Proposed Method to Predict Core Inventory history and Operator Time Margin during Small Break Accident

摘要: The blowdown history of the TMI-2 accident up to isolation relief valve associated with a small break LOCA is reviewed briefly. An analysis made determine what instruments should be added in core order prevent damage case accident. With procedure presented on how predict uncovered level and calculate operator time margin. Sample calculations are done for Finally, map show margin drawn measurable parameters by above methods.
