Graphite is a good reflector. In graphite moderated gas cooled reactors an extra layer of graphite is provided surrounding the core which helps to reflect neutrons which would otherwise escape, back into the core.

What is an example of the different materials that causes light to absorb reflect or transmit?
Glass, clear plastics, perspex, most gases
Which two particles have roughly the same mass?
Protons and neutrons have almost the same mass.
Is an nucleon a collective name for two particles?
Yes, protons and neutrons.
What two particles are in the nucleus?
(The constituent particles of an atom are the electron, the proton and the neutron; all three are fermions. However, the hydrogen-1 atom has no neutrons and the hydron ion has no electrons.) WIkipedia
What is the difference between Material take off and Bill of materials in piping?
A Material Takeoff is the process of analyzing(this includes list of materials with quantities and types,grades of materials and the weights of such materials) drawings and determining all the materials required to complete the design. A Bill of Materials is adocument that shows detailed desgriptions of materials used in completing a project,this includes,types of materials,specification of each item,gost of each item used,number and cost of labour used in completing the poject. The major difference between the two is:MTO is needed to make a BOM,a BOM aids in the procurement and requisition of materials.
Where does the nuclear energy come from?
Uranium atoms (and oter fissionable materials) absorb neutrons, which cause the atoms break apart, resulting in two fission products, two or three more neutrons, and alot of energy in the form of heat. This heat turns water into steam, and this steam drives a turbine, which drives a generator, which produces electricity.
List two materials required for composite making?
Carbon and glass fiber are two materials that are required for composit making.
Which subatomic particle is present in the nucleus of an atom?
The atomic particles that make up an alpha are two protons and two neutrons. The subatomic particles are contained within the neutrons & protons and there are too many to list here, plus I don't know all of them.
An atom of which element contains two neutrons?
Two isotopes have two neutrons: 3H and 4He.
What atom has two protons and two neutrons?
It is helium, specifically the helium-4 isotope, that is composed of two protons and two neutrons.
The radioactive particle that is positively charged and has two protons and two neutrons is the?
An alpha particle consists of two protons and two neutrons.
Is alpha radiation absorbed by paper?
Alpha radiation (a Helium atom with two neutrons) is very bulky, and therefore cannot penetrate physical objects easily. A sheet of paper will not absorb, but deflect the alpha particle.
How many electronsprotonsand neutrons does helium have?
Helium has two protons, and, in its neutral state, two electrons. It can have either one or two neutrons.
What is the charge on two neutrons?
Each neutron has an (electrical) charge of zero. For two neutrons, 0 + 0 = 0.
List two materials that become hot easily?
There are a wide variety of materials that become hot easily. Two examples would be leather and asphalt. Both can become extremely hot in just a matter of minutes.
Does hydrogen have two protons and neutrons?
No, it only has 1 proton and usually no neutrons.
How many neutrons are in helium?
He-4 isotope has 2 neutrons. He-3 isotope has 1 neutron
