Tungsten alloy radiation shielding is the high density metal, which is mixing of a tungsten alloy powder (such as: with content of 92.5 et.% W and the balance of Ni, Fe) with an organic binder. Due to its high density, excellent absorption behaviour against radiation and environmental friendly characteristics, tungsten alloy can be the best choice to produce nuclear submarine tungsten radiation protector.
The Applications of Nuclear Submarine Tungsten Radiation Protector
A nuclear submarine is a submarine powered by a nuclear reactor. The performance advantages of nuclear submarines over "conventional" (typically diesel-electric) submarines are considerable: nuclear propulsion, being completely independent of air, frees the submarine from the need to surface frequently, as is necessary for conventional submarines the large amount of power generated by a nuclear reactor allows nuclear submarines to operate at high speed for long periods of time. Nuclear submarine tungsten radiation protector can be used as radiation shielding for nuclear reactor. Nuclear submarine tungsten radiation protector can be produced into plank boards to separate nuclear engine room from other rooms in nuclear submarine. Nuclear submarine tungsten radiation protector also can be used in the nuclear engine system as the radiation protector encase nuclear reactor to absorb radiation and reduce the damage of nuclear decay.
The Advantages of Nuclear Submarine Tungsten Radiation Protector
Compared to traditional radiation shielding materials such as lead and boron carbide, tungsten alloy radiation bricks provide excellent density with small capacity. At the same tungsten alloy radiation brick with weights high density alloy can provide the same energy absorption as lead using 1/3 less material. During design of shielding, tungsten alloy radiation shielding is calculated according to requirements of shield to abate the multiple shielding materials' thickness.
