SUBJECT:

DUANE ARNOLD ENERGY CENTER NRC SUPPLEMENTAL INSPECTION REPORT 05000331/2010405(DRS)

Dear Mr. Costanzo:

On May 13, 2010, the U. S. Nuclear Regulatory Commission (NRC) completed a supplemental inspection at your Duane Arnold Energy Center. The inspection examined activities conducted under your license as they relate to safety and compliance with the Commissions rules and regulations, and with the conditions of your license. The enclosed inspection report documents the inspection results, which were discussed at the exit meeting on May 13, 2010, with Mr. Byrne and other members of your staff. The NRC was informed of your readiness for the inspection on March 4, 2010.

As required by the NRC Reactor Oversight Process Action Matrix, this supplemental inspection was conducted to provide assurance that the root causes and contributing causes of the events resulting in a Greater than Green finding were understood, to independently assess the extent of condition and extent of cause, and to provide assurance that the corrective actions for significant performance issues were sufficient to address the root causes and contributing causes, and to prevent recurrence. The inspection consisted of plant walkdowns, a selected examination of representative records, observation of a limited scope tactical drill, observation of tabletop exercises, and interviews with personnel.

Based on the results of this supplemental inspection, no findings of significance were identified.

Enclosure contains Sensitive Unclassified Non-Safeguards Information. When separated from enclosure, this transmittal document is decontrolled. In accordance with 10 CFR 2.390 of the NRC's "Rules of Practice," a copy of this letter will be available electronically for public inspection in the NRC Public Document Room or from the Publicly Available Records System (PARS) component of NRC's Agencywide Documents Access and Management System (ADAMS), accessible from the NRC Web site at http://www.nrc.gov/reading-rm/adams.html (the Public Electronic Reading Room).

However, because of the security-related concerns contained in the enclosures, and in accordance with 10 CFR 2.390, a copy of this letters enclosure will not be available for public inspection.

Should you have any questions concerning this inspection, we will be pleased to discuss them with you.

Sincerely,

/RA/
