REQUEST FOR ADDITIONAL INFORMATION REGARDING PROPOSED AMENDMENT REQUEST FOR PROPOSED PRESSURE-TEMPERATURE CURVES PEACH BOTTOM ATOMIC POWER STATION, UNIT NO. 3 DOCKET NO. 50-277 1.
Please provide the adjusted reference temperature (ART) calculations for the Peach Bottom Atomic Power Station (Peach Bottom) Unit No. 3 beltline materials at the 1/4 T locations of the reactor pressure vessel based on the calculated neutron fluence values for these locations at 32 effective full-power years.
2.
Please provide the pressure-temperature (P-T) calculations over the entire temperature range for the unapproved P-T curves that were based on the KC equation in Section G-2110 of Appendix G to Section XI of the American Society of Mechanical Engineers, Boiler and Pressure Vessel Code, 2001 Edition. Provide the adjusted pressure value for each temperature value assessed, based on the limiting ART (limiting RTNDT) values for the Peach Bottom Unit No. 3 reactor vessel. Include all parameters used in the calculation (e.g., KIT values, temperature gradients across the wall, KIC values, and any margin included for pressure and/or temperature measurement uncertainty).
3.
Please confirm that the P-T curves (as provided in Peach Bottom Unit No. 3 Technical Specifications, Figure 3.4.9-1, Temperature/Pressure Limits for Inservice Hydrostatic and Inservice Leakage Tests, Figure 3.4.9-2, Temperature/Pressure Limits for Non-Nuclear Heatup and Cooldown Following a Shutdown, and Figure 3.4.9-3, Temperature/Pressure Limits for Criticality, which were approved in the Peach Bottom Amendment No. 250), are based on the 1/4 T location calculations for cooldown. Also, confirm that these curves are based on the limiting ART for the 1/4 T location of the vessel.
