ENCLOSURE Request For Additional Information Callaway/ Wolf Creek tECHANICAL ENGINEERING BRANCH 210.0 j
210.2 The applicant states that all circumferential breaks in the RCS piping are assumed to result in a limited separation such that the maximum flow area is less than a full break area. The applicant must provide the design information assumed for each location where limited break areas are postulated including gap size, restraint stiffness, blowdown force, and maximum restraint deflection. The results of the time-history analysis (if used) should include the break area vs. time and mass flux rate vs. time which were used to calculate the subcompartment pressurization.
In addition, all restraint locations on the RCS piping must be shown.
