Development of multi-walled SFPIC high-integrity containers

Two containers, 200 liters and 400 liters, made from polymer impregnated concretes have been successfully developed for disposal of low- and intermediate-level radioactive wastes in both deep sea and underground environments. The container design is one of an outer steel shell which is only considered for predisposal conditions. The inner liner is manufactured from a proprietary steel fiber-reinforced polymer impregnated concrete which exhibits excellent properties of strength, elasticity, resistance to chemical, fire, radiation, and bacterial attack, and low permeability. The temperature characteristics of the design allow a wide variety of waste stream compatability with virtually no pretreatment. The inherent cost/performance of concrete provides the user with an economical means of disposing of certain radwastes streams irrespective of burial site or depth
