' PREFACE.

This' annual report is' issued by the Detroit Edison Company in compliance with the provisions of the United Stated Nuclear Regulatory Commission, {'

Provisional Operating License No. DPR-9, as amended and:is intended to' provide a summary of the activities carried out and the results of the l facility surveillance program at the the decommissioned Enrico Fermi Atomic Power Plant, Unit 1, during the twelve (12) months ending June 30,'1989 i

II SAFSTOR STATUS Primary System The primary system, as established during decontamination, remains blanketed with carbon dioxide. This was done to provide a passivating atmosphere for any sodium remains. A continuous supply of carbon dioxide maintains this cover gas at approximately 2 inches of water column pressure.

Sodium Storage Tanks A one to five psig nitrogen cover gas is maintained on the three drained primary sodium storage tanks.

. Fermi 1 License Extension The NRC issued Amendment No. 9 to the Possession-Only License No. DRP-9 for Fermi Unit 1 on April 28, 1989. This amendment renews the possessioneonly license until March 20, 2025 and revises the Technical Specifications.

III HEALTH PHYSICS Personnel Exposure From June 30, 1988 through June 30, 1989, all personnel monitored in Fermi 1 wore their Fermi 2 TLDs and DRDs. There were no exposures attributable to Fermi 1 recorded.

Environmental Surveys

'During the' period of July 1988 to' June 1989, approximately twenty environmental monitoring samples were obtained for the Fermi 1 Environmental Radiological Monitoring Program. These samples consisted of l, s>Arlace and-city potable waters, along with lake.and creek sediments. The

..0ater samples indicate no significant activity. The sediment samples indicated small amounts of Cs-137 The Cs-137 levels are consistent with

, those levels' detected in previous years.

l

l. The sediment sample taken on 9/8/88 in the South Lagoon for Fermi.1 L  : indicates no Cs-137 present. : This low value for Cs-137 is due to a l- statistical sampling anomaly. Cs-137 is typically found in soil and lake l

sediments and is residual activity from atomic weapons testing.

1. Water Intrusion Alarm - Continuity tests of the water intrusion alarm circuits for FARB, Lower Reactor Building and Biological shie.1d wall areas were conducted as requred by Technical Specifications. No discrepancies were encountered during this reporting period.

2. Cover Gas Pressure - Weekly checks on cover gas pressure on primary system and primary sodium storage tanks were performed. No discrepancies were encountered during.this reporting period.

Monthly Inspections

' 't . Contro11ed' Area Inspections - Visual inspection of fences, the gates, doors (locked) operation of waste sump pumps and liquid levels of MK 7, 8, 9 and 15 were conducted within specified intervals. No discrepancies were.found during this report per'od.

Quarterly Tests

1. Smear Surveys'- The Reactor Building and FARB were checked for presence of gamma radiation and loose contamination. The results of these smear surveys-indicated no decontamination procedures were required.

VI NOTEWORTHY ITEMS

1. "The Administrative Controls and Surveillance Procedures Manual, Revision 0, was written in accordance with the newly-amended license.

This Manual was approved by the Review Committee on August 23, 1989.

s 2. Tanks MK-9 and MK-15 were pumped down to the minimum levels that.would still allow tank level indication. The liquid was processed by a radwaste vendor for use at Fermi 2. The procedures and practices used ,

during this process were carefully reviewed'by the Fermi 1 Review  !

Committee. A Safety Evaluation of this activity was performed in accordance with 10 CFR 50.59. The final Safety Evaluation was approved-by the Fermi 1l Review Committee.

3 Barbed wire was added to the top of the RCA' fence to ensure compliance with the fence height requirements in the revised Technical Specifications.

.4. The review of permanent plant records for final disposition was started during this review period and is on-going.
