Enclosure to NRC-11-0043 Page 2 ENRICO FERMI ATOMIC POWER PLANT, UNIT 1 ANNUAL REPORT JULY 1, 2010 THROUGH JUNE 30, 2011 1.0 PREFACE This report provides a summary of the activities performed and the results of the facility surveillance program of the Enrico Fermi Atomic Power Plant, Unit 1 Decommissioning Project, during the past twelve (12) months ending June 30, 2011.

In summary, required activities were conducted in accordance with the Operating License and Technical Specifications. Fermi 1 continued decommissioning activities with the removal of contaminated components and commencement of final status surveys to achieve license termination. Based on a review performed during this period, Detroit Edison has decided to return the project to a passive monitoring SAFSTOR status late in 2011.

2.0 SAFSTOR STATUS 2.1 Health Physics 2.1.1 Personnel Exposure From July 1, 2010 through June 30, 2011, all monitored Fermi 1 personnel wore Thermoluminescent Dosimeters (TLDs) as dosimetry of record. Electronic Dosimeters (EDs) were worn from July 1, 2010 through June 30, 2011 as secondary dosimetry at Fermi 1. All visitors were appropriately escorted and wore EDs as a minimum when entering all Radiologically Restricted Areas (RRA).

The cumulative whole body dose from activities associated with Fermi 1 was 21,889 millirem for this reporting period. This is based on TLD readings for the whole period except for July 2010, which is based on ED readings. Electronic dosimeter readings were used for July 2010, since TLD readings for the second quarter of 2010 overlapped through July.

2.2 Surveillance Program 2.2.1 Environmental Surveys No liquid radiological releases occurred during this period; therefore, environmental monitoring samples were not required.

2.2.2 Weekly Tests and Inspections SGeneral area - The Fermi 1 staff performed walk through and visual inspections as required by Technical Specifications. No issues were identified during the inspections.

Enclosure to NRC-11-0043 Page 3 2.2.3 Monthly Inspections

• Controlled Area Inspections - During the specified interval, Fermi 1 staff conducted visual inspections of the fences, gates, and doors and surveyed the sump water levels from the top access points of all active sumps. Only minor issues requiring replacement of sump pumps and a door seal were identified during the inspections.

2.2.4 Ouarterly Surveillances Radiological Surveys - The Radiation Protection technicians checked the Reactor Building and the Fuel and Repair Building (FARB) for presence of gamma radiation, as well as beta, gamma, and alpha contamination. There were no unexpected radiation readings detected. The results of the quarterly contamination surveys indicated general area walkways remain <500-dpm/100 cm2 beta/gamma and <20-dpm/100-cm2 alpha.

3.0 DECOMMISSIONING PROJECT The Fermi 1 Decommissioning Project continued during this period including equipment removal, decontamination, and commencement of final status surveys. Details are discussed below.

Based on a review performed this year, Detroit Edison has decided to return the project to a passive monitoring SAFSTOR status from the active final decontamination phase of SAFSTOR. Selected activities will be completed later this year prior to returning to passive SAFSTOR. Details are discussed in Reference 2.

The Fermi 1 staff collected groundwater monitoring well samples and installed five (5) new wells to obtain information for license termination planning. No radioactive isotopes were detected above background levels, with the exception of Radium (226 and 228) levels in one bedrock well that was slightly above background bedrock radium levels. Radium is a naturally-occurring radioactive metal and while included in the groundwater monitoring program, it is not included in the final suite of isotopes for the License Termination Plan.

The following activities were conducted during this period:

• Cut the reactor vessel into three (3) sections: Conical Section, Cylindrical Section, and Lower Reactor Vessel (LRV).

• The Conical and Cylindrical Sections were segmented into smaller pieces to facilitate packaging. These segmented pieces were packaged and shipped off site.

• Removed the bases and stands from the three (3) Primary Sodium Pumps and three (3) Intermediate Heat Exchangers.

• Removed additional graphite shielding from on and around reactor to facilitate cutting the reactor into sections. Some graphite remains and will be removed only as needed for access to allow for the shielding effect as long as possible.

• Began cutting the Transition Deck free of the LRV at the end of the period.

Enclosure to NRC-11-0043 Page 4

• Removed fuel pool sump pumps 6 and 7 and associated piping.

• Pumped out water from Maintenance Pit Sump, cleaned pit and removed decontamination chamber.

• Removed slightly contaminated silt from the bottoms of Sumps 10, 4, and 1.

