DUANE ARNOLD ENERGY CENTER - NRC FOLLOW-UP INSPECTION
REPORT 05000331/2013010; PRELIMINARY WHITE FINDING
Dear Mr. Anderson:
This letter discusses the inspection conducted from April 8, 2013, through September 5, 2013,
for your Duane Arnold Energy Center. The purpose of the inspection was to follow-up on
unresolved item (URI)05000331/2013002-01, A Standby Diesel Generator Lube Oil Heat
Exchanger Gasket Failure, to review the stations root cause evaluation and past operability
review associated with the March 8, 2013, failure of the A standby diesel generator (SBDG)
lube oil heat exchanger gasket. The enclosed report documents the results of the follow-up
inspection, which were discussed on September 5, 2013, with you and other members of your
staff.
Based on the results of this inspection, the Nuclear Regulatory Commission (NRC) has
identified a finding that has been preliminarily determined to be a White finding of low to
moderate safety significance that will result in additional NRC inspection and potentially other
NRC action. As described in Section 1R12, the self-revealed finding involved the failure to
prescribe a work instruction of a type appropriate to the circumstances for the re-assembly of
the A SBDG lube oil heat exchanger. Specifically, the work instruction did not contain sufficient
detail and acceptance criteria, appropriate torque values, and operating experience information
to ensure the gasket was properly compressed.
The finding is not a current safety concern. On March 8-10, 2013, actions were completed to
replace, and properly install the gasket, and successfully demonstrate operability of the A
SBDG following testing. Your staff also performed an immediate extent-of-condition evaluation
to provide assurance that the B SBDG was not susceptible to a similar concern with the lube oil
heat exchanger.
Attachment 2 to the Inspection Report contains Sensitive
Unclassified Non-Safeguards Information. Upon separation
from Attachment 2 to the Inspection Report, the enclosed
Inspection Report, and Attachment 1 to the Inspection Report
are DECONTROLLED.

This finding was assessed based on the best available information, using the applicable
significance determination process (SDP). The basis for the NRCs preliminary significance
determination is described in the enclosed report. This finding is also an apparent violation of
NRC requirements and is being considered for escalated enforcement action in accordance with
NRC Enforcement Policy. The current Enforcement Policy is included on the NRCs website at
http://www.nrc.gov/about-nrc/regulatory/enforcement/enforce-pol.html.
In accordance with NRC Inspection Manual Chapter 0609, we intend to complete our evaluation
using the best available information and issue our final determination of safety significance
within 90 days of the date of this letter. The SDP encourages an open dialogue between the
NRC staff and the licensee; however, the dialogue should not impact the timeliness of the staffs
final determination.
Before we make a final decision on this matter, we are providing you with an opportunity
to (1) attend a Regulatory Conference where you can present to the NRC your perspective on
the facts and assumptions the NRC used to arrive at the finding and assess its significance or
(2) submit your position on the finding to the NRC in writing. If you request a Regulatory
Conference, it should be held within 30 days of the receipt of this letter, and we encourage you
to submit supporting documentation at least one week prior to the conference in an effort to
make the conference more efficient and effective. The focus of the Regulatory Conference is to
discuss the significance of the finding and not necessarily the root cause(s) or corrective
action(s) associated with the finding. If a Regulatory Conference is held, it will be open for
public observation. If you decide to submit only a written response, such submittal should be
sent to the NRC within 30 days of your receipt of this letter. If you decline to request a
Regulatory Conference or submit a written response, you relinquish your right to appeal the final
Significance Determination Process determination, in that by not doing either, you fail to meet
the appeal requirements stated in the Prerequisite and Limitation sections of Attachment 2 of
Please contact Ms. Christine Lipa at 630-829-9703 and in writing within 10 days from the issue
date of this letter to notify the NRC of your intentions. If we have not heard from you within
10 days, we will continue with and finalize our significance determination and enforcement
decision. The final resolution of this matter will be conveyed in separate correspondence.
Because the NRC has not made a final determination in this matter, no Notice of Violation is
being issued for the inspection finding at this time. In addition, please be advised that the
number and characterization of the apparent violation described in the enclosed inspection
report may change as a result of further NRC review.
