4.69. Table 3 presents a minimum set of recommended load combinations for a typical pressurized water reactor. Their applicability should be checked and the list modified or new lists created for specific applications, with account taken of the actual features of the design. For example, design specific load tables may be needed for penetrations, air locks or hatches. Load combinations for selected severe accidents are not included in the table (for a discussion of severe accidents, see Section 6). Table 3 also shows the recommended acceptance criteria for each load combination.

4.70. Loads resulting from an SL-2[6] earthquake [14] and design basis accidents should be combined, although one cannot realistically be a consequence of the other since the pressure boundary is designed to withstand an SL-2 earthquake.[7]
