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
A Void constraint to the original, avoiding the most commonly used letter of the alphabet. This precludes the use of words normally considered essential such as "je" ("I"), "et" ("and") and "le" (masculine "the") in French, as well as "me," "be," and "the" in English. The Spanish version contains no "a", which is the second most commonly used letter in the Spanish language (first being "e"), while the Russian version contains no о. The Japanese version does not use い ("i") at all. "A Void"'s plot follows a group of individuals looking for a missing companion, Anton Vowl. It is in part
