April 20, 2007Carolina Power & Light CompanyATTN:Mr. T. D. WaltVice PresidentH. B. Robinson Steam Electric Plant Unit 2
3581 West Entrance Road
Hartsville, SC 29550SUBJECT:NOTIFICATION OF H. B. ROBINSON NUCLEAR PLANT - COMPONENTDESIGN BASES INSPECTION - NRC INSPECTION REPORT
05000261/2007006Dear Mr. Walt:
The purpose of this letter is to notify you that the U.S. Nuclear Regulatory Commission (NRC)Region II staff will conduct a component design bases inspection at your H. B. Robinson Nuclear
Plant during the weeks of July 16 - 20, 2007, July 30 - August 3, 2007, and August 13 - 17,
2007. The inspection team will be led by Mr. Steven D. Rose, a Senior Reactor Inspector from
the NRC's Region II Office. This inspection will be conducted in accordance with the baseline
inspection procedure, Procedure 71111.21, Component Design Bases Inspection, issued June
22, 2006.The inspection will evaluate the capability of risk significant / low margin components to functionas designed and support proper system operation. The inspection will also include a review of
selected operator actions, operating experience, and modifications. During a telephone conversation on April 19, 2007, Mr. Rose confirmed with Mr. G. Sanders ofyour staff, arrangements for an information gathering site visit and the three-week onsite
inspection. The schedule is as follows: *Information gathering visit: Week of June 25 - 29, 2007*Onsite weeks: July 16 - 20, 2007, July 30 - August 3, 2007, and August 13 - 17, 2007.The purpose of the information gathering visit is to meet with members of your staff to identifyrisk-significant components and operator actions. Information and documentation needed to
support the inspection will also be identified. Mr. Walt Rogers, a Region II Senior Reactor
Analyst, may accompany Mr. Rose during the information gathering visit to review probabilistic
risk assessment data and identify risk significant components which will be examined during the
inspection.
CP&L 2The enclosure lists documents that will be needed prior to the information gathering visit. Please contact Mr. Rose prior to preparing copies of the materials listed in the enclosure and
provide this information to the Region II office by June 18, 2007. The inspectors will try to minimize your administrative burden by specifically identifying onlythose documents required for the inspection preparation. During the information gathering visit, the team leader will also discuss the following inspectionsupport administrative details: office space, supplemental documents requested to be made
available to the team in the Region II office prior to the inspection preparation week of
July 9 - 13, 2007; arrangements for site access; and the availability of knowledgeable plant
engineering and licensing personnel to serve as points of contact during the inspection.In accordance with 10 CFR 2.390 of the NRC's "Rules of Practice," a copy of this letter and itsenclosure will be available electronically for public inspection in the NRC Public DocumentRoom or from the Publicly Available Records (PARS) component of NRC's document system
(ADAMS). ADAMS is accessible from the NRC Web
site at http://www.nrc.gov/reading-rm/adams.html (the Public Electronic Reading Room).Thank you for your cooperation in this matter. If you have any questions regarding theinformation requested or the inspection, please contact Mr. Rose at (404) 562-4609 or me at
(404) 562-4876.Sincerely,/RA/L.M. Cain, Acting Branch ChiefEngineering Branch 1
