Fukushima’s Reactor #2 is far more radioactive than previously realized
Extreme Tech ^ | 2/3/17 | Joel Hruska

Earlier this week, Tepco, the Japanese company in charge of cleanup operations at Fukushima Daiichi, seemed to be on the verge of announcing rare good news. Specifically, the company had found some of the fuel debris associated with the failure of Reactor #2 at the bottom of the reactor’s containment vessel. Locating the damaged reactor’s fuel (or what’s left of it) is critical to the clean-up effort.

What the company ultimately discovered, however, is that the amount of radiation pouring off the damaged reactor below the reactor pressure vessel is 530 sieverts per hour, vastly higher than had previously been communicated. Previous measurements of the radiation inside the containment vessel had pointed to an exposure level of 73 sieverts per hour.

One thing I want to note at this point is these findings are being misreported across the internet as evidence Fukushima’s radiation output is “spiking” or “soaring.” This is not the case. The radiation levels within Reactor #2’s containment vessel have been largely unknown for years, due to the difficulty of getting proper readings from remote equipment in the first place. The entire reason Tepco used muon tomography to examine the interior of both Reactor #1 and Reactor #2 was because they didn’t have another means of identifying where fuel was inside the reactors. The 73 sievert metric is mentioned in reports dating back to 2012 — I’m not sure when or how Tepco measured it, but implying this is a sudden leap in radiation output is simply inaccurate.

“Unexpected”

Leaking into the Pacific, I’m sure.

Couldn’t the Japanese organize a banzai charge and rush the reactors and dismantle them and toss the debris and radioactive bodies into an deep ocean trench?

Or are they worried about awakening Godzilla with all the radiation.

At the level of radiation quoted in the article, any human would be dead in well under a minute. In fact, radiation levels are so high it’s impossible for ROBOTS to get close to the reactor without frying.

They need better robots. Of course, they’re probably the best in the world at making robots or close to it.

It IS a nuclear reactor. How much more radioactive do they expect it to be?

Sounds like the containment building did what it was designed to do and contained more of the fuel than expected... Hence higher residual radiation readings.

Integrated-circuit chips would need heavy shielding to survive more than a limited time. If they were designing for one level of radiation and got a much higher one on then the life of the robot would be limited. I would think that the robot — once ‘dead’ — is sealed in a drum and treated like spent fuel.

“Suddenly” (since Trump’s election).

Sounds like the leftist freak Hussein Heads who reported on how great the economy was doing for eight years despite “unexpected” unemployment rates were also cooking Fukushima’s books.
