                SUPPLEMENTAL INSPECTION REPORT 05000282/2009015;
                05000306/2009015
Dear Mr. Schimmel:
On December 4, 2009, the U. S. Nuclear Regulatory Commission (NRC) completed a
supplemental inspection pursuant to Inspection Procedure 95001, Inspection for One or
Two White Inputs in a Strategic Performance Area, at your Prairie Island Nuclear Generating
Plant. The enclosed report documents the inspection results, which were discussed at the
combined exit and regulatory performance meeting conducted on December 4, 2009, with
Messrs. Bradley Sawatzke, Kevin Ryan and other members of your staff.
As required by the NRC Reactor Oversight Process Action Matrix, this supplemental
inspection was performed due to a White performance issue in the Public Radiation Safety
Cornerstone. Specifically, on May 6, 2009, the NRC issued its Final Significance Determination
and Notice of Violation (NRC Inspection Report 05000282/2009008 and 05000306/2009008) for
a White finding that involved the failure to properly prepare and ship a package containing
radioactive material in a manner that assured conformance with Department of Transportation
(DOT) radiation level limits specified in 49 CFR 173.441. The NRC staff was informed on
October 30, 2009, of your staffs readiness for this inspection.
The objectives of this supplemental inspection were to provide assurance that: (1) the root
causes and the contributing causes for the White performance issue were understood; (2) the
extent of condition and extent of cause were identified; and (3) corrective actions were or will be
sufficient to address and preclude repetition of the root and contributing causes. The inspection
consisted of examination of activities conducted under your license as they related to safety,
compliance with the Commission=s rules and regulations, and the conditions of your operating
license.
The inspectors determined that your staff performed a comprehensive evaluation of the White
finding using systematic techniques to determine the root and contributory causes of the
performance issue. Your staff=s evaluation identified that the root causes centered on poor
processes and procedure quality, and insufficient oversight including the lack of a risk
management process associated with the shipment program. In particular, your staff correctly
concluded that
 
M. Schimmel                                    -2-
the root causes involved programmatic issues and that the singular failure of a human
performance barrier was not a major contributor to the overall problems that led to the incident.
Corrective actions were implemented to address the identified causes and contributors, which
included significant modification to existing procedures along with the development of new
procedures. Also, the training and qualification program for staff involved in shipment activities
was enhanced. Additionally, an integrated risk management process was developed that
incorporates risk insights and thresholds to ensure the proper level of management engagement
in shipment related activities.
Although issues with aspects of your staff's extent of cause review for the White performance
issue were identified by our inspectors and documentation deficiencies associated with your
staff's root cause evaluation report were noted, based on the results of this inspection, no
findings of significance were identified.
Given your acceptable performance in addressing this performance issue, the White finding was
considered in assessing plant performance for a total of four quarters in accordance with the
guidance in IMC 0305, AOperating Reactor Assessment Program.@ Consequently, this issue
has been removed from consideration of future agency actions because four quarters has
elapsed following our input of the original finding in the assessment program (i.e., the end of the
fourth quarter 2009). Although this finding is removed from consideration in the Action Matrix,
Unit 2 remains in the regulatory response band (column 2) of the matrix based on a White
finding in the mitigating systems cornerstone assessed during the third quarter of 2009. We
have assessed Unit 1 as returning to the licensee response band (column 1) based on
successful completion of this supplemental inspection.
In accordance with 10 CFR 2.390 of the NRC's "Rules of Practice," a copy of this letter and
its enclosure will be available electronically for public inspection in the NRC Public Document
Room or from the Publicly Available Records (PARS) component of NRC's document system

Generating Plant, Units 1 & 2; Supplemental Inspection 95001.
This report covers an announced supplemental inspection by two regional health physics
inspectors. No findings were identified. The significance of most findings is indicated by their
color (Green, White, Yellow, Red) using Inspection Manual Chapter 0609, Significance
Determination Process (SDP). Cross-cutting aspects, as applicable, were determined using
Inspection Manual Chapter 0305, "Operating Reactor Assessment Program." Findings for
which the SDP does not apply may be Green or be assigned a severity level after NRC
management review. The NRCs program for overseeing the safe operation of commercial
nuclear power reactors is described in NUREG-1649, Reactor Oversight Process, Revision 4,
dated December 2006.
Cornerstone: Public Radiation Safety
The NRC staff performed this supplemental inspection in accordance with Inspection Procedure
(IP) 95001, Inspection for One or Two White Inputs in a Strategic Performance Area, to assess
the licensee=s evaluation associated with the failure to properly prepare and ship a package
containing radioactive material in October 2008, in a manner that assured conformance with the
Department of Transportation (DOT) radiation level limits specified in 49 CFR 173.441. The
NRC staff previously characterized this issue as having low to moderate safety significance
(White), as documented in NRC IR 05000282/2009008; 05000306/2009008. During this
supplemental inspection, the inspectors determined that the licensee performed a
comprehensive evaluation of the specific performance issue and that appropriate corrective
actions were taken to address each of the root and contributing causes. The licensee
determined that the performance issue had two root causes identified as: (1) inadequate
procedures and methods to successfully evaluate, package and ship radioactive materials in
accordance with NRC and DOT regulations; and (2) lack of a risk management process leading
to inadequate management oversight of the radioactive material shipment program.
Contributing causes were identified as: (1) ineffective incorporation of industry operating
experiences into the radioactive material shipment program; and (2) deficient training and
certification programs for radiation protection personnel that perform shipment related activities.
Corrective actions focused on development of new procedures and enhancement of existing
ones, improvements to the training and qualification program for staff involved in shipment
activities, and the development of an integrated risk management program to drive
management engagement and ensure proper oversight of potentially risk significant shipments.
Given the licensee=s acceptable performance in addressing the failure to evaluate, package and
transport a radioactive material shipment to satisfy DOT/NRC radiological limits that resulted in
the White finding, this public radiation safety cornerstone performance issue will not be held
open beyond the normal four quarters provided in accordance with the guidance in IMC 0305,
AOperating Reactor Assessment Program.@ The four quarters elapsed at the end of the fourth
quarter of 2009.
No findings of significance were identified.

