@fitter, nitrous oxide, aka laughing gas, is used to supplement oxygen in rocket engines. It seems to work like oxygen at higher temps. Probably, it also corrodes the tanks.

@elainekirk looks like the bolting machine for reator or containment lid... I call it the spider machine in her pic's

@fitter Still talking about the oxides of nitrogen I see. Ok here's the low down on that. Nitrogen is only a semi-inert gas, it does form oxides but has to have an input of energy to do so. The energy can be in many forms, could be sunlight, the cylinder of an internal combustion engine, or any form of energy that forces the formation of that compound. It is an endothermic reaction meaning that it requires energy foe its formation--it is "up the hill". Once these types of compounds are formed, they are relatively unstable and break down with a release of energy--"down the hill". This is the reason why many compounds of nitrogen are good explosives.

@LM sounds like something we should push congress on.

@Markfm @Jim Carver thanks air products is one of my vendeos...

From the Safetygram (the link), about nitrous oxide, "Nitrous oxide is nonflammable, but is an oxidizer that can cause or intensify fires. At elevated temperatures, nitrous oxide decomposes. The decomposition reaction is exothermic" ... "The tendency for decomposition increases as temperature, pressure and energy input increase,"

@Markfm I would relate this to being a oxgen enriched enviroment...(not correct chemicaly) but same theroy and outcome?????

Yes, it adds to the explosion, once something has already started -- another source of heat plus more oxygen. (JC, please correct me if I'm wrong.)

That's why I included the source reference -- overall I found the Safetygram pretty decent reading, barring that error.

@jim also

@fitter I really don't know their plan well enough to comment right now.

@Jim Carver were would you look to try and find a formula of what is needed to be know to determine ... the amout of gas and what gases would come from the sludge reciver and how long it would take to create an explosive astmp.

@fitter Absolutely could have been an accelerant, that's why I questioned the use of it in cooling the reactor chamber instead of using argon. Dean said normal practice was to use argon and helium.

Electronic surveillance primarily, years of comms, cameras, radars, computers, many oddball sensors.

@Markfm sound intersting field

Pays the bills, beats doing real work.

@Jim Carver the oxides being the "common thread" in these gas... would that be somewhat correct

@fitter yes along with other nitrides that could be unstable.

I still haven't seen anything discussing nitrogen and cooling. All references I saw were related to trying to "safe" the containment buildings by adding nitrogen to inert the air in them. They use nitrogen injection on supertankers, in the holds, which is probably why it came up -- probably not hard to get access to one of those units.

@Markfm I think they were just being cheap as usual, just a cheap way to dilute the atmosphere inside the reactor. Guess it worked, they haven't blow up yet.

CO2 is pretty darn stable.
