Abstract
The objective of this report was to attempt to justify the leak-before-break concept in reactor safety analyses, thus eliminating the need to show protection against the double-ended guillotine break in these analyses. The two assumptions of the concept: (1) A complete break would not occur, and (2) A leak via a through crack would be discovered before the crack size approached the critical value were discussed and conditions to insure validity of each assumption were outlined. Methods of analyses in various countries were also discussed. It was noted that the determination of the area of elastoplastic opening of a crack for a prescribed flow rate is a difficult problem, and it was recommended that testing be performed on full size pipes under postulated conditions.