4OA4 Supplemental Inspection (95001)
.01  Inspection Scope
    The NRC staff performed this supplemental inspection in accordance with IP 95001 to
    assess the licensees evaluation of a White finding, which affected the public radiation
    safety cornerstone in the radiation safety strategic performance area. The inspection
    objectives were to:
        *    provide assurance that the root and contributing causes of risk-significant issues
              were understood;
        *    provide assurance that the extent of condition and extent of cause of risk-
              significant issues were identified; and
        *    provide assurance that the licensees corrective actions for risk-significant issues
              were or will be sufficient to address the root and contributing causes to preclude
              repetition.
    The licensee entered the Regulatory Response Column of the NRCs Action Matrix in
    the first quarter of 2009 as a result of one inspection finding of low to moderate safety
    significance (White). Specifically, on October 29, 2008, the Prairie Island Nuclear
    Generating Plant shipped contaminated fuel sipping equipment to a vendor in
    Pennsylvania following decontamination of the equipment after its removal from the
    spent fuel pool. The equipment was surveyed, radiologically characterized, and
    packaged by both licensee and contractor staff and shipped as a surface contaminated
    object (SCO) in an open transport vehicle. Upon receipt by the vendor two-days later,
    package surface dose rates were found to exceed applicable DOT limits primarily due to
    a discrete radioactive particle that was embedded in the fuel sipping equipment. The
    fuel sipping equipment was found not to be properly braced or secured and shifted within
    the package during transport. A preliminary Yellow finding and an associated apparent
    violation were issued in NRC Inspection Report 05000282/2008009; 05000306/2008009.
    Based on the results of a radiological risk assessment employing both the public
    radiation safety and qualitative criteria significance determination processes, a final
    significance determination for a White finding and an associated Notice of Violation was
    issued by letter dated May 6, 2009.
    The licensee staff informed the NRC staff that they were ready for the supplemental
    inspection on October 30, 2009. The licensee performed a root cause evaluation (RCE),
    No. 01157726, Revision 2, to identify the root and contributing causes and other causal
    factors which allowed the risk-significant finding to occur, and to determine the
    organizational attributes that resulted in the White finding. The licensee also addressed
    safety culture in the RCE.
                                                2                                      Enclosure
 
      The inspectors reviewed the licensees RCE as well as other evaluations conducted in
      support and as a result of the RCE. The inspectors reviewed corrective actions that
      were taken or planned to address each of the identified causes and contributors. The
      inspectors also held discussions with licensee personnel to ensure that the root and
      contributing causes and the safety culture components were understood, and that
      corrective actions taken or planned were appropriate to address the causes and
      preclude repetition.
.02    Evaluation of Inspection Requirements
02.01 Problem Identification
    a. Inspection Procedure 95001 requires that the inspection staff determine that the
      licensees evaluation of the issue documents who identified the issue (i.e., licensee-
      identified, self-revealing, or NRC-identified) and the conditions under which the issue
      was identified.
      The excessive radiation levels on the package were revealed to the licensee by a vendor
      that identified the conditions upon package receipt at its facility in Pennsylvania. The
      elevated radiation levels were determined by the vendor through its routine package
      receipt survey practices. The inspectors verified that this information was documented
      in records maintained within the licensee's corrective action program including the
      licensees RCE.
    b. Inspection Procedure 95001 requires that the inspection staff determine that the
      licensees evaluation of the issue documents how long the issue existed and prior
      opportunities for identification.
      The DOT compliance issue existed for two-days while the shipment was en route from
      the Prairie Island facility to the vendors site in Pennsylvania.
      As part of its root cause evaluation, the licensee reviewed the specific circumstances
      associated with this incident to determine if opportunities existed for the problem to have
      been identified during the shipment preparation process before the shipment was
      released from the Prairie Island site. The licensee recognized that it missed
      opportunities to self-identify the issue because its radioactive material shipment program
      was not robust. Additionally, the licensee reviewed its corrective action program and
      internal/external operating experience databases and determined that prior opportunities
      to identify flaws in its radioactive material transportation program existed along with
      precursor incidents which the licensee failed to effectively address.
    c. Inspection Procedure 95001 requires that the inspection staff determine that the
      licensees evaluation documents the plant specific risk consequences, as applicable,
      and compliance concerns associated with the issue.
      A plant specific probabilistic risk-assessment was not applicable to this issue. However,
      the licensee evaluated the radiological risk to the public based on the actual
      circumstances of the incident including the potential for unnecessary dose to members
      of the public that could have come into contact with the shipment. Using risk insights
      provided in the significance determination process (SDP) for public radiation safety
      (Appendix D of Manual Chapter 0609) and the SDP that provides qualitative criteria
                                                  3                                      Enclosure
 
      (Appendix M of Manual Chapter 0609), the NRC concluded the performance issue
      represented a White finding primarily due to the limited actual radiological risk to the
      public. The NRCs final risk determination and finding were issued on May 6, 2009. The
      licensees RCE also documented that the finding associated with this issue was a
      violation of DOT and NRC requirements which limit package radiation levels to
      prescribed values.
  d. Findings
      No findings of significance were identified.
02.02 Root Cause, Extent of Condition, and Extent of Cause Evaluation
  a. Inspection Procedure 95001 requires that the inspection staff determine that the licensee
      evaluated the issue using a systematic methodology to identify the root and contributing
      causes.
      The licensee conducted a root cause analysis of the performance issue using fleet
      guidance document FG-PA-RCE-01, "Root Cause Evaluation Manual," Revision 14, and
      other implementing procedures. The licensee used the following systematic methods to
      complete the RCE:
          *  data gathering through interviews and document review;
          *  events and causal factor charting;
          *  task, barrier and change analyses; and
          *  why staircase analysis.
      The inspectors assessed the RCE report against the criteria in the licensee's guidance
      document and procedures, and determined that the evaluation followed the procedural
      requirements. Overall, the inspectors determined that the licensee evaluated the issue
      using systematic methodologies to adequately identify the root and contributing causes.
  b. Inspection Procedure 95001 requires that the inspection staff determine that the
      licensees RCE was conducted to a level of detail commensurate with the
      significance of the issue.
      The licensee's RCE employed various systematic methods to identify the causes of the
      performance issue as delineated above. Different methodologies were used to ensure
      the root and contributory causes were identified and aligned with those determined
      through alternate means. The licensees RCE determined the root causes of the
      performance issue were: (1) inadequate procedures and methods to successfully
      evaluate, package and ship radioactive materials in accordance with NRC and DOT
      regulations; and (2) the lack of a risk management process leading to inadequate
      management oversight of the radioactive material shipment program. In particular, the
      licensee's RCE correctly concluded that the root causes involved systemic issues with
      the radioactive material transportation program and that the failure of a human
                                                4                                        Enclosure
 
