OSTI ID:6513474
The TMI-2 accident showed the need for better real-time knowledge of water level and coolant density in the core and downcomer. A gamma-ray hodoscope at a light-water reactor could consist of about 24 identical collimated detector modules vertically arranged in the air gap or biological shield outside the pressure vessel. Ten detectors at 120 cm vertical intervals would cover the full water height of a PWR. (DLC)
