3rd Nuclear Power Station Visitor Center

The Maanshan Nuclear Power Plant is located near South Bay of Hengchun in the rural Pingtung County. The plant is Taiwan's third nuclear power plant and the total life expectancy is estimated to last for 60 years. The five sources of energy are Coal, Oil, Solar, Nuclear Fission and Wind. Coal is usually very cheap but when used for energy but produces very little energy and does incomplete combustion and thus emits green house gases. Oil is expensive but produces very little energy. Solar manufacturing is relatively expensive, it also reflects lots of heat back up and often result in fatal damages to Animals. Nuclear Fission is a pretty expensive and needs quite a large piece of land to store it's waste but Nuclear Fission produces the most energy among the 5. Wind also produces lots of energy but would endanger birds that fly past. In our perspective, we feel that Nuclear Fission is the most economical method as long as there is enough land to store its dangerous byproducts. The construction of nuclear plants have a much higher standard than other normal buildings, since it is much more dangerous to us for it to break than normal buildings. The foundation is laid down with materials such as lead as a measure to reduce radiation in case of emergencies.Then,other structures are laid down and materials that can reduce radiation such as lead, steel and concrete are used.The reactor is then carefully transported and lowered, installed , along with many other components. for the nuclear reactor, it many layers of protection, with final protection being a 120cm concrete+0.6cm lead wall. In the event of an earthquake, the walls of the nuclear power plant are strong and sturdy, and can withstand tectonic/ground accelerations of up to 2.943 ms^-2 (approx. 0.3g). As such, the facility will ensure that it will receive warnings in time so the operations can be shut down safely and ensure that no radioactive, harmful or dirty substances will be released to the environment due to any openings caused by the quake. Nuclear fission, or nuclear chain reaction, is the driving reason behind the possibility of nuclear power. The isotope used for the nuclear reaction is the classical U-235 reaction. U-235 will be hit by a neutron to form U-236, which will split due to it being unstable. As such, it decays into radioactive waste, while 3 neutrons are left behind for a larger chain reaction. However, every chain reaction has to be controlled, and as such, control rods are put in place to control the rate of the chain reaction. The largest drawback of nuclear energy is the highly radioactive waste produced. This waste releases alpha, beta, and gamma radiation. Alpha radiation can be blocked by almost any surface as it is carried by relatively heavy helium atom nuclei. Beta radiation is carried by protons, but can be blocked by surfaces such as skin. However, if an object emitting either type of radiation is ingested, it will become fatal quickly. Gamma radiation is more serious as it travels as a wave, which can only be stopped by serious measures such as those used in the reactors, which are 1.2m of heavily reinforced concrete with an additioncal lead wall lining it. There are many by-products of the reaction, including americium 241, which is used in smoke detectors, highly radiated water used to cool the reactors, which can be recycled many times, and plutonium, which is used as the triggering mechanism in nuclear weapons and highly priced on black markets. The unusable by-products are disposed of, best by burying them in extremely dry environments deep undergroud, such as disused salt mines. Additionally, less radioactive materials such as the equipment used during the construction and managing of the nuclear plant, including gloves, tools, and overalls are buried in shallower pits.
