I got what I concider technical general knowledge and since most things are built with the same physical building blocks its only to piece together the puzzle och perhaps put togheter an new one with the pieces on hand. I can bet you a beer on being able to describe the overall function of more then 50% of any random system in a powerplant. But I might need a dictionary to do it in english.

Understanding a process, its components and how everything is interrelated is the easy part. The hard part is to describe it in math and then optimise it.

A PWR can have as large a condenser as a BWR but why build it if you can dump non radioactive steam to the atmosphere?  Its not acceptable for a BWR since there is no heat exchanger between the reactor core and the turbine island. (I dident think about that option for PWR:s, this is not a throughly overworked texts. )

Perhaps you can tell med why PWR:s dont have a steam condensing pool?

BWR:s have steam dump pools where steam from an insulation vale closure of the get blown thru overpreassure alves into a pool of cold water inside the containment where it condenses. (I write this to keep it intresting for the general reader. Did you get my email? )

As far as I know PWR:s have a larger containment withouth such a pool and dump the steam inside the containment. The containments preassure can then be lowered by pumping sump water from the bottom of the containment thru sprinklers in the roof.  The size of the containmnet is probably due to the need to have the heat exchangers, that is steam generators inside it and to be able to lift components for service.

Do this automatically give enough volume to make blowdown into a pool unneceserry?  It seems like it would be a nice passive system to keep the preassure buildup down and give less wear on installations inside the containment.
