Content:
above parameters can be tracked and recorded throughout the course of an accident. Item II.F.1 of NUREG-0737 and NUREG-0718 (References 24 and 25) , and Regulatory Guide 1.97, "Instrumentation For 32 Light-Water-Cooled Nuclear Power Plants to Assess Plant Conditions During and Following an Accident," should be followed. 7g. The minimum calculated containment pressure as determined by the LOTIC-2 Code (Ref. 26) should not be less than that used in the analysis of the emergency core cooling 33 system capability (see SRP Section 6.2.1.5, "Minimum Containment Pressure Analysis for Emergency Core Cooling System Performance Capability Studies"). h. In meeting the requirements of 10 CFR 50, §50.34(f)(3)(v)(A)(1), applicants subject to this article should evaluate an accident that releases hydrogen generated from a 100% fuel clad metal-water reaction. The evaluation should demonstrate that the appropriate article for service level C limits (considering pressure and dead load only), for either concrete or steel containments, from ASME Boiler Pressure Vessel Code, Section III, are met. In addition to the containment pressurization caused directly by this accident, the increase in pressure from either hydrogen burning in containment or initiation of the post-accident inerting system, if installed, should be analyzed. Unless specifically known, the post-accident inerting gas should be assumed to be carbon dioxide. 34 i. In meeting the requirements of 10 CFR 50, §50.34(f)(3)(v)(B)(1), applicants subject to this article should evaluate the containment design's capability to withstand full actuation of the post-accident inerting system, if installed. The peak pressure caused by inadvertent actuation of the post-accident inerting system should be less than the containment design pressure.35 Technical Rationale:36 The technical rationale for application of the above acceptance criteria to ice condenser containments is discussed in the following paragraphs: 1. GDC 16 requires the
