating screen blockages and attendant pressure losses. Five operating plants were analyzed using this debris evaluation methodology. These calculations show the dependency on plant containment layout, sump location and design, and types and quantities of insulation employed. 9 figures, 6 tables.

Download or read book Particle Size Distributions of Debris Upstream and Downstream of the Containment Sump Strainer in a Light Water Reactor written by Matthew Jareb Kappes and published by . This book was released on 2015 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: During a LOCA in a LWR, a containment-sump strainer filters debris, generated from fibrous thermal insulation, from the water collected in the containment sump. The buildup of debris on the strainer and the bypass of debris through the strainer lead to upstream and downstream effects, respectively. The objective of this research was to create a methodology for obtaining PSDs for this debris upstream and downstream of a sump strainer in multiple size ranges. Fibrous debris was injected into an experimental facility which simulated the conditions in a LWR containment sump. Samples were taken downstream of the strainer during the experiment. Using a NanoSight LM10 and two optical microscope systems, size measurements of particles were made. The fractional number of particles between 55-188 nm increased from 0.591 to 0.734 upstream to downstream; the number of all other particle sizes decreased. This trend is consistent with Hutten's [8] statements about the MPPS. For AMIS-1, from upstream to downstream, the fraction of particles smaller than 55 [Lowercase Mu symbol]m increased from 0.77 to 0.89; almost all of the larger particles sizes decreased in number. This demonstrates larger particles being more efficiently filtered. For AMIS-2, from upstream to downstream, the fraction of particles smaller than 340 [Lowercase Mu symbol]m increased from 0.536 to 0.668; all of the larger particle sizes decreased in number. This again demonstrates higher filtration efficiency for larger particles. Different PDFs provided the best fit for the PSDs in each of the size ranges measured. For the nanometer range, the Johnson's S[Subscript B] function provided the best fit. For the 10-500 [Lowercase Mu symbol]m range, the upstream and downstream results were fit best with the log-logistic and lognormal functions, respectively. For the 100-2500 [Lowercase Mu symbol]m size range, the Weibull distribution was found to fit best. Changes in the PDFs fit to the upstream and downstream PSDs were similar to what was found when comparing the upstream and downstream PSD histograms. Size distributions for spherical (tin powder) and angular (SiC F600) particles were easily obtained using the Coulter Counter, however, it didn't provide reliable results for fibrous debris.
