Nuclear Weapons

The number of people killed by a nuclear bomb depends on various factors such as the size of the bomb, the distance from the blast, and the preparedness of the population. A single nuclear bomb has the potential to kill hundreds of thousands to millions of people instantly or through long-term effects like radiation exposure.

The US signed the Comprehensive Nuclear-Test-Ban Treaty in 1996 which prohibits nuclear testing. Additionally, advancements in technology allow for testing through simulations and monitoring. The US also aims to set an example for other countries to follow suit in reducing nuclear proliferation.

A nuclear war is a conflict between nations or states where nuclear weapons are used, causing massive destruction and loss of life. The use of nuclear weapons can have devastating consequences for both the countries involved and the entire world due to the long-lasting environmental and humanitarian effects.

An atomic bomb is a type of nuclear weapon that releases energy through nuclear fission (splitting of atomic nuclei). Nuclear weapon is a broader term that encompasses atomic bombs, as well as hydrogen bombs which release energy through nuclear fusion (combining atomic nuclei).

Detonation of a fusion hydrogen bomb is initiated by the primary fission bomb, which generates high temperatures and pressures needed to trigger fusion reactions in the hydrogen isotopes. The fission bomb compresses and heats the fusion fuel to the point where nuclear fusion reactions can occur, releasing vastly more energy than the fission reaction alone.

The reactor that had the explosion in entombed. The actual structure is problematical because it will not last nearly long enough. The other reactors have remained in use since the accident. The area around Chernobyl was, and remains, evacuated. A broader area has been taken out of use for various purposes, such as agriculture. Forest fires have to be carefully dealt with because the fires put radioactive materials into the atmosphere. People in the area have health problems that require attention, and the people who have not developed diseases need to be checked carefully for them.

Californium is not typically used in nuclear bombs due to its high cost and limited availability. Nuclear bombs typically use plutonium or uranium as the fissile material for the explosive chain reaction. Californium is used more commonly in research and medical applications due to its ability to produce neutrons.

Nuke is slang for nuclear weapons. Nuclear weapons are nuclear warheads mounted on missiles for neighbourhood ( 200km to 1000km) or intercontinental delivery(>5000km as in case of icbm).Nuclear warhead consist of nuclear bomb. Fissonable plutonium is used as explosive. An uncontrolled fisson chain reaction catalysed by neutrons release so much heat and radiation that it can clean many sq kms of life.

The United States' Three Mile Island Nuclear Power Plant is situated close to Harrisburg, Pennsylvania.

Situated in the Susquehanna River, just south of Harrisburg, Pennsylvania, is Three Mile Island, home to the Three Mile Island Nuclear Power Plant. It is made up of two pressurized water reactors that are referred to as TMI-1 and TMI-2.

The TMI-2 reactor experienced a partial meltdown on March 28, 1979, which is the most famous event related to Three Mile Island. In the history of the US commercial nuclear power generation business, this event is regarded as the most serious accident. The containment structure effectively contained the majority of the radioactive contaminants, despite the reactor core suffering significant damage.

This incident significantly altered public opinion of nuclear power and caused modifications to industry safety policies and practices. TMI-1 kept running following the mishap until its shutdown in 2019.

The yield of a nuclear weapon is its energy release, usually expressed in the weight of TNT that would release the same energy (e.g. kilotons, megatons). It depends strongly on type of bomb (fission or fusion) and many design details.

The USSR built and tested one with 52Mton yield and stated that it was designed for 100MTon yield but they reduced the amount of fusion fuel as they only needed to prove it could work and wanted to minimize damage and fallout from the test.

Ameren's single nuclear plant in Callaway County, Missouri has an output capacity of about 1,190 megawatts.

The decision to possess nuclear weapons typically lies with national governments. Each country makes its own decision based on national security interests, international obligations, and political considerations. The acquisition of nuclear weapons is subject to international agreements such as the Non-Proliferation Treaty, which aims to prevent the spread of nuclear weapons.

