The coolant options listed for liquid-metal reactors include mercury, sodium, a sodium-potassium alloy, lead-bismuth, and tin. Tin is described as a specialist option under investigation, rather than an established naval coolant. Possible reactor demand is offered as one contributor to rising tin prices. The discussion links that interest with Cornwall's tin-mining industry and the reopening of mines.
