Yes, by spontaneous fission, but the nymber of neutrons is very small because the halflife of the spontenuoes fission is: for Uranium 235: (1,0 ± 0,3).1019 years for Uranium 238: (8,20 ± 0,10).1015years
Neutrons are necessary to start a fission reaction. When a neutron collides with a heavy atomic nucleus, such as uranium-235, it can induce the nucleus to split and release more neutrons, leading to a chain reaction.
When uranium-235 undergoes fission, it can produce two or more lighter nuclei, several neutrons, and a large release of energy in the form of gamma radiation and kinetic energy. This process is what powers nuclear reactors and atomic bombs.
When uranium-235 undergoes fission, it releases additional neutrons that can then collide with other uranium-235 atoms, causing them to also undergo fission. This process releases more neutrons, leading to a chain reaction. If the conditions are right and enough uranium-235 is present, this chain reaction can become self-sustaining and release a large amount of energy.
Uranium emits ionizing radiation in the form of alpha particles, beta particles, and gamma rays. The amount of radiation emitted depends on the specific isotope of uranium and its decay products present. Exposure to uranium's radiation can pose health risks, so it is important to handle it safely and follow proper precautions when working with it.
Under nuclear fission with thermal neutrons uranium release an enormous quantity of energy (202,5 MeV per one atom of 235U); the obtained heat is converted in electricity. And we need electricity and heat. also uranium is an alternative to fossil fuels; nuclear reactors don't contribute to global warming and don't release carbon dioxide.

Uranium fission with thermal neutrons release an enormous quantity of energy; this heat is converted in electricity.

The fission of uranium atomic nucleus (especially the isotope uranium-235 which is fissile with low energy neutrons) release a huge energy: 202,5 MeV/fission or 1,68.10ex.8 kJ/mol. The nuclear fission is the source of this energy.
Nuclear fission in a nuclear reactor is initiated by bombarding uranium or plutonium atoms with neutrons, causing them to split and release more neutrons, which then continue the chain reaction.
Uranium-235 and plutonium-239 release alpha, beta, and gamma rays during the process of radioactive decay. Alpha particles are helium nuclei, beta particles are high-energy electrons or positrons, and gamma rays are electromagnetic radiation.
Protons do not directly hit uranium to cause it to split. Uranium undergoes nuclear fission when bombarded by neutrons, not protons. The neutrons are absorbed by the uranium nucleus, leading to its splitting into smaller nuclei and the release of energy.
Uranium undergoes nuclear fission in a controlled process in nuclear reactors. This fission process releases a large amount of heat energy, which is then used to generate steam. The steam drives turbines that are connected to generators, producing electricity.
Uranium-238 emits alpha radiation; its half-life is 4,468×109 year.
Bombarding uranium-235 with a neutron can trigger the nucleus to split into two smaller nuclei and release additional neutrons. This process, known as nuclear fission, generates a large amount of energy in the form of heat and radiation, which can be harnessed for various applications, including power generation in nuclear reactors.
