SIMS Specialist(P3)


  • Organization: IAEA - International Atomic Energy Agency
  • Location: Vienna
  • Grade: Mid level - P-3, International Professional - Internationally recruited position
  • Occupational Groups:
  • Closing Date: 2023-04-16

Organizational Setting

The Department of Safeguards carries out the IAEA’s duties and responsibilities as the world’s nuclear inspectorate, supporting global efforts to stop the spread of nuclear weapons. The primary role of the Department is to develop and implement IAEA safeguards to ensure that there is no diversion of declared nuclear material from peaceful activities and no indications of undeclared nuclear material or activities in a State as a whole.

The Department comprises nuclear safeguards inspectors, responsible for carrying out inspections and verifications of all-safeguards relevant information for nuclear facilities in over 180 States; and technical staff responsible for a wide range of activities including\: developing concepts and approaches for implementing safeguards; developing and maintaining safeguards equipment; providing analytical and laboratory services for sample analysis; collecting, evaluating and analysing safeguards-relevant information; providing information and communication technology infrastructure and services; and providing programme coordination support.

The Office of Safeguards Analytical Services (SGAS) is responsible for the analysis of inspection samples collected in the field. Located about 45 km south of Vienna in Seibersdorf, SGAS is organized into three sections\: the Nuclear Material Laboratory (NML), the Environmental Sample Laboratory (ESL) and the Coordination and Support Section (CSS). The laboratory sections conduct the screening, chemical treatment and measurement of the inspection samples. The Coordination and Support Section provides a variety of key services to the laboratories, as well as managing the network of analytical laboratories. SGAS also manages analytical and inspection activities in a dedicated On-Site Laboratory at the Rokkasho Reprocessing Plant in Japan.


Main Purpose


Reporting to the Team Leader of the Microparticle Analysis (MPA) Team, the SIMS Specialist implements operational aspects of the MPA team for the analysis of uranium particles in environmental samples (ES) by Large-geometry Secondary Ion Mass Spectrometry (LG-SIMS), Scanning Electron Microscopy (SEM) and other related techniques. The SIMS Specialist contributes to quality management activities through innovative process improvements in analysis and the production of particle Quality Control (QC) materials.




The SIMS Specialist is\: (i) a technical specialist performing isotopic measurements using LG-SIMS and other techniques, and seeking opportunities for the continual improvement of existing analytical procedures; (ii) a technical expert contributing to the diagnosis of technical issues, the development and maintenance of complex software tool for data processing and the tuning and alignment of the instrument; (iii) a team player who ensures that all team operations are performed in compliance with IAEA regulations and laboratory best practices..


Functions / Key Results Expected


Participate in the preparation and analysis of uranium particles in safeguards environmental samples, using LG-SIMS, SEM and other related techniques;

Ensure the quality of analytical results by developing and following analytical procedures and QC charts, while seeking opportunities for continual improvement to laboratory methods and techniques;

Contribute to the production and characterization of particle QC materials for internal and external quality control programs;

Ensure the analytical and ancillary equipment is maintained at the adequate level to provide fit-for-purpose analytical results;

Contribute to the maintenance and operation of the laboratories to ensure the required quality standards;

Keep abreast of developments in the field of environmental sample analysis and contribute to the implementation of new techniques and improved methodologies (e.g. Laser Ablation Inductively-Coupled-Plasma Mass Spectrometry, LA-ICPMS).
