I just thought of a simple casuc method that sort of relies on an exploit.
I just tested an electric wrench in a deployer from redpower. They work fine. So, here's the plan : put uranium cells into a reactor, run it until it overheats, then have the deployer wrench the reactor and suck up the reactor and uranium cells.
Another deployer replaces the reactor and pneumatic tubes re-insert the uranium cells.
You also have to automatically recharge the wrench, you have to use an electric wrench in lossless mode.
