Shaw/AREVA MOX Services (MOX Services) is designing and constructing the Mixed Oxide Fuel Fabrication Facility (MFFF) at the Savannah River Site for the Department of Energy. The piping design for this facility requires the use of Titanium and Zirconium materials in some piping systems. MOX Services requires approximately 1300' of Titanium pipe in sizes ranging from 1/4" to 1-1/4" NPD and approximately 1600' of Zirconium pipe in sizes ranging from 1/4" to 5" NPD. See below for quantities by pipe size. An assortment of fittings will also be needed for each material and size to support pipe fabrication. The schedule of supply begins in May 2010 to support the fabrication schedule. The supplied pipe and fittings shall be certified as meeting the Buy American Act (FAR 52.225-11 Buy American Act - Construction Materials under Trade Agreements (NOV 2006) and shall conform to the primary technical requirements provided below.

(1) - Pipe shall be ordered as "minimum wall" order method with the minimum wall thickness being the nominal wall thickness associated with the specified pipe schedule in this column and for the given NPD.

QA PROGRAM REQUIREMENTS:
** MOX Services is committed to the regulator (Nuclear Regulatory Commission) to perform work in accordance with 10CFR50 Appendix B, NQA-1 Part I, basic and supplemental requirements, Part II and Appendix 2A-1 of Part III, and Regulatory Guide 1.28 Revision 3. The supplier of the piping will be required to meet the requirements to the extent they are applicable to the supplier's scope of work. These requirements must be flowed down to any sub-suppliers along with the requirement for the sub-supplier to flow down.
