“…Regarding the six observers, Hempelman et al (1979) mentioned that they were exposed to lower levels of radiation, and thus there were no major impacts on their health. Malenfant (1996) indicated that this accident, as well as similar accidents to Slotin's, have a great significance because they provide information about the undesirable effects when potentially hazardous experiments were conducted without the appropriate planning, preparation and safety measures. In other words, Slotin's accidents and similar accidents of the past provided us with the knowledge that nuclear energy can be hazardous and disastrous if used without respect for safety measures.…”

“…Based on McLaughlin et al (2000), two of the members, Louis Slotin and Alvin Graves, were directly involved in the experiment, while the other six individuals were observing the demonstration. Malenfant (1996), who reported four similar laboratory accidents between 1945 and 1946, reported detailed information regarding the LA-1 accident during Slotin's demonstration, and mentioned that the eight personnel were exposed to excessive levels of radiation. More specifically, Oettingen (2018) underlined that Slotin was exposed to 2100 rem, leading to his death nine days after the occurrence of the accident, while Graves received 360 rem, and recovered several weeks after the experiment.…”

This paper reviews the case of nuclear energy. Currently, the worldworld is facing one of the greatest energy crises due to the Russo-Ukrainian war. This conflict has lead to limited sources of gas, causing a dramatic decrease in energy supply, leading to emerging energy crisis risks. This is one on the main purposes of reviewing nuclear energy as a possible energy alternative in the future. Apart from presenting the basis of nuclear energy and nuclear reactors, we attempt to compare this source of electricity with other renewable energy forms, such as solar, wind and hydroelectric power. Furthermore, we illustrate the benefits and drawbacks that have been observed regarding nuclear power as well as its contribution to economic growth and the impact it has had on the environment. It has been said that, with the use of nuclear power, air pollution will be reduced because of the elimination of greenhouse gases. However, nuclear power, apart from the final product, generates waste that in this case is radioactive, meaning that the management and disposal techniques are of the utmost importance. Of course, unfortunate events that involved nuclear power do exist and are unfortunately engraved in our memories. Both the nuclear accidents, such as Three Mile Island, Chernobyl and Fukushima, and nuclear weapons usage by military forces, the well-known atomic bombing of Hiroshima and Nagasaki, bring great controversy regarding the adaptation of nuclear power. As is presented in the paper, since the beginning of the new millennium the scheme of energy production and electricity production appears to have changed drastically. By using available data reported by BR, we illustrated that the production of energy and electricity has increased over the last 22 years (2000–2021) due to excessive demand; however, what is more important to mention is the share of both electricity and energy derived from renewable forms such as solar, wind and hydroelectric power. It is shown that more and more countries adopt those sources of energy than did in previous decades. It is crucial to note that it is not the science that causes catastrophic events, but rather the errors of humans.
