Advanced LOCA code uncertainty assessment: preliminary calculations for a Westinghouse 4 loop PWR

Abstract

Three large break LOCA calculations for Sizewell B using TRAC-PF1/MOD1 have been performed. They are: base case, post-dryout heat transfer x 0.5, and condensation Stanton number x 0.1. The base case and reduced heat transfer case were compared with other similar calculations. The results were consistent, differences being accounted for qualitatively. The three cases were compared with one another. The resulting peak clad temperatures were: base case 963K; post-dryout heat transfer x 0.5 1113K; condensation Stanton number x 0.1 1003K. (author).