  performance barrier or other singular barrier was not a major contributor to the overall
  problems that led to the incident.
  Two contributing causes were identified as: (1) ineffective incorporation of industry
  operating experiences into the radioactive material transportation program; and (2)
  deficient training and certification programs for personnel that perform shipment related
  activities.
  The inspectors determined that the licensees evaluation was comprehensive and of
  sufficient scope and depth to reach the proper conclusions. As a result, the inspectors
  concluded that the root cause evaluation was conducted to a level of detail
  commensurate with the significance of the problem.
c. Inspection Procedure 95001 requires that the inspection staff determine that the
  licensees RCE included a consideration of prior occurrences of the issue and
  knowledge of operating experience (OE).
  As part of the RCE, the licensee reviewed its corrective action program and
  internal/external operating experience databases and determined that prior opportunities
  to identify flaws in its radioactive material transportation program existed along with
  precursor incidents which the licensee failed to effectively address. Previous corrective
  actions were limited in scope and focused on singular barriers such as worker
  performance rather than addressing broader programmatic flaws. Consequently,
  previous actions were not broadly effective. Moreover, the licensee determined there
  were numerous opportunities following the issuance of NRC Information Notice 88-101
  for Prairie Island to respond to industry trends associated with radioactive material
  shipments containing discrete radioactive particles. The licensee determined that
  industry operating experiences related to radioactive material shipments were not
  formally evaluated. Consequently, the licensee concluded that industry operating
  experiences had not been effectively incorporated into its shipment program and this
  failure was a contributing cause of the White performance issue.
  Based on the licensees detailed evaluation and conclusions, the inspectors determined
  that the licensees RCE included consideration of prior occurrences of the problem and
  knowledge of OE.
d. Inspection Procedure 95001 requires that the inspection staff determine that the
  licensees RCE addresses the extent of condition and extent of cause of the issue(s).
  The licensee=s evaluation considered the extent to which the actual condition (failure to
  meet shipment regulations) exists within other plant processes, equipment or human
  performance. The licensee's evaluation considered the potential for extent of condition
  within any of its hazardous material shipment programs including chemical and other
  non-radiological hazardous shipments. The licensee's extent of condition evaluation
  determined that no significant issues existed with other shipments of hazardous material
  based on a review of its corrective action program dating back to 2006.
  The licensees evaluation considered the extent to which the root causes of the
  radioactive material shipment problem impacted other plant processes, equipment or
  human performance. Five distinct areas of the licensee's hazardous material shipment
  program were evaluated in an effort to answer the following questions:
                                              5                                    Enclosure
 
        *  Environment - Do the causes impact other work environments/locations ?
        *  Equipment - Do the causes impact other equipment, systems or components?
        *  People - Do the causes impact other personnel or other human performance
            issues?
        *  Organization - Do the causes impact other crews, departments or organizations?
        *  Process - Are there similar processes or procedures that were impacted by the
            causes?
  To conduct its review, the licensee evaluated each of its hazardous material shipment
  programs in the five areas listed above to determine the actual or potential impact of the
  root causes. The review was performed for the licensee's warehouse and security
  organizations and the environmental, chemistry, and construction departments, all of
  which were involved in hazardous material shipment activities to varying degrees.
  These shipment programs were reviewed to assess procedure adequacy, to determine if
  the activities were adequately covered under a work management risk process and to
  assess the quality of the associated training and certification programs. Overall, the
  licensee identified no significant conditions adverse to quality associated with its other
  (non-radiological) hazardous material shipment programs; however, the licensee
  identified procedural deficiencies and process flaws which were being addressed
  through the corrective action program.
  The inspectors concluded that the licensees RCE addressed the extent of condition and
  the extent of cause for the White performance issue. However, the inspectors identified
  a deficiency with the validation method for one of the licensee's extent of cause
  conclusions. Specifically, the RCE validated that staff involved in non-radiological
  hazardous material shipments were trained and qualified based solely on interviews, but
  failed to validate that requirements were met through more effective means such as
  record reviews. A corrective action document was generated by the licensee to address
  the validation issue identified by the inspectors.
  Additionally, some of the conclusions in the extent of cause review were not supported in
  the RCE report. Specifically, the root cause report failed to document the basis for
  concluding that certain non-radiological hazardous material shipment procedures were
  adequate and that those procedures did not impact the root cause. Similarly, the report
  failed to document the basis for concluding that the "work environment" and "equipment"
  associated with the extent of cause review did not impact the root cause. The inspectors
  determined through interviews that the licensee reached its conclusions using sound
  methodologies, but failed to document how those conclusions were derived. Corrective
  action document was generated by the licensee to address RCE report deficiencies
  identified by the inspectors.
e. Inspection Procedure 95001 requires that the inspection staff determine that the
  licensees root cause, extent of condition, and extent of cause evaluations appropriately
  considered the safety culture components as described in IMC 0305.
                                              6                                      Enclosure
 
      The inspectors concluded that the safety culture aspects associated with the
      performance issue were appropriately considered in the licensee's RCE and included
      consideration whether a weakness in any safety culture component was a root cause or
      a significant contributing cause of the issue.
      The RCE determined that several safety culture components had impact on the
      performance issue and contributed to the White finding. Specifically, decision making
      (H.1), resources (H.2), work control and work practices (H.3 & H.4), and operating
      experience (P.2) all impacted the radioactive material shipment program and collectively
      led to the shipment incident. Each of these safety culture components had corrective
      actions to address the issues.
      The inspectors determined that the root cause report erroneously documented that the
      corrective action program (P.1) did not impact the performance issue. Nevertheless,
      actions had been taken by the licensee to address this safety culture component. The
      error was attributed to a documentation flaw in the final revision (Revision 2) of the RCE
      report.
  f. Findings
      No findings of significance were identified.
02.03 Corrective Actions
  a. Inspection Procedure 95001 requires that the inspection staff determine that: (1) the
      licensee specified appropriate corrective actions for each root and/or contributing cause;
      or (2) an evaluation that states no actions are necessary is adequate.
      The licensee's corrective actions focused on the programmatic problems associated with
      the identified root and contributing causes, and centered on the most risk significant
      activities to drive staff and management involvement. Those activities related to the
      radiological characterization of material to be shipped including the identification of
      discrete radioactive particles, the packaging of the material and its loading into shipping
      containers, the evaluation of radiological survey differences and resolution of anomalous
      radiological data, and delineating thresholds and levels of management engagement
      consistent with shipment risk.
      Corrective actions were developed to address the identified causes and the contributors
      so as to prevent recurrence of the performance issue. Corrective actions as
      documented in the root cause report included but were not limited to:
          *    Revisions to the suite of radioactive material shipment procedures to define,
              improve and enhance a variety of procedural attributes that impact shipment
              compliance.
          *    Revisions to radiation protection procedures to address methods to assist in the
              identification of discrete radioactive particles, package labeling and notification
              requirements should particles exist.
          *    Development of procedures for packaging of radioactive material.
                                                  7                                      Enclosure
 
