By letter dated September 18, 1991, you requested an emergency Technical Specification (TS) Amendment related to Technical Specification Table 3.5-3, Item 3a, for the H. B. Robinson Steam Electric Station, Unit No. 2 (HBR-2).
Your proposed emergency TS amendment would add a footnote to the action statement. This proposed footnote allows a one-time-only exception for the remainder of Cycle 14 that allows power operation to continued until an outage of sufficient duration such that the surveillance test of TS Table 4.1-1, Item 32.a and 4.6.1.2 may be performed.
