  About the job

  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. More specifically, you will:

  • 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

  
  

  Who'll you'll get to work with

  The Nuclear Safety & Licensing Engineer sits in the Nuclear Engineering & Safety team within Blykalla, and reports to the manager of Nuclear Engineering & Safety.

  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 in engineering, physics, or related field
  • 5-10 years of experience in deterministic safety analysis for any commercial reactor types
  • Strong understanding of reactor safety principles, defense-in-depth, transients and accident phenomenology
  • Familiarity with regulatory frameworks (SSM, NRC, IAEA, or equivalent) and licensing processes
  • Excellent analytical, problem-solving, and technical writing skills
  • Fluent in English, spoken and written
  • Fluency in Swedish, spoken and written

  If you are not sure that you are 100% qualified but are up to the challenge, we encourage you to apply.

  Location

  This position is for our office in Stockholm.

  So, what do you think?

  Don't miss the chance to be at the forefront of revolutionizing nuclear power. Join our team as a Nuclear Safety Engineer and help shape the energy landscape of tomorrow. Apply today with your resume and a cover letter highlighting your relevant experience and achievements.

  We are proud to foster an inclusive workplace free from discrimination. We strongly believe that diversity of experience, perspectives, and background will lead to a better environment for our employees and a better product. This is something we value deeply and we encourage everyone to be a part of changing the way the world thinks about power supply!
