Therefore, steam leakage takes place through the main valve and regulating valve, seals and glands, spaces between nozzles and moving blades, spaces between the diaphragm and shaft of the turbine, and; spaces between moving blade rings and the turbine casing. Leakage of steam through these gaps is a direct loss of energy.
A leak appearing within an analytic region (a rule added to the camera) is immediately analyzed for its attributes, including thermal temperature, size, and behaviour (e.g. spraying, pooling, spilling). When a leak is determined to be valid based on set parameters, an alarm notification with leak video is generated and sent to a monitoring station.
Hot water and steam leaking from a broken pipe killed five workers and resulted in six others being injured. [ 1 ] [ 7 ] [ 8 ] The accident, rated at INES Level 0, had been called Japan's worst accident at a nuclear plant [ 9 ] [ 10 ] before the crisis at Fukushima I Nuclear Power Plant .
Tank leak detection is implemented to alert the operator to a suspected release from any part of a storage tank system, what enables to prevent from soil contamination and loss of product. In many countries regulated UST are required to have an approved leak detection method so that leaks are discovered quickly and the release is stopped in time.
The Reactor Protection System (RPS) is a system, computerized in later BWR models, that is designed to automatically, rapidly, and completely shut down and make safe the Nuclear Steam Supply System (NSSS – the reactor pressure vessel, pumps, and water/steam piping within the containment) if some event occurs that could result in the reactor entering an unsafe operating condition.
