KSNP consist of a NSSS with a pressurized water reactor & 2 steam generators, a<br />

BOP(Balance of Plant) with a turb<strong>in</strong>e & associated auxiliaries. Overall system parameters<br />

are described <strong>in</strong> the follw<strong>in</strong>g table;<br />

1.2.2. Reactor & NSSS(Nuclear System Supply System)<br />

[Fig. 1.6] shows the major components of the KSNP Nuclear Steam Supply System such<br />

as Reactor, Reactor Coolant Pumps & Steam Generators. The heat generated <strong>in</strong> the<br />

Reactor is removed by the reactor coolant and is transferred to the Steam generators.<br />

The RCS consists of two loops, identified by the labels on the diagram. Each of the two<br />

loops has a 'hot‐leg' and two 'cold‐leg' to complete each loop. The reactor coolant water is<br />

cont<strong>in</strong>uously circulated through each loop by four Reactor Coolant Pumps which located<br />

at each cold‐leg.<br />
