Fukushima Nuclear Accident Update Log
While there are panic reports and rumors out that the reactor core is breached, that’s highly unlikely since we would have continual reports of persistent high radiation leaks if that were the case. The high radiation puddle referenced in the reports most likely was the result of pumping 120 tons of seawater into the spent fuel cooling pool at #3, or a plumbing leak, see below. I’m no expert, but a full core breach is neither indicated nor likely.
At Unit 1 workers have advanced the restoration of off-site electricity and lighting in the Unit’s main control room was recovered as of 24 March, 11:30 UTC. They are now checking the availability of the cooling system.
While the pressure in the reactor vessel remains high, Japanese authorities are reporting that it has stabilized.
At Unit 2 engineers are working for the recovery of lighting in the main control room, and the instrumentation and cooling systems.
At Unit 3, around 120 tonnes of seawater was injected in the spent fuel pool via the cooling and purification line. The operation was carried out between 23 March, 20:35 UTC and 24 March, 07:05 UTC.
Work was under way for the recovery of the instruments and cooling systems. However, it had to be suspended because three workers were exposed to elevated levels of radiation on 24 March.
