Reactor Systems Engineer

  Alkmaar    Fulltime

Who is PALLAS?

The Foundation Preparation Pallas-reactor (PALLAS) is designing and building a multifunctional reactor for the production of (medical) isotopes and for conducting nuclear technological research. This reactor will replace the current High Flux Reactor (HFR) in Petten (NL) to guarantee the security of supply for millions of patients worldwide.

PALLAS wants to build its future together with Foundation NRG (NRG). We both have the ambition to continue and enforce the Dutch position as a worldwide top producer of radiopharmaceuticals in Petten, 50km north of Amsterdam in the Netherlands. We are doing this with the realisation of the FIELD-LAB (a research facility for the development of new medicines), the new PALLAS-reactor and the Nuclear Health Centre (a new production facility for processing therapeutic isotopes). The diagnosis market remains a spearhead, but the focus will mainly be on innovations and expanding the production chain for therapeutic isotopes. Through the collaboration with various national and international university hospitals and knowledge institutions, Petten is to become a breeding ground in Europe for new nuclear medicine. This results in new treatments that can help implement customised patient therapy.

PALLAS aspires to become a high-reliability organisation with the skills and capability to deliver its mission and vision through its core values, whilst ensuring that its safety, security and quality objectives are always achieved. We apply our unique knowledge and experience to benefit society by taking an interest in our stakeholders.

PALLAS is composed of colleagues coming from all over the world, bringing together a unique set of knowledge and experience.
