Competence
The profile combines practical technical field work with advanced analysis and physics-based modelling. It is the combination – not either side in isolation – that creates the unique value: the ability to understand a system in reality and recreate it analytically.
The working style is defined by moving from observation to understanding: reading real systems in operation, identifying the governing relationships, and translating them into models, analyses, and decision support that hold up technically.
Profile and CV
Senior systems engineer, Lic. Eng.
Antanas Romas, Lic. Eng., is a senior systems engineer with 25 years of experience in the nuclear industry. The centre of gravity is advanced modelling, verification and the development of reactor models for full-scope simulators, with particular strength in reactor physics and thermal hydraulics.
The profile combines deep specialist knowledge from safety-critical environments with the practical ability to reconstruct, analyse and verify complex technical systems - from real facilities to simulator-based environments and training contexts.
Core competence
Field analysis and measurement
- Inspection and measurement in real plants
- Thermography, flow measurement, pressure and temperature
- Reconstruction without complete documentation
System reconstruction
- System mapping based on observations
- Identification of real connections and dependencies
- Basis for model and analysis
Analysis and modelling
- Physics-based models and digital twins
- Transient analysis and dynamic processes
- Parameter studies and sensitivity analysis
Root cause identification
- System dependencies and causal relationships
- Comparison against real behaviour
- Concrete, implementable corrective actions
Verification in operation
- Measurement against expected behaviour
- Start-up and functional checks
- Documentation of verification results
Nuclear and full-scope simulators
- Development of reactor models for full-scope simulators
- Reactor physics, thermal hydraulics and dynamic behaviour
- Verification in safety-critical and simulator-based environments
Delivery capability
- Concrete action proposals: implementable recommendations grounded in the system's real conditions.
- Traceable decision support: clear assumptions, method and version ID – adapted for review.
- Reproducible analysis packages: scripts, notebooks or calculation templates the customer can re-use.
- Training material: pedagogical models, simulators and documentation adapted to the recipient.
- Risk-adapted quality assurance: from rapid expert input to extended verification and peer review.
