running at high temperatures mean you could use the heat to run a chemical factory and could possibly make hydrogen thermally (though it does involve sulfuric acid at 850 °C which will eat most reaction vessels) or possibly fit a gas turbine powerset which, together with compact heat exchangers, could possibly get capital cost under the LWR:

Higher temperatures could even improve the efficiency and reduce the cost of a steam turbine.
