FIRST INTERIM REPORT Description of Condition Becnuse of misunderstanding between the Bellefonte design project and Bellefonte field forces, the field forces fabricated and installed cable tray hangers outside the tolerances allowed by the seismic analysis.

Interim Progress TVA field forces have been instructed to identify those supports that were modified outside the tolerances along with the deviation description, i

unless the deviation was covered by an approved Field Change Request. This information will be reanalyzed by TVA on a case-by-case basis. Any mooification required to ensure aeismic qualification will be made.
