Optimize Application Process o Identify issues where application process can be optimized o

Quality COLA - Level of Detail; Follow DG-1145 &

SRP o]

Early discussion on issues o]

RAI responses submitted quickly o Discuss issues, options, and resolutions with NRC Staff in public meetings 22

Example Issue: Fuel Selection o GE P8x8R fuel used in certified design (8 x 8)

No longer manufactured No longer supported o GE14 fuel (10x

10) currently available but very likely will not be the actual fuel used (we will use fuel design circa 2011) 23

Example Issue: Fuel Selection o Changing COLA fr "8% of FSAR and om GE P8x8R to GE 12 LTRs 14 impacts o Most work from GE P8x8R to GE14 must be redone when GEx is selected, and license amendments performed circa 2012 o Changing COLA from GE P8x8R to GE14 expends resources with little value 24

Example Issue: Fuel Selection o Potential resolution:

Use GE P8x8R fuel - no DCD departures for fuel related-issues o1 No departures from DCD Chapters 4, 12, 15, 19 for fuel-related issues at this time o

No departures from DCD subsections 1C, 2.3.2.9, 2.3.2.10, 2A, 31, 5.2.2, 6.3, and 11.1 for fuel related issues at this time o]

Deferred LTR submittals for fuel-related issues Commit in COLA submittal letter to submit standard fuel change amendment o Benefit: No duplicated NRC review and no wasted STPNOC & NRC resources 25

Permits and Authorizations o Developing permit schedules o Meet with applicable agencies in 4Q06 o Begin application process in 1Q07 o Anticipate involvement of 10 agencies, 23 permits and authorizations involving 26

Anticipated Interactions o

NRC to observe site boring work o Continue periodic meetings with next meeting early December o Expect NRC public meeting at site in early 2007 27

o Established PDRB

  • ] Charter Two meetings Scheduled to complete review identified Tier 1, Tier 2*,

and significant Tier 2 issues by 12/31/06 39

Potential Design Changes 0 Tier 1 Changes:

RCIC Weir Turbine Pump [improves reliability]

STP Flood Level [site requirement]

Hydrogen Recombiner Removal [Industry standard]

Eliminate MSL Rad Monitor Scram & MSIV Closure

[improves reliability/safety]

  • ] 110.% Bypass Capability [improves reliability]

40

Potential Design Changes o Tier 2* Changes:

n Fuel m ACI 349 - 1990 edition m Fiber Optic Links (Not formal ANSI FDDI Standard) o Significant Tier 2 Changes o Other Tier 2 changes will be evaluated using process "similar to 50.59" Appendix A to Part 52 using the criteria in 41

PDRB Reviewed Changes o Removal of SCRAM and MSIV automatic closure on MSLRM alarm o Weir-type turbine RCIC pump in turbine pump o 110% Bypass Capability lieu of Terry o Provide two 2% RWCU pumps instead of two 1%/

RWCU pumps o Medium voltage electrical distribution 0 Control building addition 42
