1) whether or not the actions requested will be completed, 2) whether or not the information requested will be provided to the NRC, and 3) whether or not these actions will be completed within the requested time period.
Accordingly, the District will determine if:
Containment air cooler cooling water systems are susceptible to either waterhammer or two-phase flow conditions during postulated accident conditions.
Piping systems that penetrate the containment are susceptible to thermal expansion of fluid so that overpressurization of piping could occur.
Within 120 days of the <ha of this generic letter, the District will inform the NRC of the conclusions reached as a n:sult of the above determinations. For affected systems, the submittal will describe the specific circumstances involved. In addition to conclusions reached, the District will i.iclude the basis for continued operability of affected systems and components, as applicab13, and a summary of corrective actions taken or planned.
