Plan to End Fukushima Nuclear Crisis Leaves Reactor Leaking Radiation For Another 3 Months

Japan’s plan to end the Fukushima nuclear reactor crisis involves letting radiation leak for the next 3 months.

The manufacturer of the Fukushima nuclear reactor revealed the plan to end the nuclear reactor radiation leak which will be split into 3 phases over 10 years. The first stage will take about three months during which they plan to stabilize the nuclear reactor and spent fuel pools while preventing the radiation leak from increasing.


The first article from NHK reveals the 3 phase plan in which the first phase will focus on stopping the radiation leak from increasing.

Reactor makers draft 10-year decommission plan

Japanese manufacturer Toshiba, which helped build the Fukushima Daiichi plant’s now crippled nuclear reactors, says decommissioning them will take at least 10 years.

Toshiba has drafted a plan with 4 US companies in the nuclear power industry to decommission the plant, including the Number 2 and 3 reactors that it built.

The company’s President Norio Sasaki said on Thursday that it has submitted the proposal to Tokyo Electric Power and the Industry Ministry. Prime Minister Naoto Kan had earlier asked the utility to come up with a plan to end the nuclear crisis.

The proposal is divided into 3 phases. The short-term plan, likely to take several months, involves cooling and stabilizing reactors and spent fuel pools, while preventing radioactive water from increasing.
Toshiba will then move toward the medium-term plan, involving the safe removal of nuclear fuel rods from the pools and pressure vessels, using special cranes to be set up near the reactor buildings. Toshiba says this work will take 5 years.

The final phase, dismantling the reactors and clearing the land, will take another 5 years. Toshiba says that radioactive substances released in the process must be removed during this phase.

The second article on NHK reveals that the first phase will only focus on stopping the leak from increasing will take 3 months.

Stabilizing nuclear fuel could take long

Japanese nuclear scientists say if a cooling system can be put in place at the Fukushima Daiichi plant, stabilizing its nuclear fuel could take another 3 months.

The deputy head of the Atomic Energy Society of Japan, Takashi Sawada, released the projection by an informal group of 11 society members on Thursday.

He said data published by Tokyo Electric Power Company shows that parts of the fuel rods in reactors 1 and 3 have melted and settled at the bottom of the pressure vessels.

He said if the ongoing water injections continue, the current situation can be maintained.

He said Tepco’s most important task is to remove all the contaminated water and rebuild a cooling water circulation system.

He said once these jobs are done, stabilizing the nuclear fuels could take 2 to 3 months, if not longer.

But he warned that the situation could deteriorate if another strong earthquake knocks out power to the plant and makes it impossible to keep the nuclear fuel cool for 2 or 3 days. That would destabilize temperatures and pressures inside the reactors, and the situation would become extremely unpredictable again.

No wonder Japan is mulling over plans to evacuate the government and not the residents 6 hours away, by car, from the Fukushima nuclear power plant.

There is also news that the Prime Minister of Japan has left the country for a G7 and a G20 meeting to discuss the nuclear crisis.
