Nuclear Power Sources For Space Exploration

The United States needs a change in its energy sources. Oil, first of all, is a scarce resource that will eventually run out, and it also makes the U.S. depend on the political situation in other countries, as can be seen at the frequent changes in oil prices due to the political situation in the Middle-East. Alternative energy sources are an important issue to consider and nuclear energy is certainly the most controversial. There are currently 104 nuclear power plants operating in the United States, but the licenses of those plants will expire in foreseeable future, the first one already in 2013 and the last one in 2046 (Nuclear Energy Inst.). Those expiration dates initiate the discussions if the licenses should be renewed for the plants

The United States should use nuclear energy to help supplement energy demand because it’s cost-effective, safer for the environment, and a more reliable source of energy than any of the other types of fuel. Some of the topics of interest are cost-effectiveness, recycling options, long term storage options, environmental protection technologies currently being used, and a breakdown of how nuclear energy out performs other sources of power year round.

Summary: In this paper I will discuss the overall of nuclear energy to rectify some misconception. I will give the advantages and disadvantages for using nuclear energy and let the readers understand the basic idea of it.

However, before heading towards a nuclear future, we have to learn the basics - these two nuclear reactions. This teaching document will only explain the basic nuclear fusion and nuclear fission process description. Some technical jargon will be explained before the process description. There will be an introduction to some of the types of subatomic particles, some talk about the nuclear fusion mechanism, and a general description for the chain reaction.

Another nuclear technological advance in the US military is the nuclear aircraft carrier.The aircraft carrier is the heart of the US Navy.By adding nuclear technology to these massive giants of the sea, it only makes the Navy’s heart beat stronger.The main power sources of a nuclear aircraft carrier are two GE pressurized water reactors, which power four turbines.[4]Like the nuclear powered submarine, nuclear reactors are the main source of energy for the carriers.Also, having a nuclear reactor as a main source of energy enables the carriers to sail all over the world for many years without having to constantly refuel.[5]Having nuclear power aircraft carriers in its arsenal allows the US to virtually have multiple floating bases anywhere in the world at one time.The nuclear reactor also allows the carrier to reach its destination sooner, possibly preventing an outbreak of conflict or seeing to a rapid conclusion of a conflict.[6]

Nuclear power is useful for the submarine fleet and nuclear icebreakers. The use of atomic engines allows them to exist for a long time autonomously, move to any distance. For submarines - to be under water for months.

Throughout history, the source of energy that powers the world has advanced alongside technology. The power on which civilization thrives has to be in accordance to the demand at which it is required. As technology evolves, objects from which energy can be extracted can expanded exponentially. In the status quo, the United States is trying to limit the greenhouse gas emissions instead of just switching power sources which is the wrong direction they should be going in. [Thesis] Instead of wasting their time and money investing in burning coal as their main source of power, countries and their governments need to assist in the transition to a more cost effective and efficient form of energy in the form of nuclear energy.

Nuclear energy was likewise discovered to be useful in naval tactics and in sourcing electricity. As technology has significantly advanced and knowledge has expanded beyond measures, the realm of nuclear engineering has indeed achieved scientific milestones. In practice of modern times, nuclear energy is manufactured within power plants, capable of supporting an outstanding amount of electricity (World Nuclear Association). However, this limited method of energy production is thought to be dangerous. Nuclear engineering is certainly one complex subject and is foreign to the majority of the world population. Within a nuclear power plant, reactors are employed to force uranium ions to undergo the process of nuclear fission; nuclear fission is the separation of atoms, the smallest unit of matter. This splitting of uranium ions releases energy, thus, producing usable heat. Heat is crucial to not only nuclear energy production; rather, heat is necessary in all power plants. Such will then become the steam that gyrates turbines. These turbines are coupled with electromagnets which, finally, yield electricity (How Nuclear Reactors Work). One foremost flaw of nuclear power is the consequential radioactive waste that must be monitored for a long while following disposal. Nevertheless, as resources upon this planet are surely depleting, original forms of energy production are mandatory. In consideration of such, nuclear power plants have proved to be both efficient

Nuclear power is achieved through fission; the splitting of an atom. Usually, the atom is uranium, the ninety-second element on the periodic table. One of the heavier elements, uranium is unstable and produces an extreme amount of energy when split (Reynoldson 5). Other elements like plutonium can also be used, but plutonium is very rare which results in the majority of nuclear

Nuclear technology can make deep space exploration possible while making daily life on Earth more comfortable and safer. Nuclear power has minimal threats to our natural environment, and nuclear science can detect and cure many diseases. Seeing all the possibilities related to nuclear engineering, I am easily drawn into this field.

Nuclear power produces huge amount of energy through nuclear fission. 1 ton of uranium fuel, which is used as a fuel in generating electricity, equals to 50,000 tons of fossil fuels for generating the same amount of electricity. Since a small amount of nuclear fuel can produce a large amount of energy, it is powerful and efficient.

It is estimated that at today’s rate of consumption, the earth has about fifty years left of fossil fuels. In contrast, due to the very small amount of uranium needed to create a huge amount of energy, the supply of nuclear energy is almost infinite [Jiskha].

The world as we know today is dependent on energy. The options we have currently enable us to produce energy economically but at a cost to the environment. As fossil fuel source will be diminishing over time, other alternatives will be needed. An alternative that is presently utilized is nuclear energy. Nuclear energy is currently the most efficacious energy source. Every time the word ‘nuclear’ is mentioned, the first thought that people have is the devastating effects of nuclear energy. Granting it does come with its drawbacks; this form of energy emits far less pollution than conventional power plants. Even though certain disadvantages of nuclear energy are devastating, the advantages contain even greater rewards.

Many military and some civilian (such as some icebreaker) ships use nuclear marine propulsion, a form of nuclear propulsion. A few space vehicles have been launched using full-fledged nuclear reactors: the Soviet RORSAT series and the American SNAP-10A.

Nuclear energy is an alternative source of energy that holds great amounts of energy and is one of the future sources of energy for this world. “Nuclear energy is energy in the nucleus (core) of an atom. There is enormous energy in the bonds that hold the nucleus together. Energy is released when those bonds are broken” (Uranium). Unlike a chemical reaction with fossil fuels, nuclear reactions create an even greater amount of energy than fossil fuels. “Nuclear energy can be used to make electricity, but first it must be released it can be released from atoms in two ways: nuclear fusion and nuclear fission” (Uranium). Nuclear energy already provides 1/5 of all the energy in the U.S.,
