Gmod Nuclear Power Plant
Tsar Bomba (RDS-220 hydrogen bomb) – 50MtThe RDS-220 hydrogen bomb, also known as the Tsar Bomba, is the biggest and most powerful thermo nuclear bomb ever made. It was exploded by the Soviet Union on 30 October 1961 over Novaya Zemlya Island in the Russian Arctic Sea.The hydrogen bomb was air dropped by a Tu-95 bomber using huge fall-retardation parachute. The detonation occurred 4km above the ground producing a yield of 50Mt, which is believed to be equivalent to the explosive power from the simultaneous detonation of 3,800 Hiroshima bombs.Tsar Bomba contained three stages, unlike normal thermonuclear weapons that explode in just two stages.
While the addition of third stage increased the explosive power of the thermonuclear, the bomb’s actual yield of 100Mt was reduced by 50% to limit radioactive dust. The development of Mk-41 commenced in 1955 to fulfil the US Air Force’s requirements for a Class B (10,000lb), high yield thermonuclear weapon.
The prototypes were test fired during Operation Hardtack Phase I in 1958.The three-stage thermonuclear weapon was primarily boosted by deuterium-tritium and believed to have used Lithium-6 (95% enrichment) deuteride fuel for fusion stages. Two versions were produced, a 'clean' version (lead encased third stage) and 'dirty' (uranium encased) version, both were air dropped by attaching with two parachutes for delayed detonation.TX-21 'Shrimp' (Castle Bravo) – 14.8MtThe TX-21 'Shrimp' thermonuclear weapon was exploded by the US on 1 March 1954 during its biggest ever nuclear weapon test, Castle Bravo, at Bikini Atoll in the Marshall Islands. The detonation yielded an explosion force of 14.8Mt.The TX-21 was also a scaled down variant of the TX-17 thermonuclear weapon first tested during the Castle Romeo exercise in 1954, and used lithium deuteride fusion fuel.
The fuel for this two-stage hydrogen bomb consisted of 37% to 40% enriched Lithium-6 deuteride enclosed in a natural uranium tamper.The TX-21 was exploded 7ft above the surface and radioactive fallout spread over more than 11,000km2. The explosion dispersed radioactive substance over some parts of Asia, Australia, the US and Europe.Mk-17/EC-17 – 10Mt to 15MtThe Mk-17, weighing over 18t, was the heaviest thermonuclear nuclear weapon ever made by the US.
It was also the first operational hydrogen bomb of the US Air Force. The Mk-17 had an estimated yield of 10Mt to 15Mt.About 200 Mk-17 bombs were produced by 1955 and the bomb was retired from the USAF service in 1957. The large and heavy bomb had a loaded weight of 41,400lb.The bomb was air dropped by B-36 bombers using a single 64ft parachute to delay the fall so that the aircraft had additional time to escape from the detonation impact.MK 24/B-24 – 10Mt to 15MtThe Mk-24 thermonuclear bomb, which was one of the most powerful nuclear weapons built by the US, was designed based on the Yankee test device. Yankee was one of the six detonations in the Castle nuclear detonation test series. The Mk-24 was produced in a number of configurations with explosive force ranging from 10Mt to 15Mt.The MK-24 was similar in appearance to the Mk-17 thermonuclear bomb. The US produced 105 Mk-24s between 1954 and 1955.
The weapon was eventually retired from the USAF service in 1956.The deployed prototype of the Mk-24, designated as EC-24, was tested on 5 May 1954 during the Yankee test generating a yield of 13.5Mt.Ivy Mike H-Bomb – 10.4MtThe Ivy Mike hydrogen bomb was based on the thermonuclear device demonstrated during the Test George conducted by the US on 9 May 1951 as part of Operation Greenhouse series of four nuclear device detonation tests. The Ivy Mike test yielded an explosion of 10.4Mt, 700 times the explosive force of the weapon dropped on Hiroshima.The device had a length of 6m and diameter of 2m and weighed 82t. It was not a deliverable weapon and was only used to validate the concepts of nuclear weapons. A simplified and lighter variant, known as the EC-16, was developed later.The nuclear weapon employed an implosion device similar to that of 'Fat Man' bomb, which exploded over Nagasaki, to activate the cooled liquid deuterium.Mk-36 nuclear bomb – 10MtThe Mk-36 was a two-stage thermonuclear bomb used a multi-stage fusion to generate explosive force of up to 10Mt. Two versions, Y1 and Y2, were produced.The Mk-36 was an upgraded variant of the Mark 21 which itself was a weaponised derivative of the 'Shrimp' device.
