Tennessee Valley Authority (TVA) officials said Friday they are requesting proposals from five major engineering firms for design and engineering work on the repair of the Unit 1 reactor. At the same time, TVA Chief Financial Officer David Smith said he is contacting major Wall Street firms and other financiers about their interest in joint ventures, leases or other financing options for the $1.8 billion repair project.
TVA expects to employ more than 500 contract engineers to prepare plans for the upgrade of the oldest reactor at Browns Ferry, which was idled in 1985. TVA is using a similar approach to repair the Unit 1 reactor at Browns Ferry that it did to upgrade the other two units at the plant.
The Unit 1 reactor, still has its operating license from the NRC.

TVA (Tennessee Valley Authority's) got the go-ahead from NRC early November 19. Operators started withdrawing control rods from the longidled unit that morning and it reached a self -sustained chain reaction around noon.
Browns Ferry-3 has been shut since March 1985, when management turmoil forced TVA to close all three units there. Browns Ferry-3 was restarted in 1991 following an overhaul of its physical condition and management. Browns Ferry-1 is on indefinite standby, and TVA has no immediate plans to restart it.
The cost of returning Browns Ferry-3 to service is forecast by TVA to total $1,4-billion. Contractors together with TVA employees, have devoted 6,7-million engineering hours and 11,5-million construction hours to the job.
Workers installed more than 7.000 pipe hangers, 15.000 conduit supports, 30 miles of conduit, and 138 miles of cable, according to TVA. Specialists also reviewed and updated more than 1.100 procedures and overhauled approximately 75 plant systems.