        *  Development of a training and qualification program for shipping specialists and
            improvements in training for those involved in radioactive material shipment
            activities.
        *  Development of an integrated risk management assessment process that
            includes radioactive material shipment activities.
        *  Enhancements to the licensee's self-assessment program and audit activities for
            the radioactive material shipment program.
  To address the safety culture components related to human performance, the licensee
  had initiated a Human Performance Improvement Plan as part of a larger Performance
  Recovery Project. These plans address multiple aspects of human performance and are
  tracked in the corrective action program.
  The inspectors determined that the corrective actions were appropriate for the
  associated causes. However, the inspectors found that the RCE report failed to
  document all of the corrective actions which the licensee implemented to prevent
  recurrence. Specifically, several additional corrective actions were taken to address the
  causes developed but were not documented in the RCE report. These included actions
  to notify the shipment coordinator under certain circumstances, to identify
  inconsistencies in package versus equipment radiological conditions, and the measures
  to ensure staff are trained before involvement in certain shipping activities. A corrective
  action document was generated by the licensee to address inspector identified RCE
  report deficiencies.
b. Inspection Procedure 95001 requires that the inspection staff determine that the
  licensee prioritized corrective actions with consideration of risk significance and
  regulatory compliance.
  The licensee=s ceased all further radioactive material shipments following the vendor's
  notification to the licensee of the problem. The licensee dispatched members of the
  Prairie Island and corporate health physics staff to the vendor's site to facilitate its
  investigation. Various interim actions were taken before shipment activities
  recommenced which focused on radiological characterization and surveys, proper
  packaging to prevent migration of contaminants, and additional shipping specialist and
  management involvement in high risk shipments. Effectiveness reviews were performed
  following the development of corrective actions to ensure their adequacy.
  The inspectors determined that the corrective actions were prioritized with consideration
  of the risk significance and regulatory compliance.
c. Inspection Procedure 95001 requires that the inspection staff determine that the
  licensee established a schedule for implementing and completing the corrective actions.
  The licensee established adequate schedules for the completion of its corrective actions
  associated with the RCE. All actions associated specifically with shipment evaluation,
  packaging and preparation were completed in 2009, including effectiveness reviews to
  determine risk significant shipment readiness. The remaining actions were on schedule
  for completion in early 2010. The inspectors reviewed the completed corrective actions
                                              8                                        Enclosure
 
      and concluded that they had been implemented timely and effectively. No concerns
      were identified with the scheduling or completion of corrective actions.
  d. Inspection Procedure 95001 requires that the inspection staff determine that the
      licensee developed quantitative and/or qualitative measures of success for
      determining the effectiveness of the corrective actions to preclude repetition.
      The licensee developed means to validate the effectiveness of its corrective actions for
      the White performance issue. These were documented in the RCE and consisted of
      direct observations of risk significant shipment activities by industry peers, site
      management and the nuclear oversight organization, an external assessment of the
      radioactive material shipment program and a pending evaluation of recent operating
      experience reviews. Action items were entered into the corrective action program to
      ensure the effectiveness reviews were performed. The inspectors determined that
      quantitative and qualitative measures of success had been developed for determining
      the effectiveness of the corrective actions to preclude repetition.
  e. Inspection Procedure 95001 requires that the inspection staff determine that the
      licensees planned or taken corrective actions adequately address a Notice of Violation
      (NOV) that was the basis for the supplemental inspection, if applicable.
      The NRC issued its final significance determination and NOV ((05000282/2009008;
      05000306/2009008), Radioactive Material Shipment Package Radiation Levels
      Exceeded) to the licensee on May 6, 2009. The NRC concluded that information
      regarding the reason for the violation, the corrective actions taken and planned to correct
      the violation and prevent recurrence, and the date when full compliance was achieved,
      was already adequately addressed on the docket in Inspection Report No.
      05000282/2008009; 05000306/2008009. The NRC staff did not require a response from
      the licensee; therefore, this inspection requirement was not applicable.
  f. Findings
      No findings of significance were identified.
4OA6 Exit Meeting - Regulatory Performance Meeting Summary
      On December 4, 2009, the inspectors presented the inspection results to Messrs. B.
      Sawatzke, Site Director, and K. Ryan, Plant Manager, and other members of the Prairie
      Island and Excel Energy staffs, who acknowledged the conclusions. As part of this
      meeting, in accordance with IMC 0305, Section 10.01(a), Mr. K. O'Brien and other NRC
      staff discussed the issues related to the White finding that resulted in Prairie Island being
      placed in the Regulatory Response Column of the Action matrix. The discussions
      included the causes, corrective actions, extent of condition, and extent of cause
      associated with the White performance issue in the public radiation safety cornerstone.
      The inspectors asked the licensee if any of the material examined during the inspection
      should be considered proprietary. The licensee did not identify any information
      considered proprietary.

the root causes involved programmatic issues and that the singular failure of a human performance
barrier was not a major contributor to the overall problems that led to the incident. Corrective actions were
implemented to address the identified causes and contributors, which included significant modification to
existing procedures along with the development of new procedures. Also, the training and qualification
program for staff involved in shipment activities was enhanced. Additionally, an integrated risk
management process was developed that incorporates risk insights and thresholds to ensure the proper

Given your acceptable performance in addressing this performance issue, the White finding was only
considered in assessing plant performance for a total of four quarters in accordance with the guidance in
IMC 0305, AOperating Reactor Assessment Program.@ Consequently, this issue has been removed from
consideration of future agency actions because four quarters has elapsed following our input of the
original finding in the assessment program (i.e., the end of the fourth quarter 2009). Although this finding
is removed from consideration in the Action Matrix, Unit-2 remains in the regulatory response band
(column 2) of the matrix based on a White finding in the mitigating systems cornerstone assessed during

SUPPLEMENTAL INSPECTION REPORT 05000282/2009015;

05000306/2009015

Dear Mr. Schimmel:

On December 4, 2009, the U. S. Nuclear Regulatory Commission (NRC) completed a

supplemental inspection pursuant to Inspection Procedure 95001, Inspection for One or

Two White Inputs in a Strategic Performance Area, at your Prairie Island Nuclear Generating

Plant. The enclosed report documents the inspection results, which were discussed at the

combined exit and regulatory performance meeting conducted on December 4, 2009, with

Messrs. Bradley Sawatzke, Kevin Ryan and other members of your staff.

