Using NB-3200 FEA As An Option To Stress Equations In NB-3600

  The ASME B&PV Section III Div.1 Code 2013 Edition is currently approved in 10CFR50.55(a). The 2013 edition, permits elastic FEA per NB-3200 in place of the stress equations of NB-3600, as follows: For pressure design – “NB-3611.2 Acceptability When Stresses Exceed Stress Limits. When the stresses as determined by the methods given in NB-3630 exceed […]
