Commercial HWRs have demonstrated many achievements as an electrical power generation system. These achievements include an excellent safety record, high annual and lifetime capacity factors, low fuel cost and a broad range of other performance strengths which together indicate that the technology is fundamentally sound. HWRs have an excellent potential for continued development. The separation of the coolant and moderator systems provides an opportunity for development of enhanced safety features. The known capabilities not yet fully exploited and future opportunities offered by the flexibility for advanced fuel cycles and diverse applications indicate that the HWR technology will continue to pay strong dividends on research, development, and design investment
