State-of-the-ART for Liquid-Level Measurements Applied to in-Vessel Coolant Level for Nuclear Reactors

摘要

The TMI-2 accident indicated that a direct indication of the liquid level in the reactor vessel would have told the operators that the core was being uncovered. This state-of-the-cost survey covered the following methods: heated thermocouple, differential pressure, ultrasonic, capacitance, microwave, time-domain reflectometry, and externally mounted radiation detectors.
