Water supply system overview

Earlier in this chapter we quoted the terrorist Ramsi Yousef in a statement he made about using chemicals as weapons. for use against vital institutions and residential populations and drinking water sources and others.. .. A prime source of concern in any overview of CBW terrorism must be the US water supply, a complex system that feeds the nations thirst for water. Thousands of companies and utilities bring water to homes, businesses, and industry. The New York City water system alone, for example, supplies 1.3 billion gallons per day to its customers. In California, where a complex manmade water system made possible the very existence of Los Angeles, the water supply now serves 3.8 million residents. 

The schematic overview of the plant system concept is shown in Fig. X-1. In RMWR, natural circulation core cooling is introduced and hence, circulation pumps and the related power supply can be eliminated. This results in a simplified and economic core cooling system. In this system, gravitational steam/water separation is expected due to the low steam velocity from the core and, hence, the steam/water separator and the steam dryer can also be eliminated.
