The Nuclear Regulatory Commission staff is increasing its oversight of Unit 1 at the St. Lucie nuclear power plant as a result of the number and type of unplanned shutdowns the plant has experienced.

The NRC review found that St. Lucie Unit 1 crossed the green-to-white threshold for Unplanned Scrams per 7,000 Critical Hours performance indicator.

This was due to one trip in the third quarter of 2011, one trip in the fourth quarter of 2011, and one trip in the first quarter of 2012.

In addition, the review identified that the Unplanned Scrams with Complications performance indicator also crossed the green-to-white threshold.

This was due to one complicated trip in the third quarter of 2011 and one complicated trip in the first quarter of 2012.

The NRC has placed St. Lucie Unit 1 in the Degraded Cornerstone Column of the Reactor Oversight Process Action Matrix beginning in the first quarter this year.

The NRC will conduct a supplemental inspection to provide assurance that the causes of the shutdowns are understood, that the extent of condition is identified, and ensure FPL’s corrective actions are sufficient.”
