In July, 2006 the NRC issued draft Regulatory Guide 1144 on how to apply environmental correction factors for fatigue. RIV000041 The regulatory guide said to use the equations in draft NUREG-6909, which was also issued for review about this time.
This sheet compares the calculations per RG-6906 and the previous guidance in Reg Guides 6583 and 5704.
Date Submitted: December 22, 2011 The result is a slightly higher Fen for CS, a slightly lower Fen for LAS, and a much lower Fen for SS.