As required by the NRC Reactor Oversight Process Action Matrix, this supplemental

inspection was performed due to a White performance issue in the Public Radiation Safety

Cornerstone. Specifically, on May 6, 2009, the NRC issued its Final Significance Determination

and Notice of Violation (NRC Inspection Report 05000282/2009008 and 05000306/2009008) for

a White finding that involved the failure to properly prepare and ship a package containing

radioactive material in a manner that assured conformance with Department of Transportation

(DOT) radiation level limits specified in 49 CFR 173.441. The NRC staff was informed on

October 30, 2009, of your staffs readiness for this inspection.

The objectives of this supplemental inspection were to provide assurance that: (1) the root

causes and the contributing causes for the White performance issue were understood; (2) the

extent of condition and extent of cause were identified; and (3) corrective actions were or will be

sufficient to address and preclude repetition of the root and contributing causes. The inspection

consisted of examination of activities conducted under your license as they related to safety,

compliance with the Commission=s rules and regulations, and the conditions of your operating

license.

The inspectors determined that your staff performed a comprehensive evaluation of the White

finding using systematic techniques to determine the root and contributory causes of the

performance issue. Your staff=s evaluation identified that the root causes centered on poor

processes and procedure quality, and insufficient oversight including the lack of a risk

management process associated with the shipment program. In particular, your staff correctly

concluded that

M. Schimmel -2-

the root causes involved programmatic issues and that the singular failure of a human

performance barrier was not a major contributor to the overall problems that led to the incident.

Corrective actions were implemented to address the identified causes and contributors, which

included significant modification to existing procedures along with the development of new

procedures. Also, the training and qualification program for staff involved in shipment activities

was enhanced. Additionally, an integrated risk management process was developed that

incorporates risk insights and thresholds to ensure the proper level of management engagement

in shipment related activities.

Although issues with aspects of your staff's extent of cause review for the White performance

issue were identified by our inspectors and documentation deficiencies associated with your

staff's root cause evaluation report were noted, based on the results of this inspection, no

findings of significance were identified.

Given your acceptable performance in addressing this performance issue, the White finding was

considered in assessing plant performance for a total of four quarters in accordance with the

guidance in IMC 0305, AOperating Reactor Assessment Program.@ Consequently, this issue

has been removed from consideration of future agency actions because four quarters has

elapsed following our input of the original finding in the assessment program (i.e., the end of the

fourth quarter 2009). Although this finding is removed from consideration in the Action Matrix,

Unit 2 remains in the regulatory response band (column 2) of the matrix based on a White

finding in the mitigating systems cornerstone assessed during the third quarter of 2009. We

have assessed Unit 1 as returning to the licensee response band (column 1) based on

successful completion of this supplemental inspection.

In accordance with 10 CFR 2.390 of the NRC's "Rules of Practice," a copy of this letter and

its enclosure will be available electronically for public inspection in the NRC Public Document

Room or from the Publicly Available Records (PARS) component of NRC's document system

SUMMARY OF FINDINGS

IR 05000282/2009015; 05000306/2009015; 11/30/2009 - 12/04/2009; Prairie Island Nuclear

Generating Plant, Units 1 & 2; Supplemental Inspection 95001.

This report covers an announced supplemental inspection by two regional health physics

inspectors. No findings were identified. The significance of most findings is indicated by their

color (Green, White, Yellow, Red) using Inspection Manual Chapter 0609, Significance

Determination Process (SDP). Cross-cutting aspects, as applicable, were determined using

Inspection Manual Chapter 0305, "Operating Reactor Assessment Program." Findings for

which the SDP does not apply may be Green or be assigned a severity level after NRC

management review. The NRCs program for overseeing the safe operation of commercial

nuclear power reactors is described in NUREG-1649, Reactor Oversight Process, Revision 4,

dated December 2006.

Cornerstone: Public Radiation Safety

The NRC staff performed this supplemental inspection in accordance with Inspection Procedure (IP) 95001, Inspection for One or Two White Inputs in a Strategic Performance Area, to assess

the licensee=s evaluation associated with the failure to properly prepare and ship a package

containing radioactive material in October 2008, in a manner that assured conformance with the

Department of Transportation (DOT) radiation level limits specified in 49 CFR 173.441. The

NRC staff previously characterized this issue as having low to moderate safety significance

(White), as documented in NRC IR 05000282/2009008; 05000306/2009008. During this

supplemental inspection, the inspectors determined that the licensee performed a

comprehensive evaluation of the specific performance issue and that appropriate corrective

actions were taken to address each of the root and contributing causes. The licensee

determined that the performance issue had two root causes identified as: (1) inadequate

procedures and methods to successfully evaluate, package and ship radioactive materials in

accordance with NRC and DOT regulations; and (2) lack of a risk management process leading

to inadequate management oversight of the radioactive material shipment program.

Contributing causes were identified as: (1) ineffective incorporation of industry operating

experiences into the radioactive material shipment program; and (2) deficient training and

certification programs for radiation protection personnel that perform shipment related activities.

Corrective actions focused on development of new procedures and enhancement of existing

ones, improvements to the training and qualification program for staff involved in shipment

activities, and the development of an integrated risk management program to drive

management engagement and ensure proper oversight of potentially risk significant shipments.

Given the licensee=s acceptable performance in addressing the failure to evaluate, package and

transport a radioactive material shipment to satisfy DOT/NRC radiological limits that resulted in

the White finding, this public radiation safety cornerstone performance issue will not be held

open beyond the normal four quarters provided in accordance with the guidance in IMC 0305,

AOperating Reactor Assessment Program.@ The four quarters elapsed at the end of the fourth

quarter of 2009.

