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.

Although the Security Cornerstone is included in the Reactor Oversight Process assessment program, the Commission has decided that specific information related to findings and performance indicators pertaining to the Security Cornerstone will not be publicly available to ensure that security information is not provided to a possible adversary. Other than the fact that a finding or performance indicator is Green or Greater-Than-Green, security related information will not be displayed on the public web page.
