Very pleased to be engaged by IAEA to lead an independent peer review of proposals from the Ghana Atomic Energy Commission (GAEC) to dispose of disused sealed radioactive sources in a purpose-designed borehole. The peer review team comprised myself and three other international experts. During the course of the mission we reviewed the GAEC borehole safety case, safety assessments for operations and post-closure and geological investigation work undertaken to characterise the proposed disposal site. The review concluded with a week-long meeting at the Vienna headquarters of the IAEA where we discussed and presented our findings to IAEA and GAEC representatives.
