Even the tiniest mistake during an operation to extract over 1,300 fuel rods at the crippled Fukushima nuclear power plant in Japan could lead to a series of cascading failures with an apocalyptic outcome, fallout researcher Christina Consolo told RT.
Fukushima operator TEPCO wants to extract 400 tons worth of spent fuel rods stored in a pool at the plant’s damaged Reactor No. 4. The removal would have to be done manually from the top store of the damaged building in the radiation-contaminated environment.
In the worst-case scenario, a mishandled rod may go critical, resulting in an above-ground meltdown releasing radioactive fallout with no way to stop it, said Consolo, who is the founder and host of Nuked Radio. But leaving the things as they are is not an option, because statistical risk of a similarly bad outcome increases every day, she said.
RT: How serious is the fuel rod situation compared to the danger of contaminated water build-up which we already know about?
Christina Consolo: Although fuel rod removal happens on a daily basis at the 430+ nuclear sites around the world, it is a very delicate procedure even under the best of circumstances. What makes fuel removal at Fukushima so dangerous and complex is that it will be attempted on a fuel pool whose integrity has been severely compromised. However, it must be attempted as Reactor 4 has the most significant problems structurally, and this pool is on the top floor of the building.
There are numerous other reasons that this will be a dangerous undertaking.
- The racks inside the pool that contain this fuel were damaged by the explosion in the early days of the accident.
- Zirconium cladding which encased the rods burned when water levels dropped, but to what extent the rods have been damaged is not known, and probably won’t be until removal is attempted.
- Saltwater cooling has caused corrosion of the pool walls, and probably the fuel rods and racks.
- The building is sinking.
- The cranes that normally lift the fuel were destroyed.
- Computer-guided removal will not be possible; everything will have to be done manually.
- TEPCO cannot attempt this process without humans, which will manage this enormous task while being bombarded – with radiation during the extraction and casking.
- The process of removing each rod will have to be repeated over 1,500 times without incident.
- Moving damaged nuclear fuel under such complex conditions could result in a criticality if the rods come into close proximity to one another, which would then set off a chain reaction that cannot be stopped.
‘One of the worst, but most important jobs anyone has ever had to do’
My second biggest concern would be the physical and mental fitness of the workers that will be in such close proximity to exposed fuel during this extraction process. They will be the ones guiding this operation, and will need to be in the highest state of alertness to have any chance at all of executing this plan manually and successfully. Many of their senses, most importantly eyesight, will be hindered by the apparatus that will need to be worn during their exposure, to prevent immediate death from lifting compromised fuel rods out of the pool and placing them in casks, or in the common spent fuel pool located a short distance away.
Think for a moment what that might be like through the eyes of one of these workers; it will be hot, uncomfortable, your senses shielded, and you would be filled with anxiety. You are standing on a building that is close to collapse. Even with the strongest protection possible, workers will have to be removed and replaced often. So you don’t have the benefit of doing such a critical task and knowing and trusting your comrades, as they will frequently have to be replaced when their radiation dose limits are reached. If they exhibit physical or mental signs of radiation exposure, they will have be replaced more often.
‘The mainstream media, world governments, nuclear agencies, health organizations, weather reporters, and the health care industry has completely ignored three ongoing triple meltdowns that have never been contained’
An obvious attempt to downplay this disaster and its consequences have been repeated over and over again from ‘experts’ in the nuclear industry that also have a vested interest in their industry remaining intact. And, there has been a lot of misleading information released by TEPCO, which an hour or two of reading by a diligent reporter would have uncovered, in particular the definition of ‘cold shutdown.’
