The Role of Light Metals in Nuclear Engineering

ALUMINIUM, magnesium and beryllium have been used extensively in research and power reactors chiefly because of their low neutron absorption properties. in this respect, beryllium is superior to magnesium and aluminium. While aluminium and magnesium are used as canning and structural materials, beryllium has been used mainly as reflector and moderator, although attempts are being made to employ it for canning also.The primary functions of fuel element cans in a reactorare : (a) to protect the fuel from corrosion and (h) to prevent the fission products from contaminating the coolant. Simult-aneously the cans should also act as extensible envelopes to accommodate dimensional changes occurring in the fuel due to irradiation and thermal fluctuations. In the case of finned fuel elements, the material should also possess sufficient creep resistance at operating temperatures to withstand the coolant pressure on the heat transfer fins. Other equally important requisites of the cans are good compatibility with fissile material and coolant media and adequate corrosion resistance.
