ENCLOSURE 1 NOTICE OF DEVIATION Tennessee Valley Authority Docket,Nos. 50-259, 50-260, and 50-296 Browns Ferry 1, 2, and 3 License Nos. DPR-33, DPR-52 and DPR-68 The following deviations were identified during a Nuclear Regulatory Commission (NRC) inspection conducted on January 1-31, 1987:
A.
Final Safety Analysis Report Section 10.11, Fire Protection Systems states that each -unit battery room and battery board rooms contain drains and curbs.
These are provided to remove a minimum of 100% flow, assuming all sprinkler heads in one room are open and 200 gpm is being provided by hand hoses.
The drains and curbs were also to be installed for preventing personnel hazard and damage to safety equipment due to battery acid spillage.
Contrary to tha above, this requirement was not met in that none of the rooms have curbs installed.
Units 1 and 3 battery board rooms do not contain drains.
The engineering change notice (L-1978) that installed the drains and curbs was completed in 1978.
On December 25, 1986, expandable plugs were placed in all of the rooms which do contain drains pending resolution of a possible Secondary Containment breach due to a common drain header with the reactor building floor drains.
This deviation is applicable to all three units.
B.
The Browns Ferry Nuclear Plant Final Safety Analysis Report Section 10.2.4, New Fuel Storage, requires that each new fuel storage vault be provided with neutron dosimeters.
Contrary to the above, no neutron dosimeters were provided on any of the Unit 1, 2 or 3 new fuel storage vaults.
An inspection conducted on January 27, 1987, by licensee representatives and the inspector failed to locate any neutron dosimeters.
It is not known how long this condition may have existed.
This deviation is applicable to all three units.
