A radially-acting restraint for a graphite reactor moderator structure is described. The peripheral restraint is characterized in that between the restraint means and the moderator structure is interposed a series of wedges imposing a centripetal force on the moderator structure and a spring loaded thrust rod, radiation shielded, for applying a load to the wedges. The wedges are cuboids divided into three equal parts by two cuts each extending outwardly from the same diagonal of the top face and finishing on the ends at the bottom face which is transverse to the diagonal of the top face, the upper edge of the center part and the lower corners of the outer parts being removed. A series of the wedges are imposed one upon the other and the angle of the cuts is made progressively more acute from wedge to wedge down through the series. (N.W.R.)
