NRC INSPECTION REPORT 050-00016/09-08(DNMS) - ENRICO FERMI UNIT 1

Dear Mr. Plona:

On September 16, 2009, the U.S. Nuclear Regulatory Commission (NRC) completed an inspection at the Enrico Fermi Unit 1 facility. The purpose of the inspection was to determine whether decommissioning activities were conducted safely and in accordance with NRC requirements. At the conclusion of the inspection on September 16, 2009, the NRC inspector discussed the findings with members of your staff.

The inspection consisted of an examination of activities at the facility as they relate to safety and compliance with the Commissions rules and regulations. Areas examined during the inspection included facility management and control, and radiological safety. Within these areas, the inspection consisted of a selective examination of procedures and representative records, field observations of activities in progress, and interviews with personnel.

Based on the results of this inspection, the NRC did not identify any violations.

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 the NRCs Agencywide Documents Access and Management System (ADAMS). ADAMS is accessible from the NRC Website at http://www.nrc.gov/reading-rm/adams.html.

Enclosure We will gladly discuss any questions you have concerning this inspection.

Sincerely,

/RA by George M. McCann acting for/

EXECUTIVE SUMMARY Enrico Fermi Unit 1 NRC Inspection Report 050-00016/09-08(DNMS)

This routine decommissioning inspection included reviews of facility management and control, and radiological safety.

Facility Management and Control The inspector determined that the licensees As-Low-As-Reasonably-Achievable (ALARA) Committee conducted its activities to ensure the ALARA goals are met.

(Section 1.1)

The inspector concluded that the conditions of the facility and equipment were adequate and capable of supporting the decommissioning activities. (Section 1.2)

Radiological Safety The inspector determined that the licensee continued to be effective in maintaining dose to workers well below the regulatory limits. (Section 2.1)

The inspector verified that the licensee maintained effluent releases well below the 10 CFR Part 20 release limits. (Section 2.2)

Report Details During the inspection period, the licensee was continuing decommissioning activities and preparing for the reactor vessel removal project.

1 Facility Management and Control 1.1 Organization, Management and Cost Controls (36801)

a. Inspection Scope The inspector attended the licensees As-Low-As-Reasonably-Achievable (ALARA)

Committee meeting to assess that the radiation doses to the workers is kept as low as reasonably achievable.

b. Observations and Findings During the inspection, the licensees ALARA Committee conducted a meeting to discuss the ALARA plan for the primary shield tank (PST) removal. During the meeting, the inspector observed the Chairman and members of the Committee effectively working together to ensure that the radiation doses to the workers are kept as low as reasonably achievable.

c. Conclusions The inspector determined that the licensees ALARA Committee conducted its activities to ensure the ALARA goals are met.

1.2 Decommissioning Performance and Status Review at Permanently Shut Down Reactors a. Inspection Scope (71801)

The inspector toured the plant to assess the working conditions of the decommissioning activities.

b. Observations and Findings During the inspection, contract workers involved in removal of graphite blocks from the PST, and in PST cutting wore appropriate protective equipment and followed established procedures. The licensee maintained the work location with adequate shielding, personnel barriers, and high efficiency particulate air (HEPA) filter exhaust systems, all to minimize worker doses. All radiological areas were adequately marked and posted.

c. Conclusions The inspector concluded that the conditions of the facility and equipment were adequate and capable of supporting the decommissioning activities.

2 Radiological Safety 2.1 Occupational Radiation Exposure (83750)

a. Inspection Scope The inspector reviewed the work request and ALARA reviews for the removal of the PST to evaluate the effectiveness of licensee controls to minimize the potential radiation exposure to the workers.

b. Observations and Findings Prior to PST removal, the licensee conducted the dose rate survey inside the reactor vessel and provided the survey data to the licensee contractor to calculate the dose rates in the PST pit and assess the total dose for the PST removal. The total estimated dose is about 18,000 millirem. Due to the additional engineering controls such as HEPA vacuum to control contamination and lead blankets for shielding, the actual dose will be much lower. The licensee plans to keep dose of each worker below the administrative limit of 1000 millirem.

The dose rates in the PST pit were continuously monitored during work evolutions to assure the dose rates were within expected criteria. If the dose rates are not within expected criteria then the job will be stopped and another dose assessment and ALARA evaluation will be made.

During the inspection, the progress of PST removal was approaching the reactor transition deck. The dose rates in the work area of the PST pit were within the expected criteria. The air sampling results did not indicate internal radiation hazards for the workers.

c. Conclusions The inspector determined that the licensee continued to be effective in maintaining dose to workers well below the regulatory limits.

2.2 Radioactive Waste Treatment, Effluent and Environmental Monitoring (84750)

a. Inspection Scope The inspector reviewed the analytical data of gaseous effluent releases for particulates and tritium from April 2009 to September 2009 to verify that the licensee met 10 CFR Part 20 effluent release limits.

b. Observations and Findings The licensee evaporated the liquid waste to reduce the volume of the waste for the disposal. Air sampling at the effluence release points did not indicate any positive results from particulates or tritium during the evaporation of the liquid waste.

c. Conclusions The inspector verified that the licensee maintained effluent releases well below the 10 CFR Part 20 release limits.

3 Exit Meeting The inspector presented the inspection results to members of the licensees staff at the conclusion of the inspection on September 16, 2009. The licensee did not identify any of the documents or processes reviewed by the inspector as proprietary.
