In March 1991, the NRC’s Operations Center was located in the Maryland National Bank Building, in Bethesda, Md., even though the first building of the new, soon-to-be consolidated NRC headquarters complex was occupied in Rockville, Md.
In this photo, then-director of the Division of Safety Systems Analysis, Brian Sheron, briefs the Executive Team during an exercise with the St. Lucie nuclear power plant, in Florida.
At the head of the table (lower left) is Commissioner Ken Rogers, who is joined by a number of high-ranking NRC officials from various offices.
Fast forward to today.
Now, the NRC’s Operations Center is a modern facility using the latest technologies. During this emergency preparedness exercise with the Fermi nuclear power plant, held in April 2014, the Executive Team gets briefings over webcam, while monitoring information on laptops and keeping an eye on the content of simulated social media.
In this exercise, the Executive Team was headed by then-Commissioner George Apostolakis, center, seated.

The Japanese government and TEPCO would be the holders of any video footage that might exist from the accident site. The NRC’s records from that time are the Operations Center transcripts and e-mails released through FOIA requests.

I wonder if the NRC would release its webcam data from the 3/11/11 Fukushima triple meltdown?
I have seen some of the emails released* and believe that the webcam data would offer yet another perspective of how the NRC reacts to a real nuclear emergency.
* Here is a great listing of internal NRC emails that give a sense of what was being discussed immediately after 3/11/11 occurred: http://pbadupws.nrc.gov/docs/ML1117/ML11175A278.pdf
