It takes about 15 secs to complete 1 compression. Since you need to cool 1690 heat you need 8,45 ice blocks per second. In order to produce them fast enough you need atleast 127 compressors. Now i didnt even started about the insane piping system you would need to distribute the stuff evenly
You would need 50 million eu just to compress all those snowballs for each cycle. That would make the output of this reactor less than mine while this reactor is way more expensive than mine even if you TMI its still easier to make 2 of my bucket nuclear reactors. Its a nice design you have but other than coolness and fun it doesnt have any value.
Conclusion: you are better off making a water bucket based nuclear reactor.
