These failures resulted majorly from the challenging operating environments throughout the plant, after the Tsunami. • The fact that the roles and responsibilities within the onsite emergency response center and between the onsite and headquarters’ emergency response centers were unclear, may have contributed to the delays in the response from the officials. • Losing almost all the onsite AC/DC power at the plant, with the consequent loss of the real-time information to monitor some critical thermodynamic aspects of the reactors, containments and spent fuel pools significantly narrowed the ways to respond to the accident. • Flooding of the equipment and the absence of power generation caused the first three units to isolate from their heat sink, the Pacific Ocean, which led to overheating for a period of time, which eventually led to melt-down. • Although IAEA warned the plant of Japan’s proneness to Earthquakes of severe magnitude and the aftermath of these earthquakes, the plant officials did not take proper

Summary Of Wormwood Forest By Mary Mycio

382 Words | 2 Pages

In chapter four of the novel Wormwood Forest by Mary Mycio, Mycio explains the aftermath of the Chernobyl nuclear reaction, and how it had changed the ecosystem drastically.

This power plant had a sudden power surge in its reactor Unit 4, which resulted in a devastating incident. This caused large amounts of radioactive materials to be released into the air, and causing a level seven nuclear disaster, the highest level possible. After reading this chapter, it made me consider the bombs dropped on Nagasaki and Hiroshima 70 years ago, and the level seven nuclear disaster in Fukushima, Japan.
