5.4 Containment Applicability: Applies to those design, features of the containment relating to operational and public safety.

Objective: To describe the significant design features of the reactor containment structure. N w

Specifications: A. Reactor Containment '" <,

1. The reactor containment shall be a stee lined reinforced concrete structure having a net free 6

volume of approximately 2.2x10 cubic feet.g, t ..

2. The materials used in construction shall confgtm to the codes specified in Table 6.2-4 of the UFSA'R.

3. The stress levels in the structure shall not exceed those specified in Section 6.2.1 and Table 6.2-3 of the UFSAR.

Basis: The containment is designed to limit the consequences of any release of radioactive material from the reactor coolant system. The internal pressure used in the design is 40 psig and the ground acceleration in the maximum postulated earthquake is 0.17 g at zero period. The' containment design will withstand wind velocities up to 300 mph and snow or ice loads of 30 psf. However, no snow or ice loads are included in combination with internal pressure and seismic loads, because they-would reduce the tension in the walls. The containment will also withstand an internal vacuum of approximately 7.5 psi. However, it is inconceivable that such a pressure differential could occur.
