RA-1 Enrico Fermi
RA-1 Enrico Fermi is a research reactor in Argentina and the first nuclear reactor to be built in that country. Construction started April 1957, with first criticality 17 January 1958. It produced the first medical and industrial radioisotopes made in Argentina, and was used to train staff for the first two nuclear power stations there.
It is a pool type, with enriched uranium oxide fuel (20% U-235), light water coolant and moderator, and a graphite reflector. It produces 40 kilowatts of thermal energy at full authorised power.
It has been modernised on several occasions, and is currently used for research and teaching.