Sometimes the workers at nuclear power plants do get contaminated. In general the contamination is mild, and most workers never experience such a thing. A few have been seriously injured by radiation, but, aside from the Chernobyl and Kyshtym disasters and the Windscale Fire, this has very rarely happened.

Aside from the three accidents mentioned above and contamination from nuclear bombs, the worst radiation contamination problems have been outside the nuclear industry. The so called Radium Girls are one example, in which contamination killed a number of workers at different industrial facilities in the United States during the 1920s. The worst recent contamination problem was the Goiania accident, in Brazil in 1987, in which radioactive cesium was distributed from abandoned medical equipment.

J. Robert Oppenheimer was the former scientific director of the Manhattan Project and joined Albert Einstein in opposing the development of the hydrogen bomb due to its destructive power and potential consequences for humanity. Oppenheimer played a key role in the development of the atomic bomb during World War II and later became a vocal advocate for international cooperation and nuclear disarmament.

A nuclear blast can have devastating effects, including heat, blast pressure, and radiation that can result in immediate death. The impact of a nuclear blast depends on various factors, such as the distance from the explosion and the size of the bomb.

The nuclear fuel in the weapons can be used, especially the U-235 content. In fact I believe this is being done in the US with weapons being deactivated. The U-235 will have been enriched to a high level for weapons so the process involves mixing it with depleted U (mostly U-238) to get the required 5 percent or so for reactor fuel. Plutonium can also be used when extracted from weapons, but this requires another plant for producing fuel with a mixture of U and Pu, so called MOX fuel. I don't think there is a plant in the US to do this at present, but it will no doubt come, with excess Pu available it is the best thing to do with it.

Both hydroelectric plants and nuclear power plants generate electricity by converting a source of energy into electrical power. They are both considered to be reliable sources of base-load power, meaning they can provide a continuous and consistent power output. Additionally, both types of plants have the potential to produce significant amounts of electricity and have a relatively low carbon footprint compared to fossil fuel power plants.

U.S. President Ronald Reagan and Soviet President Mikhail Gorbachev came within a hair's breadth of agreeing to phase out their stockpiles of nuclear weapons. General Zhu Chenghu of China's National Defense University, made some remarks that stirred an unusual uproar in the West and in the United States in particular. According to reports in the Western media, Gen. Zhu, in responding to questions in a briefing session on China's foreign and security policy with a delegation of foreign journalists based in Hong Kong, seemed to indicate that in a possible military conflict with the United States over Taiwan, Beijing would be no match for the United States in terms of conventional capability. Zhu thus suggested that China should perhaps be the first to use nuclear weapons to deter a possible U.S. intervention.

Today, the United States is the only nuclear power that continues to deploy nuclear weapons outside its own territory. The approximately 480 nuclear bombs in Europe are intended for use in accordance with NATO nuclear strike plans, the report asserts, against targets in Russia or countries in the Middle East such as Iran and Syria. Israel has not confirmed that it has nuclear weapons and officially maintains that it will not be the first country to introduce nuclear weapons into the Middle East. Yet the existence of Israeli nuclear weapons is a "public secret" by now due to the declassification of large numbers of formerly highly classified US government documents which show that the United States by 1975 was convinced that Israel had nuclear weapons But as the questions says, there should no be nuclear weapons.

A nuke can cover up to 200 miles. Mega Ton nukes blow up even farther. But the real affect of a nuke is the radiation. One nuke can spread radiation all over Europe. If you do get radiation you die in 2 days.

Though the answer above overstates the case they can be truly devastating.

The effect of a nuclear weapon depends on the 'yield' of the bomb.

The yield is measured in equivalent tonnage of TNT exploding but this is only an indication of the blast and not the radiation.

The bomb dropped on Hiroshima had an equivalent tonnage of 15 -20,000 tons of TNT.

The weapons today can be constructed in the millions of tons range easily.

It is estimated that Russia has enough nuclear weapons to destroy the Earth multiple times over. A nuclear war involving Russia's full arsenal could lead to catastrophic global consequences, including nuclear winter and widespread destruction.
