Abstract

973,158. Dashpots. COMMISSARIAT A L'ENERGIE ATOMIQUE. Feb. 3, 1961 [Feb. 5, 1960], No. 4114/61. Heading F2S. [Also in Divisions G6 and H2] The control rod 7, Fig. 15, of a nuclear reactor is connected to a cylindrical member 109 integral with the lower end of which is a tubular bush 108 which, at the end of its travel when the member 109 is projected downwards, covers a tubular support 118 and this has the effect of damping the fall of the rod 7, the bush 108 having openings 119 and together with the support 118 constituting a dash-pot. In Fig. 15, the openings 119 are shown as increasing in size towards the lower end of the bush 108.
