Work on the 1,100 MW Watts Bar nuclear power plant Unit 2 has shifted to completion and testing of individual plant systems, plant operator Tennessee Valley Authority (TVA) said.
TVA released its quarterly update on the progress of the reactor, covering a period from August-October 2013. TVA said the project remains on schedule and on budget. Completion of Watts Bar 2 is projected between September 2015 and June 2016, with a most likely completion date of December 2015. The revised estimate to complete Watts Bar 2 included additional funding of $1.5 billion to $2 billion, with the total cost expected to be between $4 billion and $4.5 billion.
The timetable provides for a logical sequence for completing and testing the systems. The open vessel testing, which involves pumping water through systems that are used when shutting down the reactor, will begin in the spring.
Some of the challenges workers face include testing shared systems without impacting Unit 1’s operation, completing complex work and required documentation, addressing regulatory and licensing issues, and successfully transitioning the site to dual-unit operation.
