The history of nuclear propulsion and Rickover's influence and involvement is substantial. Due to the importance and impact of nuclear power, the AEC commissioned the creation of two related historical records to capture important facts of both naval nuclear propulsion and the Shippingport commercial reactor. Both of these official documents necessarily contain a good deal of information on Rickover's choices, methods and technical philosophy in the development of practical nuclear power, but are not biographies. While Rickover cooperated to provide real-time access to facilities, people and records, according to the authors he did not edit; Rickover was in-fact deceased before the second document was completed. These are: (1) "Nuclear Navy, 1946-1962" by AEC staff historians Richard G. Hewlett and Francis Duncan, and (2) "Rickover and the Nuclear Navy: The Discipline of Technology" by Francis Duncan. The AEC makes both of these documents directly available to the public in digital form.
