Brookhaven Medical Research Reactor
The last of the Lab’s reactors, the Brookhaven Medical Research Reactor (BMRR), was shut down in December 2000. The BMRR was a three megawatt (thermal) reactor that was 1,000 times smaller than the typical power reactor. It reached criticality on March 15, 1959 and was used specifically for medical research. On January 28, 2003, the fuel (41 elements) and four control rods were removed and transported by truck to DOE's Savannah River Site. Currently, the BMRR remains in a "cold" shutdown mode and is awaiting decommissioning.
