Licensee Comments:

6/11: Change reflects Maximum RCS Identified leakage value since 1Q2010. Unit 1 does not have a technical specification limit on identified leakage. Per NEI 99-02, the total leakage must be entered instead of the identified leakage. However, identified leakage was entered since 1Q2010. This was corrected in 3Q2011. This change has no impact on the color of the indicator.

3/11: Change reflects Maximum RCS Identified leakage value since 1Q2010. Unit 1 does not have a technical specification limit on identified leakage. Per NEI 99-02, the total leakage must be entered instead of the identified leakage. However, identified leakage was entered since 1Q2010. This was corrected in 3Q2011. This change has no impact on 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.