• Evaporated plant water using drum dryers.

• Removed abandoned equipment in Reactor Building lower level.

• Cleaned out Fuel and Repair Building (FARB) Dump Tank Room.

• Began neutralizing caustic and removing liquid and sludge in primary sodium 30" lines at the end of the period.

• Removed abandoned hot sump equipment.

• Removed Steam Cleaning Chamber equipment and sealed floor penetrations.

• Removed abandoned pipe and cables in the NaK Room.

• Removed equipment from the Cold Trap Room.

• Removed abandoned pipe and cables from the New Fuel Loading Tunnel.

• Began removal of abandoned pipes and cables in the FARB.

• Removed bottom portion of Sodium Tunnel liner.

• Removed steel shot from FARB Pump Room.

• Decontaminated Dump Tank Room, East Sodium Gallery, Decay Pool, and Waste Tank Room.

• Prepared for Final Status Surveys (FSS).

Some of the removed components have already been shipped offsite. As discussed in Reference 2, the majority of accumulated low level radioactive waste will be shipped offsite for disposal prior to the return to passive monitoring SAFSTOR status.

Radiological Surveys Radiological surveys were conducted in accordance with plant procedures. Unexpected radiological conditions were encountered only in one area during this reporting period.

Sodium Tunnel survey found contamination in concrete joints underneath the steel liner.

The bottom portion of the liner was removed for further survey, and fixed contamination was found in the concrete structure. Remediation is being performed.

3.1 Radiological Shipments The Fermi 1 team shipped the following materials offsite without incident from Fermi 1 during the reporting period. Tools and equipment shipped to Fermi 2 are not included in this table.

All measurable releases were associated with the decommissioning project. The maximum dose to an offsite member of the public from these releases was 1.0 E-6 mrem Total Effective Dose Equivalent (TEDE) derived from a total of 2.1 mCi of tritium. The gaseous effluent releases were below the Technical Specification air dose limit of 10 mrad of gamma radiation and 20 mrad of beta radiation per year. The individual dose calculated due to gaseous effluent releases was below the Technical Specification dose limit of 5 mrem Total Effective Dose Equivalent.

5.0 50.59 EVALUATIONS, DESIGN CHANGES AND LER's 5.1 10 CFR 50.59 The Fermi 1 team conducted one 10 CFR 50.59 evaluation during this period. Screenings determined that 50.59 evaluations were not required for other activities.

10-008-SE 50.59 Evaluation addresses abandoning the Fuel and Repair Building (FARB) radioactive drain lines and hot sump.

Enclosure to NRC-11-0043 Page 8 Note that the drain lines and hot sump will not be abandoned at this time due to the return of the facility to the monitored passive SAFSTOR status. Detroit Edison will address the drain lines and hot sump during the planning for return to active decommissioning.

Summary:

This 50.59 evaluation supports design change 09-025-DC, Fermi 1 Safety Analysis Report change 09-023-SAR and work request EF1-09-024 for abandoning the radioactive drain lines and hot sump in the FARB as part of decommissioning.

The 50.59 evaluation addressed that the FARB systems containing radioactive water during plant operation have been abandoned and drained. The waste tanks and majority of the fuel pool liners had been removed at the time the evaluation was written. The steam cleaning chamber equipment removal was in progress. Therefore, the main reason a radioactive water drain system was designed and installed for the FARB no longer applies. The evaluation addressed that the work request would have a hold point to ensure that the temporary evaporation of contaminated water in the FARB was completed prior to plugging the drains and removing the sump. Remaining water sources in the FARB would be due to rain, snow or groundwater in leakage.

The 50.59 evaluation concluded that there would not be more than a minimal increase in the frequency or consequences of an accident or malfunction after this change would be implemented. The change would not create a possibility of an accident of a different type or malfunction of a system, structure or component important to safety with a different result. Since no fuel is stored at Fermi 1, there are no fission product barriers with design limits. Based on the evaluation, NRC prior review was not required.

5.2 Design Changes During this reporting period, Design Change 08-045-DC was completed with the removals of the Liquid Waste and Gaseous Waste systems, abandoned hot sump equipment, and control panel in the FARB. No other Design Changes were implemented during this reporting period.

5.3 Licensee Event Reports There were no Licensee Event Reports during this reporting period.

6.0 AUDIT SUBCOMMITTEE The Audit Subcommittee inspected the physical facility and reviewed the Technical Specification surveillance records during the reporting period. No significant problems were identified.

All audit reports are maintained on file.
