(1) . determine if containment air cooler cooling water systems are susceptible to either waterhammer or two-phase flow conditions during postulated accident conditions; (2) determine if piping systems that penetrate the containment are susceptible to l thermal expansion of fluid so that overpressurization of piping could occur.

Further, the Generic Letter requests that items one and two should be reviewed with respect to the scenarios referenced in the Generic Letter.

. A written summary report will be submitted to the NRC stating actions taken in response to the generic letter requested actions, conclusions reached relative to the susceptibility for waterhammer and two-phase flow in the containment air cooler 4 cooling water system and overpressurization of piping that penetrates containment,

! the basis for continued operation of affected systems and components, as applicable, and corrective actions, if any. We plan to submit the information within

120 days of the Generic Letter. However, should there be a valid reason determined j as a result of the ongoing evaluation to change the schedule, Waterford 3 would change this schedule, and we would apprise the NRC in writing of the reason and ,

revised schedule.-
