NRC plans baseline inspections at Davis-Besse in 2016 with one supplemental inspection associated with the White Performance Indicator NRC Inspection Activities Davis-Besse Nuclear Power Station DavisBesse Nuclear Power Station for 2016 PIs and Findings January 1 through December 31, 2016 2 resident inspectors on site - residents produced 1 White Performance Indicator (Scrams with Complications) in four quarterly inspection reports and walked first, third, and fourth quarters from scrams in the first and third through the plant daily quarters 17 other inspectors participated in various 15 Green/Severity Level IV findings which included:

Inadequate trend evaluation of 10 amp and 15 amp fuse inspections failures results in preventable fuse failures.

There were no major team inspections in 2016 Failure to address degraded turbine roof vents results in generator control cabinets water intrusion and a reactor trip Failure to provide appropriate work instructions for instrument seal assembly results in failure of some instrumentation designed for post-accident monitoring 4
