PLANT STATUS

Unit 3 began the inspection period at rated thermal power and remained at or near rated

thermal power for the inspection period.

INSPECTION SCOPES

Inspections were conducted using the appropriate portions of the inspection procedures (IPs) in

effect at the beginning of the inspection unless otherwise noted. Currently approved IPs with

their attached revision histories are located on the public website at http://www.nrc.gov/reading-

rm/doc-collections/insp-manual/inspection-procedure/index.html. Samples were declared

Program - Operations Phase. The inspectors performed activities described in IMC 2515,

Appendix D, Plant Status, observed risk significant activities, and completed on-site portions of

IPs. The inspectors reviewed selected procedures and records, observed activities, and

interviewed personnel to assess licensee performance and compliance with Commission rules

and regulations, license conditions, site procedures, and standards.
