He said the company would continue to gather data for its studies and said he wasn't considering filing a lawsuit against the government or shutting down the reactor at this stage.
Because this was a reactor that operated on water that was already at its boiling point, this also meant that the pressure inside the reactor was rising as well.

This reactor does not use fission, the process of splitting atoms into smaller elements employed by every commercial power reactor currently operating on earth.

Ironically, confirmation of the reactor delay makes this harder to avoid.
The optimist and competent decision makers at Petrobras did not plan to leave this reactor sitting at the port but since Rio de Janeiro highways do not support the weight of the equipment, well it is stuck there.
What makes this incredible reactor so different is its fuel source: thorium.
FORBES: Is Thorium the Biggest Energy Breakthrough Since Fire? Possibly.
Even when we were touring this decommissioned reactor, we got a good flavor for the constant upgrade of safety during the lifetime of that reactor.
Under the proposal, Iran would get the fuel it needs for its research reactor in Tehran, but this would not be sufficiently enriched to make a bomb.
There are various advantages cited for this type of reactor, including the claim that it can be stopped easily if things get out of hand, and that it produces less long-lived nuclear waste than the uranium-fuelled fission reactors that are currently in common use.
This time, say reactor vendors and big engineering and construction firms hoping to do the building, things will be different.
David Sanderson, a physicist at the Scottish universities' research and reactor centre, says that while this would need heavy investment (and a lot of workers), plutonium can be mixed with waste and vitrified into storable glass blocks, so making it unusable in bombs if any terrorists managed to steal some.
One of them, Rear Admiral Simon Lister, is in charge of this complex programme, and as he took me round the cramped corridors, past the nuclear reactor and down into the sweaty machine rooms, he acknowledged this was a prototype and there was always going to be some "teething" issues.
Considering that at least one person, a worker in the reactor, has died so far, this incident appears to be worse than Three Mile Island.
The last operational reactor in Japan is due to be switched off in May this year.
This is the stuff that atomic bombs and nuclear reactor fuel are made from.
And he understood this, but he went, he walked from the reactor itself and then out through all the sectors around the radius of radioactivity.
This technique will be used in the 10bn-euro Iter reactor currently being built in Cadarache, southern France.
This caused the explosions that destroyed the buildings and damaged the reactor vessels that are meant to keep radiation from getting out.
This was believed to be originating from an area near a reactor.
FORBES: Media Hype Over Nuclear Energy Increases Anxiety And Confusion
This came close to exploding and blowing the plutonium-fuelled reactor to smithereens.
With the blended reactor, the neutrons from fusion reactions would wedge themselves into the nuclei of this waste, making them unstable enough to split and produce heat.
Enter web-comic celebrity Randall Munroe (of xkcd), and his friend Ellen, Senior Reactor Operator at the Reed Research Reactor, who have put together some charts which might help us make sense of all this radiation talk.
Current designs can produce two kilowatts per cubic meter of liquid reactor volume and without any drawbacks (some models produce methane as a by-product, this tech does not).

Conceptually, I think this is a cool idea, allowing for both flexible power construction and a very safe reactor design.
"This is not a footnote in a license as Edison claims, but a severely damaged reactor that is unsafe to operate, " Ulrich said.
This rectangular secondary containment building is the structure that most people have seen in pictures of the reactor.
FORBES: Explainer: What Caused The Incident At Fukushima-Daiichi
This should also be an opportunity for Westinghouse, which has designed the third-generation AP1000 reactor to shut down safely even in the event of complete loss of electric power.
Reactor operators typically discharge about one-third of the fuel assemblies every 18 months to 2 years and place this spent fuel in a pool to cool .
This process could result in a piecemeal assemblage of potentially incompatible parts of dubious reliability in an untested reactor of questionable technology with no operational track record.
