The scope of the Mixed Oxide (MOX) Project includes the design, construction, and operation of the MOX Fuel Fabrication Facility (MFFF). The MOX facility will convert nuclear weapons based highly enriched uranium and plutonium into low-enriched nuclear reactor fuel. This design, construct, and operate activity requires obtaining Nuclear Regulatory Commission (NRC) licensing and necessary Federal, State, and Local operating permits; supplying commercial grade nuclear fuel for mission reactors; safeguarding plutonium dioxide powder feedstock and fresh MOX fuel; and ultimately deactivating the facility.

Administrative, Engineering, Professional, and Technical Support Services

In November, 2006 Shaw/AREVA MOX Services, LLC (MOX Services) awarded HukariAscendent (previously Ascendent, LLC) a Basic Ordering Agreement to provide Professional, Technical and Administrative support services for the MOX Project. The contract included a two-year base period and 3 one-year options. The design and construction of the MOX Project phases was expected to be completed in 2013. On May 23, 2008 Shaw Areva MOX Services, LLC and the U.S. Department of Energy (DOE) signed an agreement implementing construction of the MOX Facility. Through this agreement, valued at nearly $2.7 billion, the DOE exercised the construction option that was included in the design contract signed in 1999. The agreement’s scope included the actual construction of the main MOX facility and all support facilities; cold start-up of the MOX plant; and continued support of Nuclear Regulatory Commission licensing activities associated with the project.

  • HukariAscendent provided staff augmentation services during 2007 – 2012 with follow-on work through 2013. Licensing and engineering services support included combined DOE/NRC facility licensing, design review, safety analysis and Safety Basis document development, and Failure Mode and Effects Analysis (FMEA).
  • More than 150 technical and professional personnel placed during the 4-year contract period.
  • HukariAscendent employees worked on-site in various engineering, design, safety and licensing support positions including nuclear criticality safety, radiological safety, process engineering, civil/structural engineering, electrical engineering, HVAC engineering, I & C engineering, welded equipment engineering, seismic engineering, pipe stress analysis, procurement engineering, piping design, electrical design, structural design, drafting, support modeling, root cause analysis, and engineering supervision.
  • Provided support to the Integrated Safety Analysis (ISA) associated with NRC licensing of the MFFF. Performed safety evaluations that demonstrated MFFF satisfied the requirements of 10 CFR 70.61 for Pu and chemical hazards associated with Purex type process systems. Identified hazards, performed analyses and developed models necessary to support the ISA. Prepared process hazard analyses for MOX chemical process systems.
  • Provided on-site Commercial Grade Dedication (CGD) engineering services support, including a detailed assessment of MOX Services’ CGD program and process as defined by PP09-18, “Commercial Grade Item Evaluations”, Revision 2, with a particular focus on potential industry issues related to new construction. The assessment required a comprehensive evaluation of the client’s CGD program elements, implementation of the program, and identification of specific program strengths and weaknesses, and providing recommendations for improvement.
  • Provided engineering and design of specialty processes, systems and components for highly complex, highly regulated plutonium uranium and processing facilities, systems and components involving extensive nuclear and criticality safety controls, assessments and design features.
  • Disposition of Non-Conformance Reports to mitigate design and code violations. Performed daily field surveillances requiring interface between and with construction, QA/QC, NRC, design and field engineers.
  • HukariAscendent Senior Manager assigned to Project with responsibility for management of 100 HukariAscendent employees on-site and managed a local office in Aiken, SC.

The MOX Project management nominated HukariAscendent (previously Ascendent, LLC) for the DOE Small Business Administration Award for Excellence in 2007.
