INTRODUCTION
Within the ARIEL project (H2020 ARIEL EU project (ariel-h2020.eu)) the Johannes Gutenberg University in Mainz will organize a Lab Course in Reactor Operation and Nuclear Chemistry to be held November 19-24, 2023. The course is open for advanced Master students. PhD students and Post-Docs working in the the field of chemistry, physics, nuclear engineering and related areas.
The participants will learn how to operate the TRIGA Mainz research reactor in steady state as well as in pulsed mode and study the effect Cd-samples on the reactivity. In short term irradiation of an Os-sample and subsequent gammaspectroscopical analysis low lying rotational bands in Os-190m are studied. Furthermore ß-delayed neutron measurements using He-3 counting tubes are planned. For this, samples of U-235 and Th-232 are irradiated with and without Cd-shielding. In the Nuclear Chemistry part of the course the participants will repeat the classical experiment of Otto Hahn and Fritz Strassmann that led to the discovery of nuclear fission as they confirm chemically that barium is formed during the irradiation of a U-235 solution with thermal neutrons.The experimental programe will be accompanied by a series of lectures about the discovery of nuclear fission, applications of research reactors for science and industry and the operation and the special design features of TRIGA reactors. Furthermore, a lecture about the OKLO-reactor is planned.
PARTICIPANTS
The school is open for up to 10 participants. The target audience are advanced Master students. PhD students and Post-Docs working in the the field of chemistry, physics, nuclear engineering and related areas. The selection of the 10 participants is the responsibility of the International Advisory Committee and will be based on the information given in the "Letter of Interest" to be provided in the registration process.
