egrity, and other vital safety functions are maintained. e. One of these circuits shall be designed to be available within a few seconds following a loss-of-coolant accident. [The staff has designated this circuit as the “Immediate access circuit.” Since only one such circuit is required, the offsite power system need not meet the single failure criterion with respect to its immediate access function.] Provisions shall be included to minimize the probability of losing electric power from any of the remaining supplies as a result of, or coincident with, the loss of power generated by the nuclear power unit, the loss of power from the transmission network, or the loss of power from the onsite electric power supplies. f. Analyses (performed by the utility) must verify that the grid remains stable in event of loss of the nuclear unit generator, the largest other unit on the grid or the most critical transmission line. [There is no specific requirement for meeting single failure. However, overlapping requirement (a) above requires the offsite/onsite power systems to meet single failure on a system basis.] DRAFT Rev. 3 - April 1996 8.1-12 [This Page Intentionally Left Blank] SRP Draft Section 8.1 Attachment A - Proposed Changes in Order of Occurrence 8.1-13 DRAFT Rev. 3 - April 1996 Item numbers in the following table correspond to superscript numbers in the redline/strikeout copy of the draft SRP section.
