Tepco withholds “black box” data about Fukushima nuclear disaster via SimplyInfo

In April of 2010 TEPCO signed a contract with high tech security company Magna BSP to provide a sophisticated video and trespass detection system at the Fukushima Daiichi nuclear plant. This was the first installation of what was to be a series of similar installations at nuclear plants around Japan, coordinated between the government and nuclear operators. The system was installed at Fukushima Daiichi in 2010

Two TEPCO workers who were trained on the system weeks before the disaster were confirmed to have been among the Fukushima 50 who stayed at the plant during the worst of the disaster. To date TEPCO has not acknowledged the existence of the system or volunteered any of the video and data captured by the system to the public or the press. This data was never taken into account by any of the investigations into the disaster that commenced in 2011 and 2012.

This system holds critical data that could shed light on many of the early events at the plant. It should be made public in an unedited and usable format asap.
Low tech security systems record a minimum of a 24 hour loop. The high tech system installed at Fukushima Daiichi would likely have a much longer data storage routine set up. This system would have been recording and saving data, possibly for a long time or in a permanent manner that saved all historical data.

The nature of modern high tech security systems leaves little room for TEPCO to deny the existence of this early data. The CEO of Magna BSP made this statement to the press in 2011

“Although there is no access to the area, Siboni said the cameras from his company’s security system – which were installed high up – were probably not damaged and likely captured the post-earthquake explosions at the site, as well as the impact of the tsunami.”

The company also told the press that the perimeter security system could have recorded radiation via the IR portion of those cameras and could give important data about radiation levels at the plant.