No findings of significance were identified.

REPORT DETAILS

4. OTHER ACTIVITIES

4OA4 Supplemental Inspection (95001)

.01 Inspection Scope

The NRC staff performed this supplemental inspection in accordance with IP 95001 to

assess the licensees evaluation of a White finding, which affected the public radiation

safety cornerstone in the radiation safety strategic performance area. The inspection

objectives were to:

  • provide assurance that the root and contributing causes of risk-significant issues

were understood;

  • provide assurance that the extent of condition and extent of cause of risk-

significant issues were identified; and

  • provide assurance that the licensees corrective actions for risk-significant issues

were or will be sufficient to address the root and contributing causes to preclude

repetition.

The licensee entered the Regulatory Response Column of the NRCs Action Matrix in

the first quarter of 2009 as a result of one inspection finding of low to moderate safety

significance (White). Specifically, on October 29, 2008, the Prairie Island Nuclear

Generating Plant shipped contaminated fuel sipping equipment to a vendor in

Pennsylvania following decontamination of the equipment after its removal from the

spent fuel pool. The equipment was surveyed, radiologically characterized, and

packaged by both licensee and contractor staff and shipped as a surface contaminated

object (SCO) in an open transport vehicle. Upon receipt by the vendor two-days later,

package surface dose rates were found to exceed applicable DOT limits primarily due to

a discrete radioactive particle that was embedded in the fuel sipping equipment. The

fuel sipping equipment was found not to be properly braced or secured and shifted within

the package during transport. A preliminary Yellow finding and an associated apparent

violation were issued in NRC Inspection Report 05000282/2008009; 05000306/2008009.

Based on the results of a radiological risk assessment employing both the public

radiation safety and qualitative criteria significance determination processes, a final

significance determination for a White finding and an associated Notice of Violation was

issued by letter dated May 6, 2009.

The licensee staff informed the NRC staff that they were ready for the supplemental

inspection on October 30, 2009. The licensee performed a root cause evaluation (RCE),

No. 01157726, Revision 2, to identify the root and contributing causes and other causal

factors which allowed the risk-significant finding to occur, and to determine the

organizational attributes that resulted in the White finding. The licensee also addressed

safety culture in the RCE.

2 Enclosure

The inspectors reviewed the licensees RCE as well as other evaluations conducted in

support and as a result of the RCE. The inspectors reviewed corrective actions that

were taken or planned to address each of the identified causes and contributors. The

inspectors also held discussions with licensee personnel to ensure that the root and

contributing causes and the safety culture components were understood, and that

corrective actions taken or planned were appropriate to address the causes and

preclude repetition.

.02 Evaluation of Inspection Requirements

02.01 Problem Identification

a. Inspection Procedure 95001 requires that the inspection staff determine that the

licensees evaluation of the issue documents who identified the issue (i.e., licensee-

identified, self-revealing, or NRC-identified) and the conditions under which the issue

was identified.

The excessive radiation levels on the package were revealed to the licensee by a vendor

that identified the conditions upon package receipt at its facility in Pennsylvania. The

elevated radiation levels were determined by the vendor through its routine package

receipt survey practices. The inspectors verified that this information was documented

in records maintained within the licensee's corrective action program including the

licensees RCE.

b. Inspection Procedure 95001 requires that the inspection staff determine that the

licensees evaluation of the issue documents how long the issue existed and prior

opportunities for identification.

The DOT compliance issue existed for two-days while the shipment was en route from

the Prairie Island facility to the vendors site in Pennsylvania.

As part of its root cause evaluation, the licensee reviewed the specific circumstances

associated with this incident to determine if opportunities existed for the problem to have

been identified during the shipment preparation process before the shipment was

released from the Prairie Island site. The licensee recognized that it missed

opportunities to self-identify the issue because its radioactive material shipment program

was not robust. Additionally, the licensee reviewed its corrective action program and

internal/external operating experience databases and determined that prior opportunities

to identify flaws in its radioactive material transportation program existed along with

precursor incidents which the licensee failed to effectively address.

c. Inspection Procedure 95001 requires that the inspection staff determine that the

licensees evaluation documents the plant specific risk consequences, as applicable,

and compliance concerns associated with the issue.

A plant specific probabilistic risk-assessment was not applicable to this issue. However,

the licensee evaluated the radiological risk to the public based on the actual

circumstances of the incident including the potential for unnecessary dose to members

of the public that could have come into contact with the shipment. Using risk insights

provided in the significance determination process (SDP) for public radiation safety

(Appendix D of Manual Chapter 0609) and the SDP that provides qualitative criteria

3 Enclosure

(Appendix M of Manual Chapter 0609), the NRC concluded the performance issue

represented a White finding primarily due to the limited actual radiological risk to the

public. The NRCs final risk determination and finding were issued on May 6, 2009. The

licensees RCE also documented that the finding associated with this issue was a

violation of DOT and NRC requirements which limit package radiation levels to

prescribed values.

d. Findings

No findings of significance were identified.

02.02 Root Cause, Extent of Condition, and Extent of Cause Evaluation

a. Inspection Procedure 95001 requires that the inspection staff determine that the licensee

evaluated the issue using a systematic methodology to identify the root and contributing

causes.

The licensee conducted a root cause analysis of the performance issue using fleet

guidance document FG-PA-RCE-01, "Root Cause Evaluation Manual," Revision 14, and

other implementing procedures. The licensee used the following systematic methods to

complete the RCE:

  • data gathering through interviews and document review;
  • events and causal factor charting;
  • task, barrier and change analyses; and
  • why staircase analysis.

The inspectors assessed the RCE report against the criteria in the licensee's guidance

document and procedures, and determined that the evaluation followed the procedural

requirements. Overall, the inspectors determined that the licensee evaluated the issue

using systematic methodologies to adequately identify the root and contributing causes.

b. Inspection Procedure 95001 requires that the inspection staff determine that the

licensees RCE was conducted to a level of detail commensurate with the

significance of the issue.

The licensee's RCE employed various systematic methods to identify the causes of the

performance issue as delineated above. Different methodologies were used to ensure

the root and contributory causes were identified and aligned with those determined

through alternate means. The licensees RCE determined the root causes of the

performance issue were: (1) inadequate procedures and methods to successfully

evaluate, package and ship radioactive materials in accordance with NRC and DOT

regulations; and (2) the lack of a risk management process leading to inadequate

management oversight of the radioactive material shipment program. In particular, the

licensee's RCE correctly concluded that the root causes involved systemic issues with

the radioactive material transportation program and that the failure of a human

4 Enclosure

performance barrier or other singular barrier was not a major contributor to the overall

problems that led to the incident.

