The safety of transport packages may be demonstrated by numerical calculation of load scenarios defined in the IAEA regulations. Possible handling accidents of casks at interim storage sites or in a final repository are typically analyzed by dynamic finite element computations. In each case the investigated load scenario must be transferred into a mathematical model. Secondly the mathematical model must be transferred into a numerical model. Reliable finite element models should be developed by assembling verified sub-models of components. The finite element mesh, material modeling, initial and boundary conditions, contact definitions, and time integration as well as the benefit of pre- and post-calculations are discussed. The paper presents lessons learnt from modeling dynamic test scenarios for finite element analyses over the years.
Full-scale versus small-scale fire testing of fire protection materials for LPG storage vessels
(1992)
This paper presents test results of different fire test series with full-scale fire engulfment (4.85m³ propane vessels protected with an intumescent coating, rock wool or two cementitious fire protection materials based on vermiculite and Portland cement). Furthermore, the correlation of these tests with furnace plate tests and/or numerical calculations are discussed. It is our aim to present a method or way for the usefulness of small-scale fire tests. This method has to be quantified and statistically proved. The paper is a revision and amplification of /13/.
This paper will present test results of different fire test series with full-scale fire engulfment tests (4.85 m³ propane tanks protected with an intumescent coating, rock wool or a heat insulator based on vermiculite and Portland cement). Furthermore, the correlation of these tests with furnace plate tests and/or numerical calculations will be discussed.
