ABSTRACT:
In a known design of liquid metal cooled fast fission nuclear reactor, the primary pumps (22) plug into the outboard ends of the high pressure pipes (28), leading to the development of a vertical load which has to be supported by substantial additional structure to avoid subjecting the reactor diagrid (18) to significant bending moments. The invention resides in connecting the inboard ends of the high pressure pipes (28) to the diagrid (18) via spigot and socket joints (40) so that the pipes are not rigidly connected at either end. With this arrangement loads are developed at each end of the pipes which combine to produce radial reaction loads acting on smaller moment arms whereby the total moments imposed on the diagrid are reduced.
