Nuclear rebirth. Analysts grapple with prerequisites

Persons within and without the electric utility industry have begun to recognize the importance of thinking about new ways to generate electricity. The need for a new approach to generation technology in general, and nuclear power in particular, was underscored at a recent meeting of electric power engineers. Utilities will be incorporating smaller, more modular, and more decentralized technology in 100 megawatt packages. Shorter construction lead times and easier licensing, as well as fuel availability and price, will be important criteria. Some foresee the evolution of light water reactors for smaller plants in the short term, and totally new light water and high-temperature gas reactors in the long term. Opinions differ on whether to pursue modifications or new technologies, and whether to standardize or pursue a range of options. Timing is essential because utilities must make commitment while the nuclear industry still has the capability to supply reactors.
