This study describes a methodological proposal to select composite materials which are suitable to be employed to manufacture pipes that can properly withstand environments subjected to gamma and neutronic radiation. The methodology is used to select (see Figure 1) the optimal composite material whose properties are used afterwards to simulate several pipe sections by Finite Element Analysis, comparing the results with a well-known nuclear ferritic steel used in the manufacture of primary loop components. The most suitable composite material according to the defined criteria is composed of a phenolic resin matrix reinforced with long boron fibres and exhibit great properties to be used in a nuclear reactor environment: good radiation resistance and mechanical properties with a very low density and low cost. It can be concluded that, in some cases, composite material pipes could be an interesting alternative compared with usual ferritic steel pipes… See all…<\/strong><\/span><\/a><\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t<\/div>\n\t\t","protected":false},"excerpt":{"rendered":"
