2 Brief History of MURR February 3, 1959 University of Missouri President Elmer Ellis announces the University will construct a research reactor. November 21, 1961 Construction Permit No. CPRR-68 is issued to The Curators of the University of Missouri by the US Atomic Energy Commission authorizing the University to construct a 10 MW research reactor. July 16, 1963 Initial on-site construction begins. October 11, 1966 Facility License No. R-103 is issued authorizing the University to operate the 10 MW research reactor at steady-state power levels up to a maximum of 5 MW. October 13, 1966 The reactor establishes initial criticality with a 5.2 Kg uranium aluminum alloy core. June 30, 1967 The reactor operates at 5 MW for the first time.

3 Brief History of MURR (con t) July 14, 1969 August 13, 1971 July 9, 1974 July 18, 1974 September 1, 1977 August 31, 2006 The reactor starts a 5 MW, 100-hour-per-week operating schedule. Use of the 6.2 Kg uranium aluminide dispersion UAl x fuel core begins. The US Atomic Energy Commission issues Amendment No. 2 to No. R-103 authorizing the University to operate the reactor at steady-state power levels up to a maximum of 10 MW. The reactor is upgraded to 10 MW. The reactor starts a 10 MW, 150-hour-per-week operating schedule. The University of Missouri submits to the US Nuclear Regulatory Commission an application for a 20-year renewal of License No. R-103.

4 2 Original Design and Construction Six Contractors: Two for design and construction, and four for construction and testing. Reactor preliminary design study, final design and design specifications were provided by the Internuclear Company of St. Louis, Missouri. Design of the laboratory and reactor containment buildings was provided by C.L.T. Gabler and Associates of Detroit, Michigan. Final engineering design, fabrication and the installation of the reactor system was accomplished by the General Electric Company (GE), Atomic Power Equipment Department, San Jose, California. B.D. Simon Construction Company of Columbia, Missouri was a subcontractor to GE to assist in the installation of the reactor system.
