An assessment of loss-of-containment potential because of knuckle buckling for 4:1 steel containment heads
Description
4:1 diameter-to-height rise ratio torispherical nuclear steel containment head geometries were investigated experimentally and analytically for effects of knuckle buckling from internal pressure. The particular focus of the program was to assess the loss-of-containment potential. So the experiments were carried to rupture when feasible. Results of both small-scale tests and two large-scale (1/8) tests are reported. Significant ratios of knuckle buckling to design pressures were found (1.6 to 2.4). In addition, very large rupture pressure to design pressure ratios (7 to 7.5) indicate adequate reserve margin for loss-of-containment for these geometries and materials. A copy of the contractor's final report is included
