Reliability Engineer

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.

You own reliability, availability, and maintainability (RAM) engineering for Blykalla’s SEALER-55 lead-cooled fast reactor (LFR),

a 55MW small modular reactor, working within Plant Engineering across assigned plant areas, systems, and work packages. Your focus

is quantitative reliability analysis - RAM and availability modeling, reliability block diagrams, fault trees, reliability data

analysis, and FMEA / FMECA - for a nuclear plant, in close support of the probabilistic safety assessment (PSA) that underpins the

safety case. You set up the reliability framework - the RAM, FMEA, and FMECA methods, templates, criticality criteria, and data

basis - and then execute against it, making sure availability and reliability targets are defined, modeled, and flowed down into

design, redundancy and sparing, testing, and maintenance requirements. You quantify how design and maintenance choices affect

availability and lifecycle performance, coordinate interfaces with other disciplines and suppliers, and support the project from

design through procurement, construction, and handover to commissioning and operations. You also help shape a plant-as-a-product

mindset through standardization, modular design, and DfMA.

You are responsible for contributing to Blykalla’s plant engineering capability by incorporating the areas below into your daily

work:

• Set up the RAM, FMEA, and FMECA framework - methods, templates, criticality criteria, and data basis - then own and execute the

RAM scope for your areas (availability and reliability targets, redundancy and sparing philosophy, analysis basis), planning

deliverables, priorities, and resource needs.

• Define and maintain the reliability design basis, RAM targets, modeling methodology, data sources, and assumptions, working

directly in RiskSpectrum (required) for fault tree and PSA-aligned modeling, together with RAM tools such as ReliaSoft,

Isograph, GRIF, or Maros / Taro.

• Build and maintain reliability block diagrams, fault trees, and Markov / Monte-Carlo availability models, and flow reliability,

availability, and maintainability requirements down to specifications and data sheets.

• Perform and review RAM and availability studies, including RBD and fault tree analysis, Monte-Carlo simulation, spares and

logistics modeling, and lost-production analysis.

• Perform FMEA / FMECA, reliability-centered maintenance (RCM), and criticality ranking to drive design, redundancy, monitoring,

and maintenance decisions.

• Quantify the availability and lifecycle impact of design, redundancy, maintenance and test intervals, and sparing, and track

margin against targets.

• Establish reliability data and failure-rate estimates from sources such as ISO 14224 / OREDA, including Weibull / life-data

analysis and common-cause parameters.

• Provide reliability inputs - component failure data, common-cause factors, and test and maintenance assumptions - to the

nuclear PSA and safety case, coordinating closely with the function that owns nuclear safety.

• Coordinate interfaces across disciplines - process, mechanical, rotating equipment, electrical, I&C, civil and structural,

layout, safety and licensing, and operations and maintenance.

• Resolve issues around redundancy, single points of failure, common-cause vulnerabilities, testability, maintainability, and

access for maintenance, and support 3D model and design reviews.

• Set reliability and maintainability requirements for RFQs and supplier packages (targets, RAM data, FMECA, reliability

demonstration) and review supplier reliability data and reports.

• Give reliable input to estimates, schedules, risk reviews, and change requests - including the availability impact of changes -

and escalate technical risks early with practical mitigations.

• Help build a reliability engineering capability that scales with Blykalla’s project needs and supports a plant-as-a-product

mindset.

• Reliability design basis and RAM targets; reliability block diagrams, fault trees, and availability models; RAM and

production-availability study reports; FMEA / FMECA and criticality registers; RCM analyses; reliability data and failure-rate

libraries; Weibull / life-data analysis; common-cause and spares / logistics inputs; condition-monitoring and testing

requirements; reliability inputs to the safety analysis / PSA interface; supplier reliability review comments; interface

registers; change requests; and handover closeout inputs.

You are expected to keep yourself up to date with the latest advancements and continuously improve the skills of your trade, while

having in mind the expectations below.

• Bring 6+ years of experience in reliability / RAM engineering, including hands-on nuclear experience (RAM and PSA-support

analysis for nuclear plants or systems).

• Lead reliability engineering across a major plant area, a full project, or multiple complex work packages, with emphasis on

quantitative RAM modeling and analysis.

• Solve ambiguous problems by taking a broad view of technical, delivery, data, and interface constraints, and set analysis,

data, and modeling standards for the discipline.

• Technical understanding and practical application of reliability and dependability standards (IEC 60300 series, IEC 61078,

61025, 61165, 61649, 60812) and nuclear PSA practice using RiskSpectrum, with ISO 14224 / OREDA and nuclear reliability data

and applicable IAEA and regulatory guidance (for example US NRC / NUREG and Swedish SSM).

• Anticipate issues with broad impact on availability, schedule, supplier performance, commissioning readiness, or lifecycle cost

and act before they become critical.

• Give significant input to function strategy, resource planning, and ways of working across Plant Engineering, balancing

technical rigor with practical delivery.

The employee shall adhere to all governing policies, guidelines, and instructions of Blykalla such as information security policy,

acceptable use of company assets, data privacy policies, and employee code of ethics.
