Steam generator

Description

The invention refers to a steam generator for PWR type reactors. The steam generator has a U-tube bundle arranged within the primary coolant loop, and a feedwater preheater near the cold side of the U-tube bundle. The preheater has two parallel feedwater flow paths running opposed to each other. According to the invention, a lock-up outlet is placed between both flow paths allowing the distribution of feedwater in both flow paths. Modified types are described. (UWI)
