A comparison of two criticality accident alarm system detector locations for the X-700 building at the Portsmouth Gaseous Diffusion Plant. Final report

By C.W. Skapik and B.L. Jr. Lee


A previous analysis of the X-700 Building Criticality Accident Alarm System (CAAS) showed that some of the building may not adequately be covered by the one building CAAS detector in its current location. This report compares the results of that analysis with a new analysis where the detector is in a different location. The new detector location (outside of the storage area in the center of the building--near column B-7) showed coverage for all points previously analyzed. The new centralized detector location reduces the distance and shielding between the source points and the detector. This explains the difference in the level of response when compared to the original (actual) detector location in the new annex west of the building
