Submarines: The Revolutionary And Civil Wars

Nuclear power plants use heat created by nuclear reactions to heat water and create steam which turn turbines to produce power.

Nuclear energy is defined as energy released by reactions within atomic nuclei, as in nuclear fission or fusion (“Dictionary”). Nuclear fission is defined as a nuclear reaction in which a massive nucleus splits into smaller nuclei with the simultaneous release of energy. The definition of nuclear fission is as reaction in which two nuclei combine to form a nucleus with the release of energy (“Dictionary”). The process of nuclear fission and fusion happen inside of a nuclear reactor that is located in a nuclear power plant. Also needing to be defined, a nuclear reactor is a device in which nuclear fission initiates a controlled chain reaction, producing heat energy typically used for power generation, and neutrons and fission products (“Dictionary”). It is also important to know that there are a few different kinds of nuclear reactors. The different kind of reactors include: pressurized water reactors, boiling water reactors, gas-cooled reactors, and light water graphite reactors (Blau 117). Finally, a nuclear power plant is a facility for the production of electricity using

A submarine is defined as “something that functions or operates underwater; specifically: a naval vessel designed to operate underwater.” This definition holds true today but started at the beginning of the Civil War when submarines originally became a popular choice of weaponry. In general, submarine crews were composed of a commander, who steered the boat, and six or more men who used hand cranks to move the boat. Many inventors intended on creating electric motors to move the boat, but they were unable to produce enough torque. Submarines were primarily used in combat because they could travel invisibly. Innovations like submarines did not just change the way people fought wars–they also changed the way people lived.

In nuclear fission, atoms of uranium-235(any unstable nucleus with a sufficiently high number of nuclear mass) are bombarded with neutrons. Ordinarily neutrons move too

This powers generators. Fission also splits atom nuclei into small atoms but only big atoms like uranium and plutonium. The isotopes of these atoms really help for example uranium 235 and plutonium 239. They both have large nuclei when split. This will then cause it to release a lot of energy during this process, the more nuclei the more reaction there will be. This is also the process that power station use as well for chain

When a uranium nucleus splits, energy is released (as steam). This steam turns generators and creates electric energy. One pro is that nuclear fission does not release as many pollutants as fossil fuels. Two cons are that it nuclear waste is hard to dispose of and also can be harmful for humans.

Nuclear energy is gathered by the process of splitting uranium atoms. By splitting these atoms, there is some mass loss, and this mass can then be used as energy. This process is called fission. The heat from this fission is used to turn water into steam, and this steam turns the turbine generator in a reactor, which produces energy. Nuclear power plants have many advantages when compared to other renewable energy sources.

1b/process. “How do we harvest this lost energy,” you might be wondering? Well, nuclear energy receives its power from the fission, or splitting, of atoms in very dense radioactive metals. Once one atom is split, the halves separate into 2 or more less dense atoms, and remaining neutrons can be shot out at high velocities. If these neutrons slam into another atom and are captured by it, that atom has a chance that it too will undergo fission. This cycle of splitting atoms is a chain reaction. Nuclear fission requires power to start the chain reaction, and it needs a certain amount of Uranium, called a critical mass, before this chain reaction can support itself and create excess energy. This excess energy is released as heat, usually into water. This changes the water into steam and is used to turn turbines to produce electricity. According to an article written by the U.S. Dept. of Energy, the first successful attempt at a self-sustaining nuclear reactor was on December 2nd, 1942.

I do agree with you. Submarines were the silent weapon of the Navy. With he high risk of casualties they were an underwater, killing machine making the difference in a battle. A new strategy was in place when Commander Dudley ‘Mush’ Morton takes a position on 12 December 1942. Aboard in the USS Wahoo he orders to patrol the submarine in sea level monitoring of activity in the sky for enemy airplanes. Morton was acquiring information about Japanese movement in the area. Moreover, he makes a record of sinking five enemy vessels in one patrol. Morton was awarded navy’s second-highest combat decoration for his actions, and the Wahoo awarded a Presidential Unit Citation. Morton actions on command were not always correct. He ordered to kill Japanese

Torpedoes can easily be considered one of the most significant modern inventions in maritime history leading up to the advancements made during the late 1800s. The earliest torpedoes in today's terms would be considered mines, as they were not self propelled, and existed in the early 1800s. Adaptations of early sedentary torpedoes were used widely during the American Civil War, although their significance in naval warfare was overshadowed by the emergence of steam engines and iron armor on ships. Post Civil War, many advancements were made regarding rifling that led to the invention of the self propelled torpedo. In World War I and World War II, torpedoes were the weapon of choice in naval engagements. Torpedoes continued to be a threat

Submarines require a great deal of energy in order to propel itself while out at sea, energy which is generally provided by a reactor. The

"Nuclear submarines use nuclear reactors, steam turbine, and reduction gearing to drive the main propeller"(Works). All old submarines used snorkels so they where very close to the surface of the ocean so they were very vulnerable to airplane attacks "Some have batteries to make them run off electric power but they have to be charged using either diesel or a nuclear reactor"(Works). Nuclear submarines have a advantage because nuclear submarines can be submerged for weeks or months on end and not have to surface. Another thing is that nuclear fuel lasts much longer that diesel fuel so they can stay at sea and not have to port for fuel (Works). Diesel engines can only work when surfaced or use a snorkel so the engine can breath. The Diesel engine submarines just surface to get the batteries charged than go back below the

The side propellers would then be set in motion, allowing the submarine to sink to a required depth. The great thing about this boat is that, should there be a failure of the engine, the boat, from its own buoyancy, would rise to the surface.

A submarine is a watercraft that is capable of independent operation under the sea. Submarines do not require support ships because submarines can renew their air and power supplies independently. Submersibles also submerge and operate underwater, but they need the support of a larger vessel. Submersibles cannot renew their air and power supplies without support. For this reason submersibles are usually smaller and cannot spend as much time underwater as submarines.

In order for the bomb to occur the subcritical masses must be brought together to form a supercritical mass, this provides enough neutrons to create and maintain a fission reaction. This is done through a neutron generator. This is a generator containing a small pellet of beryllium and polonium which are separated by foil within the fissionable fuel core.
