safety is maintained. Since containment plays a vital safety role, appropriate instrumentation, such as temperature and pressure, must be provided so that operators can verify containment is properly fulfilling its function. Regulatory Guide 1.97 provides specific criteria for the design of containment instrumentation which have been found acceptable by the NRC as fulfilling GDC 13. Meeting GDC 13 and the specific guidance of Regulatory Guide 1.97 will help ensure that containment accomplishes its mission of precluding the release of radioactivity to the environment. Branch Technical Position 7-10, “Guidance on Application of Regulatory Guide 1.97," provides the specific acceptance criteria to satisfy Regulatory Guide 1.97. 5. GDC 64 requires that the containment atmosphere be monitored for the release of radioactivity from normal operations, anticipated operational occurrences, and accidents. In order to ensure that the containment functions properly, operators must be aware of any radioactive releases within containment so that they can take appropriate manual action or monitor automatic action. Regulatory Guide 1.97 provides specific criteria for the design of containment instrumentation which have been found acceptable by the NRC as fulfilling GDC 64. Branch Technical Position 7-10, “Guidance on Application of Regulatory Guide 1.97," provides the specific acceptance criteria to satisfy Regulatory Guide 1.97. Meeting GDC 64 and the specific guidance of Regulatory Guide 1.97 will assist operators in ensuring that containment meets its safety function of preventing the release of radioactivity to the environment. 6. 10 CFR 50.34(f)(3)(v)(A)(1) requires that the containment be designed to withstand either hydrogen burning or initiation of the post-accident inerting system, if installed, during an accident that releases hydrogen from a 100% fuel clad metal-water reaction. During the accident at TMI-2, metal-water reactions generated hydrogen in excess of the
