API 000 LBB Piping Assessment

* Seismic Response Spectra Affects- Compare AP600 vs. AP1000 Response Spectra- Identify Maximum Increase Factor Based on Corresponding Peak

Acceleration- Maximum Ratio from Both Horizontal Directions

(North-South: X-direction, East-West: Y-direction)

* Pipe Line Diameter Affects- Compare AP1000 vs. AP600 Pipe Diameter (Do AP1000 / Do AP600)

- Estimated Thermal Stress Proportional to Pipe Diameter Increase- Estimated Seismic Stress Proportional to 1 / Pipe Diameter

Increase

* Material Strength Affects- Bounding Analysis Curves (BACs) Based on Code Minimum Values- Certified Material Test Reports (CMTR) Review for 169 Heats- Revised BACs Modified to Incorporate CMTR Data as Needed

* Leak Detection Rate Affects- Bounding Analysis Curves (BACs) Based on 0.50 gpm Leak Detection

Capability- Certified Material Test Reports (CMTR) Review for 169 Heats- Revised BACs Modified to Incorporate 0.25 Leak Detection Capability as

Needed

* Sample of Piping Assessment- Normal RHR Suction Line - 10" Pipe

- Seismic Response Spectra Increase

- Passive RHR Return Line - 10" Pipe to 14" Pipe


- Pipe Size Increase

- Passive Core Cooling Line CMT-B (East) - 8" pipe


- Modified BACs (CMTR Data / 0.25 gpm Leak Rate Detection)

- Pressurizer Safety- 6"
