Page "D2G reactor" Paragraph 5

Rated for a maximum thermal output of 150 megawatts, the reactors were designed to last 15 years with normal usage.

The Navy's nuclear cruisers were outfitted with two reactors per ship, each having the ability to cross-connect the steam and condensate systems between plants to power both engine rooms from a single reactor.

With both reactors running and the steam plants split, the average cruiser could reach 32 knots ( 59. 2 km / h ).

With one reactor running and the steam plants cross-connected, the ship could reach 25 – 27 knots ( 46. 3 – 50 km / h ).

With one reactor running, the steam plants split, and running on one shaft, the ship could reach only 15 knots ( 27. 7 km / h ).
