The Cumulative value for "Number of Hours Reactor Was Critical", as stated in the March Monthly Operating Report was 168,872.6.

The correct value of 167,872.6 Hrs was reported to the INPO Consolidated Data Entry (CDE) program. The values input to CDE did not need revision.

This identification of the typographical error on Letter PLA-006052 is to ensure the hard copy record agrees the electronically transmitted data. 167,872.6 Hrs is the correct value for "Number of Hours Reactor Was Critical" as of the end of March 2006. The April report and subsequent reports will use this value when calculating future cumulative data for CDE and hard copy letters.Page 1 of 1 UNIT SHUTDOWNS DOCKET NO.UNIT DATE COMPLETED BY TELEPHONE 50-388 Two 05/15/2006 J.
