Nuclear Chemistry Project

The Chernobyl Nuclear Power Plant is a decommissioned nuclear power station near the city of Pripyat, Ukraine, 14.5 km northwest of the city of Chernobyl, 16 km from the Ukraine–Belarus border, and about 110 km north of Kiev. Reactor No. 4 was the site of the Chernobyl disaster in 1986 and the power plant is now within a large restricted area known as the Chernobyl Exclusion Zone.

Chernobyl Nuclear Power Plant

1. The Chernobyl reactor complex just 80 miles north of Kiev, Ukraine is made up of four Russian made RBMK-1000 water-cooled graphite moderated reactor designed to make plutonium for nuclear weapons and modified to also produce electricity. 2. There is roughly a 36 mile diameter "dead zone" surrounding the reactors from which over 160,000 people were evacuated, permanently abandoning over 600 years of continuous habitation and culture around the towns of Chernobyl and Pripyat. Numerous "hot spots" of radioactive contamination persist far beyond a "zone of alienation;" many areas continue to emit radioactivity at levels ranging from 40 to 100 curies/kilometer2. As many as 150,000 people were dislocated in Belarus and 75,000 in the Russian Federation.3. Wind and water continue to spread Chernobyl's deadly radioactive contamination over even wider areas. Ground water flowing under the damaged Chernobyl reactor is spreading an underground radioactive plume into the Pripyat and Dnieper Rivers, threatening the city of Kiev's water supply. 4. The Ukrainian government estimates 8000 people have died in their country from the nuclear accident as a result of radiation-related illness.

The Ukrainian Ministry of Health places that figure at 125,000 with disease rates, miscarriages and birth defects steadily rising. Officials in Belarus estimate that roughly 2 million have suffered in some way as a result of the nuclear meltdown. Birth rates have fallen 50% in Belarus. Over 3 million Russians were exposed to the radioactive fallout in 1986. 4.

Any U.S. nuclear reactor could have an accident resulting in a catastrophic release of radiation to the American public with similar or worse consequences as evidenced by Chernobyl.

Radioactivity: the emission of ionizing radiation or particles caused by the spontaneous disintegration of atomic nuclei.•radioactive substances, or the radiation emitted by these.

Alpha Particle: Consist of two protons and two neutrons bound together into a particle identical to a helium nucleus. They are generally produced in the process of alpha decay, but may also be produced in other ways.

Beta Particle: Beta particles are high-energy, high-speed electrons or positrons emitted by certain types of radioactive nuclei.

Gamma Rays: Refers to electromagnetic radiation of extremely high frequency and therefore high energy per photon. Gamma rays are ionizing radiation, and are thus biologically hazardous. They are classically produced by the decay from high energy states of atomic nuclei.

Mass Number: Is the total number of protons and neutrons in an atomic nucleus. Atomic Number: Is the number of protons found in the nucleus of an atom of that element, and therefore identical to the charge number of the nucleus.Isotope: Is the number of protons found in the nucleus of an atom of that element, and therefore identical to the charge number of the nucleus.

Radioactive Decay: The process by which a nucleus of an unstable atom loses energy by emitting ionizing radiation. A material that spontaneously emits this kind of radiation which includes the emission of alpha particles, beta particles, and gamma rays is considered radioactive.Examples:-Alpha Decay-Beta Decay-Gamma Decay

Nuclear Fission: Is a nuclear reaction or a radioactive decay process in which the nucleus of an atom splits into smaller parts. The fission process often produces free neutrons and photons, and releases a very large amount of energy even by the energetic standards of radioactive decay.Nuclear Fusion: Is a nuclear reaction in which two or more atomic nuclei collide at a very high speed and join to form a new type of atomic nucleus. During this process, matter is not conserved because some of the matter of the fusing nuclei is converted to photons. Fusion is the process that powers active or "main sequence" stars.
