You don't give the examples, but the moderators used are 1. Heavy water 2. graphite 3. light water.
Yes, nuclear power is used in England. The country has several nuclear power plants that contribute to its energy production and help meet electricity demand. Nuclear power is among the mix of energy sources in England alongside renewables and fossil fuels.
The choice with a negative charge among the following options is the electron.
The radioisotope with the shortest half-life among the following options is Polonium-214.
The best example of a weak force among the following options is gravity.
If you mean why are all current nuclear power plants fission reactors, this is simply because the creation and control of nuclear fusion reactions on a scale and level suitable for commercial purposes are not currently well-understood. Experimental reactors can create and hold a plasma for a short period, and sometimes realise a small net gaing in energy, but none currently can run for an extended period. They are also technical challenges remaining around containment of the plasma and degradation of the plasma vessel due to neutron damage. The current wisdom among fusion researchers is that "commercial fusion power has been 50 years away for the last 50 years...."
Fast neutron nuclear reactors, among other new Nuclear technologies. Nuclear power is the cleanest most efficient power source. Reducing burning of fossil fuels will significantly reduce pollution in the atmosphere.

Mainly I believe because the light water PWR was developed for submarines and as compact a reactor as possible was required. Since then of course it (and BWR's) have been up-sized very successfully. Enriched fuel can now be made much more easily and cheaply by centrifuges than by the diffusion method, so to obtain low enriched fuel is more economical. There is also MOX available, though I don't think the US uses this. See the discussion page as well
According to some sources among the diplomats, this is a likely scenario.
The neutrons released from Uranium are fast neutrons. In a reactor they are slowed down by a moderator. The moderator could be water, heavy water, graphite, among others. When the neutron is slowed down, it is more likely to create fission.This is what happens with the U-235. The U-238 does not fission, but it does transmute through a series of neutron absorption and beta decay etc. into plutonium which does fission also.
The tritone interval is the most dissonant among the following options.
Nuclear power is the major source of energy among all nations.
The choice with a negative charge among the following options is the electron.

Nuclear power is among the most reliable and safe sources of carbon free electricity.
Nuclear material for nuclear reactors are usually obtained from uranium. Uranium is obtained from uranium mines (open pit or underground mines) the same way mining for other minerals. Uranium then passes through different processes until getting it in a suitable form for fabrication into nuclear fuel.
