REQUEST FOR ADDITIONAL INFORMATION NINE MILE POINT UNIT 2 251.<
Provide pressure temperature limit curves that comply with the explicit closure flange material temperature requirements of the amended (May 27, 1983) Appendix G, 10 CFR 50, or Provide the analysis that shows that the closure flange region is less limiting than the beltline region.
Include as a minimum the following information:
a.
A description of the finite element analysis used to determine the stresses within the closure flange region.
b.
Indicate the peak bolt-up, pressure, and thermal stresses determined by the finite element analysis at the inside and outside surface locations of the flange to head and flange to shell junctions.
c.
Indicate how the bolt-up, pressure, and thermal stresses were combined to determine the maximum applied stress intensity factors.
d.
Indicate the flaw geometry used to calculate the maximum applied stress intensity factors.
e.
Indicate the maximum applied stress intensity factors for the flange to head and flange to shell junctions.

f.
Indicate the nondestructive examination methods that will be used during inservice examination to determine that the critical flaw
- size, which was used in determining the maximum applied stress intensity factors, is not within the flange to head and flange to shell junctions.
g.
Indicate whether the nondestructive examination methods identified in (f) have been evaluated to demonstrate that the examination methods are capable of locating and sizing flaws of the geometry used for calculating the maximum applied stress intensity factors.
Indicate the results of the evaluation.
251.5 Provide the lead factors for each surveillance capsule.
251.6 Provide revised pressure-temperature curves that allow for an increase in the RTNDT which will represent the predicted radiation damage for the affected time period of the curves.
