There were 34 civilian research reactors in operation in the United States in 2011 (Table 1-1)[21] As of June 2011, all but 8 of these reactors had been converted to LEU fuel. Two of these 8 reactors[22] appear to be convertible using current-type LEU fuels. DOE is completing studies to confirm the feasibility of converting these reactors using current-type LEU fuels. Additional research will be required to more fully develop the capability to fabricate these LEU fuels.
However, the following six reactors (including one critical assembly[23]) comprise what DOE refers to as “high-performance” reactors that pose many challenges for conversion, as discussed in more detail in Chapters 2 and 3:
• Advanced Test Reactor (ATR) at the Idaho National Laboratory
• The ATRC critical assembly associated with the ATR
• High-Flux Isotope Reactor (HFIR) at the Oak Ridge National Laboratory in Oak Ridge, Tennessee
• Massachusetts Institute of Technology Reactor (MITR) in Cambridge
• Missouri University Research Reactor (MURR) in Columbia
• National Bureau of Standards Reactor (NBSR) at the National Institute of Standards and Technology in Germantown, Maryland
New high-density LEU fuels are now under development to convert these reactors (Roglans, 2011a). These fuel development efforts are described in Chapter 2.

There were 24 operating research reactors, 30 critical assemblies, and 12 subcritical assemblies in the Russian Federation in 2011 (Bezzubtsev, 2011; see Figure 2-10 in Chapter 2).[24] Basic information on currently operating Russian research reactors is given in Table 1-2. Several civilian reactors pose substantive technical challenges to conversion, such as reactors using fuel pins consisting of UO2 dispersed in a copper-beryllium matrix with stainless steel cladding designed to operate at significantly higher fuel temperatures than most research reactors.
