Sander de Groot has been working at NRG for over 20 years, the last 4 years as program manager medical isotope development. In this program, high potential reactor produced isotopes have been selected, and the irradiation and separation/purification processes have been developed. These processes are currently being implemented in the FIELD-LAB, a consortium of academia, SME and industry, in which the isotopes are used for acceleration of radiopharmaceutical product development. NRG is establishing dedicated FIELD-LAB infrastructure at the Petten site, where also the High Flux Reactor Petten is located.
