Reactor power output[edit]

According to the MIT article previously cited [1], the reactor has a thermal output of 220MW and a shaft power output of 57000shp. However, an article from Global Security [2] states that the S6W has a thermal output of 270MW and a shaft power output of 52000shp. Currently, I’ve continued to use the figures from the MIT article while adding the Global Security article’s information on the steam turbines and the natural circulation. Nevertheless, I would like some input on how to reconcile these two conflicting sources. Thanks! Liu1126 (talk) 12:26, 23 January 2023 (UTC)[reply]

I can't answer your question, but are those numbers correct? They imply a thermal efficiency of only 26%, which seems very low for a steam turbine power plant. GA-RT-22 (talk) 14:09, 23 January 2023 (UTC)[reply]

Low efficiency seems to be a trend among naval reactors (like the S9G, A1B, S6G), which I also find quite odd. My best guess is that either significant amounts of power are diverted to electric generation which might not be included in shaft power, or the heat transfer in the steam generator between the reactor coolant and the secondary coolant (the water that actually goes into the turbines) isn't very efficient.

I was just made aware that there was a RFC on globalsecurity.org before that decided it was a generally unreliable source. In this case, it would be best to go with the MIT article, so I’ll keep it as it is. Liu1126 (talk) 06:11, 24 January 2023 (UTC)[reply]
