The Doomsday Machine

Where did Roddenberry state that the impulse engines were fusion-powered? In TMoST, Whitfield and Roddenberry tell us the impulse drive can run for a month before their fuel is exhausted, but nothing about their power source. I vaguely remember reading them described as "atomic powered" and the sheet accompanying the AMT model said they employed the same principal of propulsion as "rockets". But I don't recall ever seeing Roddenberry describe the original ship as having a fusion-powered impulse drive.
states that overloading (I think - lemme spin the DVD to confirm) the impulse engines will cause a "fusion explosion", so the credit for this particular data point may have to go to Norman Spinrad.
