The High-Flux Isotope Reactor (HFIR) is a high-power-density research reactor located at the Oak Ridge National Laboratory and operated by Lockheed Martin Energy Systems for the U.S. Department of Energy. It operated at the design power rating of 100 MW from its startup in 1966 until it was temporarily shut down in 1986 for the investigation of pressure vessel embrittlement. Operation was resumed in 1989, and the primary coolant pressure was reduced from 5.3 MPa (750 psig) to 3.3 MPa (468 psig) to extend the pressure vessel service life. Also, the operating power level was decreased to 85 MW to preserve an overpower margin consistent with the original HFIR design basis.
