- 3/5/80 Evening Shift until 3/7/80 Day Shift - Unit 1 Identification and Description of Occurrence:
Operations personnel, in reviewing Technical Specifications, determined a the plant had not performed SI-65 (which fulfills 3.9.2 and 3.9.5) during Core Alterations.
- Conditions Prior to Occurrence:
Unit 1 in Mode 6 following initial core loading. Upper internals installed and RCCA drag testing in progress.
Action specified in the Technical Specification Surveillance Requirements met due to inoperable equiptent. Describe.
N/A Apparent Cause of Occurrence:
l Misinterpretation of Technical Specification requirements.
