NRC 2006 Assessment Results Millstone

 Licensee Response Column for Unit 2 and Unit 3 at the end of 2006

 Unit 2 had a White Performance Indicator for the first three quarters.

- Unplanned Scrams with Loss of Normal Heat Removal

- NRC completed Supplemental Inspection (September 2006)

- PI returned to Green in 4th Quarter 15

NRC 2006 Inspection Results Millstone Inspection Findings

- 8 Findings of very low safety significance (Green) at Unit 2

- 8 Findings of very low safety significance (Green) at Unit 3

- 1 Finding of very low safety significance (Green) common to both units 16

NRC 2006 Inspection Results Millstone Common Theme Evaluation Identified five findings with a common theme in the area of problem identification and resolution (specifically, quality of operability determinations).

Reviewed Millstones corrective actions.

Concluded that Millstones actions are acceptable in scope, timeliness, and effectiveness to address these issues.

As a result, no substantive cross-cutting issue was identified.
