Nuclear Services

A significant portion of PROCESS’ work emanates from the nuclear materials processing industry: nuclear materials production/reprocessing support, process engineering design, environmental compliance, and waste management.

Our plant operations and process design experience is quite extensive and, because our company is focused only on chemical engineering, we are very good and efficient at the services we provide.  We have been regularly subcontracted for work supporting the missions of the Oak Ridge National Laboratory (ORNL), the Y-12 National Security Complex, the Savannah River Site, and the Hanford Site. PROCESS has also performed work in support of the Atomic Energy of Canada Limited (AECL) and private nuclear material manufacturers.  Projects have been in the areas of design definition and implementation, process design development, specialized computer modeling calculations, operational troubleshooting, and system engineering support.  Our work has included the design and operation of processes for various depleted and enriched uranium compounds, including Category II nuclear material as well as associated contaminants and daughter products, and nuclear waste. We are familiar with the stringent requirements associated with the implementation of strict nuclear criticality safety design constraints, conduct of operations, and configuration control management.  We have been successful in interactions with oversight organizations such as the Department of Energy (DOE), Nuclear Regulatory Commission (NRC), and the Defense Nuclear Facilities Safety Board (DNFSB).

 

 

 

 

 

 

Operational Planning:  Anticipating operational needs, PROCESS reviews the on-going design with an operating eye as it is implemented during construction.

  • Operating Mode Summary (OMS)
  • Bottleneck analysis
  • Vendor package review
  • Conduct of Operations planning
  • Project Change control

 

 

 

Startup Operations:  Field support of operating the process requires an understanding of how a process works and what its safety envelope is. PROCESS is experienced in establishing and protecting the technical baseline of the process.

  • Operating procedures for normal and abnormal conditions
  • Test procedures
  • Operational Readiness Review (ORR) preparation
  • Field startup testing
  • Unresolved Safety Determinations (USQDs)
  • System verification

Our Nuclear Niche

We address the full spectrum of process engineering services over the system life cycle of a process, from the initial stages of design definition, through detailed process design and operational startup/support, and through decommissioning and closure. The effective use of process engineering as a discipline, when utilized throughout the process lifetime, can serve as an integrating discipline to help ensure that the technical baseline is defined and maintained.

Process Design Definition:  Definition of the overall process system and technical requirements, predicting expected process behavior through modeling and simulation, evaluating viable alternatives. Process design provides the roadmap / blueprint for other design disciplines to follow.

  • Strategic planning support
  • System Requirements Document (SRD)
  • Technical baseline development
  • Design Criteria development support
  • Feasibility /alternatives study
  • Block Flow Diagrams (BFDs)
  • Conceptual design
  • Process simulation and analysis
  • Material and Energy balances
  • Process Flow Diagrams (PFDs)
  • Process Hazard Analyses (PHA)
  • Safety basis development
  • Integrated Safety Analysis (ISA) support
  • NRC Licensing support

 

Detailed Process Design:  Process flowsheet is refined and design details are developed. This stage of design is highly interactive between design disciplines, with the process discipline responsible for helping to ensure the process baseline remains in compliance with the established design criteria.

  • Piping & Instrumentation Diagrams (P&IDs)
  • System Design Description (SDD)
  • Waste management plans
  • Environmental compliance reviews
  • Nuclear Criticality Safety design implementation
  • Safety basis implementation
  • Equipment specifications and datasheets
  • Hydraulic flow calculations
  • Design Analysis Calculations (DACs)
  • Compliance with NQA-1 standards
  • System integration
  • Interface coordination
  • HAZOP detailed analysis
  • Quality Level assessment and assignment

 

 

 

 

 

 

Operations and Decommissioning: Continual improvement of operations may result in system expansions or process shutdowns. Such system changes can be implemented in a logical manner which minimizes the downtime of interfacing processes.

  • Process assessments
  • Conduct of operations implementation
  • Occurrence reporting input
  • RadWorker experience
  • Decommissioning
  • Hazard evaluations
  • Shutdown / decommissioning procedures
  • Field oversight activities

 

 

PROCESS has provided these services to DOE and AECL facilities and nuclear production sites in both the commercial and government realms. Our Q-cleared engineers have extensive DOE and NNSA experience providing chemical process design, process modeling and simulation, startup operations support, ongoing operational troubleshooting / optimization, and decontamination & decommissioning support. We are familiar with stringent Conduct of Operations and Project Control procedures, have created, implemented, and maintained Safety Authorization and Technical Basis documentation, and have successfully interacted with the Defense Nuclear Facilities Safety Board and other stakeholder organizations.

A Great Project Partner for Detail Engineering Companies

PROCESS is not a placement agency or loose group of consultants, we are a specialized engineering firm. Our engineers have performed client work under task-specific, staff-augmentation, and seconding subcontracts. On average our process engineers have over 20 years of experience and all of them have some background in plant operations which we feel is an invaluable asset to our clients.

We offer the full spectrum of process chemical engineering services for nuclear processes at several different commercial and government sites. View an Overview of Nuclear Experience here.
