Title:
INVERSE STEAM GENERATOR FOR FAST NEUTRON REACTOR HAVING LEAD COOLANT
Document Type and Number:
WIPO Patent Application WO/2020/122770
Kind Code:
A3
Abstract:
The invention relates to atomic engineering, specifically to steam generators having a liquid metal coolant. Proposed is an inverse steam generator for a fast neutron reactor having a lead coolant, said steam generator comprising a cylindrical housing having a bundle of heat transfer tubes disposed therein, the ends of said bundle being fastened in tube sheets having intermediate support grids, a spherical inlet chamber and a spherical outlet chamber for supplying a liquid metal coolant, a lower inlet pipe for water, and an upper outlet pipe for steam. The cylindrical housing is arranged horizontally and is bent into a Z-shape having a decrease in height, wherein the bundle of heat exchange tubes is also Z-shaped, conforming to the bend of the cylindrical housing, which allows the structure to be self-compensating, decreases the mass of a steam generator structure, and reduces operational costs.
