e. It states that seismic analyses are to 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. B. If there is a potential for explosive mixtures to exist, the MC is designed to withstand the effects of an explosion and instrumentation is provided to detect and annunciate the buildup of potentially explosive mixtures, dual instrumentation is provided to detect, annunciate, and effect control measures to prevent the buildup of potentially explosive mixtures, as outlined in SRP Section 11.3, subsection II, “Acceptance Criteria,” SRP Acceptance Criteria, Item 6. Technical Rationale The technical rationale for application of these acceptance criteria to the areas of review addressed by this SRP section is discussed in the following paragraphs: 1. 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 MC of BWRs during normal operation. In PWRs, radioactive materials may be deposited in the main condensers if there is a primary-to-secondary steam generator tube leak. Measures are taken to prevent uncontrolled release of these radioactive materials to the environment. 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 50, Appendix I.
