Revision History Revision 1

EPS-GW-GL-700 of 30 Revision 1

This document has been revised to include changes to our standard design that are a result of Westinghouse design finalization reviews and changes committed to US NRC resulting from their review. The NRC changes are those changes identified as of September 2009 and reflect the proposed revision 18 to the US DCD that will be submitted mid 2010. In addition, this European DCD revision includes specific changes requested for a European AP1000. These changes include adding additional redundancy and separation to the AP1000 standard Normal Residual Heat Removal System, Component Cooling Water System, Service Water System, Spent Fuel Cooling, increasing of power of Main feedwater pumps from 3 pumps @ 33.33% to 3 pumps at 50% and a change of Reactor Coolant Pump vendor.

Table 6.4-1 Section 9.3.2.2.2 Section 9.3.2.2.3

Revised table "ONSITE CHEMICALS" to indicate that hydrogen is stored onsite in both liquid and gas phases. The table indicates only gas at this time. SNC-AA - If we refer to a commitment from WEC in a response (See Note that DCD Table 6.4-1 is expected to be revised by Westinghouse to include the line item for hydrogen in the liquid state), I think we need something more firm or definitive to allow NRC to track the change. Do we have an RAI response number, WEC letter number for a voluntary response or other that would allow us to identify it as a unique DCD change number for NRC? Additionally, if this wording stays intact, should say "to be revised".

10 CFR 52.63 Justification: (v) Is necessary to correct material errors in the certification information PI-014 COLA Review Process-12/8/08; WEC to address.
