Instructions for obtaining NUREG/CR-6224 Correlation Software |
Instructions for obtaining "NUREG/CR-6224 Correlation and Deaeration Software Package" from the NRC Public Document Room. The software package has been developed for NRC staff to perform confirmatory analysis in computing head loss and air bubble generation across debris-covered PWR sump screens. If licensees desire to use it for design purposes, the software package needs to be independently qualified and verified in accordance with NRC quality assurance requirements. |
