The French nuclear plants have an average capacity factor of ~70%, the Swedish plants around 80%. It seems most prudent to assume a nuclear plant in Denmark would be at a similar level.

And if you want to use the plant in a dispatchable pattern, you'll be turning it off a lot when the sun is out and the wind is blowing, further decreasing capacity factor and increasing the LCOE.

I get that there's a lot of R&D going on to make larger quantum computers a thing and that there's been very definite progress, but factoring 21 is just too hard to expect for now. But that also pushes the date where pre-quantum cryptography is broken further into the future. If we still struggle to factor one of the smaller 5 bit numbers, factoring the 128 bit numbers necessary to break elliptic curve cryptography seems quite far away.

0: OK, there are some additional non-ASCII Unicode symbols, but everything but string literals should be kept ASCII IMO.

Why Carl Zeiss is an AG I don't know. The West German Carl Zeiss was re-formed as a GmbH in 1946, but had changed to an AG by 1973. The East German Carl Zeiss was turned into a GmbH during reunification and then split in two. One part merged into the West German Carl Zeiss AG and the other is now called Jenoptik. Jenoptik was converted into an AG in 1996 and went public in 1998. AFAICT Carl Zeiss has been privately owned by the Carl Zeiss-Stiftung since 1889, except of course for the temporary East German part.

And to nitpick: INSAG-7 doesn't disagree with INSAG-1 about the power rising just before AZ-5. From page 8 of INSAG-7: "When the turbine was tripped, the four pumps it was powering began to slow down as the turbine speed was reduced and the associated generator voltage fell. This reduced rate of core flow caused the void content of the core to rise and caused an initial positive feedback of reactivity which was at least in part the cause of the acci- dent." (page 8) This happens ~30 seconds before AZ-5 is pushed.

The same event described in Table I on page 21-22 of INSAG-1, with the part deprecated by INSAG-7 marked with {}:

01:23:04 {The personnel blocked the two-TG trip signal.} Emergency stop valve to the turbine was closed. The reactor continues operating at a power of 200 MW(th).

01:23:10 One group of automatic control rods start driving out

01:23:21 Two groups of automatic control rods begin reinsertion.

01:23:31 Net reactivity increasing with subsequent slow increase in reactor power.

01:23:40 Operator pushes AZ-5 button (reactor trip).

The textual description on page 25 of INSAG-1 isn't much different: "When the emergency stop valve to the turbine was closed, the steam pressure began to rise. The flow through the core started to drop because four of the main cooling pumps were running down with the generator. Increasing pressure, reduced feedwater flow and reduced flow through the reactor are competing factors which determine the volumetric steam quality and hence the power of the reactor. It should be emphasized that the reactor was then in such a state that small changes in power would have led to much larger changes in steam void, with consequent power increases. The combination of these factors ultimately led to a power increase begninning at about 01:23:30."
