This conference proceedings examines the most recent research and developments related to the impact of debris on emergency coolant recirculation.  Held in Albuquerque, New Mexico in February 2004, this proceedings had sessions on safety assessment and regulatory requirements, experimental work, analytical work, and industry solutions.  The proceedings present the papers presented as well as a summary of discussions that took place.





LOCA Induced Debris Characteristics for Use in ECCS Sump Screen Debris Bed Pressure Drop Calculations

Nuclear Energy Agency

Pressure drop calculations across a LOCA induced fibrous debris bed have been successfully demonstrated to be accurate using the NUREG/CR-6224 semi-theoretical head loss correlation. One of the critical parameters needed for the NURE/CR-6224 correlation to predict the pressure drop across a fibrous debris bed are the characteristics of the debris constituents (density and characteristic size). This paper provides a brief description of the NUREG/CR-6224 head loss correlation and presents suggested debris characteristics of typical sources of debris found in American nuclear power plants...
