2 CHART OF SANTIAGO The Association of Latin American Nuclear Physics and Applications (ALANPA) was formed in Santiago, Chile on Dec. 19, 2009, by representatives of Argentina, Brazil, Chile, Colombia, Mexico, Peru and Venezuela. In Spanish is called Asociación Latino Americana de Física Nuclear y Aplicaciones ALAFNA In Portuguese is called Associação Latino Americana de Física Nuclear e Aplicações ALAFNA Chairs of ALANPA: Andrés Kreiner (Argentina) Alinka Lépine-Szily (Brazil)

3 Steering Committee (SC) of ALANPA is formed by the 15 original founders : Ricardo Alarcon (Arizona State Univ., USA) Hugo Arellano (U. of Chile, Chile) Haydn Barros (U.Simon Bolivar, Venezuela) Maria Ester Brandan (UNAM, Mexico) Roelof Bijker (UNAM, Mexico) Laszlo Sajo Bohus (U.Simon Bolivar, Venezuela) Fernando Cristancho (UNal, Colombia) Paulo Gomes (U.

48 Física nuclear y aplicaciones en el Perú El Instituto Peruano de Energía Nuclear (IPEN) cuenta con un reactor de investigación de 10 MW, en el cual se produce radioisótopos para medicina y se realiza análisis químicos por activación neutrónica. Se tiene también una facilidad de neutrografía. El IPEN en colaboración con la Universidad Nacional de Ingeniería se realiza simulación de experimentos de fisión y experimentos de física de reactores. Un grupo de la Pontifica Universidad Católica del Perú trabaja en el experimento ALICE con el grupo de México en el CERN.

49 Conclusions: Most countries in the region have small activity in basic Nuclear Physics research. Mostly radiation and medical applications. Very small number of scientists. Exceptions: Argentina, Brazil, Mexico Region has no large scale facilities in NP and no plans. Small support from funding agencies even for maintenance of existing facilities.
