Radioactive Nuclear

Radioactive Nuclear

Radioactive decay, also known as nuclear decay or radioactivity, is the process by which a nucleus of an unstable atom loses energy by emitting particles of ionizing radiation. A material that spontaneously emits this kind of radiation which includes the emission of energetic alpha particles, beta particles, and gamma rays is considered radioactive.

Nuclear chemistry is the subfield of chemistry dealing with radioactivity, nuclear processes and nuclear properties.

Nuclear Fission

Nuclear Fission

In nuclear physics and nuclear chemistry, nuclear fission is a nuclear reaction in which the nucleus of an atom splits into smaller parts (lighter nuclei), often producing free neutrons and photons (in the form of gamma rays), and releasing a tremendous amount of energy.

Shell and tube Heat Exchanger

U-tubes

Shell and tube heat exchanger is a class of heat exchanger designs. It is the most common type of heat exchanger in oil refineries and other large chemical processes, and is suited for higher-pressure applications.

Heat Exchanger System

Heat Exchanger Design

Heat exchanger is a piece of equipment built for efficient heat transfer from one medium to another. The media may be separated by a solid wall, so that they never mix, or they may be in direct contact.

Nuclear Power Switzerland

Nuclear Plan Switzerland

After over 20,000 protesters marched earlier this week in opposition of nuclear power, the Swiss government has decided to ditch plans to build any new nuclear reactors. The decision comes after Swiss Energy Minister Doris Leuthard suspended the approval of three new rectors, pending more in-depth safety reviews in light of the nuclear tragedy at the Fukushima Daiichi plant.

Solar Cells in Japan

Solar Cells Japan

In the wake of the Fukushima Daiichi nuclear power plant disaster, there has been a call for the country to move away from atomic power and towards the mainstream use of alternative energy. While a recent report stated that Japan would be best to harness wind power, Softbank, a Japanese telecom firm, has announced that it will invest in the construction of ten solar-power plants.

Process Radioactive Decay

Radioactive Decay

Radioactive decay is the process by which an atomic nucleus of an unstable atom loses energy by emitting ionizing particles (ionizing radiation). The emission is spontaneous, in that the atom decays without any interaction with another particle from outside the atom (i.e., without a nuclear reaction). Usually, radioactive decay happens due to a process confined to the nucleus of the unstable atom, but, on occasion (as with the different processes of electron capture and internal conversion), an inner electron of the radioactive atom is also necessary to the process.

Steam Generators Nuclear System

Object Steam Generators Nuclear

Steam generators are heat exchangers used to convert water into steam from heat produced in a nuclear reactor core. They are used in pressurized water reactors between the primary and secondary coolant loops.

Pressurized Water Reactors System

Pressurized Water Reactors System

Pressurized water reactors (PWRs) constitute a majority of all western nuclear power plants and are one of two types of light water reactor (LWR), the other type being boiling water reactors (BWRs). In a PWR the primary coolant (water) is pumped under high pressure to the reactor core where it is heated by the energy generated by the fission of atoms. The heated water then flows to a steam generator where it transfers its thermal energy to a secondary system where steam is generated and flows to turbines which, in turn, spins an electric generator. In contrast to a boiling water reactor, pressure in the primary coolant loop prevents the water from boiling within the reactor. All LWRs use ordinary light water as both coolant and neutron moderator.
