Nuclear energy collectibles

It's very interesting to me to know if there are PROS members who collect different items connected with nuclear power stations and nuclear energy in general - such as medals, coins, awards, badges etc. Spent fuel assemblies are out question . I'm sure the forum will help us to broaden the circle of collectors. I'll be able to show something new from USSR and ex-USSR countries. Sorry for possible mistakes in my English.
