Heat Buffering Maths
Circuit Controller
I believe this principle (essentially upgrading a dumb reactor with a steam measuring tank and some smart circuitry) would scale up quite well. Reactors in long 2x rows do put out as much as twice as much energy per fuel cycle, though they also need twice as many heat pipes and heat exchangers which largely balances that out - the only which doesn't is the reactors still having the same heat capacity. I believe that (extra) steam storage tanks should generally not be required for larger nuclear setups under reasonable loading (i.e. at least 30% base load). Using double rows of heat pipes instead of a single row would also be a way to provide ample heat buffering, and it's a nice compact solution as heat pipes provide twice the heat storage density as steam tanks (3x3 heat pipes = 5GJ, 1 steam tank = 2.4GJ). Ultimately whether or not a reactor will successfully buffer a full heat cycle at any load is not a problem which can be solved simply by maths, you need to run the reactor at a given load and see if the reactors reach 1000 degrees - but my experience is the heat transfer is usually fast enough that under reasonable loads no heat is wasted.
