Layoff warnings continue to go out to Shaw AREVA MOX Services employees.

The proposed federal budget does not include adequate funding for the mixed-oxide fuel fabrication facility, which is triggering more layoff talks and the distribution of Worker Adjustment and Retraining Notification Act notices. The notices first started in early June.

The budget request to Congress from President Barack Obama's administration seeks $503 million for programs with most of it earmarked for the MOX plant, but that's approximately $200 million less than what was provided in last year's continuing resolution. Because of this, Shaw AREVA MOX Services is spending less money.

The plant is about 60 percent complete, but the project has undergone years of cost overruns and delays. The Government Accountability Office reports the plant is $3 billion over budget, now costing an estimated $7.7 billion.

The Worker Adjustment and Retraining Notification Act requires most employers with 100 or more employees to provide notification 60 calendar days in advance of plant closings and mass layoffs, according to the U.S. Department of Labor.
