Off-gas capture: Securing a blue-sky future

摘要

AFCP's off-gas capture project involves a holistic approach to the removal and disposal of radionuclides from potential future fuel recycling activities. The project focuses on understanding gas generation, together with options for their capture and appropriate materials for their storage and disposal. Focusing on I-129, AFCP's off-gas project is looking at novel methods and world-leading chemistry for the removal of I-129 from future waste streams. This involves moving from a 'dilute and disperse' to a 'contain and confine' strategy via the development of suitable absorbents for extraction and wasteforms for disposal. But how is this actually achieved in off-gas work? In real terms, this switch to a 'contain and confine' strategy requires liaison between the teams developing iodine removal methods and those involved in wasteform generation in order to optimise both processes simultaneously.