Two contributing causes were identified as: (1) ineffective incorporation of industry

operating experiences into the radioactive material transportation program; and (2)

deficient training and certification programs for personnel that perform shipment related

activities.

The inspectors determined that the licensees evaluation was comprehensive and of

sufficient scope and depth to reach the proper conclusions. As a result, the inspectors

concluded that the root cause evaluation was conducted to a level of detail

commensurate with the significance of the problem.

c. Inspection Procedure 95001 requires that the inspection staff determine that the

licensees RCE included a consideration of prior occurrences of the issue and

knowledge of operating experience (OE).

As part of the RCE, the licensee reviewed its corrective action program and

internal/external operating experience databases and determined that prior opportunities

to identify flaws in its radioactive material transportation program existed along with

precursor incidents which the licensee failed to effectively address. Previous corrective

actions were limited in scope and focused on singular barriers such as worker

performance rather than addressing broader programmatic flaws. Consequently,

previous actions were not broadly effective. Moreover, the licensee determined there

were numerous opportunities following the issuance of NRC Information Notice 88-101

for Prairie Island to respond to industry trends associated with radioactive material

shipments containing discrete radioactive particles. The licensee determined that

industry operating experiences related to radioactive material shipments were not

formally evaluated. Consequently, the licensee concluded that industry operating

experiences had not been effectively incorporated into its shipment program and this

failure was a contributing cause of the White performance issue.

Based on the licensees detailed evaluation and conclusions, the inspectors determined

that the licensees RCE included consideration of prior occurrences of the problem and

knowledge of OE.

d. Inspection Procedure 95001 requires that the inspection staff determine that the

licensees RCE addresses the extent of condition and extent of cause of the issue(s).

The licensee=s evaluation considered the extent to which the actual condition (failure to

meet shipment regulations) exists within other plant processes, equipment or human

performance. The licensee's evaluation considered the potential for extent of condition

within any of its hazardous material shipment programs including chemical and other

non-radiological hazardous shipments. The licensee's extent of condition evaluation

determined that no significant issues existed with other shipments of hazardous material

based on a review of its corrective action program dating back to 2006.

The licensees evaluation considered the extent to which the root causes of the

radioactive material shipment problem impacted other plant processes, equipment or

human performance. Five distinct areas of the licensee's hazardous material shipment

program were evaluated in an effort to answer the following questions:

5 Enclosure

  • Environment - Do the causes impact other work environments/locations ?
  • Equipment - Do the causes impact other equipment, systems or components?
  • People - Do the causes impact other personnel or other human performance

issues?

  • Organization - Do the causes impact other crews, departments or organizations?
  • Process - Are there similar processes or procedures that were impacted by the

causes?

To conduct its review, the licensee evaluated each of its hazardous material shipment

programs in the five areas listed above to determine the actual or potential impact of the

root causes. The review was performed for the licensee's warehouse and security

organizations and the environmental, chemistry, and construction departments, all of

which were involved in hazardous material shipment activities to varying degrees.

These shipment programs were reviewed to assess procedure adequacy, to determine if

the activities were adequately covered under a work management risk process and to

assess the quality of the associated training and certification programs. Overall, the

licensee identified no significant conditions adverse to quality associated with its other

(non-radiological) hazardous material shipment programs; however, the licensee

identified procedural deficiencies and process flaws which were being addressed

through the corrective action program.

The inspectors concluded that the licensees RCE addressed the extent of condition and

the extent of cause for the White performance issue. However, the inspectors identified

a deficiency with the validation method for one of the licensee's extent of cause

conclusions. Specifically, the RCE validated that staff involved in non-radiological

hazardous material shipments were trained and qualified based solely on interviews, but

failed to validate that requirements were met through more effective means such as

record reviews. A corrective action document was generated by the licensee to address

the validation issue identified by the inspectors.

Additionally, some of the conclusions in the extent of cause review were not supported in

the RCE report. Specifically, the root cause report failed to document the basis for

concluding that certain non-radiological hazardous material shipment procedures were

adequate and that those procedures did not impact the root cause. Similarly, the report

failed to document the basis for concluding that the "work environment" and "equipment"

associated with the extent of cause review did not impact the root cause. The inspectors

determined through interviews that the licensee reached its conclusions using sound

methodologies, but failed to document how those conclusions were derived. Corrective

action document was generated by the licensee to address RCE report deficiencies

identified by the inspectors.

e. Inspection Procedure 95001 requires that the inspection staff determine that the

licensees root cause, extent of condition, and extent of cause evaluations appropriately

considered the safety culture components as described in IMC 0305.

6 Enclosure

The inspectors concluded that the safety culture aspects associated with the

performance issue were appropriately considered in the licensee's RCE and included

consideration whether a weakness in any safety culture component was a root cause or

a significant contributing cause of the issue.

The RCE determined that several safety culture components had impact on the

performance issue and contributed to the White finding. Specifically, decision making

(H.1), resources (H.2), work control and work practices (H.3 & H.4), and operating

experience (P.2) all impacted the radioactive material shipment program and collectively

led to the shipment incident. Each of these safety culture components had corrective

actions to address the issues.

The inspectors determined that the root cause report erroneously documented that the

corrective action program (P.1) did not impact the performance issue. Nevertheless,

actions had been taken by the licensee to address this safety culture component. The

error was attributed to a documentation flaw in the final revision (Revision 2) of the RCE

report.

f. Findings

No findings of significance were identified.

02.03 Corrective Actions

a. Inspection Procedure 95001 requires that the inspection staff determine that: (1) the

licensee specified appropriate corrective actions for each root and/or contributing cause;

or (2) an evaluation that states no actions are necessary is adequate.

The licensee's corrective actions focused on the programmatic problems associated with

the identified root and contributing causes, and centered on the most risk significant

activities to drive staff and management involvement. Those activities related to the

radiological characterization of material to be shipped including the identification of

discrete radioactive particles, the packaging of the material and its loading into shipping

containers, the evaluation of radiological survey differences and resolution of anomalous

radiological data, and delineating thresholds and levels of management engagement

consistent with shipment risk.

