Licensee Comments:
1Q/07: A forced override of the Train A FVUAP CDE data was performed to correct a typographical error made during the 4Q/2006 PSA model update data entry. The incorrect value of 1.4303 was corrected to 1.43E-03.
4Q/06: Unit 1 EAC train A FVUAP value was corrected. The September 06 MSPI Basis Document update value of 1.43E-03 was incorrectly entered as 1.4303 (no exponent). This value was corrected on February 8, 2007.
