RIV000041 Date Submitted: December 22, 2011 In July, 2006 the NRC issued draft Regulatory Guide 1144 on how to apply environmental correction factors for fatigue.
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.
The result is a slightly higher Fen for CS, a slightly lower Fen for LAS, and a much lower Fen for SS.

RIV000041 Date Submitted: December 22, 2011 Note the new reg guide uses formula similar (but different) to NUREG-6717 without a term for ambient temperature.
