5.1.2 The' low population zone shall be as shown.in Figure 5.1.2-1,' based on- .

the information given in:Section 2.2 of the FSAR. -

i SITE BOUNDARY "5.1.3 "The SITE BOUNDARY shall be as a shown in Figure 5.1.3-1. For.the

-purpose of effluent release calculations,;the boundary for atmospheric releases is the SITE BOUNDARY and the; boundary for. liquid releas'es'is the SITE BOUNDARY prior to dilution in. the Atlantic Ocean.

5.2- CONTAINMENT CONFIGURATION 5.2.1 The PRIMARY CONTAINMENT is a steel-linedLreinforced concrete structure composed of a-series of vertical right cylinders and truncated cones which iform a drywell. This drywell is attached to a suppression. chamber'through a series of vents. . The suppression chamber is a concrete steel-lined pressure

' vessel in the shape of a torus. The primary containment has a minimum free air' volume of (288,000) cubic feet.
