White Hat asks Ponytail for an explanation of how the meltdown occurred, but his understanding of science is so limited that he finds even the first part of the first sentence of Ponytail's explanation too complicated to understand. |

+ | Ponytail starts explaining the role of the graphite in the reactor's core as the neutron moderator, but White Hat immediately interrupts her, as if he doesn't understand the word ''graphite''. Ponytails tries starting the explanation from another angle, stating that the nuclear reactor was inadvertently put in an unstable state moments before the disaster, but White Hat interrupts again. Realizing that White Hat does not understand scientific terms of ''graphite'' and ''reactor'', Ponytails resolves to use plain words every person should know, and to employ a metaphor. | ||
She compares the purpose of a nuclear reactor as a heat-generating device to primitive humans' way of heating by starting a fire. She goes on describing how a fire can be started by banging rocks (pieces of flint) to create sparks, which in turn would light a fire. Seeing that White Hat understands this simple activity, she compares starting a runaway nuclear fission reaction to banging rocks too hard, presumably splitting or crushing them and injuring the wielder. | She compares the purpose of a nuclear reactor as a heat-generating device to primitive humans' way of heating by starting a fire.

− | Nuclear reactions are often simplistically described and illustratively pictured as forcibly colliding colored balls representing various nuclear particles or nuclei, resulting in creating other balls, joining some into bigger ones, or splitting some into smaller ones.

Fission reaction, in particular, involves a neutron causing a heavy nucleus to split into smaller parts, including more neutrons. To facilitate nuclear reactions, particles need to carry great amounts of energy as compared to their tiny sizes and masses. This may evoke a mental image of hitting rocks too hard so they split. |

To sustain a controlled nuclear fission chain reaction, various mechanisms are involved in controlling the level of neutrons produced and consumed by the nuclear fuel. Due to various design flaws and operation errors leading up to the Chernobyl disaster, the reactor core was producing less heat than desired by the reactor operators, who are preparing to conduct a simulated power outage experiment. To increase heat production, the operators pulled out almost all available controlling rods, akin to turning the volume knob to max on a muted sound system. Then the commencement of the experiment, which reduced the coolant water supply, further enhanced the positive feedback loop of the neutron production. Seeing a rapid rise in the power output, the operators hit the emergency shutdown button. A critical design flaw of the reactor caused the neutron production to temporarily increase in the reactor once the emergency shutdown button is pressed in this condition, which resulted in an explosion caused by the multiple positive feedback loops taking place. Per the title text, this is analogous to unmuting a sound system that has the volume turned all the way up, creating the "deafening blast of sound". |
