cooperation of the International Atomic Energy Agency (IAEA), neutronic
calculations were carried out for conversion of the IAN-R1 Reactor from MTR-HEU
fuel to TRIGA-LEU fuel. In order to establish a staff for neutronic calculation
at the Instituto de Ciencias Nucleares y Energías Alternativas (INEA) a program
was established. This program included training, acquisition of hardware,
software and calculation for the core
with MTR-HEU fuel , enriched nominally to 93% and calculation for
several arrangements with the TRIGA-LEU
fuel, enriched to 19.7%. The results were verified and compared with several
groups of calculation at the Instituto
Nacional de Investigaciones Nucleares (ININ) in Mexico, and General
Atomics (GA) in United States. As a result of this program, several technical
reports have been wrote.
