1Title:  Exterior view of the A1W prototype, Idaho National Laboratory Add
 Summary:  An exterior view of the A1W prototype plant at the Idaho National Laboratory. A1W was the prototype for the Enterprise A2W shipboard reactor plants; the prototype contained two reactors and the steam plant equipment to power one shaft. Data from the A1W prototype were also used in the design of the C1W reactor plant, which powered the USS Long Beach.

2Title:  A1W under construction at the Idaho National Laboratory Add
 Summary:  The A1W prototype, under construction at the Idaho National Laboratory. Heat-dissipating spray ponds used by the S1W prototype are visible in the foreground. A1W was a two reactor, one steam plant/shaft prototype plant, parallel to one of the Enterprise's four propulsion plants. Construction of the A1W prototype began in the spring of 1956; first criticality for the first of its two reactors was achieved in October 1958. As with the S1W plant and the Nautilus, the design and construction of the A1W prototype slightly led that of the USS Enterprise.

3Title:  Exterior view of the A1W (Enterprise prototype) at the Idaho National Laboratory Add
 Summary:  The A1W prototype (center) at the Idaho National Laboratory. Construction began on the A1W in April 1956; the prototype consisted of two reactors and the steam plant equipment necessary to drive one shaft. The first A1W reactor reached full power on 17 January 1959 and both reactors operatored together at full power for the first time on 15 September 1959.

4Title:  Naval Reactors Facility at the Idaho National Laboratory Add
 Summary:  An aerial view of the Naval Reactors Facility at the Idaho National Laboratory. NRF was the site of the S1W, A1W, and S5G prototypes. The site's Expended Core Facility remains open to support the processing of spent fuel from United States naval reactors.

5Title:  Tour of "USS Enterprise" and report on Joint AEC Naval Reactor Program Add
 Summary:  This document is based on a hearing that members of the Joint Committee on Atomic Energy conducted on board the USS Enterprise in the spring of 1962. The hearing touched on a number of issues, involving both capabilities and costs, which factored into the adoption of nuclear propulsion for aircraft carriers. The first commanding officer of the Enterprise, Vincent P. de Poix, summarized the benefits of nuclear propulsion for carriers, including the ability to rapidly position the ship for air operations, the ability to sail to a trouble spot because of the carrier's support for sustained high-speed propulsion, and the absence of stack gases in the flight deck area, which minimizes aircraft corrosion in comparison with operations on an oil-fired carrier. The qualitative advantages that de Poix summarized, however, were weighed against quantitative advantages emphasized by Secretary of Defense Robert McNamara, who recommended in 1963 that the next carrier to be built (CV-67) be conventionally-powered. The hearing also provides a nice summary of the naval nuclear propulsion training program, including the role of the Idaho National Laboratory's A1W prototype. Both the Enterprise's Reactor Officer, D.P. Brooks, and the ship's Engineering Officer, R.S. Smith, testify at the hearing and describe training approaches and the organization of the Enterprise's nuclear-trained officers and operators on the ship. The hearing document also includes "A treatise on nuclear propulsion in surface ships." This study was commissioned by Admiral Arleigh Burke, Chief of Naval Operations, in late 1960 and was completed in early 1961. It detailed both the favorable and limiting aspects regarding the adoption of nuclear propulsion in surface ships. A cost factor of 1.5 was included in the study. As summarized by historian Francis Duncan, this finding suggested that "the navy could buy ten nuclear-powered ships or fifteen oil-fired ships of the same type for the same total sum." Admiral Hyman Rickover (Director, Naval Nuclear Propulsion) also testified at this hearing and addressed both this cost factor and the capabilities provided by nuclear propulsion. Finally, pages 54 through 56 of the hearing document include Rickover's summary of Shippingport Atomic Power Station reactor attributes and the potential benefits that the work at Shippingport could have for the nation's commercial nuclear power industry.
