Void coefficient reactor is reduced. In boiling-water reactors with large negative void coefficients, a sudden pressure rise (caused, for example, by unplanned closure of a steamline valve) will result in a sudden decrease in void content: the increased pressure will cause some of the steam bubbles to condense ("collapse"); and the thermal output will possibly increase until it is terminated by safety systems, by increased void formation due to the higher power, or, possibly, by system or component failures that relieve pressure, causing void content to increase and power to decrease. Boiling water reactors are all designed (and required) to handle this
Collapse into Now ways, but still capable of quietly insinuating surprises. All songs written by Peter Buck, Mike Mills and Michael Stipe, except as noted. Collapse into Now Collapse into Now is the 15th and final studio album by the American alternative rock band R.E.M., released on March 7, 2011, on Warner Bros.
