[en] WRENDA 81/82 is the seventh edition of the World Request List for Nuclear Data. This list is produced from a computer file of nuclear data requests, maintained by the Nuclear Data Section of the International Atomic Energy Agency (IAEA). The requests are provided by official bodies, such as national nuclear data committees, through four regional data centers serving all Member States of the IAEA. Each request included indicates: that the estimated accuracy of the nuclear data available does not satisfy the requirements encountered; and that, consequently, new data measurements and/or data evaluations with improved accuracy are highly desirable. WRENDA is intended to serve as a guide to experimentalists, evaluators and administrators when planning nuclear data measurement and evaluation programs. The requests in this edition come from 15 different countries and one international organization. (author)
