Nuclear Safety

Ensuring nuclear surety and safety for our clients through:

  • Safety Basis. Sigma’s capabilities include development and implementation of Technical Safety Requirements (TSR), Documented Safety Analyses (DSA), Safety Analysis Reports (SAR), Nuclear Safety Analysis Reports (NSAR), Hazard Analysis Reports (HAR), and Probabilistic Risk Assessments (PRA) under DOE, NNSA, and DoD requirements, such as 10 CFR 830, DOE O 410.1, DOE O 413.3B, and DOE-STD-1189. This includes new nuclear facilities and existing facility updates, modifications, and recategorization.
  • Nuclear Criticality Safety. Sigma staff include nuclear criticality safety engineers and SMEs who perform nuclear criticality safety evaluations, criticality parameter studies, and criticality parameter sensitivity studies.
  • Operational Readiness. Sigma staff participate in management assessments and operational readiness reviews and provide conduct of operations mentoring, lessons learned, reviews, and assessments.
  • Fire Protection/Systems Engineering. Sigma staff develop Fire Hazard Analyses (FHAs); conduct initial condition assessments; support fire protection, alarm, and suppression system design and operations; conduct fire protection-related design reviews; and support fire protection system upgrades.

Nuclear Construction Services
