Birmingham, AL 35201-1295SUBJECT:NOTIFICATION OF EDWIN I. HATCH NUCLEAR PLANT COMPONENTDESIGN BASES INSPECTION - NRC INSPECTION REPORT05000321/2006007 AND 05000366/2006007Dear Mr. Summer:

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 Edwin I. HatchNuclear Plant during the weeks of June 12-16, 2006, June 26-30, 2006, and July 10-14, 2006. The inspection team will be led by Mr. George Hopper, a Senior Reactor Inspector from theNRC's Region II Office. This inspection will be conducted in accordance with the baselineinspection procedure, Procedure 71111.21, Component Design Bases Inspection, issued

December 2, 2005.The inspection will evaluate the c

apability of risk significant / low margin components to functionas designed and support proper system operation. The inspection will also include a review ofselected operator actions, operating experience, and modifications. During a telephone conversation on March 2, 2006, Mr. Hopper confirmed with Ms. KathyUnderwood of your staff, arrangements for an information gathering site visit and the three-

week onsite inspection. The schedule is as follows:*Information gathering visit: Week of May 22-26, 2006.*Onsite weeks: June 12-16, 2006, June 26-30, 2006, and July 10-14, 2006. 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. Rudy Bernhard, a Region II Senior ReactorAnalyst, may accompany Mr. Hopper and the inspection team during the information gathering

visit to review probabilistic risk assessment data and identify risk significant components whichwill be examined during the inspection.The enclosure lists documents that will be needed prior to the information gathering visit.Please contact Mr. Hopper prior to preparing copies of the materials listed in the enclosure.

The inspectors will try to minimize your administrative burden by specifically identifying onlythose documents required for the inspection preparation.

SNC2During 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 May 28,

2006; arrangements for site access; and the availability of knowledgeable plant engineering andlicensing 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).

EnclosureINFORMATION REQUEST FOR HATCH NUCLEAR PLANTCOMPONENT DESIGN BASES INSPECTIONPlease provide the information electronically in ".pdf" files, Excel, or other searchable format onCDROM. The CDROM should be indexed and hyperlinked to facilitate ease of use. Information in "lists" should contain enough information to be easily understood to someone

who has a knowledge of boiling water reactor technology.1.Risk ranking of components from your site specific probabilistic safety analysis (PSA)sorted by Risk Achievement Worth (RAW) and sorted separately by Birnbaum

Importance. If possible, please provide a correlation between actual plant componentsin plain language, and RAW values.2.Provide a list of the top 500 cutsets from your PSA.

3.Risk ranking of operator actions from your site specific PSA sorted by RAW. Providecopies of your human reliability worksheets for these items.4.If you have an External Event or Fire PSA Model, provide the information requested inItems 1 and 2 for external events and fire.5.Any pre-existing evaluation or list of components and calculations with low designmargins (i.e., pumps closest to the design limit for flow or pressure, diesel generator

close to design required output, heat exchangers close to rated design heat removal,

MOV risk-margin rankings, etc.).6.A list of the last two years of operating experience evaluations, modifications, andcorrective actions sorted by component or system.7.Information of any common cause failure of components experienced in the last 5 yearsat your facility.
