wot Ao iN re fr i NPP AAW! aan STING LORAAT ses FOREWORD BY THE COMMICIION This Progress Report, covering the period June - Nevember 1951, is necessarily confined to the Commission's presently authorized atomic energy program. A joint study of the extent to which atomic energy fa- cilities mignt be further expanded is now being completed for submission to-the Joint Cczrmittee by the Department of Defense and the Commission. Corresponding joint studies are also proceeding in the Nationel Security Council preparatory to a Presidential decision on the reconmendations of the participating egencies. Because of the possibility that an expansion program of some magnitude will be authorized by the President and the Congress, we have taken certain edvance planning steps, within the present availability of funds, Which will assure rapid and orderly execution when and if an expansion program is authorized. The principal positive steps taken are as follows: 1. Two site surveys were begun, one by Stone & Webster for a gaseous diffusion plent, and the cther by the Corps of Engineers for a new reactor location. DOE ARCHIVES Lica 2.
