UNITED STATES NUCLEAR REGULATORY COMMISSION ary 22, 2010

SUBJECT:

WILLIAM B. MCGUIRE NUCLEAR STATION - NRC EMERGENCY PREPAREDNESS INSPECTION REPORT 05000369/2009-501 AND 05000370/2009-501

Dear Mr. Hamilton:

On November 30, 2009, the U.S. Nuclear Regulatory Commission (NRC) completed an inspection at your William B. McGuire Nuclear Station, Units 1 and 2. The enclosed inspection report documents the inspection results, which were discussed on December 3, 2009, with Mr. S. Capps and other members of your staff.

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 inspectors reviewed selected procedures and records, observed activities, and interviewed personnel.

The report documents one NRC-identified finding of very low safety significance (Green). The finding was determined to involve a violation of NRC requirements. However, because of the very low safety significance and because it is entered into your corrective action program, the NRC is treating the finding as a non-cited violation (NCV) consistent with Section VI.A.1 of the NRC Enforcement Policy. If you contest the NCV in this report, you should provide a response within 30 days of the date of this inspection report, with the basis of your denial, to the Nuclear Regulatory Commission, ATTN.: Document Control Desk, Washington DC 20555-0001; with copies to the Regional Administrator, Region II; the Director, Office of Enforcement, United States Nuclear Regulatory Commission, Washington, DC 20555-0001; and the NRC Resident Inspector at William B. McGuire Nuclear Station.

Additionally, if you disagree with the characterization of any finding in this report, you should provide a response within 30 days of the date of this inspection report, with the basis for your disagreement, to the Regional Administrator, Region II, and the NRC Resident Inspector at the William B. McGuire Nuclear Station. The information you provide will be considered in accordance with Inspection Manual Chapter 0305.

DPC 2 In accordance with 10 CFR 2.390 of the NRC's "Rules of Practice," a copy of this letter, its enclosure, and your response, if any, 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 (ADAMS). ADAMS is accessible from the NRC Website at http://www.nrc.gov/reading-rm/adams.html (the Public Electronic Reading Room).

Sincerely,

SUMMARY OF FINDINGS

IR 05000369/2009-501 and 05000370/2009-501; August 17, 2009 - November 30, 2009;

William B. McGuire Nuclear Station, Units 1 and 2; Exercise Evaluation The report covered an announced inspection by two emergency preparedness inspectors, a senior project engineer, a senior emergency preparedness specialist, and a resident inspector.

One Green finding which is an NCV was identified. One finding was identified and determined to be a non-cited violation (NCV). The significance of most findings is indicated by their color (Green, White, Yellow, Red) using Inspection Manual Chapter (IMC) 0609, Significance Determination Process (SDP). The cross-cutting aspect was determined using IMC 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: Emergency Preparedness

Green.

The inspectors identified a Green NCV of 10 CFR50.47(b)(14) for failure to conduct a biennial exercise that was technically accurate and challenging, to the extent that it was not an adequate test of the plans, procedures, equipment, and implementation of the licensees emergency response capabilities. The licensee entered the deficiency into their corrective action program, as Problem Investigation Process (PIP) M-09-04560, M-09-05183, and M-09-05186, and planned to conduct a re-demonstration drill in May 2010.

This finding is greater than minor because it is associated with the Emergency Response Organization Performance attribute of the Emergency Preparedness Cornerstone, in that a biennial exercise that is not technically accurate and challenging is not an adequate test of the plans, procedures, equipment, and implementation of the licensees emergency response capabilities. The finding does not represent an immediate safety concern. This finding was evaluated using the Emergency Preparedness SDP and determined to be a finding of very low safety significance because there was no loss of planning standard function. The cause of the finding was directly related to the cross-cutting component of work practices in the area of Human Performance, because the licensee did not ensure the supervisory and management oversight of work activities supported nuclear safety

H.4(c). (Section 1EP1)

REACTOR SAFETY

Cornerstone: Emergency Preparedness

1EP1 Exercise Evaluation

a. Inspection Scope

Prior to the inspection activity, the inspectors conducted an in-office review of the exercise objectives and scenario submitted to the NRC to determine if the exercise would test major elements of the emergency plan as required by 10 CFR 50.47(b)(14).

This inspection activity represents one sample on a biennial cycle.

