The U.K. Nuclear Decommissioning Authority (NDA) on Wednesday released a quarterly performance report for NDA sites managed by Sellafield Ltd., Magnox Ltd., Dounreay Site Restoration Ltd., and Low Level Waste Repository Ltd.
The quarterly progress report covers performance targets from April to June 2016 for site decommissioning and remediation; spent fuels; nuclear materials; integrated waste management; and critical enablers at the various facilities.
Sellafield Ltd., which manages sites at Sellafield in West Cumbria on behalf of the NDA, has completed or is on schedule for 20 targets. Three targets are behind schedule with the possibility of recovery, including the first export of sludge to the Waste Encapsulation Plant.
Magnox Ltd., which manages 12 nuclear sites on behalf of NDA, is on schedule for 44 targets and behind schedule with the possibility of recovery for 12 others. Among those behind schedule are: defueling at Wylfa; shielded area waste retrieval at Berkeley; two tasks at Bradwell; and items at Harwell and Chapelcross.
Dounreay Site Restoration Ltd., which manages Britain’s former fast reactor research and development center, is on schedule for four targets, but has deferred six other items. The progress on the delayed items involved “exotic fuels” that have historically been held at Dounreay. The report says the strategy has been modified to focus on transfer and consolidation of exotic fuels from Dounreay to Sellafield.
Low Level Waste Repository Ltd., which manages the nation’s low-level waste program, is on schedule for 12 targets and behind on one. Completion of upgrades to the site’s perimeter fencing has been delayed because of challenges to ground conditions.
