Following up this article.. M4.6 hit Hamadori Fukushima / Seismic intensity 4 [URL]

 

From NRA (Nuclear Regulation Authority)’s real time monitoring data (Graphs attached below), radiation levels spiked up when the earthquake occurred.

The area is Southern part of Fukushima prefecture. 3 municipalities experienced the rapid increase of the atmospheric dose up to 54%.

 

The increase started around 16:30 and had the peak when M4.6 occurred. It went back to the normal level around 19:00.

 

Observing the spikes in 3 municipalities in the same area of Fukushima, it can be difficult to judge it was merely a malfunction of the monitoring posts.

There is a possibility that small quakes have been occurring before M4.6 hit and those lead to the increase in the radiation level.

 

However Tepco hasn’t announced any abnormality about the plant status.

Selon les données de surveillance en temps réel de la NRA (Nuclear Regulation Authority), il y a eu un pic de radioactivité au moment du séisme (Graphiques ci-dessous).
C’est dans la région Sud de la préfecture de Fukushima. 3 municipalités ont vu rapidement monter leur radioactivité ambiante jusqu’à 54%.

Le pic a été amorcé vers 16:30 et il correspond au moment du séisme M4.6. C’est revenu à la normale vers 19:00.

En examinant les pics des 3 municipalités de la même région de Fukushima, il est difficile de déterminer s’il y a eu dysfonctionnement des bornes de surveillance.
Il est possible que de petits séismes se soient produits avant ce M4,6 et qu’ils soient à l’origine de ce pic de radioactivité.

Tepco n’a néanmoins pas annoncé de problème particulier quant à l’état de la centrale.

    The fact that these spikes occurred in near-identical timeframes suggests that they were caused by local factors such as the displacement of dust rather than by new releases from the plant.

    Undetermined, as yet

    Nuclear Power Plants routinely increase radioactive releases, when operational output/throughput levels are adjusted. So, for example, a 5 C temperature change (rise), may produce a 10% electrical power increase. The mechanical stresses and strains, due to heat expansion; ‘routinely’ cause a significant SPIKE in radioactive releases, of every sort.

    The nuclear power plant will gradually (thermally) stabilize; which results in a reduction in radiation releases. These nasty behemoths CONTINUALLY shower radioisotopes and nuclear particles/waves across the surrounding countryside.

    The dynamic leakage of pressure vessels, during operational adjustments is a general phenomenon. It is common for compressed fluids to leak when the plumbing is ‘jostled’. Move a garden hose and water may spurt from the connections and then quit, when the movement stops. Hydraulic oil may spurt, when a bulldozer or tractor equipment is rotated, extended or withdrawn.

    Thus, the observed radioactive spikes may relate to new releases and/or disturbance of older releases.

      Agreed. I was assuming that if new releases were involved, they would have taken different lengths of time to reach the three measuring points. But if the measuring points were sufficiently close together and if the releases were sufficiently widespread, the time difference might not be observable on the charts above. There is plenty of evidence that new releases are occurring frequently and are probably ongoing.
