CX-012205: Categorical Exclusion Determination

Test Reactor Area (TRA)-640 Fire Sprinkler System Modifications
CX(s) Applied: B2.5
Date: 05/01/2014
Location(s): Idaho
Offices(s): Nuclear Energy

The Hazardous Chemical Storage Building (TRA-640) currently has a wet (glycol and water) fire sprinkler system that no longer meets National Fire Protection Association (NFPA) requirements [NFPA 13(2013)]. The proposed project would remove the existing wet pipe riser/anti-freeze system along with the associated wiring and replace it with a new dry pipe sprinkler system. A dry pipe system (air) would be needed for this building because portions of the building are not heated and freeze protection is necessary.
