CX-005187: Categorical Exclusion Determination

Hex Block Shipment Project
CX(s) Applied: B3.6
Date: 01/25/2011
Location(s): Idaho
Office(s): Nuclear Energy, Idaho Operations Office

This project involves the shipment of two irradiated stainless steel hex blocks presently located at the Idaho National Laboratory (INL) Materials and Fuels Complex (MFC) to a Westinghouse facility located in Pittsburgh, Pennsylvania to support Research and Development (R&D) activities. This research and demonstration (R&D) work will be performed by a private contractor and will involve the use of ultrasonic equipment to determine the extent of swelling in irradiated structural stainless steel. Thick sections of irradiated stainless steel (as contained in the hex blocks) are needed to verify operation of the ultrasonic measuring equipment when applied to the internals of a power water reactor (PWR). Information from the analysis will be of great value to light water reactor life extension programs and results from the analysis will be shared with the INL. Upon completion of the R&D work, the hex blocks will be returned to the INL.
