Tokyo Electric workers are to begin work at the Fukushima Daiichi nuclear power plant to create underground frozen walls at the Unit 2 and Unit 3 turbine buildings on Wednesday. The utility is also digging wells across the compound to determine whether or not water is leaking directly from the reactor buildings.

Enormous amounts of coolant water is injected around the clock to prevent the melted nuclear fuel from overheating is leaking from the damaged reactor containment vessels and mixing with groundwater in the reactor buildings, turbine buildings, and various underground tunnels, before seeping into the ground and reaching the sea.

The utility hopes that the ice walls will prevent highly radioactive wastewater from flowing into the ocean.

Workers will dig vertical holes which will house pipes to inject liquid coolant to create frozen walls to block the water. They will have to contend with cables and other obstructions in the tunnels which may hinder the work.

Workers are unable to access the underground tunnels due to the high radiation levels and the contaminated water, and will be forced to perform their work using remote-controlled cameras.

According to the schedule provided by TEPCO, workers are scheduled to finish installing the pipes by mid to late March.

Many outside experts have expressed skepticism as to whether or not the project will offer any real benefit, arguing that the technique has only ever been used on a small scale. There is even concern that the ice wall will drive the contaminated water even deeper underground.

  1. There is no way to really clean up radionuclides once they are created.

    All they can do is move the radionuclides around…they cannot be destroyed.

    Meanwhile, look at this map showing where the idiots are selling new nuclear energy to idiots who are buying it:


  2. My understanding of the government’s* ice wall plan is that the intention is to keep groundwater out of the reactor and turbine buildings. The reason that the amount of stored water keeps increasing is that groundwater is coming into the cycle, seeping in through building/trench walls. All water now injected into the reactors was previously pumped out of the turbine buildings and treated – if that was all there was, the amounts of stored water would have just about stopped growing a couple of years ago.

    * The Japanese government is set on this ice-wall plan. I don’t know how Tepco, who merely have to carry it out, feel about it.

  3. I stated a similar note on another topic however like to make sure it’s heard. If the ice wall is not working as intended and groundwater is a result of flow downhill. Would a trench at sea level extending around the back or the plant to the ocean effectively stop the downhill groundwater flow? It might be just enough to stop the flow at the plant into the sea daily. It would be cheap. And the less water to be contaminated by passing under the plant the better. This “I think” is a good idea, and is at least a suggestion to help the situation. Thoughts?
