The CEO COSCO, a large chinese shipping company, has stated a serious interest in nuclear powered commercial shipping. There have been detailed financial studies done. A study showed that a nuclear ship would be $40 million per year cheaper to operate when bunker oil is at $500/ton. Those studies had indicated improved economics when bunker fuel is over $300/ton. Bunker oil is currently about $375/ton.
