摘要: The Ford Nuclear Reactor (FNR) at the University of Michigan (UM) was a light-water cooled and moderated open-pool design reactor (UM 2012). It had a heterogeneous core composed of aluminum and enriched uranium-235 (UM 2006). The FNR went critical in 1957 and provided neutron and gamma irradiation services, neutron beam port experimental facilities, and training facilities for use by faculty, students, and researchers from UM, other universities, and industrial organizations. The FNR was operated by the Michigan Memorial Phoenix Project of UM under U.S. Nuclear Regulatory Commission (NRC) License R-28, Docket 50-2, until it was shut down in July 2003. The fuel was removed in December 2003. CH2M HILL conducted the historical site assessment in 2003 to assess and detail the radiological status of the FNR. Results of radiological surveys showed that many potentially impacted areas were free of contamination, including a major portion of the FNR structure. However, non-routine occurrences, accidents, or spills between 1959 and 2001 contributed to the contamination of several systems and surfaces associated with the reactor (UM 2006).
