A New Algorithm for a Condenser Design for Large-Scale Nuclear Power ...
Abstract This work presents a new velocity search algorithm for designing a condenser of a 1200 MW e large-scale nuclear power plant situated in tropical region. For this, the condenser pressure was considered in the range of 7.5–15 kPa while its tube inner diameter was taken as 28 mm with 1 mm tube wall thickness.

Thermal performance assessment of steam surface condenser
The configuration of steam condenser as shown in Fig. 1, is a shell and tube type heat exchanger. Cooling water (CW) enters to the tubes, through tube sheet and the shell side of condenser receives steam from exhaust of LPT. Steam passes over the shell side and cooling water flows through tube side.
