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
The Heart Is a Lonely Hunter (Once Upon a Time) that Graham helped fill a void for her character, commenting that his loss "was not easy for [Regina]. That’s why, when she crushes his heart, there’s a tear coming out of her eye. She didn’t want to do it, but she had no choice — almost like how she had no choice to kill her father. I’m not saying I agree with it, but for the character, it’s what she had to do." Parrilla also cited "The Heart Is a Lonely Hunter" as the first episode where viewers see "how the two worlds collided," a reference to Regina's ability to
