This is said a lot but I don't think regs as written are necessarily the major cost driver. I did a nuclear industry survey to ask what specific regulations people would want changed recently. The one where using commercial grade QA instead of nuclear grade is very interesting.
I think industry overreaction to the regs is possibly as large or larger of a problem than the regs themselves.

I'm a bit miffed I can't find the article now, but I recall hearing it was more the reactor design approval process than the operational process regulations that interfered with and drove up costs. Every tiny detail of a site has to be taken into account, forcing modifications to existing designs such that every build ends up being bespoke anyway. On top of that, many of the rules around the design approval process are geared towards older generation reactors and newer generation reactors end up being cost ineffective because they need to account for things that don't apply to them.
If anyone remembers that article, I'd love to cite it here. If not, feel free to ignore what is otherwise unfounded speculation I guess.
Maybe this article?

There is some regulatory burden for sure. But the NRC has been very conducive to standardization, and approved construction and operation licenses of like 20 brand new latest generation water-cooled reactors in the first nuclear Renaissance (2006). It was Fukushima and fracking that killed that Renaissance, not regulations.

The NRC has also been generous with advanced reactor licenses, granting construction licenses for the Kairos Hermes 1 and 2 molten salt cooled test reactors recently. And one for the Abilene Christian university's molten salt fueled reactor too!

A lot of the tech world got it in their heads that nuclear regs are the main issue in nuclear when in reality it is still megaprojects construction management. The small advanced reactors are likely to be very expensive per kWh

It was mostly fracking. Most plans for new builds had already been put on hold by the time Fukushima occurred. New nuclear in the US made zero sense when gas is cheap and combined cycle power plants are 10% of the capex/power.
And since then, renewables and storage have crashed in price, nailing shut nuclear's coffin lid.

I see this over and over again in regulated industries like banking and healthcare. No one wants to risk tripping up the regulations so company lawyers write up crazy and often conflicting “requirements” to satisfy legislation. The limitations placed by company council are often far more restrictive than regulations actually require. You have lawyers dictating engineering or software design requirements based off of a shoddy understanding of other lawyers attempts to regulate said industries they also don’t really understand.
And this isn’t to say that engineers are somehow better at this than lawyers. Engineers make just as many of these sorts of mistakes when developing things via a game of telephone. As someone who has played the architect role at many companies, it’s not enough to set a standard. You have to evangelize the standard and demonstrate why it works to get buy in from the various teams. You have to work with those teams to help them through the hurdles. Especially if you’re dealing with new paradigms. I don’t know to what degree this happens for other industry standards. But it seems like mostly folks are left to figure it out themselves and risk getting fined or worse if they misinterpreted something along the way.
I’d like to believe there is a way to balance lenience for companies that are genuinely trying to adhere to regulations but miss the mark at places and severely cracking down on companies that routinely operate in grey areas as a matter of course. But humans suck. And lenience given is just more grey areas for the fuck heads to play in. We cannot have nice things.
I have ideas of a plan to help in nuclear, which is to make open source reactor company quality assurance and engineering procedures that establish clear compliance with regs but also incorporate all sorts of efficiency lessons learned
