SUBJECT: PALO VERDE NUCLEAR GENERATING STATION: INSPECTION
REPORT 05000528/2007012, 05000529/2007012, AND 05000530/2007012;
Dear Mr. Edington:
This letter discusses a finding that appears to have low-to-moderate safety significance. As
described in Section 5.7 of NRC Inspection Report 05000528/2007012, 05000529/2007012,
and 05000530/2007012, weaknesses in senior operators' ability to implement Emergency
Action Level 1-7 (potential loss of the reactor coolant system barrier) were identified by Palo
Verde Nuclear Generating Station during emergency response organization training for
operators, and the weaknesses were not corrected in a timely manner appropriate to the
significance of the knowledge deficiencies. Specifically, when evaluated during training
evolutions beginning in May 2007, a high percentage of senior operators incorrectly declared a
general emergency for simulated plant conditions that would require only a site area emergency
declaration, and corrective actions were not completed until October 2007.
The NRC determined that weaknesses associated with the senior operators' implementation of
Emergency Action Level 1-7 were identified on or about May 2, 2007, during Licensed Operator
Continuing Training, Cycle 3. Subsequently, the same weaknesses were observed during an
initial license examination in July 2007, and again during the subject NRC inspection in October
2007. The NRC determined that the weaknesses were not entered into the Palo Verde Nuclear
Generating Station's corrective action program until August 2007, and corrective actions to
address the weaknesses for on-watch senior operators were not implemented until October
2007. The NRC determined that corrective actions were implemented to correct the
weaknesses of those senior operators and senior operator candidates whose implementation of
Emergency Action Level 1-7 were specifically evaluated; however, actions to ensure the correct
implementation of Emergency Action Level 1-7 by all on-shift senior operators were not
performed in a timely manner when the weakness was identified (reference NRC Manual
Chapter 0609, Appendix B, Section 5.0).

This finding was assessed based on the best available information, including influential
assumptions, using the applicable significance determination process and was preliminarily
determined to be a White finding. The final resolution of this finding will convey the increment in
the importance to safety by assigning the corresponding color, i.e., (WHITE) a finding with some
increased importance to safety, which may require additional NRC inspection. The finding has
a low-to-moderate safety significance because the identified senior operator performance
weakness in implementing an emergency action level was associated with risk significant
planning standard 10 CFR 50.47(b)(4). Part 50.47(b)(4) is a risk significant planning standard
as described in Manual Chapter 0612, Appendix B, Section 2.0. The performance deficiency
constituted a planning standard functional failure because Palo Verde Nuclear Generating
Station failed to correct a performance deficiency associated with a risk significant planning
standard within a time appropriate to its significance.
The finding is also an apparent violation of NRC requirements 10 CFR 50.54(q) and 10 CFR Part 50, Appendix E, IV.F.2.g., and is being considered for escalated enforcement action in
accordance with the NRC Enforcement Policy. The current Enforcement Policy is available on
the NRCs Web site at www.nrc.gov/about-nrc/regulatory/enforcement/enforce-pol.html.
The apparent violation and underlying performance deficiency was discussed during a
conference call between Messrs. S. Bauer, Department Leader, Regulatory Affairs; E. O'Neil,
Department Leader, Emergency Preparedness; and R. Lantz, Chief, Operations Branch, NRC
Region IV, on January 9, 2008.
Before we make a final decision on this matter, we are providing you an opportunity, (1) to
present to the NRC at a Regulatory Conference your perspectives on the facts and assumptions
used by the NRC to arrive at the finding and 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. 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 receiving this letter.
Please contact Mr. Ryan E. Lantz, Chief, Operations Branch, Division of Reactor Safety, at
(817) 860-8159, within 10 business days of the 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 our significance
determination and enforcement decision, and you will be advised by separate correspondence
of the results of our deliberations on this matter.
Since the NRC has not made a final determination in this matter, no Notice of Violation is being
issued for this inspection finding at this time. In addition, please be advised that the number
and characterization of apparent violations described in the subject inspection report may
change as a result of further NRC review.
