On Jan 19, 2012 TEPCO, the operator of the crippled Fukushima Daiichi Nuclear Power Plant, made the first visual inspection inside the primary containment vessel of reactor number 2 using and industrial endoscope.

  • I'm wondering whether the endoscope is fibre optic, if so the camera is remote from the lens and the radiation 'noise' would be minimised.

  • @tifrap the camera in mounted on the tip of the instruments. Look at the specification of the borescope

  • @tifrap the camera in mounted on the tip of the instruments. This is what is written on the spec of the borescope

  • @joazde maybe you could freeze a one second frame count all the "noise" spots and figure out desintegrations/sec. but thats a stretch....

  • @tom432011 the camera can withstand 1000 Gy that is very similar to 1000 Sv. Be careful not to mess up dose and dose rate. And btw the camera is not broken.

  • @joazde The camera can withstand 1000Sv/h. But they still broke it.

  • @joazde don't think it's easy, the used instruments are different.

    10Sv/h is a big number and that's the reason why they need to flood everything with water before opening and start the fuel removal.

    But to flood, they first need to find and fix the leaks. Not an easy task.

  • I wonder if one could find out radiation estimations measuring from the "hotspots" on the cameras sensor. Some parts, for example from 11:04 on look like much more than the 10Sv/h image from this video watch?v=MsG6JsMAJ_Q , which is awfully lot already.

  • Oh yeah everything's fine. Nothing to see here, no damage just look at them pipes. Just a little radioactive rain thats all.
