[en] A summary of the chief activities of the Risoe National Laboratory is given. The material is presented in a revised sequence following upon changes in the organization of the work at Risoe. These changes partly reflect the widened scope of activities, which now include non-nuclear energy research, that resulted from the Act on Energy Policy Measures from April 1976. The sequence is: reactor technology and safety, nuclear fuel cycle, environmental and safety research, materials research, radiation technology, agricultural research, other energy research, research facilities and auxiliary services. For more detailed descriptions of the work in progress, readers are referred to the annual reports of the various departments, and to the two series of research reports as well as to articles appearing in scientific journals. A list of these publications is given. Design data on research facilities are presented. (BP)
