Savannah River Site Fabrication Facility

The Challenge

Shaw AREVA MOX Services, LLC, is designing and constructing the Mixed Oxide (MOX) Fuel Fabrication Facility for the U.S. Department of Energy (DOE). The facility will take surplus weapon-grade plutonium, remove impurities and mix it with uranium oxide to form MOX fuel pellets for reactor fuel assemblies. These assemblies will be irradiated in commercial nuclear power reactors.

Intermech has been selected to detail and fabricate several mechanical systems components to date for the MOX project that have included Quality Level 1 (QL-1) requirements, including the Release 3 Piping Embeds.

The Release 3 Piping Embeds fabrication included both QL-1 and QL-4 piping spools. Intermech performed this fabrication in its McLeansville, NC fabrication facility. This facility is approved by Shaw AREVA MOX Services, LLC for QL-1 fabrication and is currently performing additional scopes of work for the MOX Project.

Intermech's Response

Under its NQA-1 program, Intermech detailed, fabricated, tested and delivered completed QL-1 and QL-4 stainless steel piping spool fabrications that were for installation in the structural construction of the Mixed Oxide (MOX) Fuel Fabrication Facility.

The Results

Intermech successfully detailed and pre-fabricated various stainless steel piping assemblies involving radiographic (RT) quality welds and cold bending within strict contract delivery deadlines and in accordance with rigorous project quality requirements. The scope of work performed had a contract valuation of over $600,000 and was executed from January of 2008 through May of 2009. As a result of Intermech's performance on this contract, the Company has continued to receive multiple NQA-1 fabrication contracts on the MOX Project with total contract valuations exceeding $20 million to date.

This project demonstrates:

• Quality – NQA-1 Standards
• Fabrication – Safety Significant Systems (Quality Level 1)
• Personnel Experience
• Project Controls & Scheduling