The US produced 940 Mk-36 bombs during 1956-1958 and converted 275 bombs into Mk-21s.The Mk-36 was designed to be airdropped using two parachutes. All Mk36 nuclear bombs were retired by 1962 and replaced by B41 nuclear bombs.B53 (Mk-53) – 9MtThe B53/Mk-53 was the oldest and one of the highest yield nuclear bombs in the US inventory. The weapon had an estimated yield of 9Mt and was retired from the USAF service in 1997. It was deployed aboard B-47, B-52 and B-58 bombers.The B53 nuclear bomb was a two-stage implosion weapon using highly enriched uranium and 95% enriched Lithium-6 deuteride fusion fuel. It was produced in two versions including B53-Y1 and B53-Y2.The nuclear weapon was designed to be air dropped using five parachutes, while the free fall delivery was also possible by jettisoning the 'can' with the parachutes.Mk-16 (TX-16/EC-16) nuclear bomb – 7MtThe Mk-16 hydrogen bomb was the only liquid fuel thermonuclear weapon ever built by the US. It was based on the Ivy Mike hydrogen bomb and had an estimated yield of up to 7MT.The Mk-16 was built in Experimental/Emergency Capability (EC) variants and initially completed a drop test in December 1953. The weapon was deployed in EC version designated as EC-16.The TX-16 bomb measured 61.4in in diameter and 296.7in in length.
The weapon retired from the service by April 1954 as it was replaced by solid-fuelled thermonuclear weapons such as TX-14 and Mk-17.Mk-14 / TX-14 – 6.9MtThe Mk-14, which was the first fielded solid-fuel thermonuclear weapon of the US, yielded 6.9Mt when it was exploded during the Castle Union nuclear test in April 1954. The bomb used a non radioactive isotope of lithium (Li-6) instead of tritium.The procurement for the TX-14 programme was approved in September 1952. The TX-14s in emergency-capability configuration were inducted into service in February 1954. The Mk-14s retired in October 1954 and some of them were recycled into the Mk-17 weapons by September 1956.B-36 and B-47 bombers were used to carry TX-14s, and the rate of fall was decelerated by employing the parachute drop method.
Flanked by, a nuclear reactor is contained inside a sphericalA nuclear power plant is a in which the heat source is a. As it is typical of thermal power stations, heat is used to generate steam that drives a connected to a that produces. As of 2014, the reports there are 450 nuclear power reactors in operation in 31 countries.Nuclear plants are usually considered to be stations since fuel is a small part of the cost of production and because they cannot be easily or quickly. Their operations and maintenance and fuel costs are, along with hydropower stations, at the low end of the spectrum and make them suitable as base-load power suppliers. The cost of spent fuel management, however, is somewhat uncertain.
Main article:Electricity was generated by a nuclear reactor for the first time ever on September 3, 1948, at the in, which was the first nuclear power station to power a light bulb. The second, larger experiment occurred on December 20, 1951, at the experimental station near.On June 27, 1954, the world's first nuclear power station to generate electricity for a, the, started operations in, the Soviet Union. The world's first full scale power station, in England, opened on October 17, 1956.
The world's first full scale power station solely devoted to electricity production—Calder Hall was also meant to produce plutonium—the —was connected to the grid on December 18, 1957.Components. The conversion to electrical energy takes place indirectly, as in conventional thermal power stations. The fission in a nuclear reactor heats the reactor coolant. The coolant may be water or gas, or even liquid metal, depending on the type of reactor. The reactor coolant then goes to a and heats water to produce steam. The pressurized steam is then usually fed to a multi-stage.
After the steam turbine has expanded and partially condensed the steam, the remaining vapor is condensed in a condenser. The condenser is a heat exchanger which is connected to a secondary side such as a river or a. The water is then pumped back into the steam generator and the cycle begins again.
The water-steam cycle corresponds to the.The is the heart of the station. In its central part, the reactor's core produces heat due to nuclear fission. With this heat, a coolant is heated as it is pumped through the reactor and thereby removes the energy from the reactor.
Heat from nuclear fission is used to raise steam, which runs through, which in turn powers the electrical generators.Nuclear reactors usually rely on uranium to fuel the chain reaction. Uranium is a very heavy metal that is abundant on Earth and is found in sea water as well as most rocks. Naturally occurring uranium is found in two different isotopes: uranium-238 (U-238), accounting for 99.3% and uranium-235 (U-235) accounting for about 0.7%. Isotopes are atoms of the same element with a different number of neutrons. Thus, U-238 has 146 neutrons and U-235 has 143 neutrons.Different isotopes have different behaviors.
For instance, U-235 is fissile which means that it is easily split and gives off a lot of energy making it ideal for nuclear energy. On the other hand, U-238 does not have that property despite it being the same element. Different isotopes also have different half-lives. A half-life is the amount of time it takes for half of a sample of a radioactive element to decay. U-238 has a longer half-life than U-235, so it takes longer to decay over time. This also means that U-238 is less radioactive than U-235.Since nuclear fission creates radioactivity, the reactor core is surrounded by a protective shield.
