Some facilities have guided tours at times but generally, no they are not open to the public.
There is a planned family day for employees. However for employees only. They do tours for city officials, emergency personnel and such, but not for individuals as of right now. You can always call the facility itself and ask if they have future planned tours.
As of right now the answer would be no. They have mentioned in the future, the possibility of doing a tour. But im not sure of when they could start, if they decide to.
