50-296 BROWNS FERRY NUCLEAR PLANT (BfN) - INFORMATION ON SPECIAL NUCLEAR MATERIAL (SNM) ACCOUNTABILITY On November 8, 1989, TVA determined that eight incore detectors in the Radwaste Evaporator Building were not accounted for in the SNM inventory.
TVA considers this discovery to be significant and has taken immediate corrective L
action.
This letter serves to document the actions that have and will be taken. TVA will inform the NRC of progress and will report the results of all investigative work and associated corrective actions.
When the eight detectors were discovered, the condition was reviewed for i
reportability.
The incident was deemed not reportable since SNM ltems had been "found," and not " lost." Loss of this SNM had been initially reported in 1986. It was decided at that time that the event would be reported via a Special Report to NRC; however, in light of the significan% of this issue, TVA has now concluded that this situation should have been isnmediately reported.
Plant management now requires any issue where repoetability is in question to be immediately brought to the Plant knager's or Duty Manager's attention.
TVA believes that implementing the plan in the enclosure will establish an accurate, maintainable SNM baseline inventory.
The Quality Assurance organization will perform an independent review of the program and the inventory to provide an additional level of confidence. During this process, if any additional inventory discrepancies are found, they will be reported.
TVA will review our existing SNH inventory control program as well as the implementation of previous commitments to NRC relative to this program.
Any identified weaknesses will be corrected.
Specifically, the findings from investigations against previous commitments in response to NRC Inspection Reports 86-38 and 87-29 will be reviewed to determine why the previous corrective actions failed to solve the problem.

.E Enclosure InYentory Browns Ferry Nuclear Plant (BFN) will perform physical inventories of all SNM material by implementing a developed search plan. The Quality Assurance f
organization will perform our independent review of the program and the inventory to provide an additional level of confidence. To date, the following areas have been searched for any additional SNM not previously documented in our initial baseline inventory all traversing incore probe roomst all drywell rod galleries and sump pump roomst Radwaste Evaporator Buildingt Power Stores Warehouse SNM Storage Areat chemistry lab vault; Radeon instrument laboratory SNM storage cabinett LPRM box on the Refuel Floor. The discrepancies noted to date were documented by one-hour notifications to NRC bacween November 25 and November 28, 1980 Fuel and
(
Non-fuel SNM sorted in ;he Spent Fuel Storage Pools (SFSP) will be inventoried. Where necessary SNM has been segregated to ensure continued accountability. Currently, TVA is developing a method for baseline inventory of installed incore detectors to verify their serial numbers.
During this activity, some record discrepancies may be noted similar to those noted in our Special Report 88-01 dated October 7, 1989.
Finally, the video-tape documenting the Unit 2 core configuration will be reviewed to ensure current inventory is properly identified.
Disposal TVA plans to dispose of spent SNM items no longer required for the operation of BFN. During the disposal, staging areas will be designated to temporarily store SNM for shipment assuring positive SNM control.
Itaining TVA will develop ard implement a detailed training program for the identification of Source Range and Intermediate Range Monitors.
TVA will assess the experience and training of BFN personnel involved in SNM control.

l TVA will review all previous SNM commitments made to NRC for adequate implementation. Additionally, TVA will review assumptions of previous corrective actions and control programs and apply any lessons learned to other areas (e.g., by-product materials).

NRC_.Repor.t TVA will submit a final Licensee Event Report to address the November 8, 1989 j
event and subsequent SNM findings.
