Engineering Excellence

Nuclear Safety & Licensing

From DOE facilities to commercial fuel cycle operations, we provide rigorous engineering analysis and regulatory support that ensures safety basis compliance and operational success.

Safety Basis

Nuclear Safety Analysis

We provide comprehensive safety analysis for DOE facilities and commercial plants. Our team specializes in identifying hazards and defining the controls necessary to operate safely within the regulatory envelope.

  • Criticality Safety Evaluations
  • Integrated Safety Analysis (ISA)
  • Process Safety Analysis
  • Design Basis Accident Analysis
  • Chemical and Radiological Consequence Analysis

Deterministic & Probabilistic

Our engineers are adept at both deterministic safety analysis and risk-informed methodologies tailored to 10 CFR 70 and 10 CFR 830.

NRC & DOE Liaison

We don't just write reports; we defend them. Our team has extensive experience interacting directly with NRC reviewers and DOE oversight boards.

Regulatory Compliance

License Application Development

Navigating 10 CFR 70 requires a multi-disciplinary approach. We manage the development of License Applications and ISA Summaries for fuel cycle facilities, covering every safety discipline required by the NRC.

  • Radiation Protection
  • Chemical Safety
  • Fire Protection
  • Emergency Management
  • Environmental Characterization
  • Material Control & Acctg.
  • Physical Security
  • Decommissioning Funding
Strategic Economics

Reactor Design & Cost Analysis

Balancing safety with economic viability is critical for next-generation nuclear deployment. We employ advanced modeling to assess the financial and safety risks of new reactor designs and fuel cycle processes.

  • Probabilistic Risk Assessment (PRA)
  • Quantitative Risk Assessment (QRA)
  • Fuel Cycle Cost Analysis
  • Reactor Design Cost Modeling

Data-Driven Decisions

Utilizing Monte Carlo simulations and economic modeling to optimize design trade-offs before concrete is poured.

Advanced Systems Modeling

We utilize industry-standard codes for high-fidelity simulation and analysis.

Quality Commitment

NQA-1 Compliant Assurance

In the nuclear industry, quality isn't just a goal—it's a requirement. DeMase Technical Services operates under a rigorous Quality Assurance Program (QAP) designed to meet the most stringent standards.

Our QA program ensures that all safety analysis, software calculations, and engineering designs are traceable, verifiable, and defensible in front of regulators.
