The Ames Laboratory Research Reactor (ALRR) was designed in 1960-1961 and constructed in 1961-1965. It achieved criticality on February 17, 1965 and full power on July 12, 1965. Full time operation at its full power of 5 Megawatts was begun in June 1966 and continued through December 1977, producing a total of 15,200 Megawatt days of thermal energy. The decision to shut down the reactor at the end of 1977 was made in the summer of 1977. Planning and document preparation for decommissioning began at that time. The goal of removing all reactor-related radioactivity coupled with the realization that the building constitutes a valuable asset led DOE to select Removal of the Reactor Pedestal as the degree of decommissioning to be undertaken and budgeted. In planning, the work was divided into the following four phases and each of these into a number of tasks: (1) placing the reactor in stand-by status; (2) disposal of removable parts; (3) deactivation; and (4) removal of reactor pedestal. This report gives a detailed account of this operation with photos taken at various stages of the operation.
