DOE-HDBK-1017/2-93Plant MaterialsPROPERTIES CONSIDERED WHEN SELECTING MATERIALSFabricabilityFabricabilityis a measure of the ease with which a material can be worked and made intodesirable shapes and forms. Many components of a nuclear reactor have very complicatedshapes and forms and require very close tolerances. Therefore, fabricability is animportant consideration in the manufacturing of these components.HeatTransferGood heat transfer properties are desirable from the fuel boundary to the coolant in orderthat the heat produced will be efficiently transferred.For a constant amount of heat transfer, a degraded heat transfer characteristic requireshigher fuel temperature, which is not desirable. Therefore, desirable heat transferproperties in the selection of reactor materials, especially those used as core cladding andheat exchanger tubes, are a major consideration.CostCapital costs for building a typical nuclear facility can be millions of dollars. A majorportion of the cost is for plant material; therefore, cost is an important factor in theselection of plant materials.MechanicalStrengthPreventing release of radioactive fission products is a major concern in the design,construction, and operation of a nuclear plant. Therefore, mechanical strength plays animportant role in selecting reactor materials. High mechanical strength is desirable becauseof its possible degradation due to radiation damage and the need to contain the radioactiveliquids and fuel.Rev. 0Page 3MS-05
