s requirement from the design basis, if its peak ground acceleration (PGA) level is set at 1/3 or less of the SSE PGA. However, no SRP change is being implemented at this time due to Integrated Impact # 971. Additionally, rulemaking proposed in FR 52255 is expected to lead to amendments to 10CFR100 with regard to, among other items, seismic requirements. However, because said rulemaking is not yet final, no SRP change is being implemented at this time, due to Integrated Impact # 1222. 23. Editorial. Deleted "safe shutdown earthquake," as the acronym "SSE" had been previously defined in this SRP section. 24. Editorial. Deleted "operating basis earthquake," as the acronym "OBE" had been previously defined in this SRP section. 25. Editorial. Substituted the acronym SSC for "structure, system and component." This acronym was introduced at the beginning of this SRP section, as its use is consistent with other SRP sections. 26. Editorial. Substituted the acronym SSC for "structure, system and component." This acronym was introduced at the beginning of this SRP section, as its use is consistent with other SRP sections. 27. Editorial. Changed wording to be consistent with currently used citation format, which is used in other portions of this SRP. 28. Editorial. Substituted the acronym SSC for "structure, system and component." This acronym was introduced at the beginning of this SRP section, as its use is consistent with other SRP sections. 29. SRP-UDP Format Item, Reformat Changed the abbreviation "Ref." to "References" in the References, Editorial. parenthetical reference citation and matched reference number to updated sequence of references in the reference list. 30. SRP-UDP format item - Metrication, Replaced "cycles per second" with "Hz," which is the Federal Std 376B. unit symbol for "hertz." 31. Editorial. Substituted the acronym SSC for "structure, system and component." This acronym was introduced at the beginning of this SRP section, as its use is consistent
