You don't give any information about what sort of item this applies to. Generally for components that are going to be exposed to the high neutron flux in a reactor, the material has to be chosen so that it will still have an adequate life, maybe the whole life of the plant if it is not replaceable. This would apply to the steel of the pressure vessel for example. So it's a way of classifying materials to make life easier for designers, and ensure the plant safety and durability
Reactor-grade uranium is not suitable for making a bomb because it contains a lower concentration of the fissile isotope U-235, which is necessary for sustaining a nuclear chain reaction required for a bomb to explode. The U-235 content in reactor-grade uranium is too low to achieve the rapid and efficient chain reaction needed for a nuclear explosion.
It can produce low grade plutonium that need be extracted from the used nuclear fuel through used fuel reprocessing. However, power reactors are subject to the international nuclear safeguards to prevent its misuse.
Plutonium is not typically bought or sold on the open market due to its highly regulated nature and potential for misuse in nuclear weapons. It is primarily used in nuclear reactors and weapons programs under strict government control. The value of plutonium is difficult to estimate, but it is considered extremely valuable due to its rare and highly radioactive properties.
No, a reactor is operated at critical and a bomb at supercritical. Also reactors include safety shutdown systems that quickly make them subcritical stopping the reaction.However reactors can have steam explosions and hydrogen/oxygen explosions. These are physical and chemical explosions respectively, not nuclear.

Nuclear grade resins are specifically designed to meet the strict requirements of the nuclear industry, such as high purity and radiation resistance. They undergo more rigorous testing and quality control to ensure they can withstand the harsh conditions in nuclear facilities. Non-nuclear grade resins, on the other hand, are used in general industrial applications that do not require the same level of performance or quality control.
No nuclear plant I know of uses weapons grade fissile material. This is strictly controlled for military use only.
No...but I'm a nuclear physicist
Reactor grade material is usable in most nuclear power plants. Weapons grade material is required for nuclear weapons. For uranium the difference between reactor grade and weapons grade is the level of enrichment: less than 20% uranium-235 is reactor grade, greater than 20% uranium-235 (greater than 90% is prefered) is weapons grade. For plutonium the difference between reactor grade and weapons grade is the level of contamination with plutonium-241: any amount of plutonium-241 is OK for reactor grade, only low levels of plutonium-241 are acceptable in weapons grade as its spontaneous fission rate can cause the bomb to fizzle.
Weapons grade uranium contains a substantially larger fraction of the radioactive isotope 235U than does reactor grade uranium.

No, the fuel used won't be weapons grade, just industrial grade. The fuel will get very hot though and could cause non nuclear explosions, which will cause radioactive dust to be released into the surroundings.
Weapons-grade plutonium is a specific grade of plutonium-239 that is highly purified and contains a high percentage of the fissile isotope. It is used in the production of nuclear weapons due to its ability to sustain a chain reaction in a nuclear explosion. It is tightly regulated and controlled to prevent its misuse for non-peaceful purposes.
If you think to nuclear grade: uranium and plutonium very pure, the maximal values for impurities being limited by specifications as ASTM in USA, etc.
Nuclear grade concrete is a method of qualifying, procuring and quarantine of constituent concrete materials. These qualified materials are then introduced into a manufacturing process that incorporates qualified equipment, processes and personel into a material that's meets strict reqirements for public safety.
The nuclear wall is not a scientifically recognized structure. It may refer to the nuclear envelope, a double membrane that surrounds the nucleus of eukaryotic cells, or it could be a misunderstanding of the nuclear membrane or nuclear lamina, which are components of the nuclear envelope.
