REQUEST FOR ADDITIONAL INFORMATION REGARDING H. B. ROBINSON STEAM ELECTRIC PLANT, UNIT 2 LICENSE AMENDMENT REQUEST REGARDING TECHNICAL SPECIFICATIONS CHANGES TO SECTION 3.8.3, DIESEL FUEL OIL AND STARTING AIR. AND SECTION 3.8.S, DC SOURCES - SHUTDOWN DOCKET NO. SO-261 By letter to the Nuclear Regulatory Commission (NRC) dated January 20, 2011, (Agencywide Documents Access and Management System (ADAMS) Accession No. ML110310012) Carolina Power & Light Company, doing business as Progress Energy Carolinas, Inc., submitted a license amendment request to revise Technical Specifications (TS) Section 3.8.3, "Diesel Fuel Oil and Starting Air," and TS Section 3.8.S, "DC Sources - Shutdown," for the H. B. Robinson Steam Electric Plant, Unit No.2. The NRC staff has been reviewing the submittal and has determined that additional information is needed to complete its review.

1. The submittal states:

The proposed change to TS 3.8.3 revises the minimum air start receiver pressure as specified in Condition D from 100 psig to 1S0 psig. The current value of 100 pSig is non-conservative with the EDG vendor (Fairbanks Morse) recommendation of a minimum air pressure of 1S0 psig to ensure a reliable start.

Provide an analysis or calculation to justify the Fairbanks Morse recommendation that a minimum air pressure of 1S0 psig in the air start receiver will ensure a reliable start for each Robinson EDG.
