building a liquid fluoride thorium reactor. a 2-3 kilowatt hour type thing, very small core.

what's a LFTR you ask? watch this

i called the NRC and oak ridge, turns out it's legal to own about 200 grams of uranium 233 (the primary fissile material). half a pound of fuel should do me well. As for thorium, i'm not really sure.

However i'm still not sure where i can get/make some nuclear grade graphite for the core moderator or some Hastelloy-N to coat the interior of the pipes and machinery.

<--- this is my super ultra basic layout. i might remove the beryllium tower assembly and just let the Pa233 decay in the thorium blanket and continuously gasify the U233 out of the blanket.

so, tl'dr, questions;
1) any places i can get hastelloy-N? perhaps some metallurgy places that could make it from scratch? or even better, guides to make it yourself?

2) places to get some nuclear grade graphite? perhaps from a university?

3)places to get thorium?, easy version would be thorium nitrate which is used (i believe) as a detector of specific minerals in water lines. but i don't know where to get a lot of that.
