3Q/10: Changed PRA Parameter(s). Update for change file: Version D of the Basis Document shows that the FVUAP values for Unit 2 RHRSW divisions 1 and 2 should be 3.90e-02 and 7.22e-02, respectively. However, the January Unit 2 Cooling Water Derivation Report shows that the FVUAP values for U2 RHRSW divisions 1 and 2 are still Version C values. Since the values in Version E of the Basis Document went into effect October 2010, the FVUAP values were overridden from January 2009 through September 2010 for U2 RHRSW Divisions 1 and 2 to be 3.90e-02 and 7.22e-02, as described in Version D of the Basis. This change did not affect the ???color??? of the indicator.
