You can still visit Sizewell B, the plant in the article. I visited last year.

Two very knowledgeable guides led our group of 4 on a 3-4 hour tour of the facility, including the turbine hall.

In France too, and they have an efficient way of solving the “what if there are terrorists among the visitors” problem: the groups are escorted by armed members of the French special forces (there's an on-site platoon of them on every nuclear site to act as a rapid reaction force).

I did too. I also visited Hinckley Point as a teenager, but for that we could just turn up whereas for last year's trip we had to book well in advance and submit ID information for vetting.
