This refers to the inspection, conducted by Messrs.D.G.Hinckley, A.D.Kowalczuk and R.F.Sullivan of this office on June 16-25 and July 1-5, 1976, of activities authorized by NRC Operating License Nos.DPR-33 and DPR-.52 for'the Browns Ferry Units 1 and 2 facilities, and to the discussion of our'findings held with Messrs.Green, Dewease, and Denton at the conclusion of the inspection.
The inspection was an examination of the activities conducted'nder your" license hsIthey relate'o radiation safety and to compliance with the Commission's rules and regulations and the conditions of your license.The inspection consisted of selective examination of procedures and representative records, interviews with personnel, and observations by the inspector.
During the inspection, it was found that certain activities under your license appear to be in noncompliance with NRC requirements.
These items and references to pertinent requirements are listed in Section I of the summary of the enclosed report.Corrective.
actions to:prevent recurrence were completed prior to the conclusion of this inspection; therefore, a reply to these items of noncompliance is not requested.
In accordance with Section 2.790 of the NRC's"Rules of Practice," Part 2, Title 10, Code of Federal Regulations, a copy of thi's letter and the enclosed inspection report will be placed in the NRC's Public Docu-ment Room.If this report contains any information that you believe to be proprietary, it is necessary that you submit a written application to this office requesting that such information be withheld from public disclosure.
If no proprietary information is identified, a written statement to that effect should be submitted.
If an application is

b.Phase II Surveillance Testin The purpose.of this phase was to reestablish the plant surveil>>lance program for Unit 1.The program was based on.the proposed Technical'pecifications for the restart of Units 1 and 2 which was consistent with.the program described in the'Recovery Plan.'here was a total of 217 tests listed on this program.All but 12 were successfully completed by, July 2, 1976.The 12 were considered not necessary for fuel loading and were scheduled for completion prior to startup.PORC made a final review of Phase II on July 2, 1976, and concurred in the exception list.'The inspector rev'iewed the status of the test program and con-firmed the completion of all except the 12 tests previously mentioned.
The inspector confirmed that the systems involved in these 12 tests would'ot.affect fuel loading.The test data package for 48 individual tests were selected at random for detailed review by the.inspector.
Results indicated that criteria were.met and that.any listed exceptions were satisfied.
C~Phase III Master.Checklist The master checklist had been completed up to the step where the Plant Superintendent authorized fuel loading which was being held up until he received NRC authorization to load fuel.*Exception items were listed with the basis given:for not needing completion for fuel loading.The inspector con-curred that all exception items dealt with systems or components not required fouel, loading.Based on the inspectors observations relating to the retest program and the prefuel loading functional"test program, they telephoned the IE:II office on July 2',:to forward their findings which supported plant readiness to load fuel only in Unit l." 4.Unit 1 Fuel Loadin The.license for Unit 1 was amended July 2, 1976, to authorize fuel reloading only with control rods disabled in the full in position as was the case for Unit ~i IE Rpt.Nos.50-259/76-15.and 50-260/76-15 III-3 Inspectors witnessed fuel loading activities on July 4 and 5 which included inserting the first bundle at 3:18 p.m.on July 4.Selected operations were observed in the control room and refueling floor on both day and night shifts.The inspectors noted that activities were in conformance with written procedure SRI 3'hich covered the special loading operations required by'he license amendment.
The prerequisites for fuel loading were satisfied and the inspectors verified proper valve lineup for the control rod drive hydraulic units and the removal of fuses to disable the normal drive controls.5.Plant 0 erations.A review was made of recent, plant activities and operations during the period when the fire recovery program was nearing completion and when plans for restart were underway.The review was to determine conformance with the Interim Technical Specifications and commitments in the'Recovery Plan'n the areas selected.The review included examination of the followng, records for the periods indicated:
