WTF is a temporarily melted fuel rod

The BS is getting deeper.
This is crap.
The public does not have the technical knowledge to understand this.
They rely-on and need transparent info.
They are not getting it here.
This whole thing is really starting to stink big-time.
And then they say this is an "unknown" route. BS.
They know dam well it is a cracked containment vessel.
They have been warned of embrittlement for over a decade.
And you know what, same problem here.

Radiation hampers cooling efforts
The effort to cool reactors at the damaged nuclear power plant in Fukushima, northern Japan, is facing the risk of leaking highly radioactive substances.
The plant's operator, Tokyo Electric Power Company, raised water pumping power on Sunday to cool the No. 2 reactor in a stable manner. On Monday, the company cut back on the amount of injected water.
The move followed the Nuclear Safety Commission's announcement that highly radioactive substances detected in puddles of water in the basement of the reactor's turbine building may have come directly from the vessel containing the reactor.
16 tons of water was being injected into the reactor every hour but TEPCO now says it wants to reduce the amount to 7 tons. This would be enough to replace the amount that is evaporating.
If the injected water level is reduced, temperatures may increase in the reactor.
TEPCO announced on Monday that radioactive substances 100,000 times higher than usual for water in a reactor core were detected in puddles in the No. 2 reactor's turbine building on Sunday.
High radiation figures were also recorded earlier in water in the basements of the turbine buildings for the No. 1 and No. 3 reactors. On Thursday, 3 workers were exposed to high radiation while working in water at the No. 3 reactor's turbine building.
The Nuclear Safety Commission said on Monday that the concentration of radiation at the No. 2 reactor was dozens of times higher than the other 2 reactors.
The commission said it assumes that radioactive substances from temporarily melted fuel rods at the No. 2 reactor had made their way into water in the reactor containment vessel and then leaked out through an unknown route.
TEPCO, later, reported that very high levels of radiation have also been observed in water in a trench just outside the turbine building for one of the reactors.
The commission said the biggest concern is the possibility of highly radioactive water seeping into the ground and the ocean. It added that all-out efforts should be made to prevent contaminated water from leaking and called on the government to intensify monitoring radiation levels in the ground water and seawater.