This containment absorbs radiation and prevents from being released into the environment. In addition, many reactors are equipped with a dome of concrete to protect the reactor against both internal casualties and external impacts. Pressurized water reactorThe purpose of the is to convert the heat contained in steam into mechanical energy. The engine house with the steam turbine is usually structurally separated from the main reactor building. It is so aligned to prevent debris from the destruction of a turbine in operation from flying towards the reactor. In the case of a pressurized water reactor, the steam turbine is separated from the nuclear system. To detect a leak in the steam generator and thus the passage of radioactive water at an early stage, an activity meter is mounted to track the outlet steam of the steam generator.
In contrast, boiling water reactors pass radioactive water through the steam turbine, so the turbine is kept as part of the radiologically controlled area of the nuclear power station.The converts mechanical power supplied by the turbine into electrical power. Low-pole AC synchronous generators of high rated power are used. A cooling system removes heat from the reactor core and transports it to another area of the station, where the thermal energy can be harnessed to produce electricity or to do other useful work. Typically the hot coolant is used as a heat source for a boiler, and the pressurized steam from that drives one or more driven.In the event of an emergency, safety valves can be used to prevent pipes from bursting or the reactor from exploding. The valves are designed so that they can derive all of the supplied flow rates with little increase in pressure. In the case of the BWR, the steam is directed into the suppression chamber and condenses there. The chambers on a heat exchanger are connected to the intermediate cooling circuit.The main condenser is a large cross-flow that takes wet vapor, a mixture of liquid water and steam at saturation conditions, from the turbine-generator exhaust and condenses it back into sub-cooled liquid water so it can be pumped back to the reactor by the condensate and feedwater pumps.
In the main condenser the wet vapor turbine exhaust come into contact with thousands of tubes that have much colder water flowing through them on the other side. The largest nuclear power facilityThe is a controversial subject, and multibillion-dollar investments ride on the choice of an energy source. Nuclear power stations typically have high capital costs, but low direct fuel costs, with the costs of fuel extraction, processing, use and spent fuel storage internalized costs. Therefore, comparison with other power generation methods is strongly dependent on assumptions about construction timescales and capital financing for nuclear stations. Cost estimates take into account and storage or recycling costs in the United States due to the.With the prospect that all could potentially be recycled by using future reactors, are being designed to completely close the. However, up to now, there has not been any actual bulk recycling of waste from a NPP, and on-site temporary storage is still being used at almost all plant sites due to construction problems for.
Only Finland has stable repository plans, therefore from a worldwide perspective, long-term waste storage costs are uncertain.Construction, or capital cost aside, measures to such as a or, increasingly favor the economics of nuclear power. Further efficiencies are hoped to be achieved through more advanced reactor designs, promise to be at least 17% more fuel efficient, and have lower capital costs, while futuristic promise 0% greater fuel efficiency and the elimination of nuclear waste. Some operational nuclear reactors release non-radioactive water vaporIn Eastern Europe, a number of long-established projects are struggling to find finance, notably Belene in Bulgaria and the additional reactors at Cernavoda in Romania, and some potential backers have pulled out. Where cheap gas is available and its future supply relatively secure, this also poses a major problem for nuclear projects.Analysis of the economics of nuclear power must take into account who bears the risks of future uncertainties. To date all operating nuclear power stations were developed by or utilities where many of the risks associated with construction costs, operating performance, fuel price, and other factors were borne by consumers rather than suppliers.
Many countries have now liberalized the where these risks and the risk of cheaper competitors emerging before capital costs are recovered, are borne by station suppliers and operators rather than consumers, which leads to a significantly different evaluation of the economics of new nuclear power stations.Following the 2011, costs are likely to go up for currently operating and new nuclear power stations, due to increased requirements for on-site spent fuel management and elevated design basis threats. However many designs, such as the currently under construction AP1000, use cooling systems, unlike those of which required active cooling systems, which largely eliminates the need to spend more on redundant back up safety equipment.Safety and accidents Professor of sociology states that multiple and unexpected failures are built into society's complex and tightly-coupled nuclear reactor systems. Such accidents are unavoidable and cannot be designed around. An interdisciplinary team from MIT has estimated that given the expected growth of nuclear power from 2005 to 2055, at least four serious nuclear accidents would be expected in that period. The MIT study does not take into account improvements in safety since 1970.The most serious accidents to date have been the 1979, the 1986, and the 2011, corresponding to the beginning of the operation of. This leads to on average one serious accident happening every eight years worldwide. Modern nuclear reactor designs have had numerous safety improvements since the first-generation nuclear reactors.
A nuclear power plant cannot explode like a because the fuel for uranium reactors is not enough, and nuclear weapons require precision explosives to force fuel into a small enough volume to go supercritical. Most reactors require continuous temperature control to prevent a, which has occurred on a few occasions through accident or natural disaster, releasing radiation and making the surrounding area uninhabitable. Plants must be defended against theft of nuclear material and attack by enemy military planes or missiles, or planes hijacked by terrorists.
