< p> Manhattan Plan was the first U.S. nuclear weapons development program during World War II. The project lasted from 1942 to 1946 and involved many famous scientists from all over the world. Scientists have carried out a series of extremely complex experiments to improve the stability of plutonium cores in nuclear bombs. In Los Alamos laboratory, plutonium core tests resulted in the death of two important researchers, and other unknown injuries were countless, known in the scientific community as the "Devil Core".

"Devil Core" is a spherical plutonium core weighing 6.2 kg surrounded by tungsten carbide. Its function is to shield large amounts of nuclear radiation. The Trinity Test of "Devil Core" is the first nuclear explosion in human history. Only after the successful test did the atomic bombs explode in Hiroshima and Nagasaki.

Two fatalities occurred in the research experiment after "Devil Core". The first case of occurred on 21 August 1945. A researcher made a fatal mistake when testing the stability of the core. He accidentally placed an experimental device on the core, and the core suddenly exploded neutron radiation. The physicist died of radiation damage 25 days later. At the time of the accident, a security guard was also in the room, but the physicist dismantled the equipment in time to reduce radiation damage to others and save the lives of security guards. The second accident occurred on May 21, 1946. At that time, eight researchers tested the stability of the core. Physicist Louis Slotin lifted the protective shield of the core and inserted the screwdriver into the core. Previously, Slotin had done similar operations many times and was very familiar with this set of operations. This time, the tool slipped away from the core. Instantly, the plutonium core produced flashing blue light and huge radiation. Slotin felt sick then and vomited. Nine days later, Slotin died of acute radiation poisoning and complete destruction of the gastrointestinal tract. Other researchers were treated immediately, but fortunately it was okay.

In fact, a few months before Slotin's misleading accident, another surgeon, Robert Oppenheimer, objected to this test method of using a screwdriver and suggested that it be safer to operate with a robotic arm. But Slotin believed that he had tested many times and had rich experience, so it was no problem to use a screwdriver. He also said "It was just scratching on the tail of a dragon". After the accident, the Institute ordered that all plutonium core tests must use robotic arms, and that the experimenters must keep a certain distance from the plutonium core.
