Lead Nuclear Safety Engineer

  Alkmaar    Fulltime

Who is PALLAS?

Every day, 30,000 patients depend on medical isotopes from Petten. In order to guarantee security of supply in the future, preparations are now being made for the construction of the PALLAS-reactor and the realisation of the Nuclear Health Centre.

The Foundation Preparation Pallas-reactor (PALLAS) aims to realize a 'state-of-the-art' multifunctional reactor, which will be designed for the production of (medical) isotopes and for nuclear technological research. This reactor will replace the current High Flux Reactor (HFR) in Petten (NL). With the HFR, NRG produces medical isotopes with which doctors all over the world diagnose and treat life-threatening diseases such as cancer and cardiovascular diseases. The Nuclear Health Centre will process and package medical isotopes into radio chemicals and radiopharmaceuticals (medicines). The development of this production facility runs parallel to the realisation of the PALLAS-reactor.

The Foundation NRG and PALLAS are working closely together. The management and supervisory boards of both organizations are now united, and steps are being taken to further integrate the two foundations. This will give the development of medical isotopes in Petten and the realization of the new reactor a strong impulse. NRG leads the world in research into new nuclear technologies. In addition to the new reactor, other initiatives are being developed. For an overview of these, we invite you to visit: https://www.pallasreactor.com/en/pallas-activities/.

PALLAS employs people from all over the world, creating a unique combination of knowledge and experience. We are constantly building on our safety culture and ensure that objectives in the areas of safety, security and quality are always met.


The Lead Nuclear Safety Engineer is part of the Safety Demonstration team which is responsible for a suitable PALLAS Safety Demonstration. He or she contributes to PALLAS:

o Acting as an Intelligent Customer by maintaining oversight of the Safety Demonstration;

o Becoming an Intelligent Owner and Operator by gradually taking ownership of the Safety Demonstration.

The Safety Demonstration is the suite of documents that contain the claims, arguments and evidence necessary to demonstrate that the organisation and its facilities are acceptably safe at all stages during their lifetime. The main document is the Safety Analysis Report.

The Safety Demonstration provides PALLAS with the assurance that the highest safety standards that can reasonably be achieved are met. It is used as one of the major inputs for the nuclear licensing framework of the PALLAS-reactor.

Where PALLAS has contracted a third party to perform safety analyses and to prepare parts of the Safety Demonstration, PALLAS conducts safety reviews and analyses on its own to verify their outputs.

This job is a full-time (40 hours per week) position. The Safety Demonstration team consists of five colleagues and is supported by NRG and our Owner’s Engineering team for specific tasks. You will report to the Safety Demonstration Manager.


The Safety Demonstration team members contribute to ensure that PALLAS achieves efficient evidence to support the safety claims and arguments as part of the Safety Demonstration. They also check that the design complies to relevant safety requirements.

As a Lead Nuclear Safety Engineer, you are responsible for:

  • Supporting the further development and maintenance of the Safety Demonstration process and related procedures of PALLAS IMS in particular by defining the process for the update and maintenance of the SAR;
  • Setting clear requirements, expectations and acceptance criteria towards the Safety Demonstration within PALLAS and all relevant stakeholders;
  • Performing verification activities of safety related documentation to ensure PALLAS efficiently obtains evidence to support the safety claims and arguments of the Safety Demonstration;
  • Contributing to the compliance check of regulatory and (project and technical) safety requirements in collaboration with the members of the PALLAS Safety Demonstration, Engineering and Licensing and Compliance teams;
  • The planning for and the preparation of the SAR in line with detailed design information and information on the commissioning and operation of the reactor (e.g. operating and emergency procedures, operating limits and conditions, operating organization structure, etc.) with as one of the main objectives, to obtain the license to commission and operate the reactor;
  • Ensuring overall consistency and balance of the Safety Demonstration and that the links between the safety requirements, claims, arguments and evidence are accurate, logical and complete;
  • Ensuring that Requests for Additional Information from the ANVS are properly addressed.

The Lead Nuclear Safety Engineer is overall responsible for checking that:

  • All possible radiation risks are identified;
  • The items important to safety are identified and requirements commensurate with their importance to safety are identified;
  • The technical safety concepts e.g. the DiD concept are adequately implemented;
  • Regulatory and safety requirements (i.e. Bkse, Bbs, DSR, SSR-3) are complied with in collaboration with other Safety Demonstration team members, the engineering team, the licensing and compliance team and any other relevant PALLAS team members;
  • Sufficient safety margins are provided.

PALLAS considers personal development and sustainable employability important for its employees. You will experience that the work has a high degree of variation and challenges, with many opportunities to learn and grow.
