Reducing the Use of Highly Enriched Uranium in Civilian Research Reactors (2016)

Appendix F

HEU-Fueled Reactors Outside the Scope of the Study

A s part of the effort to identify the civilian reactors operating on highly enriched uranium (HEU) fuel listed in Table 2.2, the committee also collected information on operational reactors that are considered outside the scope of this study (Arkhangelsky et al., 2012; Chamberlin, 2015; IAEA, 2000). This appendix lists reactors that are out of scope in Tables F.1 and F.2 including 30 defense-oriented (research) reactors and 9 civilian propulsion reactors. These lists may not be complete and should be considered noncomprehensive because publicly available information may be incomplete or out of date (e.g., with regard to the operational status of particular facilities).

The 2009 Academies study (NRC, 2009, p. 162) recommended that:

DOE-NNSA [Department of Energy–National Nuclear Security Administration], in cooperation with IAEA [International Atomic Energy Agency], make an effort to maintain an up-to-date and comprehensive database of the research and test reactors of the world, including . . . reactors with a defense-oriented mission, [but not including (military) naval propulsion reactors]. . . . these reactors should be investigated to determine if it is feasible to convert them to LEU [low enriched uranium]; if so, they should become in-scope for the [GTRI (Global Threat Reduction Initiative), now M³ (Material Management and Minimization)] program.

TABLE F.1 Operational Defense-Oriented (military) Reactors Using HEU Fuels

^a The column labeled “IAEA ID” shows the IAEA’s Research Reactor Database (RRDB) numbering, if it exists for a listed reactor. If an IAEA ID is not known, then the cell is blank.

^b Two dual-use reactors, Ruslan and Lyudmila (LF-2), are tritium production reactors that produce isotopes for the civilian market.

NOTE: Key to acronyms in table for “Type” of reactor: CA = critical assembly; NV = naval reactor; PR = pulsed reactor; SS = steady-state; DUAL = both military and civilian use; and IB = icebreaker.

TABLE F.2 Operational Civilian Propulsion Reactors Using HEU Fuels

^a The column labeled “IAEA ID” shows the IAEA’s Research Reactor Database (RRDB) numbering, if it exists for a listed reactor. If an IAEA ID is not known, then the cell is blank.

NOTES: Key to acronyms in table for “Type” of reactor: IB = icebreaker, TS = transport ship.