Controversy. The abandoned Ukrainian city ofThe about the deployment and use of nuclear fission reactors to generate electricity from for civilian purposes peaked during the 1970s and 1980s, when it 'reached an intensity unprecedented in the history of technology controversies,' in some countries.Proponents argue that nuclear power is a source which reduces and can increase if its use supplants a dependence on imported fuels. Proponents advance the notion that nuclear power produces virtually no air pollution, in contrast to the chief viable alternative of fossil fuel. Proponents also believe that nuclear power is the only viable course to achieve energy independence for most Western countries. They emphasize that the risks of storing waste are small and can be further reduced by using the latest technology in newer reactors, and the operational safety record in the Western world is excellent when compared to the other major kinds of power plants. Opponents say that nuclear power poses many threats to people and the environmentand that costs do not justify benefits.
Threats include health risks and environmental damage from, processing and transport, the risk of or sabotage, and the unsolved problem of radioactive. Another environmental issue is discharge of hot water into the sea. The hot water modifies the environmental conditions for marine flora and fauna.
They also contend that reactors themselves are enormously complex machines where many things can and do go wrong, and there have been many serious. Critics do not believe that these risks can be reduced through new.They argue that when all the energy-intensive stages of the are considered, from uranium mining to, nuclear power is not a low-carbon electricity source.
Those countries that do not contain uranium mines cannot achieve energy independence through existing nuclear power technologies. Actual construction costs often exceed estimates, and spent fuel management costs do not have a clear time limit.
Reprocessing technology was developed to chemically separate and recover fissionable plutonium from irradiated nuclear fuel. Reprocessing serves multiple purposes, whose relative importance has changed over time. Originally reprocessing was used solely to extract plutonium for producing. With the commercialization of, the reprocessed plutonium was recycled back into for. The, which constitutes the bulk of the spent fuel material, can in principle also be re-used as fuel, but that is only economic when uranium prices are high or disposal is expensive. Finally, the can employ not only the recycled plutonium and uranium in spent fuel, but all the, closing the and potentially multiplying the extracted from by more than 60 times.Nuclear reprocessing reduces the volume of high-level waste, but by itself does not reduce radioactivity or heat generation and therefore does not eliminate the need for a geological waste repository.
Reprocessing has been politically controversial because of the potential to contribute to, the potential vulnerability to, the political challenges of repository siting (a problem that applies equally to direct disposal of spent fuel), and because of its high cost compared to the once-through fuel cycle. In the United States, the Obama administration stepped back from President Bush's plans for commercial-scale reprocessing and reverted to a program focused on reprocessing-related scientific research. Accident indemnification The puts in place an international framework for nuclear liability.However states with a majority of the world's nuclear power stations, including the U.S., Russia, China and Japan, are not party to international nuclear liability conventions. In the U.S., insurance for or radiological incidents is covered (for facilities licensed through 2025) by the.Under the through its 1965 Nuclear Installations Act, liability is governed for nuclear damage for which a UK nuclear licensee is responsible. The Act requires compensation to be paid for damage up to a limit of £150 million by the liable operator for ten years after the incident. Between ten and thirty years afterwards, the Government meets this obligation. The Government is also liable for additional limited cross-border liability (about £300 million) under international conventions ( and Brussels Convention supplementary to the Paris Convention).
Decommissioning is the dismantling of a nuclear power station and decontamination of the site to a state no longer requiring protection from radiation for the general public. The main difference from the dismantling of other power stations is the presence of material that requires special precautions to remove and safely relocate to a waste repository.Generally speaking, nuclear stations were originally designed for a life of about 30 years. Newer stations are designed for a 40 to 60-year operating life. The is a future class of nuclear reactor that is being designed to last 100 years. One of the major limiting factors is the under the action of neutron bombardment, however in 2018 announced it had developed a technique for which ameliorates radiation damage and extends service life by between 15 and 30 years.Decommissioning involves many administrative and technical actions. It includes all clean-up of radioactivity and progressive demolition of the station. Once a facility is decommissioned, there should no longer be any danger of a radioactive accident or to any persons visiting it.
After a facility has been completely decommissioned it is released from regulatory control, and the licensee of the station no longer has responsibility for its nuclear safety.Flexibility Nuclear stations are used primarily for base load because of economic considerations. The fuel cost of operations for a nuclear station is smaller than the fuel cost for operation of coal or gas plants. Since most of the cost of nuclear power plant is capital cost, there is almost no cost saving by running it at less than full capacity.Nuclear power plants are routinely used in load following mode on a large scale in France, although 'it is generally accepted that this is not an ideal economic situation for nuclear stations.'
