It means the nucleus will fission or split into two halves (or near halves). Most frequent example is Uranium-235
Uranium 235 is the most important isotope of uranium; it is a fissionable isotope used in HWR, PWR, BWR, research reactors and other types of reactors. But it is rare, only 0.72% of natural Uranium is this isotope.The more plentiful Uranium 238 isotope is only fertile not fissionable; it can only be used in fast reactors to breed Plutonium, which is fissionable. Isotopes of plutonium 239Pu and 241Pu are highly fissionable and importants for nuclear fuels.
Uranium (especialy the fissile isotope) 235U is fissionable by bombardments with thermal neutrons.
The fissionable isotope of uranium is uranium-235 (U-235). While natural uranium contains about 99.3% uranium-238 (U-238) and only about 0.7% U-235, it is the U-235 isotope that can sustain a nuclear chain reaction. U-235 is used in both nuclear reactors and atomic bombs due to its ability to undergo fission when struck by a neutron.
235U is a fissionable isotope and 238U is a fertile isotope; these isotopes are extremely important in the production of nuclear energy. Also uranium is used by the United States, United Kingdom and Russia to threaten with nuclear bombs the other countries, without nuclear weapons.
Uranium-238 is fissionable. Its just not what we call fissile, which has the added definition of, when fissioned, producing neutrons that can go on to fission more atoms. Uranium-238 is more correctly called fertile, which means that a neutron can transmute it into another isotope, such as plutonium-239, which is fissionable and fissile.Uranium-235, on the other hand, is both fissionable and fissile.
The fissionable isotope is required for the nuclear reactor operation. The fissionable isotope when fissions it give energy due to the mass difference according to Einstein formula E = mc2
Yes, this isotope is very fissionable and is used in nuclear reactors and nuclear weapons.

Certain fissionable materials, usually a uranium or plutonium isotope.

To make a nuclear bomb, you need the fissionable material such as a Plutonium239 isotope, an explosive to start the nuclear chain reaction, a detonator, and a pusher.
Uranium-235 is a fissionable isotope that can achieve critical mass under the right conditions, leading to a nuclear explosion. This explosion can release a massive amount of energy, potentially causing devastating destruction and radiation. The force generated by such an explosion could indeed be powerful enough to propel material to the outer limits of the solar system.
U-235 is the fissionable isotope that produces the power. Reactor fuel usually contains about 5% of this, the rest being U-238
The bomb dropped on Nagasaki, Japan, on August 9, 1945, was called "Fat Man," and it utilized plutonium-239 as its fissionable material. Plutonium-239 is a synthetic isotope produced in nuclear reactors from uranium-238. The design of the bomb was an implosion-type nuclear weapon that relied on compressing the plutonium to achieve a critical mass and initiate a fission chain reaction.
235U is a fissionable isotope and 238U is a fertile isotope; these isotopes are extremely important in the production of nuclear energy. Also uranium is used by the United States, United Kingdom and Russia to threaten with nuclear bombs the other countries, without nuclear weapons.
Subcritical mass is the quantity of fissionable material that cannot sustain a nuclear reaction. When the amount of fissionable material is below the critical mass required to sustain a chain reaction, it is considered subcritical.
