استخدم نوعان من المفاعل السريع المبرد بالرصاص لتشغيل [[غواصة|الغواصات ]] السوفيتية من التصنيف ألفا Alfa class submarine خلال السبعينيات من القرن الماضي . وكان تصميم كل من المفاعلين OK-550 و BM-40A بحيث ينتج كل منهما 155 ميجاوات.طن (وقود). مكانا أخف كثيرا عن مفاعل الماء الخفيف

Two types of LFR reactor were used in [[Soviet Navy|Soviet]] [[Alfa class submarine]]s of the 1970s. The [[OK-550 reactor|OK-550]] and [[BM-40A reactor|BM-40A]] designs were both capable of producing 155MWt. They were significantly lighter than typical water-cooled reactors and had an advantage of being capable to quickly switch between maximum power and minimum noise operation modes, but lacked reliability, as solidifying of lead-bismuth solution turned the reactor inoperable. However, [[lead-bismuth eutectic]] has a very low melting temperature, {{convert|123.5|C|F}}, making desolidification a relatively easily accomplished task.
 
A joint venture called AKME Engineering was announced on 25 December 2009 between [[Rosatom]] and [[En+ Group]], to develop a commercial lead-bismuth reactor.<ref name="SVBR100">{{cite web | url=http://www.world-nuclear-news.org/NN_Initiative_for_small_fast_reactors_0401102.html | title=Initiative for small fast reactors | date=2010-01-04 | publisher=World Nuclear News | accessdate=2010-02-05}}</ref> The SVBR-100 ('Svintsovo-Vismutovyi Bystryi Reaktor' - lead-bismuth fast reactor) is based on the Alfa designs and will produce 100MWe electricity from gross thermal power of 280MWt,<ref name="SVBR100" /> about twice that of the submarine reactors. They can also be used in groups of up to 16 if more power is required.<ref name="SVBR100" /> The coolant increases from {{convert|345|C|F}} to {{convert|495|C|F}} as it goes through the core.<ref name="SVBR100" /> Uranium oxide enriched to 16.5% U-235 could be used as fuel, and refuelling would be required every 7-8 years.<ref name="SVBR100" /> A prototype is planned for 2019.
