The National Bureau of Standards Reactor was built not only to serve the needs of the NBS but also those of the greater Washington Scientific Community and other government agencies. The Reactor Radiation Division was established to operate the reactor and to foster its scientific and technological use. Toward this end, the Division has a small nucleus of scientists experienced in the use of reactors for a wide range of scientific and technical problems. In addition to pursuing their own research and developing sophisticated experimental facilities, they actively seek out and encourage collaboration with other scientists, engaged in challenging programs, whose work can benefit from use of the reactor, but who as yet do not have the reactor experience necessary to take full advantage of the The Division also provides irradiation services to a wide variety facilities available. of users as well as engineering and other technical services. The reactor operates at 10 Mw and is designed to provide a broad spectrum of facilities ranging from intense neutron beams to extensive irradiation facilities, making it one of the most versatile high flux Research Reactors in the country. Thus it is able to serve a large number of scientists and engineers in a broad range of activities both within and outside the NBS. Use of the reactor by individuals and organizations outside the Reactor Radiation Division has continued at a high level during the past year. Thirty-three scientists from other parts of the Bureau, representing 20 man-years of effort, use the reactor regularly either directly or in cooperation with scientists in the Division. An additional 80 scientists, engineers, and technicians from other agencies, universities and industry spent 34 man-years of effort using the reactor during the past year. The purpose of this report is to summarize the activities of the large number of users outside the Division as well as the work in the Division. The summaries are divided into two groups. activities. One is the research activities and the other is the operation and service The research activities are further broken down into three groups: the first includes all the work of the Division and most of the collaborative work; the second describes the activities of our formal interagency collaboration based on long-term arrangements where scientists from other agencies are actually stationed at the reactor; and the third catagory is the summary of activities of other NBS divisions which use the reactor directly rather than through collaboration with Reactor Radiation Division scientists.