The onsite inspection consisted of the following review and assessment:

  • The adequacy of the licensees performance in the biennial exercise conducted on August 18, 2009, was reviewed and assessed regarding the implementation of the Risk Significant Planning Standards (RSPSs) in 10 CFR 50.47 (b)(4), (5), (9), and (10), which address emergency classification, offsite notification, radiological assessment, and protective action recommendations, respectively.
  • The overall adequacy of the licensees emergency response facilities with regard to NUREG-0696, Functional Criteria for Emergency Response Facilities and Emergency Plan commitments. The facilities assessed were the Control Room simulator, Technical Support Center (TSC), Operations Support Center (OSC) and Emergency Operations Facility (EOF).
  • Other performance areas besides the RSPS, such as the emergency response organizations (ERO) recognition of abnormal plant conditions, command and control, intra- and inter-facility communications, prioritization of mitigation activities, utilization of repair and field monitoring teams, interface with offsite agencies, and the overall implementation of the emergency plan and its implementing procedures.
  • The post-exercise critique process and the presentation to the licensee's senior management conducted on August 21, 2009, to evaluate the licensees self-assessment of its ERO performance during the exercise and to ensure compliance with 10 CFR 50 Appendix E.IV.F.2.g.

The off-site inspection consisted of the following review and assessment:

  • Review of all full-scale exercise scenarios, off-year exercises, integrated response facility drills, and exercise/drill documentation to determine if all program elements had been tested within a six-year period and that there was no scenario compromise for the present exercise.

The inspectors reviewed various documents which are listed in the Attachment to this report.

b. Findings

Introduction:

The inspectors identified a Green NCV of 10 CFR 50.47(b)(14). The biennial emergency exercise conducted on August 18, 2009, was not technically accurate and challenging, to the extent that it did not adequately test the plans, procedures, equipment, and implementation of the licensees emergency response capabilities as required by McGuires Emergency Plan, Revision 07-01.

Description:

On August 18, 2009, McGuire conducted a biennial exercise that was not technically accurate and challenging, to the extent that it did not adequately test the plans, procedures, equipment, and implementation of the licensees emergency response capabilities as required by McGuires Emergency Plan, Revision 07-01.

McGuires emergency plan, Section N.1.b, Exercise Scenario/Response, states in part that exercises will be designed to test the integrated capability of those involved and a major portion of the basic elements existing within the plans and organization. Section N.1.b also states in part that the exercise scenarios will be varied from year to year.

The inspectors identified examples of the similarities between the 2007 and 2009 exercise scenarios, scenario development issues, simulator fidelity issues, and issues with the administration of the scenario which demonstrated that the 2009 biennial exercise was not technically accurate and challenging.

1. The inspectors identified that there were significant similarities between McGuires August 16, 2009, exercise and the October 16, 2007, exercise.

The following are examples of the similarities:

  • The 2009 scenario timeline was adopted verbatim from the 2007 scenario.
  • The 2009 and 2007 exercises used the same Emergency Actions Levels (EALs) for both the Alert classification (EAL 4.6.A.1, Fire or explosion affecting the operability of plant safety systems required to establish or maintain safe shutdown) and Site Area Emergency classification (EAL 4.4.S.1, Failure of the reactor protective system instrumentation to complete or initiate an automatic reactor trip once a reactor Protective System setpoint has been exceeded and a manual trip was not successful).
  • Loss of the 1B feedwater pump turbine occurred due to oil leaks on the B train safety related trip solenoids at time 0920 on both exercises.

2. The inspectors identified issues in the scenario development that created

confusion among key ERO decision makers. The following are examples:

  • The ATWS at 50% power resulted in fuel damage sufficient to produce site boundary doses of 1 rem Total Effective Dose Equivalent and 5 rem thyroid. With no mechanism for clad damage in the scenario, there would be no fuel damage and no resultant site boundary doses. While the EOF staff thought there was fuel damage, other technical staff questioned how fuel damage could be possible.
  • The scenario development team did not recognize that a primary chemistry sample would be requested as a result of the transient and no Dose Equivalent Iodine (DEI) values were developed that would validate the whole body and thyroid doses at the site boundary.
  • The EOF radiological controller injected an incorrect (for simulated plant conditions) DEI value early in the scenario timeline when plant staff requested a reactor coolant sample. The controllers incorrect information early in the scenario resulted in significant confusion to players in the TSC and EOF and questioning of the DEI values provided.
  • The scenario development did not anticipate the Pressurizer Relief Tank rupturing.
  • Confusion in the EOF and a perceived time pressure for making an emergency declaration led to an early and incorrect General Emergency declaration.

3. A simulator fidelity issue resulted from the high unit vent iodine levels not

being correlated to the low iodine values in the Auxiliary Building and created confusion among key ERO decision makers.

