MEMORANDUM TO: Kenneth Riemer, Chief
Branch 2
Division of Reactor Projects
FROM: Christine Lipa, Chief/RA/
Materials Control, ISFSI, and Decommissioning Branch
Division of Nuclear Materials Safety (DNMS)
SUBJECT: DUANE ARNOLD ENERGY CENTER
DNMS INPUT TO INTEGRATED REPORT NO.
Enclosed is a DNMS report input for the Duane Arnold Energy Center (DAEC) Integrated
Inspection Report No. 05000331/2008-005. This input provides the results of the on-site
inspection conducted on December 17 and 18, 2008, for the operation of an Independent Spent
Fuel Storage Facility Installation (ISFSI) at the DAEC. The inspection consisted of observations
and review of Technical Specification required surveillance activities and data associated with
the ISFSI. In addition, the inspection consisted of document review of ISFSI related corrective
action documents, radiological data, 10 CFR 72.48 screenings and evaluations, and emergency
action level documentation to verify compliance with the conditions of the general license.
The procedures for ISFSI inspections do not include procedure sample requirements.
Please include in report No. 05000331/2008-005 the docket number listed below associated
with dry fuel storage, Docket No. 072-00032.
I have reviewed this input and have determined it is ready for distribution to the licensee and
dissemination to the public.

.1 Operation of an Independent Spent Fuel Storage Installation (ISFSI) at Operating Plants
(60855.1)
a. Inspection Scope
The inspectors conducted a routine inspection of the Duane Arnold Energy Center
(DAEC) ISFSI program to verify compliance with the Certificate of Compliance (CoC),
Technical Specifications, and associated procedures. Specifically, the inspectors
observed and reviewed surveillance activities and historical data, performed a walkdown
of the ISFSI storage pad, and reviewed relevant Corrective Action Program (CAP)
documents, 10 CFR 72.48 screenings and evaluations, environmental and radiological
reports, and emergency action level (EAL) procedures.
The inspectors observed an Operations employee perform the required Technical
Specification surveillance activity to visually verify the horizontal storage module (HSM)
vent screens were clear of debris, and verified this activity was being performed in
accordance with Surveillance Test Procedure (STP) 3.0.0-01, Instrument Checks. The
inspectors observed that Operations was meeting the surveillance requirement but
performed the surveillance from the vehicle by driving next to the ISFSI fence. The
requirement did not specify how to perform the visual inspection of the vent screens, as
long as it could be verified that the vent screens are free of debris. The inspectors
questioned the licensee as to why the ISFSI storage pad was not entered to perform the
surveillance. The licensee wrote CAP 062404, which recommended a procedural
requirement for weekly inspection of the ISFSI storage pad and electrical building. In
addition, the inspectors performed a walkdown of the ISFSI and associated electrical
building to verify no combustibles were in the ISFSI, ISFSI Access Area, or in the
electrical building. The inspectors observed there was no obvious degradation of the
HSMs and the ISFSI and electrical building were generally clean and in good order.
The inspectors reviewed a selection of past Technical Specification surveillance records
since the last inspection in April 2005. The inspectors reviewed data from February
2008, April 2007, May 2006, and December 2005. Data reviewed included both the
Technical Specification required HSM vent screen visual inspection sign offs and HSM
temperature monitoring data. The inspectors reviewed Operating Instruction (OI) 581,
Horizontal Storage Module Temperature Monitoring and noted step (4), which states, in
part, that the following are some investigative Action Steps for HSM temperature
greater than 275F. One of the options is step (4) c. which, in part, states the licensee
can perform Independent verification of HSM Temperature with alternate temperature
measuring equipment The inspectors questioned the licensee on what alternate
measuring equipment and method would be used. The licensee did not have a method
proceduralized and CAP 062407 was written to revise OI 581 to include an alternate
method.
The inspectors reviewed CAPs relevant to ISFSI dating back to the last inspection in
April 2005. No deficiencies were identified in either the actions taken or the timeliness in
the documents reviewed. A list of CAPs reviewed can be found in the attached List of
2 Enclosure
Documents Reviewed section. In addition the inspectors reviewed the 2005, 2006, and
2007 Annual Radiological Environmental Operating Reports to verify 10 CFR 72.104
dose limits were not being exceeded and monitoring equipment is capable of performing
the required measurements. The inspectors also reviewed semi-annual radiation
surveys from June 2005 through October 2008 of the ISFSI to verify there were no
significant changes in dose rates in the area.
The inspectors reviewed 10 CFR 72.48 screening and evaluation documents to verify
any changes made were reviewed appropriately. All changes screened or evaluated
were conservative or administrative in nature. In addition, the inspectors reviewed the
EAL basis document for the ISFSI and associated abnormal operating procedures to
verify actions to be taken for the ISFSI during a design basis scenario were included.
Also, in the unlikely event that a HSM must be removed from service, the procedures to
transfer the dry shielded canister from the ISFSI to the refuel floor to be defueled were
reviewed to verify they could be performed.
b. Findings
No findings of significance were identified.
4OA6 Management Meetings
.2 Interim Exit Meetings
Interim exits were conducted for:
- Operation of an ISFSI at Operating Plants (60855.1) was discussed with Mr. R.
Anderson, Site Vice President, and other members of licensee management on
December 18, 2008.
