The inspection scope and findings were summarized on May 29, 1987, with those persons indicated in paragraph 1 above. The inspector described the areas inspected and discussed in detail the inspection finding No dissenting comments were received from the license The licensee did not identify as proprietary any of the materials provided j to or reviewed by the inspector during this inspection ] Licensee Action on Previous Enforcement Matters (Closed) Unresolved Item (259, 260 and 296/81-01-09) Corrective Action to be Taken on Triennial Fire Protection Audit. TVA has made a detail review of the fire protection features at Browns Ferry and compared these features with the NRC guidelines of NUREG 080 Items or features which do not meet these guidelines are to be modified to conform to the guidelines or appropriate justifications are to be submitted for NRC revie This evaluation is being tracked by TVA item NC0 86-0326-104 and the specific Region II audit items of concern are being tracked by TVA item SLT 86-1032-00 The commitment for TVA to evaluate / review Browns Ferry for compliance to the NRC guidelines of NUREG 0800 and provide a modification schedule prior to startup is included in Nuclear Performance Plan Volume This unresolved item was not based on regulatory requirement. This item is close ,

b. (Closed) Unresolved Item (259, 260 and 296/82-15-07) Fire Protection Technical Specifications. The Technical Specifications have been revised to indicate that the applicability of the fire protection systems applies only to the applicable fire suppression and/or-detection systems installed for the reactor building, diesel building, control bay, intake pumping station, and cable trays along the south wall of the turbine building at 586' elevation. The cable

-

tunnel has a fire detection system but does not have a fire suppression syste This was reviewed and approved by the NRC following the 1975 fir Therefore, it appears that a fixed suppression system is not required for this area. TVA has proposed to remove all fire protection features from the Technical Specifica-tions as permitted by Generic Letter 86-10. This item is close c. (Closed) Unresolved Item (259, 260 and 296/82-15-08), Fire Protection Piping 1.eak All deteriorated and leaking fire protection piping within che plant is to replaced prior to startu The main feed piping to the AFF foam systems for the motor generator sets have experienced a number of leaks and is to be replaced. Repairs are to be made using higher quality ASTM A106 Grade B piping in lieu of the original specified ASTM A53 grade piping. Appropriate corrective actions have been taken and as future leaks occur appropriate repairs will be made. This item is being tracked by TVA item No. SLT-86-1033-001 and is therefore close d. (Closed) Unresolved Item (259, 260 and 296/84-17-04), Unsupervised Sprinkler System and Fire Pump Actuation, Circuits.- This item has been evaluated by TVA as part of the detail Browns Ferry fire protection evaluatio Refer to above unresolved item 259, 260 and 296/81-01-09. TVA's final report will either provide a schedule date that these items will be corrected or provide sufficient justification as to why modifications are not required. The Report will be reviewed by the NRC staff. Therefore, this item is close e. (Closed) Unresolved Item (259, 260 and 296/84-17-05), Unsupervised C0 System Actuation Circuit To offset this-discrepancy TVA has initiated a monthly surveillance using procedure SI-4.11.C.1&5, system operability Testing for the COof2Smoke systemsand Heat in the Detectors, diesel to verify generator buil CO, ding This meets the intent of the NRC requirements. Therefore, this item is close f. (Closed) Unresolved Item (259, 260 and 296/84-17-09), Inadequate Onsite foam Capabilities. TVA has made an agreement with the nearby offsite Clement Fire Department who has a mutual aid agreement with a nember of area fire departments. These departments have sufficient manpower and equipment, including foam, to combat a major fir This resolves the inspector's concerns and closes this ite .

Annual Fire Protection / Prevention Audit Team with Qualified Fire

Protection Personne TVA's letter of June 20, 1986 to the NRC ,

Region II states that fire protection engineering personnel from 1 other internal TVA organizations are to be used to conduct future fire protection audits. The most recent April 1987 audit utilized a fire protection engineer from TVA's Division of Property and i Services. This appears to meet the intent of NRC Generic Letter j 82-21 and closes this ite l (Closed) Violation (259, 260 and 296/86-09-03), Failure to Include Piping Fire Barrier Penetrations Into a Surveillance Program. TVA has inspected all mechanical fire barrier penetrations and all identified installation discrepancies have been included in a repair program. Approximately 80% of the identified discrepancies have been corrected as required by a contracto The remaining discrepancies are to be repaired by on-site TVA personne The contractor is developing a surveillance inspection procedure which will identify all penetrations, type of construction, configuration, etc. for use during future surveillance to verify that all fire barrier penetrations are functional. This work which is being tracked by TVA NC0 86-0232-003 and 004 is scheduled to be completed by July 16,
