Bases:
4.7 A. Primary Containment The water in the suppression chamber is used only for cooling in the event of an accident; i.e.,
it is not used for normal operaticn; therefore, a weekly check of the temperature and volume is adequate to assure that adequate heat removal capability is present. For additional margin, these will be checked.once per day.
The interiors of the drywell and suppressicn chamber are painted to prevent rusting. The inspec-tion of the paint during each major refueling outage, approxinately once per year, assures the paint is intact and is not deteriorating.
Experience with this type of paint inlientes that the inspection interval is adequate.
Because of the large volume and thermal capacity of the suppression pool, the volume and temperature normally changes very slowly and monitoring these parameters daily is sufficient to establish any temperature trends, By requiring the suppression pool temi crature to be cont inually monitored and frequently logged during periods of significant heat addition, the temperature trends will be closely followed so that appropriate action can he talen. The requirement for an external visual examination following any event where potentially high loadings could occur provides assurance that no significant damage was encountered.
Particular attention should be focused on structural discontinuities in the vicinity of the relief valve discharge since these are expected to be the points of highest stress.
Visual inspection of the suppression chamber inclu ling v.ater line regions each refueling outage is adequate to detect any changes in the suppression chamber structures.
The primary containment preoperational test pressures are based upon the calculated primary containment pressure response in the event of a loss of coolant accident. The paak drywell pressure would be about 41 psic, which uould rapidly reduce to 25 psig within 10 seconds follow-ing the pipe break.
Following the pipe break, the suppression chsmber pressure' rises to 25 psig within 10 seconds, equalizes with drywell pressure and thereafter rapidly decays with the dry-well pressure decay. See Sect;on 5.2 3 FSAR.
The design pressure of the drywell and absorption chrenber is 56 psig. See Section 5.2.3 FSAR.
The design leak rate is O.5%/ day at a pressure of 56 psig. As indicated above, the pressure resIsonse of the drywell and suppression chamber following an aceident would be the same after about 10 seconds. Based on the calculated centsinment pressure response discussed above, the

Also, Lase <1 on the primary containment pressure response and the fact that the drywell and suppression chamber function as a unit, the primary containment will be tested as a unit rather than the individual compo-nents separately.
