Abstract:
The pre-disposal management of Radioactive Liquid Organic Waste (RLOW) is hampered by its challenging
physico-chemical properties. In this work, a straightforward conditioning option based on RLOW impregnation
on absorbing materials and followed by encapsulation in a stable geopolymeric matrix is proposed, avoiding
onerous pre-treatments and the use of surfactants. Recycled materials have been investigated as adsorbent and
geopolymer precursors to foster process sustainability. Relevant properties have been studied to ascertain the
waste acceptance criteria accomplishment: materials compatibility, RLOW loading factor and bleeding, micro-
structure, compressive strength, leaching and thermal stability. This approach is promising, although some
criticalities remain unsolved
