This research paper discusses the Three Mile Island incident to include what started it, the results in the aftermath, and how it could have been prevented. The Three Mile Island Unit 2 (TMI-2) reactor, near Middletown, Pa., partially melted down on March 28, 1979. This was the most serious accident in U.S. commercial nuclear power plant operating history, although its small radioactive releases had no detectable health effects on plant workers or the public. Its aftermath brought about sweeping changes involving emergency response planning, reactor operator training, human factors engineering, radiation protection, and many other areas of nuclear power plant operations. It also caused the NRC (Nuclear Regulatory Commission) to tighten and …show more content…
New equipment updates can resolve design related issues that come from the original build, and can also lead into more efficient and properly functioning equipment. An analogy which explains this follows: The Nuclear Regulatory Commission mandates that equipment with low level radiation in the US Army’s radiological safety program must post an NRC 3 form on the outside of the storage areas. This lead into the Army fielding new radiological detection devices that no longer contain ionizing radiation. The AN-VDR2 Radiac Meter was replaced with the AN-UDR 13 due to the AN-VDR-2’s low level Thorium 232 ionizing radiation detection source. With the AN-UDR 13’s updated design, ionizing radiation is not a problem that if damaged would release radiation into the environment.
Human Factors
Proper training and protocols may have solved or prevented the problem. With more problems to add to the list of chain reactions from the accident, the government had to change industry safety which in turn, increased industry safety. New study groups were used to research the incident. New organizations had to be created to conduct proper training implementing the safety measures for the power plant operators. Many new publications had to be brought into existence to have better oversight of nuclear power plant operations. A
