US Nuclear; Failing Casks, Cracked Concrete And Foot Dragging On Safety
[Translate] 30 of the US’s 100+ nuclear plants have ordered spent fuel pool water level monitoring systems. The issue of this kind of equipment came up again during hurricane Sandy as both members of the public and experts questioned if the nuclear plants impacted by the storm had upgraded spent fuel pool equipment. The new equipment to monitor and provide water to the pool was suggested by the post Fukushima committee that looked at what failed and could fail at US reactors. It is not clear if the remaining units in the US have not ordered such equipment or have already ordered such equipment. The water level monitoring system is only part of the suggested upgrades and comes with a 7 day battery pack. Dry Casks Failing In The US The NRC found multiple … Read entire article »

TEPCO’s New Decontamination System Delayed By Tank Failures
[Translate] TEPCO has announced a delay in the start up of the new decontamination system at Fukushima Daiichi. The system was supposed to go online this fall but remains delayed as TEPCO tries to find acceptable storage containers for the sludge created by the new system. TEPCO did drop tests recently to see how these new containers would hold up to various ways they might be dropped as they are moved about the plant. The drop tests were quite the series of failures. The tanks were procured from Energy Solutions of Barnwell, SC (US), a company located near the Savannah River nuclear site. The High Integrity Container tested by TEPCO doesn’t mention the exact material composition. A press release from Energy Solutions announcing their partnership with Toshiba to provide these casks … Read entire article »
