ABSTRACT
In this section, many types of early reactors will be examined. Many of these were built in the United States as experimental or demonstration projects. Other countries pursued identical and other technologies. Some of these technologies were not developed beyond the experimental stage, but they are now being reconsidered for future use. Many of these reactors are listed in Table 1.1. The primary reference for the information summarized in this section is contained in Nuclear Power Engineering by M. M. El-Wakil.
