DEFORMATION ANALYSIS ON A CONTAINMENT VESSEL OF A NUCLEAR SHIP IN CASE OF MARINE CASUALTIES

Deformations of a containment vessel in the case of marine casualties such as collision, grounding and sinking are analysed using the finite element method. The results obtained are used to evaluate the allowable displacement and load with the aid of the ASME Code for the safety of a containment vessel. Conclusions are: (1) Values of less than 40-60 mm are permissible for the displacement caused to the containment vessel by a longitudinal bulkhead in case of collision. (2) Values of less than 0.01-0.02 rad are permissible for the inclination of the inner bottom plate deformed in a conical shape in case of grounding. (3) The permissible value is less than 1MPa for external pressure in case of sinking.
