This means that the nuclear material is of a high enough concentration to fissile (allow for a fission chain reaction). This is because Uranium comes naturally as 99.3% U238, which cannot sustain fission, and .7% U235, which is what they want for the fuel. So they have to find away to pull away the U238 and leave the U235. As they concentrate the U235, it becomes concentrated enough so that it can sustain fission (too much U238 bogs down the reaction and will eventually end the fission). When it reaches this point of concentration, it is concidered reactor grade. Different elements have different needed concentrations to reach this level.

The papers published have received a passing grade from experts in the field.
What is the Volume of jacket in 4kl glass lined reactor?
20% of that reactors capacity (while ss reactor or glasslined reactor)
Which of planets is an immense fusion reactor in space?
None of the planets is a fusion reactor. The sun is a fusion reactor but it is not a planet.
What is meant by grade of a threaded fastener?
A grade denotes the mechanical properties of a screw - the materials used, size, direction of the thread and so on.
How does weapon-grade uranium differ from nuclear-reactor-grade uranium?
Weapons grade uranium contains a substantially larger fraction of the radioactive isotope 235U than does reactor grade uranium.

Canning materials used in nuclear reactor?
uranium
What is the difference between fuel of nuclear power plants and the fuel needed to construct a nuclear weapon?
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.
What materials can be used as fuels for a nuclear reactor?
Uranium and most transuranic elements. Plutonium and Americium are particularly good reactor fuels.
What is meant by drum foundation which is used for supporting reactor turbines?
hvfv
What materials is used as controller in a nuclear reactor power generator?
cadmium
What is meant by nuclear reactor?
It is a device where a controlled nuclear fission chain reaction occurs.
What is in a nuclear reactor?
Shielding is the use of materials to absorb free or loose radiation, and prevent it from leaving the reactor; this would be a hazard to workers otherwise. The standard materials are concrete and lead, for their ease of use and installment, low cost and high effectiveness.

How they grade sandblasting materials?
They grade sandblasting materials by their overall abrasiveness and size. This determines how quickly they remove material and how destructive they are in general.
