Question about the building and containment construction regarding the diagram in post 1906. https://www.physicsforums.com/showpost.php?p=3217183&postcount=1906 Is there another enclosing structure not shown in this diagram between 30, 38 and the outside building wall (that was destroyed)...

I have looked at this over the past few days and it seems that examining a specific detail leaves out other factors to the extent that one misses the big picture. A lot of links have been provided. This one has navigational links on the left to explore including detection and treatment...

Alpha radiation though is not penetrating i.e. it’s easily stopped by skin, clothing, paper pretty much anything. The danger is in ingesting/inhaling it or otherwise introducing internally. http://orise.orau.gov/reacts/guide/alpha.htm I think (please correct me if I’m wrong as I am just...

Astronuc, 

 Would you be able to render an opinion on the Ukrainian proposal to cool the reactors with liquid metal (Tin). I find this idea very intriguing and would like to hear others thoughts on the matter. On 17 March, KyivPost reported that a Ukrainian group of specialists who...

Assuming (given) there is fission... what do they do to stop it? Watering just appears to be making a mess.

Any thoughts about using Liquid Gallium for the Spent Pool cooling. Gallium melts at ~29.76C (85.57F) and boiling point at 2204C/3999F. I think you could easily add a heat exchanger to the spent pool.

Could you fill the RPV with LM and let the heat transfer to the flooded containment through the RPV wall? I don't know.. is there a heat exchanger in the RPV for say steam to the turbine?

Some other references I read on the topic of Liquid Metal cooled reactors indicated that LM cooled reactors have been used/studied for 50 years. Sodium seems to be the most predominate probably because of the temperature range and thermal transfer properties.

I have a couple of cooling questions. In a document I read it was indicated that Liquid Tin with inert gases could be injected to cool the reactor. Actually I think it said chopped tin but the idea was taken from Chernobyl where they used lead to cool the remains before the entombment with...

Can anyone direct me to information that would help quantify the differences in meltdown scenarios between MOX and non MOX fuel reactors? i.e. all things being equal what is the additional risk? Can we reasonably quantify it as some percent (5%) worse due to higher PU levels? TIA, DWB
