“Fire Detection and Response Time at the Solid Waste Management Facility at the Savannah River Site” – “Staff Issue Report” linked here
“Conclusion. The Board’s staff review team concluded that SWMF cannot adequately protect the assumption of a two-hour fire department response. There are no automatic fire detection systems throughout most of the facility, and it is only staffed Monday through Thursday during normal work hours, nominally from 0500 to 1700. Therefore, it is possible for a fire to burn undetected and exceed the two-hour response time assumption. Facilitated by the use of combustible pallets and the presence of high-curie containers outside of overpacks, a fire event that exceeds two hours has the capability to affect more MAR than is currently assumed and analyzed in the SWMF accident analysis. This could result in a higher dose consequence than what is documented in the safety basis.”
