AGENDA Meeting with Dominion Energy Kewaunee, Inc. (DEK)

Relating to License Amendment Request to Define Internal Flooding Analysis Criteria Kewuanee Power Station Docket No. 50-305 December 6, 2007 Time Topic Presenter 9:00 am Introduction NRC 9:15 am Status of Application NRC

• March 2006 License Amendment Request to redefine protection from flooding Narrows scope of protection to non-seismic piping Broadens definition of seismically-qualified piping Disregards flood protection for breaks in safety system piping

• NRC Requests for Additional Information (RAIs) in November 2006 and August 2007 to resolve concerns with scope Response expands position regarding seismically-qualified piping with inadequate basis Dismisses pre-licensing communication regarding flood protection for undefined breaks in safety system piping (e.g., service water and component cooling water) 10:00 am Flooding Scenarios and Mitigation DEK

• Extent of consideration of ruptures in non-seismic piping and spray/minor leaks in safety system piping

• Scope of protected systems (all Class I SSCs or only safe shutdown systems)

• End state for flooding initiated events (cold shutdown or hot shutdown)

• Mitigation factors (size of leak, operator action, holdup volumes, and drain paths) 11:30 am Lunch Break

Time Topic Presenter 1:00 pm Classification of potential flooding sources DEK

• Threshold for consideration as a potential flooding source

• Need to evaluate non Seismic Class I system

• Qualification of Class II and III* piping to Operational Basis Earthquake (OBE)

• Use of Uniform Building Code Zone 1 criteria as meeting OBE loading

• Sample analyses to cover full scope of pipe configurations and loading conditions

• Analysis considers inspection frequency and uncertainties in corrosion effects

• Class III piping as a flooding source

• Cast iron piping

• Safety factor for anchors

• Factoring in buckling 2:30 pm Comments and Questions NRC 2:45 pm Summary and Project Planning DEK/NRC 3:30 pm Adjourn
