A. INTRODUCTION
B. DISCUSSION
It is the policy of the Atomic Energy Commission The power levels of water-cooled nuclear power to encourage, support, and give priority consideration to plants have shown a continual increase from about 600
activities leading to greater standardization of nuclear megawatts electric in 1965 to slightly above 1,300
megawatts electric in 1973. The continual increase in the power plants. In a statement issued on March 5, 1973, size of these plants has resulted in plant design implementing that policy, the Commission stated that modifications and a large expenditure of' AEC staff the size of all new plants accepted for licensing review review effort to assure the maintenance of a consistent (both those proposed for review as standardized plants level of safety. These numerous plant design variations, and those proposed for review in connection with a coupled with the rapidly increasing number of specific application for a construction permit) would be applications, have contributed to the steady growth in limited to power levels of less than 3,800 megawatts the required licensing ieview time to evaluate such applications.
