title: Erratum.
abstract: In Eliot Marshall's article "End game for the N Reactor?" (News & Comment, 2 Jan., p. 17), the environmental group demanding an impact statement on the plant's restart is the Natural Resources Defense Council. The present manager of the N Reactor is UNC Nuclear Industries, Inc., not Rockwell International, which runs the PUREX plant at the same site. Both companies will be replaced by Westinghouse this year.
