255, the staff is developing the third proposed revision 2 to Regulatory Guide 1.12 as Draft Regulatory Guide DG-1033. 30. Integrated Impact #1417. Cited EPRI NP-5930 as an appropriate reference to be included in this SRP section. 31. SRP-UDP format item, Metrication The existing threshold of 0.3 g (standard acceleration policy implementation. of gravity) for changes in seismic instrumentation requirements was converted to 2.9 m/s using the 2 guidance of Federal Standard 376B. See enclosed conversion documentation.