Corrective actions were developed to address the identified causes and the contributors

so as to prevent recurrence of the performance issue. Corrective actions as

documented in the root cause report included but were not limited to:

  • Revisions to the suite of radioactive material shipment procedures to define,

improve and enhance a variety of procedural attributes that impact shipment

compliance.

  • Revisions to radiation protection procedures to address methods to assist in the

identification of discrete radioactive particles, package labeling and notification

requirements should particles exist.

  • Development of procedures for packaging of radioactive material.

7 Enclosure

  • Development of a training and qualification program for shipping specialists and

improvements in training for those involved in radioactive material shipment

activities.

  • Development of an integrated risk management assessment process that

includes radioactive material shipment activities.

  • Enhancements to the licensee's self-assessment program and audit activities for

the radioactive material shipment program.

To address the safety culture components related to human performance, the licensee

had initiated a Human Performance Improvement Plan as part of a larger Performance

Recovery Project. These plans address multiple aspects of human performance and are

tracked in the corrective action program.

The inspectors determined that the corrective actions were appropriate for the

associated causes. However, the inspectors found that the RCE report failed to

document all of the corrective actions which the licensee implemented to prevent

recurrence. Specifically, several additional corrective actions were taken to address the

causes developed but were not documented in the RCE report. These included actions

to notify the shipment coordinator under certain circumstances, to identify

inconsistencies in package versus equipment radiological conditions, and the measures

to ensure staff are trained before involvement in certain shipping activities. A corrective

action document was generated by the licensee to address inspector identified RCE

report deficiencies.

b. Inspection Procedure 95001 requires that the inspection staff determine that the

licensee prioritized corrective actions with consideration of risk significance and

regulatory compliance.

The licensee=s ceased all further radioactive material shipments following the vendor's

notification to the licensee of the problem. The licensee dispatched members of the

Prairie Island and corporate health physics staff to the vendor's site to facilitate its

investigation. Various interim actions were taken before shipment activities

recommenced which focused on radiological characterization and surveys, proper

packaging to prevent migration of contaminants, and additional shipping specialist and

management involvement in high risk shipments. Effectiveness reviews were performed

following the development of corrective actions to ensure their adequacy.

The inspectors determined that the corrective actions were prioritized with consideration

of the risk significance and regulatory compliance.

c. Inspection Procedure 95001 requires that the inspection staff determine that the

licensee established a schedule for implementing and completing the corrective actions.

The licensee established adequate schedules for the completion of its corrective actions

associated with the RCE. All actions associated specifically with shipment evaluation,

packaging and preparation were completed in 2009, including effectiveness reviews to

determine risk significant shipment readiness. The remaining actions were on schedule

for completion in early 2010. The inspectors reviewed the completed corrective actions

8 Enclosure

and concluded that they had been implemented timely and effectively. No concerns

were identified with the scheduling or completion of corrective actions.

d. Inspection Procedure 95001 requires that the inspection staff determine that the

licensee developed quantitative and/or qualitative measures of success for

determining the effectiveness of the corrective actions to preclude repetition.

The licensee developed means to validate the effectiveness of its corrective actions for

the White performance issue. These were documented in the RCE and consisted of

direct observations of risk significant shipment activities by industry peers, site

management and the nuclear oversight organization, an external assessment of the

radioactive material shipment program and a pending evaluation of recent operating

experience reviews. Action items were entered into the corrective action program to

ensure the effectiveness reviews were performed. The inspectors determined that

quantitative and qualitative measures of success had been developed for determining

the effectiveness of the corrective actions to preclude repetition.

e. Inspection Procedure 95001 requires that the inspection staff determine that the

licensees planned or taken corrective actions adequately address a Notice of Violation

(NOV) that was the basis for the supplemental inspection, if applicable.

The NRC issued its final significance determination and NOV ((05000282/2009008;

05000306/2009008), Radioactive Material Shipment Package Radiation Levels

Exceeded) to the licensee on May 6, 2009. The NRC concluded that information

regarding the reason for the violation, the corrective actions taken and planned to correct

the violation and prevent recurrence, and the date when full compliance was achieved,

was already adequately addressed on the docket in Inspection Report No.

05000282/2008009; 05000306/2008009. The NRC staff did not require a response from

the licensee; therefore, this inspection requirement was not applicable.

f. Findings

No findings of significance were identified.

4OA6 Exit Meeting - Regulatory Performance Meeting Summary

On December 4, 2009, the inspectors presented the inspection results to Messrs. B.

Sawatzke, Site Director, and K. Ryan, Plant Manager, and other members of the Prairie

Island and Excel Energy staffs, who acknowledged the conclusions. As part of this

meeting, in accordance with IMC 0305, Section 10.01(a), Mr. K. O'Brien and other NRC

staff discussed the issues related to the White finding that resulted in Prairie Island being

placed in the Regulatory Response Column of the Action matrix. The discussions

included the causes, corrective actions, extent of condition, and extent of cause

associated with the White performance issue in the public radiation safety cornerstone.

The inspectors asked the licensee if any of the material examined during the inspection

should be considered proprietary. The licensee did not identify any information

considered proprietary.

the root causes involved programmatic issues and that the singular failure of a human performance

barrier was not a major contributor to the overall problems that led to the incident. Corrective actions were

implemented to address the identified causes and contributors, which included significant modification to

existing procedures along with the development of new procedures. Also, the training and qualification

program for staff involved in shipment activities was enhanced. Additionally, an integrated risk

management process was developed that incorporates risk insights and thresholds to ensure the proper

level of management engagement in shipment related activities.

Although issues with aspects of your staff's extent of cause review for the White performance issue were

identified by our inspectors and documentation deficiencies associated with your staff's root cause

evaluation report were noted, based on the results of this inspection, no findings of significance were

identified.

Given your acceptable performance in addressing this performance issue, the White finding was only

considered in assessing plant performance for a total of four quarters in accordance with the guidance in

IMC 0305, AOperating Reactor Assessment Program.@ Consequently, this issue has been removed from

consideration of future agency actions because four quarters has elapsed following our input of the

original finding in the assessment program (i.e., the end of the fourth quarter 2009). Although this finding

is removed from consideration in the Action Matrix, Unit-2 remains in the regulatory response band

(column 2) of the matrix based on a White finding in the mitigating systems cornerstone assessed during

the third quarter of 2009.
