to 9 safety from internal sources of SSC important to safety from, such as those caused by10 failure of tanks, vessels, and piping and backflow through floor drains. The effects of 11 piping failures are considered in SRP Section 3.6.1. The effects of flooding due to failure of tanks and vessels are reviewed within the context of this SRP section. Internal flooding caused by operation of the fire protection system should also be considered.12 Review Interfaces13 1. The ASBSPLB review for the underground drainage system and for flood protection 14 uses information provided by HGEBECGB reviews, as indicated below, to 15 assureensure that the integrated design of the underground drainage system is capable 16 of performing its safety function and that the flood protection utilized is compatible with the maximum flood elevation established for the plant site. Coordinated reviews are performed by other branches and the results used by the ASB to complete the overall evaluation of the flood protection. The coordinated reviews are as follows:17 a. The Hydrologic and Geotechnical Engineering Branch (HGEB)ECGB reviews 18 the underground drainage system as part of its primary review responsibility for SRP Section 2.4.13. b. The HGEBECGB also verifies the water elevations and coincident conditions 19 20 21 determined for the various conditions of site flooding, including and examines22 the adequacy of the type of flood protection utilized as part of its primary review responsibility for SRP Sections 2.4.1 through 2.4.14. c. The ECGB coordinates and performs the review of site parameters postulated for design in a standard design certification application as part of its primary review responsibility for SRP Section 2.3.6.23 Cd. The Structural Engineering Branch (SEB)ECGB determines the acceptability of 24 the design analyses, procedures, and criteria used for structures that must withstand the effects of the design basis flood as part of its primary review responsibility for
