Abstract

See full text

A method for manufacturing an article, e.g. a nuclear pressure vessel. The method involves: a) charging at least one hopper with steel powder; b) supplying an oxide stripping medium to the steel powder in the at least one hopper; c) removing the oxide stripping medium and any oxide particles stripped from the steel powder from the at least one hopper; d) discharging the oxide stripped steel powder into a can that provides a mould for the article; and e) converting the steel powder to solid steel by hot isostatic pressing to form the article. Stripping the steel powder of oxides whilst the steel powder is in the at least one hopper optimises desirable material properties of the article and thereby quality and safety of the article.
