What is the name for an intermittent hot spring, characterised by violent explosive eruptions of steam and boiling water, alternating with quiet periods?
Botryoidal Spring is totally quiet. An eruption starts with no warning, most beginning with a blue bubble caused by immense steam bubbles forming below. Botryoidal Spring Botryoidal Spring is a geyser in the Lower Geyser Basin of Yellowstone National Park in the United States. Botryoidal Spring is part of the White Creek Group which includes A-0 Geyser and Spindle Geyser. As its name indicates, Botryoidal Spring was originally a hot spring (and botryoidal means 'bubbly'). In 1996, seismic activity caused to change from a sparkling spring into an explosive geyser. It erupts for a duration of about one minute with an interval
Boiling water reactor Boiling water reactor The boiling water reactor (BWR) is a type of light water nuclear reactor used for the generation of electrical power. It is the second most common type of electricity-generating nuclear reactor after the pressurized water reactor (PWR), also a type of light water nuclear reactor. The main difference between a BWR and PWR is that in a BWR, the reactor core heats water, which turns to steam and then drives a steam turbine. In a PWR, the reactor core heats water, which does not boil. This hot water then exchanges heat with a lower pressure water system,
