Nuclear explosion preventer

The van der Waals interaction between two nonbonded atoms i and j is described by Eq. (A.l)  

The second equation comes into use at very short distances to prevent two atoms from getting too close and mathematically fusing. 

The QCPE was originally formed, as its name implies, to distribute to potential users computer programs that had to do with quantum mechanical calculations. The scope of the distribution later expanded to include the entire area that subsequently became known as computational chemistry. The driving force behind the formation of this organization was a theoretician at Indiana University, in Bloomington, Indiana, named Harrison ShuU. The QCPE formally came into existence in April of 1962. A detailed article about the organization was published in 1999 by Boyd and Lipkowitz.

Chapter 4 described methods for limiting the time of exposure to weapons of mass destruction that utilize no explosives (e.g., aerosol delivery) or use of conventional explosives (e.g., dirty bomb). The basic procedure is to leave the contaminated area as quickly as possible, enter a nearby building to shelter against airborne contamination, remove soiled articles of clothing, and wash all exposed body parts (including the mouth and hair) as soon as possible. In Chapter 4, the time factor is applied primarily to limit the chances of potential future health effects. In this section, the time factor is applied after a nuclear explosion to prevent serious bodily harm and death. 

The proliferation of nuclear weapons would seriously increase the danger of nuclear war. Every effort should be made to implement the Treaty in all its aspects to prevent the proliferation of nuclear weapons and other nuclear explosive devices, without hampering the peaceful uses of nuclear energy by States parties to the Treaty. 

Under Article I (Basic Obligations) 1. Each State party undertakes not to carry out any nuclear weapon test explosion or any other nuclear explosion, and to prohibit and prevent any such nuclear explosion at any place under its jurisdiction or control. 2. Each State party undertakes, furthermore, to refrain from causing, encouraging, or in any way participating in the carrying out of any nuclear weapon test explosion or any other nuclear explosion. ... 

Iodine has as many as 37 isotopes, many of which happen to be radioactive. Further to this, many of these isotopes form in the event of a nuclear explosion, and should they be released into the atmosphere it s advisable to take iodine supplements to prevent the natural iodine in the thyroid gland from being replaced by a radioactive type. This helps mitigate the risk of cancer forming in the thyroid gland.

Nuclear power plants in the United States are supposed to be designed well enough to prevent accidents as serious as the one at Chernobyl. Nevertheless, the Three Mile Island plant in Pennsylvania, an aerial view of which is shown in Figure 22-14Z). experienced a partial meltdown in 1979. This accident was caused by a malfunctioning coolant system. A small amount of radioactivity was released into the environment, but because there was no explosion, the extent of contamination was minimal. 

Because the isotope uranium-235 is fissionable, meaning that it produces free neutrons that cause other atoms to split, it generates enough free neutrons to make it unstable. When the unstable U-235 reaches a critical mass of a few pounds, it produces a self-sustaining fission chain reaction that results in a rapid explosion with tremendous energy and becomes a nuclear (atomic) bomb. The first nuclear bombs were made of uranium and plutonium. Today, both of these fuels are used in reactors to produce electrical power. Moderators (control rods) in nuclear power reactors absorb some of the neutrons, which prevents the mass...
