sis of design basis accident radiological consequences, guidance from SECY 93-087 (Reference 4) is applicable as follows: A seismic analysis should be performed to ensure that the condenser anchorages and the piping inlet nozzle to the condenser are capable of maintaining their structural integrity during and after an SSE.22 Technical Rationale: The technical rationale for application of the acceptance criterion for the main condensers is discussed in the following paragraphs.23 Compliance with GDC 60 requires that provisions be included in the nuclear power unit design to control suitably the release of radioactive materials in gaseous and liquid effluents during normal operation, including anticipated operational occurrences. GDC 60 is applicable to the design of the MC system because radioactive materials in both gaseous and liquid form are routinely deposited in the main condensers of BWRs during normal operation. In BWRs, the radioactivity in the main steam lines and the air ejector discharge are monitored to ensure that releases are suitably controlled. In PWRs, radioactive materials may be DRAFT Rev. 3 - April 1996 10.4.1-4 deposited in the main condensers if there is a primary-to-secondary steam generator tube leak. Measures are taken to detect primary-to-secondary leakage in PWRs by monitoring the radioactivity in the steam generator blowdown and in the air ejector discharge. Meeting these requirements provides a level of assurance that the release of radioactive materials in gaseous and liquid effluents from the main condensers during normal operation, including anticipated operational occurrences, is kept as low as is reasonably achievable, in accordance with 10 CFR Part 50.24 III. REVIEW PROCEDURES The procedures below are used during the construction permit (CP) review to determine that the design criteria and bases and the preliminary design meet the acceptance criteria given in subsection II. For the review of operating license (OL) applications, the
