Test of 6-in. -thick pressure vessels. Series 3: intermediate test vessel V-7B. [BWR; PWR]
Intermediate test vessel V-7 was repaired a second time and retested hydrostatically as vessel V-7B. The flaw for this test had the same geometry as that for the first two tests, that is, a sharp outside surface flaw 547 mm long by about 135 mm deep in the 152-mm-thick test cylinder. The V-7B flaw was situated in the heat-affected zone of a half-bead weld repair made according to Section XI of the ASME Boiler and Pressure Vessel Code. The vessel failed as expected by ligament rupture at a pressure of 152 MPa, which is slightly higher than that observed in the two previous tests. The rupture pressure was sustained for a short time, during which the flaw continued to tear slowly. The test demonstrated that the flaw in the weld repair region was as stable as those in the original base metal at the test pressures. The test also demonstrated that the repaired and flawed vessel was capable of carryng more than twice the design load without failure. Pretest analyses and test data are included.
