The proposed action would modernize the argon purification system in the Hot Fuel Examination Facility (HFEF) at the Materials and Fuels Complex (MFC) building MFC-785. The HFEF argon purification system consists of three basic parts: 1) analytical system, 2) hydrogen injection system and 3) purification/regeneration system. The project would use a phased approach, completing upgrades to the three parts of the air purification system individually in the order previously listed. The proposed action would install a temporary analytical cabinet in the appropriate areas of HFEF and connect it to the associated portions of the purification system. Once the temporary system is functional, the analytical cabinet would be removed and a new cell analytical system installed. Once the new analytical system is installed and functional the temporary system would be removed. Phase 2 and 3 of the system would be implemented as time permits during facility outages. The modernization is to replace obsolete equipment with modern equivalents.
