Treatment of stored radioactive liquid organic waste at NECSA prior to disposal

Liquid radioactive waste containing small quantities of organic compounds are stored in high density polyethylene (HDPE) drums at the South Africa Nuclear Energy Corporation (Necsa). These wastes were not encapsulated into cement like other waste streams due to the possibility that the organic co...
