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 Knight of the Word that lead her to this truth. John realizes that he's been subtly led toward the Void ever since Stefanie came into his life, after San Sobel; as a shape-shifting demon, Stefanie forged documents to support the embezzlement accusations, attacked Nest and her friends in the park, set fire to the shelter to explain the wounds she'd sustained trying to kill Nest, lied about John being fired, and morphed into Simon at the museum so John would be tricked into killing the real, innocent Simon and completing his turn to the Void. Finally, John confronts Stefanie at his apartment. She does
