During the course of its meetings, the International Expert Group on Nuclear Liability (INLEX) finalized the discussion and review of explanatory texts (including an overview of the IAEA's modernized nuclear liability regime) on the nuclear liability instruments adopted under IAEA auspices in 1997. These texts constitute a comprehensive study of the IAEA’s nuclear liability regime to aid the understanding and to serve as an authoritative interpretation of that regime. In addition to the overview and the explanatory texts, the publication also includes the following documents: a matrix of comparative provisions of the nuclear liability instruments; the text of the "Protocol to Amend the Vienna Convention on Civil Liability for Nuclear Damage"; the consolidated text of the "Vienna Convention on Civil Liability for Nuclear Damage"; and the text of the "Convention on Supplementary Compensation for Nuclear Damage" (the CSC). It is expected that this publication will increase awareness of nuclear liability as an important aspect of nuclear law by becoming a useful tool for legislators, government officials, technical experts, lawyers and nuclear insurers.
