SentinelDualit, i totally agree that's why i'm looking for a better way of cooling system. Sorry i'm french and my english is very... crazy xD
a good design, though i would suggest using lattices to help heat dissipation. the current design means only a single surface is exposed to the heat of the reactor, and your coolant water will migrate towards the outside edge for a variety of reasons (inertia, pressure generated by expanding steam, etc)
