The Second Edition of the Law of Nuclear

“The second edition of The Law of Nuclear Energy represents an outstanding example of both legal research and practice. The author demonstrates a deep knowledge of the legal base and key experiences that apply to counselling in the nuclear sector. Her second edition is certainly interesting for both practitioners looking for comprehensive overview on existing legal framework in this particular field of industry as well as policymakers (from both traditional nuclear states and from nuclear ‘newcomers’) who deal with strategic issues of energy policy and security. The book will also serve as a valuable source of information for international lawyers inquiring into this particular field of law and academicians commenting upon this peculiar area of law.”

“Helen’s book is more than just a textbook. It is well written and comprehensive in coverage and should be read carefully from the outset of policy-making so that governmental context can be as considered as possible. For the developers and financiers, the book provides an important tutorial which should be part of the preparation for early thinking about potential projects. The book is based on wide practical experience of advising on large successful projects around the world, including her ground-breaking experience in her work on the first projects in previously non-nuclear countries where the entire nuclear process has been started from scratch. The book overall is the result of painstaking work and is clearly written and easily assimilable—the author’s passion for her subject shines throughout.”