4. The inspectors identified issues with administration of the scenario that

limited the challenge to the integrated capability of those involved. The following are examples:

  • The inspectors determined through interviews that McGuires routine exercise/drill practice limited the demonstration of radioprotective drugs (potassium iodine). Because the use of KI was not developed beyond the basic consideration of its use, the process documentation and subsequent evaluation could not be evaluated. Thus the scenario was limited in challenge.
  • The scenarios assembly and accountability required the capability to account for all individuals onsite within 30 minutes of the emergency and to account for all onsite individuals continuously thereafter. The licensee did not adequately demonstrate continuously maintaining accountability for onsite individuals.
Analysis:

The licensees conduct of a biennial emergency exercise on August 18, 2009, that was not technically accurate and challenging, to the extent that it did not adequately test the plans, procedures, equipment, and implementation of the licensees emergency response capabilities as required by McGuires Emergency Plan, Revision 07-01 was a performance deficiency. McGuires emergency plan, Section N.1.b Exercise Scenario/

Response, states in part that exercises will be designed to test the integrated capability of those involved and a major portion of the basic elements existing within the plans and organization. Section N.1.b also states in part that the exercise scenarios will be varied from year to year.

This finding was more than minor because it was associated with the Emergency Response Organization Performance attribute of the Emergency Preparedness Cornerstone, in that a biennial exercise that is not technically accurate and challenging is not an adequate test of the plans, procedures, equipment, and implementation of the licensees emergency response capabilities. The finding does not represent an immediate safety concern. This finding was evaluated using the Emergency Preparedness SDP and determined to be a finding of very low safety significance because there was no loss of planning standard function.

The cause of this finding was directly related to the cross-cutting component of work practices in the area of Human Performance, because the licensee did not ensure the supervisory and management oversight of work activities supported nuclear safety.

Specifically, the development and review of the scenario by EP supervision and the scenario development team failed to identify the inadequacies of the exercise H.4(c).

Enforcement:

10 CFR 50.47(b)(14) requires that periodic exercises are conducted to evaluate major portions of emergency response capabilities, periodic drills are conducted to develop and maintain key skills. Contrary to the above, the licensees 2009 biennial exercise conducted on August 18, 2009, failed to evaluate major portions of the licensees emergency response capabilities. The exercise was not an adequate test of the plans, procedures, equipment, and implementation of the licensees emergency response capabilities. Because this failure to comply with 10 CFR 50.47(b)(14) is of very low safety significance and has been entered into the licensees corrective action program, as Problem Investigation Process (PIP) M-09-04560, M-09-05183, and M-09-05186, and the licensee has determined a re-demonstration drill will be conducted in May 2010, the violation is being treated as an NCV, consistent with Section VI.A of the NRC Enforcement Policy: NCV 05000369, 370/2009501-01, Biennial exercise was not an adequate test.

1EP4 Emergency Action Level and Emergency Plan Changes

a. Inspection Scope

Since the last NRC inspection of this program area, revisions 08-01 and 09-01 of the McGuire Nuclear Station Emergency Plan were implemented. The licensee determined that in accordance with 10 CFR 50.54(q), the changes resulted in no decrease in the effectiveness of the Plan, and that the revised Plan continued to meet the requirements of 10 CFR 50.47(b) and Appendix E to 10 CFR Part 50. The inspectors conducted a sampling review of the implementing procedure changes made between October 1, 2008, and June 30, 2009, to evaluate for potential decreases in effectiveness of the Plan. However, this review was not documented in a Safety Evaluation Report and does not constitute formal NRC approval of the changes. Therefore, these changes remain subject to future NRC inspection in their entirety.

The inspection was conducted in accordance with NRC Inspection Procedure 71114, 04, AEmergency Action Level and Emergency Plan Changes.@ The applicable planning standard (PS), 10 CFR 50.47(b)(4) and its related 10 CFR 50, Appendix E requirements were used as reference criteria.

The inspectors reviewed various documents which are listed in the Attachment. This inspection activity satisfied one inspection sample for the emergency action level and emergency plan changes on an annual basis.

b. Findings

No findings of significance were identified.

OTHER ACTIVITIES

4OA1 Performance Indicator Verification

a. Inspection Scope

Cornerstone: Emergency Preparedness

The inspectors sampled licensee submittals for three Performance Indicators (PI) listed below. For each of the submittals reviewed, the inspectors reviewed the period from July 1, 2008 through June 30, 2009. To verify the accuracy of the PI data reported during that period, PI definitions and guidance contained in Nuclear Energy Institute (NEI) 99-02, ARegulatory Assessment Indicator Guideline,@ Revision 6, were used to verify the basis in reporting for each data element.

$ Emergency Response Organization Drill/Exercise Performance (DEP)

$ Emergency Response Organization Readiness (ERO)

$ Alert and Notification System Reliability (ANS)

The inspectors reviewed portions of the raw PI data developed from monthly performance indicator reports and discussed the methods for compiling and reporting the PIs with cognizant emergency preparedness personnel. The inspectors also independently screened drill and exercise opportunity evaluations, drill participation reports, and drill evaluations. Selected reported values were calculated to verify their accuracy. The inspectors compared graphical representations from the most recent PI report to the raw data to verify that the data was correctly reflected in the report.

Reviewed documents are listed in the Attachment.

b. Findings

No findings of significance were identified.
