Development of an impact limiter for type B packages-characterization of its polymeric material

Abstract

Impact limiters are sacrificial components widely used to protect radioactive waste packages against damage. In Brazil, a foam developed using the polymer extracted from the castor-oil plant (Ricinus communis) os being studied as a potential impact limiter filling. This paper presents data gathered in an ongoing research program aimed developing a Brazilian Type-B packaging. Foam samples were submitted to study uniaxial static compression, hydrostatic, and impact tests. The results obtained reveal that the castor-oil foam has a mechanical behavior similar to that of regular foams, with good property reproducibility and homogeneity.
