SCKCEN focuses on two crucial questions in waste management “All of the waste, after remaining in- situ for some decades, may, if desired, be regarded as non-radioactive or recycled, with no need for repository disposal.” PPCS report 2004 “Waste containing considerable amounts of Be should not to be acceptable for near-surface disposal. Deep disposal of these waste types should therefore be considered”. Recycling issue BerylliumTritium Total waste volume: 94,645 tonnes 100 years cooling time Will shallow land disposal suffice? Detritiation issue El Cabril Acceptance Criteria: Without detritiation: 16,841 tonnes rejected With detritiation: 675 tonnes rejected
