Job description

What we do at Blykalla

Blykalla is a Swedish deep-tech company at the forefront of the nuclear industry, pioneering the development of small modular reactors that provide clean, safe, and reliable energy. Thanks to lead-cooling, we achieve high safety in a very compact format, allowing for a simple and cost-effective design that can be mass-produced. Our unique reactor design will provide safe and green baseload energy that perfectly complements solar and wind power.

What you’ll get to do

We're seeking an experienced Nuclear Safety Engineer within deterministic safety analysis to join our Nuclear Engineering & Safety team in Stockholm. In this role, you will analyze the safety case for our lead‑cooled fast reactor designs, using deterministic methods on transient and accident conditions. An important part of the job is to document your work with the aim of supporting regulatory interactions, thereby ensuring that our SMRs meet and demonstrate the highest level of nuclear safety throughout design, licensing, and deployment.

• Develop and maintain the deterministic safety analysis case for our cutting‑edge lead‑cooled fast reactor designs
• Perform simulation and analysis of transient and accident conditions using computer codes such as Bella, Apros and Spectra, as well as fuel performance and/or CFD tools, depending on skills and interest.
• Develop and maintain a transparent and efficient ecosystem of computer codes, plant models, verification & validation cases and all associated documentation.
• Prepare safety analysis reports and technical submittals for regulatory review
• Stay current with advances in safety methodologies, computer codes, regulatory requirements, and international standards
