What you’ll get to do
Our team at Blykalla is looking for a materials specialist with deep expertise in fuel cladding, fuel-cladding interaction and irradiation effects. You will define how our cladding behaves inside the core, how the cladding reacts chemically with uranium fuel on the inside and liquid lead on the outside, and how the material changes under neutron irradiation. Your work decides which cladding we can qualify, and how to get the data needed.
You join the materials team as the technical owner for qualifying the fuel cladding. The cladding is the first barrier around the fuel, and it must keep its integrity for the full core life in a hot, irradiated, liquid-metal environment. You will work closely with the fuel, core design, and safety analysis teams as well as research institutions across Europe and the US.
Responsibilities
Own the technical basis for the cladding material and its corrosion-protective layer, from specification through qualification.
Assess and test fuel-cladding chemical interaction with uranium fuel, including carbon and nitrogen transport.
Assist with the irradiation programme to ensure all needed data is gathered. Interpret post-irradiation examination data on hardening, embrittlement, swelling, irradiation creep and helium effects.
Turn test results into design limits and lifetime models, together with the core design and fuel teams.
Map nuclear codes and standards, such as ASME Section III Division 5, onto cladding qualification, and contribute to the safety case for licensing with SSM and NRC.
Write and review technical reports and data packages and keep the team manager and other projects updated on progress, challenges and risks.
Who you’ll get to work with
The Materials Specialist sits in the Materials Engineering Team within Blykalla, and reports to the Head of Materials. We are a diverse team that is passionate about our work and Blykalla.
Who you are
You will be part of a highly skilled team with a can-do attitude. We value personnel chemistry and strive to create a workplace where you enjoy coming to. There are however a few things that we think will help in order for you to succeed in this role, these are:
Master’s degree or PhD in materials science, nuclear engineering or a related field.
Proven experience with fuel cladding materials for fast reactors or other advanced reactors, including fuel-cladding chemical interaction.
Solid understanding of irradiation effects in steels and how they translate into design limits and qualification requirements.
Hands-on experience of microstructural analysis.
Experience working with test reactor operators, research institutes or suppliers on material development.
Fluency in English, spoken and written. Swedish is an advantage.
Nice to have
Experience with various fuel systems.
Knowledge of liquid metal corrosion and liquid metal embrittlement.
Experience with ferritic, FeCrAl or oxide-dispersion-strengthened steels, or with thermal spray and laser cladding of tubes.
Familiarity with ASME, RCC-MRx and nuclear quality assurance requirements such as NQA-1.
Experience with fuel performance or materials modelling.
Salary range is flexible based on candidate profile, our band is from 57 000 - 75 000 sek/monthly.
Location
This position is for our office in Stockholm.
