Passive systems provide plant safety and protect capital investment. They establish and maintain core cooling and
containment integrity indefinitely, with no operator or AC power support requirements. The passive systems meet the singlefailure
criteria and probabilistic risk assessments (PRA) used to verify reliability. The passive safety systems are significantly
simpler than typical PWR safety systems. They contain significantly fewer components, reducing required tests, inspections,
and maintenance. The passive safety systems have one-third the numbers of remote valves as typical active safety systems,
and they contain no pumps. Equally important, passive safety systems do not require a radical departure in the design of the
rest of the plant, core, RCS, or containment. The passive safety systems do not require reactor coolant fluids to leave
containment or the large network of active safety support systems needed in typical nuclear plants. These include AC power,
HVAC, cooling water, and the associated seismic buildings to house these components.
